Graphite packing a sealing a akyu gaw, bungli galaw ai masa amyu myu a majaw hkra machyi ai, madung gaw:
• Medium Pressure: High{0} myit n-gun n-gun n-gun (ga shadawn, 10 MPa hta jan ai) hta, n-gun n-gun hte n-gun shayawm ai atsam hpe rap ra hkra galaw na matu, multi{4}}layer composite packing structure (ga shadawn, graphite hte PTFE a galai shai ai lam ni) ra ai.
• Linear Speed: Roting shaft a linear speed gaw 10 m/s jan ai shaloi, packing a thermal conductivity hpe grau kaja hkra galaw ra ai (ga shadawn, katsi ai hpe n-gun jat wa hkra magri powder hpe jat bang nna) hpe grau kaja hkra galaw ra ai.
• Nbung laru n-gun: npu na nbung katsi ai shara (<-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: Dai ladat gaw n-gun ja ai oxidizing ntsin (ga shadawn, sulfuric acid hpe fuming galaw ai) rai yang, graphite gaw anti{2}}oxidation tsi lajang ai (ga shadawn, magri ntsin (sh) n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun) hpe lata ra ai.
Kaja wa jai lang ai lam hte seng ai lam ni hpe galaw ai lam ni
Graphite packing hpe sau, n-gun, sanghpaw li galaw ai lam, jak rung jak galaw ai lam ni hta grai lang ma ai. Typical application ni hta:
• Valve seals: tsaw ai- aten ladaw hta lang ai, tsaw ai{1}} myit n-gun n-gun n-gun n-gun n-gun (sh) n-gun n-rawng ai hka hpe hkang ai n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun (sh) rubber packings ni hpe galai shai ai;
• Pumps: centrifugal hte reciprocating pump ni hta shaft seal packing hku nna lang ai, grau nna acidic hte alkaline ntsin ni hpe htawn tsun na matu htuk manu ai;
• Agitators hte reactor ni: Tsaw ai wa{0}}}}}speed agitator shaft seals ni hta, hpawng de ai stuffing box design gaw, n-gun ja ai sealing hte leakage hpe hkang lu ai.
Ya aten na hpaji masa hpe gram lajang ai lam gaw, nanomaterial galai shai ai lam hku nna, bungli galaw ai lam hte kam hpa mai ai lam hpe grau kaja hkra galaw na matu (ga shadawn, n-gun shayawm ai lam hpe shayawm na matu molybdenum disulfide hpe jat bang ai zawn), npawt nhpang ningnan (ga shadawn, n-gun ja ai hku galai shai wa lu na matu corrugated packing rings zawn re ai), hte hpaji rawng ai hku yu reng ai lam (ga shadawn, n-gun n-gun n-gun n-gun/n-gun shayawm ai lam ni a matu, garan ginhka ai masa hte seng nna, tengman ai{0}} aten tengman ai ningmu ni a matu, n-gun jaw ai lam ni zawn re ai) hpe madung tawn ai.
Graphite packing gaw, shi a self-lu n-gun jaw ai majaw, tsaw ai{1}} aten kadun laman hpe ninghkap lu ai atsam, hte chemical stability ni a majaw, hpaga lam hte seng ai sealing field hta n mai malap ai arung arai langai mi tai wa sai. Shi a bungli galaw ai npawt tara gaw, arung arai galai shai ai lam hte lapran na n-gun atsam lapran na n-gun rawng ai rap ra lam hku nna, sealing hpe lu la na matu madung rai nga ai. Teng sha galaw ai lam gaw, bungli galaw ai parameter ni hpe shingdaw ai lam hte structural design a myit sawn sumru ai lam hta madung nga ai. Hpaji masa hte engineering hpaji masa ni rawt jat wa ai hte maren, graphite fillers ni a jai lang ai lamu ga jarit ni gaw matut nna jat wa na rai nna, madang tsaw ai hte yak hkak ai bungli masa ni a npu hta sealing ra kadawn ai lam ni a matu grau kaja ai hparan ladat ni hpe jaw ya na re.
