Abstract
The utility model provides a front connection structure of a sand suction pump. The front connection structure comprises a front connection structure body and a sand inlet. The edge of the front connection structure body is provided with a plurality of volute connection screw holes in symmetrical distribution, a plurality of sand inlet pipe connection bolts which are symmetrically distributed and integrally formed with the front connection structure body are arranged on the outer periphery of the sand inlet and on the outer side of the front connection structure body, and the front connection structure body is made of white iron. Since the front connection structure of the sand suction pump is made of white iron, and the plurality of sand inlet pipe connection bolts which are integrally formed with the front connection structure body are arranged on the outer periphery of the sand inlet, abrasion resistance of the front connection structure of the sand suction pump is improved, service life of the front connection structure of the sand suction pump is prolonged, direct connection between a pump body and a sand inlet pipe is realized, a protection plate and a protection jacket which need to be fittingly used with the front connection structure in the prior art are omitted, overall structural of the sand suction pump is simplified, and installation and maintenance are facilitated.
Description
Technical field
The utility model relates to a kind of pump, especially relates to a kind of pump cover of Sand pump.
Background technique
Sand pump is made up of spiral case, impeller, backplate, pump cover, bracket and bearing unit etc., and wherein the pump cover of sand inlet one side is called front connecting structure.Front connecting structure of the prior art is all to adopt graphitic pig iron to make, although be easy to processing, not wear-resisting, must be used in conjunction with backplate and sheath, the impact of mortar be could resist preferably, and then existing sand suction pump complex structure, installation and maintenance inconvenience made.
Model utility content
Technical problem: the deficiency existing for prior art, provides a kind of wear-resistant, connecting structure before Sand pump simple in structure, easy for installation.
Technological scheme: connecting structure before the Sand pump that the utility model provides, comprise front connecting structure main body, sand inlet, be provided with multiple symmetrical spiral case connecting screw holes at the edge of front connecting structure main body, its innovation is, described front connecting structure main body adopts white iron to make, in the outside of front connecting structure main body, the periphery of sand inlet, be provided with multiple sand-feeding tube connecting bolts symmetrical and that front connecting structure main body is integrally formed.Described spiral case connecting screw hole is for connecting the spiral case of water pump, the sand-feeding tube that sand-feeding tube connecting bolt forms for connecting liner rubber flanged pipe.
Described spiral case connecting screw hole preferably arranges 12, and sand-feeding tube connecting bolt preferably arranges 8.
Beneficial effect: because connecting structure main body before Sand pump of the present utility model adopts white iron manufacture, and be provided with in the periphery of described sand inlet the sand-feeding tube connecting bolt that multiple and front connecting structure main body is integrally formed, improving the wear resistance of connecting structure before Sand pump and in working life, having realized again the pump housing is connected with the direct of sand-feeding tube, saved in prior art must with the matching used backplate of front connecting structure and sheath, the general structure of having simplified Sand pump, is easy for installation and maintenance.
Accompanying drawing explanation
Fig. 1: connecting structure embodiment's stereogram before Sand pump.
In figure, have: front connecting structure main body 1, sand inlet 2, spiral case connecting screw hole 3, sand-feeding tube connecting bolt 4.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is further described.
Embodiment:
Referring to Fig. 1, connecting structure before the Sand pump of the present embodiment, comprise front connecting structure main body 1, sand inlet 2, be provided with 12 symmetrical spiral case connecting screw holes 3 at the edge of front connecting structure main body, especially, described front connecting structure main body 1 adopts white iron to make, in the outside of front connecting structure main body 1, the periphery of sand inlet 2 is provided with 8 sand-feeding tube connecting bolts 4 symmetrical and that front connecting structure main body 1 is integrally formed.When installation, the front end of the liner rubber flanged pipe of sand-feeding tube is inserted after sand inlet, the flange of liner rubber flanged pipe is connected with connecting structure before Sand pump with sand-feeding tube connecting bolt 4.
The protection domain of the utility model patent is not limited to the concrete scheme of the present embodiment, everyly utilizes the overall technological scheme that the utility model provides and connecting structure before the Sand pump of producing, manufacture, using, and all falls into the protection domain of this patent.
