Deciphering gear aila 75W-90

Hoʻokaʻawale ʻia nā ʻaila Gear e like me nā kūlana like me nā ʻaila mīkini, akā ʻokoʻa ka papa inoa o nā ʻano ʻenehana nui. E kūkākūkā mākou i ka ʻaila ʻaila 75W-90, nā hiʻohiʻona maʻamau, nā māka a me ka hoʻokaʻawale ʻana o nā aila mai nā mea hana like ʻole.

Nā kikoʻī 75W-90

Ma ka hoʻohālikelike me ka hoʻokaʻawale ʻana o nā aila kaʻa, loaʻa ka ʻaila ʻaila i ka hoʻoilo a me ke kauwela. I ka hoʻoilo, hoʻoholo ʻia ka mahana i ka wā e mānoanoa ai ka ʻaila a ʻaʻole hiki ke hele maʻamau i nā ʻāpana āpau i ka wā hoʻomaka. Hōʻike ke kauwela i ka viscosity kinematic i ka mahana hana, ʻo ia hoʻi, pehea ka maʻalahi o ka hele ʻana o ka ʻaila ma nā ala āpau a me ka mānoanoa o ka kiʻi ʻaila. I loko o nā pahu, e like me nā mīkini, ʻokoʻa ka ākea ma waena o nā ʻāpana a pono kēlā me kēia ʻano pahu i kona viscosity ponoʻī.

Nā helu maʻamau no SAE 75W-90:

Nāʻano	Hōʻike	kope ʻia
Kinematic viscosity ma 100°C	13,5-18,5 sSt	Pono ka hōʻailona ma loko o kēia mau palena no ka hoʻopaʻa inoa ʻana o ka ʻaila 75W-90.
Lae hau	-40	Hiki ke ʻokoʻa. Hōʻike kēia hōʻailona i ka mahana kahi e maloʻo loa ai ka aila a hiki ʻole ke hele ma nā kahawai.
kiko uila	210	Hiki ke loli +/- 10-15 degere.

Nā waiwai hana o nā aila e like me ka helu API GL4, GL5

Hiki i nā aila ke like me ka SAE viscosity akā ʻokoʻa i ka API. ʻAʻole i emi iki ka ʻokoʻa o ka haku mele i ke koho ʻana:

• GL-4 - no nā pahu me ka hypoid a me ka bevel gears. Hoʻopaʻa ʻia i ka mahana a hiki i 150 degere a ma ke kaomi a hiki i 3000 MPa. ʻO ia hoʻi, no nā kaʻa kaʻa huila mua.
• GL-5 - no nā kaʻa e hana ana ma lalo o ka haʻalulu haʻalulu a me ke kaomi kiʻekiʻe - ʻoi aku ma mua o 3000 MPa. He kūpono no nā ʻūhā hypoid bevel i nā pahu pahu, nā mea hana nui me nā axles kaʻa.

He mea nui e koho pololei i ka papa i kuhikuhi ʻia e ka mea hana pahu. No ka laʻana, loaʻa i ka GL-4 nā mea hoʻohui sulfur a me ka phosphorus ma mua o GL-5. Pono kēia mau mea hoʻohui e hana i kahi pale pale e pale ai i ka lole. ʻOi aku ka ikaika o kēia mea ma mua o ke keleawe, a inā he mau mea keleawe i loko o ka pahu, e hoʻopau koke ka ʻaila brand GL-5 iā lākou.

Viscosity 75W-90 a me 80W-90: he aha ka ʻokoʻa?

E like ana ka viscosity kinematic, akā ʻoi aku ka liʻiliʻi o ka 75W. He kūpaʻa lākou i ka hau, inā loaʻa iā 75W ka paepae wela kiʻekiʻe ma ka lihi o -40 degere, a laila loaʻa iā 80W ka wela kiʻekiʻe o -26. ʻO ia hoʻi, i loko o kahi pahu anuanu e ʻike ʻia nā ʻokoʻa, akā i ka wā e wela ai, ʻaʻohe ʻokoʻa i ʻōlelo ʻia.

Hiki iā 75W-90 a me 80W-90 ke hui

Ma lalo o nā kūlana maʻamau, e ʻōlelo mau wau i hoʻokahi mea: ʻaʻole, ʻaʻole hiki iā ʻoe ke hui pū. ʻO ke kūpono, pono ʻoe e hoʻopiha i ka aila o ka like viscosity, grade a me ka mea hana. Inā ʻaʻohe ala ʻē aʻe, ʻae ʻia e hoʻohui i ka aila 80W-90 i ka 75W-90 a i ʻole ke ʻano, akā koho i ka papa i koi ʻia, ʻano ʻaila - synthetics, semi-synthetics a i ʻole ka wai mineral, a me ka mea hana. He kūpono kēia, akā inā ʻaʻohe mau kūlana, koho mākou i ka papa i koi ʻia e like me ka API. Ma hope o ka hui ʻana, paipai wau e hoʻololi koke i ka lubricant.

