How to deal with the noise reduction measures of screw air compressor?

　　> screw air compressorThe most complete selection scheme and noise reduction measures, screw air compressor should use computer software for digital design, which can meet the requirements of personalized customization. The finishing of the screw rotor, body, bearing seat and other main parts of the screw air compressor, as well as the assembly of the screw host, should be carried out in a dust-free constant temperature and humidity environment. The final process of meshing surface processing of screw rotor must adopt a grinding process to ensure the stability of product quality and performance. Necessary testing equipment should be equipped with inspection and testing capabilities in terms of material composition, metallographic structure, mechanical properties, key dimensions and shape and position tolerances. There should be a special place for a semi-anechoic chamber to detect noise, and the semi-anechoic chamber should comply with the provisions of GB 6882 and JJF 1147. How about Zhigao screw air compressor, now follow the editor of Hunan Ruisheng Electromechanical Equipment to take a look.
　　
　　Performance requirements: When the first-stage suction temperature is 40 °C, the cooling water inlet water temperature is less than or equal to 30 °C and the exhaust pressure is the nominal value, the exhaust temperature should not exceed 110 °C, but the minimum temperature of the compressed air at all levels should not be lower than its dew point temperature (see JB/T 6430 Appendix A). In the case of an aftercooler, the exhaust temperature of its water-cooled air compressor unit should not exceed 40 °C. The actual volumetric flow of the screw air compressor under the specified working conditions should not be less than 95% of the nominal volumetric flow. The lubricating oil consumed by the screw air compressor per cubic meter of volume flow is not more than 10mg. The air cavity of the main engine pressure part of the screw air compressor should be hydrostatic test at a pressure not less than 1.5 times the rated exhaust pressure, and no leakage should occur for 30min. When the screw air compressor is equipped with a gearbox, its box body should be leakage test with kerosene, which lasts 2h, and there must be no leakage. The pressure vessel of the screw air compressor should comply with the provisions of GB 150 and TSG R0004 (or TSG R0003), of which the steel shell and tube heat exchanger should comply with the provisions of GB 151, and the NB/T 47006 aluminum plate-fin heat exchanger should comply with the provisions of NB/T 47006. The gray iron castings of the screw air compressor should comply with the provisions of JB/T 6431, and the ductile iron castings should comply with the provisions of JB/T 9104. The forgings of the screw air compressor should comply with the provisions of JB/T 6908. The outer circle of the rotor, profile, cogging groove, and the surface of each main journal shall not have cracks, cold partitions, shrinkage, porous inclusions and other defects affecting the quality, and there shall be no depressions, burrs and bumps on the friction surface.
　　
　　The quality inspection of gear materials and heat treatment should comply with the provisions of GB/T 3480.5. Its gear accuracy should not be lower than the 6-level requirements specified in GB/T 10095.2. The rotor should be balanced test, and its balance accuracy level should not be lower than G6.3. The rotor should be assembled in a dust-free and constant temperature environment. Other technical requirements, the suction port of the screw air compressor should be equipped with an air filter (filter) in accordance with the provisions of GB/T 14295. The screw air compressor should be equipped with at least the following automatic protection devices, and when any of them occur, the unit should be able to alarm or automatically shut down, and give corresponding instructions: exhaust pressure exceeded limit; Exhaust temperature exceeding the limit; motor overload; Phase sequence protection.
