ʻO kaPapa Kuhikuhi Mānoanoa (VI)he helu ia e hōʻike ana i ka nui o ka loli ʻana o ka mānoanoa o kahi wai me ka mahana. He ana hoʻohālikelike ʻole ia—ʻo ia hoʻi, ʻaʻohe ona anakahi a hoʻohana ʻia e hoʻohālikelike i nā wai. Akiʻekiʻe VIʻo ia hoʻi ke kūpaʻa nei ka viscosity o ka wai ma kahi ākea o ka mahana, ʻoiai hehaʻahaʻa VIʻo ia hoʻi, loli nui ka mānoanoa (viscosity), e hoʻemi ana i ka hilinaʻi o ka wai i nā mahana koʻikoʻi.
No ke aha he mea nui ka VI?
I nā noi honua maoli, nā wai e like me nā aila kaʻa a i ʻolenā wai hydraulicpono e hana pono ma nā ʻano mahana like ʻole. Inā loli nui ka mānoanoa:
- Ke anuHiki i ka wai mānoanoa ke paʻakikī i ka hoʻomaka ʻana o ka ʻenekini a i ʻole ka mīkini, e hoʻonui ana i ka ʻaʻahu ʻana ma nā ʻāpana no ka mea ʻaʻole kahe maikaʻi ka wai e lubricate iā lākou.
- Ke welaʻAʻole paha e hāʻawi ka wai lahilahi i ka palekana lawa, e alakaʻi ana i ka hoʻopā ʻana o ka metala ma luna o ka metala, ka ʻaʻahu ʻana, a i ʻole ka hāʻule ʻana o nā lako.
Eia kekahi laʻana, i loko o kahi ʻenekini kaʻa:
- I ke kakahiaka anu o ka hoʻoilo, hiki i ka ʻaila haʻahaʻa-VI ke mānoanoa loa a paʻakikī i ka ʻenekini ke huli, e hana ai i ke kaumaha a me ke komo ʻana.
- I ka wela o ke kauwela, hiki i kēlā aila haʻahaʻa-VI like ke lilo i mea lahilahi loa, a hiki ʻole ke pale i nā ʻāpana mīkini mai ka hakakā a me ka wela, e hōʻemi ana i ka pono a me ke ola.
ʻO ka aila VI kiʻekiʻe, ma ka ʻaoʻao ʻē aʻe, kahe maikaʻi ia i ke anu e hōʻoia i ka hoʻomaka mālie ʻana a noho mānoanoa i ka wela e pale i nā ʻāpana ʻenekini, e hoʻomaikaʻi ana i ka hana a me ke kūpaʻa.
Nā Kumu e Hoʻohuli ai i ka Viscosity Index
ʻO ka VI o kahi wai e pili ana i ʻelua mau kumu nui:
- ʻAno ʻaila kumu:
- Nā ʻAila Mineral(mai ka ʻaila maka): ʻO ka maʻamau, he haʻahaʻa ka VI o kēia mau mea (e laʻa, 80–120), ʻo ia hoʻi, loli nui ko lākou mānoanoa me ka mahana.
- Nā ʻaila hana(e like me nā polyalphaolefins a i ʻole nā esters): Loaʻa pinepine i kēia mau mea ka VI kiʻekiʻe aʻe (e laʻa, 120–200), e hāʻawi ana i ka kūpaʻa maikaʻi aʻe ma waena o nā mahana.
- Nā ʻAila Mea Kanu a i ʻole Bio-basedʻOkoʻa ka VI akā pinepine ia he kaulike, ma muli o ke kumu.
- Nā mea hoʻohui: Nā kemika kūikawā i kapa ʻianā mea hoʻomaikaʻi i ka helu viscosityHoʻohui ʻia nā (VII) i nā aila e hoʻonui i ko lākou VI. ʻO kēia mau mea hoʻohui he mau polymers e hoʻonui i ka wā e hoʻomehana ʻia ai, e kōkua ana i ka aila e pale aku i ka lahilahi, a ʻuʻuku i ka wā e hoʻomaʻalili ʻia ai, e pale ana iā ia mai ka lilo ʻana i mānoanoa loa.
