Abstract
The utility model relates to the technical field of centrifugal pumps, in particular to a centrifugal pump impeller for a chemical industry. The centrifugal pump impeller for the chemical industry comprises the impeller which is composed of a shaft sleeve, an upper cover plate, a lower cover plate and a guide vane, wherein the lower cover plate is arranged on the shaft sleeve in a sleeved mode, the upper cover plate is arranged above the shaft sleeve, and the upper cover plate and the lower cover plate are connected through the guide vane. The centrifugal pump impeller for the chemical industry is characterized in that an inner hole of the shaft sleeve is a cone-shaped shaft hole, and the diameter of the outer end of the shaft sleeve is larger that the diameter of the inner end of the shaft sleeve. The centrifugal pump impeller for the chemical industry has the advantages of being reasonable in structure, convenient to detach and install, capable of saving time and labor and the like.
Description
Technical field
The utility model relates to the centrifugal pump technical field, specifically a kind of chemical industry centrifugal pump impeller.
Background technique
At present, the medium that carry with centrifugal pump in the chemical plant generally all has corrosivity, corrosive fluid is carried through impeller, this impeller is by axle sleeve, upper cover plate, lower cover plate and guide vane form, be arranged with lower cover plate on the axle sleeve, the axle sleeve top is provided with upper cover plate, be connected through guide vane between upper cover plate and the lower cover plate, inner hole of shaft sleeve is cylindrical, impeller passes pump shaft and is fixedly connected with pump shaft through nut, and its deficiency is: because the inner hole of shaft sleeve of impeller and pump shaft are cylindrical respectively, and gap between the two is very little, be easy to scab between impeller and the pump shaft, get rusty dismounting difficulty when causing changing the interior part of the pump housing.
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 rational in infrastructure, easy accessibility, time saving and energy saving chemical industry centrifugal pump impeller are provided.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of chemical industry centrifugal pump impeller, be provided with impeller, impeller is comprised of axle sleeve, upper cover plate, lower cover plate and guide vane, be arranged with lower cover plate on the axle sleeve, axle sleeve top is provided with upper cover plate, is connected through guide vane between upper cover plate and the lower cover plate, it is characterized in that inner hole of shaft sleeve is the taper axis hole, and axle sleeve outer end diameter is beneficial to dismantle impeller from pump shaft greater than inner diameter, reaches the effect of easy accessibility.
The utility model is owing to adopt said structure, has rational in infrastructure, easy accessibility, the advantage such as time saving and energy saving.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Reference character: impeller 1, axle sleeve 2, upper cover plate 3, lower cover plate 4, guide vane 5, taper axis hole 6, pump shaft 7, tightening nut 8.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in drawings, a kind of chemical industry centrifugal pump impeller, be provided with impeller 1, impeller 1 is comprised of axle sleeve 2, upper cover plate 3, lower cover plate 4 and guide vane 5, is arranged with lower cover plate 4 on the axle sleeve 2, axle sleeve 2 tops are provided with upper cover plate 3, be connected through guide vane 5 between upper cover plate 3 and the lower cover plate 4, it is characterized in that axle sleeve 2 endoporus are taper axis hole 6, and axle sleeve 2 outer end diameters be greater than inner diameter, be beneficial to reach the effect of easy accessibility from pump shaft 7 dismounting impellers 1.
The utility model when mounted, the impeller 1 of pump shaft 7 is installed shaft part and is processed into the taper that matches with the taper axis hole 6 of axle sleeve 2, and impeller 1 is fixed on the installation shaft part of pump shaft 7 through tightening nut 8, when needs are dismantled, only need dismounting tightening nut 8, pump shaft 7 is namely extracted out from the taper axis hole 6 of impeller 1.
The utility model is owing to adopt said structure, has rational in infrastructure, easy accessibility, the advantage such as time saving and energy saving.
