Abstract

The invention relates to an impeller which comprises an impeller body. A shaft hole is formed in the center of the impeller body, a plurality of blades which are uniformly distributed around the shaft hole are arranged on the upper end surface of the impeller body and comprise first blades and second blades, the first blades and the second blades are fixedly connected with one another to form the V-shaped blades with angles A and are of integral structures, and the center line of the upper end surface of each first blade and a tangent line of the inner diameter side of the shaft hole are collinear. The impeller has the advantages that the impeller is simple in structure and is provided with the blades with the certain angles, accordingly, water spinning force can be increased, the water spinning efficiency can be improved, and the performance of a water pump in the aspects of high lift, high flow and efficiency can reach 80% at least.

Description

A kind of impeller
Technical field
The present invention relates to liquor pump field, relate in particular to a kind of impeller.
Background technique
In high-floor feedwater, high building fire-proof, petrochemical industry, petroleum pipeline conveying etc., all to use large flow, high-lift and high efficiency pump, the technical performance that traditional pump has is that flow and lift are inversely proportional to, be flow when large lift little or when high-lift flow little, and one of vitals that determines pump performance is exactly impeller.Impeller is widely used in daily life and industrial production as the indispensable parts of water pump etc., and for different applicable situations and the size of drainage capacity, impeller is designed to many different structures.
Summary of the invention
The object of this invention is to provide a kind of impeller, to overcome, do not have a kind ofly can produce the impeller that lift is directly proportional to flow.
The object of the invention is to be achieved through the following technical solutions:
A kind of impeller, comprise wheel body, the center of described wheel body has axis hole, the upper-end surface of described wheel body is provided with around the equally distributed some wheel blades of described axis hole, described wheel blade comprises the first leaf and the second leaf, described the first leaf is fixedly connected with angled with the second leaf be the V-arrangement of A, and described the first leaf and the second leaf are structure as a whole, the end face center line of described the first leaf and the tangent line conllinear of shaft hole diameter.
Further, the angular range of described A is greater than 130 degree and is less than 170 degree, is preferably 150 degree.
Further, long limit, the both sides of the end face figure of described the first leaf and the second leaf is parallel lines.
Further, the length of described the first leaf is greater than the length of the second leaf.
Further, the sectional shape of described the first leaf and the second leaf is rectangle.
Further, the sectional shape of described the first leaf and the second leaf is the right-angled trapezium that edge lengths is less than base length.
Further, the quantity of described wheel blade is 4 to 16, is preferably 9.
Further, the lower end surface of described wheel body is provided with from the stiffening rib of the outside scattering of axis hole, between described axis hole and the second leaf, is provided with annular stiffening rib.
Beneficial effect of the present invention is: this blade wheel structure is simple, has adopted the wheel blade with several angle, thereby strengthens drying strength and efficiency, can make water pump reach high-lift, high flow capacity, efficiency reaches more than 80% performance.
Accompanying drawing explanation
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the plan view of the impeller that wheel blade cross section is right-angled trapezium described in the embodiment of the present invention;
