Abstract
The utility model relates to an impeller chamber structure of a large-sized upright axial flow pump, which is added with an abrasion-proof stainless steel bush. The impeller chamber structure comprises an impeller chamber. The impeller chamber structure is characterized in that the center position of the impeller chamber is provided with a cylindrical groove, an abrasion-proof stainless steel band is welded in the cylindrical groove of the impeller chamber, and the outer side face of the abrasion-proof stainless steel band is a spherical face. The utility model has the advantage that the service life of the impeller chamber can be greatly increased, thereby prolonging the service life of the large-sized upright axial flow pump.
Description
Technical field
The utility model relates to a kind of blade wheel chamber structure, and particularly a kind of large-sized vertical-type axial-flow pump adds blade wheel chamber's structure of abrasion-proof stainless steel lining.
Background technique
Large-sized vertical-type axial-flow pump blade wheel chamber is cast steel structure (as Fig. 1) at present, and the intermediate portion of blade wheel chamber is spherical.Because blade wheel chamber is the core area of whole water pump, impeller is at this high speed rotating, and driving high-pressure medium rotates in blade wheel chamber, to causing very big wearing and tearing along the wheel rotation zone in the blade wheel chamber, because the acquisition cost of large-sized vertical-type axial-flow pump is very high, therefore, therefore be necessary to solve the problem that is lowered in working life of the large-sized vertical-type axial-flow pump that blade wheel chamber's wearing and tearing are caused in case blade wheel chamber's wearing and tearing will cause whole water pump to scrap.
Summary of the invention
The purpose of this utility model is to solve the medium-and-large-sized vertical-type axial-flow pump of prior art blade wheel chamber because the existing easy generation wear problems of cast steel provides a kind of blade wheel chamber's structure that adds anti-wearing liner.A kind of blade wheel chamber's structure that adds anti-wearing liner of the utility model design comprises blade wheel chamber, and it is characterized in that: the center portion of blade wheel chamber is a cylindrical groove, is welded with the abrasion-proof stainless steel band in the cylindrical groove of blade wheel chamber, the outer side surface spherical of abrasion-proof stainless steel band.The utility model has the advantages that the working life that can increase blade wheel chamber greatly, thereby prolong the working life of large-sized vertical-type axial-flow pump.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic representation
Accompanying drawing 2 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise blade wheel chamber 1 among the figure, it is characterized in that: the center portion of blade wheel chamber 1 is a cylindrical groove 2, is welded with abrasion-proof stainless steel band 3 in the cylindrical groove 2 of blade wheel chamber 1, the outer side surface spherical of abrasion-proof stainless steel band 3.
Owing to abrasion-proof stainless steel band 3 is welded in the center portion of the blade wheel chamber 1 that worn and torn by wheel rotation one, therefore promoted the wear resistance of the blade wheel chamber 1 of cast steel structure greatly, thereby is improved the working life of whole large-sized vertical-type axial-flow pump.
Claims (1)
1. the blade wheel chamber's structure that adds anti-wearing liner comprises blade wheel chamber, it is characterized in that: the center portion of blade wheel chamber is a cylindrical groove, is welded with the abrasion-proof stainless steel band in the cylindrical groove of blade wheel chamber, the outer side surface spherical of abrasion-proof stainless steel band.
