Product Overview S-type single-stage double suction pump shell open centrifugal pump for the shaft to send water or other physical and chemical properties similar to water used. The temperature of liquid to be transported shall not exceed 80 ℃. For factories, mines, urban water supply, power plants, farmland irrigation and drainage and various water conservancy projects. Structure Description The pump inlet and outlet are below the axis of the pump, with the axis of the horizontal was horizontal, the pump shell open, without the need to dismantle the access to the water pipeline and the motor. Viewed from the coupling to the pump, the pump rotates clockwise (according to user needs can also be changed to counterclockwise rotation). The main pump parts are: pump body, pump cover, impeller, shaft, double suction seal ring, sleeve and so on. In addition to the shaft material for high-quality carbon steel, the rest mostly made of cast iron. Pump and pump cover constitute the studio impeller. In the inlet flange, the system has installed vacuum gauge and pressure gauge pipe screw holes. In and out of the flange of the water system, the system has a drain pipe screw. After the static balance of the impeller. With the sleeve and sleeve nuts on both sides of the shaft, 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, and some residual axial force may be absorbed by the shaft-end bearing. The pump shaft is supported by two single row radial ball bearings. Bearing installed in the bearing body, mounted on both ends of the pump body, lubricated with butter. Double suction seal ring to reduce leakage at pump impeller. The pump is driven directly by the motor via a flexible cylindrical pin coupling and, if necessary, by an internal combustion engine. Shaft seal for the soft packing. In order to prevent the air from entering the pump and cooling and lubricating the seal chamber, a packing ring is arranged between the packing materials. A small amount of high-pressure water flows in the pump and flows into the packing cavity through the trapezoidal groove which is opened in the pump cover.
