Detailed explanation of tanker structure performance

A tanker is a tank-shaped transportation vehicle used to transport various liquids, liquefied gases and powdered goods, including gasoline, crude oil, various viscous oils, vegetable oils, liquid ammonia, alcohol, water, and various acids. Alkali liquids, cement lead oxide powder, etc., tank trucks occupy a very important position in transportation, accounting for about 18% of the total number of trucks.


According to the mode of transportation, tank cars can be divided into two categories: railway tank cars and road tank cars.
Road transportation tankers can be divided into oil tankers, steam tankers, liquid tankers, cement bulk carrier, cement mixing tankers, and fuel tankers according to their uses.

Tanker structure

Although there are many types of tanker trucks, they all have an overall bearing structure. The body of most tankers is composed of two parts: the tank body and the underframe.

tank truck

Tanker tank body introduction

The tank body of the tanker is a horizontal cylinder structure, and the cylinder part is welded by the upper plate, the bottom plate and the end plate. The upper plate is made of 9mm thick steel plate rolled into road tank models. The bottom plate is made of 11mm thick steel plate due to greater force. The bottom plate accounts for about 1/4 of the circumference of the full cylinder. The end plate thickness is 11mm steel plate. Press into a spherical convex panel with a transitional arc part.

Generally, the spherical radius of the tank end plate is about 3500mm, and the transition radius is 100mm. When the tank plate is made of ordinary low-alloy steel, the thickness of the steel plate is correspondingly 8mm and 10mm. The diameter of the tank increases with the increase in volume. The inner diameter of a tank with a volume of 30 cubic meters is 2100 mm; a tank with a volume of 50 cubic meters is 2600 mm; and a tank with a volume of 60 cubic meters is 2800 mm.

However, due to the existence of the air bag, the manufacturing process is more complicated, and it is not convenient to clean the tank body. In addition, practice has proved that when the liquid is not full, the impact on the end plate of the tank is not so significant, so the air bag is eliminated in the tank trucks now produced. In order to ensure that the total volume of the tank remains unchanged, the length of the tank is lengthened to make up for this part of the volume of the air bag.

At this time, there is a ruler in the tank to limit the amount of oil carried, leaving an empty volume for liquid expansion, and avoiding overflow when the liquid expands.

Tanker chassis

Because the tank itself has great rigidity, the weight of the liquid in the tank is mainly borne by the tank body, and then transmitted to the steering tank frame through the bracket and bolster, so the tank frame mainly bears the horizontal longitudinal traction impact. The center beam is generally made of two channel steels. The central part is covered with an upper cover plate with a thickness of 8 mm. The cover plate is welded with a tank body lower saddle plate. The center of the cover plate is provided with an oil trap hole or an oil drain valve hole. There are drainage pipe holes at both ends (when there is a heating jacket), and a reinforced lower cover plate is welded on the part of the center beam near the core plate. The corbel generally uses a box-shaped section, on which a tank bracket is mounted, which is composed of a web-shaped plate and a skid. The web-shaped plate is riveted or welded to the steel plate of the corbel to be molded and welded to form a groove shape. On the end beams and corbels, so that the tank body is supported on it by skids. The end beams are molded and welded into a trough shape from steel plates with a thickness of 6 mm. There are side beams between the end beams and the corbels, which are mainly used to enhance the rigidity of the ends and transfer part of the longitudinal force to the corbels. In addition, the underframe is also equipped with railings, walking boards, handrails, and pedals.

Bottomless tanker

Since the tank body of the tanker is an integral cylindrical structure with greater strength and rigidity, the tank body can not only bear the weight of the liquid, but also the tanker can bear the longitudinal force acting on the tanker without the need for an underframe. There are no middle beams, side beams and cross beams between the two corbels. The tank body is welded to the traction beam and the corbel beams. The connection device between the tank body and the underframe is eliminated, and there is no need for jamming. The tank car has its own weight and can give full play to the load-bearing role of the tank metal material.

The difference between the tank body of the tank car without a chassis and the tank body of the tank car with a chassis is the supporting part at both ends. The traction beam and the corbel beam of the tank car without a chassis are connected with the tank body by welding to transmit the longitudinal force.

