Compressor noise vibration testing system and method

Abstract

The invention relates to a compressor noise vibration testing system and method, and belongs to the technical field of compressors. The system comprises an air suction pressure tank and an exhaust pressure tank, and a pressure adjustment compressor and a to-be-tested compressor are connected between the air suction pressure tank and the exhaust pressure tank in parallel. The air suction pressure tank communicates with the exhaust pressure tank, a pressure balance valve is arranged between the air suction pressure tank and the exhaust pressure tank, the air suction pressure tank is connected with a refrigerant filling valve, and a stop valve is arranged on a pipeline for connecting the to-be-tested compressor with the air suction pressure tank and the exhaust pressure tank. The system is easy to operate and low in cost, noise vibration of the compressor can be rapidly tested, noise vibration effects under different design schemes are compared, the development period of the compressor isgreatly shortened, and the design cost of the compressor is reduced.

Description

Technical field[0001]The present disclosure belongs to the technical field of compressors, and specifically relates to a compressor noise and vibration testing system and method.Background technique[0002]The statements here only provide background art related to the present disclosure, and do not necessarily constitute prior art.[0003]With the improvement of the quality of life of users, the requirements for the experience of the refrigerator are getting higher and higher, which requires the sound quality of the refrigerator to be better and better. As the core component of the refrigerator, the noise characteristics of the compressor directly determine the overall level of the refrigerator. Therefore, each compressor manufacturer has continuously optimized and improved the noise and carried out a series of program tests.[0004]The inventor found that the current compressor noise test is carried out in accordance with the regulations in GB / T 9098-2008, and the required test environme...

AI Technical Summary

Problems solved by technology

[0004] The inventor found that the current compressor noise test is carried out in accordance with the regulations in GB / T 9098-2008, and the required test environment complies with GB / T4214.1-2000, and the cost of establishing a standard anechoic chamber is very high, and the recommended system Complicated operation is difficult. It takes 2-3 hours to test a R600a compressor, and the information on the market is changing rapidly. Once there is any bad noise problem reported in the market, it is necessary to respond quickly and come up with a solution. At this time, designers often come up with many kinds The scheme needs to be verified, and one scheme is verified for 3 hours. Suppose there are 5 schemes, and each scheme prepares 7 prototypes to illustrate the validity of the data. In this way, 35 sets of data need to be tested, 105h
