Description
Technical field
The utility model relates to a kind of automobile engine cooling water pumps, belong to the improvement of 493 automobile engine cooling water pumps
Technical field.
Background technique
The impeller of existing 493 automobile engine cooling water pump is using the molding impeller of steel plate punched, and the impeller is due to punching
Technique limitation is pressed, there are the following problems:
1, punching press impeller is transferred because of blade and is formed, and disc defect, impeller is usually full-open type, and impeller inner flow passage is with volute chamber
It communicates, is also easy to produce the hydraulic losses such as leak, reflux and vortex.
2, the shaft shoulder of punch forming impeller generally has step, not smooth, is also easy to produce the hydraulic losses such as shock.
3, the dimensional accuracy of punching press impeller is not high, and rigidity is not strong, easily causes the fit clearance between blade and volute uneven
And inner hole connect unreliable etc. with bearing, and water pump is caused to generate vibration, the problems such as performance is unstable, and connection reliability is poor.
Utility model content
The purpose of this utility model seeks to solve working efficiency present in existing 493 automobile engine cooling water pump
It is low, the problem of poor reliability, provide a kind of automobile engine cooling water pump.
The utility model to achieve the goals above, adopts the following technical scheme that
A kind of automobile engine cooling water pump, has pump case, be respectively equipped on pump case bearing position, water seal position, helical flow path,
Mounting hole, leak-off chute and seal groove are equipped with shaft connecting bearing at the bearing position of pump case, are equipped on the left axle neck of shaft connecting bearing
Water seal is installed at drive flange, the right axle neck middle part dress of shaft connecting bearing and the water seal position of pump case, leaf is installed on right axle neck
On the inner hole of wheel；
Impeller is equipped with the disc of the shaft shoulder and umbrella shape, and the inner hole of horn shape is equipped in disc.
Further, be symmetrically equipped with eight antecurvature arc type blades on disc around axial line, blade water outlet with
For circumferencial direction at right angle, blade water inlet and blade slopes at right angle, disc is equipped with symmetrical two balance holes in axle center.
Further, the impeller is the semi-open type structure of casting and forming.
The utility model has the beneficial effects that
Compared with existing 493 automobile engine cooling water pump, the utility model hot investment casting impeller is set the utility model
There is the umbrella cover disc of smooth smoothness, overcome water flow caused by punch forming impeller disc defect and the step shaft shoulder and be obstructed, flows back
The problems such as vibration is big, connects poor rigidity, and precision is low, antecurvature arc face blade improves pump head and working efficiency, this is practical
It is novel preferably to solve existing pump working low efficiency, the problems such as performance is unstable, and connection reliability is poor.
