Description
STRUCTURE:

The wattled high-quality flexible graphite fibers reinforced by a cotton thread, impregnated politetraftoretileny (PTFE) on special thermo - chemical technology.



APPOINTMENT:

Consolidation of shaft of centrifugal and plunger pumps.



WORKING ENVIRONMENTS:

Various hot water, oil products, lubricant oil, thermal oil, organic solvents.



ADVANTAGES:

In usual wattled stuffings (on the basis of asbestine, linen, synthetic and other threads) there are possible ways of leaks between fibers. However stuffing under pressure of a cover of an omental chamber forms homogeneous weight of wattled graphite fiber and leaks do not happen. Thus, leakages are controlled at much smaller efforts of an inhaling that promotes increase in service life of stuffing.



Low coefficient of friction. At graphite extremely low coefficient of friction - about 0,05. This indicator is much lower, than at many fibers applied to production of stuffings. For comparison, coefficient of friction of asbestos - 0,5. Thanks to application of stuffing from pure graphite in omental consolidations the thermal emission sharply decreases and decrease in electricity consumption on pumps is possible. This stuffing is self-greased. To replace a worn-out layer of material the layer from just the same material, but not a layer, for example, of dry abrasive asbestos is bared. It considerably increases stuffing service life, and also reduces wear of shaft/plugs.



High heat conductivity. Graphite possesses considerably bigger heat conductivity (40 x 100 W / m*k), than materials of traditional stuffings (for example, at asbestos - 0,1 x 0,3 W / m*k) thanks to what in omental cameras of pumps warmly effectively dissipates - the number of leaks, necessary for carrying out of heat, is minimized.
