Introduction to the working principle of Sanitation truck hydraulic transmission system

CIMC Sanitation truck

The working medium, auxiliary components, control and actuator components, and power components together form the sanitation truck hydraulic drive system, as well as a variety of valves, hydraulic motors and oil pumps.

In the actual operation of the Sanitation truck hydraulic transmission system, it mainly relies on the action of the hydraulic pump. With the function of the prime mover, the mechanical energy is transformed into the direction of the liquid pressure energy, and the energy is efficiently transmitted.

Under the transmission of internal pipelines and control valves, the components such as motors and hydraulic cylinders are used to complete the transformation of liquid pressure energy into mechanical energy, which drives the system to rotate or reciprocate linearly.

The liquid medium in the hydraulic drive system is required to perform the system control work and the transfer of energy, and the system-specific transmission path ensures its strong functionality.

From a holistic perspective, the Sanitation truck hydraulic drive system has several advantages, mainly reflected in:

(1) It has a good overload protection function, and the stepless speed regulation performance is strong;

(2) The system occupies less space and has a lighter weight. Compared with the weight of the motor, the hydraulic motor is about 15% lighter, so there is no obvious inertia, especially in emergency stop and overload conditions. Relatively small;

The main working medium of the hydraulic transmission system is oil, so the internal components rarely wear each other when working, and have certain lubrication effect, which provides guarantee for long-term reliable operation of the system, and can also adjust linear reciprocating motion and working mechanism rotation at any time. Two working states;

The system can be easily controlled, and with the support of general and standardized hydraulic components, it can be easily applied and modified, and the hydraulic motor and hydraulic pump can be flexibly connected.

What are the maintenance rules for new tank trucks?

Concrete mixer truck

Many consumers who purchase tankers for the first time have confusions about truck maintenance. It is not clear what to do with the first maintenance and which parts need to be “protected”. To this end, the tanker manufacturer introduced to you some of the new truck needs to be protected areas, it can be said that the car’s maintenance road, from the beginning of buying home.

Truck’s “skin” paint

The skin is a very important part of our daily maintenance. The same is true for the truck. Although there is no aging problem in the new truck paint surface, from the factory to the transportation to the parking lot, the car paint has already touched the air, and it is affected by the sand and sand, and timely and correct maintenance , can make the car forever young.

Maintenance method: “Bathing” for new tank trucks must not be sloppy. If improperly cleaned, it will damage the bright oil part of the outer layer, which will cause the skin of the car to be “dark and dull”. It is best to use a mild mild detergent to remove the sand and dirt from the paint surface. Some dirt is invisible to the naked eye. If it is contaminated with chemical components such as paint and gum, it must be wiped a little with a special detergent. Finally, apply protective agents to tires, bumpers, wheel eyebrows, etc. to prevent aging.

Truck’s “heart” engine

When driving a new tanker, you can keep the engine idling and hear if there is any abnormal sound or vibration. Because the problem of the operation of the car engine has been delayed for a long time, it will accelerate wear, increase fuel consumption, shorten the life, and eventually lead to overhaul.

Maintenance method: The best way to protect the “heart” of the car is to avoid emergency acceleration or deceleration during the running-in of the new car, in order to minimize the load on the engine transmission system of the car. Some serious and cautious new car owners take the initiative to send the car to repair and maintenance after driving for 1000 km. The maintenance is usually free, and many potential problems can be avoided in time, so that the good thing is two thousand. Don’t miss it.

Truck’s “eyes” headlights

The most important thing for novice drivers is that if your tanker’s “eyes” are not good, it will not only affect the comfort of driving, but also directly related to the safety of driving. Therefore, timely maintenance of exterior lighting is critical to the driver.

Maintenance methods: Usually, before getting a reminder, it is difficult for the owner to know if the headlights, taillights, turn signals or parking lights are working properly. First of all, to calibrate the direction of the headlights, in order to ensure the safety of the driver, the headlights must be able to provide good forward illumination for the vehicles; secondly, carefully check other lights, such as turn signals, license plate lighting Lights, width lights, backup lights, and brake lights.

Truck’s “foot” tire

Newly bought tankers need to be run-in, with the aim of adapting the ability of the various components of the body to adapt to the environment. The pros and cons of car running-in will have an important impact on the life, safety and economy of the car. In this process, the maintenance of the tire is very important.

