How does the tank truck work?

The tank truck body structure of the tanker is an elliptical cylindrical or trapezoidal cylindrical body, made of high-quality steel plate. The whole tank body is divided into single or multiple warehouses. The inside of the tank can be divided into compartments. The lower end of the intermediate partition has a through hole, and the middle of each warehouse is welded. Separate bins or multiple bins, the bins can be divided into compartments, the lower end of the middle partition has a through hole, and the sub-bin reinforced wave partition is welded in the middle of each bin to reduce the impact of the oil in the tank when the car is sucked and improve the rigidity of the tank.

Operation Guide for Tank Truck

tank truck

1. In order to ensure the cleanliness of the tanker, the tank and the oil delivery system should be cleaned regularly, and the internal and external joints at both ends of the oil delivery hose should be frequently coated with lubricating oil, so that the tanker is easy to disassemble and assemble. After each work, the tubing should be cleaned in time to ensure that the tubing is clean;

2. The use and maintenance of the oil pump of the oil tanker shall be carried out in strict accordance with its operation and maintenance manual;

3. Before refueling operations, you must use a power pole to insert into the damp ground, the tank truck grounding tape should be grounded, and the static electricity should be maintained during the operation;

4. The safety valve and filter net of oil tanker should be checked and cleaned frequently;

5. Oil tanks and piping systems should be cleaned regularly. The tank truck regularly checks whether the joints of the pipeline system are well connected and the seal is reliable.

Working principle of tank truck

tank truck

In order to ensure that the pressure in the tank is basically the same as the atmospheric pressure during the working process of the tanker, a breathing valve is installed on the large cover of the large tank. When the oil in the tank is heated to expand or when the oil pump is used to refuel the tank, the oil level in the tank rises. The pressure increases. When the pressure in the tank is higher than the external pressure by 8KPa, the upper valve plate of the breathing valve opens; when the oil is discharged from the oil pump or the oil is cold contracted, the oil level drops and the pressure decreases. When the pressure in the tank is lower than the outside pressure 3kpa, account opening under the breathing valve.

Oil pump operation

1. Start: Connect the relevant pipelines, start the engine. When the main reading of the original car pressure gauge reaches 0.3Pa, step on the clutch pedal, turn on the power take-off box control switch, and put it into gear. Through the throttle controller, the working speed of the oil pump can be controlled.

2. Stop: Push the throttle controller to the minimum, depress the clutch pedal, return the power take-off control plate to the original position, and make the power take-off box out of gear.

What are the precautions during the loading and unloading of tank trucks

The tank structure of the tank truck is an elliptical cylindrical or trapezoidal cylindrical body, made of high-quality steel plate. The whole tank body is divided into single or multiple warehouses. The warehouse can be divided into chambers. The lower end of the intermediate partition has a through hole. There are divided warehouses or multiple warehouses. The warehouses can be divided into compartments. There is a through hole at the lower end of the middle partition. The middle of each warehouse is welded with a partition reinforced wave partition to reduce the impact of the oil in the tank when the car is sucked and improve the rigidity of the tank.

We have introduced the process of loading and unloading oil on tank trucks before. In order to reduce the occurrence of tank truck loading and unloading accidents, we hereby give the following detailed descriptions of several precautions for tank truck loading and unloading operations:

tank truck

Safety technical measures

(1) Reliable electrical connections and grounding should be made between the loading and unloading facilities of automobile tank trucks, including crane pipes, oil pipelines, and metal oil loading platforms.

(2) Ground scales, crane pipes, fuel guns, pipelines, etc. at the oil loading and unloading site should be bridged and equipped with electrostatic grounding devices. The grounding resistance is not more than 1002.

(3) The fuel delivery site of the automobile tanker should be equipped with a copper core soft stranded wire with a cross-sectional area of ​​not less than 4mm2, one end of which is connected to a crocodile clamp that can break the paint, a special connecting clamp, etc., so as to be connected with the body of the tanker; The other end should be connected to a grounding device.

(4) Automobile tank trucks used to transport refined oil should use rubber towing belts, and metal towing belts are prohibited.

