ʻO ka wai wili hea e koho ai no kahi kaʻa?
Nā mea
Inā loaʻa iā ʻoe kekahi ʻano kaʻa, pono ʻoe e hoʻomaopopo pono inā makemake ʻoe e palekana i ke ala, pono ʻoe e hoʻolako i ka ʻōnaehana palaka o kāu kaʻa me ka wai wili maikaʻi loa.
ʻO ka wai wili hea e koho ai
E hoʻomaopopo ʻoe i kēia wai ke kumu o ka hana pono o ka wawahi a hilinaʻi nui i ka hiki i kāu kaʻa ke kū i ka manawa ke hoʻopili ʻoe i nā paleki.
Eia nō naʻe, i kekahi manawa, no ka poʻe hoʻokele hoʻi i loaʻa ʻole ka ʻike nui i ka lawelawe ʻana i nā kaʻa, paʻakikī e hana i kahi koho maikaʻi loa o ka wai wili no ke ʻano kaʻa a lākou.
I mea e wehewehe iki ai i kēia pilikia, ua hoʻomākaukau mākou i kēia mea, me ka manaʻolana e hiki ai iā mākou ke pōmaikaʻi i nā mea hoʻokele novice a me ka ʻike.
ʻO ka wai wili hea e koho ai no kahi kaʻa?
Ma mua o kā mākou kamaʻilio ʻana e pili ana i nā mana o nā wai hoʻoheheʻe i loaʻa ma ka mākeke, pono ʻoe e ʻike i kahi mea a ʻelua paha e pili ana i kēia wai.
He aha ka wai wawahi?
Hiki ke kapa maʻalahi ʻia kēia wai he wai neʻeneʻe, ka mea ma ka hoʻomaʻamaʻa he wai ia, ma o kāna neʻe ʻana, kākoʻo i ka hana o nā ʻōnaehana hydraulic.
He mea kūikawā ka wana a ke hana ia ma lalo o nā ʻano hana ʻoi loa a pono e hoʻokō i kekahi mau ʻano, e like me ke kūpaʻa wela kiʻekiʻe, ʻaʻohe popopo, viscosity maikaʻi, a pēlā aku.
Ua koho ʻia ʻo DOT i nā ʻano wai
Hoʻokaʻawale ʻia nā wai wili āpau e like me nā kikoʻī ʻo DOT (Keʻena Kaʻa Uwi), a ʻo kēia kahi e hoʻomaka ai me ke koho ʻana i ka wai wili no kāu kaʻa.
ʻEhā mau ʻano o nā wai hoʻoheheʻe e like me kēia kikoʻī. He ʻano like kekahi o lākou, ʻokoʻa ʻokoʻa nā mea ʻē aʻe.
DOTS 3
Hana ʻia kēia ʻano wai hoʻoheheʻe hydraulic mai polyglycol. ʻO kona kiko paila ma kahi o 140 kekelē Celsius a ʻo kona kiko paila maloʻo he 205 kekelē. Hoʻokomo ʻo DOT 3 i ka wai ma 2% no hoʻokahi makahiki.
Hoʻohana nui ʻia kēia ʻano wili hoʻoheheʻe i nā kaʻa hana haʻahaʻa. (No nā kaʻa kahiko, nā paleki pahu a me nā kaʻa maʻamau maʻamau).
DOTS 4
Hoʻokumu ʻia kēia wai i ka polyglycol, e like me ka mana mua. He 4 degere Celsius ko DOT 155 a he wahi paila maloʻo a hiki i 230 degere. E like me DOT 3, hoʻomoʻa kēia wai i ka 2% o ka makū i loko o ka makahiki, akā he hoʻokahi pono koʻikoʻi ma luna o ia mea, ʻo ia hoʻi ka pae hoʻolapalapa kiʻekiʻe, e kūpono ai ia no nā kaʻa nui a me nā SUV hana kiʻekiʻe.
DOTS 5.1
ʻO kēia ke ʻano hope loa o ka wai kaʻa i hana ʻia mai polyglycols. Ke hoʻohālikelike ʻia me nā ʻano wai ʻelua ʻē aʻe, ʻo DOT 5.1 ka mea kiʻekiʻe loa o ka wai a maloʻo hoʻi ka paila (mā - 180 degere C, maloʻo - 260 degere C). E like me nā ʻano ʻano ʻē aʻe, hoʻopau ʻo ia ma kahi o 2% o ka wai i ka makahiki.
Hoʻohana nui ʻia ka DOT 5.1 no nā kaʻa me nā ʻōnaehana ABS a i ʻole no nā kaʻa heihei.
DOTS 5
ʻAʻole like me nā ʻano wai ʻē aʻe a pau, hoʻokumu ʻia ʻo DOT 5 ma kahi hui silicone a me synthetic. He 180 degere C ka wai hoʻolapalapa a he 260 ka paila maloʻo, ʻo ia ka wai synthetic maikaʻi loa. ʻO DOT 5 he hydrophobic (ʻaʻole e komo i ka makū) a pale i ka ʻōnaehana pale mai ka ʻino. ʻO ka mea pōʻino, ʻaʻole hiki ke hui pū ʻia kēia wai me nā ʻano ʻē aʻe, ʻoi aku ke kiʻekiʻe o kona kumukūʻai ma mua o ke kumukūʻai o nā wai glycol, kahi e kūʻai paʻakikī loa ai.
