Description
Technical field
The utility model belongs to pumping unit technical field, specifically relates to a kind of dual-gripper pump packaging sealing device.
Background technique
When pump operates, rotor coaxial rotates together, when rotor and axle matching loose, rotor can axial float, be arranged on wearing plate inside and outside rotor will with rotor end-face friction, frictional force is excessive will cause rubberizing layer on rotor to peel off or metallic rotator stuck phenomenon.
Summary of the invention
The utility model mainly solves the technical problem existing for above-mentioned prior art, a kind of dual-gripper pump packaging sealing device is provided, by arranging the identical inside and outside packaging sealing device of structure, and the shaft shoulder is set in the rotating shaft at interior packaging sealing device place, make rotor and interior packaging sealing device axial limiting; The rotating shaft at the outer packaging sealing device place that rotating shaft is installed arranges axial back-up ring, and axial back-up ring rotates together with rotating shaft and bearing, has set screw nut and the locking of anti-turning pad sheet, make outer packaging sealing device axial limiting in roller end; Inside and outside like this packaging sealing device can restrict rotor displacement in the axial direction very well, rotor would not because of pressure reduction axial float, avoid because of rotor end-face and wearing plate frictional force excessive and stuck.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of dual-gripper pump packaging sealing device, comprise rotating shaft, described rotating shaft arranges rotor, described rotor is arranged interior packaging sealing device and outer packaging sealing device, described interior packaging sealing device is identical with outer packaging sealing device structure, described interior packaging sealing device and outer packaging sealing device comprise rotating seat, described rotating seat arranges spring mounting seat, described spring mounting seat arranges spring, described spring is connected with spring washer, described spring washer is connected with stationary ring, described stationary ring is connected with rotating ring, described stationary ring and spring mounting seat arrange stationary seat, described stationary seat is arranged two O type circles, 2nd O type circle is set between described stationary seat and stationary ring, 3rd O type circle is set between described rotating seat and rotating ring, the rotating shaft at described outer packaging sealing device place also arranges axial back-up ring, described axial back-up ring arranges oil sealing.
As preferably, described rotating shaft arranges bearing, described bearing is arranged anti-rotation pad, described anti-rotation pad arranges set screw nut.
As preferably, described rotating shaft also arranges the shaft shoulder, the described shaft shoulder props up interior packaging sealing device, plays the effect to rotor and interior packaging sealing device axial limiting.
The beneficial effect that the utility model has: by arranging the identical inside and outside packaging sealing device of structure, and the shaft shoulder being set in the rotating shaft at interior packaging sealing device place, making rotor and interior packaging sealing device axial limiting; The rotating shaft at the outer packaging sealing device place that rotating shaft is installed arranges axial back-up ring, and axial back-up ring rotates together with rotating shaft and bearing, has set screw nut and the locking of anti-turning pad sheet, make outer packaging sealing device axial limiting in roller end; Inside and outside like this packaging sealing device can restrict rotor displacement in the axial direction very well, rotor would not because of pressure reduction axial float, avoid because of rotor end-face and wearing plate frictional force excessive and stuck.Therefore the utility model has the features such as structure is simple, reasonable in design.
Accompanying drawing explanation
