S-series single-stage double suction pump structural characteristics
S (SM, SF, SL) single-stage double suction pump is a new energy-saving replacement products, the pump performance advanced, stable operation, safe and reliable. Now to introduce the S-series single-stage double-suction structure in the open centrifugal pump. S series single-stage double-suction open centrifugal pump S-series single-stage double suction centrifugal pump in the open Structure S (SM, SF, SY) single-stage double suction pumps for horizontal installation, suction and Spit exports are below the pump shaft centerline, perpendicular to the axis of the pump, without dismantling the inlet and outlet pipes, remove the pump cover can remove the rotor parts, the pump mainly by the pump body, pump cover, impeller, seal ring, Bushings, bearings and other components, the pump body and the pump cover constitute the impeller studio, impeller axial force through the symmetrical layout of the blade balance. Bearings: Both ends of the pump for the rolling bearing support rotor components, with grease lubrication, the inlet diameter is too 700mm thin oil lubrication. S, SH type single-stage double-suction pumps in the pump inlet and outlet are below the axis of the pump, the horizontal direction and axis into a vertical position, the pump housing. In the open, maintenance without dismantling the water, the discharge pipe and The motor (or other prime mover) looks in the direction of the pump from the coupling and the pump rotates in the counter-clockwise direction. Such as the user's special order needs can be changed to clockwise rotation. S, SH-type single-stage double-suction pump to open the main pieces are: pump, pump cover, impeller, shaft, double suction seal ring, bushings, bearings and so on. In addition to the shaft material for high-quality carbon steel, the rest mostly made of cast iron. The pump body and the pump cover constitute the working chamber of the impeller. The inlet and outlet water flanges are provided with a tube screw hole for installing a vacuum gauge and a pressure gauge, and the lower part of the inlet and outlet water flanges is provided with a tube screw hole for discharging water. Impeller after static balance check, with the sleeve and the sleeve nut on both sides of its axial position can be adjusted by the sleeve nut, the axial force of the impeller using its symmetrical blade layout to achieve balance, there may be some left The remaining axial force is coaxial bearing endure. The pump shaft is supported by two single row radial ball bearings. The bearings are housed in the bearing body at both ends of the pump body. They are lubricated with butter. The double suction sealing ring is used to reduce water leakage from the pump pressure water chamber back to the suction water chamber. The pump is driven directly by the motor through the coupling. Shaft seal for the soft packing, in order to cool the lubrication seal chamber and prevent air leakage into the pump, there is a water seal between the packing, pump a small amount of high-pressure water flow through the water seal into the packing chamber from the water seal role.
