矿井运输机液压控制系统元器件选型设计

Selection and design of components for hydraulic control system of mine transporter

为解决马脊梁煤矿运输机工作过程中遭受冲击、皮带跑偏、煤尘严重等问题,对该矿运输机液压控制系统元器件进行选型设计,介绍了液压控制系统工作原理,分别选型设计了液压控制系统的电机、液压泵、液压缸、电磁比例阀、溢流阀、电磁换向阀、蓄能器等元器件。矿井运输机在液压智能自动化综合控制下,减缓了冲击压力,减少了煤尘,修正了皮带偏移,达到了设计目的。

In order to solve the problems of impact,belt deviation and serious coal dust during the working process of the Majiliang Mine transporter,the selection and design of the hydraulic control system components of the mine transporter,and the working principle of the hydraulic control system were introduced.The motor,hydraulic pump,hydraulic cylinder,electromagnetic proportional valve,relief valve,electromagnetic reversing valve,accumulator and other components of the hydraulic control system were selected and designed.Under the integrated control of hydraulic intelligent automation,the mine transporter slowed down the impact pressure,reduced the coal dust,corrected the belt offset,and achieved the design goal.
