Abstract

A bionic centrifugal pump comprises a motor, a connecting shaft, a shell, a vane, grids and rib plates, wherein the surface of the vane is a structure which simulates feather on a wing of a bird or the grid form of sharkskin, the inner surface of the shell (3) and the surface of the vane are in the grid shape, a single grid is a pit body in which a tongue shape, a disk shape or a triangle body is cut out on the circular surface or cambered surface, the grids are separated by horizontal and vertical rib plates, the horizontal rib plate is a body in a strip-line shape, the vertical rib plate is a vertical crescent body which is arranged in the bottom of the pit body and is lower than the pit body, therefore the grid can form independent dewatering unit. When eddy in the pit rotates, the eddy force can generate assistant force, thereby improving the efficiency. Water flows on the surface of the pit to form resistance force in the past, and water rubs with water owing to the pit, the friction resistance is reduced, the water flow is fast, the water yield passed in unit time is increased, the efficiency of conveying liquid is improved, and electric energy is saved.

Description

A kind of bionic type centrifugal pump

Technical field

The invention provides a kind of bionic type centrifugal pump of carrying liquid kind.

Background technique

Centrifugal pump is by centrifugal force conveyance fluid engineering goods, crossing centrifugal force by the blade pass of several angle during running goes out FLUID TRANSPORTATION, the design of its blade surface macroscopic view is the streamline of bionic type, but its surface but is level and smooth, has that transfer efficiency is low, the slippage loss is big, high shortcoming consumes energy.

Summary of the invention

A kind of bionic type centrifugal pump of high transfusion efficient is provided.

The utility model is realized in the following way

A kind of bionic type centrifugal pump is to improve at existing centrifugal pump, a new technology of proposition.The blade surface of bionical centrifugal pump is imitative flying bird wing feather or shark skin texture, the evolution in several ten million years of flying bird process, the wind energy power of catching of wing is necessarily very strong, feather macro surface through observing the flying bird wing is level and smooth, its internal structure but be from level to level grid structure, the feather surface is by many hole, windward side bodies near 90 ° of angles, the balance between two forces about the hole body is interior, and the front is near the right angle.A kind of bionic type centrifugal pump is made up of motor (1), connecting shaft (2), housing (3), blade (4), grid (5), gusset (6).Use method stationary housing (3), the blade (4) of machinery respectively in a connecting shaft (2) position of motor (1), housing (3), blade (4) is the shape of grid (5) on the surface, single grid (5) is for cutting out the hole shape body of a ligule, dish shape or triangle body on a disc or cambered surface, there is gusset (6) to separate between each grid, gusset (6) is along the tabular body of the rule setting of air-flow direction and a rule thread like body that intersects with it, hole shape body has a whirlpool system of one's own, makes it to become one by one independently water dumping unit.Upstream face, back side are cheated interior swirling flow when rotated, and vortical force can produce boost, raises the efficiency.Upstream face, the original water of lee face are at its Surface runoff resistance, because the hole exists, and becoming major part is the friction of water and water, surface friction drag diminishes now.

The utility model beneficial effect

1. transfusion fluid efficient improves, the conservation of power energy.2. reduction noise pollution.

Embodiment

A kind of bionic type centrifugal pump blade (4) surface is the feathery structure of imitative flying bird wing, and the grid of the feather of flying bird wing carries out microsection, and the surface is for cutting out the hole shape body of a ligule, dish shape or triangle body.Motor (1) is the commercially available equipment of using at present, for centrifugal pump provides power.Blade (4) is a long circular-arc plate body, and effect is to accept the power rotation to send waterpower.It is fixed on the connecting shaft (2), housing (3), blade (4) is the shape of grid (5) on the surface, single grid (5) is for cutting out a ligule on disc or cambered surface, the hole shape body of dish shape or triangle body, grid (5) is separated by horizontal with perpendicular gusset (6), horizontal gusset is the thread like body of a rule, perpendicular gusset is in shape body bottom, hole, be lower than the crescent moon of the setting one by one body of hole shape body, the height of perpendicular gusset is the 10-60% of the hole shape body degree of depth, like this, hole shape body is a whirlpool body one by one, the horizontal out-of-date resistance of gusset thread like body air stream is little, perpendicular gusset is embedded in bottom in the whirlpool hole, both can reduce air flow resistance, can keep the grown form in whirlpool hole again.Shape body back, hole is a concave arc surface backward, about face be vertical plane, housing (3), blade (4) all are the hole shape bodies of grid (5) shape with water engaging surface, housing (3) is made up of two lobes, a lobe is an end sealing centre cirque body with holes.The internal surface of housing (3), blade (4) upstream face, back side are cheated interior vortex when rotated, and vortical force can produce boost.Originally water is at its Surface runoff resistance, because the hole exists, and 99% surface becomes the friction of water and water, and surface friction drag diminishes, water flow velocity is accelerated now, and the water yield that the unit time is flow through increases, and improves saving power than present centrifugal pump water liquor charging body efficient.

Claims

1. a bionic type centrifugal pump is by motor (1), connecting shaft (2), housing (3), blade (4), grid (5), gusset (6) is formed, it is characterized in that: bionic type centrifugal pump, its housing (3) is made up of two lobes, one lobe is a cirque body with holes in the middle of the end sealing, the internal surface of housing (3), blade (4) is the shape of grid (5) on the surface, single grid (5) is for cutting out a ligule on disc or cambered surface, the hole shape body of dish shape or triangle body, grid (5) is separated by horizontal with perpendicular gusset (6), horizontal gusset is the thread like body of a rule, perpendicular gusset is in shape body bottom, hole, be lower than the crescent moon of the setting one by one body of hole shape body, the height of perpendicular gusset (6) is the 10-60% of the hole shape body degree of depth.