Summary of concrete mixer truck models

The concrete mixer truck model has 3 cubic meters, 3.5 cubic meters, 4 cubic meters, 5 cubic meters, 6 cubic meters, 8 cubic meters, 9 cubic meters, 10 cubic meters, 12 cubic meters, 14 cubic meters, 16 cubic meters and other specifications. The meaning of each model is different, which is mainly reflected in the difference in loading. Therefore, when choosing a concrete mixer truck model, the loading capacity is mainly considered.

Under normal circumstances, an 8 cubic concrete mixer truck can hold 8.5-9 cubic meters of concrete, and a 10-cubic tank truck can hold 10.5-11 cubic meters of concrete. Concrete mixer truck manufacturers (such as CIMC Linyu) will keep it in the design. Lower the margin to prevent the concrete mixer truck from sprinkling materials on steep slopes. Therefore, the volume indicated on the concrete mixer truck means that it can load the volume of concrete.

Dongfeng concrete mixer truck

Determining the actual loading capacity of the concrete mixer truck can be determined in this way:

1. Weighing. If there is a contract, there is this item. It is best to draw the truck and weigh it. Don’t tell the concrete mixing station in advance. When the truck comes, you will say that you want to weigh the truck and let them come witness. After weighing the gross weight, come back and unload the concrete and then remove the tare weight. You can get the total weight of the concrete on the truck. You know from the report of the mixing station the bulk density of each cubic meter of concrete (such as 2380kg/m3). You can use this total The weight is divided by the weight per square meter to know the volume. Usually, the error in the coagulation of the regular mixing station cannot exceed 2%.

2. Measuring the square. That is, the template you have made is convenient for accounting, and the calculated square quantity is compared with the actual discharge square quantity.

Theoretically, the greater the load of transport vehicles, the higher the transport efficiency, but this will also lead to a linear increase in vehicle purchase costs and a decline in trafficability. The loading capacity is 8~9m. The concrete mixer truck with an 8X4 chassis has a load capacity of 6~7m. The price of the 6X4 chassis is 309/5~40% expensive. At the same time, the construction site is generally narrow and the temporary construction road conditions are very poor. The inconvenience of large vehicles, especially semi-trailers, must be fully considered. Therefore, when determining the loading capacity of a vehicle, various factors must be considered comprehensively, and one must not lose sight of the other.

Looking at the market, concrete mixer trucks with 6~7m 6X4 chassis have the highest cost-performance ratio, followed by semi-trailers with 10~12m loading capacity, and 8X4 chassis with 8~10m 8X4 chassis have the lowest cost-performance ratio. Therefore, 6~7m concrete mixer trucks are generally used.

In addition, in order to meet the needs of individual large-scale projects, a small amount of 10~12m semi-trailers can be appropriately equipped. This can take into account various needs and is a more reasonable configuration. If funds are sufficient, repairs, accessories and after-sales service can be guaranteed, purchasing imported products from famous brand manufacturers is a good choice.

How to deal with the rust inside the tank of a sanitation garbage truck

The garbage truck in the sanitation truck series is the most utilized model, and you can see the garbage trucks busy all year round. In daily use, the driver may neglect its maintenance, causing some minor defects in the parts of the garbage truck. Garbage truck is a special vehicle for greening. The water tank can easily produce rust in the long-term water quality. How to deal with the rust inside the tank in the simplest way?

Method for removing rust from multifunctional sanitation garbage truck

Flushing sweeper truck

1. Use high-pressure water to remove rust

Use an ultra-high pressure water scrubber to remove rust on the inner wall of the sanitation garbage truck water tank, and then rinse with water after a few minutes. This method can remove all kinds of chemical impurities on the gap of the tank wall, so that the original steel plate body is not damaged. All the hidden dangers of pitting and pit corrosion can be found on the washed tank wall, which effectively guarantees the quality level of the rust removal of the water tank of the sanitation garbage truck. This method quickly soaks and peels, decomposes the buildup of scale, rust and other mineral buildup, effectively restrains the corrosion of steel, copper and other metals, and has no effect on most painted surfaces. Non-concentrated hydrochloric acid and concentrated sulfuric acid are dangerous and pungent, use insurance, and have high rust removal efficiency.

2. Sandblasting and rust removal in the water tank

In addition to the high-pressure rust removal method, there is also sandblasting and rust removal. This method is also a common method used in domestic sanitation garbage truck water tank rust removal. Sandblasting and rust removal require the use of mechanical equipment. This rust removal method has good results and high quality, and can completely remove and clean the rust spots inside the tank. After rust removal, a large amount of dust will contaminate the environment, which is also a major problem.

