Abstract
The utility model discloses a kind of impeller with back blade, in structure, it is set at the wide back blade every the back blade of several conventional narrows, the riser of one wide back blade of arranged for interval, impeller in the back blade.The influence of the impeller without irregular riser protrusion that there is wide back blade of the utility model so that the working efficiency of impeller increases.Fluid flowing caused by back blade is more smooth, thus preferably balances axial force.The stability for improving centrifugal pump keeps work more safe and efficient.
Description
Technical field
The utility model is related to a kind of impeller, specifically a kind of impeller with back blade.
Background technology
Centrifugal pump has wide range of applications, and is referred to as " heart " of modern industry.The stability for centrifuging pump operation, is always to grind
Study carefully the problem of personnel pay close attention to for a long time.Axial force balance is a key factor of centrifugal pump even running, and people pass through to impeller
Improvement, learn impeller cover addition back blade can play the role of balancing axial thrust, reduce pump chamber pressure.In addition, the back of the body
The shape of blade can also influence the pump external characteristics entirely pumped.
During the actual casting of impeller, the front shroud or back shroud that riser are placed on impeller are needed.Back blade is rigid
Fortunately front and rear cover plate adds, and back blade is usually all very narrow, and in the casting process of the impeller of addition back blade, riser position can dash forward
Towering one piece of boss of appearance, and the later stage is difficult processing.Such impeller, boss caused by riser can influence the flowing of fluid,
Reduce the function of back blade, or even lowers the performance of whole pump.
Utility model content
The purpose of this utility model is just to provide a kind of impeller with back blade, is influenced with solving existing impeller riser
The problem of whole pump performance.
The utility model is realized in this way：
A kind of impeller with back blade, every several conventional narrow back blades, arranged for interval in the back blade
The riser of one wide back blade, impeller is set at the wide back blade；The height of wide back blade where the riser and its
Its narrow back blade height is concordant.
The utility model uniformly arranges several wide back blades in back blade, while keeping the streamline of blade
Property.The width of wide back blade is equivalent to the several narrow back blades of merging and therefore provides placement location for the riser of casting process.
After the completion of pump vane casting, the protrusion of the position of riser is polished flat, to ensure to balance axial force of impeller balance, is not broken
The overall flow of bad fluid, and then avoid the pump external characteristics for influencing entirely to pump.
Under above-mentioned technical proposal, the utility model can be achieved：
In impeller with back blade, one wide notopodium is set every two conventional narrow back blades in the back blade
Piece.
The utility model is by combining the adjustment of notopodium plate shape with the selection of riser position, active balance impeller
Axial force avoids influencing pump external characteristics.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings, but the explanation does not constitute and appoints to the utility model
What is limited.
As shown in Figure 1, the impeller 3 with back blade, cloth is spaced in back blade every two conventional narrow back blades 1
A wide back blade 2 is set, the riser of impeller is set at the wide back blade, after the completion of pump vane casting, by riser
The protrusion of position polishes flat, and keeps the height of the wide blade where riser concordant with other blades.In Fig. 1, in back blade
Every two conventional narrow back blades, one wide back blade is set.The width of wide back blade is about the two of the width of conventional narrow back blade
Times or three times.
Compared to the impeller for not staying riser position before, the impeller with wide back blade of the utility model, which avoids, does not advise
The then influence of riser protrusion so that the working efficiency of impeller increases.Because fluid flowing caused by back blade is more smooth, thus
Preferably balance axial force.The stability for improving centrifugal pump keeps work more safe and efficient.
Claims (2)
1. a kind of impeller with back blade, which is characterized in that every several conventional narrow back blades in the back blade,
The riser of one wide back blade of arranged for interval, impeller is set at the wide back blade；Wide back blade where the riser
Height is concordant with other narrow back blade height.
2. the impeller with back blade according to claim 1, which is characterized in that in the back blade often every two
It advises narrow back blade and one wide back blade is set.