(5) A baffle should be installed in the oil tank of an automobile tanker. It is forbidden to use non-baffle tank trucks to transport easy fuel products.

(6) The resistance between the oil tank and the car body shall not be greater than 106Ω. The resistance value of the conductive path between any two points in the metal pipeline or on the conductive parts inside the oil tank and the end of the mopping tape shall not exceed 5Ω.

(7) When filling the tanker with oil, the maximum safe flow rate of crane pipes with different diameters should meet:

Oil filling method 80 90 100 110 120 150

Oil filling at the top (the numbers in parentheses are the corresponding flow m/s): 6.0 (110) 5.5 (125) 5.0 (140) 4.5 (155) 4.2 (170) 3.3 (210)

(8) The connection between the electrostatic grounding wire and the tank car should meet the following requirements.

① The connection should be tight and reliable, and winding connection is not allowed.

②Connect before opening the tank lid.

③It must be connected to the special ground terminal board of the tanker, etc., and not within 1.5m of the loading and unloading oil port.

④Remove the connection after closing the tank lid.

(9) During the operation, the loading and unloading of light oil should be carried out in strict accordance with the relevant operating procedures. It is strictly forbidden to conduct gauge, temperature measurement, sampling, or insert other objects into the tank after 2 minutes of unstable oil.

(10) When the tanker uses top-loading oil, the oil-loading crane pipe should go deep to the bottom of the tank, and the distance from the bottom of the tank should not be greater than 200mm. Splashing light oil is strictly prohibited.

(11) When replacing oil tanks with high volatility oil products (including tank cars) with low volatility oil products, the concentration of oil and gas in the tank should be detected. When the concentration of oil and gas exceeds 25% of the lower explosive limit, ventilation or cleaning should be carried out.

(12) In the process of loading and unloading flammable fuel products, no field test or test that may generate static ignition sparks is not allowed without approval.

(13) It is strictly forbidden to wipe and test vehicles, objects or the ground in the workplace, and conduct various temporary operations that may cause electrostatic hazards.

Septic tank truck

Safety precautions

1. Operators should wear clothes and shoes that can discharge static electricity.

2. Use tools that do not produce sparks.

3. It is forbidden to work during thunderstorms.

4. Pay attention to prevent oil spills.

5. When oil spills or oil leaks are found, all oil filling operations at the oil filling point and adjacent oil filling positions should be stopped immediately. All valves that are open when unloading or loading oil from the bottom should be closed. Only key personnel should be left on the oil loading platform. Do not operate the starter of the vehicle until the spilled oil is cleaned up. The oil filling shall not be resumed until the person in charge of filling oil declares that the area is safe.

6. If a fire alarm occurs during oil loading and unloading, all operations should be stopped immediately, and unaffected vehicles should be driven away immediately. Close the oil tank valve to cut off the oil source, and immediately implement fire extinguishing operations.

7. Do not turn on the ignition switch for a long time after the car is stopped. A car once caught fire on its own in the garage. After investigation, it turned out that the ignition switch was still on after returning from the car last time. If it is turned on for a long time, it will not only cause the battery to discharge for a long time, but also cause the danger of fire.

Fuel tank truck

8. It is not allowed to implement “self-flowing oil supply” for a long time. Sometimes due to the damage of the gasoline pump or the damage of the oil pipeline joints, the gasoline pump cannot normally supply fuel to the carburetor, and it cannot be repaired temporarily.

Only emergency treatment and self-flow fuel supply can be taken to drive the car back to the yard or drive to repair plant. At present, for the purpose of fire prevention, the road traffic management regulations formulated by the state do not allow this method to be used.

9. Open flame is not allowed to observe the height of the battery liquid level at night. When driving, the battery is in an overcharged state, and the excessive hydrogen accumulated in the shell causes an explosion when it encounters an open flame. Therefore, the small holes on the battery cover must be kept unblocked.

What are the safety regulations for tank trucks?

