Abstract
The utility model discloses a water pump cover with an improved structure. Flow guiding bars with bending shapes distributed unevenly with an installation hole as the center are arranged on the inner wall surface of the water pump cover. Due to the fact that a plurality of flow guiding bars with the bending shapes are additionally arranged on the water pump cover, rotary liquid flow around an active water seal is guided to the water seal purposely, the water seal is cooled down, functions of reducing speed and increasing pressure are achieved, and the cavitation is avoided, the phenomenon that the dry friction or the dry-and-wet alternating friction happens on the water seal are avoided. The water pump cover with the improved structure is simple in structure, low in production cost, suitable for various kinds of mechanical seals and various kinds of satisfactory high elastic water seals , capable of improving the overall performance of the water pump and prolonging the service life of the water pump .
Description
Technical field
The utility model relates to a kind of automobile component, especially a kind of water pump cover of architecture advances.
Background technique
Automobile with centrifugal cooling water pump to the aspects such as small volume, quality are light development, and with this understanding, causing the Centrifugal water pump compact structure, axial dimension is less, liquid flow volume space around the water seal in the Centrifugal water pump is extremely narrow and small, and the cooling of water seal is caused difficulty; Water seal lacks the cooling of liquid stream easily at run duration, thereby dry friction occurs or do the problem that wets the alternation friction and lost efficacy.
Simultaneously, because the development of water seal, the SIC-SIC water seal relies on the advantage of more anti-cooling liquid impurity, obtains the approval in market, but the shortcomings such as its easy generation dry friction have also caused numerous users' complaint.
Moreover for improving the life-span of Centrifugal water pump, the elastic force between the dynamic and static ring of mechanical seal is more and more higher, in the inadequate situation of liquid stream condition of water seal periphery, also can cause the situations such as water seal generation dry friction.
More than the generation of every kind of situation, with causing very soon the inefficacy of the Centrifugal water pump that motor uses on the automobile, cause engine water temperature too high, can not normally move, bring inconvenience to the user.
Summary of the invention
The utility model provides a kind of water pump cover of architecture advances, has solved water seal and dry friction has occured during high speed operation easily or do the problem that wets the alternation friction and lost efficacy.
The technical solution of the utility model is: a kind of water pump cover of architecture advances is characterized in that: the internal face of water pump cover is provided with the bent type guide rib of non-uniform Distribution centered by mounting hole.
Beneficial effect: because set up many bent type guide ribs at the internal face of water pump cover, with the autotelic guiding water seal of rotated flowing liquid around the operating water seal, water seal is cooled off, can also play to it effect of reduction of speed supercharging, avoid this part generation cavitation, directly avoid water seal generation dry friction or done the generation that wet alternation rubs, the utility model, simple in structure, fabricating cost is low, be fit to various types of mechanical sealings and various satisfactory high elasticity water seal, improved water pump overall performance and life-span.
Description of drawings
Fig. 1 is plan view of the present utility model.
Fig. 2 is the vertical view cutaway drawing of C-C among Fig. 1.
Embodiment
As illustrated in fig. 1 and 2, a kind of water pump cover of architecture advances, the internal face of water pump cover 1 are provided with 1 ~ 3 bent type guide rib 2 of non-uniform Distribution centered by mounting hole.The bending direction of this song type guide rib is identical with the bent type direction of the blade of the impeller at water seal top; The height of bent type guide rib preferably is not less than water seal dynamic and static ring junction plane height; Be positioned near the curve guide rib the water seal the termination direction preferably directly and the cylindrical of water seal dynamic and static ring junction plane tangent, cause water seal dynamic and static ring inhomogeneous cooling to avoid inhomogeneous bent type guide rib structure.
Claims (1)
1. the water pump cover of an architecture advances, it is characterized in that: the internal face of water pump cover is provided with the bent type guide rib of non-uniform Distribution centered by mounting hole.
