★ Cause: pump with diesel engine (or motor) different, unbalanced impellers, bearings damage;
★ Solution: regulation of leaf rotation concentricity, balance test, replace the bearing.
Pumps water slow
★ Reasons: front liners with the impeller gap, water pipes do not seal air, empty;
★ Solution: adjustment, adjust the water pipes, installation of vacuum devices.
Pump does not suction
★ Reasons: pouring water, pump enough air it cannot discharge, suction pipe leakage, the former liner with the impeller gap;
★ Original solution: continue pouring water, check whether the pipeline leak, adjust the clearance between impeller and front liners.
Low pressure and flow
★ Reasons: there is air in the pump, the impeller and the former clearance of the lining, clutch close tightly, or liner wear of the impeller;
★ Solution: emptying the pump gas, adjust the clearance adjustment clutch friction plate clearance, replacing the impeller or liner.
