Purchase skills submersible pumps, sewage pump selection, selection of submersible pumps, sewage pump selection within a building used by the drain pump diving sewage pumps, liquid drainage pumps, vertical sewage pumps and horizontal sewage pumps. Because space within the building is generally small, little displacement, drainage pump can be given priority submersible sewage pumps and drainage pumps liquid pumps, which are generally lower liquid sewage pump in important places; vertical sewage pumps and horizontal sewage pumps required to set isolated basis, self-filling type absorption, and take up some space, so less use in construction by the fire pump motor and pump two parts, the motor for the Y-phase asynchronous motor chopped sewage pump, fire pumps and motors using coupling connection, the overall rigid connection, so when used without correction. Fire pumps from the stator portion and the rotor parts. The stator part by the water pump, middle, guide vanes, the water segment, seals and other parts. To prevent the stator wear, with sealing ring, balancing sets and other regulators to pump stator, replacement of worn parts availability. Part of a rotor shaft, impeller, balance drum and other components. The lower end of the impeller rotor, the upper angular contact ball bearings, axial force most of the pump by a balance drum to bear the remaining small portion of residual axial force by the angular contact ball bearings to bear. Combined with surface water, middle and outlet sections of a paper pad with bolts tightened to seal. However, some well-known manufacturers use the rubber O-rings or metal O-ring to achieve sealing effect, as far as I know the rubber O-rings and metal O-rings Atlantic Pumps fire pump is used. Strictly speaking, with O-rings instead of paper pad is a trend, paper pad technology has lagged too far behind, not easy to maintain, because the paper pad almost all single-use products, O-rings can be used repeatedly.
