Screw vacuum pump is a new generation of oil-sealed vacuum pump, which is widely used in domestic pharmaceutical, chemical, semiconductor and other enterprises that have high requirements for clean vacuum. The screw vacuum pump utilizes a pair of screws to perform an inspiratory and exhausting odor device generated by synchronous high-speed reverse rotation in the pump casing.

If the screw vacuum pump is not operated properly, it will cause the imported vacuum pump to not water. What are the reasons why the screw vacuum pump will not be watered?

1. The screw vacuum pump cools the circulating water too much, and the cooling circulating water flows back.

2, the imported vacuum pump speed is insufficient or flipped to cause the motor to burn

3, improve the screw vacuum pump seal box (alias packing), the upper pipe T2 copper rod wire drawing strand flange and other leaks

4, cooling circulating water?] There is an entry or water pipe blockage, the gate valve is not open

5, the screw vacuum pump disk leaks steam, the pump damage is serious or destroyed

6, improve the entrance and exit gate valve is not closed