3. The reincarnation washing method in the tank

If it is a small-tonnage sanitation garbage truck, such as a 5-ton sanitation garbage truck, 10-30% of the total capacity of the sanitation garbage truck’s water tank should be injected with a special paint remover (composed of dichloromethane and ethyl acetate) to impregnate and swell. The old coating is peeled from the tank wall, soak for about 30 minutes, and then cycle continuously for about 2 hours. Pay attention to the pH value to maintain at 1.5±0.2.

Compression docking garbage truck

Sanitation garbage trucks are also called multifunctional greening and sanitation garbage trucks. It is used for cleaning road surfaces, sanitation, dust prevention, watering, spraying pesticides, etc. in urban roads, large factories, troops, gardens and other units to achieve the effect of beautifying the environment. Then use the cleaning liquid, and then use the water purification wheel to recycle the water tank of the small sanitation garbage truck, and then use the rust remover (mainly hydrochloric acid, corrosion inhibitor, etc.) for pickling time for 15 minutes. Passivation is required for at least 4 hours after rust removal, and finally the paint is refreshed in the tank.

Finally, we must remind all car owners that they must pay attention to their own safety when derusting the tank body of the sanitation garbage truck. When using chemicals to remove rust from the water tank, never let your body come into contact with the chemicals.

Look for these four points when choosing a concrete mixer truck

Concrete mixer truck

Speaking of concrete mixer trucks, all drivers and friends must be very familiar. With the hot market, concrete mixer trucks are becoming more and more popular with customers. But do you know how to choose a suitable concrete mixer among the numerous mixer truck markets? Today, concrete mixer truck manufacturers will share how to choose a mixer truck that satisfies you in four steps.

Choosing a big brand is more secure

Brand is the guarantee of quality. Although the same chassis and tank body, big brands may be much more expensive than some small manufacturers. But when buying a concrete mixer truck, you must not only consider the cost, but also the quality and service. I don’t want to think about whether the products I buy cheaply are of poor quality?

Concrete mixer truck

The reason to buy a large-brand concrete mixer is first of all because of the mature technology. Big brands usually have perfect quality control to ensure product quality. Secondly, big brands have incomparable advantages over small brands in terms of production technology, materials and stability. Third, big brands pay more attention to word-of-mouth to shape their corporate image, and there is no such thing as cutting corners. Finally, the after-sales service of big brands will be better. The working environment of mixer trucks is usually harsh, and various minor faults are inevitable. A comprehensive after-sales service network can help you save money and effort in maintenance.

Chassis selection

The chassis of the mixer truck can cope with various road conditions, is not easy to cause problems, daily driving is stress-free, the engine must be stable and powerful, the overall performance of the vehicle must be good, and it is best to save fuel… Most drivers will ask when choosing a chassis these questions. As for how to choose, it is recommended to be brand-oriented. Ensure that the chassis of the mixer truck can provide sufficient power for the hydraulic system on the top.

Concrete mixer truck

When it comes to the chassis, you have to mention the three major components of the chassis: engine, transmission, and axle. Does the engine have strong power, geometric emission standards, and fuel consumption? How about the fuel-saving performance of the transmission in several gears? There are multiple front axles and multiple rear axles in the axles. What is the bearing capacity? We need to ask carefully when purchasing.

Regarding whether the chassis should be imported or domestically produced, everyone needs to weigh the pros and cons. In general:

The imported chassis is really good. The mainstream Isuzu Nissan Diesel and Hino Mitsubishi can see it. The advantage is that it has less maintenance, convenient operation and low fuel consumption, but the price is very troublesome, and the square quantity is generally small. Two major treasures of domestic brands, convenient maintenance and good price, quality is gradually surpassing, and you can choose any quantity, economical and cost-effective.

Hydraulic system

In the hydraulic system, the most important are oil pumps and motors. The mixer truck is often under high load, so the stability of its entire hydraulic system is very high. Stopping the mixing tank may cause the concrete in the tank to solidify. Therefore, the hydraulic system must not be careless.

Commonly used imported and domestic hydraulic systems:

Hydraulic system

When buying a mixer truck, you must ask clearly what brand of hydraulic oil pump, motor and reducer are used, and what is the status of these brands in the industry.

