If there is noise in the vacuum pump, there may be an internal problem. Today, we talk about the noise sources and solutions of vacuum pump.
- Adopt a variety of cylinder block composite structure, of course, the number of cylinder blocks should be reasonable, and the layout should be comprehensively considered the actual application.
- It can also be equipped with mechanical vibration damping device. Of course, this device is mostly used in high-speed pumps and pumps with large pumping speed. The method of vibration damping is to install shockproof rubber on the pump base.
- Vibration caused by fluid action. For example, the working point of the pump deviates from the best efficiency point seriously: uneven liquid flow and unstable return flow are generated in the blade; local pressure reduction causes cavitation, etc.
- Adjust the pump structure, use the actual needs to design the set-up type, bedroom and other types of pumps, in actual use, because the horizontal structure has the characteristics of compact, low center of gravity, more conducive to the reduction of vibration and noise.
- Adopt dynamic balance mode. Usually, the inertia force of eccentric wheel and slide valve can be balanced and reduced by analysis and calculation, then adding balance wheel and adding balance weight or balance wheel on the belt pulley. The practice shows that it is an effective method of vibration reduction.
- Vibration caused by mechanical reasons: such as rotor component imbalance, pump, motor, coupling misalignment, shaft bending, gear tooth surface wear, sliding bearing oil film vibration, rolling bearing track, steel ball out of round or inside and outside, ring falling off, excessive pipeline resonance caused by unreasonable design or thermal expansion, foundation bolt loosening, etc.