Everyone knows that tank trucks are dangerous goods vehicles. Due to their particularity, the country strictly controls the safety of tank trucks. Therefore, everyone will be very cautious when transporting and operating the vehicle, and strictly follow the dangerous goods operation system. If the operation is improper, it will cause a lot of trouble and cause unnecessary losses. So what are the safety regulations for tank trucks?

Safety regulations for tank trucks

Gas-tank-truck

1. When using and refueling tank trucks, a dedicated person must be assigned to operate and be responsible, and the vehicle is not allowed to be used without permission.

2. The fueler must be specially trained, have a certain fire-fighting knowledge, have a strong sense of responsibility, and have a good professional ethics. Conscientiously implement the “three inspections a day” system to keep the cars clean and in good condition.

3. Before refueling, in addition to regular inspections as required, check the connections, valves, high-pressure protection valves, oil pipelines, fueling guns and other parts of the oil storage tank to confirm that all parts are normal and effective before starting use. .

4. Special storage carports should be set up for tank trucks, and the carports should be kept away from fire sources, and clear fire prohibition signs and fire extinguishing equipment should be set up.

5. When a vehicle is driving on the road, keep a safe speed, avoid other vehicles, choose a driving route, and try to avoid construction sites with open flames. When transporting oil in the rainy season, keep away from electrical equipment that is prone to sparks such as high-voltage lines and transformers.

6. During the refueling operation or the oil pump discharge process, no open flame is allowed to approach within 10 meters, smoking and electronic communication are prohibited.

7. During the operation of the tanker truck, once a diesel oil leak occurs, the leaking part should be checked immediately and emergency treatment should be carried out. At the same time, clean up the leaked diesel to avoid the open flame approaching fire. After an emergency occurs, the diesel fuel tanker should be inspected as a whole, and normal operations can be carried out after eliminating hidden dangers.

8. Do a good job of safety protection in special seasons. Sun protection measures should be taken in summer, and high-pressure valves and safety valves should be checked frequently to ensure effective use. In winter, when oil pipelines and valves are solidified or frozen, it is forbidden to use an open flame to bake and thaw.

9. After the tanker has been refueled, the ground must be disconnected after the fuel has stabilized for 5 minutes. After the oil is installed, the oil will flow in the tank, causing the oil surface potential to remain for a few minutes. In addition, check the valves and connections of all parts to avoid running, emitting, dripping, and leaking. The fuel dispenser must be locked and safety precautions must be taken.

Tank truck maintenance skills

Oil tank truck

1. Clean up the lubrication system of the engine when your tanker is traveling 5,000 to 10,000 kilometers. When the tanker is too noisy or has weak acceleration, it needs maintenance.

2. When the gearbox of the tanker truck changes gears slowly or the vehicle travel distance reaches 20,000 kilometers, you must pay attention to it and do some maintenance. If you find that the hydraulic system is leaking, you must clean up in time.

3. The power steering system, cooling system, and braking system of the tank truck also need to be replaced and overhauled within a specific mileage. Only in this way can the vehicle maintain good performance.

The above is the introduction to the safety regulations of refined oil trucks. Through reading, we have learned that tank truck fuelers must undergo special training. They should perform routine inspections before refueling, confirm that all parts are normal and effective, and set fire prohibition signs, and be safe after refueling Take precautions, avoid other vehicles during driving, and clean up if oil leaks are found.

In addition, the tank truck should be maintained regularly in daily work, the lubrication system should be cleaned in time, and various parts should be replaced and repaired. Both operators and ordinary citizens have an obligation to understand the relevant safety regulations. Because this is related to the personal and property safety of each of us, I hope you will pay attention to it.

What are the specifications for the use of sprinkler trucks?

Sprinkler trucks are one of the main equipment for sanitation machinery operations. They are mainly used for road spraying and dust suppression, improving road cleanliness and reducing the labor intensity of sanitation manual operations. In order to ensure the safety and efficiency of sprinkler operations, strict compliance with operating specifications and safe operating procedures.