Mixing tank

Mixing tank

For agitated tanks, wear resistance is the first priority. The material and production process used for the tank directly affects whether the quality mark is guaranteed. The mixing tank is generally made of high-strength wear-resistant steel. It must be noted that some brands will make a fuss about the thickness of the steel plate. At the same time, pay attention to whether the blades in the mixing tank are also made of high-strength wear-resistant alloy.

Second, whether the design and configuration are reasonable is also crucial. Whether the concrete mixer truck meets the domestic transportation and road conditions, and whether the configuration can effectively improve the convenience and safety of the vehicle use must be comprehensively considered.

Concrete mixer truck

Third, lightweight has become an industry trend. Lightweight design can greatly increase the loading capacity and bring higher operational value to users.

Finally, the level of the tank car manufacturing process affects the service life of the stirred tank. The processes including the weld strength, the quality of the parts and the coating quality are all important criteria for evaluating the stirred tank. And how to ensure the accuracy of manufacturing and the consistency of products, you need to settle on whether to have a large-scale digital and intelligent production line.

When buying a car, don’t be greedy for small bargains. You should have a sufficient understanding of the mixer brand. It is not just a price comparison. If necessary, a visit to the factory may help you gain more.

Summary of common failures of mixer trucks

I believe that for a veteran driver with many years of truck experience, some simple faults in the car can be dealt with only by moving his fingers. But there are also some drivers who encounter problems when they encounter problems with the mixer, and they will inevitably be taken advantage of by entering the factory for maintenance. Today, Mixer Common has compiled a super practical checklist of common failures of mixer trucks, and there is always one that can come in handy.

The overall analysis of tank truck capacity verification method

With the increase of automobile users and the expansion of the amount of oil used, in order to meet the needs of market supply and transportation, large-tonnage and large-volume oil tank trucks have emerged. For a long time, in the shipment and measurement of light oil products, the tank truck after verification is an important measuring instrument in oil product settlement and trade settlement. From the delivery of the upper-level oil depot to the verification of the intermediate tanker truck, and then to the inspection and acceptance of the lower-level gas station, in this series of processes, the petrochemical department is constantly strengthening the measurement management mode of the promotion of the sales of the lower-level gas station. Determining that the volume error of oil depot shipments is within +0.3%, and how to calculate the loss in tank truck transportation? The objective existence of these problems has made the measurement and verification of tank trucks more and more important.

First, the definition of the capacity comparison method

The capacity comparison method is the most widely used verification method in capacity measurement. At present, there are first-class standard metal gauges with high accuracy, so the capacity comparison method can be used not only for the verification of working gauges, but also for the verification of standard gauges at all levels. Its measurement process is as follows: fill the standard meter with water to a certain volume scale line, and after the liquid level is stably reading, pour all of it into the verified working meter. After the liquid level is stable, read the marking line capacity value of the working gauge. Compare and analyze the respective display values ​​of the standard gauge and the working gauge, you can get the verification result. For example, how big is the error of the working gauge and whether it is qualified? If the working gauge has no graduation line, then its stable liquid level position is The capacity value of the standard gauge is at the scale position on the working gauge, which is the capacity value calibration.

The law has the following characteristics:

(1) Simple operation, rapid verification and high work efficiency;

(2) The environmental conditions are not high, and indoors at room temperature are sufficient;

(3) It has high verification accuracy.

tank truck

Second, preparations before testing

Generally speaking, the detection environment of the capacity comparison method is fixed. There must be a high platform for placing standard metal gauges. There must be enough water source on the high platform. The testing field under the high platform must be solid and flat, so that the tanker can be parked steadily. . Therefore, some advance preparations must be made when checking the capacity of the tanker truck. Such as:

(1) Determine whether the high platform, water source and testing site of the testing station are complete and qualified;

(2) Park the oil tanker under a high platform, and prepare a water pipe between the standard metal gauge and the oil tanker;

(3) Connect the water outlet of the standard metal gauge with the prepared water pipe, the inlet of the water pipe is connected to the water outlet of the standard metal gauge, and the outlet of the water pipe is placed at the oil inlet of the tanker;

(4) Prepare the commonly used measuring tools, such as dipstick or T-square, thermometer, stopwatch, 1000ml graduated cylinder, steel ruler, tire pressure gauge and protective equipment.

