Abstract

Ratio power is one of the important performance parameters of compressor. The paper researched the compressor automatic test technology based on Virtual Instrument and then designed a convenient and high efficiency compressor ratio power tester with additional condition protection function applied in industry field. In the paper, a test scheme with PXI bus hardware and LabVIEW software was proposed. Then, based on research of vibration signal process method, realization arithmetic of automatic computational parameters tables search and theory of wavelet packet frequency band divided energy, an intelligent ratio power tester was introduced in detail. The instrument can monitor compressor running condition before or in the process of testing the value of ratio power, obtain each relate tested parameter automatically and show change trend, compute values of multi-type compressor ratio powers with automatic tables search and also give the compressor performance estimate results. The testing field running results with a water-cooling two level compressor shows that the tester has exact and fast calculation and has virtues of high efficiency, reliable performance and convenient use.
