Air compressor noise reduction technology, air compressor noise control scheme, reduce air compressor noise

Air Compressor noise control technology and air compressor noise reduction scheme, Shenzhen Quelte Sound and Noise Reduction Engineering Technology Co., Ltd. specializes in noise control of mechanical equipment and noise reduction.

Air compressor is a power equipment widely used in industrial production , but the air compressor is very noisy when operating , usually in the range of 90~110Db(A), and it has low frequency characteristics, which seriously affects the surrounding environment, especially at night. It reaches hundreds of meters . Therefore, air compressor noise is a problem of industrial noise control are often encountered. Air compressors can be divided into two types, volumetric and vane, according to their working principle. Air compressors are a comprehensive source of noise. The noise of the air compressor is mainly composed of aerodynamic noise radiated from the inlet and outlet ports, mechanical noise generated by mechanical moving parts, and vibration of the driving motor .

Air compressor noise control method

First, the air inlet is installed with a muffler

Generally, the nearest port can be led to the outside, and then a muffler can be added. Since the intake noise has a low frequency characteristic, an impedance composite muffler, a micro-perforated composite muffler, a venturi muffler, and the like are generally installed.

Second , air compressor shock absorption

The air compressor has a large vibration, and it is usually necessary to perform shock absorption treatment on the base. The shock absorption design and shock absorption product selection are performed according to the weight and vibration frequency of the air compressor. The exhaust of the air compressor to the pipeline of the gas storage tank generates vibration and radiates noise due to the pressure pulse of the exhaust gas. It not only causes fatigue damage to pipes and supports, but also affects the surrounding environment. To this end, the pipeline needs to be protected against vibration and noise. Commonly used exhaust pipe is equipped with a cut-off orifice plate and avoiding the length of the resonance pipe.

Third , the air compressor installed sound insulation cover

In the case of high environmental noise requirements, for the noise of the air compressor, only installing the muffler at the air inlet often fails to meet the noise reduction requirements, and must also deal with the noise radiated by the casing and mechanical components, and install the whole unit. The acoustic mask is an effective measure to control this noise. The sound enclosure should be designed to ensure its airtightness for good sound insulation. In order to facilitate inspection and disassembly, the sound enclosure can be designed to be detachable, and the inspection door and observation window are reserved. At the same time, the heat dissipation problem of the unit should be considered, and the muffler should be installed at the inlet and outlet.

Fourth, the noise control of the gas tank

The air compressor continuously delivers the compressed gas to the gas storage tank, and the compressed air in the tank generates excitation vibration under the action of the air flow pulsation, which is accompanied by strong noise and simultaneously excites the vibration radiation noise of the casing. In addition to the sound insulation method, the noise can also be used to suspend the sound absorbing body in the gas storage tank, and the sound absorbing effect of the sound absorbing body is used to hinder the formation of standing waves in the tank, thereby achieving the purpose of sound absorption and noise reduction.

V. Comprehensive treatment of noise in air compressor stations

Many companies, usually with multiple compressors for production needs, have built air compressor stations. The noise of the compressor is very large. If a muffler is installed on the air inlet of each air compressor, not only the workload is large, but also the investment is large. Therefore, noise reduction measures such as sound absorption, sound insulation, and sound insulation can be taken in the station.

From the perspective of the effect and investment of noise control, such as the noise control measures in the air compressor station process design and civil construction, the investment can be reduced and better noise reduction effect can be obtained.
