Abstract:

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.
