Description
Technical field
The utility model belongs to the technical field of MODEL VERTICAL MULTISTAGE PUMP, refers in particular to a kind of pump barrel structure of MODEL VERTICAL MULTISTAGE PUMP.
Background technique
MODEL VERTICAL MULTISTAGE PUMP is a kind of centrifugal pump with multiple impellers, and the equipment as water supply and drainage is widely used in various rows
Industry.The inner cylinder outer tube structure of the existing MODEL VERTICAL MULTISTAGE PUMP in market is mostly integral cast steel structure, disadvantage is that: technique is multiple
Miscellaneous, higher cost, environmental pollution is larger when castings production.
To overcome the above disadvantages, some enterprises are applied to punch welding technology in MODEL VERTICAL MULTISTAGE PUMP, but compared to casting
The MODEL VERTICAL MULTISTAGE PUMP of part production, MODEL VERTICAL MULTISTAGE PUMP structural strength made of punch welding is not high, and service life is also long without casting.
Utility model content
The purpose of the utility model is to provide a kind of pump barrel structure of MODEL VERTICAL MULTISTAGE PUMP, simple process and low cost, environment
Close friend, and have performance identical with integral cast steel part.
Purpose of the utility model is realized as follows: a kind of pump barrel structure of MODEL VERTICAL MULTISTAGE PUMP, including inner cylinder, outer cylinder,
Water supply connector and water outlet connector, the water supply connector are connected with inner cylinder, the cavity between the water outlet connector and inner barrel and outer barrel
It is connected, when work, forms low-pressure chamber inside inner cylinder, the cavity between inner cylinder and outer cylinder forms hyperbaric chamber, the inner barrel and outer barrel
Punching stretch forming respectively, the upper end of inner cylinder is arranged at intervals with flange, the bulge loop of convex is provided on the inner wall of outer cylinder, described to turn over
While being welded on bulge loop.
The bottom of above-mentioned outer cylinder is provided with interior concave plane, the bottom contact connectio of interior concave plane and inner cylinder.Preferably, above-mentioned
Interior concave plane is circle, and radius is less than inner cylinder.
Above-mentioned water supply connector and water outlet connector are located at same axis.
Above-mentioned water supply connector, water outlet connector include joint body and flange, and the joint body and flange are integrally formed.
Connection screw thread is provided in above-mentioned water supply connector and water outlet connector.
Annular groove is provided in the outer circumferential walls of above-mentioned flange.
Compared with the prior art, the utility model has prominent and beneficial technical effects that:
1, the pump barrel structure of MODEL VERTICAL MULTISTAGE PUMP provided by the utility model, by stretching welding fabrication, compared to current city
Integral cast steel structure on field, cost is lower, to less pollution caused by environment in production process, meanwhile, this is practical
The novel pump barrel structure by unique design has and whole so that pump barrel, which overcomes, stretches the lower problem of welding structure intensity
The performance that body formula cast steel structure compares favourably.
2, the joint body of the utility model and flange are an integral structure, more firm compared to traditional separate structure
Gu it is more easier to install, meanwhile, the connector of the utility model can be with a variety of connection types such as standard flange and/or threaded connections.
