Customized Dry Gas Carbon Graphite Seal Rings In Pumping Machine
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.
When the moving ring of the fluid dynamic pressure groove
(2.5~10µm) is opened on the outer side of the end face,
the fluid dynamic pressure groove pumps the high-pressure isolation
gas on the outer diameter side (referred to as the upstream side)
between the sealing end faces. The film pressure gradually
increases from the diameter to the groove diameter, and the film
pressure gradually decreases from the groove diameter to the inner
diameter. The opening force generated by the increase of the end
face film pressure is greater than the closing force acting on the
sealing ring, between the friction pairs. A very thin film of air
(1~3µm) is formed to make the seal work in a non-contact
state. The formed gas film completely blocks the relatively low
pressure sealing medium leakage passage, achieving zero leakage or
zero escape of the sealing medium.
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
