摘　　要：MG2×125/560采煤机适用于薄煤层开采,近年来随着机组过度的服役,以及产品的更新换代,因齿轮泵全局短缺,配件无法得到保证。为了解决调高系统的事故频发问题,决定对其进行改造,把MG250/591采煤机调高泵更换在MG2×125/560采煤机机组。通过实验模拟与现场使用,证明改造技术切实可行,能够很好地进行摇臂升降。同时,改造后的调高系统能够节省设备费、增加煤炭产值、减少停工损失等费用共计约843 250元,具有良好的社会效应和明显的经济效益。MG2 × 125/560 shearer for thin seam mining in recent years with the unit over the service,as well as upgrading the product,due to the global shortage of gear pumps,fittings can not be guaranteed.In order to solve the frequent accidents increase system determines its transformation,the MG 250/591 Shearer pump replacement MG2 × 125/560 Shearer unit.Through the use of simulation and field experiments proved feasible transformation technology can be very good arm movements.Meanwhile,after the transformation of the system increases,the device can save costs,increase coal output,reduce downtime losses and other expenses totaling about 843,250 yuan.Has a good social effect and significant economic benefits.