Maintenance method: When the new tank trucks is running-in, the tire pressure should be normal. The abnormal tire pressure will have certain adverse effects on the new car and it is very dangerous. If you do not rely on the barometer, it is difficult for the owner to visually check the accuracy. It is necessary to go to a regular tire shop to receive the service.

Cement bulk carrier maintenance procedures

CIMC Cement Bulk Carrier

The powder material transport vehicle, also known as the cement bulk carrier or the bulk cement truck, is composed of a special automobile chassis, a bulk cement vehicle tank body, a gas pipeline system, and an automatic unloading device. It is mainly used for bulk transportation of fly ash, cement, lime powder, ore powder, granular alkali and other dry materials with particle diameter not more than 0.1mm. We are often able to see such vehicle situations in cement plants, cement warehouses and large construction sites.

For special vehicles such as cement bulk carrier, the operation and maintenance are more complicated. Many details and key links require special attention. We start today with maintenance of cement bulk carrier to learn about the elimination of common faults in cement bulk carriers.

First, cement bulk carrier maintenance and maintenance

1. Car chassis: According to the selected car chassis instruction manual.

2. Air compressor: According to the specifications of the air compressor.

3, power take-off: always pay attention to regular inspection of its lubrication, operating conditions, if there is abnormal noise should be found out the reasons for timely elimination, annual gear occlusion and wear should be checked, and can not be overspeed.

4, gas path: should always check the sealing situation, if there is leakage in time to eliminate; often check the working condition of each valve, if the failure should be repaired or replaced; safety valve to ensure that the pressure is 0.2Mpa open, and the pressure inside the tank More than 0.2Mpa.

5. Tank body: Regularly check the tank weld seam for gas leakage. If this phenomenon is found, repair welding should be carried out in time.

6. Tank gas chamber: Check the air chamber canvas frequently. If it is moisture-tight or damaged, it should be replaced in time; check whether the air chamber pressure strip is compacted. If there is air leakage, it will affect the discharge effect and should be eliminated in time.

Second, the cement bulk carrier discharge safety operation procedures

1. Before each uncovering of the feed inlet, the pressure relief valve and the intake pipe ball valve must be opened first. After the residual gas in the tank is removed, the material cover is opened to avoid accidents.

2, always pay attention to whether the pressure gauge is working properly, strictly prevent the pressure gauge from failing, overpressure, and the tank bursting leak.

3. Always check the safety valve to ensure that the pressure is reduced at 0.2Mpa, and the pressure inside the tank should not exceed 0.2Mpa.

4, often check whether the operating table is working properly, so as not to damage the air compressor and power take-off (specially refers to the powder tank bicycle).

5. Always listen to the sound of the power take-off and the air compressor. If there is abnormal noise, stop immediately to eliminate the fault.

Third, cement bulk carrier unloading steps

1. Before unloading, check whether the discharge disc valve, external air source interface, exhaust valve and two inlets are closed and tightened. If not tightened, tighten first to prevent air leakage;

2. Start the engine and change the transmission to neutral. At the same time, press the clutch pedal to completely separate the transmission from the engine.

3. Open the power take-off solenoid valve switch and slowly release the clutch pedal to make the air compressor rotate;

4. Adjust the operating handle of the operating mechanism, adjust the speed of the air compressor to about 900r/min, and stabilize it;

5. When the pressure reaches 0.18MPa, first open the auxiliary blow pipe, then open the front and rear bin discharge disc valve to start unloading, after which the air compressor pointer will stabilize a certain value;

6. When the air pressure drops to 0.04Mpa, the rear bin has been unloaded, the blow-off pipe is closed, and the disc valve is closed several times after opening and closing. Then the rear disc valve and the rear tank intake valve are closed, that is, only the front bin is unloaded. After that, the pressure will rise and stabilize to a certain value;

7. When the pressure of the barometer reaches 0MPa, when the discharge is completed, close the air compressor (close the force switch) and close the discharge disc valve.

What are the small concrete mixer truck maintenance items?

CIMC Concrete Mixer Truck

CIMC Concrete Mixer Truck

The small concrete mixer truck is a special type of vehicle that often deals with building materials such as water, stone and cement in daily work. Long-term wear and tear is particularly severe, in order not to affect its work efficiency, we need to maintain it regularly. So what do you need to pay attention to during the maintenance process? Let’s take a look together.

