1 The necessity of using aluminum for water tank
The self-weight of the chassis is a fixed value under the customer-defined conditions, and the quality of the tank body becomes a determinant factor that affects the quality of the oil truck product. If you want to effectively reduce the quality of the ground, you must first reduce the quality of the tank: while reducing the quality of the tank for the purpose of improving the load quality, you can only change the material of the tank and replace the carbon steel with other lighter materials, such as aluminum alloy. , Non-metals, etc. Based on the design technology and process experience of mature products such as aluminum alloy aircraft fuel trucks, it is inevitable to change the tank bodies and accessories of conventional fuel trucks to aluminum alloy materials. In addition, from the perspective of ensuring oil quality, the use of aluminum alloy materials is an ideal way.
2 Head and wave breaker
According to the international regulations of GB18564, the welding between the head and the simplified version must be butt welding, so the head type must be flanged. In order to improve its rigidity, a convex head is used, and its processing equipment is very mature. Only need to add drum press equipment, such as hydraulic press, etc. on the basis of ordinary flat head processing. The existing heads of aircraft refueling vehicles are cylindrical, which is difficult to process. Not only is it difficult to ensure the accuracy of the parts themselves, but the consistency of the parts in the same batch is also poor, and the processing requirements for simplified end faces are high. This form of heads is even more demanding. Suitable for plug-in welding.
The wave plate adopts the same type as the head, which helps to strengthen the rigidity of the simplified section. In order to improve its impact resistance and improve the force of the weld bead, the wave plate is welded with full welding. In addition, in order to reduce the impact of the liquid medium (oil) on the head, all or part of the manholes on the wave plate that is tightly necked with the head are added to improve the assembly and welding process of the wave plate and the simplified version. A layer of reinforced board is added between the anti-wave board and the simplified Chinese.
The material of the head of the wave breaker is the same as that of the simplified version, which is LF4. The wall thickness of the head is equal to or greater than that of the simplified version. The wall thickness of the wave breaker and the reinforcing plate is reduced by 1mm on the basis of the simplified version.
3 Left and right supports at the bottom of the aluminum for water tank
The left and right supports (ie auxiliary beams) still use the U-shaped form of the auxiliary beam structure of ordinary oil trucks. In order to improve the rigidity of the simplified section after load, all the saddle bolt holes and ribs measured on the outside of the support are stretched upward to form a saddle. The shape is beneficial to increase the length of the load-bearing weld and improve the stress condition. In order to increase the stability of the left and right supports, the ribs of the saddle bolt orifice plate measured on the supports can be connected in whole or in part to the left and right, so that the two supports become Overall, the thickness of the support plate is 6~8mm, and the material is LF6.

At present, the welding and appearance quality of the aluminum for water tank top coaming of oil trucks has always been a difficult point, especially the leaking pipe at the front end of the coaming, which is not only poor in installation and welding technology, but also can not perform the expected effect in actual use, so it is cancelled. In the outer measurement of the enclosure, a tank top walking platform and guardrail (movable barrier) are added. The walking platform adopts checkered plates or plate nets, and the plate fence is processed from aluminum pipes, and the height is not less than the maximum height of the tank top function device. In order to reduce the accessories on the outside of the tank and improve the integrity of the appearance, the oil and gas collection pipes, control air pipes, wires and leakage pipes on the top of the tank are all passed through the pipes that penetrate the upper and lower walls.

The lower part of the aluminum for water tank body on both sides of the aluminum for water tank body is replaced by the original carbon steel body with the same diameter aluminum for water tank.
