In one embodiment, a packing seal is further provided.
Such arrangement provides the advantage of requiring only one single packing seal (5).
A packing box (10) is provided for housing a packing seal (48) between a rotating shaft (32) and the casing (18) of a pump.
The seal can not only dissolve the problem of uneven radial pressure of packing seal but also further improve the seal performance by regulating radial seal pressure or clearance.
The packing seal comprises a first segment ring (1) which has at least two sealing segments (3) with locking segments (4) positioned between them in alternating order.
The sealing element may be a cup packer.
The apparatus includes an expandable packer assembly (60) and a sealing element (44) positioned in the treatment assembly (25) above the packer assembly (60).
In particular aspects, the packer device has a swellable elastomeric packer element.
A packer system including a packer and a setting mechanism.
The present invention features an apparatus comprising a packer means and a packer pressure sensing means.
A gland packing comprising a gland packing base material having its surface provided with a crystallized coating of orientated solid lubricant.
This gland packing can be produced by the above process.
Disclosed is a mechanical seal which can be suitably attached as a replacement for gland packing.
A gland packing (7) is placed between the top surface (51) and the bottom surface (61).
A gland packing formed from a material comprising an expansion graphite tape which is wound so as to be stacked in a spiral fashion.
It is proposed to use an insertion seal having radially opposite sealing surfaces of an outer seal (23) and an inner seal (24).
The valve portion includes an hourglass seal and a cross slit seal.
Either the stationary element (1) of or the rotating follower element (2) may hold packing (10) in a radial packing groove (9), as a sealing medium.
In an embodiment of the invention, the first seal is fastened by means of a second seal.
glazing material of a side scuttle
The first seal (10) is a mechanical seal positioned between the high pressure area and the chamber and the second seal (20) is a lip seal.
The sealing surfaces are fitted with at least one elastomeric seal.
Also, a lubricating bush is previously connected between the guide bar and a moving bush, and the rail hinge unit and the slide guide may be simultaneously molded by die casting or injection molding.
The seal (4) is made of an elastically deformable sealing material.
A cannula seal is presented.
Because of the firm engagement between the packing element and the printing needle, the packing element of this invention functions good when in use.
The packer assembly has at least one mechanically-set packer with at least one alternate flow channel.
The remote seal assembly also comprises a remote seal flange, a communication system and a capillary tube.
A communication port (74) is positioned between the sealing element (44) and the packer assembly (60).
This results that the opening is sealed by an insulation gasket (7) and the sheet-like gasket (16) or by the insulation gasket, the sheet-like gasket (16), and an inner gasket (10).
