Reduce the pump noise analysis method and its technological research

Water pump noise is the main gas/liquid in the process of conveying the aerodynamic noise, the structure of the vibration excitation motor noise, stand for vibration noise, and the noise of the motor. Mainly concentrated in the low frequency band, such noise level peak at about 100-450 hz range. The sound source belongs to static noise in the normal operation of pump. Noise refers to water flow in the pipe produced by the noise. In addition, the pump cavitation phenomenon and stop pump water hammer transient noise also can produce. Feed water pipe noise, affected by the velocity and pressure.

The noise of the pump house of a complete set of facilities to produce mainly for the mechanical noise, at present the management method of noise on acoustic principle is commonly used is to control noise transmission way, sound insulation, sound absorption, noise elimination, etc. Sound insulation is the use of sound insulation structure will be sound source and the sound of separated points; Absorption is the use of sound absorption structures or reduce noise sound-absorbing material; Noise elimination is using the impedance and resistance, porous diffusion principle, reduce noise.

As far as possible should be according to the principle of acoustic noise control measures, make full use of the environment and site condition. Such as:

1, according to the pump room environment, the sound source closed imprecise insulation treatment was accomplished, the pump noise room take sound absorption/sound insulation, Windows and doors also should make insulation treatment, etc.

2, the noise control equipment and equipment parts. Based weight appropriate USES new pump house water pump, to prevent the vibration noise. And should use rubber vibration isolation cushion for vibration isolation, reducing the vibration noise; Each pump set the base alone, prevent to produce resonance. On the pump suction, pressure pipe connected by "soft" as possible. Preventive maintenance, problems such as loose packing leakage, equipment parts, equipment worn parts, mechanical vibration should be timely maintenance, such as reducing the noise.

Due to different manufacturers and types of water pump, the working principle and structure will have difference, so, conduct site survey and analysis of noise of pump room sound insulation noise reduction scheme design and material selection is very important.
