ʻO ka lipine hoʻopaʻa kiʻi kipi graphite
1. Nānā Huahana
Mea Hana: graphite hikiwawe ma'ema'e
Hoʻolālā: ʻO ke ʻano ʻahuʻula kū hoʻokahi ma ka ʻili
Manaʻo Hoʻolālā: No ka ʻāpana o ka ʻili o nā kiwi ʻoihana, nā pāpaʻi, nā mea hoʻololi
ʻO ka waiwai kumu: ʻO ka hana hoʻopaʻa sila maikaʻi loa, ke ola lōʻihi o ka lawelawe ʻana, maʻalahi ka hoʻokomo ʻana; lubricating pono'ī, ka wela kiʻekiʻe/ʻeleʻele; ka hoʻololi kūpono no nā packing maʻamau (asbestos, PTFE) i nā noi koi
2. Nā mea nui a me nā pono
ʻO ka hana hoʻopaʻa ʻana: Hoʻopili maikaʻi ʻia ka graphite maʻalahi; mālama i ka sila maikaʻi ma lalo o ke kaomi ʻana a i ʻole ka ʻaʻahu liʻiliʻi o ke kumu valve
Palena Mahana: Ka lewa inert: -200 degere a +500 degere ; kaiapuni hoʻoheheʻe ʻia: ʻōlelo ʻia ʻaʻole emi a like paha me ka +400 degere /+450 degere; ʻaʻohe heheʻe, paʻakikī a hoʻohaʻahaʻa paha
Lubricating pono'ī: Graphite (lubricant paʻa) hoʻemi i ka ʻāʻī ʻana o ke kumu valve a me ka torque hana; hōʻoia i ka hana maʻemaʻe, pale i ke kumu valve mai ka ʻaʻahu
Kemika Inertness: Kūʻē nui i nā ʻakika like ʻole, alkalis, solvents, organic compounds; kūpono no nā hana kemika corrosive
Ka hoʻouka ʻana: Corrugated structure me ka maʻalahi a me ka paʻakikī; maʻalahi e hoʻopili i ke kumu valve, e like me ka geometry pahu pahu; ʻaʻole pono nā mea hana kūikawā
Ke Ola Hana: Kūʻē -ʻelemakule, kū i nā pōʻai wela a me nā haʻalulu; hōʻemi i ka manawa hoʻomaha o ka mālama ʻana, ka pinepine o ka hoʻololi ʻana a me ka nui o ke kumu kūʻai
3. Nā noi nui
Hoʻohana nui ʻia i nā valve ʻoihana e koi ana i ka hoʻopaʻa paʻa ʻana, e komo pū ana akā ʻaʻole i kaupalena ʻia i:
Kemika a me ka Petrochemical: ʻO nā ʻīpuka (puka, ka honua, ka poepoe, ka hoʻoponopono ʻana) i nā reactors, pipelines, pumps
Ka Mana Mana: E puhi -i na kiwi, na kiwi mokuahi ma na mea kanu
Laʻau Lapaʻau a me ka Meaʻai: Nā ʻūpā no ka hoʻomaʻemaʻe-pono koʻikoʻi
Metallurgical: Kiʻekiʻe -wela wela wela kiʻekiʻe, kinoea kiwikā
Pepa: Kaʻina hana nā kiwikā e lawelawe ana i nā kemika corrosive
4. Nā ʻāpana ʻenehana maʻamau
