Description
[technical field]
The present invention relates to a kind of water pump technology, specifically a kind of water pump vane curved surface flange blade.
[background technology]
Currently, punching type water pump in daily life be widely used in production, most critical of the impeller as water pump
Building block, development develop into punching press pattern by original casting pattern.Existing punching press pump impeller blade pattern is mostly single
Blade welds front and rear cover plate, though changing cast member rough surface is also easy to produce the factors such as stomata, and it is aobvious to the intensity aspect of blade
Some are weak, and when single blade makes welding, is easily deformed, and welds and there was only seamed edge contact, welds poor location, welding less than
Or dislocation.
[invention content]
Present invention aim to solve above-mentioned deficiency, and a kind of water pump vane blade is provided, by impeller blade edge
It blade and carries out the space curved surface that flange forms one fixed width with front shroud of impeller, back shroud of impeller, impeller port ring intersection edge,
And the place cylindrical surface of the flange and front shroud of impeller, back shroud of impeller and impeller port ring fits, strong through flange rear blade
Degree greatly enhances, and welding is unlikely to deform, and welding is had good positioning, and welding will not misplace.
A kind of water pump vane blade, including impeller blade 1, front shroud of impeller 5, impeller rear cover are designed to achieve the above object
Plate 6 and impeller port ring 7, the impeller blade 1 are equipped with blade choma flange 2 with 7 junction of impeller port ring, and the blade choma turns over
Side 2 is the space curved surface of one fixed width, and the impeller blade 1, which fits to constitute with the cylindrical surface of impeller port ring 7, is bonded curved surface A,
The impeller blade 1 is equipped with blade front shroud flange 3 with 5 junction of front shroud of impeller, and the blade front shroud flange 3 is certain
The space curved surface of width, the blade front shroud flange 3, which fits to constitute with front shroud of impeller 5, is bonded curved surface B.
The impeller blade 1 is equipped with blade back shroud flange 4 with 6 junction of back shroud of impeller, and the blade back shroud turns over
Side 4 is the space curved surface of one fixed width, and the blade back shroud flange 4, which fits to constitute with back shroud of impeller 6, is bonded curved surface C.
The present invention compared with the existing technology, due to impeller blade junction be equipped with curved surface flange, these curved surface flange with
Front shroud of impeller, back shroud of impeller, impeller port ring fit completely, have greatly reinforced blade strength, and welding is unlikely to deform, welding
When due to contact surface it is big, be easy to weld, have good positioning, avoid seamed edge poor location welding less than blade or dislocation the phenomenon that, solution
Determined welding single blade intensity difference, it is yielding the problems such as, be worthy of popularization.
[description of the drawings]
Fig. 1 is the impeller blade schematic diagram of the present invention；
Fig. 2 is that the impeller blade of the present invention is welded into impeller schematic diagram；
Fig. 3 is that the impeller blade of the present invention is welded into partial sectional view after impeller；
In figure：1, impeller blade 2, blade choma flange 3, blade front shroud flange 4, blade back shroud flange 5, leaf
Take turns front shroud 6, back shroud of impeller 7, impeller port ring.
[specific implementation mode]
The present invention is made below in conjunction with the accompanying drawings further explained below：
As illustrated in the accompanying drawings from 1 to 3, the present invention includes impeller blade 1, front shroud of impeller 5, back shroud of impeller 6 and impeller port ring 7,
The impeller blade 1 is equipped with blade choma flange 2 with 7 junction of impeller port ring, and the blade choma flange 2 is one fixed width
Space curved surface, the impeller blade 1 and the cylindrical surface of impeller port ring 7 composition that fits be bondeds curved surface A, the impeller blade 1 and
5 junction of front shroud of impeller is equipped with blade front shroud flange 3, and the blade front shroud flange 3 is the space curved surface of one fixed width,
The blade front shroud flange 3, which fits to constitute with front shroud of impeller 5, is bonded curved surface B, the impeller blade 1 and back shroud of impeller
6 junctions are equipped with blade back shroud flange 4, and the blade back shroud flange 4 is the space curved surface of one fixed width, after the blade
Cover board flange 4, which fits to constitute with back shroud of impeller 6, is bonded curved surface C.Fitting curved surface A, B, C of the present invention has greatly reinforced blade
Intensity, welding are unlikely to deform, and since contact surface is big when welding, are easy to weld, be had good positioning, and avoid the welding of seamed edge poor location not
The phenomenon that blade or dislocation.
The present invention is simultaneously not limited to the embodiments described above, other any Spirit Essences and principle without departing from the present invention
Changes, modifications, substitutions, combinations, simplifications made by lower, should be equivalent substitute mode, be included in the protection model of the present invention
Within enclosing.
