Abstract
The utility model relates to a water pump impeller comprising a disk-shaped wheel disk and vanes arranged on the wheel disk, wherein an axle hole is formed in the surface center of the wheel disk; the vanes comprise a group of short vanes and a group of long vanes which are uniformly arranged on the surface of the wheel disk at intervals and are arc-shaped vanes, and the radian of the short vanes is slightly greater than that of the long vanes. The long vanes and the short vanes of the water pump impeller are different in length and uniformly arranged on the wheel disk at the intervals, and each vane is arc-shaped, so that the hydraulic efficiency of the impeller is greatly improved, the water flow driven by the impeller is increased, the lift of a water pump is improved, and the application range is wide.
Description
Technical field
The utility model relates to a kind of water pump vane, belongs to water pump manufacturing technology field.
Background technique
Water pump is being widely used in daily life, agricultural and industrial production, lift is that water pump is pumped the increment of unit weight liquid from pump inlet to pump discharge place energy, be exactly the liquid-column height that water pump is pumped liquid in brief, therefore, lift is an important indicator of water pump; Along with the development of technique and the progress of technology, also more and more higher to the lift requirement of water pump; The impeller of tradition water pump is comprised of blade and wheel disc, and blade is straight lamellar body, is aplysia punctata and is evenly distributed on wheel disc along the axis hole of taking turns disk center, although this impeller is made simple, but its poor fluidity, make the lift of water pump less, directly cause the efficiency of water pump not high.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of compact structure, reasonable is provided, and can improve the water pump vane of pump head.
The purpose of this utility model is achieved by the following technical solution: comprise a plate-like wheel disc and be arranged on the blade on described wheel disc; Described sheave surface center is provided with axis hole; Described blade comprises one group of short blade and group leader's blade, and these two groups of blades are disposed in an evenly spaced relation in described sheave surface; Described linear leaf and short blade are arc shaped blade, and the radian of described short blade is slightly larger than the radian of described linear leaf.
As preferably, be provided with at least one keyway on described axis hole.
As preferably, described keyway is the flat key groove.
As preferably, described linear leaf, short blade and wheel disc all are made into integration.
As preferably, described impeller surface also is provided with a copper layer.
The beneficial effects of the utility model are: the length of linear leaf and short blade differs, evenly interval is arranged on wheel disc, and every blade is arc shape, make the hydraulic efficiency of impeller be greatly improved, and increased the flow that impeller drives water, improved the lift of water pump, Applicable scope is wider.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: as shown in Figure 1, comprise a plate-like wheel disc 1 and be arranged on the blade 2 on described wheel disc 1; Described wheel disc 1 centre of surface is provided with axis hole 3; Described blade 2 comprises one group of short blade 21 and group leader's blade 22, and these two groups of blades are disposed in an evenly spaced relation in described wheel disc 1 surface; Described linear leaf 22 and short blade 21 are arc shaped blade, and the radian of described short blade 21 is slightly larger than the radian of described linear leaf 22, two groups of blades mix use, make the hydraulic efficiency of impeller effectively be promoted, the flow of impeller increases, and has improved the lift of water pump.
Be provided with at least one keyway 4 on described axis hole 3; Described keyway 4 is the flat key groove; Described axis hole 3 is connected with the pump shaft of water pump, by keyway 4 and pump shaft, fixes.
Described linear leaf 22, short blade 21 and wheel disc 1 all are made into integration, and have improved the integrity of whole impeller, sound construction, good operation stability.
Described impeller surface also is provided with a copper layer, improves the corrosion resistance of impeller.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
