I kēia manawa, hoʻohana nui ʻia ka ʻōnaehana valve enā mea hana pneumatic, nā mea hana uilaa me nā mea hana electro-hydraulic.E like me nā hiʻohiʻona o nā mea hoʻokele ʻekolu, ke nānā nei mākou i kā lākou noi i ka ʻōnaehana valve:

Pūnaehana Pneumatic: Ke hilinaʻi nei ka ʻōnaehana pneumatic i ka Air compressor, ka mea e hoʻopaʻa i ka ea, hoʻomaʻemaʻe iā ia, hoʻolako i ka mea hana pneumatic, a hoʻokele i ka valve.Hoʻokuʻu pololei ʻia ke kinoea i ka lewa i ke kaʻina o ka hoʻokele ʻana i ka mea hoʻokele, a pono ka ʻōnaehana ala kinoea e hana mau i ke kumu kinoea.No laila, ea compressor ma ka laulā pono e hoʻohana i kekahi, ke alanui nui a me ka actuator ma mua o ka lālā o ka ea lawelawe 'āpana, e like me ka dryer, kānana decompression, aila noe, etc. Pono ka mālama mau, pani.He nui nā hui ala ea, a pono pū ka nānā mau ʻana e pale i ka leaka o ka ea a pili i ke kaomi ʻōnaehana.ʻO ia hana paʻakikī wale nō e hōʻoia i ka pono o ka ʻōnaehana pneumatic actuator e hoʻololi i ka hana kūpono.ʻO ka mea hana pneumatic o ka valve anawaena nui, ʻo ia hoʻi, ka cylinder, ke koho maʻamau e like me ke kaomi kumu ea, akā ʻaʻole e neʻe pinepine ka mea hana pneumatic, a i ʻole ka hana, a lohi paha ka hana a me ka hana. ʻaʻole maʻemaʻe Ma muli o kēia mau mea:

Ke loaʻa ka makū o ke ala ea, inā ʻoi aku ka mahana o ka ea ma lalo o ka zero, e maloʻo ka wai, e hoʻoheheʻe i ka mea hana pneumatic, i hiki ʻole i ka mea hana pneumatic ke neʻe.

ʻAʻole lubricated ke ala kinoea e ka noe aila, no laila ua maloʻo ka actuator no ka manawa lōʻihi, kahi e hoʻonui nui ai ka friction.Paʻa a ʻaʻole hiki ke neʻe ka mea hana.

ʻAʻole lawa ka paʻi puka o ka ea compressor a i ʻole he leak i ke ala ea, kahi e hiki ʻole ai i ka mea hoʻokele pneumatic ke loaʻa i ka torque hoʻokele e wehe koke i ka valve a i ʻole e pani pono i ka valve.

ʻO ka ʻokoʻa o ka coefficient o ka hoʻonui wela o ke kinoea ma kahi ʻoi aku ka maikaʻi a me ka wela e alakaʻi i ka ʻokoʻa o ka manawa huakaʻi holoʻokoʻa o ka mea hana pneumatic.

He compressibility ke kinoea, hiki i ka mea hana pneumatic ke holo i ke kaʻina hana ʻaʻole maʻalahi, ka neʻe hewa koke.

Inā hoʻopaʻa wikiwiki ka noi, e hoʻolako pinepine ʻia ka mea hana pneumatic me kahi pahu kinoea ponoʻī, ma Fast shut-off, ʻoiai inā ke kinoea, ʻoki ʻia ka mana, hiki ke hōʻoia i ka wikiwiki a me ka pahu, akā no ka palena. ʻaʻole pōkole loa ka manawa pani wikiwiki.

Hydraulic System: Hydraulic station system and gas system operating mechanism is like, pono e hana kiʻekiʻe-press aila, pono aila kānana, pono e waiho aila.ʻO ka ʻokoʻa hoʻi ka maikaʻi o ka ʻōnaehana hydraulic, ʻo ka ʻōnaehana hydraulic ka holo ʻana i loko, ʻo ka nui o ka ʻaila e pili ana i 40 ~ 120 kg, ʻoi aku ka liʻiliʻi o ka mea hana hydraulic ma mua o ka mea hana pneumatic, a ʻaʻohe o ka ʻaila hydraulic compressibility hydraulic cylinder holo. ʻAʻole hiki ke hele mālie ke ʻano o ka jam jitter.Hiki i ka ʻōnaehana hydraulic ke hoʻopau loa i ka hemahema o ka ʻōnaehana pneumatic.

ʻO ka maikaʻi o ka ʻōnaehana hydraulic ponoʻī ʻo ia ka hōʻoia ʻana i ka hana hilinaʻi o ka valve i ka koho maikaʻi loa, akā ʻoi aku ka nui o ka aila kiʻekiʻe, e like me ka mālama pono ʻole, e kū pinepine ka leakage aila.ʻO nā ʻāpana ʻōnaehana hydraulic e like me nā servo valves, nā kānana, nā pipeline kiʻekiʻe-pressure, e like me ke kumukūʻai, nā koina mālama kiʻekiʻe.

ʻO ka mea hana uila: ʻokoʻa loa ka mea hana uila mai ka mea hoʻokele pneumatic a me ka mea hoʻokele hydraulic, ʻaʻole loaʻa ka mea hoʻokele uila mai ka hoʻopaʻa ʻana o ka air compressor a me ke kahua hydraulic, pono wale ke kiʻi i ka mana a me ka hōʻailona e hoʻokele i ka ʻōnaehana bypass.Ke hoʻohālikelike ʻia me ka ʻōnaehana pneumatic a me ka ʻōnaehana hydraulic, paʻa ka mea hoʻokele uila, maʻalahi e hoʻokomo, a hoʻemi nui ʻia ka hana mālama.
