供水车间水源泵系我厂水系统的咽喉设备,其安全运行是全厂正常供水的首要保证。2~#水源泵型号24Sh-9A,额定流量为31601m~3/h,额定出口压力0.78MPa,电机功率780kW,工作介质为长江水,含砂量600mg/L,汛期高达1800mg/L。至1993年4月(累计运行31172h)检修时,发现泵体流道磨蚀冲刷出沟槽深度已达20～30mm。因此,计划1994年11月全厂停工大修时整体更新。但到1994年5月,
The water pump in the water supply workshop is the throat equipment of the water system in our factory. Its safe operation is the primary guarantee for the normal water supply in the whole plant. 2 ~ # water source pump model 24Sh-9A, rated flow 31601m ~ 3 / h, rated outlet pressure 0.78MPa, motor power 780kW, working medium for the Yangtze River water, sand 600mg / L, up to 1800mg / L in flood season. To April 1993 (cumulative run 31172h) overhaul, found that the erosion of the pump runner groove depth has reached 20 ~ 30mm. Therefore, it is planned that the whole plant will be updated as a whole during the overhaul of the whole plant in November 1994. However, by May 1994,