No ke aha he mea koʻikoʻi ʻo VI i ke koho ʻana i ka wai
He mea nui ke koho ʻana i kahi wai me ka VI kūpono no nā noi kahi e loli ai nā mahana, e like me:
- Nā ʻenekini kaʻaʻO nā aila High-VI (e laʻa, synthetic 5W-30) e hōʻoia i nā hoʻomaka anu maʻalahi a me ka palekana hilinaʻi i nā mahana hana kiʻekiʻe.
- Nā ʻōnaehana hydraulicI loko o nā lako hana kūkulu, mālama nā wai kiʻekiʻe-VI i ka hāʻawi mana mau i nā wahi hau a wela paha.
- Nā mīkini ʻoihanaHoʻemi nā lubricants High-VI i ka ʻaʻahu a me ka pohō ikehu i loko o nā pahu pahu a i ʻole nā compressors e hana ana ma nā pae mahana ākea.
Eia kekahi laʻana, i ke aniau anuanu, hiki i kahi mea ʻeli hydraulic e hoʻohana ana i kahi wai haʻahaʻa-VI ke pane lohi i ke kakahiaka, e hoʻopaneʻe ana i ka hana a me ke kaumaha ʻana i nā ʻāpana. Mālama ka wai kiʻekiʻe-VI i ka ʻōnaehana e pane a me ka pono.
Ke Nānā ʻana i ka Viscosity Index
E noʻonoʻo i kahi pakuhi e hoʻohālikelike ana i ka loli ʻana o ka viscosity me ka mahana no ʻelua mau aila:
- ʻAki-XKa mahana (e laʻa, mai -20°C a i 100°C).
- ʻO ke koʻi YKa mānoanoa a ka lahilahi paha o ke wai.
- ʻAila haʻahaʻa-VIPiʻi nui ke kaha, e hōʻike ana i kahi loli nui o ka mānoanoa—mānoanoa loa i nā mahana haʻahaʻa a lahilahi loa i nā mahana kiʻekiʻe.
- ʻAila kiʻekiʻe-VIʻOi aku ka palahalaha o ka laina, e hōʻike ana e noho mau ana ka mānoanoa ma waena o ka pae mahana like.
ʻO kēia ʻokoʻa ke kumu e makemake ʻia ai nā aila kiʻekiʻe-VI no nā noi koi—hāʻawi lākou i ka hana i wānana ʻia a hilinaʻi hoʻi.
Nā Manaʻo Koʻikoʻi
- Papa Kuhikuhi Mānoanoa (VI)ana i ke kūpaʻa o ka mānoanoa o kahi wai i ka loli ʻana o ka mahana.
- Kiʻekiʻe VI= ka mānoanoa paʻa, ʻoi aku ka maikaʻi no nā pae mahana ākea (e laʻa me nā aila synthetic).
- Haʻahaʻa VI= loli nui ka mānoanoa, hiki ke hana i nā pilikia i nā kūlana anu a wela paha.
- Ka hopena o ke ao maoliHoʻomaikaʻi nā wai kiʻekiʻe-VI i ka hana a me ka pale ʻana i nā ʻenekini, nā ʻōnaehana hydraulic, a me nā mīkini ma ka hōʻemi ʻana i ke komo ʻana a me ka hōʻoia ʻana i ka hana maʻalahi.
- Nā kumuʻO ke ʻano aila kumu (mineral vs. synthetic) a me nā mea hoʻohui e like me nā mea hoʻomaikaʻi index viscosity e hoʻoholo ai i ka VI.
Ma ke koho ʻana i kahi wai me ka VI kūpono, hiki i nā ʻenekinia a me nā mea loea ke hōʻoia i ka holo pono ʻana o nā lako a lōʻihi ka lōʻihi, me ka nānā ʻole i ke aniau a i ʻole nā kūlana hana.
