Research On The Performance Test System Of Equipment Of Mining Hydraulic Support

Mining hydraulic support and emulsion pump have been the key device of hydraulic support for the fully mechanized face, the efficient and safe running of them has been closely related to economic benefit of coal mine and the safety of miners. With the rapid development of computer technology, modern intelligent detection technology and advanced virtual instrument technology, the use of which has an important meaningful to research the performance test system of equipment of mining hydraulic support.This paper mainly has taken the two column shield hydraulic support and horizontal five plunger reciprocating emulsion pump as the research object, taken the relevant provisions of the coal industry standard MT312-2000 on the performance detection of mining hydraulic support and the relevant provisions of MT /T188.2-2000 on the performance detection of emulsion pump as the basis, and determined the main parameters and their test methods of the performance test system of equipment of mining hydraulic support. According to the characteristics of test parameters and the requirements of test methods for the test system, this paper has constructed the hardware of the performance test system of equipment of mining hydraulic support and determined its overall structure, finished the selection of sensors, data acquisition card, computer, and the design of signal conditioning circuit. Through analyzing the function demand of the performance test system of equipment of mining hydraulic support, this paper has determined the overall structure of the performance test system software of equipment of mining hydraulic support. This paper has used the advanced virtual instrument technology, based on the LabVIEW2011 software,used the modular programming method and developed a performance test system analysis software of equipment of mining hydraulic support, and the software has set data acquisition, data processing, data storage, data query, report generation as a whole.This paper has built the experimental platform of the performance test system of equipment of mining hydraulic support and implemented the performance analysis and experimental verification for the performance test system. The experimental results have showed that the test system can realize the performance detection of the main parameters of mining hydraulic support and emulsion pump, have convenient operation and good performance, and be able to meet the needs of the production of coal mine.
