摘要
泵、阀、马达等组成的开式液压系统技术以其运行平稳、抗负载波动能力强而广泛适用于掘进机设备上,但系统复杂、占用空间大、元件多、可靠性不高,维护困难等问题一直是业界的难点,采用性能先进可靠的负载敏感、恒功率、恒压组合变量泵和负载敏感比例多路换向阀的掘进液压系统,有许多优越性。
Opening hydraulic system is composed of pump, valve and motor etc. and apply to roadheader abroad by the smoothly and the ability to unquiet load, but the system have more problems：complexity of system,large cubage, fallibility of parts and difficult to repair etc.. This machine display so much excellence include load - sensitive and constant voltage and constant pressure pump, on the side include the multi - access valve of sensitive to load.
