综采面支架液压系统的压力损失主要由支架主供液系统的压力损失和支架液压系统的压力损失组成。分析了支架主供液系统和支架液压系统,确定了各项参数,对两部分的压力损失进行理论与AMESim仿真分析,得出综采面支架液压系统的压力损失主要在关键阀上,减小关键阀压力损失对减小支架液压系统的压力损失有事半功倍的效果。 The pressure loss of the hydraulic system of the fully mechanized coal mining support system is mainly composed of the pressure loss of the main supply system of the support and the pressure loss of the hydraulic system of the support. After analyzing the parameters of the system and the hydraulic system of the support, the theoretical analysis and AMESim simulation analysis of the pressure loss of the two parts are carried out. The results show that the pressure loss of the hydraulic system of the support of the fully mechanized mining face is mainly on the key valve and decreases The key valve pressure loss can reduce the pressure loss of the hydraulic system of the bracket with a multiplier effect.
