2 bv water ring vacuum pump pressure is insufficient reason and solution

in the working process of the 2 bv water ring vacuum pumps, gas is isothermal process, so the compression and extraction of flammable and explosive gas, the explosion not easily, so get the more extensive application.

so, in use process, water ring vacuum pump pressure is not enough, what should I do?

1, 2 BV water ring vacuum pump is not filled with water or exhaust incorrect:

solution: check whether all in the vacuum pump shell and the inlet pipe full of liquid.

2, low speed:

solution: check whether the motor wiring is correct, the voltage is normal or turbine pressure is normal.

3, the system head too high:

solution: check the system of the head ( Especially the friction loss) 。

4, 2 BV water ring vacuum pump high electron:

solution: check the existing WangTou ( Inlet pipe is too small or too long can lead to the larger friction loss) 。

5, the impeller or pipe is blocked:

solution: check the obstacles.

6, the direction of rotation error:

solution: check the direction of rotation.

7, air or leaks in the suction line:

solution: check the air in the intake pipe road hole and/or gas leakage.

8, 2 BV or water ring vacuum pump of the stuffing box packing seal wear and air leakage into vacuum pump shell:

solution: check the packing or seal, and according to the need to change to check whether the lubrication is normal.

9, heat pump or volatile liquid suction head:

solution: please consult the manufacturer in order to increase suction.

10, 2 BV water ring vacuum pump bottom valve is too small:

solution: install the correct size of the bottom valve.

11, or at the bottom of the valve inlet tube not deep immersion:

solution: consult manufacturer right immersion depth, and damper is used to eliminate the eddy current.

12, 2 BV water ring vacuum pump impeller clearance is too large:

solution: check the clearance is correct.

13, damage of impeller:

solution: check the impeller and according to the need to change.

14, impeller diameter is too small:

solution: consult manufacturer correct impeller diameter.

15, 2 BV water ring vacuum water pump pressure gauge position is not correct:

the solution: check whether the position is correct, check the outlet nozzle or pipe.
