山东三山岛金矿IH100-65-315/75kW水泵的技术改造

针对-510 m、-333 m井下临时水泵房IH100-65-315/75KW水泵使用过程中出现的轴承使用寿命短、轴承箱轴承孔同轴度公差尺寸差和轴密封泄漏等问题，采取了相应的改造措施。试验对比研究表明，经过水泵技术改造后，仅在-510 m泵房的应用每年可节约电量5×104 kWh，年节约电费支出3万余元；通过安装DSF动密封填料后，由于水泵泄漏量减少，水泵排水量明显增大；水泵的技术改造，减轻了维修工作量，使备件消耗下降，提高了设备完好率和利用率，降低了故障率，为生产创造了良好的条件，改造效果明显。

The Technology Transformation of IH100-65-315/75kW Pump in Sanshandao Gold Mine,Shandong Province

In order to resolve the problems of short bearing life,bearing housing bearing hole concentricity tolerances and shaft seal leakage of the IH100-65-315/75kW pump,which is used in underground temporary pump rooms of-510 m and -333 m,appropriate transformation is done.The comparative study results show that after the transformation,only in -510 m pump room,we can save electricity 50 000 kWh/a,and have a savings of 3 million yuan.By installing DSF dynamic sealing filler,the pump displacement increases significantly due to the reduction of pump leakage.The transformation can not only reduce the maintenance workload,the parts consumption,and the failure rate,but also improve the availability and utilization rate,and create good conditions for the production.
