CDL200-30-A multi-stage pump structure diagram
Multistage pump is mainly composed of four parts: stator, rotor, bearing and shaft seal:
1. The stator part of the multi-stage pump is mainly composed of the suction section, the middle section, the discharge section and the guide vane, etc., with tension bolts to clamp each section to form a working room. The D-type pump generally sucks in horizontally and discharges vertically upward; when it is used for water injection in oil fields, the inlet and outlet of the pump are vertically upward. The outlet and inlet of the DG multi-stage pump are vertically upward.
2. The rotor part of the multi-stage pump is mainly composed of shaft, impeller, balance disc and shaft sleeve. The axial force is balanced by the balance plate.
3. Multi-stage pump bearings are mainly composed of bearing bodies, bearings and bearing glands. The bearings are lubricated with grease or thin oil.
4. The shaft seal of the multi-stage pump adopts a soft packing seal, which is mainly composed of the sealing box body, packing and water retaining ring on the water inlet section and the tail cover. D type pump water seal water comes from the pressure water in the pump. The sealing water of DG pump comes from external water supply.
