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 300ZJ -I-A100 slurry pumps, 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 the blades and the cover is worn, this is the destruction caused by the cavitation. This series of products designed for single-stage, single-suction centrifugal slurry pumps. Form of the structure is divided into horizontal (EZJ series) and vertical (EZJL series). Horizontal pumps outlet diameter divided by 350mm, 300mm, 250mm, 200mm, 150mm, 100mm, 80mm, 65mm, 50mm, 40mm and other specifications; each size diameter of the pump head according to the need for selection of different impeller diameter. ? di-fo ai ?? h color: # 333333; mso-font-kerning:? 0pt '> overall performance: wide performance range of the pump cavitation performance, high efficiency. Tandem technology can 80ZJ-I-A36 slurry pump, in order to meet the long-distance transport. There are a variety of metal wetted parts are available 300ZJ-I-A95 slurry pump, and increase the depth. Using a variety of speeds and various modifications manner, causing the pump to operate at optimum mining. Long life, high efficiency, to meet the many types of bad transport conditions. 100ZJ-I-A42 slurry pump, Shijiazhuang-school (certified), slurry by Shijiazhuang-Pump Co., Ltd. faction.
