NYP high viscosity insulation pump noise control technology and sound insulation noise reduction scheme
NYP high viscosity insulation pump / pump room noise is mainly two kinds of noise sources: 1, the noise generated by motor operation and the aerodynamic noise generated by the gas / liquid during transportation, called airborne noise. In the low octave band, it is in the range of about 100-450 Hz. The sound source belongs to the steady-state noise NYP high-viscosity heat preservation pump noise control technology and sound insulation noise reduction scheme when the pump room is in normal operation.

NYP high viscosity insulation pump / pump room noise is mainly two sources of noise:
1. The noise generated by motor operation and the aerodynamic noise generated by the gas/liquid during transportation are called airborne noise. The peak of such noise level is mainly concentrated in the low octave band, which is in the range of 100-450 Hz. The sound source is a steady-state noise when the pump room is operating normally. Pipeline noise is the noise generated when an oil stream flows through a pipe. In addition, the cavitation phenomenon of the NYP high-viscosity heat preservation pump and the phenomenon of stopping the pump oil hammer can also generate instantaneous noise. The noise generated by the oil pipeline is affected by the flow rate and pressure. Causes noise pollution to the surrounding environment.
2, is the solid structure noise excited by the vibration generated by the motor running along the structure. The low-frequency vibration generated by the rotation of the motor when the NYP high-viscosity heat preservation pump is running propagates along the structure, which has a great influence on the upper/lower room. The noise is sometimes as high as 55dB or more, and the low frequency noise of the cockroaches makes people feel uncomfortable. Vibration transmission can be up to 30 layers. Such noise level peaks are mainly concentrated in the low octave band, which is in the range of approximately 100-450 Hz. Therefore, it is necessary to design a shock absorption and sound insulation technology for the NYP high-viscosity heat preservation pump and pipeline for low-frequency vibration, and adopt shock absorption and sound insulation treatment. From our practice, it is necessary to use multi-stage vibration isolation technology to isolate the vibration transmission of different frequencies for such low-frequency vibration. Thereby achieving the goal of shock absorption and noise reduction.
The noise generated by the whole set of pumping facilities is mainly mechanical noise. At present, the method of controlling noise in acoustic principle is more commonly used to control the propagation of noise. Botaibang mainly has sound insulation, sound absorption and noise reduction. Sound insulation is the use of sound insulation structure to separate the sound source from the sound point; sound absorption is to use noise absorption structure or sound absorption material to reduce noise; noise reduction is the use of impedance, resistance, porous diffusion and other principles to reduce the noise value.
Noise control measures should make full use of the site environment and conditions based on acoustic principles. Such as:
1. According to the pump room environment, the pump room with the sound source is not tightly sealed shall be soundproofed, and the room where the pump room generates noise shall be treated with sound absorption/sound insulation, and the doors and windows shall be soundproofed.
2. Control the noise generated by machine equipment and equipment parts. The new pumping station NYP high-viscosity thermal insulation pump should be based on heavy weight to prevent vibration from generating noise. Moreover, a rubber vibration isolating pad should be provided for vibration isolation to reduce vibration noise; each NYP high-viscosity heat preservation pump unit is separately provided with a foundation to prevent resonance. Use “soft†coupling on the NYP high-viscosity heat-insulating pump suction and pressure pipe as much as possible. Regular maintenance, problems such as oil leakage, loose parts, equipment parts, mechanical vibration, etc. should be repaired in time to reduce noise.
Because different manufacturers and types of NYP high viscosity insulation pumps, the working principle and structure will be different, so the site survey and analysis of the noise source is very important for the pump room noise reduction scheme design and material selection.