1. small concrete mixer truck radiator can not be contacted with acid and alkaline, corrosive substances, so as not to cause corrosion of the radiator.

2. need to use soft water to fill the inside of the radiator, if it needs to be softened, it should be filled, so as to avoid the blockage of the radiator and excessive scale.

3. use antifreeze according to the requirements, can not be used for the cheap and use inferior antifreeze.

4. When we install and repair the small mixer radiator, be careful not to touch the radiator belt and the radiator, so as not to cause the radiator to be unsealed or the heat dissipation effect is not good.

5. When the small concrete mixer truck is completely filled with water and then filled with water, first open the water discharge switch of the engine block. When there is water flowing out, close it to avoid blisters.

6. In the usual use, it is necessary to check the water level inside the tank of the mixer truck frequently. It is necessary to stop the operation of the engine. After the temperature of the body is lowered, add water, slowly open the lid of the tank, and add water. When people want to stay away from the water inlet as much as possible, in order to avoid the temperature of the steam inside is too high, causing the price of the scalding mixer.

7. In the winter or when the temperature is very low, pay attention to the water inside the water tank when the parking time is very long or indirect parking.

8. The environment for the spare small conveyor mixer radiator should be ventilated and dry.

9. Depending on the actual situation, the user should completely clean the radiator for one to three months. When cleaning, rinse with clean water along the reverse air inlet side. Regular full cleaning prevents the radiator core from being blocked by dirt, which affects heat dissipation and affects the life of the radiator.

10. The water level gauge should be cleaned once every three months or so, and the parts should be disassembled and cleaned frequently.

The above is all the precautions for the maintenance of small mixer trucks. Special care should be taken to avoid contact with acid-base and corrosive substances, to avoid clogging of radiators and excessive scale generation. The radiators are regularly maintained and the water level gauge is regularly cleaned. Wait. When using the car, we must also pay attention to maintenance, in order to increase its life and better create economic benefits for us. If you have more questions, please feel free to contact us.

What is the weight of diesel fuel per gallon

Engineering industry

The purchase of refined oil at a gas station is often calculated in terms of weight units “tons” or “kg”, but when using a fuel dispenser to sell refined oil, it is settled in units of capacity “liters”. Then the “density” (or concept of density) needs to be introduced for weight and volume conversion.

Taking diesel as an example

Diesel density and conversion of weight and volume

The density of diesel is generally between 0.83 and 0.85, which is related to the temperature and the product itself. In general, the density in oil metering is divided into standard density, apparent density, and weight density, which correspond to three temperatures, that is, (standard temperature) 20 degrees Celsius, observed temperature, and oil temperature. It is obtained by the national standard formula or by checking the product oil density table.

The measurement process of finished oil transfer is as follows:

1. Measure the oil high;

2. The volume of the oil is determined according to the oil height and the tank volume meter (height one volume);

3. Take a small amount of oil sample in the measuring cylinder and read the density and temperature at this time with a densitometer, which is the apparent density and the viewing temperature;

4. “oil temperature” in the oil sample insulation box;

5. According to the visual density and viewing temperature conversion or look up the table to obtain the standard density;

6. According to the standard density and the oil temperature, the density of the oil in the tank at the temperature inside the tank is obtained;

7. Multiply the weight by the weight and the volume.

Note: The final result of the formula or look-up table has taken into account the effects of air buoyancy. The actual mass (m) obtained.

In summary, the weight of 1000 liters of diesel is between 830 kg and 850 kg. Not a certain value. The density of GB diesel is in the range of 0.810~0.855, and the density of different models is different.

Commonly used as:

0# diesel density 0.84 kg / liter;

+10# diesel density 0.85 kg / liter;

+20# diesel density 0.87 kg / liter;

– 10# diesel density 0.84 kg / liter;

– 20# diesel density 0.83 kg / liter;

-30# diesel density 0.82 kg / liter;

A 35# diesel density of 0.82 kg / liter;

Usually the diesel density is calculated at 0.84, so that one ton of diesel is roughly equivalent to 1190 liters.

