stainless steel high pressure multistage water pump structure

 

 

For this series horizontal multistage Centrifugal Pump, both ends of it are supported, the casing portion is in a sectional form. it is connected to and actuated by a motor via a resilient clutch and the rotating direction of it. viewing from the actuating end. is clockwise. Refer to Fig. I for the structure of it.

Stator portion
Consists of suck-in section. middle-section, spitting section, guide vane, packing etc., which are linked together with a take-up bolt. with both suck-in and spitting mouths vertically upward.

Rotor portion
Consists of a shaft, impeller, balancing disk, muff etc. Parts.

Bearing portion
The whole rotor is supported by the roller bearings or
sliding bearings on both ends of the shaft and the bearings are lubricated with grease or 20# engin oil.

Cooling and seal of pump
The joint-part between suction section, intermediate section and discharge section with be coated with molybdenum disulfide lubricating grease as seal. Rotor and fixed parts will be sealed by seal ring, guide-vane jacket and packing. The packing tensile degree of shaft seal should be proper and seep should be feasible dip by dip Unload run should be forbid. The seal ring and guide vane jacket should be replaced if they are too worn to be used any more and even do harm to pump work. There is spare shaft sleeve near shaft seal to protect shaft of pump.

 

1) Water supply and discharge in high-rise buildings
2) Fire water supply in constructions
3) Water supply and discharge in factories and mines
4) Long distance delivery
5) Cyclic pressurization in production
