Abstract
The utility model relates to a pump impeller which comprises an impeller base and a plurality of vanes; the impeller base comprises a mounting sleeve and a vane plate with diameter of 140mm; a mounting hole is arranged on the mounting sleeve; the outer diameter of the mounting sleeve is 33mm; the diameter of the mounting hole is 15.9mm; the thickness of the vane plate is 3mm; the distance between the other surface of the vane plate mounted with vanes and the mounting surface of the mounting sleeve is 38.5mm; the height of vanes positioned at the circumference of vane plate is 14.5mm; as the height of the circumference contact part of the pump vanes and the vane plate is increased to 14.5mm from 13mm under the condition that the strength of vanes is not affected, the flow rate and pump lift of pump are improved so as to improve the cooling effect of engine.
Description
Technical field
The utility model relates to a kind of impeller, specifically, relates to a kind of water pump impeller that a kind of engine cooling water pump is used.
Background technique
As everyone knows, water pump is one of critical piece of motor, for the circulation of cooling water in the motor provides power, for engine-cooling system provides enough cooling water flow and lifts, and the structures shape of the impeller of water pump the lift and the flow of water pump, the too high intensity that can reduce blade of blade is damaged impeller easily, blade cross short then sometimes can not be for engine-cooling system provides enough flow and lifts, reduce cooling effect.
The model utility content
Problem to be solved in the utility model is at above problem, provides a kind of blade that both can make to keep enough intensity, can improve the flow of water pump and a kind of water pump impeller of lift again.
For achieving the above object, the technological scheme that the utility model adopted is: a kind of water pump impeller, comprise impeller base and several blades, described impeller base comprises that installation sleeve and diameter are the cover plate of 140mm, described installation sleeve is provided with mounting hole, described installation sleeve external diameter is 33mm, described mounting hole diameter is 15.9mm, described cover plate thickness is 3mm, the another side of described cover plate installation blade one side is 38.5mm to the distance of installation sleeve attachment face, and it is characterized in that: the height (h) that described blade is positioned at cover plate excircle place is 14.5mm.
As a kind of optimized project, described blade quantity is 8.
A kind of concrete optimized project, the roulette wheel profile of described blade and the angle of cover plate are 8 °.
The utility model is taked above technological scheme, have the following advantages: because under the situation of the blade strength that does not influence water pump vane, the height h of water pump blade and the cover plate excircle contacting point original 13mm that serves as reasons is increased to 14.5mm, thereby the flow of water pump and lift are improved, and then the cooling effect of motor is improved.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the structural representation that a kind of water pump is used impeller in the utility model;
Accompanying drawing 1 is the right elevation of accompanying drawing 1.
Embodiment
Shown in accompanying drawing 1, accompanying drawing 2, a kind of water pump impeller comprises impeller base 1 and 8 blades 2 that are positioned on the impeller base 1, and impeller base 1 comprises that installation sleeve 11 and diameter are the cover plate 12 of 140mm, installation sleeve 11 is provided with mounting hole 111, and installation sleeve 11 is provided with internal thread with an end that is positioned at cover plate 12.
The roulette wheel profile 21 of blade 2 is 8 ° with the angle of cover plate 12
Because blade 2 is 14.5mm with the height h of cover plate 12 excircle contacting points, has increased 1.5mm than original 13mm, the flow of water pump and lift is improved, and then has improved the cooling effect of motor.
