Abstract:

The air compressor in unit 02 of the coal chemical project of Henan Zhongyuan Dahua Group Co., Ltd. runs by steam turbine, which has good energy saving, but there are problems such as abnormal vibration and high noise in normal production and operation. This paper introduces the on-line monitoring system of air compressor unit structure, vibration and other parameters, interlock protection program and spectrum analysis of 3500 system. The application of on-line vibration monitoring system and spectrum analysis technology in fault diagnosis of steam turbine is studied. Taking the air compressor and steam turbine set as the entry point to develop and demonstrate step by step; the results indicate that: shrink machine online monitoring system can timely find compressor unit in the production of abnormal condition occurred in the use of spectrum analyzer 3500 system on the vibration of the abnormal parts after data collection, through the spectrum, the axis trajectory and production process parameters and so on carries on the comprehensive analysis can effectively judge the fault mechanism of unit, thus provide unit operation optimization scheme.

Key words: turbine, process systems, spectrum analysis, measurement, optimization
