Abstract
The utility model provides an impeller of centrifugal pump, including apron and a plurality of blade, the center department of apron is equipped with the shaft hole, and axially the pore size distribution is on the apron for a plurality of blades, and every blade constitutes by inducer and export section, the junction of inducer and export section forms alpha's obtuse angle, the export section is rectilinear form, and the central extension line of every blade export section is all crossing with the central point of apron. The export line type of the aforesaid technical scheme through changing the plain vane exports the form that the section changed the prismatic blade into with the blade, and all the other line types remain unchanged, just so can combine the advantage of prismatic blade and the advantage of plain vane, can improve the lift under the prerequisite that does not change centrifugal pump overall structure, simultaneously again can the not notable reduction of guarantee efficiency.
Description
Technical field
The utility model relates to a kind of centrifugal pump impeller.
Background technique
Blade many employings plain vane of traditional rate revolution centrifugal pump impeller, although compare with prismatic blade, plain vane efficiency is higher, and because the exit installation angle of plain vane is less than prismatic blade, therefore the lift of plain vane is relatively low.When not changing blade line style, lift is improved further if think, can only by increasing impeller diameter, or width of increasing export, but the structure of the pump housing also will be changed accordingly like this, not only increase design cost, centrifugal pump structure becomes larger simultaneously, too increases material and manufacture cost.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of without the need to increasing blade wheel structure size, can ensure high efficiency and high-lift centrifugal pump impeller in the same old way.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of centrifugal pump impeller, comprise cover plate and multiple blade, the center of described cover plate is provided with axis hole, around axis hole distribution on the cover board, each blade is formed by inducer and outlet section multiple blade shroud, and the joint of described inducer and outlet section forms the obtuse angle of α °, described outlet section is rectilinear form, and the elongated central line of each blade exit section is all crossing with the central point of cover plate.
Preferably, the length of the inducer of described blade is greater than the length of outlet section.
In one embodiment, the inducer of described blade is arc shape.
In one embodiment, the inducer of described blade is rectilinear form.
In one embodiment, the inducer of described blade is variable angle spiral.
In one embodiment, the value of described α ° is 136 °.
In one embodiment, the quantity of described blade is 10.
In one embodiment, described blade is installed on the cover board by screw.
In one embodiment, described blade is installed on the cover board by rivet.
Technique scheme is by changing the outlet line style of plain vane, change blade exit section into straight-vaned form, all the other line styles remain unchanged, so just the advantages of straight-vaned advantage and plain vane can be got up, lift can be improved not changing under the integrally-built prerequisite of centrifugal pump, simultaneously again can the not obvious reduction of guaranteed efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of centrifugal pump impeller as shown in Figure 1, comprise cover plate 1 and 10 blades 2, the center of described cover plate 1 is provided with axis hole 3, 10 blades 2 are arranged on cover plate 1 around axis hole 3 by screw or rivet, each blade 2 is formed by inducer 21 and outlet section 22, the length of inducer 21 is greater than the length of outlet section 22, the joint of inducer 21 and outlet section 22 forms the obtuse angle of α °, in the present embodiment, the value of α ° is 136 °, described outlet section 22 is rectilinear form, described inducer 21 can be arc shape or rectilinear form, usually variable angle spiral can be adopted, the elongated central line of each blade exit section 22 is all crossing with the central point of cover plate 1.