Hiki ke hoʻohana ʻia kēia wai i nā kaʻa a nā mea hana i hōʻike pono ai i kāna hoʻohana ʻana e kaupalena nui ana i nā kaʻa kaʻa a me nā māka i hiki ai ke hoʻohana. Hoʻohana mau ʻia ʻo DOT 5 i nā kaʻa hana kiʻekiʻe i kēia manawa, nā ʻōnaehana hoʻopaʻa paʻa anti-laka, a me nā hoʻohālikelike kaʻa heihei.
ʻO ka wai wili hea e koho ai no kahi kaʻa?
Hele mai mākou i ka nīnau nui loa. ʻO ka ʻoiaʻiʻo hōʻike nā mea hana i ke ʻano o ka wai e kūpono i ke k forkohu a hana i ke kaʻa, akā ʻaʻole e hōʻike i ka mana e hoʻohana ai.
Hoʻopilikia nā mea like ʻole i ke koho ʻana o ka wai hoʻoheheʻe kūpono no kāu kaʻa, e like me ka nui o kāu kaʻa, pehea ka nui, inā lako me ABS a i ʻole ka traction control, ka mea a ka mea hana e koi ai, etc.
Eia nō naʻe, he aha ka mea e noʻonoʻo ai i ke koho ʻana i kahi wai wili no kāu kaʻa.
Holomua
E like me ka mea i ʻōlelo ʻia, hoʻolālā ʻia kekahi ʻano o nā wai hoʻoheheʻe no ka hana haʻahaʻa, ʻo nā mea ʻē aʻe no ka hana kiʻekiʻe, a ʻo nā mea ʻē aʻe no nā haʻuki a me nā kaʻa koa paha. No laila, ke koho ʻana i kahi wai e hana nei no kāu kaʻa kaʻa, koho i kahi i kuhikuhi ʻia e ka mea hana.
'Ohui
ʻO ka maʻamau o ka wai hoʻomaha he 60-90% polyglycol, 5-30% lubricant a me 2-3% additives. ʻO Polyglycol ka mea nui o ka wai hydraulic, mahalo i hiki i ka wai ke hana me ka pilikia ʻole i nā kūlana wela.
Hoʻohana ʻia nā lubricants i ka wai hoʻoheheʻe e hoʻoliʻiliʻi i ka huki frictional a hoʻomaikaʻi i ke kūlana wai.
Loaʻa nā mea hoʻohui i nā antioxidant a me nā mea hoʻowahawaha ka popopo. Aia lākou i ka wai wili no ka mea hoʻemi lākou i ka hoʻohaʻahaʻa oxidative o polyglycols, pale a hoʻemi i ka helu o ka haki acid o ka wai, a pale i ka mānoanoa o ka wai.
Kahi kiko maloʻo a pulu hoʻi
Ua hōʻike mua mākou i nā wahi paila maloʻo a pulu hoʻi o kēlā me kēia ʻano o nā wīwī, akā e ʻoi aku ka maopopo. ... ʻO ke kiko paila maloʻo e pili ana i ka wahi paila o kahi wai i hou (ʻaʻole i hoʻohui ʻia i nā paleki o ke kaʻa) a ʻaʻohe ona ona). ʻO ke kiko paila pulu e pili ana i ka wahi paila o kahi wai i komo i kahi pākēneka o ka hou.
Ka omo wai
Polyglycolic wawahi wai i hygroscopic a ma hope o kekahi manawa hoʻomaka lākou e omo ona mau. ʻO ka nui o ke komo i loko o lākou, ʻo ka nui o ka waiwai o kā lākou waiwai a, no laila, e emi ana kā lākou hopena.
No laila, ke koho ʻana i kahi wai e hana nei no kāu kaʻa, e hoʻolohe i ka% o ka lawe ʻana o ka wai o ka wai paʻa. Koho mau i kahi wai me ka haʻahaʻa% no ka mea ʻo ia ka mea e pale aku i ka ʻōnaehana paleki o kāu kaʻa mai ka ʻaʻai.
ka nui
Piliwi paha ʻaʻole paha, nui ka nui. Ke kamaʻilio nei mākou e pili ana i kēia no ka mea he nui nā mana o nā wai hoʻoheheʻe e hele mai i nā liʻiliʻi / ka nui, ʻo ia hoʻi ʻoe e kūʻai i mau ʻōmole inā pono ʻoe e hoʻopiha a hoʻololi loa paha i ka wai wili. A ʻaʻole maikaʻi ia nā kālā iā ʻoe.
