为实现绿色开采,以掩护式支架为实例,用插装阀设计了一种新型液压系统。将支架控制阀的出口同乳化液泵站的供油管相连,将大流量安全阀的出口同乳化液箱直接相连,实现了乳化液资源的全部回收及恒阻阶段释放出的高压乳化液介质及所含有能量的再利用。通过采用插装式大流量安全阀,提高了液压支架在顶板周期来压时的工作安全性。该种支架的液压系统简单、可靠性高、能耗低,其设计思想可应用到其他架型的液压支架,推广应用后可取得明显的节能效果和社会效益。
In order to realize the green mining, a new type of hydraulic system has been designed by using the cartridge valve as an example. The outlet of the bracket control valve is connected with the oil supply pipe of the emulsion pump station and the outlet of the large flow safety valve is directly connected with the emulsion tank to realize the complete recovery of the emulsion liquid and the high pressure emulsion medium released from the constant-resistance stage And the energy contained in the reuse. Through the use of plug-in large-flow safety valve to improve the hydraulic support to the top of the cycle to work pressure safety. The hydraulic system of the bracket is simple, high reliability and low energy consumption, and its design idea can be applied to the hydraulic support of other frame types. After being popularized and applied, obvious energy-saving effects and social benefits can be obtained.
