Disassembling illustrations, stainless steel pump impeller pump stainless steel impeller removal methods

For stainless steel, stainless steel pump shell can transport corrosive medium, according to different medium corrosive to choose the appropriate stainless steel material, its impeller using the standard 304 material, after the blank casting, rough machining, finish machining and a series of process of casting. Stainless steel impeller encountered a lot of wear and tear or corrosion damage phenomenon, you need to remove the water pump impeller, remove the stainless steel pump impeller method and remove the order of the stainless steel impeller pump is as follows:

1, remove the pump impeller need to measure the rotor axial momentum and radial runout, the measuring rotor axial momentum and radial beat is normal and record as shown in figure 1 A week 11, the rotor rotation, the maximum reduction of the minimum of the same measuring point is the point of beating

2, and then remove the impeller back cap, remove the impeller, remove the former confirm back cap handedness, forbidding reverse forcibly damage back cap, as shown in figure 1 12, the impeller with a crowbar to pry, to pry in the floor of the impeller, lest will pry impeller crack, as shown in figure 1 13, appearance inspection impeller back cap shall be deducted without a bite and the phenomena of silk, or should be repaired or replaced.

stainless steel water pump impeller removal methods of figure

stainless steel pump impeller removal methods:

remove the impeller with special spanner toward the twist in the same direction and the impeller rotating impeller under the nut, remove the check back washers, impeller can be removed. If not come down, available pipe sleeve shaft head with slight tapping with a hammer casing head, loose impeller after can remove, such as rust on the shaft, impeller with kerosene after baptism. Tools:

remove need special wrench, casing, hammer

remove the stainless steel impeller note:

1) Be prepared to put parts of workbench, also can be put on the board, throw, the place of avoid by all means.

        （ 2) To the rational use of special tools.

        （ 3) Removing the parts cooperate closely, to cushion good wood with a hammer, ban with a hammer pounding the components.

        （ 4) Must be kept in combination with smooth surface, the friction surface and machining surface clean, must not touch the injury and damage.

stainless steel impeller pump disassembly sequence:

1, twist the spit out side bearing gland bolts and spit on the section, packing box, bearing coupling nut off bearing between the three components:

2, round nut on the screw shaft under, in order to unload bearing inner ring, bearing gland and block set, remove packing ( Including the packing gland, packing ring and packing, etc. ) :

3, in turn off the shaft type O sealing ring, shaft sleeve, balance disc and keys, unload spit ( Including level at the end of the guide vane and the gimbal ring, etc. ) ;

4, level off at the end of the impeller and keys, landed in the middle, Including the guide vane) : on the same terms and methods continue to remove the remaining leaf wheel, middle and guide vane, at all levels until discharged head impeller:

5, unscrewed the connecting the suction section with the bearing body on bolt, nut and bearing pressure unloading bearing parts;

6, take out shaft from the suction section, fixed nut on the screw shaft under, in turn bearing inner ring, type O sealing ring, shaft sleeve, and set off.