Before using the sanitation sprinkler trucks, read the instruction manual carefully. Strictly following the operating requirements is an important guarantee for the use of sanitary sprinkler trucks

1. Requirements for water sources

When sanitation sprinkler trucks use ditches and ponds as water sources, please note that the end of the suction pipe does not enter the water. In order to avoid inhaling stones, a lot of sand and garbage, the end of the suction pipe is usually equipped with a filter device. It is strictly forbidden to disassemble the filter device when absorbing water. If the water source is shallow, in order to ensure that it is free of garbage and air, it is necessary to dig a deep suction point in advance. The pumps of different sanitation trucks have different requirements for the water source. The clean water pump requires no impurities in the water, and the turbid water pump requires no stones and sand in the water.

Green sprinkler truck

2. Add water diversion

Before the centrifugal pump sucks water, a certain amount of water must be added to the pump, and the water inlet must be closed after adding. When the self-priming pump is used for the first time, water needs to be added, and no water is needed afterwards.

3. The inlet pipe needs vacuum

The water supply pipe system must maintain a certain degree of vacuum when sucking water in order to suck water into the tank. The water supply pipe system must be sealed and reliable, the hose must not be damaged, and the hard pipe must not be broken. Otherwise, air leakage will occur and water cannot be absorbed.

4. Parking

Regardless of whether the sanitation sprinkler truck is before water absorption or before sprinkling, the baffle of the afterburner must be carried out when it is parked.

Sprinkler truck

5. Release water in winter

Before winter arrives, please empty the water in the pump and water pipe to avoid freezing. In northern my country, construction is usually not carried out in cold winters. After the construction is completed, the water in the pumps and water pipes is immediately discharged to prevent future troubles.

6. Precautions for sprinkling

The front sprinkler of the sanitation sprinkler truck is low, close to the ground, and the sprinkling pressure is high. The rear sprinkler truck that can be used to clean the road is high (the rear sprinkler of the sanitation sprinkler truck is usually installed on the left and right), and the sprinkling surface is wide, and it can be used for road construction. , The wider the sprinkling width of the front sprinkler should be closed, the less the amount of overlap in the middle, the more uniform the sprinkling density

7. Lubrication and tightening

During use, every lubrication point of the transmission assembly should be lubricated on time and ensure normal use.

8. Drain the dirt on time

The water storage tank of the sanitation sprinkler  truck is equipped with a sewage pipe whose inlet is the lowest point of the water tank. After a period of use, turn on the drain pipe switch on time to remove the garbage accumulated in the tank until the water becomes clean.

The above is the relevant introduction about the specifications for the use of sprinkler truck. During use, the rules must be strictly followed to ensure the safety and efficiency of the work.

How to maintain the sprinkler truck?

Sprinkler trucks, also known as greening spraying vehicles, multifunctional sprinklers, landscaping sprinklers, water tankers, water trucks, dust suppression vehicles, spraying vehicles, multifunctional dust suppression vehicles, drug spraying vehicles, pesticide spraying vehicles, and fire sprinklers . It consists of a special vehicle chassis, tank body, piping system, operating system, etc.
It has the functions of water spraying, dust pressing, high and low spraying, pesticide spraying, guardrail washing, etc. It also has the functions of water transportation, drainage, and emergency fire fighting.

It is widely used for washing all kinds of road surfaces, trees, green belts, lawn greening, roads, factories and mining enterprises construction, and high-altitude building washing.

Sprinkler truck composition

Sprinkler truck

1. Water tank assembly

The water tank assembly of the sprinkler is composed of a tank body, a supporting leg, a tank mouth and a cover, and a compartment device. The can body is usually welded by steel plates, and its cross-sectional shape can be oval, rectangular, or circular. The support legs can be divided into two types: integral chassis type and basin bottom type. The latter can be divided into separate longitudinal beams and completely independent legs. The number and diameter of the tank mouth are related to the tank body volume: according to the volume of the tank body, there can be 1-2 tank mouths; the diameter of the tank mouth is in accordance with the regulations of the Ministry of Communications “Engineering Sprinkler” (JT/T288-95) standard, It should be no less than 450mm to allow maintenance personnel to enter and exit. The standard also stipulates that the tank body must be equipped with a horizontal wave-proof plate with a volume greater than 1000L, and a compartment structure and a longitudinal wave-proof plate must also be used inside. Here, a vent hole must be provided on the lid of the tank.

