隔膜泵在某矿山尾矿输送工程中的应用

Application of diaphragm pumps to tailings transportation in a mine

长距离尾矿输送是针对不宜就近建立尾矿库的矿山提出的尾矿输送解决方案。通过对矿山尾矿矿浆流量和输送扬程的计算,对比分析了柱塞泵和隔膜泵2种尾矿输送设备在投资、运行、维修等方面的成本,综合考虑矿山服务年限,隔膜泵总费用优于柱塞泵,因此选用隔膜泵作为尾矿输送设备。实际应用表明:隔膜泵在尾矿输送中具有较好的社会效益和经济效益,节约运行费用约30%。

Long-distance transportation of tailings is a solution put forward to the mines where tailings ponds are not fit to be established nearby.The diaphragm pump is decided for tailings transportation because of lower cost than the piston pump.Based on the calculation of tailings slurry flow and transportation distance in a mine,the cost is decided because the total cost of diaphragm pump is lower than piston pump by comparing the costs concerning investment,operation and maintenance of the diaphragm pump and piston pump,and comprehensive consideration of mine service life.The application shows that the diaphragm pump has better social and economic benefits in tailings transportation and saves operation costs by 30%.