Diesel and gasoline metrics

First of all, it should be understood that the weight and volume of crude oil and refined oil are related to temperature and density. The conversion between volume and weight units must introduce a density p. The density pt of crude oil and refined oil indicates that the oil per cubic meter of volume is ton weight at a certain temperature.

The conversion relationship is:

Volume of one ton of oil = 1 / p cubic meters

The number of barrels equivalent to one ton of oil = 1 / p * 6.29 barrels (oil)

Dividing 6.29 by the density is the conversion factor formula for how much oil is equal to 1 ton of oil.

The size of this conversion factor is related to the density of the oil. The reciprocal relationship is as follows: Daqing crude oil density is 0.8602, Shengli 101 oil depot density is 0.9082, which can be obtained separately:
Daqing crude oil conversion coefficient = 6.29/0.8602 = 7.31, Shengli crude oil conversion coefficient = 6.29/0.9082 = 6.93

The calculation method for petroleum products is also the same. If the density of a certain gasoline is 0.739, the calculation result: 1 ton of gasoline is equal to 8.51 barrels; the density of a certain diesel is 0.86, and the calculation result is 1 ton of diesel equal to 7.31 barrels.

First, the oil (excerpt)

Product name Density(p) Barrel/ton
Aviation gasoline 0.701 8.97
Motor gasoline 0.725 8.67
Aviation kerosene 0.775 8.12
Light diesel oil 0.825 7.62

Second, crude oil (excerpt)

Product name Density(p) Barrel/ton
Daqing mixed crude oil 0.8602 7.31
Victory crude oil 0.9082 6.93

Third, the volume unit conversion table

Rise(L) Cubic meter(m3) Gallon (US) Gallon (English) Barrel (oil)
158.98 0.15898 42 34.973 1
1 0.001 0.26418 0.21998 6.29*0.001
1000 1 264.18 219.98 6.29

1 cubic meter = 6.29 barrels (oil)

How many liters is one ton of diesel oil? How many kilograms is one liter of diesel oil?

Generally, the density of national standard diesel oil ranges from 0.810 to 0.855, and the density of different models is different. Such as: O# diesel 0.84 density, +10# diesel 0.85 density, +20# diesel 0.87 density, -10# diesel 0.84 density, -20# diesel density 0.83, -30# diesel density 0.82, -35# diesel density 0.82. According to the above data and calculation method, the density of one ton of light diesel oil is 0.825, which is equivalent to about 1211 liters:

1 ton = 1 * 6.29/p = 6.29/0.8257.62 barrel

1 barrel = 158.98 liters

7.62*158.98-1211.4276 liters

By analogy, one ton of light diesel oil is equal to about 1211 liters, and in turn, one liter of light diesel oil = 1/1211 tons ≈ 0.825 kg = 1.65 jin.

How many liters of gasoline is equal to one ton? How many kilograms is one liter of gasoline?

Gasoline is divided into three grades of 90, 93 and 97 according to the research octane number. For a specific temperature, the average density of gasoline is as follows:

The average density of No. 90 gasoline is 0.72kg/L;

The average density of 93# gasoline is 0.725kg/L;

The average density of No. 97 gasoline is 0.737kg/L;

The density of the product oil for general tank trucks are 0.725kg / L, and one ton of product gasoline is about 1378 liters.

1 ton = 8.67 barrels

1 barrel = 158.98 liters

8.67*158.98= 1378.3566 liters.

In general:

One liter of gasoline 90# is 1.44 g, one liter of gasoline 93# is 1.45 g, and one liter of gasoline 97# is 1.474 g.

What should I pay attention to when driving a concrete mixer truck?

CIMC Concrete Mixer Truck

The concrete mixer truck consists of an electric motor and a rotating tank for mixing concrete-forming materials. The crank wheel is used to tilt the tank to various positions according to the requirements of the work at hand. There are a lot of things to be aware of during the concrete mixer truck driving. Then let me know what you need to pay attention to when driving the concrete mixer truck. I hope to help you.

First, it is slow to move

1. The time of turning must be slow

The mixing truck has a high center of gravity and is easy to roll over! Slow down and downshift before entering the corner, try not to brake when you turn. At any time, after the rearview mirror, check to see if the can is turning, the speed is as slow as possible, the speed is too high, and the vehicle simply swings.

