There is adhesion in axle, and trouble point axle sleeve dismantles operation by the extremely difficult of change, and the method generally used is slowly knocked out with flat chisel, or
Person carries out overall structure destruction with gas welding or other cutting modes to axle sleeve, due to axle sleeve very thin thickness itself, is dismantling
Badly damaged inevitably will be caused to pump shaft and axle sleeve in journey, and whole dismounting operating efficiency is relatively low, secondly as refining
Factory, carries out fire operation in process units region, and safety in production will be hidden some dangers for.
Utility model content
The purpose of this utility model overcomes centrifugal pump axle sleeve removal efficiency low and often results in pump shaft and boss failure
Deficiency is there is provided a kind of with pulling force is big, working range is wide, operating efficiency is high, need not get angry, will not destroy the axle of axle sleeve and pump shaft
Cover extracting tool.
Therefore, the utility model provides a kind of centrifugal pump shaft sleeve withdrawal tool, including snap ring, the anchor ring of described snap ring
The upper circumferentially distributed jackscrew for having multiple insertion snap ring anchor rings；Multiple pull bars are circumferentially uniformly fixed with the outer wall of snap ring；It is many
Individual pull bar is parallel to each other, and one end is welded on snap ring outer wall, and the other end passes through same supporting plate；Tie rod end is socketed with regulation
Nut, adjusting nut is sitting in the outer plate surface of supporting plate；One jack is installed on the inner plate surface of supporting plate.
Circumferentially uniform welding has multiple nuts on the anchor ring of described snap ring, and jackscrew sequentially passes through the ring of nut and snap ring
Face is extend into inside snap ring.
Described jackscrew has three, is uniformly distributed on the anchor ring of snap ring in 120 ° of angles.
Described pull bar has two or three, is uniformly connected on the outer wall of snap ring.
Described jack is installed on the inner plate surface of supporting plate in the way of replaceable is installed.
The beneficial effect for this centrifugal pump shaft sleeve withdrawal tool that the utility model is provided：
1st, pull bar can be adjusted distance by the adjusting nut of supporting plate, go for the pump shaft axle of different length
Set dismounting operation.
2nd, by adjusting the position of jackscrew, various sizes of axle sleeve dismounting operation is gone for.
3rd, according to the dead degree of the embroidery of axle sleeve, the jack of different tonnages is selected to make as power source using hydraulic jack
For power source, the dismounting operation of different dismounting difficulty can be met.
4th, by the dismounting operation of this instrument, the axle sleeve disassembled is carried out after repairing again, still may be used,
Maintenance cost is saved.

Embodiment
Embodiment 1：
The present embodiment provides a kind of centrifugal pump shaft sleeve withdrawal tool, with reference to shown in Fig. 1 and Fig. 2, including snap ring 1, described
The circumferentially distributed jackscrew 6 for having multiple anchor rings of insertion snap ring 1 on the anchor ring of snap ring 1；It is circumferentially uniform fixed on the outer wall of snap ring 1
There are multiple pull bars 2；Multiple pull bars 2 are parallel to each other, and one end is welded on the outer wall of snap ring 1, and the other end passes through same supporting plate 3；
The end of pull bar 2 is socketed with adjusting nut 4, and adjusting nut 4 is sitting in the outer plate surface of supporting plate 3；Installed on the inner plate surface of supporting plate 3
There is a jack 5.
The implementation process of this centrifugal pump shaft sleeve withdrawal tool of the present embodiment is as follows：Dead axle is embroidered as shown in figure 1, running into
When set 8 dismantles operation, snap ring 1 is inserted in axle sleeve 8, jackscrew 6 is adjusted, the active force on the surface of axle sleeve 8 is given by jackscrew 6, is made whole
Jack 5, is put between supporting plate 3 and the shaft end of pump shaft 9, adjustment is adjusted by individual instrument and the one stress entirety of formation of axle sleeve 8 afterwards
The distance of nut 4 is saved, jack 5 and the shaft end of pump shaft 9 is contacted, jack 5 is operated afterwards, under the drive of jack 5, by axle
Set 8 is extracted.By the dismounting operation of this instrument, the axle sleeve disassembled is carried out after repairing again, still may be used, and is saved
About maintenance cost.
Embodiment 2：
The present embodiment is further illustrated on the basis of embodiment 1, as shown in Fig. 2 on the anchor ring of snap ring 1 circumferentially
Uniform welding has multiple nuts 7, and jackscrew 6 sequentially passes through nut 7 and the anchor ring of snap ring 1 is extend into inside snap ring 1.Jackscrew 6 has three
