Many users report that their own water ring vacuum pump often produces noise in the process of use, and the higher the pumping rate and vacuum degree of the pump, the greater the noise. The following content for you to introduce the cause of the water ring pump noise and specific solutions, you can refer to!

1. Large noise of the motor: if the noise of the water ring vacuum pump is caused by the large noise of the motor, the motor with low noise can be selected or the motor acoustic cover can be added.

2. Loud noise caused by installation: check whether the equipment foundation is installed firmly to avoid vibration; the motor shall be aligned with the pump coupling to avoid noise and vibration caused by insufficient connection accuracy.

3. Noise caused by vent of exhaust port: if noise is caused by this problem, muffler can be installed at the outlet.

4. The vacuum pump works under the limit vacuum: the limit vacuum of the water ring pump disc distribution board structure vacuum pump is 33hpa (absolute pressure), which will vibrate and increase the noise when it works at 50hpa generally. The limit vacuum of the water ring pump of the vertebral body distributor structure is 100hPa (absolute pressure), which will vibrate and increase the noise when it works at 110hpa generally. Therefore, we should correctly select the vacuum pump and avoid working at the extreme Vacuum limit.

5. Mechanical friction: we should often remove scale to avoid excessive noise caused by mechanical friction.

When the noise of the water ring vacuum pump is too loud in use, we should find out the cause of the noise in time, so that we can take targeted measures to solve the problem.
