Abstract
The utility model relates to an impeller for a liquid pump, which forms a disc shape. The utility model is provided with a plurality of vanes, and impeller grooves are respectively formed between every adjacent vanes; the width of each vane is greater than the width of each impeller groove and the depth of each vane. The utility model has the advantage of big output pressure.
Description
Technical field:
The utility model relates to a kind of part of liquid pump, relates in particular to a kind of impeller of radially flow of fluid pump.
Background technique:
At present, radially the impeller of flow of fluid pump is generally at the impeller groove that is provided with on the disking body between several blades and the blade and constitutes, the side of the blade of prior art is made of two little cambered surfaces of radius of curvature difference, the degree of depth of blade is generally greater than width, the width of blade is less than the width of impeller groove, be generally about 1: 5, the radially flow of fluid pump of this structure impeller has the bigger characteristics of flow, but its delivery pressure is lower, as the increase that is directly proportional of supercharging delivery pressure flow, thereby power of motor is increased exponentially, be not suitable for high-lift occasion.
Summary of the invention:
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, and the impeller of the big radially flow of fluid pump of a kind of delivery pressure is provided.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the liquid pump impeller is a disking body, is provided with several blades thereon, constitutes the impeller groove between the adjacent blades, and the width of described blade is greater than the degree of depth of the width and the blade of impeller groove.
Useful technique effect of the present utility model is: because the width of blade greater than the degree of depth of the width and the blade of impeller groove, makes the output fluid passage diminish, thereby under the situation that increases delivery pressure, do not make flow become big, reach the effect that reduces power.Thereby the radially flow of fluid pump of this impeller has the advantage that delivery pressure is big, flow is little, power is low.
Description of drawings:
Fig. 1 structural representation of the present utility model
Embodiment:
Below in conjunction with drawings and Examples the utility model is further described:
As shown in the figure: the liquid pump impeller is a disking body 1, is provided with 5 (being generally 3-8) blades 2 thereon, and is uniform at circumferencial direction, constitutes impeller groove 3 between the adjacent blades, and the width of described blade 2 is greater than the degree of depth of the width and the blade 2 of impeller groove 3.The neutral position width of described blade is 2-3 a times of impeller groove neutral position width.The neutral position width of described blade is 5-8 a times of depth of blade.
Claims (4)
