As a person who specializes in suction trucks, I must advise the owners of those who have modified and assembled the suction trucks to be cheap, but for the safety of themselves and others, please go to the formal channels to purchase cars. There are cumbersome testing procedures and modification procedures when the suction truck is assembled. It requires professional technicians and professional equipment to test the vehicle. Because the suction truck draws and inhales the air in the tank by a vacuum pump, a vacuum is formed inside the tank, thereby forming a differential pressure with the atmosphere outside the tank, and the suction and excrement operations are performed. When the suction truck is operated, The pressure on the tank body is huge. If the tank body of the suction truck is not firmly welded or the shape of the tank body cannot force the tank body as a whole, it can easily cause the tank body of the suction truck to swell or sag. The more serious consequences are. It is possible to cause a popping tank body burst like the above.

There is a strict production process for the production of suction trucks. Attention must be paid to various details such as piping design, valve assembly, and the size of the vacuum pump. In particular, the shape of the tank must be strictly symmetrical so that the average force of the tank can be achieved. Moreover, the thickness of the steel of the can body is also scientifically regulated. Being too thick makes it easier to increase the weight of the vehicle and the burden on the vehicle. Moreover, the vehicle is more fuel-consuming. When the thickness is too thin, the can body may easily deform due to the inability to withstand the pressure. After the suction truck has been successfully assembled, it must also perform strict tank pressure tests. One is to check the tightness of the tank; the other is to test the pressure on the tank. These are all important points in the production of suction trucks.
Today I saw a piece of news about a car owner buying materials and accessories needed to assemble a suction truck. Then he drove the car to a car repair shop and let the master of the repair shop make the modifications himself according to the samples purchased by friends, and then Without any detection, blind use, and eventually led to the tank body due to unbearable pressure during the pumping operation, the sudden expansion and burst, fortunately the owner was only slightly injured. Seeing this is not only a concern for those owners who have modified the suction truck.
Those small repair shops or small workshops do not have professional suction truck production technology, and there is no experience in the conversion of suction trucks and professional testing equipment. The suction trucks assembled in those places have many hidden safety hazards and are prone to problems. Therefore, I hope that all owners will not take risks because of wanting to be cheap or save money.
Do not pursue low prices and privately modify the suction truck
