Stable Running Multistage Submersible Pump , Industrial Centrifugal Pumps

Machine of Horizontal Multistage Centrifugal Pump Used In Plants

Feature :

1. High efficiency and wide application range.

2. Pump is stable in run, little noise.

3. The spindle seal has soft stuff seal or hard mechanical seal, safe and reliable, in a simple structure, easy to maintain.

4. Full seal structure, no contact with media, no corrosion, with a long life.

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, diffuse or sleeve and packing. The packing should be proper and leak drop by drop. Forbid unload running. Change seal ring and diffuse or 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.
