The purpose of this utility model can be realized by following technical proposal：A kind of new cut-up type blow-down pump, including pump
Body and the bottom base being fixedly connected with by bolt and the pump housing, described bottom base have hollow vane room, and and vane room
Interconnected inlet and liquid outlet, the described pump housing is interior to set the motor for being provided with kinetic energy, it is characterised in that the electricity
The arbor of motivation is extend into the vane room of bottom base through pump housing lower surface, be disposed with described vane room impeller,
Auxiliary blade group and cut-off blade are connected with arbor, are provided with the inner face of described inlet and match with cutting impeller
The gear ring of conjunction, described auxiliary impeller sets include annular blade and the annular blade pedestal being connected with vane room, described ring
Shape blade base has the limited hole loaded at circular body and main center for annular blade, described annular blade base
Seat top surface is provided with multiple segmentation blades.
Originally the technique effect of new cut-up type blow-down pump is：During motor start-up, motor arbor driving impeller, auxiliary lobe
Piece group and cut-off blade rotate simultaneously sucks inlet by sewage, and the cut-off blade and gear ring in blade wheel chamber carry out the to impurity thing
Pulverization process, then the segmentation blade on annular blade and annular blade pedestal perform second of pulverization process, to improve
Dust efficiency is to precipitation without condensation, it is ensured that impurity is fluffy and reduces what is condensed and be stuck before impurity thing is discharged to impeller
Possibility, then by the rotation driving sewage of impeller, then discharged by liquid outlet, so as to expeditiously eliminate impurity.
In a kind of above-mentioned new cut-up type blow-down pump, there is equally distributed shunting on described gear ring internal perisporium
Hole.Prevent from sucking big impurity, cause the blocking of inlet.
In a kind of above-mentioned new cut-up type blow-down pump, the upper surface of the gear ring and the body level of cut-off blade are right
Together.So that cut-off blade is integrally just entrapped in gear ring, prevent cut-off blade from radial-play occurs, produce noise.
In a kind of above-mentioned new cut-up type blow-down pump, described annular blade susceptor edges part offers several
Mounting hole, described annular blade pedestal are connected by the lower surface of mounting hole and blade wheel chamber.Prevent annular blade pedestal in water
Generation is rocked under the impact of stream, influences the job stability of dredge pump.
In a kind of above-mentioned new cut-up type blow-down pump, each described segmentation blade has inclined plane, and described inclines
Inclined-plane has the sharp inward flange towards and around through hole.
Compared with prior art, this new cut-up type blow-down pump is provided with two distinct types of blade to miscellaneous in sewage
Matter is filtered, crushed, and accelerates the discharge to impurity while preventing impurity to blowdown pump block, is had stable performance, is removed
The advantages of dirty efficiency high.
