How To Carry Out Vacuum Pump Noise Control?
Jul 02, 2019| What should I do if there is noise in the vacuum pump? Vacuum pumps generally generate noise due to operational problems during use. Long-term noise will affect people's physical and mental health, and will also disturb the lives of surrounding residents. Therefore, noise management of vacuum pumps is required. How to carry out vacuum pump noise control?
I. Analysis of noise source of vacuum pump
The vacuum pump noise includes mechanical noise during operation, air noise of vacuum pump exhaust, vibration noise of vacuum pump piping, etc. The main type of noise is medium and low frequency noise, which should be treated from the aspects of sound absorption and sound insulation.
Second, vacuum pump noise control measures
1. If there is a machine room in the vacuum pump unit, the machine room shall be soundproofed and decorated. The sound insulation materials and vibration damping materials shall be used on the indoor walls and floors, the soundproof doors and windows shall be used, and the muffler shall be used for the ventilation openings of the machine room to greatly reduce the noise of the vacuum pump.
2. For the vibration noise of the vacuum pump itself is a big problem, you can use the vibration damping pad on the ground of the machine room, or use the vibration damping device under the pump body, use the elastic support frame for the pump body connecting pipe, and use the damping damping material for dressing. Reduce the vibration and noise of the entire device.
3. The exhaust noise of the vacuum pump is mainly processed by the muffler. According to the noise frequency determined on site, the appropriate noise is designed and manufactured. The vacuum pump muffler is generally a composite muffler, which has the advantage of wide noise reduction frequency, the outer steel plate of the muffler is made, and the internal structure is many. Made of stainless steel
4. For the pipeline outside the vacuum pump room, use damping material to wrap, such as glass wool and glass cloth to further reduce the vibration and noise of the pipeline.
Vacuum pump noise control comprehensive noise reduction through suction and noise reduction and other measures to reduce the impact of vacuum pump noise on the periphery.
