Shaft Seal

Outside type mechanical seal device

The invention discloses an outside type mechanical seal device disposing the mechanical seal main body at the atmospheric side so as to stop leak of shaft seal of rotary shaft, comprising an annular stopper ring fixed on the rotary shaft by a setbolt, an annular flange bolted to the fixed side, plural protrusions formed integrally at positions confronting the stopper ring outer circumference in the flange at specified intervals to the outer circumference.

Spacers interposed between the inside of the protrusions and the outer circumference of the stopper ring, and cap bolts detachably driven into the stopper ring through the protrusions and spacers from outside the protrusions, wherein the axial center of rotary shaft of the stopper ring disposed on the rotary shaft is securely positioned in the radial direction and thrust direction, and the entire outside type mechanical seal composed of multiple parts is formed into one integral unit, thereby facilitating the assembling performance.

Mechanical seal devices have been hitherto classified in two types, that is, the inside type mechanical seal having the mechanical seal main body disposed at the fluid side such as liquid and gas, and the outside type mechanical seal having the mechanical seal main body disposed at the atmospheric side, and the inside type mechanical seal has been available in the integrated unit type, whereas the outside type mechanical seal device is not available in the integrated unit type at the present.

Accordingly, in the conventional outside type mechanical seal, it required an experienced skill in assembling the mechanical seal consisting of multiple parts including flange, seat ring, rotary ring, stopper ring, spring, O-ring and others, between the rotary shaft and the fixed side (for example, the stuffing box of the pump), and the assembling performance was poor.

It is hence a primary object of the invention to present an outside type mechanical seal device capable of securely positioning in the radial direction and thrust direction to the axial center of the rotary shaft of the stopper ring disposed on the rotary shaft, integrating the entire mechanical seal composed of multiple parts into one unit, and facilitating the assembling performance.

An outside type mechanical seal device capable of achieving more secure positioning in the radial direction and thrust direction to the axial center of the rotary shaft of the stopper ring disposed on the rotary shaft.

Since the stopper ring can be securely positioned thus in the radial direction and thrust direction, the entire mechanical seal device made of multiple parts can be integrated into a unit.

Therefore, when assembling the mechanical seal device, the integrated unit is assembled between the rotary shaft and the stuffing box of the pump as the fixed side as described below, and the assembling job may be facilitated, so that any particular skill is not needed in assembling.

That is, to assemble the mechanical seal device, to assemble the mechanical seal device, in the first place, the integrated unit of mechanical seal device is inserted into the rotary shaft, and the stuffing box of the pump casing is incorporated. In this state, using the flange bolt not shown from the atmospheric side AI, and using the grooves, the flange bolt is tightened into the screw hole (not shown) of the stuffing box side, and the integrated unit of the mechanical seal device is bolted to the stuffing box.

In short, according to claim of the invention, by the thickness of the plural spacers interposed between the inside of the protrusions and the outer circumference of the stopper ring, the stopper ring disposed on the rotary shaft is positioned in the radial direction to the axial center of the rotary shaft, and the cap bolt penetrates through the spacer to be screwed in the stopper ring, the stopper ring is positioned in the thrust direction (axial direction) to the rotary shaft.

In this way, since the stopper can be positioned securely in both radial direction and thrust direction, the entire mechanical seal composed of multiple parts can be integrated into a unit. Therefore, when assembling the mechanical seal, only the integrated unit may be incorporated between the rotary shaft and the fixed side, and the assembling job may be facilitated, thereby not requiring any particular skill.
