A tanker truck is a special vehicle that is mainly used to transport petroleum-derived products such as kerosene, gasoline, diesel, and lubricants. According to the function, there are two types of tankers, the oil tanker and the refuelling tanker, which are used to carry the liquid oil. It is mainly composed of oil tanks, filling ports, drain valves, manhole covers, oil hoses, grounding chains, etc.; while the refueling car not only has the function of the oil tanker, but also can be used as a mobile pump station. It has added functions such as pump oil, metering, and control devices. The tanker we see at the gas station is a refuelling vehicle.
The most important thing for a tanker is its tank body. Most of the material is welded with a low-carbon steel plate. The two ends of the tank body are sealed with a head and the center is an oval interface tank. There are longitudinal and transverse wave barriers around. The interior is equipped with a partition. When the capacity is not large, the interior is a single room; if there is a large amount of oil to be installed, the entire tank body needs to be partitioned into several independent single rooms. Because when the vehicle is running, there is a certain gap in the liquid tank or it is not full, the liquid fluctuates in the container before and after, left and right, if the capacity of the container is large, the kinetic energy of the fluctuation is great, and the change of the mass center is also great. It will cause drastic changes in the axle load of the vehicle, which will seriously affect the stability of the car. Especially when the tank semi-trailer train runs uphill, if the container is large without partitions, the liquid flows to the rear of the container, resulting in a significant reduction of the axle load of the traction automobile drive shaft, which reduces the passability of the car train and makes The traction of the traction car is not fully utilized, and when the vehicle runs downhill, the liquid flows to the front of the container, which also causes the axle load of the traction car to change. Dividing a large-capacity liquid tank into several single chambers can improve the above situation. It is also possible to ship several different liquid cargos simultaneously on the same tank truck.
