the old pump noise is what reason? How to solve the problem of the noise from the pump

a, water pump noise is what reason is as follows:

pumps have noise treatment, also known as the pump noise, water pump, water pump vibration noise, belongs to the noise on the physical properties. In my basement of corporate governance of the riverside garden centrifugal pump noise control examples: 1. The pump itself running noise; 2. Because the operation of the pump, the cause of pipeline resonance; 3. The operation of the electric transformer noise; 4. Water pump operation cause the movement of water flow, the flow of the impact of noise, in general are produced by the pump running irregular, intermittent or random vibration, the pump noise control. noise analysis water pump room noise is caused by water pump working noise and motor noise such as comprehensive noise source. As the motor noise, mainly include: air dynamic noise and mechanical noise and electromagnetic noise, when the motor work, cooling air flow noise and high speed rotary blade fan noise of air dynamic noise. Mechanical noise including bearing noise and motor rotor unbalance rotor & other; Groove harmonic force & throughout; Effect of vibration and noise caused by structure. Electromagnetic noise is composed of alternating electromagnetic force between the stator and rotor, sewage treatment hysteresis expansion caused by pump room away from the noise transmission is the main way of air and solid sound transmission. Will greatly reduce the noise in the pump room, this is a misunderstanding. Attendant need time is becoming more and more short stays in the pump room, daily patrol or maintenance for a short period of time, have no influence to the health of the staff on duty, and a qualified water pump its noise level is generally about 85 db or so ( In accordance with GB/TQ38l l984) And manual workers hearing protection in China wastewater recycling allow fan noise is 70 & ndash; Vibration through the foundation walls and pipeline, it spread to the surface of the larger, such as diaphragm wall or the upper ceiling, wall and floor of the room, is due to the radiation condition improved, noise is obviously enhanced. The resilient pad to wall pipe installation. Although the measures to reduce the pump air noise inside the room didn't have much significance, but for reduce the noise effect is very obvious in this room, and the engineering cost can be controlled in ten thousand yuan of less than, engineering cost performance is very high.

relative to ordinary centrifugal pump with low noise pump products can choose shielding pumps, can also be driven by gas source of pneumatic diaphragm water pump
