Vibration Test System For Inverter Scroll Compressor Based On LabVIEW

Inverter scroll compressor, which is widely used air-conditioning, refrigeration and compression field in recent years as the research object, This topic describes the research of inverter scroll compressor in detail, makes a plan for the vibration test system needs and finishs a design of a complete design.In the hardware design process, for the small vibration characteristics of Inverter scroll compressor, This topic designed a vibration signal conditioning circuit, and achieved vibration of weak signal amplification and filtering in order to improve the accuracy of vibration signals. And changed the inadequate testing in the set speed and set working conditions, through the inverter and the PID algorithm of LabVIEW software programming successfully achieved the test conditions of variable speed and variable condition.In the software design process,With LabVIEW software advantages this issue used structured design and modular programming ideas, designed inverter scroll compressor vibration test system software architecture and achieved the collected vibration signals after the right speed scroll compressor.And in the absence of profound knowledge on the basis of the network, through the remote panel method, which is LabVIEW provides network communications nodes, achieved a remote control software control platform with quick and easy way.During the experiment, after the hardware debug link is right, the hardware and platform the software operating platform were combined to be a complete test platform. and through this platform obtained experimental data, these data were analysised by cepstrum analysis, correlation analysis theory, existing scroll compressors vibration data and motor fault diagnosis analysis, the problem of mechanical vibrations kind are identified prototype inverter scroll compressor main problems, the final solution is proposed in the last.
