| ASBESTOS GLAND PACKING |
| To achieve zero leakage between a moving member and a
relatively stationary part, a wide range of seals and rings are
employed. However, the most common, last expensive and versatile in
nature is the Gland Packing. Gland Packing provides a dynamic seal for
or stem via a housing or gland which resilient or semi - resilient
material, thus providing a localised contact area which offers a
physical barrier to leakage. |
| PROPERTIES THE GLAND PACKING MUST POSSES. |
| * Good anti-friction properties |
| * Good chemical resistance to fluid contained |
| * Should not get effected by the temperature of
application. |
| * Should be reasonably compressible and have a
good resilience. |
| * Should retain the self lubricants. |
| * Should not effect the shaft. |
| * should not contaminate the fluid being
contained. |
| |
| Eastwell Asbestos Industries (Pvt) Ltd., manufacturers a
wide range of Gland Packings to suit a variety of applications. They are
both, of Dry as well as Lubricated type. |
| Gland Packings are not an exact science as its
performance depends upon many variables. The filling of a packing is an
art and results depend largely on manual skills. The 'Man with a Wrench'
therefore, can sometimes, be a dangerous person in your plant,
responsible for scored rods, excessive down time and wasted packings. |
| |
| Eastwell Asbestos Industries (Pvt) Ltd., take great case
at the construction stage of its gland packings which leads to a better
performance even under minor imperfections in the plant condition and
fitment, however, certain preparatory precautions, correct procedure of
fitment and correct selection of grade and size of the gland packing
would help in achieving the best results. |
| |
| CONDITION OF PLANT : To ensure long and trouble-free
sealing, check the following periodically : |
| * The clearance between shaft and neck-bush at the
bottom end of the stuffing box. The maximum normal clearance is 0.25 mm. |
| * Concentricity of shaft with stuffing box bore. |
| * Straightness of shaft (run-out)-- not to exceed
0.05 mm. Clock guage reading. |
| * Condition of shaft surface in packing area -- no
excessive grooves, scores or pitting. |
| * Pump bearings -- wear can induce shaft "whip"
which can be harmful to packings. |
| |
| PACKING THE GLAND |
| * Ensure that all the old packing is removed and
the stuffing box is clean and from foreign matter. |
| * Always re-pack with new packing. |
| * Choose packings recommended for the fluid to be
contained. |
| * Select correct size of packing to fit the
stuffing box dimensions. |
| * Wrap packing on the shaft and cut into rings of
correct size. |
| * Fit each packing individually by tamping of with
split sleeves. |
| * Stagger joints in consecutive packing rings. |
| * Fit gland follower and check that the shaft
rotates freely. |
| * Tighten gland nuts evenly with spanner unit the
packing "drags" when turning the shaft by hand. |
| |
| a) Valves - pressurise the stuffing box and if
necessary readjust the gland nuts evenly until a leak-free seal is
obtained. |
| b) Pumps - Slacken the gland nuts back and re-tighten to
finger tight, to such an extent that the shaft still rotates freely. |
