The technical problems to be solved in the utility model is realized using following technical scheme: a kind of electronic water pump thrust button,
Including the thrust button main part with assembly through-hole, drainage trough, the drainage trough are opened up on the end face of the thrust button main part
For helical structure slot.
Preferably, the drainage trough is less than in the bore close to assembly throughhole portions close to thrust button main part marginal portion
Bore.
Preferably, the drainage trough is clock wise spirals rotation direction.
Preferably, the inlet portion of the drainage trough forms arc transition.
Preferably, several and several drainage grooved ring assembly through-hole distributions are arranged in the drainage trough.
Preferably, several drainage troughs are that ring assembly through-hole is uniformly distributed.
Preferably, the cross sectional shape of the thrust button main part is convex shape structure.
Preferably, the inlet portion of the assembly through-hole forms cone structure.
Compared with prior art, the utility model has the beneficial effects that in the electronic water pump course of work, due to thrust button
On drainage trough be helical structure slot, therefore, coolant liquid will pump to thrust button center, in pumping procedure, liquid compression after
Pressure rise can make to be bonded end face between thrust button and bearing and form the liquid film with certain rigidity, can be with by the liquid film
So that thrust button and bearing face is in contactless state, dry friction occurs so as to be effectively prevented bearing and thrust button, has
The degree of wear of thrust button and bearing is alleviated to effect, and reduces operating noise, be conducive to extend electronic water pump uses the longevity
Life.
