Description
Technical field
The utility model relates to pump technical field, be specifically related to pump shaft.
Background technique
In centrifugal pump, pump shaft is as the critical piece transmitting mechanical energy, be connected with motor by means of coupling, impeller is passed in the torque of motor, its effect is self-evident, centrifugal pump wearing and tearing are unavoidable problems, during centrifugal pump work, owing to there is friction between pump shaft and centrifugal pump inner stuffing, centrifugal pump is easily caused easily to leak, this not only lowers the working life of pump shaft, also there is certain potential safety hazard.In magnetic drive pump, pump shaft and axle sleeve rub and also can cause shorten and potential safety hazard the working life of pump shaft.Based on this, design a kind of novel pump shaft of centrifugal pump or necessary.
Summary of the invention
For the deficiency that prior art exists, the utility model object is to provide a kind of pump shaft, and structure is simple, and reasonable in design, wear resistant corrosion resistant, effectively improves the working life of pump shaft, be widely used.
To achieve these goals, the utility model realizes by the following technical solutions: pump shaft, comprise pump shaft, bottom and sprayfused coating, the local surfaces of pump shaft is provided with bottom, the outer surface of bottom is coated with sprayfused coating, sprayfused coating adopts special alloy or special cermacis material, and utilize the mode of supersonic speed or the spray of plasma heat that sprayfused coating is sprayed on axle surface, wear resistance is strong.
As preferably, described pump shaft is provided with at the bottom of contact machine, the outer surface of contact at the bottom of machine is provided with wear-resistant ceramic cover, and the middle wear resistance of pump shaft is good.
The beneficial effects of the utility model: reduce frictional force, add abrasion resistance, not only wear-resisting but also corrosion-resistant, effectively improve the working life of pump shaft, reduce the risk that pump is revealed, and improve pump working life, apply very extensive.
