矿用泵在使用过程中承受冲蚀、穴蚀和腐蚀水的磨蚀,这对水流过部份的零部件要产生各种影响,引起水力、圆盘或容积损失的增加,加剧断流和涡流作用,改变相对速度向量,亦即,最终将导致压头、效率、排量的降低,引起磨损故障,从而限定了泵的技术寿命。 Mining pumps are subject to erosion, cavitation and corrosive water erosion during use, which has various effects on the flow of water through parts, causing an increase in hydraulic, disk or volume losses, aggravating runoff and eddies The effect of changing the relative speed vector, ie, eventually resulting in a reduction in head, efficiency, displacement, causing wear failure, thus limiting the technical life of the pump.
