Abstract
The utility model relates to an engine water pump vane, including the axle bed, the center department of axle bed is provided with the pump shaft mounting hole, the lateral surface equipartition of axle bed has at least three blade, the both sides face of blade is provided with first side cap board and second side cap board, first side cap board with the radius of second side cap board with the radius of blade is the same, first side cap board with all be provided with the water inlet on the second side cap board, the water inlet with the blade intercommunication, with the surface that blade direction of rotation carried on the back mutually, it is near blade end is provided with protruding structure. Through the protruding structural design on the blade, increased blade end's weight, the inertial force of impeller tip increases, and this inertial force also offers the liquid that enters into in the impeller simultaneously, has increased the kinetic energy of liquid, has improved the work efficiency of water pump.
Description
Technical field
The utility model belongs to pumping equipment field, refers to a kind of water pump vane for engine cooling water circulation especially.
Background technique
Traditional water pump vane is all centered by water pump axle bed, the axle bed of water pump is evenly equipped with blade, produces centrifugal force by the rotation of blade in water pump cover, realize water inspiration blade by centrifugal force, and by the High Rotation Speed of blade, water is discharged from water delivery side of pump.
The blade structure of conventional art is all the ends to blade from the axle bed of water pump, the thickness of blade reduces gradually, in the case, blade in working order time, necessarily provide corresponding power by power source, low to the utilization ratio of energy, and then the working efficiency of traditional water pump is lower, energy loss is large.
Model utility content
The purpose of this utility model proposes improvement opportunity scheme to traditional impeller, by the impeller of the technical program, when being applied in traditional water pump cover, can improve the working efficiency of water pump.
The utility model is achieved through the following technical solutions:
A kind of engine water pump impeller, includes axle bed; The center of described axle bed is provided with pump shaft mounting hole; At least three blades are evenly equipped with at the outer side surface of described axle bed;
The first side cover plate and the second side cover plate is provided with in the bi-side of described blade; Described first side cover plate is identical with the radius of described blade with the radius of described second side cover plate;
Described first side cover plate and described second side cover plate are provided with water intake, and described water intake is communicated with described blade;
On the surface opposing with described blade rotary direction, nearly described blade tip is provided with protruding structure.
Described protruding structure is hemisphere, and the diameter of described protruding structure is less than the width of described blade tip.
The height of described protruding structure is the spacing 1/6-1/4 of adjacent described blade tip.
The arc be provided with to described blade rotary direction at the dual-side of the end of described blade bends.
The beneficial effects of the utility model are:
The water pump vane of the application, by the protruding structure design on blade, add the weight of blade tip, under identical angular velocity, the inertial force of impeller end increases, this inertial force is also supplied to simultaneously and enters into water in impeller or other liquid, namely adds the kinetic energy of water or other liquid, improves the working efficiency of water pump.

Description of reference numerals
1 first side cover plate, 2 second side cover plates, 3 blades, 4 protruding structures, 5 axle beds, 6 pump shaft mounting holes, 7 water intakes, 31 arc bendings.
Embodiment
Describe the technical solution of the utility model in detail by the following examples, following embodiment is only exemplary, only can be used for explaining and the technical solution of the utility model being described, and can not be interpreted as being the restriction to technical solutions of the utility model.
The utility model provides a kind of engine water pump impeller, as depicted in figs. 1 and 2, includes axle bed 5; The center of described axle bed 5 is provided with pump shaft mounting hole 6; When assembling, pump shaft being inserted in this pump shaft mounting hole 6, and fixing with key pin; At least three blades 3 are evenly equipped with at the outer side surface of described axle bed 5; The quantity of blade is determined as required, and the blade of usual water pump is odd number.Axle bed and blade to be processed as one structure by casting, existing by fine finishing manufactures such as lathes.
The first side cover plate 1 and the second side cover plate 2 is provided with in the bi-side of described blade 3; Described first side cover plate 1 is identical with the radius of described blade with the radius of described second side cover plate 2; Arrange cover plate in the both sides of blade, can improve the working efficiency of blade, prevent in wheel rotation process, the water between impeller and pump case or liquid can not be brought into the water outlet of water pump, and produce power loss.
Described first side cover plate 1 with described second side cover plate 2 are provided with water intake 7, and described water intake 7 is communicated with described blade 3;
On the surface opposing with described blade 3 sense of rotation, nearly described blade tip is provided with protruding structure 4.
Described protruding structure 4 is hemisphere, and the diameter of described protruding structure 4 is less than the width of described blade tip.
The height of described protruding structure 4 is the spacing 1/6-1/4 of adjacent described blade tip.
The dual-side of the end of described blade 3 is provided with the arc bending 31 to described blade rotary direction.Arc bending 31 has two advantages in this application, one is the intensity that can improve blade, and another is in the course of the work, and the liquid that arc bending can drive to blade applies the power in the middle part of impeller, improve the working efficiency of impeller, and prevent the generation of reflux phenomenon.Reflux refers in blade rotary process, the liquid of a part is not along with the action of blade is transported to the water outlet of water pump, but by from leaking through next blade or other blade place between blade and the housing of water pump, and this partially liq is still provided with energy, what these energy and blade were supplied to liquid can measure consumption.Therefore, reflux can reduce the water-outlet quantity of Centrifugal water pump.
Although this technical solution of the utility model is described in detail, those skilled in the art is all clear, by the amendment carried out the technical program, replacement and modification etc., and all should within the protection domain of the application.
