Description
Technical field
The utility model belongs to the technical field of submersible pump, is related to a kind of anti-submersible pump to spin.
Background technique
Submersible pump refers to pump housing impeller and the motor of impeller is driven all to pull the plug a kind of water pump of work, existing latent
Water power pump is since there are gaps between top chock and top cover, and top chock has the phenomenon that spinning when in use.
It spins in order to prevent and rubber washer is usually installed between top chock and the gap of top cover, top cover passes through compression rubber
Rubber gasket compresses top chock, spins to prevent top chock.Under normal conditions after electric pump operation a period of time, rubber pad
Aging is enclosed, elastic force failure, top chock can still have risk of spinning, and then influence bearing life, to influence the electric pump service life.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of anti-submersible pumps to spin, and structure is simple, at
This is cheap, can thoroughly solve the problems, such as that the top chock of submersible pump spins.
In order to solve the above technical problems, the purpose of this utility model is achieved by following technical proposals:
A kind of anti-submersible pump to spin, including base, top cover and top chock, the top chock are fitted in base
On, the top cover is assemblied in the top of base and top chock, and passes through the rubber washer between compression top cover and top chock
It is fixed top chock, the upper surface of the top chock is provided with top chock boss, is provided on top chock boss
Perforative U-type groove, the top cover inner wall are provided with the top cover gusset matched with U-type groove, and the limit of top cover gusset is U-shaped after assembly
In slot.
The edge of top chock is arranged in above-mentioned top chock boss, and top cover inner wall side is arranged in the top cover gusset
Corresponding position.
Clearance fit between above-mentioned top cover gusset and U-type groove.
O-ring seal is provided between above-mentioned top cover and base.
The lower section week of above-mentioned top cover is equipped with bolt hole, and is fastenedly connected by bolt and base, and then compressing rubber washer
To compress top chock.
Compared to the prior art the utility model, has the following beneficial effects:
1, the utility model is matched by top cover gusset with the boss with U-type groove on top chock, is thoroughly solved
The problem of top chock of submersible pump spins.After assembly, top cover gusset is limited in U-type groove, since top cover is tight with base
It being solidly connected, top cover gusset is also just fixed, and top cover gusset limits the movement of boss, it carries out limiting the rotation of top chock,
Even if rubber washer aging in use, elastic force failure, top chock as the limitation of top cover gusset and be kept fixed not
It is dynamic.
2, allow that there are gaps between the top cover gusset and U-type groove of the utility model, therefore the processing required in processing
Precision is low, when will not additionally increase excessive cost, and assemble also more easily, will not additionally improve assembly difficulty.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model；
Fig. 2 is the perspective view of the utility model top cover；
Fig. 3 is the perspective view of the utility model top chock；
In figure: 1, base；2, top cover；3, top chock；4, rubber washer；5, top chock boss；6, U-type groove；7, it pushes up
Lid gusset；8, O-ring seal；9, bolt hole；10, bolt.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1-3:
A kind of anti-submersible pump to spin, including base 1, top cover 2 and top chock 3, the top chock 3 are fitted in machine
On seat 1, the top cover 2 is assemblied in the top of base 1 and top chock 3, and by between compression top cover 2 and top chock 3
Rubber washer 4 is fixed top chock 3, and the upper surface of the top chock 3 is provided with top chock boss 5, top chock
Perforative U-type groove 6 is provided on boss 5,2 inner wall of top cover is provided with the top cover gusset 7 matched with U-type groove 6, after assembly
Top cover gusset 7 limits in U-type groove 6.
Preferably, the edge of top chock 3 is arranged in above-mentioned top chock boss 5, and the top cover gusset 7 is arranged in top cover
The corresponding position of 2 inner wall sides.
In order to reduce processing cost and assembly difficulty, clearance fit between above-mentioned top cover gusset 7 and U-type groove 6.
O-ring seal 8 is provided between above-mentioned top cover 2 and base 1.
It is equipped with bolt hole 9 the lower section week of above-mentioned top cover 2, and is fastenedly connected by bolt 10 with base 1, and then compressing rubber
Washer 4 compresses top chock 3.
The assembly method of the utility model is as follows: first top chock 3 being fitted on base 1, then on top chock 3
It is arranged rubber washer 4, O-ring seal 8 is arranged on top cover 2, the alignment of top cover gusset 7 U-type groove 6 is put into top cover 2, makes top cover 2
Lower convex edge push down rubber washer 4, O-ring seal 8 is located in the annular groove of base 1, is fastenedly connected top by bolt 10 later
Lid 2 and base 1 complete assembly.
After assembly, top cover gusset 7 is limited in U-type groove 6, since top cover 2 and base 1 are fastenedly connected, top cover gusset 7
Just it is fixed, top cover gusset 7 limits the movement of top chock boss 5, it carries out limiting the rotation of top chock 3, even if
4 aging of rubber washer in use, elastic force failure, top chock 3 as the limitation of top cover gusset 7 and remain stationary.
Above-described embodiment is only the preferred embodiment of the utility model, is not limited the scope of the invention according to this, therefore:
The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection scope of the utility model it
It is interior.