The section with a large angle of inclination stops the tank, and when it is full of material, it goes to the section where the skew point is large, and the tank is stopped first. The original center of gravity of the mixer is high, and stopping the rolling of the tank is conducive to maintaining the stability of the vehicle.

2. The bad road is suitable for low speed gear

In case of uneven road surface, the pits are smashed with appropriate low-speed gears to ensure that the car is explosive at any time. Wooden boards, sharp stones must be avoided, especially heavy cars!

3. The uphill is best to reduce the file early

If you are full, pay attention to the steep start, pay more attention to the uphill, not to reduce the file, it is best to reduce the file early. And the maximum speed of the accelerator is accelerated, and the concrete is prevented from flowing out.

4. Do not go downhill in heavy traffic

Long-term travel may be a test of the brakes before going downhill. Do not skid downhill in heavy traffic, slow down early when turning downhill, then reduce gear and then slow down, with the best brake function.

5. Must pay attention to the issue of height limit

The road conditions on the construction site are messy, so be careful of trees, etc., especially to avoid scratching the wires.

Second, enter the construction site to check more

1. Walk as far as possible when entering the construction site

The construction site is simple, the roadbed is soft, and now the mixer truck is more than 20 square meters. It is close to the road, and the road is simply crushed and collapsed, causing the vehicle to roll over.

2. Get off early to check the reverse line

Most of the mixer trucks work at night. After arriving at the construction site, it is best to get off the vehicle and take the flashlight to check the reverse road. There are obstacles, there may be pits that may be relatively soft, and they must be remembered and timely arranged in the steel nails.

3. The time of reversing must be slow

Don’t always stick your head out of the window. You have to look at the two rearview mirrors together. If you are really uncertain, you will see the parking and see it again. Many roads are softer than the excavator, and the car is simply stuck.

Start with a gear (this time can stop the can, the tank will turn very fast when the throttle is large, the car will be more unstable), slowly and evenly travel, the reverse road is as straight as possible, if you want to repeat the reversing, Don’t kill or beat the steering wheel. Simply turn off the fire on the soft road. When the throttle is poured out, the speed is too fast and it hits something.

Third, can not be careless when unloading

1. Allow the mixing tank to work at full speed for one or two minutes before unloading

Allow the concrete to mix well, add some water if necessary, make the concrete mix more evenly, and facilitate the discharge.

2. Wet the hopper chute before discharging

When discharging the car, try to stop the car on the flat ground and drain the hopper chute before discharging.

3. Do not carelessly unloading and discharging workers to make good contact

It is best to look at it when you put it out, so as to avoid the unloading operation of the discharging operation lever. It is best to stop the tank when it is rotating the center position, and maintain the reducer and the supporting wheel.

Make good contact with the discharge workers, don’t sleep too much when unloading. If the workers are upset, put your car on the construction site and don’t turn the cans, it will be troublesome to form a stuffy can.

4. The mixing tank must be carefully washed clean

When washing the jar, it must be carefully washed and cleaned, and the water should be repeatedly rotated twice, and then released. When the water is finally discharged, put the water in the tank into the jar, and then return to the station to add water to completely clean the jar.

Sanitation truck common problems and solutions

CIMC Sanitation truck

As a high-end sanitation garbage truck, the compressed sanitation truck has close cooperation with the various operating systems, requires good sealing performance, smooth hydraulic oil circuit control system, and accurate and efficient electronic control operation. Users will inevitably encounter some problems during the use of garbage trucks. As the workload increases over time, there will be more or less problems in the car. Is there any way to quickly encounter these common problems? Effective solution, it is very important to fix these problems with the least cost. The following is a detailed explanation of common problems and solutions for compressed sanitation vehicles for everyone.

First, the operation noise is large

Poor sound insulation and high noise levels are common problems in domestic compressed garbage trucks, which often cause problems for street residents. In the design and manufacture of compressed garbage trucks, the vehicle chassis, engine and power take-off are selected to be less noisy, and measures to enhance the stability of the system movement are adopted to reduce noise, and materials that absorb noise are used, and the structural design reduces vibration: through the hydraulic system. And the optimization design of the loading mechanism improves the machining accuracy and assembly quality to achieve the purpose of reducing vehicle noise.

Second, poor sealing reliability

Since the domestic garbage has the characteristics of a solid-liquid mixture, in order to realize no garbage leakage during the garbage collection and transportation process, no odor is diffused, and the following methods can be solved.

