As is known to all, the screw vacuum pump is a pair of screw, in the pump shell for synchronous high-speed reverse rotation and the air suction and exhaust effect of odor equipment, is also the replacement of oil-sealed vacuum pump.
In the long run, the screw vacuum pump may have some problems. Today, hangzhou xin 'an river industrial pump and you to discuss what causes the screw vacuum pump pumping is not complete:
1. The screw vacuum pump was not filled with enough water before starting. Although the water seemed to overflow from the air outlet, the gas was not completely discharged due to the absence of rotating pump shaft
2, human error caused the screw vacuum pump suction pump is not complete, some because of the damage of the main motor, just add another motor to push, the result of the screw vacuum pump total flow is small, the pump head is low and even do not enter the water
Therefore, the use of screw vacuum pump to standard use, will not lead to the life of screw vacuum pump shortened
Dry screw vacuum pumps are used in the battery industry
