Hāʻule pinepine nā hana ʻino o Volvo excavator i nā ʻāpana aʻe:
1. Pūnaehana ʻenekini
- Paʻakikī ka hoʻomaka ʻana / hoʻopaʻa ʻana i ka manawa: Ma muli paha o kahi mea ʻike camshaft hewa (e laʻa, ka hoʻokomo ʻana o ka wai a i ʻole ka oxidation i loko o ka mea hoʻohui), nā pilikia kaapuni hoʻomaka (ʻaʻohe pane mai ke kaʻa hoʻomaka, ka mana kī ʻokoʻa ʻole), a i ʻole ka lawa ʻole o ka lawe ʻana i ka wahie diesel (nā kānana wahie i hoʻopaʻa ʻia, ʻino ka hoʻoheheʻe wahie atomization).
- Pau ka mana: Hōʻike ʻia e ka hana ʻeli nāwaliwali a me ka uahi hoʻopau nui. ʻO nā kumu kūpono e pili ana i nā mea hoʻoheheʻe wahie ʻeleʻele, kahi kānana ea paʻa, a i ʻole ka lole ʻenekini i loko (e laʻa, ka ʻā ʻana o ka aila).
- ʻEnekini wela loa: ʻO nā kumu maʻamau ka leak radiator, hāʻule ʻole ka pauma wai, a i ʻole nā poloka i ka ʻōnaehana hoʻomaha.
2. Pūnaehana Hydraulic
- Nā neʻe lohi / nawaliwali: Hiki i kēia ke hopena ma muli o ka ʻaʻahu ʻana o ka paila hydraulic, ka leaka ʻana o ka valve control (distribution valve), a i ʻole nā sila aila kahiko i loko o ka paipu waena.
- Nā pilikia huakaʻi: ʻO ka hele nawaliwali ma kekahi ʻaoʻao a i ʻole ka neʻe ʻana e pili ana i nā pilikia me ka kaʻa huakaʻi, ka haʻalulu o ke ala, a i ʻole nā hana ʻino o ka valve hydraulic.
- ʻAila Leak: Loaʻa pinepine ma muli o nā sila ʻaila cylinder kahiko a i ʻole nā laina paipu i poino.
3. Pūnaehana Uila
- ʻAʻohe hoʻomaka: E nānā i nā fuse, relays, a me nā pili i ka ECU (Electronic Control Unit) no ka hemo.
- Hōʻike ʻike ʻole ʻia: Ma muli paha o ka volta paʻa ʻole a i ʻole ka hemahema o ka sensor.
4. Nā hewa maʻamau ʻē aʻe
- ʻAila haʻahaʻa haʻahaʻa: E nānā i ka pae ʻaila, kānana aila, a me ka ʻaila pauma.
- Nā kānana i hoʻopaʻa ʻia: ʻO nā poloka i ka ea a i ʻole nā kānana aila e alakaʻi i ka emi ʻana o ka hana mīkini.
- Ke kū nei ma lalo o ka hoʻouka ʻana: Hiki ke kumu i kēia ma muli o ka hewa ʻole o ka ECU, solenoid valve failure, a i ʻole ka wahie diesel maikaʻi ʻole.
Nā Manaʻo
Manaʻo ʻia e hoʻohana i nā mea hana diagnostic e heluhelu ai i nā code hewa (e laʻa, ma o ka ʻōnaehana VECU) e kōkua i ka hoʻoponopono pilikia. Eia hou, e hoʻololi mau i nā ʻāpana hoʻopau (e like me nā kānana a me nā sila aila) e hōʻemi i nā haki. No nā pilikia paʻakikī, e ʻoluʻolu e hahai i kā mākou kaila kūhelu no nā mea hou a i ʻole e nīnau i kahi ʻenehana loea kūpono.
No ke kuhikuhi wale.
