The vacuum pump of the suction and suction truck driven by a certain original car is overloaded and even turned. Usually this phenomenon is called “stickingâ€. There are several reasons why the suction pump vacuum pump jam occurs: First, the spring is damaged, so that the vacuum pump rotary tablet is not uniform. Second, improper assembly, so that a local force is too large. Third, due to the air inlet filter lost or damaged, resulting in external dirt, metal, glass chips and other foreign objects fall into the vacuum pump chamber. 4. The gap between the rotor of the vacuum pump, the end surface of the rotary vane and the end cap is too small, friction and heat cause the rotary vane to stretch or overheat and the friction of the rotary vane is too high, resulting in deep scratches on the end surface, and finally the seizure occurs. . 5. When the long axis of the vacuum pump is tightly fitted with the shaft sleeve, the lubrication oil path is not smooth, and the vacuum pump may be stuck due to mutual adhesion. Six, suction truck vacuum pump for a long time, the pump cavity rust. 7. When the working environment of the internal vacuum pump is excessively humid, and the oil in the pump deteriorates or scales, the rotor is cracked at the moment of starting. All of the above conditions will cause the vacuum pump of suction pump and suction truck to get stuck. These conditions are very dangerous, because at the moment of jamming, due to overload or rotation of the rotor, it is easy to burn the motor or power take-off and damage the gearbox. Even if the motor or power take-off device is not burned out, if it is not stopped in time, it will damage the pump chamber, destroy the rotary vane, spoil the rotor, burn the end surface, etc., causing the vacuum pump to be severely damaged and unable to be repaired. In short, the suction pump vacuum pump, suction pump vacuum pump stuck always occurs in the rotor, between the rotor and the end face or intermediate partition; or between the rotor and the vacuum pump cavity. These parts are the key parts to determine the ultimate pressure of the vacuum pump. Therefore, if a stuck phenomenon occurs, it is necessary to stop the pump urgently, eliminate the malfunction, and repair it properly. Do not try again or even be reckless, otherwise it is very easy to cause the vacuum pump to be scrapped, unable to repair and other serious consequences.