Third, the measurement of basic data in testing

The large number of measurement tools used when verifying the tank truck capacity will inevitably generate a large amount of measurement data, so it is necessary to measure step by step and properly keep the quantity.

(1) Determine the position of the lower gauge point and measure the total height of the lower gauge point with a dipstick;

(2) Use a dipstick to detect the height of water in the oil tank and use a steel ruler to detect the outer height of the oil inlet;

(3) Use a thermometer to measure the storage water temperature and ambient temperature;

(4) Use a tire pressure gauge to measure the air pressure of each tire of the tanker;

(5) At the time of verification, use a stopwatch to calculate the titration time to wait after water is injected into the tanker;

(6) According to the nominal capacity of the tanker, calculate and record the 75% capacity value.

From the measurement of these overall basic data, a unified, specific and detailed application of the various capacities of the automobile tank truck is formed, and the basic data is completed in various aspects such as the calculation of external high values, water storage temperature, and capacity values, to provide further refinement. Thick technical data.

tank truck

Fourth, the verification of the capacity value in the test

The verification of the capacity value is divided into two parts, one is the verification of the nominal capacity of 75% with the content value; the other is the verification of the content value in the range of 75% to 100% of the nominal capacity. When verifying 75% of the content value, it is necessary to select a standard metal meter to inject 75% of the nominal capacity of water into the tank truck according to its use requirements; when verifying within this nominal capacity, every time water is injected, It is necessary to read the water surface height and water temperature of the glass tube of the standard metal measure, and record it in detail for verification; when the water in the oil tank reaches 75% of the nominal capacity, wait for the water temperature and wall temperature in the oil tank to balance, then measure And record the water surface height and water temperature in the oil tank.

When the water level in the oil tank is stable, use a special T-square to measure the height of the liquid level. The height measurement should be carried out twice. When the difference between the two readings is greater than 1mm, the measurement should be repeated. The arithmetic average value is the height corresponding to the capacity of the point. If the tanker has dual oil inlets, the liquid level should be measured separately, and the average value of the measurement should be taken as the air height of the capacity at that point. The operating procedure is roughly the same when verifying the value in the range of 75% to 100%. No less than 10 verification points within the range of 75% to 100% of the nominal capacity of the oil tank with a nominal capacity of 10000L or less (including 10000L) shall not be less than 12 verification points with a nominal capacity of the oil tank above 10000L. Record the water temperature of the standard gauge and the tank truck for each measurement.

tank truck

After the tank volume measurement is completed, the bottom-mounted pipeline can be measured. The pipeline volume measurement can be done by putting water in the pipe and then putting the water in the pipe into a measuring cylinder for measurement. Open the drain valve to drain the water, observe that the drain port is in a drip state, and close the valve after 3 minutes. The above is the first verification. For newly manufactured and repaired oil tanks, the capacity value verification shall be carried out no less than twice. The difference between the high value of the second-pass verification and the first-pass verification should not be greater than 1mm, otherwise the test should be repeated. The subsequent verification can be performed once. Generally speaking, after all data measurement is completed, strict data processing is required. At the same time, in order to understand the measured capacity data intuitively, piecewise linear interpolation can be used to compile a detailed capacity table.

Fifth, summary

The capacity verification of automobile tank trucks is a technical and comprehensive process. It needs to consider many factors. The rapid, efficient and accurate measurement of the capacity of automobile tank trucks is an important research topic. Handover, cost accounting, ensuring trade fairness, and energy measurement management are of great significance. Therefore, through the understanding of the definition of the capacity comparison method, some work preparations are made in the actual verification process, and the basic data and the approved capacity value are accurately measured. These are very important for the overall analysis of the capacity verification method of the automobile tank truck.

What is the capacity of the tank truck?

Tank trucks are dangerous goods transportation vehicles. If the tank body material is too thin, the corrosion resistance and impact resistance will be weakened, posing safety hazards. Of course, the thickness of the tank body is not the better. Excessive thickness of the tank body material will increase the weight of the tank truck, increase fuel consumption, and reduce the net volume of the tank body. The price of the tank truck will increase. What is the thickness of the tank body? Is it appropriate?

The thickness of the small tank body of the tank body made of carbon steel and stainless acid-resistant steel should meet the following requirements:

The design volume of the tank is less than 11 cubic meters, the rated capacity is less than 9.6 cubic meters, and the thickness of the small tank is 4mm;

The design volume of the tank is 11-24 cubic meters, the rated capacity is 9.6-22 cubic meters, and the thickness of the small tank is 5mm;

The design volume of the tank is 24-30 cubic meters, the rated capacity is 22-28 cubic meters, and the thickness of the small tank is 6mm.

