Suction trucks are filled with excrement. If an explosion is encountered, the excrement on it will leak to the surroundings. People, the ground, and various materials will be contaminated with feces. This is a terrible thing. Must be able to effectively curb. At present, there has been an accident of “suction truck explosion†in Guangxi, which has caused many people to worry about the explosion of the suction truck and fear that they have encountered an explosion of the suction truck. What is the reason for the explosion of the suction truck ?
Suction truck explosion causes:
1. There is too much biogas in the body of the suction truck, and it is fermented and explode when it encounters the chemical action of the biogas. The probability of this kind of situation is relatively small, because the body of the suction truck is mostly made of steel. It is not so easy that it will explode. However, it is not absent because the power of biogas fermentation is great.
2. The suction truck was not operated in accordance with the standard procedure during the suction operation. The illegal operation caused the suction truck to explode. This is the main reason for the suction truck to explode. We all know that the suction truck is a vacuum type. It uses the vacuum pump to remove the atmosphere from the tank, and then uses the atmospheric pressure to suck the fecal matter through the suction pipe. The diameter of the suction pipe is about 50cm, which is the size of the normal pipe. If there is a blockage of solids such as stones, the operator does not find it, and the blind pressure increases the suction of the manure and the pressure in the tank reaches a certain level. At the time of the explosion, the tank may suck flat and explode.
3. The materials used for the suction trucks are not qualified, and there is a case of cutting corners and materials. The unqualified welds and the thin body of the tank are more common. As a result, the suction truck cannot withstand tremendous pressure and suction in the work process. The explosion may occur. Such explosion accidents can be avoided completely by looking for a qualified manufacturer to purchase a qualified suction truck product.
What is the cause of the suction truck explosion ? Generally, as long as the above three reasons are avoided, it is possible to effectively avoid the occurrence of explosion accidents on the suction truck. Therefore, when purchasing the suction truck, it is necessary to select the products produced by the regular manufacturers. Check the suction truck to ensure that it is normal in all aspects and it is not easy to use the explosion in the process and affect oneself to influence others.
Thrust Ball Bearings are manufactured as single direction or double direction thrust ball bearings. They are designed to accommodate axial loads only and must not be subjected to any radial load.
Bearing features
Separable and interchangeable
The separable components of thrust ball bearings are interchangeable . This facilitates mounting and dismounting, as well as maintenance inspections.
Initial misalignment
Bearings with sphered housing washer(s) can accommodate initial misalignment.
Interference fit
Shaft washers have a ground bore to enable an interference fit. The bore of the housing washer is turned and always larger than the shaft washer bore.
