Description
Technical field
The present invention relates to immersible pump and its part field, more particularly, to a kind of impeller of pump device.
Background technology
The speed of current suction and discharge determines the impeller of the operating efficiency, at present immersible pump of immersible pump when blade rotates
Structure is only drained by the blade of distortion to current, but because the direction of current is polytropism, this spline structure is still
The loss of flow energy can be caused, and then influence the lift of pump.
The content of the invention
The problem to be solved in the present invention is to provide a kind of impeller of pump dress for reducing stream power loss, improving diving pump lift
Put.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of impeller of pump device, including annular seating
Plate and circular cover, the middle part of the cover plate are vertically provided with axle sleeve, and one end of the axle sleeve passes through the centre bore of the seat board, institute
The annular abutment portion that centre bore is provided around on the inside of seat board is stated, the annular recessed of centre bore is provided around on the inside of the butting section
Groove, the lower end of the annular groove are provided with drainage face, and the drainage face is the helicoid centered on the axle sleeve, the drainage
The initiating terminal in face is connected with the upper end of the axle sleeve, and the end in the drainage face is connected with the cover plate, the seat board with it is described
The multiple arcs blade of centre bore is provided around between cover plate, the one end at the inner edge of the blade is located on the seat board,
The other end at the inner edge of the blade is located on the cover plate, and the outer end of the blade extends to the outer of the seat board.
Further, the yawing moment of the blade is consistent with the rotation direction direction in the drainage face.
Further, the end in the drainage face is connected with the inner edge of the blade.
Further, water inlet is formed between the axle sleeve and the butting section, water outlet is formed between the blade is adjacent
Mouthful.
Further, the upper end of the annular groove is provided around the reinforcement of the centre bore, and the one of the reinforcement
End is connected with the axle sleeve, and the other end of the reinforcement is connected with the inwall of the butting section.
The present invention has the advantage that is with beneficial effect：Current are flowed into from water inlet, and drainage is flowed into along annular groove
Face, annular groove form the fluid course of flow inlet, energy loss when current have just enter into impeller are reduced, then via spiral
Shape drainage goes downstream, and the delivery port outflow finally formed from arc shaped blade, this process complies with flow direction, reduces current stream power
Loss, increased so as to the impulse force of current, the lift of pump improves；Reinforcement is disposed around the position of centre bore, to pump in work
Firm effect is played during work, improves the service life of pump.
