摘要
TZMX75型钻装机是对煤矿井下"双突"掘进工作面而设计的,集瓦斯探放、物料装运于一体的高效新型多功能钻装设备。该机在井下钻孔、装运、行走调动均是由一个液压泵站提供动力源,因此其液压控制系统性能的优劣直接影响到整机的性能,该机型液压泵采用恒功率、压力切断、负载敏感液压控制系统,其控制阀组采用负载敏感比例多路换向阀。
TZMX75 type drilling machine of coal mine ＂double outburst in heading face of＂ design, set gas exploration, shipment of materials placed in one of the efficient multifunctional drilling equipment. The machine downhole in a borehole,shipment, walking mobility is a hydraulic pump to supply the power source,the hydraulic control system performance directly affects the whole performance, the aircraft hydraulic pump with constant power, pressure,cut off load sensing hydraulic control system,the control valve group used load-sensitive proportional directional valve.