The anticorrosive body of the small white can made of aluminum and aluminum alloy, with a thickness of 5mm.

The calculated thickness of the tank is calculated according to the following formula:

tank truck

δ = Pc Di / (2 [σ]t φ)


δ — Calculated thickness of the tank, in millimeters (mm);

Pc—Calculated pressure, in megapascals (MPa);

Di — the diameter of the tank body, in millimeters (mm);
[σ]t—The allowable stress of tank material at design temperature, in megapascals (MPa);

φ — Welding joint coefficient.

Characteristics of Tank Truck

Patented tank: easy to use

When it comes to the transportation industry, safety is always a topic that cannot be avoided. Linyu’s “small white tank” adopts a streamlined design with an exclusive patent, which not only has a fuller and smoother appearance, but also has better compression resistance and a lower center of gravity, making it safer and more secure during driving.

As a special vehicle for transportation, customers value the practicality of the tanker more. The most troublesome thing in the transportation industry is the unclean unloading of tankers, which leads to “the journey is not worth it.” In order to solve this problem, the small white tank adopts a larger fluidization angle to ensure that the discharge is faster and the discharge residue is less, so that the customer can maximize the profit for each transportation.

Intelligent manufacturing: exquisite

The body of the small white can is beautiful in color and beautiful in appearance. They are a beautiful landscape when they start in batches; when driving on the highway, the small white tank is definitely the most beautiful boy among the tankers.

Moreover, the small white cans are not only good-looking, the whole vehicle parts adopt large-scale laser cutting machine, CNC plasma cutting, digital production line, internationally renowned CNC automatic welding, stable and reliable quality. Coupled with its short wheelbase and low center of gravity, it is designed according to the smallest loadometer and it is more flexible to drive.

Lightweight configuration: compliant

Affected by the country’s policy of overtaking control, the tanker industry increasingly favors “lightweight” products. The small white tank body is equipped with lightweight legs, aluminum alloy wheel covers, lightweight axles + aluminum rings, aluminum alloy upper platforms, selected high-quality high-strength steel plates and aluminum alloy plates, which are high in hardness and lighter than other materials. It can increase the service life of the tank body and reduce the weight of the tank body. The vehicle is not only compliant, but the transportation volume can also satisfy customers when the vehicle weighs only 5.6 tons.

Since the launch of Linyu small white cans, it has been widely recognized by the market for its fresh and beautiful appearance, lightweight design, wide range of transportation media and excellent product quality. It has quickly spread in the powder cans transportation market across the country and has gained Unanimous praise from our customers and friends.

What are the material advantages of Linyu cement bulk carrier?

With the increasingly strict regulations and policies of modern logistics transportation vehicles, such as over-regulation and regulation, “lightweight” technology has become a hot issue in the special-purpose vehicle industry at this stage. Especially since the implementation of the “Regulations on the Management of Over-limit Transport Vehicles on Highways”, various domestic markets have set off a climax of demand for lightweight cement bulk carriers. However, cement bulk carriers made of high-strength steel materials have become the bottleneck of lightweight technology. .

Linyu automobile deployed ahead of schedule. After careful selection by the R&D team, it chose lighter weight and stronger aluminum-magnesium alloy as the material to break the situation, and launched the aluminum alloy powder material transportation semi-trailer in 2018. After two years of continuous optimization and upgrading, dimensions, dead weight, structure, performance and other aspects have been comprehensively improved, becoming the representative of the market “safe and worry-free, fast running”.


Material advantages of cement bulk carrier

1. The density of aluminum alloy is only about 1/3 of that of steel. The application of aluminum alloy materials on the Cement Bulk Carrier can greatly reduce the quality of the cement bulk carrier.

2. The aluminum alloy tanker has high strength, good ductility and more than twice the wear resistance of ordinary steel plates. It is safer and more efficient in transportation. It is definitely the first choice for the transportation of powder materials.

3. The aluminum alloy tank body can conduct the static electricity generated during the loading, unloading and transportation of materials in time, reducing the probability of accidents.

