Abstract
The present invention discloses a kind of centrifugation impeller of pump with negative pressure blade, including impeller, equally distributed blade is provided on the impeller, the impeller center connects impeller shaft, the generally hollow structure of the impeller, blade and impeller shaft composition, impeller shaft end and blade upstream face are provided with opening, the blade upstream face is covered with upstream face cover film.When the centrifugation impeller of pump work with negative pressure blade, blade is hollow structure, and inside has negative pressure, and upstream face is waterproof ventilated membrane, and impeller connects vacuum pump when work, can generate negative pressure in blade interior, extract air in water pump out.
Description
Technical field
The invention belongs to be centrifuged pump technical field, specifically a kind of centrifugation impeller of pump with negative pressure blade.
Background technique
Centrifugal pump is to be rotated using impeller and make water that centrifugal movement occur come work, and the impeller of rotation drives in pump case
Water does high speed rotary motion, and water occurs centrifugal movement, is thrown toward impeller outer edge, and the runner through volute pump case flows into the pressure water of water pump
Pipeline.
It is the high speed rotation for relying on water pump vane why centrifugal water pump, which can draw water, and low-pressure area, water are formed in pump case
Be inhaled under the action of atmospheric pressure the key condition that therefore centrifugal water pump works normally of in water pipe first is that water pump and water inlet
Manage air tight, while also not inspiration air.But in actual use, due to the factors such as flooded condition is uncertain, in water pump
Often there is a small amount of air, largely effect on pump working efficiency.
Summary of the invention
Goal of the invention: the purpose of the present invention is for the deficiency in current technology, provide it is a kind of with negative pressure blade from
Heart impeller of pump, blade are hollow structure, and inside has negative pressure, and upstream face is waterproof ventilated membrane, and impeller connection is true when work
Sky pump can generate negative pressure in blade interior, extract air in water pump out.
Technical solution: to achieve the above object, the present invention provides a kind of centrifugation impeller of pump with negative pressure blade, including
Impeller, equally distributed blade is provided on the impeller, and the impeller center connects impeller shaft, the impeller, blade and leaf
The generally hollow structure of wheel shaft composition, is provided with opening in impeller shaft end and blade upstream face, the blade upstream face covers
It is stamped upstream face cover film.
As a kind of improvement of this programme, the upstream face cover film is breathable waterproof membrane.
As a kind of improvement of this programme, it is additionally provided with support plate in the blade, support plate is by blade backwater towards meeting
Water surface setting, to support upstream face cover film, is provided with venthole in the support plate.
As a kind of improvement of this programme, the impeller, blade and impeller shaft are made using 3D printing technique.
The utility model has the advantages that a kind of centrifugation impeller of pump with negative pressure blade of the present invention, impeller, blade and impeller shaft
The generally hollow structure of composition, blade upstream face and impeller shaft end have opening, and impeller upstream face is covered with waterproof and breathable
Film, the waterproof ventilated membrane can prevent moisture from passing through, but air can pass freely through, in use, impeller shaft can connect transmission
Equipment, impeller shaft end connect vacuum pump, and the centrifugation impeller of pump with negative pressure blade is in rotary course, vacuum pump work
Make, form negative pressure in blade, the waterproof ventilated membrane that air is covered from upstream face in water pump, which penetrates, enters blade interior, by vacuum
Pumping is walked, to guarantee in water pump without air.
Blade interior is provided with support plate for upstream face cover film to be made, and prevents upstream face cover film by water impact quilt
Damage.
The impeller, blade and impeller shaft are made using 3D printing technique, the centrifugal pump with negative pressure blade
With blade wheel structure complexity, conventional fabrication processes are not easy to produce, and 3D printing technique can solve this problem.
