1. Hoʻokaʻawale ʻana o ke kumu hoʻohālike ʻaila hydraulic
Ua hoʻokaʻawale ʻia nā kumu hoʻohālike aila hydraulic i ʻekolu mau māhele maʻamau aupuni: ʻano HL, ʻano HM, a me ke ʻano HG.
(1) Ua hana ʻia ka ʻaila hydraulic ʻano HL mai kahi ʻaila kumu waena i hoʻomaʻemaʻe ʻia, hohonu kiʻekiʻe, me nā mea hoʻohui antioxidant a me anti-rust. Wahi a ka neʻe ʻana ma 40 degere Celsius, hiki ke hoʻokaʻawale ʻia ka viscosity i ʻeono mau papa: 15, 22, 32, 46, 68, a me 100.
(2) ʻO nā ʻano HM e komo pū ana me ke ʻano alkaline kiʻekiʻe, alkaline haʻahaʻa zinc, neutral high zinc a me nā ʻano lehu ʻole. Wahi a ka neʻe ʻana ma 40 degere Celsius, ua māhele ʻia ka viscosity i ʻehā mau papa: 22, 32, 46, a me 68.
(3) Loaʻa i ke ʻano HG nā waiwai anti-rust a me anti-oxidation. Eia kekahi, ua hoʻohui ʻia kahi mea hoʻomaikaʻi index viscosity, nona nā ʻano viscosity-temperature maikaʻi.
2. Hoʻohana ʻana i ke kumu hoʻohālike ʻaila hydraulic
(1) Hoʻohana ʻia ka ʻaila hydraulic HL no ka lubrication i loko o nā pahu hali a me nā ʻōnaehana hoʻolaha haʻahaʻa o nā mea hana mīkini like ʻole kahi ʻaʻohe koi kūikawā no ka ʻaila a ʻoi aku ka mahana o ke ambient ma mua o ka zero degere Celsius.

(2) Hoʻohana nui ʻia ka ʻaila hydraulic HM i nā ʻōnaehana hydraulic o nā pamu vane kaumaha, medium-pressure a me ke kiʻekiʻe-pressure, nā pamu plunger a me nā pamu gear. Eia kekahi, kūpono hoʻi kēia ʻano ʻaila hydraulic no nā lako ʻenekinia medium-pressure a me ke kiʻekiʻe-pressure a me nā ʻōnaehana hydraulic kaʻa.
(3) Loaʻa i ka ʻaila hydraulic HG nā waiwai anti-rust, anti-oxidation, anti-wear, a me anti-stick-slip maikaʻi, no laila kūpono ia no nā ʻōnaehana lubrication e hoʻohana ana i nā hydraulics mīkini hana a me nā ala alakaʻi.

Nui nā ʻano ʻaila hydraulic ma ka mākeke, a nui nō hoʻi nā ʻano mīkini hydraulic. ʻOiai like nā hana o ka ʻaila hydraulic, pono nō e koho i nā ʻaila hydraulic like ʻole no nā mīkini hydraulic like ʻole. I ke koho ʻana i ka ʻaila hydraulic, pono e hoʻomaopopo nā limahana i ka mea nui e noi ʻia ai e hana, a laila koho i ka ʻaila hydraulic kūpono no ka mīkini hydraulic.
Pehea e koho ai i ka ʻaila hydraulic kūpono no ka mīkini paʻi hydraulic
ʻElua mau ʻano hana e hoʻohana pinepine ʻia i ke koho ʻana i ka ʻaila hydraulic. ʻO kekahi, ʻo ke koho ʻana i ka ʻaila hydraulic e like me nā ʻano ʻaila a me nā kikoʻī i ʻōlelo ʻia e nā laʻana a i ʻole nā kuhikuhi a ka mea hana mīkini hydraulic. ʻO kekahi, ʻo ia ka noʻonoʻo piha ʻana i ke koho ʻana o ka ʻaila hydraulic e pili ana i nā kūlana kikoʻī o ka mīkini hydraulic, e like me ke kaomi hana, ka mahana hana, ka wikiwiki o ka neʻe ʻana, ke ʻano o nā ʻāpana hydraulic a me nā mea ʻē aʻe.
I ke koho ʻana, ʻo nā hana nui e hana ʻia: ke hoʻoholo ʻana i ka pae viscosity o ka ʻaila hydraulic, ke koho ʻana i ke ʻano ʻaila hydraulic kūpono, a me ka hoʻokō ʻana i nā pono kūikawā o ka ʻōnaehana hydraulic.
ʻO ka maʻamau, koho ʻia e like me kēia mau ʻano:
(1) Wahi a nā koho like ʻole o nā mīkini hana kaomi hydraulic
He ʻokoʻa nā koi viscosity o nā mīkini kikoʻī a me nā mīkini maʻamau. I mea e pale aku ai i ka deformation o nā ʻāpana mīkini i hoʻokumu ʻia e ka piʻi ʻana o ka mahana a hoʻopilikia i ka pololei o ka hana, pono nā mīkini kikoʻī e hoʻohana i ka ʻaila hydraulic me ka viscosity haʻahaʻa.
(2) Koho e like me ke ʻano o ka pamu hydraulic
He ʻāpana koʻikoʻi ka pamu hydraulic o ka mīkini paʻi hydraulic. I loko o kahi mīkini paʻi hydraulic, kiʻekiʻe kona wikiwiki neʻe, kaomi a me ka piʻi ʻana o ka mahana, a lōʻihi kona manawa hana, no laila ʻoi aku ka paʻakikī o nā koi no ka viscosity. No laila, pono e noʻonoʻo ʻia ka pamu hydraulic i ke koho ʻana i ka viscosity.
(3) Koho e like me ke kaomi hana o ka mīkini paʻi hydraulic
Ke kiʻekiʻe ke kaomi, pono e hoʻohana ʻia ka ʻaila me ka mānoanoa kiʻekiʻe e pale aku i ka leakage nui o ka ʻōnaehana a me ka pono haʻahaʻa. Ke haʻahaʻa ke kaomi hana, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka ʻaila me ka mānoanoa haʻahaʻa, hiki ke hōʻemi i ka pohō kaomi.
(4) E noʻonoʻo i ka mahana o ka wahi hana o ka mīkini paʻi hydraulic
Hoʻololi nui ka mānoanoa o ka ʻaila mineral ma muli o ka mana o ka mahana. I mea e hōʻoia ai i kahi mānoanoa kūpono i ka mahana hana, pono e noʻonoʻo ʻia ka mana o ka mahana a puni.
(5) E noʻonoʻo i ka wikiwiki o ka neʻe ʻana o nā ʻāpana hana o ka mīkini paʻi hydraulic
Ke kiʻekiʻe loa ka wikiwiki o ka neʻe ʻana o nā ʻāpana hana i loko o ka ʻōnaehana hydraulic, haʻahaʻa hoʻi ka nui o ke kahe o ka aila, piʻi ka pohō hydraulic ma ke ʻano ulia pōpilikia, a ua emi iki ka leakage, no laila ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka aila me ka viscosity haʻahaʻa.
(6) E koho i ke ʻano kūpono o ka ʻaila hydraulic
ʻO ke koho ʻana i ka ʻaila hydraulic mai nā mea hana maʻamau hiki ke hōʻemimīkini kaomi hydraulicnā hemahema a hoʻolōʻihi i ke ola o ka mīkini paʻi.
