S, SH type single-stage double suction pump main parts: pump, pump cover, impeller, shaft, double suction seal ring and sleeve bearings, etc.. In addition to the shaft material for high quality carbon steel, the rest is made of cast iron.
Pump impeller and pump cover composition of the studio, in and out water flange is provided with mounting Guan Luokong vacuum gauge and pressure gauge, import and water flange of the lower part is provided with a water drain pipe holes.
Impeller through the static equilibrium calibration and fixed by the sleeve and the sides of the sleeve nut and its axial position can be adjusted through the sleeve nut, the axial force of the impeller using the symmetrical arrangement of the blades reach equilibrium, may have some surplus axial force is coaxial end bearing.
Pump shaft is supported by two single row radial ball bearing bearings mounted in the bearing body on both ends of the pump body, grease, double suction seal ring is used to reduce the water pressure water leakage from water chamber back to the suction chamber.
The pump is driven directly by the motor through the coupling.
Seal soft packing seal, to cool and lubricate the seal chamber and to prevent air leakage into the pump, in between the packing water seal ring, while the pump is working a small amount of high pressure water through a water seal pipe into packing cavity seal role.
