Abstract
The utility model discloses a centrifugal pump with a cutting device. The centrifugal pump comprises a pump body, a centrifugal pump hub, an impeller and cutting knives, wherein the centrifugal pump hub, the impeller and the cutting knives are mounted in the pump body. The centrifugal pump is characterized in that the centrifugal pump hub is composed of a conical boss; the four cutting knives are symmetrically arranged on the conical boss; the cutting knives are integrally cast with the conical boss. The centrifugal pump with the cutting device has the advantages that the cutting efficiency of the cutting knives is high, and the working efficiency of the pump is high.
Description
Technical field
The utility model relates to a kind of centrifugal pump, is specifically related to a kind of centrifugal pump with cutting device.
Background technique
Centrifugal pump is utilize vane rotary and make the centrifugal force of water generates carry out work; Water pump, before startup, must make to be full of water in pump case and suction sleeve, and then starting electrical machinery makes pump shaft impeller and water do high speed rotary motion, and water, under the effect of centrifugal force, is thrown toward impeller outer edge, flows into the setting-out pipeline of water pump through the runner of volute pump case; Therefore, the size of fluid impact power acting directly has influence on centrifugal pump performance; Existing centrifugal pump wheel hub is circle structure, and fluid is larger to its frontal impact, and centrifugal pump wheel hub is had to certain injury, and simultaneously due to the resistance of centrifugal pump, to have caused also to the acting of fluid impact power certain weak; Existing slitting wheel cutting efficiency is not high simultaneously, and convection cell has certain resistance simultaneously.
Model utility content
For addressing the above problem, the utility model object is in providing a kind of centrifugal pump with cutting device, and the utility model redesigns centrifugal pump wheel hub, also slitting wheel is optimized simultaneously, has reduced the resistance of its convection cell.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of centrifugal pump with cutting device, comprises the pump housing, centrifugal pump wheel hub, impeller (not shown) and slitting wheel composition; Described centrifugal pump wheel hub, impeller and slitting wheel are arranged in the pump housing; Described centrifugal pump wheel hub is made up of cone boss; On described cone boss, be evenly provided with 4 slitting wheel; Described slitting wheel and cone boss integrally casting; The direction of the cutting edge of described slitting wheel is consistent with vane rotary direction.
Further, the edge length of 4 described slitting wheel and height reduce one by one from four slitting wheel of first slitting wheel to the.
Beneficial effect:
Centrifugal pump with cutting device of the present utility model, compared with prior art, has been arranged to cone boss structure by centrifugal pump wheel hub, and convection cell play the guiding role well, reduces the impact to centrifugal pump wheel hub, improves the loss of fluid frontal impact simultaneously; Slitting wheel and cone boss integrally casting, bowlder outside gold machining, cutting edge self-assembling formation; Without special processing, manufacturing efficiency is higher; Adopt the height slitting wheel different with length, in fully cutting, can reduce convection cell acting, reduced air horsepower, improved the efficiency of pump.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model centrifugal pump wheel hub.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
A kind of centrifugal pump with cutting device of the present utility model, comprises that the pump housing 1, centrifugal pump wheel hub, impeller (not shown) and slitting wheel 3 form; Described centrifugal pump wheel hub, impeller and slitting wheel 4 are arranged in the pump housing 1; Described centrifugal pump wheel hub is made up of cone boss 2, and convection cell play the guiding role well, reduces the impact to centrifugal pump wheel hub, improves the loss that fluid frontal impact convection cell impact force causes simultaneously; On described cone boss 2, be symmetrical arranged 4 slitting wheel 3; Described slitting wheel 3 and cone boss 2 integrally castings; Bowlder outside gold machining, cutting edge self-assembling formation; Without special processing, manufacturing efficiency is higher; The direction of the cutting edge of described slitting wheel 3 is consistent with vane rotary direction, has ensured the cutting efficiency of slitting wheel.
Edge length and height by 4 described slitting wheel reduce one by one from four slitting wheel of first slitting wheel to the; Can, in fully cutting, reduce convection cell acting, reduce air horsepower, improve the efficiency of pump.
Embodiment recited above is described preferred implementation of the present utility model, not design of the present utility model and scope is limited.Do not departing under the prerequisite of the utility model design concept; various modification and improvement that related domain ordinary person makes the technical solution of the utility model; all should drop into protection domain of the present utility model; the technology contents of the utility model request protection, has all been documented in claims.
