Description
Technical field
The present invention relates to equipment for liquid transportation field, more particularly to a kind of water pump.
Background technology
With the continuous improvement of economic level, automobile also enters huge numbers of families, with being continuously increased for automobile quantity, for
The requirement of engine also more and more higher, the power of Modern Automobile Engine is increasing, and the technological level of engine is also increasingly
Height, efficient work is simultaneously also for cooling requirements more and more higher.And water pump is one non-for the engine of automobile
Normal important part, it can convey coolant to the cylinder body of engine, and after flowing through cylinder surface by coolant, by cylinder
The heat of body is taken away, and ensures the normal operation of engine with this.Therefore the effect of water pump also increasingly important, water pump is to starting
Machine normal work plays irreplaceable effect.
Existing part water pump is to enter cooling water from the center of pump cover when running, and will be cold from the side face of pump cover
But water is discharged.And during this, due to directly there is larger space between impeller blade and pump cover, so that in impeller
Part cooling water between blade and pump cover will under the boost conditions without impeller blade, and directly with it is cold after pressurization
But it is discharged together after water mixing.So it is easy to make mechanical energy substantial amounts of loss during mixing of cooling water, and not
Beneficial to the lifting of pump head, and easily cause the waste of water resource.
The content of the invention
It is an object of the invention to provide a kind of water pump, it can reduce the damage of cooling water mechanical energy in mixed process
Lose, it is conducive to improving lift.
The present invention above-mentioned purpose technical scheme is that:A kind of water pump, including the pump housing and cover are set
In the pump cover on the pump housing, the center of the pump cover, which is carried, carries delivery port, the pump housing on water inlet, the side face of the pump cover
Interior to carry motor, the output shaft of the motor carries some blades in being arranged in pump cover on an impeller, the impeller, the impeller
The cover body of truncated cone-shaped is provided with, the center of the cover body is provided with through hole, and the through hole is corresponding with water inlet, and the cover body is in leaf
Dug to pump cover side at the edge of wheel side.
It is most cold so after cooling water is entered in pump cover from water inlet by using above-mentioned technical proposal
But water will be entered in the space between impeller and cover body from the through hole at cover body center, afterwards cooling water will by impeller from
The effect of mental and physical efforts and increase pressure, and it is final from delivery port outflow to be thrown toward delivery channel.
And the cooling water in cover body is introduced into, it will be flowed along the surface of cover body.Here, because cover body is close
The edge of impeller side is dug to pump cover side, so that the cooling water being thrown out of along cover body surface, will along away from
The lateral movement of the pump housing one, and moisture film together is formed between cover body and pump cover, so as to be conducive to prevention to be introduced into cover body and impeller
Between cooling water, enter cooling water of the delivery channel with being pressurized and mix, and reduce the lift of final conveying cooling water.
Preferably, the through hole size and water inlet it is equal sized.
, so can be in the case where ensureing cover body normal rotation by using above-mentioned technical proposal, again can be compared with the day of one's doom
Degree ground makes cooling water enter between cover body and impeller, so as to be conducive to improving the charging efficiency of cooling water.
Preferably, the pump cover is provided with bulge loop with the edge corresponding section that cover body is dug.
By using above-mentioned technical proposal, the setting of bulge loop can play the work of stop to the cooling water thrown away by cover body
With, and the width of moisture film can be also reduced, so as to be conducive to improving moisture film to non-intensified cooling water inhibition.
Preferably, the end of the output shaft carries the spacing ring for being provided with annular groove, the annular groove and being used for abutting cover body.
By using above-mentioned technical proposal, after impeller is set on output shaft, spacing ring can play limit to impeller
The effect of position, prevents conveying axis when impeller is rotated, impeller spins off from output shaft.
Preferably, being provided with the spacing ring can make spacing ring be inserted into the gap in annular groove.
By using above-mentioned technical proposal, such spacing ring can be easily snapped onto in annular groove by gap, so as to carry
High installation effectiveness between impeller and conveying axis.
Preferably, the blade is set along same circumferential skewing, and the spacing between the blade is from impeller
The center of circle gradually increases to the edge direction of impeller.
By using above-mentioned technical proposal, be so conducive to the cooling water entered between cover body and impeller, can obtain
The sufficiently long acceleration distance of blade, so as to be conducive to improving speed of the cooling water during being thrown out of, is conducive to increase to cool down
The hydraulic pressure of water.
Preferably, the blade is obliquely installed towards the one end in the impeller center of circle from impeller to pump cover direction.
By using above-mentioned technical proposal, it so ensure that blade has stronger shear action to cooling water, so that
Be conducive to improving the transfer efficiency of water pump.
Preferably, the cover body is provided with the caulking groove matched with blade towards blade side.
By using above-mentioned technical proposal, the fix tightly soundness between blade and cover body is so on the one hand advantageously ensured that,
On the other hand it ensure that the sealing effectiveness between impeller and cover body, it is ensured that the cooling water entered between cover body and impeller can
All it is pressurized.
Preferably, being circumferentially evenly distributed with some fin on the pump cover.
By using above-mentioned technical proposal, because fin can increase the area of pump cover, so that in the mistake of water pump operation
Cheng Zhong, fin can play effective heat sinking function, so as to advantageously ensure that the normal operation of water pump.
In summary, the invention has the advantages that:
1st, because the edge of cover body is dug to cover body side, so as to can be thrown toward along the cooling water of cover body surface flow
Pump cover, so that moisture film together can be formed between the edge and pump cover of cover body, so as to prevent part cooling water from not passing through
Cross impeller pressurization in the case of and the cooling water with having pressurizeed mix, cause final output cooling water pressure reduction;
2nd, linked together, on the one hand can be so improved between blade and cover body by way of intercalation between blade and cover body
Degree of being connected firmly, on the other hand also ensure that the cooling water entered between impeller and cover body all can fully be increased
Pressure;
3rd, blade be into close to one end of impeller central it is inclined, so be easier cutting is played a part of to cooling water so that
Cooling water is flowed more easily along blade.
