Hoʻohana ʻo Valve internals i nā kaiapuni koʻikoʻi loa, e kū ana:
Erosion: Hoʻokumu ʻia e ka wikiwiki kiʻekiʻe a i ʻole nā wai i hoʻopiha ʻia.
ʻAiʻino: Mai nā mea hoʻopāpā kemika.
Cavitation: ʻO ka hana ʻana a me ka hāʻule ʻana o nā ʻōpū mahu, e hoʻoulu ai i ka lua o ka ʻili.
Kiʻekiʻe-Pressure/Mamahana: Ke alakaʻi nei i ka galling (ʻaʻahu adhesive) a me ka deformation.
No ka hakakā ʻana i kēia mau pilikia, hana pinepine ʻia nā valve internals mai a pale ʻia paha e nā mea kiʻekiʻe, me ka tungsten carbide he koho nui loa no nā lawelawe koʻikoʻi.
Hōʻuluʻulu ka papa ma lalo nei i nā valve internals maʻamau, ko lākou mau pilikia, a me nā ʻōnaehana maʻamau:
| ʻāpana | Hana | Mechanism Wear Wear | Nā Mea Hana Maʻamau |
| Noho | Hāʻawi i kahi ili hoʻopaʻa no ka pani ʻana. | ʻAiʻi, Cavitation, Galling, Corrosion. | Tungsten Carbide, Stellite (Cobalt-Chrome), 316SS, Alloy 6, Keramika. |
| Lala Pani (Plug/Disc) | Neʻe e wehe/pani i ke ala kahe. | ʻAiʻi, Cavitation, Galling, Corrosion. | Tungsten Carbide, Stellite, 316SS, Na kila paa. |
| Ke kumu | Hoʻouna i ka neʻe mai ka mea hana i ka lālā pani. | Abrasion, Fatigue, Corrosion. | 17-4PH Kuhiliʻole, Nā kila Nitrided, nā Alloys kūʻē i ka ʻino. |
| Cage | Alakaʻi i ka plug a hoʻomalu i nā ʻano kahe. | ʻAi ʻino, Cavitation, Noise/Vibration. | Tungsten Carbide, Stellite, 316SS, Na kila kuhiliʻole Duplex. |
| Na Sila & Puke | Kāohi i waho a me loko leakage. | Extrusion, Hoʻohaʻahaʻa Kemika, Hoʻomāmā. | PTFE (Teflon), Grafoil, Elastomers (Viton, EPDM). |
No ke aha ʻo Tungsten Carbide no nā Valve Internals?
I nā noi koʻikoʻi i loaʻa i ka ʻaila a me ke kinoea, ka hana mana, a me nā ʻoihana hoʻoili kemika, tungsten carbide ua kuhikuhi ʻia no nā ʻāpana ʻokiʻoki ma muli o kāna:
Kū'ē Kū'ē Kū'ē: No ka pale ʻana i ke one a me nā mea paʻakikī ʻē aʻe i ke kahawai wai.
Kū'ē Cavitation Kū'ē: ʻO kona paʻakikī ke pale aku i ka nalowale waiwai mai ka hoʻohūhū ʻana i nā ʻōpū mahu.
Kiekie Compressive ikaika: E pale i ka deformation ma lalo o ke kaomi kiʻekiʻe.
Kū'ē Galling maikaʻi: Ke hoʻopili ʻia me kahi mea kūpono, hoʻemi ia i ka pilikia o ka hopu ʻana.
I ka hōʻuluʻulu manaʻo, ʻO loko o ka valve ʻo ia ka puʻuwai o ka valve. ʻO kā lākou koho, ʻoi aku ka maikaʻi o ke koho ʻana i nā mea ʻaʻahu e like me tungsten carbide no nā ʻāpana ʻoki, he hoʻoholo ʻenehana koʻikoʻi e hoʻoholo pololei i ka hana o ka valve, ke ola lawelawe, a me ka palekana ʻōnaehana holoʻokoʻa i nā kūlana hana paʻakikī.