2. Transmission

The transmission device of the sprinkler generally includes a reduction or speed increaser and a transmission shaft, which transmit the power to the water pump and meet the requirements of the speed and direction of the water pump. The power unit of the sprinkler can be an additional auxiliary engine or electric motor, or the main engine of the car. Generally, the power is taken from the transmission of the automobile, and the above-mentioned requirements of the water pump are met through the power take-off. If the power take-off cannot meet the above requirements, an intermediate transmission can be added. The transmission shaft can be designed and manufactured by itself according to the needs, or mature automobile-related products can be selected. Water pumps for sprinklers include centrifugal pumps and self-priming pumps.

3. Piping system

The piping system of the sprinkler has the functions of transporting water to the water tank when absorbing water, transporting the water in the water tank to the sprinkler when sprinkling water, and directing the suction water to the sprinkler. The suction pipe is generally composed of rubber hose and steel pipe, and the sprinkler pipe is usually composed of steel pipe, valve and sprinkler. There are two types of sprinklers: fixed sprinklers and movable sprinklers. The water flow direction and sprinkling density of the fixed sprinklers are fixed, and the water flow direction and sprinkling density of the movable sprinklers can be adjusted within a larger range.

4. Control system

The control system of the sprinkler includes two parts: the power take-off operation and the water absorption and sprinkler operation. There are two control modes: pneumatic control and hand control.

The pneumatic operation of the power take-off gear is composed of gear mechanism, pipelines, valves and indicating instruments.

Hand control is composed of gearshift mechanism, joystick and positioning mechanism, transmission mechanism and indicating nameplate.

There are also hand-operated operations for water absorption and sprinkling, but air-operated operations are common. Pneumatic operation includes control valves, pipelines and actuators. The control valves control the actions of the actuators to determine the direction of water flow and achieve the purpose of water absorption or sprinkling.

The working state of the sprinkler has two types: parking water absorption and driving water absorption:

Parking to absorb water. Park the sprinkler near the water source and connect the suction hose. After the centrifugal pump is filled with water, put the power take off to ensure that the pump runs at normal speed. At the same time, turn on the suction switch to pump the water into the tank. The process is:

The water source, suction pipe, water pump, distribution valve, water pipe, water tank are controlled by the control valve

The driving absorbs water. After the sprinkler arrives at the sprinkling operation point, stop, hang the parking block and the sprinkler power take-off block, and then drive at the designed sprinkling operation speed. At the same time, turn on the sprinkler switch to sprinkle the water in the tank to the place where it is needed. The process is:

Control valves control water tanks, water pipes, water pumps, distribution valves, water pipes, nozzles

Sprinkler truck maintenance

Green sprinkler truck

1. According to the application requirements of the paint, before using the new product, fill the tank with water and soak for five days and then let it go, then rinse the coating surface with water, and then fill it with water and wait for two days, then drain the water and drink it. Water out.

2. Frequently check the sealing conditions of the connection parts, switches and water suction hoses of the sprinkler water system. If leakage is found, restore or replace the seals.

3. Frequently check the fixing conditions of the water tank, pump frame, and bracket of the sprinkler. All nuts should be tightened to ensure that the connection is tight and reliable.

4. Frequently check the connection between the power take-off and the water pump. The connection should be reliable and normal operation. If oil leakage is found in the power take-off and water pump during use, the seals should be replaced.

5. There is no anti-freeze device in the waterway system of the whole vehicle. Therefore, in severe cold areas, after the temperature is below degrees Celsius, the water in the water pump, water tank and waterway system should be drained immediately. Note that the water pump plug should be closed tightly after the water is discharged to ensure Seal, otherwise it will affect the water pump suction.

6. The paint on the tank body must not be stuck with gasoline and kerosene, because this will accelerate the damage to the paint. Check the quality of the paint on the tank regularly. When the paint is damaged, touch up the paint in time to prevent corrosion of the tank.

