Abstract
The utility model provides a centrifugal thick liquid pump, pump shaft and impeller including interconnect, be equipped with wheel hub on the impeller, wheel hub's inside is equipped with the internal thread, the axle head of pump shaft be equipped with with the external screw thread that interior screw -thread fit screwed, the axle head of pump shaft stretches into wheel hub's inside is just passed through external screw thread and internal thread are mutually supported and are screwed, the shaft shoulder of pump shaft department still be equipped with with the fixed check bolt of pump shaft and impeller, this novel technical requirement that can reach centrifugal thick liquid pump, the very light screw in axle head of impeller during the assembly targets the back in place with check bolt locking, not only can the accurate positioning but also can lock the impeller, ensures that the impeller all is unlikely to to drop in work and when shutting down, without specialized tool during the dismantlement, after taking off the check bolt with the spanner, only need with the impeller along rectangular thread revolve to opposite spin can easily get lower vane, avoided the dress and the complex process that tears open, saved manpower and materials.
Description
Technical field
The utility model relates generally to liquor pump field, is specifically related to a kind of centrifugal slurry pump.
Background technique
At present, centrifugal slurry pump pump shaft and impeller Placement are all that flat key is connected, and this Placement needs hammering to assemble when mounted, needs removal tool special during dismounting; Particularly easily tied when slurries condense, be difficult to pull down.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of centrifugal slurry pump, can reach the technical requirements of centrifugal slurry pump, during assembling, impeller screws in axle head very easily, without special tool during dismounting, avoid the complex process of installation and dismantling, save manpower and materials.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of centrifugal slurry pump, comprise interconnective pump shaft and impeller, described impeller is provided with wheel hub, the inside of described wheel hub is provided with internal thread, the axle head of described pump shaft is provided with the outside thread screwed with described screw-internal thread fit, the inside and being cooperatively interacted by described outside thread and internal thread that the axle head of described pump shaft stretches into described wheel hub is screwed, and the shaft shoulder place of described pump shaft is also provided with described pump shaft and the fixing chek bolt of impeller.
The beneficial effects of the utility model are: this Placement can reach the technical requirements of centrifugal slurry pump, during assembling, impeller screws in axle head very easily, with chek bolt locking after putting in place, not only accurately can locating but also can impeller locking, having guaranteed that impeller was all unlikely to come off when working and shut down; Without special tool during dismounting, after taking off chek bolt with spanner, only impeller easily can need be taken off impeller along the opposite spin of square threaded form rotation direction, avoid the complex process of installation and dismantling, save manpower and materials.
On the basis of technique scheme, the utility model can also do following improvement.
Further, positioning hole is provided with near the end of the described wheel hub of the described pump shaft shaft shoulder, described chek bolt passes described positioning hole and described pump shaft and described impeller is fixed in the vertical shaft shoulder screwing in described pump shaft, and the shaft shoulder of described pump shaft withstands on the positioning hole of described wheel hub.
Adopt the beneficial effect of above-mentioned further scheme to be: chek bolt can lock pump shaft and impeller, installation and removal easily and fast.
Further, the surface of contact of described wheel hub and the described pump shaft shaft shoulder is plane.
Adopt the beneficial effect of above-mentioned further scheme to be: make pump shaft and impeller Percent of contact area high, combine closely, not easily get loose.
