DG horizontal multistage centrifugal pump

DG horizontal multistage pump--product overview

D/DG type horizontal multi-stage pump is a horizontal single-suction multi-stage segmented centrifugal pump. It adopts the hydraulic model of high-efficiency and energy-saving products recommended by the country. It has high efficiency, wide performance range, safe and stable operation, low noise, Long life, convenient installation and maintenance, etc. The product can be used to transport clear water without solid particles (abrasive), without suspended matter, or other liquids with physical and chemical properties similar to clear water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of the pump (or the material of the pump's flow-through parts), sealing form, and adding a cooling system. The allowable pressure at the pump inlet is less than 0.6MPa.

DG horizontal multistage pump-structure description

D/DG type horizontal multi-stage pump is mainly composed of four parts: stator, rotor, bearing and shaft seal:

1. The stator part of the D/DG horizontal multistage centrifugal pump is mainly composed of the suction section, the middle section, the discharge section and the guide vane. There are tension bolts to clamp each section to form a working room. To

2. The rotor part of D/DG horizontal multi-stage pump is mainly composed of shaft, impeller, balance disc and shaft sleeve. The axial force is balanced by the balance plate.

3. D/DG type horizontal multistage centrifugal pump bearings are mainly composed of bearing bodies, bearings and bearing glands, etc. The bearings are lubricated with grease or thin oil.

4. D/DG type horizontal multi-stage pump shaft seal adopts soft packing seal, which is mainly composed of sealing box body, packing and water retaining ring on the water inlet section and tail cover.

5. D/DG type horizontal multi-stage centrifugal pump The rotary pump is directly driven by the prime mover through the elastic coupling.