7. For the use and maintenance of the vehicle chassis and engine parts, please refer to the manual of the truck.

8. The medium that the ball valve passes through should not be too dirty, so as not to damage the sealing ring and reduce the service life of the ring valve. Each ball valve should not be operated in a half-open state for a long time, otherwise the sealing ring will easily deform.

9. The filter screen of the inlet pump should be removed and washed frequently to prevent the scum from blocking the filter screen and affecting the flow rate.

10. Because there is a wood rubber pad between the sprinkler tank and the car beam, the U-shaped bolts will loosen due to the deformation of the wood glue after the water tank is loaded. Therefore, the U-shaped bolts must be tightened regularly after the car is heavily loaded, especially This must be done when using a new car.

How to do the maintenance and repair of concrete mixer truck?

In construction projects, concrete is an indispensable construction material, and a professional concrete mixer truck is used to transport concrete. The concrete mixer truck is equipped with a cylindrical mixing drum, which always keeps rotating during transportation to ensure that the carried concrete will not solidify. After transporting the concrete, be sure to rinse the inside of the mixing drum with water to prevent the hardened concrete from taking up space. Then, after the daily transportation is completed, how to do the maintenance and repair of the concrete mixer truck?

Cleaning

Since concrete will solidify into a hard block in a short time and is corrosive to steel and paint, it is necessary for daily maintenance to wash the concrete adhering to the concrete storage tank and the inlet and outlet after each use of the concrete storage tank. Serious work. These include:

1. Rinse the feed port with water before each filling to keep the feed port moist during filling;

2. Fill the washing water tank that comes with the car with water while loading;

3. Rinse the feed port after loading, and clean the remaining concrete near the feed port;

4. After unloading at the construction site, flush the discharge chute, and then add 30-40L of cleaning water to the concrete storage tank; keep the concrete storage tank positive and slow when the vehicle returns;

5. Remember to drain the sewage in the concrete storage tank before loading the next time;

6. At the end of the day, thoroughly clean the concrete storage tank and around the inlet and outlet to ensure that there is no cement and concrete agglomeration.

As long as these tasks are not carried out seriously once, they will bring great trouble to future work.

Maintenance

Mixer truck

1. Reasonably determine the protection period

The car protection period refers to the distance or time of car protection. In the process of practical application, car owners should refer to the protection cycle recommended by the car manufacturer, contact the car’s own skills and application conditions, and make appropriate adjustments to the protection cycle. Generally speaking, new cars are used under superior road conditions and do not need to be protected too frequently. The protection period specified by the manufacturer’s rules can be used as the upper limit; while the car’s technical condition is poor, or the use conditions are bad, the protection period should be shortened appropriately.

2. Plenty of free testing

The free inspection campaign carried out by the concrete mixer truck manufacturer is often beneficial to the owner. The owner can use these inspection activities to perform specific physical examinations on the favorite car, discover and eliminate some potential problems in real time, and then save the high maintenance that can appear in the future. Protection costs.

3. Minimize the crash repair assembly

Many concrete mixer truck owners have this feeling that after a certain assembly of the mixer truck crashed and repaired, the truck entered the maintenance period prematurely. The reason for presenting this kind of sight mainly touches on the repairers’ assembly skills and quality of accessories. Therefore, it is best to prevent the breakdown of the repair assembly, apply various advanced technical protection equipment and tricks to protect the car from disassembly, so as to prevent unnecessary damage to the car assembly and parts, improve the quality of protection, and then reduce the maintenance Total cost.

4. Do not carry too much

The maximum limit of concrete carried by the concrete mixer truck cannot exceed the maximum volume of the tank, because the density of concrete varies depending on the strength level. High-strength concrete generally has a high density. For the same volume, it will be detrimental to the vehicle if it is loaded more.

