With the improvement of living standards, low-frequency noise sources have repeatedly appeared in residential buildings, especially the low-frequency noise generated during the operation of pump rooms in high-rise buildings, which has had a considerable impact on the lives and health of residents. The low-frequency noise of the booster pump has strong penetrating power into the building. If you are exposed to low-frequency noise for a long time, you may easily suffer from neurasthenia, insomnia, headache and other adverse symptoms. The following brings you a brief description of the booster pump noise control plan.<\/p>\n
1. Noise source analysis
\nThe working noise of the booster pump mainly includes: aerodynamic noise generated during the transportation of gas\/liquid, structural noise caused by vibration of the motor casing, noise generated by vibration of the machine base, and noise from the motor.<\/p>\n
2. Measures to control booster pump noise
\n1. It is relatively easy to deal with aerodynamic noise in terms of pump body noise control. Commonly used methods include adding sound insulation covers and using sound-absorbing materials.
\n2. For vibration isolation of the booster pump system, we generally use a vibration isolator. If the vibration of the pump body is strong, floating ground is preferred, because the floating ground has a better shock-absorbing effect and can play a vibration-absorbing frequency band. Wider, too.
\n3. Comprehensive damping and sound insulation wrapping is performed on the pump body pipeline. On the one hand, it can reduce the vibration of the pipeline, and on the other hand, it can also play the role of isolating air sound.<\/p>\n
3. Effect and user evaluation
\nAfter treatment, the noise value of the booster pump room dropped below 30dB(A), meeting national requirements.
\nResidents reported that the “buzzing” noise upstairs has been significantly reduced, and their families can rest normally. Other upstairs neighbors can basically no longer hear the noise of the booster pump.<\/p>\n
Booster pump noise control is a professional and systematic renovation project. Acoustic design and processing should be done jointly from the sound source, propagation and user receiving end, so as to minimize the impact of pump noise on residents and build a A peaceful space and a harmonious living environment require professional noise reduction technology analysis and production solutions.<\/p>\n","protected":false},"excerpt":{"rendered":"
