Abstract
The utility model relates to the technical field of pumps of machinery engineering, in particular to a pump body and pump cover connecting structure, which comprises a pump body and a pump cover. The pump body and pump cover connecting structure is characterized in that the pump body and pump cover connecting structure is provided with connecting screw studs, positioning screw nuts and a fastening screw nut, at least three connecting lug plates are uniformly distributed in the center of the outer periphery of the pump body, a connecting through hole is formed in each connecting lug plate, at least three widened connecting plates are uniformly distributed and arranged on the outer periphery of the pump cover, and the widened connecting plates are fixedly connected with the pump cover through reinforcing ribs, so the integral rigidity of the pump cover can be favorably improved, connecting threaded holes are formed in the outer ends of the widened connecting plates, the connecting screw studs pass through the connecting threaded holes and realize the positioning connection with the pump cover through screw threads via the positioning screw nuts, and then, the other ends of the connecting screw studs pass through the connecting through holes to be fixedly connected with the pump body through the positioning screw nuts. The pump body and pump cover connecting structure has the advantages that the structure is reasonable, the operation is convenient and fast, the dismounting is convenient, the sealing performance is high, and the like.
Description
Technical field
The utility model relates to mechanical engineering pump technical field, specifically a kind of pump housing pump cover linkage structure of convenient disassembly.
Background technique
Centrifugal pump extensive use industry-by-industry, comprises metallurgy, mine, petrochemical industry, municipal administration etc. at present.Pump may produce fault in operation process.Field maintenance requires the dismounting of pump must be fast, convenient, and the time that makes to delay production is the least possible.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of rational in infrastructure, simple operation, convenient disassembly, pump housing pump cover linkage structure that sealability is high are provided.
The utility model solves the technological scheme that its technical problem adopts:
A kind of pump housing pump cover linkage structure, comprise the pump housing and pump cover, it is characterized in that being provided with connecting stud, setscrew nut and tightening nut, described pump housing periphery center is laid with at least three and connects otic placode, connect otic placode and be provided with connecting through hole, described pump cover periphery is laid with at least three and widens connecting plate, widening connecting plate is fixedly connected with pump cover through strengthening muscle, be beneficial to improve the integral rigidity of pump cover, widen connecting plate outer end and be provided with connecting thread hole, after connecting stud is located by connecting through connecting thread aperture setscrew nut and pump cover screw thread, the other end is fixedly connected with the pump housing through setscrew nut through connecting through hole, by increasing the distance of connecting stud and pump housing center line, increase the sealed force moment of pump housing pump cover, and, the sealed force moment that connecting stud by the uniform connection of pump housing periphery produces, guaranteed that the pump housing all can produce sealing load on whole circumferencial direction, the sealing that guarantees whole circumferencial direction is reliable.And during dismounting, only need by connecting stud near the setscrew nut dismounting of the pump housing, convenient, simple, practical.
The present invention is owing to adopting said structure, has rational in infrastructure, simple operation, convenient disassembly, sealability advantages of higher.

Reference character: the pump housing 1, pump cover 2, connecting stud 3, setscrew nut 4, tightening nut 5, connect otic placode 6, widen connecting plate 7, strengthen muscle 8.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of pump housing pump cover linkage structure, comprise the pump housing 1 and pump cover 2, it is characterized in that being provided with connecting stud 3, setscrew nut 4 and tightening nut 5, the described pump housing 1 periphery center is laid with at least three and connects otic placode 6, connect otic placode 6 and be provided with connecting through hole, described pump cover 2 peripheries are laid with at least three and widen connecting plate 7, widening connecting plate 7 is fixedly connected with pump cover 2 through strengthening muscle 8, be beneficial to improve the integral rigidity of pump cover 2, widen connecting plate 7 outer ends and be provided with connecting thread hole, after connecting stud 3 is located by connecting through connecting thread aperture setscrew nut 4 and pump cover 2 screw threads, the other end is fixedly connected with the pump housing 1 through setscrew nut 4 through connecting through hole, by increasing connecting stud 3 and the distance of the pump housing 1 center line, increase the sealed force moment of the pump housing 1 pump cover 2, and, the sealed force moment that connecting stud 3 by the uniform connection of the pump housing 1 periphery produces, guaranteed that the pump housing 1 all can produce sealing load on whole circumferencial direction, the sealing that guarantees whole circumferencial direction is reliable.And during dismounting, only need by connecting stud 3 near setscrew nut 4 dismounting of the pump housing 1, convenient, simple, practical.
The present invention is owing to adopting said structure, has rational in infrastructure, simple operation, convenient disassembly, sealability advantages of higher.
