The control of air compressor noise mainly adopts three aspects: muffler, silencing tunnel and sound insulation technology:
Install the muffler
The main noise source is the intake and exhaust ports, and appropriate intake and exhaust mufflers should be selected. The frequency spectrum of air compressor intake noise presents low-frequency characteristics, and the intake muffler should use a resistant structure or an impedance composite structure based on individual and resistance. The exhaust air pressure of the air compressor is large and the air flow speed is high. A small hole muffler should be used at the air compressor exhaust port.
Set up silencing tunnel
The underground or semi-underground tunnel of the anechoic tunnel, the tunnel wall is made of bricks with good sound absorption. Connect the intake pipe of the air compressor to the muffler tunnel so that the air enters the air compressor through the muffler tunnel. The use of muffler tunnels can greatly reduce the intake noise of the air compressor, and the service life is longer than that of general mufflers.
Building a sound enclosure
After installing mufflers or silencing tunnels at the intake and exhaust ports of the air compressor, the airflow noise can be reduced to below 80db(a), but the mechanical noise and motor noise of the air compressor are still very high, so it should be used in the air compressor. Install a sound insulation cover on the unit of the machine. Suspended space acoustic body: At the Foshan Linggefeng air compressor station, the tall and empty factory buildings have heavy reverberation. If the sound absorber is dispersed and suspended on the roof of the factory building, the noise of the factory building can be reduced by 3-10db(a), and the reverberation time can be reduced by 5-10s.
Routine maintenance includes checking the temperature, the amount of oil, the heat dissipation of the heat pipe radiator, the amount of operating current, the noise and vibration, the size of the labor, etc. and should be checked on time. The operating temperature of the air compressor should be maintained between 5 and 40°C. Indoor air should be naturally ventilated to maintain dryness and coolness. Do not place it in the opened area.Zhejiang Zhilun Mechanical & Electrical Co., Ltd is located in Hengjie Town, Luqiao District, Taizhou City far from Taizhou Airport is only 3KM, as a professional China Rotary Screw Air Compressors Manufacturers and wholesale Oil free rotary screw air compressor factory.Our company has advanced production equipment and well familiar with the process of the batch manufacturing has high precision measuring instruments and high efficiency of automatic assembly line ensure the quality and quantity of the product, specializing in the Research and Development, Manufacturing and sales of the wholesale Oil free rotary screw air compressor.
