Abstract
The utility model relates to a cooling type mechanical sealing device for a fluoroplastic pump. The cooling type mechanical sealing device comprises a spring seat, a stationary ring, a movable ring and a framework oil seal. A plurality of spring grooves are formed in the spring seat in an annular shape. A spring is arranged in each spring groove. One end of the movable ring abuts against the spring seat. The other end of the movable ring is tightly attached to the end face of the stationary ring and is movably connected with the stationary ring in a sealing mode. The framework oil seal is arranged on the outer end face of the spring seat in a mating and sleeved mode. Through the arrangement, a traditional bellows sealing mode is modified to be a mechanical sealing mode between the stationary ring and the movable ring, so that the overall tightness is improved greatly, and the problem, that pressure resistance and temperature resistance are low, existing in the bellows sealing mode is solved. The cooling type mechanical sealing device for the fluoroplastic pump has the advantages of being simple in structure, reasonable in design, compact in connection between all components, outstanding in sealing performance, convenient to wash and cool, long in overall service life, and outstanding in working performance.
Description
Technical field
The utility model relates to a kind of seal arrangement, relates in particular to a kind of fluoroplastic pump cooling type mechanical seal device.
Background technique
Plastic pump major part on the market all is to adopt bellows as the main body of seal arrangement at present, but there is withstand voltage low, defective such as heatproof is low and sealability is unreliable in it, also not to the cooling way of seal arrangement, influence the working life of seal arrangement, reduced the working stability of plastic pump.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, a kind of simple in structure, good seal performance is provided and has fluoroplastic pump cooling type mechanical seal device to the seal arrangement refrigerating function.
For achieving the above object, the utility model adopts a kind of fluoroplastic pump cooling type mechanical seal device, comprise spring seat, stationary ring, rotating ring and outside framework oil seal, annular is provided with a plurality of spring grooves on the spring seat, be provided with spring in each spring groove, the setting that offsets of an end of described rotating ring and spring seat, the other end of rotating ring is close to the end face setting of stationary ring, and constitute motive sealing with stationary ring and be connected the adaptive exterior edge face that is set in spring seat of outside framework oil seal.
Traditional sylphon seal is improved to mechanical seal between stationary ring and the rotating ring, improves whole sealing greatly, and withstand voltage low, the problem such as heatproof is low that have solved that sylphon seal occurs.
The utility model further arranges again, the fluoroplastic pump also comprises a pedestal with the cooling type mechanical seal device, the sectional shape of described pedestal is L shaped, the adaptive exterior edge face that is set in outside framework oil seal of pedestal, the L shaped long side ring shape of pedestal is provided with a flushing hole, the corresponding stationary ring of described flushing hole and rotating ring setting.
The position that the alignment stationary ring is connected with rotating ring on the pedestal is provided with flushing hole, in device work, can wash stationary ring and rotating ring by this flushing hole, to reach instant cooling, has improved the working life of seal arrangement, has guaranteed service behaviour.
The utility model further arranges again, and the sectional shape of stationary ring is convex, and the convex portion both sides of convex are provided with pad, and spring seat cylindrical and outside framework oil seal assembly form Seal cage.
Stationary ring is set to convex, has made things convenient for the installation of stationary ring, has guaranteed the installation soundness of stationary ring, and pad has avoided stationary ring wearing and tearing, life-saving to occur in the process of work.
In sum, the beneficial effects of the utility model are: the fluoroplastic pump is that single end face is adorned the balance type unit loading type outward with the employing of cooling type mechanical seal device, spring deviates from medium, adds the cooling water setting, and is simple in structure, reasonable in design, connect compact between each parts, constitute reliable motive sealing between stationary ring and the rotating ring and is connected, sealability is outstanding, and convenient flushing to seal arrangement is cooled off, whole service life is long, and service behaviour is outstanding.
