Tank semi trailer is a kind of vehicle specially used for the transportation of liquid cargo, mainly used for the transportation of various oil products, such as gasoline, diesel, kerosene, etc. It is usually composed of two parts: tractor and semi trailer.
- First, structural characteristics
- Tank body
- Material: Generally made of high quality steel, with good strength and corrosion resistance. Common tank materials are carbon steel, stainless steel and so on.
- Shape: Usually cylindrical, this shape can maximize the use of space and improve the loading capacity. The two ends of the tank are generally oval heads to enhance the strength and tightness of the tank.
- Volume: The volume size of the tank semi trailer varies according to the model and use, generally ranging from dozens of cubic meters to hundreds of cubic meters.
- frame
- It consists of longitudinal beams, beams and support beams with sufficient strength and stiffness to withstand the weight of the tank and cargo.
- The frame is usually also installed with a variety of ancillary equipment, such as guard rails, spare tire frames, tool boxes, etc.
- Suspension system
- Multi-axle air suspension or leaf spring suspension is used to improve the driving stability and comfort of the vehicle.
- The suspension system can also automatically adjust the height according to the road conditions to ensure the safety of the vehicle in different road conditions.
- Brake system
- Equipped with advanced braking system, including air braking and hydraulic braking two ways. The air brake system has the advantages of fast braking response and large braking force, which is suitable for heavy duty transportation. The hydraulic braking system has the characteristics of stable braking and high reliability, which is suitable for high-speed driving.
Material and process
The tank body is usually made of high-strength high-quality steel plate, which is treated by a fine welding process to ensure that the weld is strong and no leakage.
In order to enhance corrosion resistance, the surface of the tank may be treated with special anti-corrosion coatings, such as spray, galvanized, etc.
Head design
The heads at both ends of the tank are generally oval, which is better able to withstand the pressure of the internal liquid and is also easy to manufacture and install.
The connection between the head and the tank body adopts a fully welded structure to ensure the tightness and strength.
The wave board is set
The tank is usually equipped with a multi-channel wave shield to reduce the fluctuation and impact of the liquid during transportation.
The shape and position of the wave plate are carefully designed to effectively prevent liquid sloshing without affecting the efficiency of loading and unloading the cargo.
