Vacuum pump pressure affected by those factors _

vacuum pump is a kind of in confined Spaces, through various methods to improve and maintain a vacuum device. But if in the closed space with pressure relief, vacuum pump can appear the problem of insufficient pressure, affect the normal operation. To avoid this problem, today small make up to introduce the following content. In the several reasons of the lack of pump pressure and the corresponding solutions.

1, such as vacuum pump, no water filling or proper discharge, the solution is: check whether the pump casing and the inlet piping is full of liquid.

2, too slow. Solution: check the electric wiring is correct, the voltage is normal or turbine steam pressure is normal.

3, the system of high water head. Solution: check system head ( Especially the friction loss) 。

4, or inlet air leak, solution: check the inlet pipe are free to change and/or gas leakage.

5, intake stroke is too high. Solution: check the existing WangTou.

6, bottom valve, or submerged depth of the inlet pipe is not enough. Solution: consulting manufacturer to obtain the correct submerged depth or eliminate vortex with baffle.

7, pressure gauge position is not correct, solution: check whether the position is correct, check the outlet nozzle or pipe.

8, impeller diameter is too small. Solution: please consult manufacturer correct impeller diameter.

the problem of insufficient pressure vacuum pump may be due to one or more reasons. When the water pump appear this kind of failure in the operation process, should find out the reason seriously, take targeted measures to solve.
