Graphite Sealing Nplhaib: Technical Parameters thiab Performance
Apr 19, 2026| Qhov tseem ceeb ntawm lub cev tsis sib xws ntawm graphite sealing rings suav nrog qhov ntom ntawm 1.4–1.8 g / cm³ thiab cov tshuaj tiv thaiv kab mob muaj feem xyuam rau pH qhov tseem ceeb ntawm 0 txog 14. Lawv qhov siab tshaj plaws ua haujlwm kub yog los ntawm -200℃txog 800℃hauv non-oxidizing ib puag ncig, thiab los ntawm -20℃ib puag ncig oxidizing.
Qhov siab tshaj plaws kev khiav hauj lwm siab rau graphite tus kheej- sealing rings tuaj yeem ncav cuag 35 MPa (kwv yees li 250 kgf / cm²), thaum rau qee qhov siab - kev siv siab- xws li hauv li qub - nws tuaj yeem txuas mus txog 800 bar. Lawv qhov kev tso cai tawm tshaj tawm tuaj yeem ncav cuag 12 m / s.
Graphite tus kheej- sealing rings muaj ntau yam ntawm cov yam ntxwv tseem ceeb, nrog rau tus kheej zoo heev -lubricity, siab coefficient ntawm resilience, superior compressibility thiab elasticity, impermeability, corrosion kuj, tsis kam mus rau aging, ib tug ntev kev pab cuam lub neej, hnav tsis kam, thiab muaj peev xwm ua kom tau raws li qhov xav tau ntawm kev hnav.
