Vacuum suction pump vacuum pump stuck causes

Due to some reasons, the vacuum pump of the vacuum suction truck is overloaded to operate, and there is a situation where it cannot turn up. We call this type of condition a stuck condition, which can cause the vacuum pump stuck in the suction pump to be the main cause of jamming. Based on experience Summarized for several situations:

1. When the shaft of the vehicle vacuum pump and the long shaft match too tightly, there is a problem that the lubrication road is not smooth, and the vacuum suction truck is also caused because of the stickiness between the two. The vacuum pump stuck.

2. Due to improper assembly, a certain part of the vehicle has experienced excessive stress.
3. The filter of the air inlet has been damaged and lost, causing foreign matter such as metal and foreign objects to enter into the cavity of the vacuum pump of the vehicle.

4. The pumping environment of the vacuum pumping vehicle is too humid, causing the oil in the pump to deteriorate or fouling, and the rotor will be cracked at the moment it starts.

5. Because the gap between the end face of the rotary vane of the vacuum pump and the end cap of the rotor is too small, in the course of friction and heat, the rotary vane stretches or is too tight and hot friction will cause the hardness of the rotary vane to be too large. Causes the end face to produce deeper scratches, and eventually the stuck-sintered case occurs.

6. The spring is damaged, which causes the uneven force of the rotary vane of the suction pump vacuum pump.

7. The idle time of the vehicle makes the vacuum pump not practical, and the rust will appear in the pump chamber.

If the vacuum pump is stuck, it is dangerous because the vacuum pump of the suction truck is in the moment of jamming. It is easier because the overload of the rotor or the rotor cannot be switched. There was a situation where the power take-off and the motor were burnt, and the gearbox was damaged. If this is not the time to stop, then it will reduce the pump cavity grind, burn out the cross section, wrecking the rotor, etc., the most serious is that it will lead to the vacuum pump oil can not be repaired, and can only be replaced.
