煤矿节能水力清管除垢技术的应用排水管路内壁沉积结垢是煤矿普遍存在的一个不可忽视的问题。它不仅可使排水管路管径缩小，输水断面减小，排水阻力增大，降低管网及排水系统效率，而且增加排水电耗。目前，新汶矿务局共有主排水泵房２８个，主排水管路７５条，总长度６０... Application of energy-saving hydraulic pipe cleaning technology in coal mines Drainage pipe wall deposition and scaling is a ubiquitous coal mine can not be ignored. The utility model not only can reduce the diameter of the drainage pipe, reduce the water transmission section, increase the drainage resistance, reduce the efficiency of the pipe network and the drainage system, and increase drainage electricity consumption. At present, Xinwen Mining Bureau has a total of 28 main drainage pumping stations, 75 main drainage lines, total length 60 ...
