Machine of Horizontal Multistage Centrifugal Pump Used In Plants
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
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#
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
