Abstract
A vane with a grooved inlet section comprises a vane. Wherein, a vane end contacts a pump cavity wall. One side of the inlet section of the vane is arranged with a groove along an outline of the vane. A groove structure is positioned at the inlet section of prior vanes by repairing and cutting the vane inlet section without complex vane streamline model design and processing. The vane remarkably improves pump performance, ensures simple and convenient vane processing and operation, reduces cost and enhances pump working performance.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to pump, the particularly impeller blade of pump, and concrete is a kind of blade of inducer fluting.
Background technique:
Blade is the vital part of pump, and the shape and structure of blade has very big influence to the service behaviour of pump.In the prior art, normally adopt and revise the blade sweeping style in order to improve pump performance, though this method can achieve the goal, the sweeping style design difficulty of revising blade greatly, require height, fabricating cost high to blade processing equipment.
Summary of the invention:
The purpose of this utility model provides a kind of blade of inducer fluting, and the blade of described this inducer fluting will solve the sweeping style of blade in the prior art and revise the big technical problem of difficulty.
The blade of this inducer fluting of the present utility model is made of blade, wherein, is provided with groove in the described blade inducer.
Further, described groove is along the external frame setting of blade.
Working principle of the present utility model is: by the inducer at existing blade groove is set, can obtains suitable sweeping style, reach the purpose of improving pump performance, through repairing the blade after cutting, features such as the pressure-flow of pump, efficient-flow all are significantly improved.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is provided with the groove structure by repairing the method for cutting the blade inducer at existing blade inducer, needn't carry out complicated design of blade sweeping style and complicated processing, pump performance is improved significantly, processing of leaves is simple to operation, reduce cost, and improved the service behaviour of pump.
Description of drawings:
Fig. 1 is the structural representation of the blade of inducer fluting of the present utility model.
Embodiment:
As shown in Figure 1, the blade of inducer of the present utility model fluting is made of blade 1, and the cooperation that contacts with pump chamber wall 2 of the end of described blade 1 is provided with groove 3 in the inducer of described blade 1.
Further, described groove 3 is along the external frame setting of blade 1.
Claims (2)
1. the blade of an inducer fluting is made of blade, it is characterized in that: be provided with groove in the described blade inducer.
2. the blade of inducer fluting as claimed in claim 1, it is characterized in that: described groove is along the external frame setting of blade.
