Claims (10)
1. A shaft seal assembly, comprising:
a graham comprising a first surface and a second surface, wherein the first surface and the second surface have different directions of extension, and the first surface comprises a first groove;
a plurality of clamps removably disposed on the glans, wherein each clamp has a first aperture and a second aperture;
a plurality of first fixing pieces, wherein each first fixing piece passes through the first hole of each clamping piece and is partially inserted into the first groove to allow each clamping piece to slide in the first groove; and
and each second fixing piece passes through the second hole of each clamping piece and contacts the second surface so as to fix the clamping pieces on the second surface.
2. The shaft seal apparatus of claim 1 wherein said first groove comprises a continuous groove aligned along an outer edge of said first surface.
3. The shaft seal apparatus of claim 1 wherein said first groove comprises a plurality of discontinuous grooves which are not connected to one another and are aligned along the outer edge of said first surface.
4. The shaft seal apparatus of claim 1 wherein said second surface includes a second groove aligned along an outer edge of said second surface and permitting insertion of said plurality of second securement members.
5. The shaft seal apparatus of claim 1 wherein said gland includes an extension and said extension partially covers said clamp and exposes said first securing member.
6. The shaft seal apparatus of claim 1 wherein the position of said plurality of clamps is slidably adjusted by said plurality of first fixings and fixed by said plurality of second fixings.
7. A shaft seal assembly, comprising:
the grid comprises a first surface and a second surface, the first surface and the second surface have different extending directions, and the first surface comprises a groove for receiving a clamping piece, wherein a first hole of the clamping piece allows a first fixing piece to pass through and be inserted into the groove so that the clamping piece can slide in the groove through the first fixing piece, and a second hole of the clamping piece allows a second fixing piece to pass through and contact with the second surface so that the clamping piece is fixed on the grid.
8. The shaft seal apparatus of claim 7 wherein said groove comprises a continuous groove or a plurality of discontinuous grooves arranged along the outer edge of said first surface.
9. A method of installing a shaft seal assembly in a rotary machine, comprising:
sleeving a Glan on a rotating shaft of the rotating machine, wherein the Glan is provided with a first surface and a second surface, and the first surface is provided with a first groove;
placing a clamping piece on the first surface and the second surface of the gram, and enabling a first hole and a second hole of the clamping piece to correspond to the first surface and the second surface respectively;
inserting a first fixing member through the first hole and partially into the first groove so that the clamping member can slide in the first groove through the first fixing member to adjust the position of the clamping member; and
and a second fixing piece is arranged to penetrate through the second hole and is in contact with the second surface, so that the clamping piece is fixed on the second surface through the second fixing piece.
10. The method of claim 9 further including passing a third securing member through the opening of the clamp member to secure the shaft seal apparatus to the rotary machine.
