Abstract
The utility model relates to the field of water pumps and provides a water pump for an annular impeller. The water pump comprises a connecting plate, a bearing, a pump body, a water seal component, the impeller and a rotating shaft. The connecting plate is the eccentric connecting plate, a mounting hole is formed in an arced surface on one side of the eccentric connecting plate, far away from the center of the same, the connecting plate is disposed at one end of the rotating shaft, each vane of the impeller is of an irregular quadrilateral structure provided with point outer ends and is the annular vane with certain radian, the vanes are disposed at the other end of the rotating shaft, the water sealing component with certain radian is arranged between the pump body and the impeller, and the overall strength of the water pump can be effectively improved by cooperating with the structure of the pump body. The water pump has the advantages of simple structure, stable using performance and long service life.
Description
Technical field
The utility model relates to a kind of water pump, relates in particular to a kind of ring-type impeller water pump.
Background technique
Existing cooling water pump impeller for automobile engine is mostly made up of plastic impeller body and metallic impeller core, but this kind of plastic impeller body is due to the reason of its material and structure, easily occur that at spoke place the bulk strength of product can not meet the demands completely along the phenomenon of spoke hole cracking.
Model utility content
The technical problems to be solved in the utility model is, for the deficiencies in the prior art, and provides a kind of ring-type impeller water pump.
The utility model solves the technological scheme that its technical problem adopts: a kind of ring-type impeller water pump is provided, comprise land, bearing, the pump housing, water-sealed component, impeller and rotating shaft, described land is eccentric land, it is apart from being provided with mounting hole in the side cambered surface far away of the center of circle, described land is installed on one end of described rotating shaft, the blade of described impeller is irregular quadrilateral structure, its outer end is sharper, and described blade is the annular blade with certain radian, be installed on the other end of described rotating shaft, between the described pump housing and described impeller, be provided with described water-sealed component, described water-sealed component is set in described rotating shaft.
The utility model further preferred version is: between a side inwall of the described pump housing and described bearing, be provided with multiple seal rings.
The utility model further preferred version is: described seal ring comprises two, the setting of evenly arranging.
The utility model further preferred version is: the described pump housing is " protruding " font structure.
Implement the technical solution of the utility model, have following beneficial effect: the utility model is set to have the annular impeller of certain radian by impeller, the structure between the cooperation pump housing can effectively increase the bulk strength of water pump; The utlity model has advantage simple in structure, that usability is stablized and grown working life.
