Abstract
The utility model relates to a novel horizontal multi-stage pump stamping tooling, which comprises a water inlet section, a middle section, a water outlet section and a pull rod, wherein the pull rod is sequentially connected with the water inlet section, the middle section and the water outlet section. The novel horizontal multi-stage pump stamping tooling is characterized in that the novel horizontal multi-stage pump stamping tooling also comprises two press covers and a cover plate, wherein the press covers, the water inlet section, the cover plate, the middle section, the water outlet section and the press cover are sequentially connected through the pull rod, and screw nuts for fixing the whole stamping tooling are screwed at both ends of the pull rod. The novel horizontal multi-stage pump stamping tooling disclosed by the utility model has the advantages of simple structure, low cost and high whole-machine production efficiency, so the possibility of generating whole-machine unqualified water pressure is effectively reduced.
Description
Technical field
The utility model relates to a kind of novel horizontal type multi-stage pump and suppresses frock.
Background technique
Existing suppressing of horizontal multi-stage centrifugal pump all is good inlet segment, stage casing and the assembly unit of water exit end complete machine, carries out the whole hydrostatic test again, because this mode part of suppressing must assembly unit back aptitude tests well.But run into underproof part is arranged in the hydrostatic test, then mostly need to remove complete machine, and the structure of complete machine is quite complicated, and underproof part is taken out, not only difficulty but also when taking a lot of work, this method must be to the complete machine certain influence of efficient generation of dispatching from the factory.In view of the foregoing, demand developing the structure that a kind of novel horizontal type multi-stage pump is suppressed frock urgently, to satisfy the demand that people improve constantly.
Summary of the invention
The purpose of this utility model has provided a kind of novel horizontal type multi-stage pump and has suppressed frock, has solved the deficiencies in the prior art.
The purpose of this utility model is achieved in that a kind of novel horizontal type multi-stage pump suppresses frock, comprise: inlet segment, stage casing, water exit end, pull bar, wherein, pull bar be linked in sequence inlet segment, stage casing and water exit end, it is characterized in that: also comprise two glands and cover plate, described gland, inlet segment, cover plate, stage casing, water exit end, gland are linked in sequence by pull bar, are rotary with the fixing whole nut of suppressing frock at the two ends of pull bar.
The utility model has the advantages that: simple in structure, with low cost, complete machine manufacturing efficiency height, thus effectively reduced the possibility that the defective hydraulic pressure of complete machine takes place.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic representation.
Accompanying drawing 2 be the utility model structural representation.
Below in conjunction with drawings and Examples the utility model is elaborated.
Embodiment
Among the figure, a kind of novel horizontal type multi-stage pump is suppressed frock, comprise: inlet segment 2, stage casing 4, water exit end 5, pull bar 6, wherein, pull bar 6 be linked in sequence inlet segment 2, stage casing 4 and water exit end 5, it is characterized in that: also comprise two glands 1 and cover plate 3, described gland 1, inlet segment 2, cover plate 3, stage casing 4, water exit end 5, gland 1 are linked in sequence by pull bar 6, are rotary with the fixing whole nut 7 of suppressing frock at the two ends of pull bar 6.
The staff processes the cover plate 3 that a two sides cooperates with inlet segment 2 and stage casing 4 respectively earlier, then, described gland 1, inlet segment 2, cover plate 3, stage casing 4, water exit end 5, gland 1 are linked in sequence by pull bar 6, with gland 1 sealing, fix with plain nut 7 then.
During use, the staff is respectively to water exit end 5, and stage casing 4 and inlet segment 2 carry out the hydrostatic test, the complete machine hydrostatic test after qualified again these parts the assemblings afterwards, thus effectively reduced the possibility that the defective hydraulic pressure of complete machine takes place.
Below only expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
The utility model advantage is: simple in structure, with low cost, and complete machine manufacturing efficiency height, thus effectively reduced the possibility that the defective hydraulic pressure of complete machine takes place.
