Most of the water pump room is really the basement of the building, if the water pump does not have good noise reduction measures, it will bring serious noise hazards to the surrounding. The low-frequency noise of the water pump has a very big impact on the occupants. Noise reduction of water pumps has always been a great concern to residents.
First, the pump noise source analysis
1. The vibration generated by the pump in operation caused by the noise of the whole device.
2. The noise generated by the vibration of the seat is mostly low-frequency noise, the peak value of which can reach up to 450 Hz. This sound source is a stable source.
3. Pipeline noise water flow in the pipeline according to the size of the water flow, speed and pressure of the noise.
Noise reduction measures
Noise management should be based on the environment to choose the appropriate noise reduction measures, to give full play to the environment to bring favorable factors.
1, pipe vibration treatment
First of all, the noise generated by the water in high-speed movement, the installation of impedance shock absorbers. Secondly, the pipeline is given a sound-absorbing bandage, and then paved outside the pipeline to reduce the low and mid-frequency sound-absorbing body.
2、Base vibration isolation table
Pump operation because the unit vibration caused by low-frequency noise, need to be installed at the base of the vibration isolation table. The pump special low-frequency vibration isolation platform with stable performance can effectively reduce the noise impact of vibration.
3、Machine room noise
Various types of noise generated in the engine room, resulting in a higher sound pressure level in the engine room. Selection of suitable and efficient sound-absorbing equipment. Laying in the machine room walls and the top surface, the noise in the machine room is significantly reduced.
Pump noise management is the first vibration damping, followed by sound insulation for pump room noise reduction can play a good sound insulation and noise reduction effect. Hangzhou Hanks has many years of experience in water pump noise reduction, can provide a comprehensive water pump room noise reduction measures.