(1) Install an edge baffle between the filler flipper and the loader to prevent waste.

(2) The floor of the compartment should have a certain slope to prevent the leakage of landfill leachate.

(3) Install a sewage tank in the lower part of the stuffer to store the dripping water between the car and the stuffer.

(3) Strengthen the seal at the joint between the loader and the carriage to prevent leakage of waste during the compression process and dripping of the landfill leachate.

Third, the rated load mass utilization rate is low

Reduce the weight of compressed garbage trucks, increase their load utilization, and reduce vehicle operating costs. Because the compression garbage truck has a complicated structure and a large self-quality, the vehicle chassis should be designed with high technical content, good power, light weight and high cost performance.

Fourth, operating comfort

In order to improve the maneuverability, the mechanical control is electronically controlled, and the electronic operation monitoring system is equipped, which is beneficial to improve the accuracy of the operation, ensure the safety of the operation, and reduce the labor intensity of the driving operator.

How to effectively prevent oil tank truck oil leakage?

Oil-tank-truck

In the use of oil tank trucks, oil leakage faults often occur, which will directly affect the technical performance of tank trucks, resulting in waste of lubricating oil and fuel, consuming power, affecting the cleanliness of the vehicle and causing environmental pollution. Due to oil leakage and reduced internal lubricating oil, the parts are poorly lubricated and insufficiently cooled, which may cause early damage to the parts and even cause accidents.

First, the reason for oil tanker oil leakage

1. After the long-term use of the sealing material, the wear is too limited, and the aging deteriorates and the deformation fails.

2. Too much oil is added, the oil level is too high or the wrong oil is added.

3. The joint surface of the component is flexed and deformed, and the casing is damaged, so that the lubricating oil seeps out.

4. After the vent plug and the one-way valve are blocked, due to the difference of the air pressure inside and outside the casing, oil leakage may occur in the weak seal.

Second, prevent vehicle oil spill measures

1. Pay attention to the role of the pad. The gasket between the components of the tanker’s rest position acts as a leakproof seal. If the material, production quality and installation do not meet the technical specifications, it will not be able to seal and prevent leakage, and even accidents. For example, the oil pan or the valve cover is not easy to compact due to the large contact area, thereby causing oil leakage.

2. All kinds of fastening nuts on the tanker truck should be tightened according to the specified torque. If the loose pressure is not tight, the gasket will leak; too tight will cause the metal around the screw hole to bulge or cause the oil to leak. In addition, if the oil pan screw plug of the oil pan is not tightened or loosened, it is easy to cause oil loss, and then the machine damage accident of “burning the tile and holding the shaft” occurs.

3. Replace the failed oil seal in time. Many moving parts on the tanker will be improperly installed, the journal and the oil seal edge will be different, and the oil will be deflected. Some oil seals use too long to lose their elasticity due to rubber aging. It is found that the leakage should be updated in time.

4. Avoid blocking the check valve and vent valve. As a result, the temperature inside the casing rises, the oil and gas fills the entire space, and the discharge does not go out, so that the pressure inside the casing increases, the consumption of the lubricating oil increases, and the replacement cycle is shortened. After the engine ventilation system is blocked, the resistance of the piston is increased to increase the fuel consumption. Due to the difference of the air pressure inside and outside the casing, oil leakage is often caused in the weak seal. Therefore, it is necessary to carry out regular inspection, dredging and cleaning of the tank truck.

5. Properly solve all kinds of oil pipe joint seals. The coupling nut of the vehicle is often disassembled and assembled, and it is easy to loosen the buckle and loosen, which may cause oil leakage. Replace the union nut, solve the cone seal with the grinding method, and tighten the nut to solve the seal.

6. To avoid the wheel hub oil. Excessive grease in the hub bearing and the cavity, or its oil package is not properly matched, the quality is poor and the aging is invalid; the temperature of the hub caused by frequent braking is too high; the looseness of the axle nut can cause the hub to simmer. Therefore, use the “cavity lubrication method” to clear the vent hole.

What should I pay attention to when driving a tanker safely in summer?

Water tank truck

Since entering the summer, the temperature has gradually increased, and traffic accidents have begun to rise. Why are summer traffic accidents more than the other three seasons? What are the safety issues for tank truck drivers to drive in the summer?

