1. This DG high pressure multistage water pump is a horizontal, single suction, multi stage centrifugal pump, the suction and outlet both vertical upward. Water suction, middle, discharge section, bearing housing and pump body are bolted into one strain, and select stages according to the pump head.
2. Rotor includes shaft, impeller, shaft sleeve, balance disk, and other parts. Axis parts are connected through the flat keys and the shaft nuts. The rotor is supported by the rotor bearings or sliding bearings or in both ends, the bearing does not bear any axial,axial force is balanced by the balance disc. Bearings lubricated with grease, sliding bearings lubricated with light oil, and oil ring lubrication, and cooled by circulating water.
3. Shaft seal in the form of two kinds, mechanical seals and packing seal. When use packing seal, the packing ring should be placed at the right location, the tightness of packing must be appropriate to the liquid oozing drop by drop. Various sealing elements are in a sealed chamber, the chamber must be filled with some water, as water seal, water cooled or water lubrication. At the seal there is reserved sleeve, to protect the shaft.
4. From the motor direction, the pump is clockwise rotation