4. Due to the high corrosion resistance of aluminum alloy, there is no major damage to the car body when the vehicle reaches the mandatory scrapping period, and the recovery value of the higher strength steel of aluminum alloy is high.

Linyu has always maintained its original intention, whether it is from material, safety, etc., continuous optimization to provide customers with higher efficiency and more considerate services.


Patented appearance, high transportation efficiency

The external shape of the patented tank is beautiful and atmospheric, the structure design is reasonable, the volume rate is 97%-98%, and the transportation efficiency is higher.

Reasonable configuration, low residual rate

The tank has a large diversion angle, no dead corners of accumulated materials, reasonable layout of the fluidized bed, and a residual rate of less than 0.3%, which is more efficient and more profitable.

Optimized design, flexible and convenient

In order to adapt to the usage scenarios, Linyu has made special optimizations based on the innovative design ideas of aluminum alloy cement bulk carrier. It adopts a short wheelbase design, which can easily load a 12-meter loadometer. The length of the vehicle is short and the vehicle is more flexible.


Human accessories, safe and secure

The aluminum alloy anti-skid walkway, aluminum alloy wheel cover, aluminum alloy ladder, etc. have been humanized upgrades, which are light in weight, more convenient and safe to use.

From non-standard to standard, from arbitrary development to standardization, is the common law of the development of all industries. Linyu has been actively exploring on the road of legal compliance and lightweight, using advanced manufacturing technology to ensure product process stability and reliable performance; with more high-quality products and more intimate services, it helps the powder material transportation industry to be scientific and efficient development of.

What are the common sense of using spray truck?

Spraying trucks play a very important role in our lives. It is very important for the cleanliness of our city. We have all known about its operation and use. For those who operate it, we must be clear about the role of spraying trucks. Use common sense to help operate the sprayer carefully and better.

1. Requirements for water sources: When the sprinkler uses river ditches and ponds as water sources, pay attention to all the ends of the suction pipes are submerged in the water. In order to avoid inhaling rocks or more mud, sand and floating debris, the end of the suction pipe is generally equipped with a filter device. It is strictly forbidden to remove the filter device when absorbing water. If the water source is shallow, you need to dig deeper at the suction point in advance to ensure that it does not contain debris and air. The water pumps of different spray 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 excessive sand in the water.

2. Tips for adding water to spray trucks: Before the centrifugal water pump sucks water, a certain amount of water needs to be added to the pump, and the water filling port needs to be closed after the addition. When the self-priming water pump starts to use, it needs to add water, and there is no need to add water in the future.

3. The water inlet pipe of the spray truck needs to be vacuumed: the water inlet pipe system needs to maintain a certain degree of vacuum when sucking water in order to suck water into the tank. The water inlet pipe system must be sealed and reliable, the hose must not be damaged, and the hard pipe must not have cracks, otherwise air leakage will occur and the water cannot be sucked.

4. Common sense of parking and gear shifting: Whether the sprinkler is before absorbing water or before sprinkling, the power take-off device needs to be shifted when parking.

5. Common sense of water release in winter: Before winter comes, the water in the pump and water pipe should be emptied to prevent freezing and cracking. In northern my country, there is generally no construction in severe winter, so after the completion of the construction, the water in the pump and the water pipe is immediately drained to prevent future troubles.

6. Precautions for spraying truck sprinkler: The front nozzle of the spray truck is lower, close to the ground, and the spray pressure is higher, which can be used to wash the road; the rear nozzle is higher (the rear nozzle of the sprinkler is generally installed on the left and right), and the spray surface is wide , It can be used for road construction sprinkler. When using the rear sprinkler, the front sprinkler should be closed; when using the adjustable sprinkler, the sprinkling width can be adjusted as needed. The wider the spraying vehicle, the less the amount of overlap in the middle, and the more uniform the spraying density.

7. Spraying truck lubrication and fastening skills: Lubricate the lubrication points of the transmission assembly regularly during use, and frequently tighten the connection points to ensure normal use.

8. Common sense of regular sewage discharge of spray truck: The water storage tank of spray truck is equipped with a sewage pipe, and the inlet of this pipe is the low point of the water tank. After a period of use, the drain pipe switch should be turned on regularly to remove the debris accumulated in the tank until the water becomes clear.

The above several introductions about the use of spray trucks are worth learning. The use of these skills can also make us more efficient in operation, and the equipment will not be damaged, and we should not Forgot to maintain our equipment properly.
