Increased using rear blade surface roughness, easily lead to blade partial failure, impeller bounce is occurred and increase, generate irregular vibration
And a large amount of noise, accelerate the overall efficiency decline for leading to pump, it is entirely ineffective to eventually lead to equipment.
The blade wheel structure of existing centrifugal pump is in low-flow high-lift, because impeller is mostly disc-shape, impeller
On width of blade is relatively narrow and leptophyllous reason, cause impeller disc friction larger.In addition, due to blade quantity compared with
Few, each impeller only has 3-4 pieces of blade substantially, and divergence loss is very big between blade, is easy to exist again in vacuum side of blade low-pressure side
Whirlpool blocks runner.
Utility model content
The present invention provides a kind of centrifugal pump impeller structure, to solve the impeller disc friction of centrifugal pump in the prior art
Greatly, divergence loss is greatly between blade, vacuum side of blade low-pressure side whirlpool occurs and the technology of instability of flow blocking runner is asked
Topic.
The present invention solves above-mentioned technical problem and adopts the technical scheme that: a kind of centrifugal pump impeller structure, design feature
Be: including chassis, chassis outer circle is uniformly provided with gap, and chassis is provided centrally with round catcher, is uniformly provided with length on chassis
Blade and short blade, the end of linear leaf connect with the outer circle on chassis, and the origin or beginning of short blade connects with circle catcher, linear leaf with
The bending direction of short blade is identical.
Further, the quantity of the linear leaf, short blade and gap is equal.
Further, the shape on the side of the gap is identical.
Further, the chassis is plum blossom shape.
Further, straggly before and after the end of the origin or beginning of the linear leaf and short blade.
Further, gap is equipped between the origin or beginning of the linear leaf and the end of short blade.
The beneficial effects of the utility model are: the utility model by using quincunx chassis, can reduce in this way and liquid
The contact area of medium reduces disc friction, improves the efficiency of pump.In addition, there are tiny between linear leaf and short blade
Gap, when the pump is operated, the on high-tension side medium of linear leaf working face can flow to linear leaf back side low-pressure side by gap, make to come into leaves
The pressure of piece back side low-pressure side rises, and prevents the formation of whirlpool herein, effectively avoids instability of flow blocking runner, thus
Improve the efficiency of pump.
