Abstract
The utility model discloses a water pump assembly for an automobile, which comprises a water pump body (2), an impeller shaft (3), a water seal assembly (4) and an impeller (5). A water suction chamber (8) is formed between the water pump body and the impeller. The impeller (5) is separated from the water suction chamber (8) through an embedded ring (6) arranged on an inner inclined plane of the water pump body, and an integrated water suction chamber is formed. The water pump body and the embedded ring are in a split structure. The water pump body can be formed by pressure casting technique. When cooling water enters the water suction chamber of the water pump, the integrated water suction chamber structure of the water pump is formed because of the embedded ring of the water suction chamber. Therefore, the water suction chamber of the water pump has the same function as a water pump of the water pump formed by casting technique. The water pump assembly for the automobile has high production efficiency and rate of finished products of parts and good in economic benefit.
Description
Technical field
The present invention relates to a kind of motor car engine water cooling system, specifically relate to a kind of auto pump assembly.
Background technique
At present, the water pump body material of auto pump assembly is mainly made by cast iron or aluminum alloy, and the aluminum alloy water pump body is divided into two kinds of technologies of die casting and casting.The manufacturing equipment of die casting is the aluminium alloy compression casting machine, and its manufacturing efficiency is high, and the finished part rate is high, and good in economic efficiency, the main shortcoming of this technology is that part must keep the little outside of inner chamber big, and promptly mould can carry out the withdrawing pattern separation.The technological advantage of casting is the restriction that part does not receive shape, but that its shortcoming is a manufacturing efficiency is low, and the finished part rate is also low, deficiency in economic performance.The water pump body of band suction chamber says to have the all-in-one-piece pump housing (containing the edge circle) from structure, so can only carry out Foundry Production, its product cost is high, does not have price advantage, and product does not have competitive ability on market.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and the auto pump assembly that provides a kind of its aluminum alloy water pump physical efficiency to adopt extrusion process to make.
The object of the invention is realized through following technological scheme: a kind of auto pump assembly; Comprise water pump body, impeller shaft, water-sealed component, impeller; Form suction chamber between water pump body and the impeller; Said impeller and suction chamber are separated by through being contained in the water pump body edge circle on the inclined-plane, constitute complete suction chamber with this.Described water pump body is split-type structural with the edge circle.
After adopting structure of the present invention, water pump body can adopt the extrusion process manufacturing to accomplish, when cooling water enters into the pump sump chamber; Because the existence of this suction chamber edge circle; Constituted a complete pump sump cell structure, so identical with the pump sump chamber function of casting technique making, its manufacturing efficiency is high; The finished part rate is high, and is good in economic efficiency.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the present invention is made further detailed description.
Fig. 1 is the structural representation of auto pump assembly of the present invention.
Fig. 2 is the structural representation of edge circle among Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 2.
Embodiment
Can know referring to figs. 1 through Fig. 3; Auto pump assembly of the present invention; Comprise land 1, water pump body 2, impeller shaft 3 (containing bearing is one), water-sealed component 4, impeller 5; Form suction chamber 8 between water pump body 2 and the impeller 5, said impeller 5 and suction chamber 8 are separated by through being contained in the water pump body edge circle 6 on the inclined-plane, constitute complete suction chamber with this.Described water pump body 2 is a split-type structural with edge circle 6.Wherein, form suction chamber 8 between said water pump body 2 and edge circle 6, the impeller 5, promptly on the said water pump body 2 and and impeller 5 between locate to be equipped with edge circle 6, constitute a plane of suction chamber through the edge circle.
Wherein, have two imports 9, two outlets 10 on the water pump body 2; One end of water pump body 2 is equipped with land 1, and its other end is equipped with cover plate 7; Said edge circle 6 and water pump body 2 compress through press machine, and both junctions are coated with 717 type resin glues at this, and it is solid and reliable that the compression fit magnitude of interference is that 0.15-0.3 guarantees.
Claims (3)
1. auto pump assembly; Comprise water pump body (2), impeller shaft (3), water-sealed component (4), impeller (5); Form suction chamber (8) between water pump body (2) and the impeller (5); It is characterized in that: said impeller (5) and suction chamber (8) are separated by through being contained in the water pump body edge circle (6) on the inclined-plane, constitute complete suction chamber with this.
2. auto pump assembly according to claim 1 is characterized in that: described water pump body (2) is a split-type structural with edge circle (6).
3. auto pump assembly according to claim 2; It is characterized in that: form suction chamber (8) between said water pump body (2) and edge circle (6), the impeller (5); Promptly said water pump body (2) go up and and impeller (5) between locate to be equipped with edge circle (6), constitute a plane of suction chamber through the edge circle.
