Abstract
The utility model discloses a channel type impeller with helical blades. The channel type impeller comprises a conical hub (1), the conical hub extends axially from a suction hole, and the radius of each blade is increased gradually, thereby forming a helical channel. The impeller on a suction cover can produce helical propelling effect to deliver high-viscosity media. Compared with a general centrifugal pump, the channel type impeller with helical blades has the advantages of no blockage, fine performance and fine nondestructive property.
Description
Technical field
The utility model relates to a kind of blade wheel structure, especially relates to a kind of channel-type impeller with helical blade.
Background technique
The main working parts of centrifugal pump is impeller and pump case, impeller normally by 5～7 arc shaped blades and before, back circular cover constitutes.Behind pump startup, impeller drives high speed rotating by axle, and interlobate liquid also must be along with rotation.Under action of centrifugal force, liquid is thrown to outer rim and is obtained energy from the impeller center, so that leaving impeller outer edge enters the volute pump case at a high speed.In spiral case, liquid changes part kinetic energy into static energy again owing to the expansion gradually of runner is slowed down, and flows into discharge conduit with higher pressure at last, and delivering to needs the place.When liquid flows to outer rim by the impeller center, be formed centrally certain vacuum in impeller, liquid just is pressed in the impeller continuously, constantly is inhaled into and discharges.But for the conveying of high viscosity medium, the impeller of this structure is owing to the inhalation power deficiency, and no plugging performance and non-destructive all can not be satisfactory.
Summary of the invention
The purpose of this utility model provides a kind of channel-type impeller that can produce the band helical blade of screw propulsion effect.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises hub body, it is characterized in that described hub body is taper, is prolonged vertically by suction port on the cone hub body, and the radius of blade increases gradually, forms helical duct.
The structure that the utility model adopts, the impeller of suction cover part can produce the screw propulsion effect, can the transfer of highly viscous medium.Compare with general centrifugal pump, have following beneficial effect: 1, no plugging performance is good; 2, non-destructive is good; 3, can transfer of highly viscous liquid.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
Among the figure 1, hub body
Embodiment
By accompanying drawing as can be known, the channel-type impeller of this band helical blade comprises hub body 1, it is characterized in that described hub body 1 is taper, the utility model impeller adopts double-spiral structure, its sped structure, prolonged vertically by suction port on cone hub body 1, the radius of blade increases gradually, forms helical duct.The pump case housing is made up of suction cover and spiral case two-part, and the impeller of suction cover part can produce the screw propulsion effect as screw pump.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other multi-form variation or changes on the basis of the above description.Here need not also can't give all mode of executions exhaustive, and these belong to conspicuous variation or the change that spirit of the present utility model draws and still are among the protection domain of the present utility model.
Claims (1)
1. the channel-type impeller with helical blade comprises hub body, it is characterized in that described hub body is taper, is prolonged vertically by suction port on the cone hub body, and the radius of blade increases gradually, forms helical duct.
