我矿暗斜井提升系统建成投产于上世纪80年代,限于当时的历史条件,绞车电控系统采用的是继电器—接触器甩电阻系统,液压、润滑、电控、电机等全部为非防爆结构,且由于使用年限较长,绞车调绳离合器油缸、液压站、润滑系统等多处漏油,电控系统故障率高,工人维护劳动强度大。随着综
Mine mine inclined shaft hoist system put into operation in the 1980s, limited to the historical conditions at that time, winch electric control system uses a relay - contactor rejection resistance system, hydraulic, lubrication, electric control, all non-explosion-proof electrical machinery , And due to the long service life, winch tune rope clutch cylinder, hydraulic station, lubrication system and other oil spills, the high failure rate of electronic control systems, workers to maintain a large labor intensity. With the comprehensive
