Carbon Graphite Ring
The purpose of any seal device is to seal gases or liquids in the closed windows. The moving parts (shaft of piston rod) can protrude from the closed windows through seal devices so as to connect with the prime movers. Carbon graphite ring seals can be made into non-contact structure, that is leaving a small gap bhttpeen the fixed and moving parts, or the contact structure with the fixed and moving parts contacting each other. Contact seal devices need lubricants to reduce the friction and wear on the sliding contact surface. When the liquid medium itself has the lubricant capability, it can be used as the lubricant of the contact devices. If the working medium does not have that capability, and it does not allow the use of other lubricants, the contact seal without lubricants while operating should be adopted. When the sliding rate is low, and the working temperature and pressure are not high, soft seal filler which contains graphite can be used. We can also use the seal bowl made of leather, steel paper and fluorplastic or graphite ring made of strengthened plastics. The main ingredient of carbon graphite ring is graphite. Carbon graphite ring seals can be pressed into form by adding the stainless steel bushing. They can endure high temperatures, corrosion, and they are anti-aging, supple and springy. Carbon graphite ring seals possess excellent anti-corrosion capability, self-lubricant capability, a high conductivity coefficient, a small coefficient of expansion and a low friction coefficient. Therefore, they are the ideal vice materials for friction in the mechanic seal, suitable for a variety of mechanic seal devices. With the operating parameters of devices rising, hard graphite ring made of carbon graphite wear-resistant materials is immensely used nowadays to ensure the device to work reliably without lubricants, in graphite ring seals for printing and dyeing mechanics and in the high temperature, high heat and corrosive media. Graphite ring seals have already been widely used.
