The High Strength Carbon Graphite Seal Rings For Aircraft Engines
ZC carbon manufactures and sells kinds ofresin impregnated high
pressure mechanical carbon graphite seal rings,which widely use in
petrochemical industry, mechanical engineering, metallurgy,
aerospace, aviation as well as marine technology.
Aircraft gearboxes reduce the rotational speed of the engine's main
shaft from up to 26,000 rpm to 3,400 rpm, so the shaft can drive
system components such as hydraulic pumps, generators, and
air-conditioning compressors. Seal the oil in the gearbox to
prevent it from leaking from the shaft into and out of the gearbox.
Most aircraft gearboxes use end face seals. Face seals typically
contain a carbon-graphite seal retaining ring and a silicon carbide
or tungsten carbide rotating ring. The dynamic end-faced rings are
flattened and fastened together by springs or magnets, so even in
the case of high-speed lower rings being turned away from each
other, liquid cannot flow between the ring surfaces.
You can benefit from these advantages:
1. Resin impregnated material would be good porosity & high
compressive strength
2. Its low cost but high quality compared raw graphite
3. High quality such as excellent self-lubricating, chemical
resistance and
stable performance in a long service life
4. Customized is provided according to your drawings or sample
5. ZC carbon technology meets your special dimensional needs
