Description
Technical field
The utility model belongs to detaching equipment field, and in particular to a kind of centrifugal pump closed type impeller standby cap provision for disengagement.
Background technique
Method used in original disassembly centrifugal pump impeller standby cap is heating, i.e., sets about from contact surface, since impeller is standby
Cap section is fitted closely with impeller face, and is run under water for a long time, and the big substance of more hardness has been gathered at contact surface, these
Substance is hard and is difficult to, and impeller standby cap is difficult to back out, and need to use gas welding Baking out impeller standby cap position, makees in high temperature
With the lower substance for generating and being easy to remove.Standby cap can expand at high temperature simultaneously, and being subject to be vibrated with hand hammer loosens contact surface, then uses
Spanner could smoothly back out standby cap.
When each impeller maintenance disassembly standby cap, all need to heat impeller standby cap position using heating, the method is not
There is only the risks for causing standby cap and impeller failure, it is easier to the physicochemical properties of spindle nose position distortions, axis be caused to occur
Variation even can lead to bending shaft and scrap, and need multiplexing kind to match when stablizing safe operation for equipment and bring huge hidden danger, while overhauling
It closes and consumes a large amount of manpower and material resources.
When using tool ejector standby cap, spanner is separated from standby cap immediately after reinforcing, cannot smoothly be backed out standby cap,
So technical problems to be solved have two aspects: first is that need to solve to design a kind of can also dismantle standby cap without the use of heating
Method；Second is that spanner is easily detached from standby cap when need to solve the problem of to dismantle standby cap using spanner.
Utility model content
The utility model by using force analysis method, when analysis is using tool ejector standby cap, the spanner after reinforcing
Immediately with the out of gear mesh true cause of standby cap.Dismantling tool by applying the method for external force according to the equilibrium principle of power later
Spanner and impeller standby cap do not depart from out when impeller standby cap, smoothly back out the standby cap of impeller.Specific technical solution is as follows:
A kind of centrifugal pump closed type impeller standby cap provision for disengagement, including socket head, extension rod, flat cover shape disk, reinforcing
Bar, the socket head are fixedly connected with extension rod, the flat cover shape middle of the disc through-hole and insertion box spanner
Extension rod matches, and slides on extension rod, rotation；Flat cover shape disk protrusion side is goed deep into inside impeller port ring, and and its
Cooperation；Flat cover shape disk outer radius portion stays in impeller port ring outer end, and is bonded with impeller port ring outer end face；Extension bar is through extension
In bar remote stomidium.
The beneficial effects of the utility model
Centrifugal pump closed type impeller standby cap provision for disengagement can smoothly disassemble impeller standby cap, compared to traditional heating side
Method has the following advantages:
1. the invention is physical removal method, is heated without the use of gas welding, can effectively avoid spindle nose part heated bending, because
This will not damage pump shaft.
2. the mechanical fittings such as pair impeller of pump, impeller standby cap, lock pad do not injure, do not influence to reuse.
3. only two people, same work post can construct, the cooperation of the work posts such as gas welding is not needed, manpower and material resources consumption is few, time saving
It is laborsaving, save a large amount of maintenance funds.
4. method for dismounting is simple, the repair time is greatly shortened, stronger guarantee equipment safety, production is steadily.
Detailed description of the invention
Fig. 1 is the utility model centrifugal pump closed type impeller standby cap provision for disengagement schematic diagram；
1- socket head, 2- extension rod, 3- flat cover shape disk, 4- extension bar
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Embodiment 1
A kind of centrifugal pump closed type impeller standby cap provision for disengagement, including 71mm national standard driving end extend as socket head 1
Bar 2 isIt carbon steel pipe (length 280mm) one, is bored at 245mmHole.Driving end 1 is soldered toThe pipe drilling other side, flat cover shape disk 3, extension bar 4,3 intermediate throughholes of flat cover shape disk and insertion sleeve
The extension rod 2 of spanner 1 matches, and slides on extension rod 2, rotation；The raised side of flat cover shape disk 3 is goed deep into impeller port ring
Portion, and cooperate with it；3 outer radius portion of flat cover shape disk stays in impeller port ring outer end, and is bonded with impeller port ring outer end face；Reinforcing
Bar 4 is through in 2 remote stomidium of extension rod.
