Abstract
The utility model discloses a cooling water pump for an automobile, and relates to a water pump. The cooling water pump comprises a water pump body, an impeller and a water seal, wherein a water inlet hole and a water outlet hole are formed in the water pump body; a blade I is mounted at the front of the impeller; and a blade II is additionally arranged at the back of the impeller. The rotation of the blade II increases the flow velocity of a cooling liquid nearby the water seal, so that the water temperature is reduced, the accumulation of impurities is reduced, and the service life of the water pump is prolonged. The cooling water pump is high in corrosion resistance, simple in structure, low in manufacturing cost, and convenient to popularize and use.
Description
Technical field
The utility model relates to a kind of water pump, particularly a kind of automobile cooling water pump.
Background technique
The effect of water pump is to the cooling liquid pressurization, guarantees that it circulates in cooling system.Motor car engine extensively adopts Centrifugal water pump.When water pump vane rotated, the cooling liquid in the water pump was driven rotation together by impeller, and was thrown toward the edge of water pump cover under action of centrifugal force, produced certain pressure simultaneously, flowed out from outlet pipe then.Pressure descends because cooling liquid is thrown out of in the center of impeller, and the cooling liquid in the radiator flows into the impeller center through intake pipe under the differential pressure action at water pump import and impeller center.Impeller has 6-8 straight radial blade or backward leaning vane usually by the cast iron manufacturing on the impeller.
At present, the water seal mounting type of auto pump mainly contains and is installed in two kinds at impeller front and the impeller back side, be contained in the water seal at the impeller back side, owing to covered by impeller on the structure, when water pump operation, the rotation of impeller can make cooling liquid flow to osculum from the water inlet by impeller, and the cooling liquid of water seal place is little because of the impeller back gap, and the very difficult circulation that realizes cooling liquid, make that the flow velocity of cooling liquid of water seal place is lower, often can't will take away because of heat and some impurity that the water seal friction produces very soon, cause the coolant temperature of water seal place higher relatively, accumulate easily more impurity, the working life of reducing water pump simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of automobile cooling water pump that improves the water pump life-span is provided.
The technological scheme that solves the problems of the technologies described above is: a kind of automobile cooling water pump, comprise water pump body, impeller and water seal, offer water inlet and osculum on the described water pump body, described impeller front is equipped with the blade I, radially has additional 1 ~ 10 blade II 7 at the impeller back side.
Further technological scheme of the present utility model is: described blade II is protruded the height H=1 ~ 2mm at the impeller back side.
Described impeller and blade II are to adopt plastic production.
Because adopt technique scheme, the automobile cooling water pump of the utility model has following beneficial effect:
1. improve the water pump life-span:
Because the utility model increases at the impeller back side blade is arranged, when wheel rotation, cooling liquid to the impeller back side has applied thrust, the centrifugal force of cooling liquid is increased, flow velocity increases, the rotation of blade can throw away the cooling liquid at the impeller back side, the lower cooling liquid of the temperature then relief hole on impeller flows into the water seal installation place, increase the flow velocity of back side cooling liquid, improve near the coolant flow speed of water seal, accelerate the circulation of impeller back side cooling liquid, effectively reduce water temperature, reduce the accumulation of impurity, improve the working life of water pump.
2. anticorrosive:
Cooling liquid in the auto pump has corrosivity, the impeller that cast iron materials is made gets rusty easily, corrodes under the corrosive action of cooling liquid, and impeller of the present utility model and blade are formed by plastic production, has not only avoided problem of rustiness, also light than cast iron, also improved corrosion resistance.
3. simple in structure, cost is low:
The utility model just has additional blade at the impeller back side, and other structures are all constant, and are simple in structure, and fabricating cost is low, is convenient to promote the use of.
Below, be further described in conjunction with Figure of description and the specific embodiment technical characteristics to the automobile cooling water pump of the utility model.
Description of drawings:
Fig. 1: the structural representation of the automobile cooling water pump of the utility model.
Fig. 2: the master of impeller looks sectional view in the automobile cooling water pump of the utility model.
The A of Fig. 3: Fig. 2 is to view.
In above-mentioned accompanying drawing, each label declaration is as follows:
The 1-water pump body, 2-impeller, 3-water seal, 4-water inlet, 5-osculum, 6-blade I, 7-blade II.
The direction of arrow is the direction of coolant flow among Fig. 1.
Embodiment:
A kind of automobile cooling water pump, comprise water pump body 1, impeller 2 and water seal 3, offer water inlet 4 and osculum 5 on the described water pump body 1, described impeller 2 fronts are equipped with blade I 6, radially have additional 7 blade II 7 at impeller 2 back sides, described blade II 7 is protruded the height H=1 ~ 2mm at impeller 2 back sides, and described impeller 2 and blade II 7 are to adopt plastic production, and described impeller 2 and blade II 7 are injected into a whole.
A kind of conversion as present embodiment: the quantity of described blade II can be 1,2,3 or multi-disc.
