The impeller comprises a front cover, an inlet, an outlet and a water channel, a center hub extending out of the casing extends from the inside of the inlet of the water channel to the direction of the front cover, an annular dummy club is arranged on the external surface of the edge of the center hole of the front cover, a water inlet communicated with the water channel is arranged between the annular dummy club and the center hub, an annular groove is arranged on the internal surface of the center hole of the casing cover and the annular dummy club of the front cover can be floated radially on the annular groove to let the sand grain passing through, a specific clearance is reserved between the external diameter of the impeller and the internal diameter of the impeller casing, the seizure of the impeller caused by the sand grain and small rock during the water suction process can be prevented, and the normal operation of thepump can be ensured.
Description
Technical field
The utility model belongs to the impeller technical field, refers in particular to a kind of anti-jamming impeller assembly.
Background technique
Impeller assembly generally includes the impeller housing that is installed in or is operatively coupled on the central driving shaft, in the enclosure, impeller links to each other with this axle, impeller generally includes cover plate and the vane plate between each cover plate up and down, one side of the impeller housing of the fluid of want pumping is incorporated in this impeller housing, the axle rotation, thus make the impeller assembly rotation, in impeller housing, produce high fluid pressure district and low hydrodynamic pressure district thus and impeller assembly is passed in the fluid pumping.
There are some shortcomings in this impeller assembly: impeller is some grains of sand in the process of suction, the rotation of the stuck impeller of hardware granules such as finger stone meeting, thus suction is interrupted, influence the proper functioning of pump.
Summary of the invention
The purpose of this utility model provide a kind of can be by the anti-jamming impeller assembly of the stuck impellers of hardware granule such as the grains of sand, finger stone.
The purpose of this utility model is achieved in that
Anti-jamming impeller assembly, comprise the impeller housing that is provided with center hole, housing lid and impeller, housing lid covers on impeller housing, in the cavity of impeller between housing lid and impeller housing, the inboard outer of impeller housing bottom surface is provided with circumferentially uniform water outlet, the outer radial of impeller housing bottom surface is provided with spirality water outlet guide plate, impeller includes protecgulum, preceding postoperculum is arranged on radially, there are import and export at two, the circumferential uniform spiral of border seal is the open form flow channel gradually, the center hub of stretching out outside the housing lid is extended in the inboard of the inlet of flow channel to the protecgulum direction, the edge outer surface of protecgulum center hole is provided with annular boss, be provided with the water intake that communicates with flow channel between annular boss and the center hub, the annular boss that the internal surface of housing lid central hole is provided with protecgulum thereon radial floating so that the annular groove that the grains of sand pass through has certain clearance between the outer warp of impeller and the interior warp of impeller housing.
Annular groove place on the above-mentioned housing lid is provided with the metallic packing ring of annular.
The center hole of above-mentioned impeller housing is provided with ceramic-seal ring.
It is being on the outer shroud of circular groove buckle closure at impeller housing of using on the housing lid internal surface outer on the impeller housing that above-mentioned housing lid covers.
The outstanding compared to existing technology advantage of the utility model is: impeller is in the space that radially is reserved with radial floating of impeller housing, axially be reserved with the gap, in the suction running, generally can not guaranteed the proper functioning of pump by the rotation of the stuck impellers of hardware granule such as the grains of sand, finger stone.
Description of drawings
Fig. 1 is a three-dimensional exploded view of the present utility model;
The sectional view of the impeller that Fig. 2 is;
Fig. 3 is a structure principle chart of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3:
Anti-jamming impeller assembly, comprise and be provided with center hole 11,31,21 impeller housing 10, housing lid 30 and impeller 20, housing lid 30 covers on impeller housing 10, in the cavity of impeller 20 between housing lid 30 and impeller housing 10, the inboard outer of impeller housing bottom surface 12 is provided with circumferentially uniform water outlet 15, the outer radial of impeller housing bottom surface 12 is provided with spirality water outlet guide plate 13, impeller 20 includes protecgulum 22, protecgulum 20 rear portions are arranged on radially, there are import and export at two, the circumferential uniform spiral of border seal is the open form flow channel gradually, the center hub 24 of stretching out outside the housing lid 30 is extended in the inboard of the inlet of flow channel to protecgulum 30 directions, the edge outer surface of protecgulum 22 center holes 21 is provided with annular boss 23, be provided with the water intake that communicates with flow channel between annular boss 23 and the center hub 24, the annular boss 23 that the internal surface at housing lid 30 center holes 31 places is provided with protecgulum 22 thereon radial floating so that the annular groove 32 that the grains of sand pass through has certain clearance between the outer warp of impeller 20 and the interior warp of impeller housing 10.
The center hole 11 of above-mentioned impeller housing 10 is provided with ceramic-seal ring 14.
It is being on the outer shroud of circular groove 33 buckle closures at impeller housing of using on the housing lid internal surface outer on the impeller housing 10 that above-mentioned housing lid 30 covers.
Use of the present utility model: the center hub 24 on the impeller 20 is connected with line shaft, and but impeller 20 is rotated, and then with the water intake suction of water from impeller 20, water outlet from impeller 20 outers after centrifugal supercharging throws away, the high pressure water one road that throws away is from the water outlet guide plate 13 output high pressure waters in 12 outsides, impeller housing bottom surface, one the tunnel flow to the back of impeller 20, annular boss 23 on the protecgulum 22 of impeller 20 is pressed on the annular groove 32 on the housing lid 30, because impeller 20 can be done radial pulsation on the annular groove on the housing lid 30 32, as the grains of sand, when finger stone has resistance when the water outlet of impeller 20 throws away, the radial pulsation of impeller 20 can in time make the jammed grains of sand, finger stone passes through smoothly, has reached to prevent the grains of sand, the purpose of the hard stuck impeller assembly of thing such as finger stone.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model according to this; so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
