Nā aila kaʻa - pehea e koho ai

ʻO ka hoʻopiha ʻana me ka ʻaila ʻenekini hewa hiki ke hōʻeha nui i ka mana. No ka paleʻana i nā kumukūʻai hoʻoponopono kiʻekiʻe, pono e koho i kaʻaila kūpono.

ʻO ka lula mua a me ka hoʻokahi wale nō o ka hahai ʻana i nā ʻōlelo aʻoaʻo a ka mea hana ʻenekini. ʻO nā mana mana o kēia wā he mau mīkini i hana ʻia me ka hoʻohana ʻana i nā ʻenehana hou loa a me kā lākou hoʻolālā e pili ana i nā ʻāpana. hopena. No laila, ʻo ka ʻaila ʻenekini hou he mea hoʻolālā o ka ʻenekini a no laila pono e kūlike me kāna mau mea āpau e pili ana i ka mechanical, chemical and thermal resistance.

KA HELUHELU ANA

I ka manawa hea e hoʻololi ai i ka aila?

E hoʻomanaʻo i kaʻaila i loko o ka pahu

ʻO ka hapa nui o nā ʻaila i hoʻohana ʻia i kēia lā he ʻaila synthetic, kahi e hāʻawi ai i ka pale maikaʻi loa a me ka hoʻoluʻu no ka neʻe ʻana i nā ʻāpana ʻenekini ma mua o nā aila mineral. Loaʻa iā lākou ka hiki ke hoʻokaʻawale i nā mea ʻokoʻa ma muli o ke kaʻina puhi ahi, i ʻoi aku ka maʻalahi o ka hopu ʻana e nā ʻōnaehana kānana.

ʻO ka hiʻohiʻona koʻikoʻi a maikaʻi hoʻi i ka hoʻohālikelike ʻia me nā ʻaila mineral ka haʻahaʻa haʻahaʻa o nā ʻaila synthetic, e hiki ai i ka uhi ʻaila kūpono o nā ʻili i hoʻopili ʻia i ka friction ma kahi kokoke i nā ʻano wela, ʻoi aku ka haʻahaʻa haʻahaʻa, ke mānoanoa kēlā me kēia ʻaila ʻenekini.

Mai hoʻohui i ka ʻaila synthetic me ka ʻaila mineral, a inā pēlā, me ka semi-synthetic.

Eia kekahi, mai hoʻohana i nā aila synthetic no nā ʻenekini o nā kaʻa kahiko me ka mile mile kiʻekiʻe, i hana mua ʻia me ka ʻaila mineral. Hiki i ka aila synthetic piha i kēia hihia ke hōʻeha nui, no ka mea, ʻo nā detergents a me nā mea hoʻomaʻemaʻe i hoʻokomo ʻia i loko o kāna ʻano e hoʻopau i ka lepo i hōʻiliʻili ʻia a me nā waihona e hoʻohaumia i nā ʻāpana engine. Eia kekahi, ua hana ʻia ka hapa nui o nā sila ʻenekini kahiko mai nā hoʻoheheʻe ʻia ʻana i hana ʻole ʻia e hana me nā ʻaila ʻaila synthetic. No laila ke kiʻekiʻe o ka leakage aila.

ʻO ka hope, pono nō hoʻi e hahai i ke kānāwai e hoʻohana i nā aila mai nā mea hana kaulana a ʻike ʻia, ʻoiai ʻoi aku ka kiʻekiʻe o kā lākou kūʻai kūʻai ma mua o nā mea ʻē aʻe.

ʻO nā makahiki o ka ʻike e uku mau ʻia me ka maikaʻi o ka huahana, ma ke ʻano o ka ʻaila ʻenekini, pili ka hana a me ke ola o ka mīkini o kā mākou kaʻa.

Wahi a nā kūlana SAE i ʻae ʻia, hōʻike ʻia ka viscosity aila e nā helu mai 0 a 60, a ʻo ka pālākiō 6-point "W" (hoʻoilo) mai 0W a 25W e hoʻoholo ai i ka mahana i hoʻololi ʻia ai ka viscosity a hiki i ka mānoanoa o ka ʻaila. mokuʻāina i ka hoʻomaka ʻana o ka ʻenekini lilo i mea hiki ʻole.

I ka hoʻomaʻamaʻa, e like me kēia:

– no ka viscosity grade 0W, keia wela wela mai – 30°C a i – 35°C,

- 5W - 25 a - 30 ° C,

- 10W - 20 a - 25 ° C,

- 15W - 15 ° C a i - 20 ° C,

- 20W - 10 ° C a i - 15 ° C,

- 25 W - mai -10 ° C a i 0 ° C.

ʻO ka lua o ka māhele o ka pālākiō (5-point scale, 20, 30, 40, 50 a me 60) e hoʻoholo i ka "ikaika o kaʻaila",ʻo ia hoʻi, ka mālamaʻana i nā waiwai a pau i ke kiʻekiʻe o ka mahana wela, i.e. 100°C a me 150°C.

ʻO ka viscosity index o nā aila kaʻa synthetic mai ka 0W a i ka 10W, a ua hana pinepine ʻia nā aila 10W ma ke ʻano he semi-synthetic. ʻO nā ʻaila i hoʻopaʻa ʻia he 15W a ʻoi aku ka maʻamau.

KA HELUHELU ANA

ʻAila no nā ʻenekini kinoea

E nānā i kāu aila ma mua o kou holo ʻana

Hiki ke ʻike ʻia kēia mau hōʻailona a pau ma ka pahu o kēlā me kēia ʻaila ʻenekini, akā ʻaʻole pane kā lākou loiloi i ka nīnau - hiki anei ke hui pū i nā aila, a inā pēlā, ʻo wai ka mea?

ʻOiaʻiʻo, ʻaʻohe mea ʻino e hiki mai i ka mīkini inā, ʻoiai e mālama ana i nā ʻāpana like ʻole a me ka papa viscosity, hoʻololi mākou i ka brand - ʻo ia ka mea hana. Ma hope o ke kaʻa ʻana i kahi helu nui o nā kilomika, hiki nō ke hoʻohana i ka aila o kahi māka viscosity kiʻekiʻe iki, ʻo ia hoʻi. ʻoi aku ka paʻa. ʻOi aku ka maikaʻi o ka hoʻopaʻa ʻana i ka ʻenekini, e hoʻomaikaʻi iki i kona kūlana, ʻoiai e ʻike ʻoe ʻaʻole ia e hoʻoponopono i kahi ʻenekini i pau.
