Structure type :
QDG pump is a horizontal, single suction, multi-stage centrifugal pump. The inlet and outlet of the pump are vertically upward, and the tension screw connects the suction section, middle section and spitting section of the pump into one.
The pump rotor is composed of impeller, balance plate and other parts mounted on the shaft. The whole rotor is supported by sliding bearings at both ends of the pump shaft. The bearing is lubricated with lubricating oil and cooled with circulating water. The axial force of the rotor is balanced by the balance disc.
3. The shaft seal adopts packing seal or mechanical seal. A sealing function is arranged at both ends of the shaft, which is equipped with soft packing or mechanical seal. The water with certain pressure enters the sealing function to seal and cool. A replaceable sleeve is installed at the shaft seal to protect the pump shaft. The pump is directly driven by the motor through the elastic coupling. From the motor end, the pump rotates clockwise.
