适应液压支架动作的稳压供液技术研究
Research on stabilized pressure hydraulic fluid supply technology adapted to hydraulic support action
摘要
Abstract
In order to improve ability of hydraulic support following shearer in working face,coupling relationship among support action velocity,hydraulic system pressure and flow rate of hydraulic fluid supply was revealed by theory analysis of support hydraulic fluid supply process.Simulation model of hydraulic system on working face was established and correctness of the model was verified.Effect of hydraulic system pressure and flow rate on support action velocity was analyzed,and a stabilized pressure hydraulic fluid supply technology adapted to support action was proposed.The technology takes support action type and hydraulic system pressure limitation as criterion,and realizes slow and steady changing process of hydraulic system pressure with slight rise during support action by adjusting flow rate,so as to improve support action velocity.The technology was tested by use of multi-pump and multi-frequency hydraulic fluid supply system,and validity of the technology was verified.关键词
