How to reduce the noise - water ring vacuum pump

during the use of water ring vacuum pump, will continue to produce a lot of noise, this will delay the normal work, many people will stop processing, but before to solve noise, we have to understand why this happens. Please brief us on the noise of the products.

1, water ring vacuum pump noise reasons, water ring vacuum pump body

1) vent exhaust noise can be created. We installed at the exit silencer.

(2) in the event of mechanical friction, can often clean up the balance, so as to avoid mechanical friction caused by too much noise.

(3) water ring vacuum pump in the vacuum limits will produce cavitation. By cavitation protection can reduce the shrill noise.

(4) noise caused by the installation of

check the coupling between the motor and pump. Avoid caused by a lack of connection precision caused by noise and vibration. Check whether the equipment base is firmly and avoid vibration.

5 vacuum pump work under limit vacuum:

1) Water ring pump plate distribution board structure limiting vacuum of vacuum pump for 33 hpa. Usually, when working under 50 hpa, it will increase the vibration and noise. Limiting vacuum of conical distributor structure of water ring pump for 100 hpa.

2) Usually, when work to 110 hpa, vibration and noise will increase. Please correct selection of vacuum water pump, and to avoid work under high vacuum.

2, pump body is noisy or motor noise? If the motor is making noise, the can choose low noise motor or motor noise cover installation.

1, reduce the working liquid flow rate.

concentricity between 2, vacuum pump and motor.

3, check the tightness of fasteners.

4, impeller and the pump shaft is loose, the vacuum pump and motor bearing is damaged.

5, whether there is foreign body in the pump cavity? If foreign body tell it rotating impeller, it will with the impact and noise.

cause water ring vacuum pump there are many factors that can produce noise, there are a lot of solutions, so everyone must find the problem before to solve the problem, so as to suit the remedy to the case. In addition, daily maintenance and maintenance is to prevent the equipment noise is an important task.
