Aloha kākou, ʻo wau ʻo Fane Zhao mai Xuzhou Kavo.
Ua ʻike ka nui o nā mea hana excavator kahiko i ka haʻahaʻa haʻahaʻa o ka hāʻule ʻana o ka mana o ka excavator, akā ʻaʻole hiki ke ʻalo ʻia ke pani ʻana. Ke hana nei koʻu ʻanakala ma ke ʻano he excavator operator no 18 mau makahiki, a ua haʻi mai ʻo ia iaʻu ʻo ka hapa nui o nā ʻāpana o ka excavator aia i loko o nā ʻōnaehana hydraulic a me ka mana, ʻoiai ʻo ka manawa e haki ai ka ECU (Electronic Control Unit) he liʻiliʻi. Eia nō naʻe, makemake mau kekahi mau hoaaloha e ʻike i nā pilikia maʻamau e hiki mai ana me ka mana mana (ECU). I kēia lā, e kūkākūkā pū kākou i kēia kumuhana, a e ʻoluʻolu e kuhikuhi i nā hemahema no ke kūkākūkā hou aku.
ʻO ka mana o ka excavator (i kapa ʻia ʻo ECU, ka "lolo" o ka mīkini holoʻokoʻa) ʻo ia ke kikowaena nerve o ka ʻōnaehana uila. ʻO ka nui o kona pōʻino e pili ana i nā kumu kaiapuni, nā hewa hana, a me nā hewa kaapuni, ma waena o ka overload circuit, ka komo ʻana o ka wai a me ka pulu, a me ka uila paʻa ʻole ke kumu maʻamau.
Manaʻo 1: Poino i hana ʻia e nā hewa hana pili kaapuni (pinepine) ʻO kekahi poʻe hana, no ka hilinaʻi nui, hiki ke hana hewa e like me ka hoʻohuli ʻana i nā pou maikaʻi a me nā pole maikaʻi ʻole i ka wā e lele ai-hoʻomaka i ka pākaukau i kahi pilikia, a i ʻole e hoʻohana ana i kahi lako mana me ka uila like ʻole (e like me ka hāʻawi ʻana i ka mana 24V i kahi ʻōnaehana 12V). Hiki i kēia ke hoʻopau koke i nā ʻāpana uila i loko o ka ECU, ʻo ia ka hana ʻoi loa e hoʻolilo i ka ECU i mea ʻole. Eia hou, hiki i nā hoʻololi kaapuni ʻae ʻole (e like me ke kau ʻana i nā kukui mana kiʻekiʻe a i ʻole nā mea hoʻomehana) hiki ke hoʻonui i ka kaapuni, a laila e hoʻopau i ka module lako mana o ka ECU.
ʻO ke kāʻei uwea a me ke kaapuni pōkole ʻO nā mea ʻeli e haʻalulu ikaika i ka wā e hana ai. Inā ʻaʻole i hoʻopaʻa paʻa ʻia ke kaula uwea, e ʻānai ia i nā ʻāpana o ke kino mīkini, nā alahele, a me nā mea ʻē aʻe, e alakaʻi ana i ka pōʻino insulation a me nā kaapuni pōkole. ʻO ka hoʻihoʻi ʻana i kēia manawa e hoʻopilikia i ka ECU, e hoʻopau ai ka chip. He mea maʻamau kēia kūlana ma nā kahua kūkulu me nā ʻiliʻili he nui a me nā kūlana lepo.
Manaʻo 2: Poino i hana ʻia e nā kumu kaiapuni E like me kā mākou e ʻike ai, hoʻohana ʻia nā excavators i nā ʻano hana like ʻole, mai ka maikaʻi a i nā kūlana koʻikoʻi loa.
ʻO ke komo ʻana o ka wai a me ka pulu Hoʻokomo pinepine ʻia ka ECU i loko o ke kaʻa a i ʻole kahi pahu pale ma ke kino mīkini. Eia nō naʻe, i ka wā o ka hana ʻana i ka ua nui a i ʻole ke au ʻana i loko o ka wai, inā ʻelemakule ka ʻōpala hoʻopaʻa sila a ʻaʻole i pani paʻa ʻia ka uhi pahu pale, e komo ka wai ua i loko. Eia hou, holoi pololei i ka wahi hoʻokomo ECU me kahi pū wai kiʻekiʻe i ka wā e hoʻomaʻemaʻe ai i ka excavator e hiki ai i ka wai ke komo i loko o nā lua hoʻoheheʻe wela, e hopena i ka ʻino a me nā pōkole pōkole o ka papa kaapuni.
Hōʻike wela kiʻekiʻe I ka wā o nā hana waho i ke kauwela, hiki i ka mahana o ke kino mīkini ke ʻoi aku ma mua o 60 ° C. Inā loaʻa ka ECU i ka wela wela a aia i loko o kahi ʻano wela kiʻekiʻe no ka manawa lōʻihi, ʻo nā mea i loko e like me nā capacitors a me nā resistors e hoʻolalelale i ka ʻelemakule, a laila e alakaʻi i nā malfunctions.
Hōʻike 3: Poino i hana ʻia e nā kumu ikaika o ka hana ʻO ka hana overloaded lōʻihi
I ka ʻeli ʻana i nā pōhaku paʻakikī a i ʻole ka hāpai ʻana i nā mea kaumaha ma mua o ka haʻahaʻa i helu ʻia, e hana ka ʻenekini a me ka ʻōnaehana hydraulic ma lalo o nā kūlana koʻikoʻi. Pono ka ECU e hoʻopuka mau i nā kauoha haʻahaʻa kiʻekiʻe, hiki ke maʻalahi i ka wela a me ka pōʻino i nā ʻāpana o loko.
Huipuehu Ma nā wahi lepo lepo e like me nā mines a me nā wao nahele, hiki i ka lepo ke komo i ka ECU, e uhi ana i ka papa kaapuni a me nā ʻāpana, e hopena i ka hoʻoheheʻe wela maikaʻi ʻole. I kēia manawa, hiki i nā ʻāpana metala i loko o ka lepo ke hana i nā kaapuni pōkole.
No laila, i ka wā e hoʻohana ai i kahi excavator, pono mākou e hana ma ke ʻano maʻamau, e hoʻolohe i ka mālama ʻana, a hana i ka nānā pinepine ʻana i nā mea hana i ka wā o ka hana overloaded e hōʻoia i ka holomua maikaʻi o nā papahana.
