1. cavitation and its damage on the pump if the pump noise and vibration during operation, and is accompanied by a small flow rate, head low and insufficient output power and small phenomena, and sometimes does not work, when servicing this pump, 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, even leaves and cover are worn, efficient slurry pump, which is the destruction caused by the cavitation. Routine maintenance edition 1) bearing pressure, the amount of water to meet the requirements, at any time to adjust (or replace) the tightness of packing, do not cause seal leakage of plasma. And replace the sleeve. 2) When replacing bearings, ZJ series slurry pump, we must ensure that the bearing assembly clean, clean lubricating oil pump runtime bearing temperature generally does not exceed 60- 65 ℃ is appropriate, slurry pumps, the maximum does not exceed 75 ℃ . 3) To ensure concentricity of the motor and pump, slurry pump tailings to ensure complete and correct coupling elastic cushion, should be replaced if damaged. 4) ensure that the pump components and piping systems installed correctly, solid and reliable. Slurry pumps, 150ZJ-I-A70, efficient slurry pump Co. sent by Shijiazhuang-pump. Slurry pumps, 150ZJ-I-A70, efficient slurry pump Pump Co., Ltd. Shijiazhuang Shi faction (www.shipaipump.com) this year introduced a new upgrade, the above picture is for reference only, please call or pictures on this page contact telephone number, to obtain the latest information, Contact: Manager Xu.