Maintenance drive

The function of the driving device is to drive the rotation of the concrete storage tank. It is composed of a power take-off, a cardan shaft, a hydraulic pump, a hydraulic motor, a control valve, a hydraulic oil tank and a cooling device. If this part stops working due to a fault, the concrete storage tank will not be able to rotate, which will cause the concrete in the vehicle to be scrapped, and even the whole tank of concrete will condense in the tank, causing the concrete mixer truck to be scrapped. Therefore, whether the driving device is reliable is an issue that must be paid attention to in use. To ensure the integrity and reliability of the drive device, the following maintenance work should be done:

1. The universal rotating part is the part with frequent failures. Grease should be added on time, and the wear condition should be checked frequently and repaired and replaced in time. The team should have a spare cardan shaft assembly to ensure that it can resume work within tens of minutes in the event of a failure.

2. Ensure that the hydraulic oil is clean. The working environment of the concrete mixer truck is harsh, and the dirty cement sand must be prevented from entering the hydraulic system. The hydraulic oil should be replaced regularly according to the requirements of the manual. Once the hydraulic oil is found to be mixed with water or sand during the inspection, it is necessary to stop the machine immediately to clean the hydraulic system and replace the hydraulic oil.

3. Ensure that the hydraulic oil cooling device is effective. It is necessary to clean the hydraulic oil radiator regularly to prevent the radiator from being blocked by cement, check whether the electric fan of the radiator is operating normally, and prevent the hydraulic oil temperature from exceeding the standard. As long as the hydraulic oil is clean, there are not many failures in the hydraulic part; however, the service life is different for different manufacturers.

Due to the large volume of the concrete mixer truck and the special cargo it carries, the daily maintenance and repair of the concrete mixer truck must be done. The concrete mixer truck should not overly bump the glass during transportation. If the road condition is not good, the tank axle of the tank truck will be damaged; grease should be applied to the rotating wheels from time to time to reduce wear and tear; The maintenance of the mixer truck itself reduces the probability of vehicle damage.

What are the safety issues for tank truck transportation?

As a mineral resource, oil plays a very important role in industrial production and people’s daily life. All countries in the world are vigorously exploiting and using oil. Petroleum must be transported by tanker trucks before it is used, but oil is very combustible and explosive, so the safety issues during transportation cannot be underestimated. So, in this process, what are the specific safety issues for tank truck transportation?

External security

Oil tank truck

1. Control combustibles

① The oil spill of the oil tank of the tanker must be prevented. The oil spills, spills, drips, leaks and spills that occur during the loading and unloading operations of oil tankers shall be promptly removed and handled.

②It is strictly forbidden to pour oil, sludge, waste oil, etc. into the sewer after the tanker unloads the cargo, and should be collected and placed in the designated place for proper disposal.

③All flammable materials should be removed near buildings such as oil tanks, warehouses, pump rooms, oil distribution rooms, and oil blending workshops.

④ Oil-stained cotton yarn, oil rags, oil gloves, oil paper, etc. used in the maintenance and maintenance of the tank truck should be placed in a covered iron drum outside the workshop and removed in time.

2. Cut off the source of fire

①It is strictly forbidden to bring matches, lighters or other types of fire into the oil depot, oil product storage area, and oil product receiving and dispatching area. Strictly control the flow of fire sources and open flame operations.

②Pyrotechnics are strictly prohibited in the oil depot. When open flames must be used for repair operations, they must be reported to the relevant departments for review and approval and safety precautions have been taken before the fire can start.

③Before cars and tractors enter the warehouse, they must wear a fire shield at the exhaust pipe, and immediately turn off the engine after parking. It is strictly forbidden to inspect and repair the vehicle in the warehouse, and it is not allowed to start the engine during operation.

④ When the railway locomotive is in the warehouse, it is necessary to attach an isolation car, close the ash box baffle, and do not clean the furnace in the warehouse area or stay in the non-operation area.

⑤The tanker said at the dock that the use of open flames is strictly prohibited. It is prohibited to carry fire sources on board.

3. Prevent electric cremation

①The various electrical equipment used in oil depots and all working places must be explosion-proof, and the installation must meet the safety requirements, and the wires must not be broken, exposed or short-circuited.

② High-voltage wires are strictly prohibited to cross over the oil depot. The distance between the oil storage area and the barreled light oil warehouse and the wires must be more than 15 times the length of the electric pole.

