Question 1: Why is the suction power of the sewage suction truck low?

Answer: The rear cover of the sewage suction truck is not closed tightly; the sewage ball valve of the sewage suction truck is not closed tightly; the sewage suction tank and the sewage suction pipe are damaged; the visual window is leaking.


Question 2: What is the application of the sewage suction truck?

Answer: The sewage suction truck is a new type of sanitation vehicle that collects, transfers, cleans, and transports sludge, sewage, and avoids secondary pollution. The sewage suction truck can self-absorb and discharge. It has fast working speed, large capacity and convenient transportation. It is suitable for collecting and transporting feces, mud, Liquid substances such as crude oil.


Question 3: What should I do if the front wheel of the sewage suction truck is abnormally hot?

Answer: The hub is in the innermost part of the brake drum, which is the axle head where the bearing is installed after disassembly. Its high temperature is generally caused by the bearing assembly being too tight or poor lubrication. Too high temperature will cause the grease inside to melt and flow out and affect the braking effect. In severe cases, it will burn the bearing. Generally speaking, its temperature is relatively normal within 50 degrees above the ambient temperature. If the axle of your dirt suction truck is hot, be careful, because the bearings inside may be too tight or abnormally worn.

The brake drum is commonly known as the "pot". As long as you step on the brake, it will heat up. It is the place where the heat is the largest in the entire front wheel. The temperature of the brake drum is related to the ambient temperature, driving speed, number of brakes, weight of the car, and road conditions. If you step on a few brakes, the temperature of 100-200 degrees can be reached, and even heavy trucks can reach it when downhill. Above 300 degrees, there is no clear data regulation in the current national regulations and standards.

If the brakes do not return or wipe the drum a little, it is not only difficult to test it on gentle slopes, but in high temperature weather, the temperature of the brake drum will rise rapidly. If the high temperature is transmitted to the rims and tires, it is indeed very dangerous in the hot summer.

Sewage suction truck manufacturers need to remind everyone that as long as the brakes are stepped on, the brake drums of all vehicles will get hot. The faster the speed and the heavier the car, the higher the degree of heat generated by the brakes. This is the principle of energy exchange.