Nā mana kaulana o nā wai wili
Huina HBF 4
Kaulana loa kēia māka i ko mākou ʻāina. Paipai ʻia no nā ʻōnaehana hydraulic o nā ʻano kaʻa like ʻole e hoʻohana ana i nā wai synthetic DOT 4.
ʻO ka huina HBF 4 he kiʻekiʻe loa kahi maloʻo a pulu hoʻi, he kūpikipiki kūʻē, kūpaʻa i ka omo wai a he viscosity kūpono ia no nā mahana maikaʻi ʻole a kiʻekiʻe loa hoʻi.
Loaʻa ka huina HBF 4 wīwī i ka nui, 500 ml. ʻōmole, a ʻoi aku ka maikaʻi o kāna kumu kūʻai. Hiki ke hoʻohui ʻia me nā wai wana synthetic a pau o ke ʻano like. Mai kāwili pū me nā wai wai a me nā wai silikone.
ʻO ka mākia ʻo DOT 4
He hana kiʻekiʻe loa kēia wai paʻa a hāʻawi i ka mana lawa i ka ʻōnaehana paʻa. Loaʻa ia i loko o nā ʻōmole 500 ml, kahi nui i hiki iā ʻoe ke hoʻohana i nā manawa he nui. Kūpono ka huahana no nā ʻano kaʻa kaʻa a pau.
Castrol 12614 DOT 4
He inoa kaulana ʻo Castrol e hāʻawi ana i nā huahana kiʻekiʻe. ʻO Castrol DOT 4 kahi wai hoʻomaha i hana ʻia mai nā polyglycols. Mālama ka wai i ka corrosion, hiki ke hana i nā wela kiʻekiʻe a loaʻa ka waiwai wai. ʻO ka hemahema o Castrol DOT 4, ʻaʻole kūpono ia no nā kaʻa maʻamau, no ka mea, ua hoʻolālā ʻia no nā kaʻa ikaika a hana maikaʻi loa i nā kaʻa hana kiʻekiʻe.
Motul RBF600 DOT 4
Ma mua o ka nui o nā huahana DOT 3 a me DOT 4. ʻoi aku ka nui o nā palena i ʻike ʻia i kēia wai mai nā poʻe ʻē aʻe. Motul RBF600 DOT 4 waiwai i ka nitrogen, no laila he lōʻihi ʻoi aku kona ola a ʻoi aku ka pale aku i ka haumia. Hoʻohui ʻia, he wahi kohua kiʻekiʻe loa ia, pulu a maloʻo hoʻi, e kūpono ai no nā heihei a me nā kaʻa hana kiʻekiʻe. ʻO nā mea maikaʻi ʻole o kēia k modelkohu a me ka wai o ka wili wili ke kumu kūʻai kiʻekiʻe a me ka liʻiliʻi o nā ʻōmole kahi i hāʻawi ʻia ai.
Prestone AS401 – DOT 3
E like me DOT 3, he haʻahaʻa ko Prestone ma mua o nā huahana DOT 4, akā ke hoʻohālikelike ʻia me nā huahana ʻē aʻe o ka papa, ua ʻoi aku ka maikaʻi o kēia ʻano kīʻaha a ʻoi aku ka maikaʻi ma mua o nā wahi paila liʻiliʻi. hoʻoholo ʻia e DOT. Inā e holo ana kāu kaʻa ma ka wai DOT 3 a makemake ʻoe e hoʻomaikaʻi i ka hana o kāu wai kaʻa, ʻo Prestone AS401 ka wai no ʻoe.
ʻO nā mana a me nā hoʻohālikelike o nā wai wili a mākou i hōʻike aku ai iā ʻoe e hōʻike ana i kahi hapa liʻiliʻi o nā wai neea i loaʻa ma ka mākeke, a hiki iā ʻoe ke koho i kahi mana ʻē aʻe āu e makemake nui ai.
I kēia hihia, ʻo ka mea ʻoi aku ka nui ʻaʻole ka lepili hea āu e makemake ai, akā ʻo ka lepe hea o ka wai hoʻoheheʻe āu e koho ai no kāu kaʻa ponoʻī.
Nā nīnau a me nā pane:
He aha ka mea maikaʻi loa o ka pauka? Wahi a nā kaʻa kaʻa he nui, ʻo Liqui Moly Bremsenflussigkeit DOT4 ka wai ʻoi loa. He wahi paila kiʻekiʻe kona (155-230 degere).
He aha nā wai hoʻoheheʻe i kūlike? ʻAʻole ʻōlelo ka poʻe loea i ka hui ʻana i nā ʻano wai ʻenehana. Akā ma ke ʻano he ʻokoʻa, hiki iā ʻoe ke hoʻohui iā DOT3, DOT4, DOT5.1. ʻAʻole kūpono ka wai DOT5.
He aha ka waihoʻoluʻu o DOT 4 ka wai hoʻomaha? Ma waho aʻe o nā hōʻailona, ʻokoʻa ka waihoʻoluʻu o nā wai hoʻomaha. No DOT4, DOT1, DOT3 he melemele (nā aka like ʻole). DOT5 ʻulaʻula a ʻulaʻula paha.
