ʻO ka'ōnaehana hydraulic o ka hydraulic excavator piha heʻehā mau mea nui: nā mea mana, nā mea hoʻokō, nā mea mana a me nā mea kōkua.
ʻO ka mea mana ka hapa nui o ka pauma piston variable, nona ka hana e hoʻohuli i ka ikehu mechanical o ka mīkini i ka ikehu kaomi wai, a ʻo ka mea maʻamau ʻaʻole lawa ka ʻaila ʻaila a hoʻemi ʻia ke kahe. Inā hele mālie kēia ʻano, a ʻoi aku ka kiʻekiʻe o ka mahana i ʻike ʻia, no ka nui o ka lole a me ka waimaka o ka paila hydraulic; inā hikiwawe kēia ʻano, ʻo ka hapa nui ma muli o ka plunger ʻaʻole i hana; inā maʻamau ke kaomi, hoʻemi koke ke kahe, ma muli o ke ʻano ʻano loli i paʻa i kahi kūlana kahe liʻiliʻi.
Hoʻokomo ʻia nā mea hana i nā cylinders hydraulic a me nā kaʻa hydraulic, nona ka hana e hoʻohuli i ke kaomi o ka wai i loko o ka ikehu mechanical, ʻo kahi hanana maʻamau ka lohi o ka hana a ʻaʻohe hana. Inā hoʻokūpaʻa ʻia ka pauma a me ka valve i ka hala ʻole, ʻo ke kumu o ka hana lohi o ka mea hoʻokalakupua ma muli o kona ʻaʻahu nui a me ka waimaka; inā hana maʻamau ka pāpaʻi, ʻo ka hana lohi o ka mea hoʻokalakupua he hewa paha ka valve e hoʻomalu ana i ka mea hana, e like me ka paʻa ʻole o ka valve, ʻaʻole i pani paʻa ʻia ka pahu hoʻomaha a nāwaliwali paha ka ikaika o ka puna. a me ke kāleka. No ka mea, ʻaʻole e ʻokoʻa loa ke ʻano o ka ʻaʻahu a me ka waimaka o kēlā me kēia mea hoʻokō, e like me nā kumu ʻē aʻe, pono ia he helu o nā mea hoʻokō o ka hana i ka manawa like e lohi koke; inā ʻike ʻia ʻaʻole hewa ka pauma a me ka valve, ʻaʻohe hana o kahi mea hoʻokō, ʻo ia ka hapa nui ma muli o kona hoʻopaʻa ʻana i loko.
Loaʻa nā mea hoʻomalu i nā ʻano valve like ʻole, e like me nā valve pilote, nā ala kuhikuhi multi-way valves, nā valves palekana nui, nā valves hoʻomaha a me nā valve throttle one-way, etc. , paʻa nui, paʻa a me ka elasticity punawai nāwaliwali a me ka leaka o loko a me waho.
ʻO nā mea kōkua nui ka pahu aila, paipu aila, radiator, kānana a me ka accumulator, a me nā mea ʻē aʻe.. ʻO ka hana o ka radiator e puʻunaue i ka wela i hana ʻia e ka ʻōnaehana hydraulic i ka lewa, a ʻo kāna mau hāʻule maʻamau ʻo ia ka leakage aila, ka hoʻokuʻu ʻana o ka wela. etc. ʻO ka hana o ka kānana ke kānana i nā mea haumia i hui pū ʻia i loko o ka ʻaila hydraulic, a ʻo kāna mau hemahema maʻamau e pili ana i ka clogging o ka pale. ʻO ka hana a ka accumulator ka hoʻopaʻa ʻana a me ka mālama ʻana i ke kaomi ʻaila a mālama i kekahi nui o ka ikehu e hōʻoia i ka hana maʻemaʻe a i ka wā e hana ʻole ai ka mīkini, hiki ke hoʻohaʻahaʻa ʻia ka mea hana i ka lepo, a ʻo kāna mau hemahema maʻamau ka mālama ʻana i ka ikehu. hopena, ʻaʻole hiki ke hoʻopau i nā hana i luna. ʻOi aku ka maʻalahi o nā ʻāpana kōkua o ka hanana hemahema, maʻalahi ke ʻike.