③The rails leading to the oil depot must be installed with insulating partitions in front of the entrance to prevent the external power supply from flowing into the oil depot from the rails and sparking.

4. Prevent metal friction

①Strictly implement the relevant regulations of the warehouse and operation area. It is forbidden to wear nail shoes or iron palm shoes to enter the oil depot, not to mention climbing oil tanks, oil tankers, tank trucks, oil tank cars and stepping on oil drums, and forbid mules, horses and iron wheels to enter the depot.

②It is not allowed to knock out the lid of the container with iron tools. When opening the vat lid and tanker lid, you should use a copper wrench or a metal wrench that will not cause sparks in collision.

③ Metal containers should avoid collision with each other in the warehouse. It is also impossible to roll oil drums without gaskets on the concrete floor.

④During the loading and unloading operations of the oil products of the tanker, the loading and unloading crane pipes should be prevented from colliding when inserting and pulling out the tanker port or tanker hatch. Wherever there is oil and gas, iron metals should not be hit.

5. Prevent oil vapor accumulation

① Repair and welding of unwashed oil drums, oil tanks, oil tanks and other storage containers is strictly prohibited. After washing the container, open the lid to ventilate before preparing for welding. If necessary, perform visual explosion first.

②The barreled light oil products stored in the warehouse should be checked frequently, and the leakage should be found to be replaced in time. The warehouses, cargo sheds and receiving and dispatching rooms for barreled light oil should maintain air flow.

③In underground and cave oil tank areas, strictly prevent oil leakage. Ventilation equipment must be installed to maintain good ventilation to avoid accumulation of oil and gas.

Internal security

1. Install explosion-proof cameras on tank trucks

Install oil tank truck professional on-board explosion-proof cameras at the rear or oil outlet or roof of the vehicle to monitor the oil tanker transporting refined oil, and connect the cameras to the alarm system. In the event of an accident, the driver can immediately sound the alarm and call the police. Deal with it in time to minimize the damage.

Tank trucks are most prone to accidents when they are traveling at night, so the on-board explosion-proof camera installed must have a good night vision function, and the road behind the vehicle can be seen clearly in the dark.

2. Tank truck drivers should pay attention to safety issues

In addition to installing an explosion-proof monitoring system, in order to effectively avoid tank truck accidents, tank truck drivers need to pay attention to the following issues when transporting refined oil:

① Fatigue driving is strictly prohibited

Driving a vehicle in a warm cabin with poor air circulation makes it easy for drivers to get tired; they often feel mentally tired, their vision gradually becomes blurred, and their thinking becomes dull, especially when driving in the afternoon or midnight, it is easy to fall asleep. Reluctant driving can cause traffic accidents occur. Avoid fatigue driving and ensure driving safety.

②Pay attention to the accumulation of static electricity

The amount of oil in the oil tank should be appropriate: too little oil in the oil tank, large shaking space during transportation, easy to generate static electricity; too much, it is easy to cause overflow to the car with a poorly sealed oil tank mouth, so the filling volume is 85 About% is appropriate. In addition, medium-speed driving should be maintained during transportation to ensure that the fuel in the tank is relatively stable, and emergency braking should be minimized. It is necessary to connect the static wire to ensure that the static wire is in contact with the ground.

③Keep away from fire

When driving a tanker truck, smoking, answering and calling mobile phones are not allowed, and you must stay away from the tinder when parking, and you must not park on the edge of the tinder, which may cause an explosion.

④Avoid high temperature of the tanker engine

Regularly check the technical condition of the vehicle. Especially in the summer when the temperature is high, check the safe parts of the vehicle, and it is strictly forbidden to drive a sick vehicle on the road. When driving a vehicle in hot weather, you should pay attention to the change of the water temperature gauge at any time, generally not exceeding 95°C.

For cargo transportation itself, drivers need to be guarded and careful in all aspects, and special attention should be paid to dangerous goods vehicles such as tank trucks. Only when these oil tanker transportation safety matters are fulfilled, the personal safety of the driver and the integrity of the tanker cargo can be guaranteed, so as to avoid unnecessary losses.
