抽水蓄能机组双向推力轴承试验数据检测分析系统

The Data Acquisition and Analysis System for the Bi-directional Thrust Bearing Test of Pumped-storage Hydro-unit

为实现抽水蓄能机组双向推力轴承性能试验,获取试验数据,开发研制了推力轴承试验数据检测分析系统。硬件部分应用了无线动态数据采集系统和采集静态数据的VXI总线数采系统;软件部分在MATLAB平台上开发了试验数据实时在线分析软件。试验结果证明本系统数据测量准确、试验结果可以用图形实时显示,完全适应双向推力轴承试验的要求。

To realize the test of bi-directional thrust bearing of pumped-storage hydro-unit and to achieve the test data, the data acquisition and analysis system for the Bi-directional thrust bearing test was developed. System of wireless dynamic data collection and the system of the VXI bus of the static data collection were applied in hardware of the system. In the system the real-time analysis software based on MATLAB is developed. Test results have proved that the data measured by the system are precise, Test results can be displayed with the graph in real time and the test and analysis system meets the requirement of the test of bi-directional thrust bearing.
