Troubleshooting impeller wear faster journal reasons: high pressure pump head lower, packing dislocation, shaft and cover disagreements heart approach: Change is higher than the high-pressure pump mud pump head and change packing, conditioning concerted degree pump wear faster reasons: Construction case (large particles) difference, and recommended interval far, inlet pipe length approach: change the battlefield, add afterburner unit, shorten the length of the inlet pipe to reduce cavitation. Installation and disassembly sequence in reverse order of dry mortar tank Note: After the impeller fight fight tight cap, check the tank mortar flow gap between the impeller and pump body, this gap requires about 2mm. After installing the pump cover, check the clearance between the impeller and the pump cover (from the outlet of looking in), this gap should guarantee about 2mm dry mortar storage tank, mortar flow temperature medium tank with pump manufacturer, this clearance requirements around 2.5mm. The gap between the impeller and the pump fail to meet requirements, can be adjusted by shims between impeller and shaft sleeve. Pump cover and impeller mainly the gap between, can be adjusted by shims between the pump and the pump cover. 2 with pay impeller pump (inlet diameter> 125mm pumps) Hangzhou mortar flow tank, mortar flow tank production, Honda environmental protection (certified merchants) are provided by Xinxiang City Hongda energy saving equipment Limited.