In summer, the psychology and physiology of the tank truck driver will be different from other seasons. The hot weather, a lot of physical exertion and strong sunlight will cause the driver’s working conditions to deteriorate. High temperature weather makes people prone to irritability. In the closed environment of the compartment, once people are irritated, it will lead to inattention when driving, and it is difficult to avoid when encountering dangerous situations. At the same time, the summer is long and the night is short, and the temperature is high. Many drivers have insufficient rest, resulting in insufficient energy, fatigue and drowsiness in driving. This situation will make the tank truck driver unresponsive to emergencies, thus Lead to traffic accidents.

So, how to ensure that the tank truck driver has a good mental and physical state in the summer? The method is very simple. First of all, it is necessary to maintain sufficient sleep time. If there is mental fatigue and unresponsiveness during driving, stop immediately and wait until the mind is awake before continuing to drive. Secondly, if you find that you have a bad mental state such as anxiety, it is best to find a quiet place for deep breathing adjustment and try to avoid driving.

In addition, we need to pay attention to some details to better ensure the safety of tank trucks.

(1) Always check tire pressure

As the temperature and the temperature of the road surface gradually increase, the high-speed or long-distance travel, the tire pressure is easy to rise, causing a puncture. For safety, please stop and depress frequently.

(2) Be careful when driving

In the hot weather, people like to wear umbrellas, and in order to cover the sun, the height of the umbrella is generally low, blocking the line of sight of the umbrella holder. Therefore, drivers must be extra careful when driving, especially when overtaking and turning.

(3) Never wear slippers to drive

In summer, drivers and friends like to wear slippers, which are both good-looking and cool, and some even drive in slippers.
In fact, this kind of practice is very dangerous. In the event of an emergency, if the slippers do not follow the foot when stepping on the gas pedal or braking, it is very likely that the brake timing will be delayed, resulting in a traffic accident.

(4) It is not advisable to use a gas lighter

In the midsummer, the heat wave is rolling, and some drivers have the habit of smoking and getting rid of it. After igniting the cigarette, the gas lighter is usually placed on the instrument panel. This is very dangerous. A disposable gas lighter that holds a liquid gas in a plastic container that expands when heated above 40 degrees Celsius. The plastic case will explode due to heat. Although the gas lighter’s explosion power is not great, when the car and some oil, flammable materials, etc. are put together, once an explosion occurs, it is easy to cause a fire, and the consequences are unimaginable. Therefore, in the hot summer, drivers should not use gas lighters, and smoking is not allowed when driving.

(5) It is not appropriate to open the air conditioner

When the engine is running at an idle speed, the gasoline is not completely burned, and carbon monoxide is generated. Generally, vehicles equipped with air conditioners have better sealing performance. Most people will feel dizzy and tired when they stay in this environment for a few hours, and their memory will diminish. At the same time, the people in the car exhaled a lot of carbon dioxide, which drastically reduced the oxygen in the car. Therefore, the air conditioner should be properly adjusted, or the window should be opened at intervals.

(6) It is not advisable to wear sunglasses that are too dark

The dark color of the sunglasses can delay the time the eye sends the image to the brain. This visual delay causes the speed perception to be distorted, causing the driver wearing the sunglasses to make a wrong judgment. Studies have shown that dark-colored sunglasses will extend the driver’s response time to an emergency by 100 milliseconds, increasing the braking distance of 2.2 meters.

(7) Avoid fatigue driving

The summer temperature is high, and the physical exertion is large, especially at noon, which is easy to fatigue and doze off. Therefore, keep enough sleep time to ensure full energy. If you feel sleepy in driving, you should stop in time, take a proper rest for a while, and continue driving after you are clear-headed. In addition, the hot weather can also cause mood irritability, should always keep calm and observe the traffic rules.

(8) Beware of spontaneous combustion

Several auto-ignition accidents occur every summer. Therefore, before going out, be sure to check whether the high and low voltage lines of the vehicle are short-circuited or aging, whether the plug is loose, whether the battery is in normal working condition, and whether there is oil leakage in the oil circuit. In addition, flammable and explosive materials such as gas lighters should also be cleaned up in time. It is necessary to equip the car with a fire extinguisher and be proficient in the operation to prevent accidents.
