*Sturcture-High Pressure Centrifugal Boiler Feed Water Pump

Pump is supported by both ends, and casing portion is sectional. It connected with motor by flexible coupling. Viewing from the motor end, pump is in clockwise direction rotating. Refer to Fig. I for the structure of it.
 
1) Stator portion
Have suck-in section. middle-section, discharge section, guide vane, stuffing box etc., which connected by bolts
 
2)Rotor portion
Main parts includes shaft, impeller, balancing disk, shaft sleeve etc.
 
3)Bearing portion
Roller bearings or sliding bearings on both ends support whole rotor, bearings are lubricated with grease or 20# engine oil.
 
4)Cooling and seal of pump
Seals joint surface of suck-in, middle, and spitting section by molybdenum disulfide lubricating grease. Seals rotor and stator by ring, diffusor sleeve and packing. The packing should be proper and leak drop by drop. Forbid unload running. Change seal ring and diffusor sleeve if they damaged and influence pump. The changeable shaft sleeve near shaft seal can protect
pump shaft. Must have seal water if run. If medium temperature is above 80oC, fill cooling water to gland assembly and shaft seal cooling chamber. Cooled water and seal water should be clean water in normal degree. Cooled water pressure should be l.5~3Kg/cm2, seal water should be more than 0.5~1 Kg/cm2 of the seal chamber. The positions of cooling water pipe joints are different for various kind of water pumps. Please refer to construction drawing of pump for axial position, and refer to chart I for radial position.Shaft seals are classified as packing seal and mechanical seal. Seal water of packing seal is industrial water, with pressure of 2~3kg/cm2. The flushing water of mechanical seal is softened water, pressure must
higher 3kg/cm2 than inlet pressure.
