How to solve the noise of basement water pump?

Solutions to noise in basement pump house;

1. The wall around the pump house is insulated and sound-absorbed, with a thickness of 10cm, and consists of anechoic cavity, sound insulation board, porous sound-absorbing layer, fiber fabric layer and professional perforated plate. The roof sound absorption treatment consists of anechoic cavity, sound absorption plate, porous sound absorption layer, fiber fabric layer and special sound absorption ceiling plate with thickness of 80- 100cm; Through this measure, part of the low-frequency noise in the pump room is isolated and eliminated, and the noise reverberation in the pump room is eliminated.

2. Separate the domestic water pump and the fire water pump in the pump room with brick-concrete walls, and install sound-proof doors to carry out targeted noise reduction treatment to reduce investment.

3. Install an intake and exhaust muffler at the intake and exhaust of the inner pipe to reduce the direct diffusion of noise in the pump room, thus eliminating the impact of this reason on residents.

4. The rigid connection between the pipe wall and the wall is changed to flexible connection, which can achieve better shock absorption effect.

5. Replace the fire door of the pump room with a soundproof door, so as to eliminate the noise of the pump room from spreading outward through the underground garage and eliminate the impact of this noise on residents.

6. In addition to meeting the process requirements, the sound-absorbing board on the wall and ceiling of the pump room should be moisture-proof, high in strength, beautiful in appearance, long in service life and maintenance-free.
