Abstract
The utility model relates to an automobile cooling water pump, which is composed of a casing, a cover plate, an impeller, a driving member, a sealing member, and a fastening member. The utility model is characterized in that the support frame and the pump body of the traditional water pump are integrated and can be integrally pressed and cast, a sealing gasket is additionally arranged between the bottom of the casing and the cover plate, and the casing and the cover plate are tightly connected by screws. The utility model has the advantages of simple structure, material saving, and good integral sealing property of the water pump.
Description
A kind of water pump, particularly a kind of car combustion engine cooling waterpump.
In the prior art, the production of automobile cooling water pump is a kind of to be major part support, the pump case cast molding of elder generation with water pump, and then it is carried out machining, assembling, the shortcoming of this production is, foundry goods machining allowance is big, and rough surface is difficult to satisfy quality and quantitative requirement during production in enormous quantities; Also having a kind of is that support, pump case are designed to one, make it can die cast, making cover plate in the housing bottom surface with a thin plate then is tightly connected with it, the shortcoming of this production is that cover plate is thin and area occupied is bigger, easy warpage in processing and transportation process, influence being tightly connected of housing and cover plate, directly influence the sealability of auto pump.
The purpose of this utility model is to provide a kind of automobile cooling water pump, the major part of this pump die cast that can be integrated, and surface roughness is good, and its cover plate is not yielding, and combine back water pump overall tightness with housing good.
The purpose of this utility model is to realize like this, automobile cooling water pump is made up of housing, cover plate, impeller, transmission part and Sealing, it is characterized in that pump intake is right cylindrical and communicates with the housing inner chamber, be placed with seal washer between housing and the cover plate, housing and cover plate are fastening by screw.
The cover sheet thickness of automobile cooling water pump is 4-15mm, and cover plate has one with the consistent concave surface of housing spiral case curve shape with casing joint face, and the concave surface degree of depth is 1-12mm.
The angle of inclination of cooling water car pump case water outlet is 0-4 °.
The cooling water car pump closure tightens center and the cover plate both sides close mounting hole place of the position in hole at three ears of cover plate.
Advantage of the present utility model is that auto pump is simple in structure, and easy processing save raw material, and the water pump overall tightness is good.
Description of drawings:
Fig. 1 is an auto pump External view in the prior art.
Fig. 2 is the utility model External view.
Fig. 3 is the cover plate plan view.
Fig. 4 is a cover plate A-A sectional view.
Fig. 5 is the cover plate rear view.
Fig. 6 is the utility model sectional view.
Especially exemplified by an embodiment, in conjunction with the accompanying drawings the utility model is described further below.
As Fig. 1, cooling waterpump support, pump case are two independent parts, and be complex-shaped, and its structure can't die casting, and surplus is big during machining, and efficient is low, the waste raw material.
As Fig. 2, be the utility model External view, as seen from the figure, the utility model is combined into a part with pump case, two parts of support--housing (1), water intake (2) is right cylindrical and communicates with housing (1) inner chamber, and water intake (2) is 0 °, 1 °, 2 °, 3 ° or 4 ° with housing horizontal center line angle of inclination.Housing (1) simple shape can be cast, also can die casting, shorten machining period greatly, and save raw material.
Shown in Fig. 3-5, be cover plate (3) plan view, sectional view and rear view, as seen from the figure, cover plate (3) one side is the plane, another side has a concave surface (4), it is consistent that the shape of concave surface (4) and housing (1) helix shape are wanted, and the degree of depth of concave surface (4) is 1mm, also can be 2,3,4,5,6,7,8,9,10,11,12mm; When being arranged on the cover plate (3) for cooling waterpump and internal-combustion engine assembling, 4 mounting holes (6) use, fastener hole (5) is used for housing (1) and is connected fastening usefulness with cover plate (3), and its position is located near mounting hole (6) in the center and cover plate (3) both sides of (3) three ears of cover plate; Concave surface (7), hole (8) are consistent with the cavity shape of housing relevant position respectively; Cover plate (3) can be cast, but also die cast, and cover plate (3) thickness is that 4mm also can be 5,6,7,8,9,11,13 or 15mm.
Fig. 6 is the utility model assembling view, in conjunction with Fig. 2 as can be known, water outlet assembly (12) is connected with housing (1) side, black box (15) is installed on housing (1) the bore seal end face, transmission part is fixed in housing (1) bearing hole by bearing unit (13), impeller (11) is connected by bolt with pump shaft (10) one ends, wheel ancient (14) is connected by bolt with pump shaft (10) the other end, cover plate (3) has the one side of concave surface (4) to engage with housing (1) bottom, fastening with screw (9), add the sealing of sealing liner between housing (1) and cover plate (3), fastening screw trip bolt (9) quantity is 3,4 or 5.
