Flood Drainage Double Suction Water Pump
1. The suction port and discharge port of the flood drainage double suction water pump centrifugal pump are both below the pump axis line. The horizontal direction is vertical to the axis, and the pump casing is opened in the middle. There is no need to disassemble the inlet and outlet pipes during maintenance The road and the motor (or other prime mover) are seen from the direction of the coupling to the pump, and the water pump rotates counterclockwise. It can also be changed to clockwise rotation according to the user's special order needs.
2.防洪排水的主要组件双苏ction water pump include: pump body, pump cover, impeller, shaft, double suction seal ring, shaft sleeve, bearing, etc. Except the shaft material is high-quality carbon steel, the rest is mostly made of cast iron. The pump body and the pump cover constitute the impeller's working room. The inlet and outlet flanges have pipe screw holes for installing vacuum gauges and pressure gauges, and the lower part of the inlet and outlet flanges has pipe screw holes for draining water. The impeller has been checked for static balance and fixed with a sleeve and sleeve nuts on both sides. Its axial position can be adjusted by the sleeve nut. The axial force of the impeller is balanced by the symmetrical arrangement of its blades. There may be some remaining The remaining axial force is borne by the bearing at the coaxial end.
3. The pump shaft is supported by two single-row radial ball bearings. The bearings are installed in the bearing bodies at both ends of the pump body. They are lubricated with butter. The double suction seal ring is used to reduce the water leakage from the pressure chamber of the pump back to the suction chamber. The water pump is directly driven by the motor through the coupling. The shaft seal is a soft packing seal, in order to cool and lubricate the sealed cavity and prevent air from leaking into the pump. There is a water sealing ring between the fillers, and a small amount of high-pressure water flows into the filler cavity through the water sealing pipe when the water pump is working to play a water sealing role.
