Description
Technical field
The utility model relates to sewage axial-flow pump submersible pump technical field, especially relates to a kind of cutting axial-flow pump with cutting blade.
Background technique
The pump that the active force that axial-flow pump produces liquid by the blade of spinning roller impeller makes liquid carry along axial direction, have vertical, horizontal, inclined and tubular several.Axial-flow pump also, usually as submersible pump, is worked in encroached water.Blowdown axial-flow pump is mainly used in the sewage of draining.Owing to carrying out work in sewage, there is dirt in present blowdown axial-flow pump, in the process of axial-flow pump work, dirt can enter in the pump housing along with sewage in sewage, easily cause pump body to stop up, thereby damage the phenomenon of pump.
Traditional blowdown axial-flow pump is at pump housing afterbody, to add one to consider dirty net, places the larger dirt of volume and enters figure pump body.But, during wheel rotation, can be adsorbed onto and consider dirty on the net considering dirty net dirt around, when dirt covers completely, to consider dirtyly when online, pump body easily forms vacuum, cannot effluent, motor also can be hot, and significantly reduced the working life of motor.
Summary of the invention
Problem to be solved in the utility model be to provide a kind of simple in structure, pollution discharge capability good, can effectively protect the cutting axial-flow pump of the pump housing and motor.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of cutting axial-flow pump is provided, comprise the pump housing, be arranged on the pump case of described pump housing afterbody, axially be arranged on the pump shaft of described pump body and be arranged on impeller and the guide wheel on described pump shaft, described impeller and guide wheel are positioned at the inside of described pump case, it is characterized in that: described guide wheel comprises cylinder and is circumferentially distributed in the blade on described cylinder outer wall, the bottom of described blade is provided with cutting blade perpendicular to described blade, described cutting blade is along with described guide wheel rotates, between the described pump housing and described pump case, be provided with oil cylinder seat, between described oil cylinder seat and described pump case, be also provided with annular stationary knife seat, described annular stationary knife seat inner circumference is to being provided with knife rest, the top of described knife rest is provided with the ledger-plate coordinating with described cutting blade perpendicular to described knife rest, described ledger-plate and cutting blade positioned opposite.
Further, described blade has six, and described blade is curved and by described cylinder, to cylinder outside, extended all evenly settings centered by the axis of described cylinder of described blade.
Further, described cutting blade is fixed by screws on described blade.
Further, described knife rest has four, and is evenly distributed on ring in described annular stationary knife seat.
Further, described ledger-plate is fixed by screws on described knife rest.
Advantage and the beneficial effect that the utlity model has are: the blade of guide wheel is provided with the cutting blade rotatablely moving with guide wheel, and on the knife rest of annular stationary knife seat, be provided with the ledger-plate matching with cutting blade, and ledger-plate and cutting blade are oppositely arranged, by ledger-plate, coordinate with the cutting of cutting blade, dirt larger in sewage can be cut into fragment; In annular stationary knife seat, be equipped with knife rest, between knife rest, leave space, facilitate sewage flow.The utlity model has simple in structure, pollution discharge capability good and the advantage that can effectively protect the pump housing and motor.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As Figure 1-Figure 4, the utility model provides a kind of cutting axial-flow pump, comprise the pump housing 1, be arranged on the pump case 4 of the described pump housing 1 afterbody, be axially arranged on the pump shaft 2 of the described pump housing 1 inside and be arranged on impeller 5 and the guide wheel 6 on described pump shaft 2, impeller 5 and guide wheel 6 are positioned at the inside of pump case 4.
Guide wheel 6 comprises cylinder 61 and is circumferentially distributed in the blade 62 on cylinder 61 outer walls, and blade 62 has six, and six blades 62 are circumferentially uniformly distributed, and blade 62 is curved, and is extended to cylinder 61 outsides by cylinder 61.The bottom of blade 62 is provided with cutting blade 63 perpendicular to blade 62, and cutting blade is fixed on blade 62 by screw 10, and cutting blade 63 is along with guide wheel 6 rotations.
Between the pump housing 1 and pump case 4, be provided with oil cylinder seat 3, between oil cylinder seat 3 and pump case 4, be also provided with annular stationary knife seat 8, annular stationary knife seat 8 inner circumferences are to being evenly distributed with four knife rests 9, the top of knife rest 9 is provided with the ledger-plate 7 coordinating with cutting blade 63 perpendicular to knife rest 9, ledger-plate 7 is fixed on knife rest by screw 10, and ledger-plate 7 is oppositely arranged with cutting blade 63.
The utility model when in use, pump shaft 2 rotarily drives impeller 5 and guide wheel 6 rotations, under the effect of impeller 5, sewage is sucked to the pump housing 1 inside, and the dirt in sewage by guide wheel 6 time, coordinates with the cutting between ledger-plate 7 by cutting blade 63, dirt is cut into fragment, then by the space between knife rest 9, enter pump body, effectively prevent that the dirt of large volume is blocked in the pump housing 1, make pollution discharge capability better.
