Abstract
The utility model provides a protective device for a pump shaft of a vertical filter wide flow. The protective device comprises a pump body, a shaft and an impeller. The protective device is characterized in that a protective shaft sleeve is sleeved on the shaft at the position close to the end of the impeller. When the vertical filter wide flow works in water which is shallow in depth for long time, slurry is sprayed out from a feeding port in a guard plate reversely and abrades the pump shaft continuously, resulting in fatigue failure of the shaft pump in advance. The protective device for the pump shaft of the vertical filter wide flow is used for preventing fatigue failure of the shaft pump. The protective shaft sleeve can effectively protect the shaft from abrasion and prolong the service life of the pump shaft, when the protective shaft sleeve is worn out, a user can change the protective shaft sleeve, and thus the production cost of the user is reduced.
Description
Technical field
The utility model relates to a kind of slag slurry pump under liquid, refers in particular on the slag slurry pump under liquid protective gear to axle.
Background technique
At present, conventional slag slurry pump under liquid pump head part-structure mainly is made up of backplate, impeller, the pump housing etc., and conventional slag slurry pump under liquid all is that slurry passes through filter screen, from backplate top and the two-way charging of suction port.According to designing requirement, the product of different model has the liquid level degree of depth of a pump operation the best.In the pump practice, often fluctuation up and down of the liquid level degree of depth in the time of may causing pump operation owing to different reasons, when the liquid level degree of depth shoaled, pump was become from the unidirectional charging of suction port by original two-way charging.After the liquid level degree of depth further shoals, slurry may go in the reverse ejection of intake port above backplate, if pump moves under this condition for a long time, and the axle on the continuous abrasion of the slurry meeting impeller that gushes out, cause the fracture of axle, influence the normal working life of pump.
Summary of the invention
In view of the above, purpose of the present invention is exactly the deficiency that will overcome in the former technology, and a kind of axle protective gear of novel practical type is provided, and makes pump when above-mentioned operating mode is moved, and can prolong the physical life of pump shaft greatly.
The technical solution of the utility model is achieved in that
A kind of protective gear of slag slurry pump under liquid pump shaft is provided, comprises the pump housing, axle and impeller, it is characterized in that: be with the protection axle sleeve at the axle near impeller end.
Advantage of the present utility model is: slag slurry pump under liquid axle sleeve protective gear is exactly for preventing that pump is for a long time when the superficial liquid level degree of depth is moved; the intake port of slurry above backplate oppositely ejection goes; denude pump shaft continuously, make axle cause fatigue fracture in advance because of wearing and tearing.This protection axle sleeve can effectively be protected the wearing and tearing of axle, prolongs the physical life of pump shaft greatly, and the wearing and tearing back only needs with changing axle sleeve, and user's cost of production also can reduce.
Description of drawings
Accompanying drawing is the utility model structural representation.
Specific embodiments
Below in conjunction with the description of drawings embodiments of the invention; But be not limited to present embodiment: be a kind of protective gear of slag slurry pump under liquid pump shaft shown in the figure, comprise the pump housing 1, axle 2 and impeller 3, be with abrasion-proof corrosion-proof protection axle sleeve 4 at the axle 2 near impeller 3 ends.
This slag slurry pump under liquid is as broad as long on produce assembling with conventional slag slurry pump under liquid, and is the same substantially, just earlier axle sleeve 4 embedded before impeller 3 is installed in spools 2 just, and the wearing and tearing that this structure can effectively be protected spool prolong the physical life of pump shaft greatly.
Though above shown detailed embodiment of the present invention, those skilled in the art is under prerequisite of the present invention, can carry out the part modifications and changes; The content of mentioning in description above and the accompanying drawing is the illustration of property as an illustration only, and is not limitation of the present invention, has the protective gear of a kind of slag slurry pump under liquid pump shaft of above-mentioned technical characteristics, all falls into this patent protection domain.
