Fire pump motor and pump by two parts, motors, three-phase asynchronous motors for Y stainless steel sewage pumps, fire pumps and motors are connected to the coupling, the overall connection is rigid stainless steel multi-stage pump, so when used without correction. Fire pump stator and rotor parts section. In part by the water pump stator, middle, guide vanes, the water segment, seals and other parts. To prevent the stator wear, with sealing rings, sets, and so on balance stator, available spare parts to replace worn. Part of a rotor shaft, impeller, and other components to balance the drum. The lower end of the impeller rotor upper angular contact ball bearings, axial force most of the balance drum pump borne by the remaining small portion of residual axial force by angular contact ball bearings to bear. Combination of surface water, middle and outlet sections are paper pad by bolts tightened to seal. But some well-known manufacturers use a rubber O-ring or metal O-ring to achieve sealing effect, as far as I know the rubber O-rings and metal O-ring Atlantic pump fire pump is used. Strictly speaking with O-rings instead of paper pad is a trend, paper pad technology has been too far behind, and not easy to maintain, because almost all disposable pad of paper products, O-rings can be used repeatedly. The basic components of a high-speed centrifugal impeller rotating and stationary snail-shaped casing. Has several (usually 4 to 12) after the curved blade impeller shaft is secured to the pipe on the booster pump and the shaft driven by a motor with a high speed rotation. The impeller is directly acting on the components of the liquid pump, means for energizing the centrifugal pump. The center of the pump casing suction port is connected to the suction pipe, the bottom end of the suction pipe is provided with a one-way valve. Regulating valve outlet and equipped with exhaust pipe connected to the side next to the pump casing. West Baoquan | stainless steel sewage pump | Yinchuan Baoquan water pump provided by the West.
