1. Fɛn dilannenw (Product Core).

Graphite pake gland ye degun-daga kɛrɛnkɛrɛnnen ye min dabɔra kɛrɛnkɛrɛnnenya la graphite pake bɛnni kama (graphite packing flexible, graphite pake barikama, a ɲɔgɔnnaw). A ka baara koloma ye ka bololanɛgɛw sirili fanga caman sɛmɛntiya ka kɛ degun kelen ye, ka grafite pakew digidigi walasa ka yɔrɔ fa minɛnw lamaga-lamagali yɔrɔw (misali la, jirisunw) ni fɛnw falen-falen kɛsu cɛ-o cogo la ka kɛ sababu ye ka dasiri, min ka dɔgɔ-friction sealing interface. O ɲɔgɔndan in bɛ kunnafonidilanw (jiw, gaziw, watara) bɔli bali kosɛbɛ k’a sɔrɔ a bɛ yɔrɔw jiginni dɔɔnin kɛ aksidan/radiyali la.

A nafa jɔnjɔnw bɛ ye ninnu na:

Dimi minnu bɛ sɔrɔ laadala pakew sigicogo la, olu ɲɛnabɔli la, i n’a fɔ pakew degunbaliya ni sigilan dɛsɛ min bɛ sɔrɔ degun lafiyali fɛ;

Bɛnni ni grafite pake suguya caman n’a fɛn ɲɛfɔlenw ye (misali la, grafite pake saniyalen, Inconel-grafite pake barikama), min bɛnnen don izini minɛn suguya caman ɲɔgɔndanw ma (pɔnpew, valvew, reactors)

Grafite pakew baara waati janya ni doni fɔlɔ sabatili ye, min bɛ to senna, ani ka musakaw dɔgɔya minnu bɛ tali kɛ fɛnw caman cili la tuma caman na.

(1) ye. Durable & Corrosion-Materiel Resistant Sugandili

Ka izini nɛgɛ kɔrɔw ta minnu fanga ka bon ni masinw ye ani minnu bɛ se ka sɔgɔsɔgɔ:

304/316 nɛgɛ min tɛ sɔgɔ : A bɛnnen don fɛn caman ma minnu bɛ fɛnw tiɲɛ (misali la, tuluw, asidi barikamaw);

Hastelloy C-276 : A bɛnnen don fɛnw ma minnu bɛ fɛnw tiɲɛ kosɛbɛ (misali la, asidi sulfuriki, gazi kulori);

Karɔbɔli nɛgɛ min datugulen don: A musaka ka dɔgɔ, a bɛnnen don sigidaw ma minnu tɛ -nɔgɔ.

O fɛnw bɛ se ka oksidan, kemikɛli sɔgɔli, ani funteni jiginni kɛlɛ, o bɛ kɛ sababu ye ka baara kɛ waati jan kɔnɔ min bɛ se ka da a kan sigida gɛlɛnw na.

(2) ye. Structural Design ka ɲɛsin sigicogo ɲuman ma

Jateminɛba fila minnu bɛ kɛ:

Integral suguya: A bɛnnen don -janya fɛnɲɛnamafagalanw/valve fitininw ma; a sigili ka nɔgɔn, ni bɔgɔbɔgɔli farati ka dɔgɔn;

Tilalen suguya: A bɛnnen don minɛnba-janya ma walima yɔrɔ la -yɔrɔ ladonni ma; kun t’a la ka jirisunba tigɛ, o bɛ dɔ bɔ jɔli waati la ni 40% ni kɔ ye;

Precision-machined inner bores: Surface roughness Ra A ka dɔgɔn walima a bɛ bɛn 1,6 μm ma, a bɛ bɛn kosɛbɛ ni jirisunw/valve stems ye walasa ka "kɛrɛfɛ bɔgɔbɔli" bali min bɛ sɔrɔ yɔrɔw fɛ minnu ka ca kojugu

Bolo dingɛw tilatilali cogo kelen na: Ka a lajɛ ni fanga min bɛ kɛ ka kɔn-gɛlɛya ɲɛ, o bɛ bɛn, ka sigida degunba walima degun dɔgɔyali bali grafite pakew la.

(3) ye. Baarakɛcogo caman bɛ se ka ladamu

Grafite pakew baarakɛcogo bɛnbaliya walasa ka baarakɛcogo juguw muɲu:

Funteni hakɛ: -200℃~600℃(fiɲɛ/oksidan fiɲɛ); fo ka se degere 800 ma fiɲɛ na min tɛ baara kɛ ni a farala ɲɔgɔn kan ni pakew ye minnu bɛ funteni caman na;

Tansiyɔn hakɛ : A ka dɔgɔn walima a bɛ bɛn 40MPa ma (tansiyɔn jɔlen), min bɛnnen don tansiyɔnba-pɔnpew ni reactorw ma petoroli ni nukliyɛri fanga forow la

Fɛnɲɛnɛmafagalanw bɛnkan : A bɛ bɛn izini kunnafonidilan fanba ma, i n’a fɔ tuluw, fɛnɲɛnamafagalanw, asidi/alkali (pH 2-14), funteni caman, ani gazi minnu tɛ baara kɛ.

(4) ye. Ladonni nɔgɔya & Baara musaka dɔgɔman

Fanga min bɛ se ka ladilan ka kɔn-gɛlɛya ɲɛ : Bolo bɛ se ka siri kokura baarakɛtuma na walasa ka pakew sɛgɛnni musaka bɔ, o bɛ sigilan si janya siɲɛ 2-3 ni i ye a suma ni glande jɔlenw ye

Dilancogo nɔgɔman : a ka nɔgɔn 30% ka tɛmɛ nɛgɛdagaw kan minnu ka ɲɛfɔli kelen bɛ, o bɛ nɔgɔya don-yɔrɔ la ka baara kɛ ni a sigili ye;

Baarakɛminɛn kɛrɛnkɛrɛnnenw tɛ wajibiya: A bɔli ni a lajɛli bɛ se ka ban ni fɛn dɔ ye min bɛ kɛ tuma bɛɛ, o bɛ dɔ bɔ baarakɛlaw musakaw la.
