摘要
由于煤矿井下地质条件复杂,造成液压支架在支护时所需供液压力波动较大,进而导致乳化液泵经常损坏和电机耗电量高等问题。本文研究的综采工作面液压支架恒压供液自动控制系统能够保证供液压力的稳定性,并有效节约电能,延长泵站的使用寿命,满足煤矿对安全生产和节能的要求。
Complex geological structure leads to obvious fluctuation of fluid feeding pressure required for hydraulic supports,which eventually causes frequent breakdown of emulsion pump and high energy consumption of motor.The fluid feeding system under constant pressure discussed in this paper could ensure the consistency of fluid feeding,reduce the electrical energy consumption and prolong the life of pump station,meeting the requirements for safe production and energy conversation.
