液压支架立柱端盖拆装机是维修综采设备时用来拆装液压支架立柱端盖的专用工装设备,因其可显著减轻工人的劳动强度并提高工效得到广泛应用。 目前,较多机型是低速大扭矩马达直接驱动卡盘推移千斤顶推进立柱,定量泵节流调速的开式液压系统。该系统使用中发现马达低速运转时的稳定性很差,有时会出现爬行现象;由于马达的输出功率较大,采用效率低的开式节流调速系统,也 Hydraulic support column end cap disassembly machine is used to disassemble the hydraulic support column cover special equipment when maintenance of fully mechanized mining equipment, because it can significantly reduce the labor intensity and improve work efficiency has been widely used. At present, more models are low-speed large torque motor direct drive jack pushing the jack to promote the column, quantitative pump throttling speed open hydraulic system. The use of the system found that the motor at low speed stability is poor, and sometimes crawling phenomenon; due to the motor output power, using low efficiency of the open throttling speed control system, also