75W-90

ʻO ka hiʻohiʻona Gear 300

Ua loaʻa iā ia kahi helu kiʻekiʻe ma muli o ka pale maikaʻi ʻana i kahi stalker - he index o 60,1. ʻO nā hōʻailona maikaʻi loa o ka nui a me ka mahana, mānoanoa nui ma -60 degere, ʻaʻole maikaʻi no 75W.

Ua ninini ʻia i loko o nā pahu pahu kaʻa haʻuki, hoʻoili ʻia a me ka hoʻoili lima ʻole ʻia, non-locking hypoid type axles e hana ana ma ka haʻahaʻa kiʻekiʻe a me ka wikiwiki haʻahaʻa.

Wahi a API, aia ia i nā papa GL-4 a me GL-5.

ʻO Castrol Syntrans Transaxle

ʻO ka aila Synthetic me ke kaomi koʻikoʻi maikaʻi loa a me nā waiwai antiwear, ʻo ka hui pū kekahi pūʻulu o nā mea hoʻohui kūikawā. Wahi a API GL-4+. He kūpono no ka hoʻoili lima lima, nā hoʻoili poloka me ka hoʻokele hope o ka axle kaʻa mua, nā hihia hoʻoili a me nā hoʻokele hope. Nalo ka wai ma kahi haʻahaʻa haʻahaʻa haʻahaʻa ma mua o ka mua - 54 degere ma lalo o ka ʻole. He kūpono no ka hoʻohana lōʻihi.

Mobile Mobilube 1 SHC

ʻO ka huahana Synthetic me kahi paʻakikī o nā mea hoʻohui hou. Paʻa ma luna o kahi ākea o nā wela, nā kaomi kiʻekiʻe a me nā haʻalulu haʻalulu. Ua like ka paepae maloʻo: 54 degere me ka hōʻailona hōʻemi, ʻaʻole maikaʻi no 75W.

Kūpono nā māka API GL-4 a me GL-5 no nā noi hana kaumaha kahi e koi ʻia ai nā koi koi kiʻekiʻe. Hiki ke ninini ʻia i loko o nā kaʻa a me nā kaʻa, minibuses, SUVs, kūkulu a me nā mīkini mahiʻai. Loaʻa iā ia kahi papa inoa o nā ʻae mai nā mea hana hoʻouna.

Ka huina hooili SYN FE

ʻO ka aila me nā waiwai hana maikaʻi e ninini ʻia i loko o nā mea hoʻouka nui a hoʻokele axles, ʻo ia hoʻi, i nā hihia kahi i kau ʻia ai kahi ukana nui ma ka hoʻouna. Mālama i ka viscosity ma luna o kahi ākea ākea a pale a lubricates ma lalo o nā kūlana hana koʻikoʻi. He kūpono no nā mīkini hypoid a me nā shaft i hoʻonohonoho ʻia me ka hoʻouna lima. Hiki iā ʻoe ke hoʻonui i ka wā hoʻololi, aia ka nui o nā tolerances mai nā mea hana pahu.

LIQUI MOLY Hypoid Gear Oil TDL

Wahi a nā papa API GL-4, GL-5. Nā hopena ho'āʻo maikaʻi, hoʻohana ma -40. ʻO kekahi mau hōʻailona aila ʻē aʻe ma mua o ka awelika e pili ana i nā mea hoʻokūkū, no laila ʻaʻole ia e lawe i kahi mua.

Semi-synthetic, hiki ke ninini ʻia i loko o nā hoʻolālā pahu pahu like ʻole. Eia kekahi, he haʻahaʻa haʻahaʻa kona kumukūʻai.

ʻŌlelo wau ʻo GF TOP

synthetic Korean. E mālama i ka wai ma nā haʻahaʻa haʻahaʻa, e hōʻike ana i nā hopena maikaʻi ma nā mahana kiʻekiʻe, ʻo ia hoʻi ke kūʻē maikaʻi i ka lole. Wahi a nā loiloi o nā mea nona nā kaʻa, me kēia ʻaila e hana mālie ka pahu me ka mālie a hiki i ke anuanu. Hiki ke hoʻohana ʻia i nā hoʻoili lima, nā axles a me nā ʻāpana no ka mea ʻaʻohe koi o ka mea hana hou no ka wai i hoʻohana ʻia. Lilo ka wai wale ma -45 degere.
