Abstract
The utility model relates to an impeller spindle nose sealing structure of an immersible pump for a corrosion occasion, which comprises a pump shaft and an impeller. The utility model is characterized in that the impeller is sheathed at the front part of the pump shaft; the top end of the pump shaft is provided with a convex column extending out of the impeller; the side surface of the convex column is provided with screw threads and an impeller nut; a thread hole which sinks inwards is arranged in the impeller nut and is matched with the convex column of impeller and the screw threads of the impeller; a sealing ring is arranged between the impeller nut and the impeller, and the end surface of the external side of the impeller nut is connected with the extending surface of middle part surface of the impeller. The utility model has the advantage that the utility model can prevent the pump shaft from being corroded by corrosive liquid.
Description
Technical field
The utility model relates to a kind of sealing configuration, particularly a kind of submersible pump impeller end spindle nose sealing configuration that is used to corrode occasion.
Background technique
Existing plain edition proof submersible sand discharging pump is when installing impeller, it is the end face that impeller directly is enclosed within pump shaft, use impeller pressing plate, screw-driving then, therefore when the plain edition proof submersible sand discharging pump is used to contain corrosive liquids, the corrosive liquids of being pumped by proof submersible sand discharging pump that contains is easy to enter pump shaft from the gap between impeller and the impeller pressing plate, long-term use will be easy to generate the situation that pump shaft is corroded, and not contain mordant occasion so the plain edition proof submersible sand discharging pump can only be applicable to the medium of pumping.
Summary of the invention
The purpose of this utility model be solve plain edition proof submersible sand discharging pump in the prior art pump contain corrosive liquids the time pump shaft existing problem that is corroded takes place easily, provide a kind of pump shaft that can prevent to be contained the submersible pump impeller end spindle nose sealing configuration of corrosive liquids corrosion.The utility model is designed for the submersible pump impeller end spindle nose sealing configuration of corrosion occasion, comprise pump shaft, impeller, it is characterized in that: impeller set is in the front portion of pump shaft, the protruding post that stretches out in impeller is arranged on the top of pump shaft, on the side surface of protruding post, screw thread is arranged, an impeller nut is arranged, the tapped hole that sinks on impeller nut, offering, the interior heavy tapped hole and the protruding post and the threads engaged thereof of impeller have seal ring between impeller nut and impeller.The outside end face of impeller nut is stretched face with the edge of impeller middle part surface and is connected mutually.The utility model has the advantages that and to prevent that pump shaft from being contained the corrosive liquids corrosion.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise pump shaft 1, impeller 2 among the figure, it is characterized in that: impeller 2 is enclosed within the front portion of pump shaft 1, the protruding post 3 that stretches out in impeller 2 is arranged on the top of pump shaft 1, screw thread 4 is arranged on the side surface of protruding post 3, one impeller nut 5 is arranged, the tapped hole 6 that sinks in offering on impeller nut 5, interior heavy tapped hole 6 matches with the protruding post 3 and the screw thread 4 thereof of impeller 2, between impeller nut 5 and impeller 2 seal ring 7 is arranged.The outside end face of impeller nut 5 is stretched face with the edge of impeller 2 middle part surfaces and is connected mutually.
Sealing has just been realized in impeller 2 end pump shafts 1 head position like this, and containing mordant medium can't enter pump shaft 1 head by impeller 2 installation places, protect pump shaft 1 not weather.
Claims (2)
1, is used to corrode the submersible pump impeller end spindle nose sealing configuration of occasion, comprise pump shaft, impeller, it is characterized in that: impeller set is in the front portion of pump shaft, the protruding post that stretches out in impeller is arranged on the top of pump shaft, on the side surface of protruding post, screw thread is arranged, an impeller nut is arranged, the tapped hole that sinks on impeller nut, offering, the interior heavy tapped hole and the protruding post and the threads engaged thereof of impeller have seal ring between impeller nut and impeller.
2, by the described submersible pump impeller end spindle nose sealing configuration that is used to corrode occasion of claim 1, it is characterized in that: the outside end face of impeller nut is stretched face with the edge of impeller middle part surface and is connected mutually.
