Abstract:Aiming at the problem of starting noise in rotary vane compressor, a compressor system is tested, analyzed and improved. Firstly, the noise test platform is built for the test of the rotary vane compressor starting noise in a semi-anechoic chamber, and the starting mechanism of the compressor is analyzed; Then, measures to control the starting noise duration are proposed, and the control effects of different globe valves and clutch structures on the starting noise of the compressor are tested respectively; Finally, the control effect of different globe valves and clutch structure is verified by experiment on a real car. The result shows that the starting noise of rotary vane compressor is an inevitable inherent characteristic; Through the control method of compressor ball valve structure and clutch structure, the starting noise duration can be effectively shortened by 1~2 s.
