Description
Technical field
Pump class shafting dismounting positioning special tool is the utility model is related to, is torn open more particularly, to one kind for nuclear power station water pump
The shafting positioner of dress.
Background technology
Nuclear power station has water pump under many vertical long liquid, and this pump is typically made up of more axles, passes through shaft coupling between axle and axle
Pipe nipple connects, and guide bearing is provided with jackshaft, impeller is fixed on minor details axle by sleeve.Shafting positioning at present uses
Method be lean against to carry out measurement and positioning on intake flange face by guiding ruler, or line makes marks on impeller sleeve
Problems be present in method, both approaches:
1) the low relative position for influenceing impeller on axle of installation site installation measurement accuracy of shaftings, the output of pump is influenceed；
2) influences the cooperation of chromium coating position and guide bearing position on axle, repair quality it is difficult to ensure that.
Utility model content
The purpose of this utility model is exactly to be used for nuclear power to provide one kind the defects of overcoming above-mentioned prior art to exist
The shafting positioner of water pump of standing dismounting.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of shafting positioner for the dismounting of nuclear power station water pump, the shafting positioner is discoid, disc structure
Clamp screw keyhole and spindle nose screwed hole are provided with, described clamp screw keyhole is trough type clamp screw keyhole, around disc centre
Radially it is uniformly distributed.
Described spindle nose screwed hole is located at disc centre.
Described shafting positioner includes at least four clamp screw keyhole.
Described spindle nose screwed hole is surrounded by round table-like projection.
Described round table-like projection thickness is 10mm.
The described a width of 21mm of trough type clamp screw keyhole, a length of 91mm, spindle nose screwed hole is the circle that radius is 36mm
Hole.
Described clamp screw keyhole and spindle nose screwed hole is through hole.
Compared with prior art, the utility model has advantages below：
1), stability is good, measurement accuracy is high：This instrument accurately, can be contacted reliably with equipment, ensure that the accurate of measurement
Property；
2) it is, easy to operate：This specific purpose tool is simple in construction, small volume, in light weight, can quickly install and use；
3) it is, applied widely：Due to the setting of trough type clamp screw keyhole so that device goes for sizes
Water pump.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that described embodiment is part of the embodiment of the present utility model, rather than is all implemented
Example.Based on the embodiment in the utility model, those of ordinary skill in the art institute on the premise of creative work is not made
The every other embodiment obtained, it should all belong to the scope of the utility model protection.
Embodiment
A kind of shafting positioner for the dismounting of nuclear power station water pump, the shafting positioner is discoid, disc structure
Clamp screw keyhole 2 and spindle nose screwed hole 1 are provided with, spindle nose screwed hole 1 is located at disc centre, and clamp screw keyhole 2 is trough type, is enclosed
Radially it is uniformly distributed around disc centre, as shown in Figure 1.
Shafting positioner includes at least four clamp screw keyhole 2.Clamp screw keyhole and spindle nose screwed hole are through hole.
Spindle nose screwed hole is surrounded by round table-like projection 3, as shown in Figure 2.
Round table-like projection thickness is 10mm, and round table-like projection outer radius is 46mm.The a width of 21mm of trough type clamp screw keyhole,
A length of 91mm, spindle nose screw thread pore radius are 36mm.Disk integral radius is 165mm.
Application method is：
1) shafting positioner 4, is arranged on Pump Suction Nozzle, and fixed (as shown in Figure 3) with four fastening bolts 5；
2), impeller axle (piece axle in shafting bottom) is altered into from suction inlet side, and is screwed into shafting positioner 4
In screwed hole (as shown in Figure 3)；
3), measure the end face of shafting positioner 4 and arrive the distance between spindle nose, it is kept one with the measurement data before disintegration
Cause；
4) suction inlet 6 and blower inlet casing 7, are connected, impeller 8 is put into blower inlet casing 7, fixed with sleeve, method is pacified like this
Other impellers are filled, so far position positioning of the impeller on axle is completed；
5) shafting positioner 4, is dismantled.
Used in nuclear power station drum net flush water pump is water pump under typical vertical long liquid.Drum net flush water pump is being installed or disintegrated
During the whole shafting position among equipment be to be accurately positioned, after causing equipment to be disintegrated, not may be referred to
Data come instruct back fill work.Shafting can accurately and reliably be positioned using this shafting positioner, and then ensure leaf
