1. cavitation and its damage on the pump if the pump running noise and vibration, and is accompanied by a small flow, head low and insufficient output power and small phenomenon 80ZJ-42 slurry pumps, and sometimes does not work, when servicing this pump, it is often found near the edge of the blade at the front cover and the blade entry edge pitting or cellular state, but the parts appear badly worn, seriously cover the entire front and rear blades have this phenomenon of slag pump, even leaves and cover is worn, this is the destruction caused by the cavitation. Not only the performance of the pump cavitation decline 100ZJ-33 slurry pumps, noise and vibration, and shorten the life of the pump, the pump does not work serious. Therefore, in line characteristic calculation and pump selection work, be sure to make the tubing NPSH (ie effective NPSH) NPSHa larger than the pump NPSH (NPSH) r. 100ZJ-42 slurry pumps, slurry pumps, accessories (Figure) Ltd provided by the Shijiazhuang-send pump.
