Abstract
The utility model discloses a centrifugal pump impeller, which relates to fluid machinery, and comprises a hub, a blade, a front cover plate and a rear cover plate. The centrifugal pump impeller is characterized in that auxiliary power slots are uniformly distributed on the end portions of the outer sides of the front cover plate and/or the outer cover plate, and the depths of the auxiliary power slots become shallow gradually from the direction of an outer radial axial lead of an impeller. The centrifugal pump impeller is arranged in a centrifugal pump, the impeller is driven by a pump shaft to rotate at work, the auxiliary power slots assist the blade to work when the blade works, and the centrifugal pump is big in head and high in efficiency. The performance of the centrifugal pump is increased, and the impeller in the same specification is wide in applicable scope of performance.
Description
Technical field
The utility model relates to fluid machinery, says in detail it is a kind of centrifugal pump impeller that lift increases, efficient is higher that can make centrifugal pump.
Background technique
We know, comprise the pump housing, pump shaft and impeller for delivery of the centrifugal pump of fluid.Existing centrifugal pump impeller comprises wheel hub, blade, front shroud and back shroud, and centrifugal pump impeller is connected with pump shaft by wheel hub, and blade is arranged on the wheel hub, and front shroud, back shroud are arranged on the both sides, front and back of blade and coupled; This centrifugal pump impeller only has the acting of blade fluid medium, and centrifugal lift of pump is little, efficient is low.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of centrifugal pump impeller that lift increases, efficient is higher that can make centrifugal pump is provided.
The technological scheme that the above-mentioned the deficiencies in the prior art that solve the utility model adopt is:
A kind of centrifugal pump impeller comprises wheel hub, blade, front shroud and back shroud, it is characterized in that front shroud and or the back shroud outboard end be evenly equipped with auxiliary acting groove, the degree of depth of auxiliary acting groove shoals to direction of axis line gradually from impeller outer diameter.
Rectangular or the circular arc of auxiliary acting groove described in the utility model radially be arranged on front shroud and or back shroud on.
The angle of the center line of the auxiliary acting groove described in the utility model and the Normal direction of impeller is between 0-45 °.
The utility model is installed in when working in the centrifugal pump, and the pump shaft impeller is rotated, and auxiliary acting groove auxiliary blade does work in the time of the blade acting, and centrifugal lift of pump is large, efficient is high.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Centrifugal pump impeller as shown in the figure, comprise wheel hub 5, blade 4, front shroud 3 and back shroud 2, its structure is same as the prior art, characteristics of the present utility model are: front shroud 3 and/or back shroud 2 external circumferential are evenly equipped with auxiliary acting groove 1, the degree of depth of auxiliary acting groove 1 shoals to direction of axis line gradually from impeller outer diameter, as can be seen from the figure groove is rectangular radially is arranged on front shroud and the back shroud in auxiliary acting, auxiliary acting groove also can be circular arc and radially be arranged on front shroud and or the back shroud, and effect was better when the radian on two radial strut limits of the auxiliary acting of circular arc groove was identical.The degree of depth of same auxiliary acting groove shoals to direction of axis line gradually from impeller outer diameter.Only evenly be provided with auxiliary acting groove on the front shroud external circumferential, also can evenly be provided with auxiliary acting groove on the back shroud external circumferential, can also front shroud and the back shroud external circumferential on all evenly be provided with respectively the auxiliary groove that does work.The utility model is installed in the centrifugal pump, and during work, the pump shaft impeller is rotated, auxiliary acting groove auxiliary blade acting in the time of the blade acting, and centrifugal lift of pump is large, efficient is high.Centrifugal pump performance increases, and same specification impeller Applicable scope is wide.
Claims (3)
