Testing Systerm Of Pump

The Pump is the most important draining installation of coal mining; its performance directly affects the security and efficiency of production in coal mining badly. To ensure that pump works normally, as it carries out performance detection, is very important. At present, in our country, the testing means of mineral pump is unity, and method is outmoded, the automatic level is not high, unable to meet the actual demands. Virtual Instruments is an apparatus that bases on the PC. Testing with the Virtual Instruments can adequately make use of the computer's advantage for data processing, which could fetch up the shortage of traditional testing. This paper studies through testing the thorough of requirement and present situation for the key parameters of mineral pump, lead into advanced Virtual Instruments technology the performance detection and analysis of mineral pump in. After synthesizing contrast Virtual Instruments 5 kinds of hardware form, found to finish structure simple and performance price high PC-DAQ model Virtual Instruments hardware platform. In this design, the test software is developed with object oriented programming thought and modular design method of standing independently. This system carries out the monitoring of mineral pump's key parameter, such as flow, head, power, efficiency and rotation rate. This testing system stocks with the functions such as signal collection and analysis, save and report generation in one body, and have realized the performance test of mineral pump integration and automation. The design has the advantages such as subprogram reapplication good, software maintenance convenience, conducted efficiency high etc.; with menu and dialogue box as interactive window, make operation friendly shortcut; with HTML language design webpage report, make test report be clear at a glance. With the simulation verification, it is proved that the instrument has reached design purpose to achieve the performance test of mineral pump.
