The Design of the Measuring and Controlling System of the High Power Pump Performance Test-Bed Based on Virtual Instrument Technique

Abstract

To satisfy the performance test of the high power hydraulic pump, a test-bed is developed in this paper. The parameters, the sign of the control and the data of the state are concluded. The test-bed employs the virtual instrument technique and PXI bus structure as well as M series data acquisition apparatus, it can measure the important performance parameters, such as pressure, flow, torque, speed and temperature; then we deal with and analysis these data. During the testing procedure it can realize automatic control, such as regulating the flow, pressure and so on. During the measuring and controlling, we can also monitor the state of the test-bed and give an alarm, such as over temperature or pressure.
