The creation discloses an outside sort Mechanical Seals gadget disposing the mechanised seal principal plan in the atmospheric facet so concerning cease leak of shaft seal of rotary shaft, comprising an annular stopper ring repaired inside the rotary shaft with a setbolt, an annular flange bolted in the direction of repaired side, plural protrusions established integrally at positions confronting the stopper ring external circumference while in the flange at specified intervals in the direction of external circumference.

Spacers interposed in between the within in the protrusions as well as the external circumference in the stopper ring, and hat bolts detachably driven to the stopper ring by method of the protrusions and spacers from outside the protrusions, wherein the axial center of rotary shaft in the stopper ring disposed inside the rotary shaft is securely positioned while in the radial path and thrust direction, as well as the whole outside sort Mechanical Seals composed of many components is established into one integral unit, thus facilitating the assembling performance.

Mechanical Seals equipment are actually hitherto classified in two types, that is, the within sort mechanised seal owning the mechanised seal principal plan disposed in the fluid facet for example fluid and gas, as well as the outside sort mechanised seal owning the mechanised seal principal plan disposed in the atmospheric side, as well as the within sort mechanised seal have been readily available while in the integrated gadget type, whereas the outside sort mechanised seal gadget is not readily available while in the integrated gadget sort in the present.

Accordingly, while in the conventional outside sort mechanical seal, it required an experienced technique in assembling the Mechanical Seals consisting of many components such as flange, seat ring, rotary ring, stopper ring, spring, O-ring and others, in between the rotary shaft as well as the repaired facet (for example, the stuffing box in the pump), as well as the assembling common performance was poor.

It is therefore a principal item in the creation to current an outside sort mechanical seal gadget capable of securely positioning while in the radial path and thrust path in the direction of axial center in the rotary shaft in the stopper ring disposed inside the rotary shaft, integrating the whole Mechanical Seals composed of many components into one unit, and facilitating the assembling performance.

An outside sort mechanical seal gadget capable of achieving an awesome offer more safe positioning while in the radial path and thrust path in the direction of axial center in the rotary shaft in the stopper ring disposed inside the rotary shaft.

Since the stopper ring may be securely positioned so while in the radial path and thrust direction, the whole mechanical seal gadget developed of many components may be integrated in to a unit.

Therefore, when assembling the mechanical seal device, the integrated gadget is assembled in between the rotary shaft as well as the stuffing box in the pump since the repaired facet as described below, as well as the assembling duty may maybe be facilitated, to make certain that any particular technique is not required in assembling.

That is, to assemble the mechanical seal device, to assemble the mechanical seal device, while in the original place, the integrated gadget of mechanical seal gadget is inserted to the rotary shaft, as well as the stuffing box in the pump casing is incorporated. on this state, utilizing the flange bolt not revealed while in the atmospheric facet AI, and utilizing the grooves, the flange bolt is tightened to the screw hole (not shown) in the stuffing box side, as well as the integrated gadget in the mechanical seal gadget is bolted in the direction of stuffing box.
