对于地下开采的矿山企业来说,矿井主排水设备是矿山的主要用电设备之一,排水电费在单位矿石成本中所占的比例达到30%～40%。目前矿井主排水泵多采用MD单吸多级耐磨式离心泵,该水泵结构简单,质量轻,材料耗用较少,对基础要求不高,传动结构简单,易安装,输送悬浮液体能力较强,管理方便,工作可靠,因此广泛用于煤矿井下排水作业。但传统泵型采用特别“娇嫩”的平衡轴向力装置
For underground mining companies, the mine main drainage equipment is one of the main power equipment in the mine, drainage electricity costs in the unit cost of ore accounted for 30% to 40%. At present, the main drainage pump used multi-level multi-stage MD single-suction wear-resistant centrifugal pump, the pump structure is simple, light weight, less material consumption, less demanding on the foundation, the transmission structure is simple, easy to install, Strong, easy management, reliable work, it is widely used in coal mine drainage operations. But the traditional pump uses a special “delicate ” balance axial force device
