Description
Technical field
It is specifically a kind of centrifugation impeller of pump with negative pressure blade the invention belongs to centrifuge pump technical field.
Background technology
Centrifugal pump is to be rotated using impeller and make water that centrifugal movement occur and driven come work, the impeller of rotation 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.
Why centrifugal water pump, which can draw water, is rotated by the high speed of water pump vane, and low-pressure area, water are formed in pump case
In water pipe is inhaled under the action of atmospheric pressure, and therefore one of key condition of centrifugal water pump normal work is water pump and water inlet
Manage air tight, while also not inspiration air.But in actual use, since flooded condition such as does not know at the factor, in water pump
Often there is a small amount of air, largely effect on pump working efficiency.
The content of the invention
Goal of the invention：The purpose of the present invention is for the deficiency in current technology, there is provided it is a kind of with negative pressure blade from
Heart impeller of pump, its blade are hollow-core construction, and inside has a negative pressure, and upstream face is waterproof ventilated membrane, and impeller connection is very during work
Sky pump, can produce 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 with the impeller, and the impeller center connects impeller axle, the impeller, blade and leaf
The generally hollow-core construction of wheel shaft composition, is provided with opening, the blade upstream face is covered in impeller shaft end and blade upstream face
It is stamped upstream face cover layer.
One kind as this programme is improved, and the upstream face cover layer is breathable waterproof membrane.
One kind as this programme is improved, and is additionally provided with support plate in the blade, and support plate is by blade backwater towards meeting
The water surface is set, and to support upstream face cover layer, venthole is provided with the support plate.
One kind as this programme is improved, and the impeller, blade and impeller axle are made using 3D printing technique.
Beneficial effect：A kind of centrifugation impeller of pump with negative pressure blade of the present invention, impeller, blade and impeller axle
The generally hollow-core construction 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 by the way that but air can pass freely through, in use, impeller axle can connect transmission
Equipment, impeller shaft end connection vacuum pump, 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 cover from upstream face in water pump, which passes through, enters blade interior, by vacuum
Pumping is walked, so as to ensure do not have air in water pump.
Blade interior is provided with support plate and is used to upstream face cover layer be made, and prevents upstream face cover layer by water impact quilt
Damage.
The impeller, blade and impeller axle are made using 3D printing technique, the centrifugal pump with negative pressure blade
Complicated with blade wheel structure, conventional fabrication processes are not easy to produce, and 3D printing technique can solve the problems, such as this.
