1.Horizontal water centrifugal pump housing (that is, pump body and pump cover) to form a pump studio. Impeller, shaft and rolling bearings, etc. for the pump rotor. The suspension bearing part supports the rotor of the pump, and the radial force and axial force of the rolling bearing are affected by the pump.
2.In order to balance the axial force of pump impeller, pump the most before and after is provided with a sealing ring, and a balance hole in the impeller hub, the axial force of pump impeller back some small, no sealing ring and balance hole.
3.Axial horizontal centrifugal pump sealing ring is composed of packing gland, packing ring and packing etc., to prevent air or a large number of Water Leakage. The impeller of the pump if the balance cavity and impeller with soft packing suction port as the impeller inlet liquid in the vacuum state, it is very easy to intake along the surface of the shaft sleeve, the packing ring through the pump cover hole is arranged in the packing chamber, the pump room pressure water to fill material for sealing ring. If there is no balance hole of the impeller of the pump, the liquid pressure on the back side of the impeller is greater than the atmospheric pressure, so there is no leakage problem, therefore, the packing ring can not be filled.
4.In order to avoid shaft wear, in the shaft through the packing chamber is equipped with protective sleeve. A quasi O type sealing ring between the shaft sleeve and the shaft, along with the surface to prevent intake or Water Leakage.
5.Pump transmission is through the extension of the elastic coupling and motor coupling, the rotation direction of the pump, from the driver to see, for the clockwise rotation.
