Investigation of performances of frequency convertible scroll compressor of natural gas

A frequency convertible scroll compressor was investigated for supplying natural gas to miniature gas-turbines. A test rig of gas supply system was set up and a testing and data gathering-analyzing system was developed for this scroll compressor in order to optimize its components and overall system. With the help of this system, the date gathered could be analyzed in detail and detailed operational conditions of such compressor could be obtained. It was shown by the data analysis that this frequency convertible scroll compressor exhibited high efficiency and low vibration. In the meantime, a service life test of 400 h was successfully completed for this system, showing the safety and reliability of the gas supply system by using the scroll compressor developed. The special design requirement was satisfied completely, so that this investigation provides a theoretical and experimental basis for application of this frequency convertible scroll compressor in the compression of natural gas.
