Abstract
The utility model discloses a wear-resisting multistage centrifugal pump impeller, including impeller body, both ends are equipped with the choma installation department and the stator sealing ring installation department that are used for installing choma and stator sealing ring respectively around impeller body, have the wear-resisting material layer along spraying plating on the surface of choma installation department and stator sealing ring installation department. The utility model discloses a set up the wearing substance layer on impeller body, make the impeller more wear-resisting to make its original efficiency who keeps the pump for a long time, the part adds wear-resisting material and compares the cost reduction with whole change wear-resisting material, and can greatly increase the life of pump.
Description
Technical Field
The utility model relates to a centrifugal pump technical field, concretely relates to wear-resisting multistage centrifugal pump impeller.
Background
In order to reduce leakage and axial force, a small clearance seal is generally used at the mouth ring of the impeller and the back face of the impeller of the multistage centrifugal pump. After the pump is used for a period of time, the positions are greatly abraded, the gap is increased after abrasion, the axial force and the leakage amount are increased, the service life of the axial force balancing mechanism is shortened, and the pump efficiency is reduced.
Disclosure of Invention
In view of this, the utility model aims at providing a wear-resisting multistage centrifugal pump impeller.
In order to achieve the above purpose, the utility model provides a following technical scheme:
The utility model relates to a wear-resisting multistage centrifugal pump impeller, including impeller body, both ends are equipped with the choma installation department and the stator sealing ring installation department that are used for installing choma and stator sealing ring respectively around impeller body, have the wear-resisting material layer along spraying plating on the surface of choma installation department and stator sealing ring installation department.
Furthermore, the wear-resistant substance layer is sprayed chromium oxide, and the thickness of the wear-resistant substance layer is 0.2mm to 1 mm.
Furthermore, the wear-resistant material layer is a welding and spraying nickel-based alloy, and the thickness of the wear-resistant material layer is 0.5mm to 1.5 mm.
The beneficial effects of the utility model reside in that: the utility model discloses a set up the wearing substance layer on impeller body, make the impeller more wear-resisting to make its original efficiency who keeps the pump for a long time, the part adds wear-resisting material and compares the cost reduction with whole change wear-resisting material, and can greatly increase the life of pump.
Drawings
In order to make the purpose, technical scheme and beneficial effect of the utility model clearer, the utility model provides a following figure explains:
Fig. 1 is the structural schematic diagram of the wear-resistant multistage centrifugal pump impeller of the utility model.
In the figure, 1 is an impeller body, 2 is a mouth ring mounting part, and 3 is a guide vane seal ring mounting part.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
As shown in fig. 1, the utility model relates to a wear-resisting multistage centrifugal pump impeller, including impeller body 1, both ends are equipped with respectively and are used for installing the choma ring installation department 2 and the stator sealing ring installation department 3 of choma ring and stator sealing ring around impeller body 1, have the wearing substance layer along spraying plating on the surface of choma ring installation department 2 and stator sealing ring installation department 3. If not spraying coating wearing material layer, during operation, the installation department just can appear great wearing and tearing because hardness is lower to cause unfavorable consequence, behind the spraying coating wearing material layer, wear-resisting effect is very obvious, thereby reduces equipment maintenance, use cost.
In the embodiment, the wear-resistant material layer is sprayed chromium oxide, the thickness of the wear-resistant material layer is 0.2mm to 1mm, and the wear-resistant hardness of the wear-resistant material layer can reach 70 HRC.
in other embodiments, the wear-resistant material layer is a welding-sprayed nickel-based alloy with a thickness of 0.5mm to 1.5mm and a wear-resistant hardness of up to 60 HRC.
The utility model discloses a set up the wearing substance layer on impeller body, make the impeller more wear-resisting to make its original efficiency who keeps the pump for a long time, the part adds wear-resisting material and compares the cost reduction with whole change wear-resisting material, and can greatly increase the life of pump. And the cost of spraying the wear-resistant material layer is greatly lower than the purchase cost and the maintenance cost of the pump, so that the resources are saved.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
