Testing System of Hydraulic Head of Mine Pump Based on LabVIEW

The operation state of mine pump must be tested periodically because its failure rate is very high. But the existing testing systems have some defects. So, a testing system is developed based on the virtual instrument technology for testing the hydraulic head which was a key parameter used to describe the operation state of the mine pump. In this new testing system, all meters used in the traditional testing system were replaced by testing software. Multiple physical signals can be acquired simultaneously, and all the acquired data can be processed by computer. On the other hand, the ultrasonic sensor is used in this system, so the mine pump can be tested without stopping working. It is known from actual testing that the testing error is less than 3 percent, and the testing efficiency is enhanced to a great extent.
