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
