Graphite packing sealing effectiveness hi operating parameter hrang hrangin a nghawng a, a bik takin:
• Medium Pressure: High-pressure environment (eg, 10 MPa aia tam) chuan sealing force leh deformation capacity balance nan multi-layer composite structure (eg, graphite leh PTFE layer inthlak danglam) a mamawh a.
• Linear Speed: Rotating shaft linear speed 10 m/s aia tam a nih chuan packing-a thermal conductivity chu a tha thei ang bera siam a ngai a (eg, heat dissipation tihpun nan copper powder dahin) localized overheating leh carbonization failure a awm loh nan.
• Temperature range: temperature hniam takah (temperature 1000 vel) .<-20°C), graphite may become more brittle, requiring flexibility treatment or composite with other materials (e.g., asbestos matrix) to improve its toughness.
• Medium Compatibility: Medium chu liquid (eg, fuming sulphuric acid) a oxidizing chak tak a nih chuan, graphite anti-oxidation treatment nei (eg, metal salt emaw organic compound emaw nei impregnation) thlan tur a ni.
