Faults and solutions Cause and Solution 1, no water pump suction pressure gauge pointer jumping insufficient amount of water injected into the bottom of the valve or pipe plug leaks produced, taken to the appropriate water pump, then try to check the leak site operation. If still Sheung Shui, you should check whether the bottom valve blockage, high water absorption exceeds a predetermined height. Impeller outlet and whether the blockage. 2, the flow is lower than the original value of the pump blockage within the seal ring excessive wear, and the impeller clearance exceeds the specified value or less speed pump operation, check the related replacement parts. 3, the pump power consumption is too large, the driving force overloaded with too tight packing, stuffing fever phenomenon, or because the water pump impeller wear and increase the reason, you should immediately adjust packing 4B15 centrifugal impeller, impeller replacement. 4, operation noise and other anomalies, not even tap water too much resistance in the suction pipe, inhaled air infiltration at. Or the delivery of the liquid temperature is too high. Check the suction pipe and bottom valve failure, to lower the temperature of the delivered liquid. 5, pump vibration, overheating of the pump shaft bearings and motor shaft is not the same a center line, bearing the body of oil, should immediately stop the pump and motor shaft centerline to adjust the concentricity, and clean the bearing body 4B15A centrifugal pump manufacturers, replace butter. Inflow direction impeller centrifugal, axial and mixed flow pumps are all axial, the differences between them in different impeller out of its flow direction. The streams exit centrifugal impeller in a radial plane perpendicular to the axis of the pump. A single-stage pump impeller pump installed only a single stage pump. Rotor support their way, will this pump into cantilever and both ends supporting categories. (A) the design and production of our cantilever pumps IS pump (Figure 1-1) shall be a single-stage single suction horizontal centrifugal pump. Its impeller 5 by the impeller nut 2 3 washers peace bond fixed at the left end of the shaft 12. The other end of the pump shaft to the coupling means, in order to achieve dynamic drag. In order to prevent the pump liquid along the shaft piercing the gap at the pump casing leak in the gap are equipped with shaft seal. IS pump seal is used in packing style, which consists of the sleeve 7, 8 and gland packing rings 10 and other components. When the pump, the pump shaft with two single row radial ball bearings supporting the rotation, so as to drive the pump in the pump impeller and pump cover 6 composed of a rotation. Because the pump shaft support bearings are located on both the right section of the shaft, the shaft mounted in the left section of the impeller overhang liberal state, so put this pump has a cantilevered structure called a cantilever pumps. 4B15 centrifugal impeller | centrifugal pumps | water pump impeller by Anguo Shi Yuan Pump Company.
