No ke aha i hoʻopau ʻia ai ka Crankshaft Diesel Generator

I ka hoʻohana ʻana o mīkini hana diesel , ua ablated ka crankshaft sliding bearing, i ʻike mau ʻia ʻo "ke ahi ahi".ʻO ke kumu nui o kēia hāʻule ʻana, ʻo ia ke ʻano nui o ka ukana mīkini a me ka ukana wela o ka mīkini diesel, a ʻaʻole lawa ka ʻaila, ʻaʻole hiki ke hoʻokumu ʻia kahi kiʻi ʻaila lubricating maikaʻi ma waena o ka crankshaft journal a me ka bearing bush, ka hopena pololei. ka ʻaʻa ʻana ma waena o ka puʻupuʻu crankshaft a me ke kumu lāʻau.

1. Nā kumu kiko'ī o ka wehe ʻana o ka crankshaft

(1) maikaʻi ʻole ka ʻaila

a.ʻAʻole maikaʻi ka maikaʻi o ka ʻaila ʻenekini;ka nui o ka lepo i hui 'ia i loko o ka mīkini aila i ka wā lō'ihi ho'ohana, a me ka aila engine oxidized a deteriorated ma muli o ke kiʻekiʻe hana wela o ka diesel engine.

b.Aia ka wai i hui ʻia i loko o ka ʻaila ʻenekini.ʻO nā māwae i loko o ka ʻaʻahu wai a i ʻole ka ʻaʻahu wai he pohū, e ʻae ana i ka wai anuanu e komo i loko o ka ʻaila ʻenekini.

c.ʻOi aku ka lahilahi o ka ʻaila ʻenekini.Ma muli o ka hoʻohana ʻana o kekahi mau ʻenekini wahie hoʻoheheʻe ʻia i ka lubrication kaomi, i ka manawa e hoʻopaʻa ʻia ai ka pauma wahie a me ka ʻaila ʻaila e hoʻopau ʻia, komo ka ʻaila diesel i ka ʻaila hinu e hoʻoheheʻe a hoʻohaʻahaʻa i ka ʻaila lubricating engine diesel.

(2) ʻAʻole lawa ka nui o ka aila a me ke kaomi ʻaila haʻahaʻa

a.ʻAʻole lawa ka nui o ka aila.ʻO ka hiki ʻole ke hoʻohui i ka ʻaila nui e like me ka mana i ʻōlelo ʻia e hopena i ka lawa ʻole o ka holo ʻana o ka aila lubricating o ka ʻenekini diesel, a ʻaʻole hiki ke hōʻoia ʻia ke kūkulu ʻia ʻana o kahi kiʻi ʻaila lubricating.

b.He haʻahaʻa ke kaomi ʻaila.Ma muli o ke kaomi ʻaila haʻahaʻa, ʻaʻohe kiʻi ʻaila lubricating i hana ʻia ma waena o ka crankshaft journal a me ka lāʻau bearing.

c.Ma muli o ka hoʻomaʻemaʻe maikaʻi ʻole o ka ʻaila ʻenekini, ua ālai ʻia ke ala ʻaila lubricating a i ʻole ka lua aila, a i ʻole lawa ʻole a lawa ʻole paha ka aila ʻenekini ma waena o ka crankshaft journal a me ka bearing bush.

(3) He nui a liʻiliʻi paha ka ʻokoʻa ma waena o ka crankshaft journal a me ka lāʻau hili.

a.ʻO ka hoʻomaʻemaʻe ma waena o ka puke pai crankshaft a me ka lāʻau bearing he nui loa ia e hoʻohaʻahaʻa i ke kaomi aila a ʻaʻole hiki ke hana i kahi kiʻi ʻaila lubricating lawa.

b.He liʻiliʻi loa ka ʻokoʻa ma waena o ka puke pai o ka crankshaft a me ke kumu lāʻau, no laila ʻaʻole lawa ka mānoanoa o ka ʻaila hinu a i ʻole ke kiʻi ʻaila lubricating ma waena o ka nūpepa crankshaft a me ka lāʻau bearing.

c.Ke neʻe axially ke kumu lāʻau (camshaft bushing).Ma muli o ka neʻe ʻana o ka axial o ka lāʻau bearing (camshaft bushing), ua luku ʻia ka hoʻokumu ʻana o ke keʻena kaomi aila, ʻaʻole hiki ke hana ʻia ke kaomi ʻaila, a ʻaʻole hiki ke hana ʻia ke kiʻi ʻaila lubricating.

(4) ʻAʻole ʻae ʻia nā ana geometric o ka crankshaft a i ʻole cylinder block.

A. ʻO ka holo ʻana o ka radial crankshaft (crankshaft bending) he nui loa, no laila ʻaʻole liʻiliʻi a ʻaʻohe wahi ākea ka ʻokoʻa ma waena o ka puke pai a me ka lāʻau, a ʻaʻole lawa ka mānoanoa o ke kiʻi ʻaila lubricating a ʻaʻohe kiʻi ʻaila lubricating.

B. Uneven kihi o ka crankshaft hoʻohui koʻokoʻo puke pai a me uneven anles o crankshaft hoʻohui koʻokoʻo puke moʻolelo o multi-cylinder diesel engines e hana i ka āwangawa ma waena o ka connecting rod puke pai a me ka bearing bush liʻiliʻi loa aʻaʻohe puka, a me ka mānoanoa o ka lubricating kiʻiʻoniʻoni. lawa ʻole a ʻaʻohe kiʻi ʻaila lubricating.

C. He ilihune loa ka coaxiality o ka puka lawe nui o ka poloka cylinder, ka hopena i ka liʻiliʻi a i ʻole ka ʻokoʻa ma waena o ka puke moʻolelo nui a me ka lāʻau, ʻaʻole lawa ka mānoanoa lubricating aila kiʻiʻoniʻoni a ʻaʻohe kiʻi ʻaila lubricating.

D.The verticality o ka cylinder puka a me ka nui hali puka mea ilihune, kumu o ka hoʻohui koʻokoʻo puke moʻolelo a me ka kumu kumu kumu puke puke palapala hoʻomaʻemaʻe e liʻiliʻi a ʻaʻole hoʻomaʻemaʻe ʻole, lawa ʻole lubricating aila kiʻiʻoniʻoni mānoanoa a ʻaʻohe kiʻi ʻaila lubricating.

(5) ʻAʻole ʻae ʻia ka pololei o ke kaulike o ka crankshaft, flywheel a me ka clutch.

I ka wā ʻaʻole i hoʻomanawanui ka pololei o ke kaulike ʻana, e hoʻonui ka wikiwiki o ka crankshaft i ka ikaika inertial, kahi e hōʻino ai i ka wehe ʻana ma waena o ka crankshaft journal a me ke kumu lāʻau.I nā hihia koʻikoʻi, e hoʻopili pololei ka puke pai a me ka lāʻau i ka crankshaft a hoʻopau i ka crankshaft.

(6) Ka mālama pono ʻole.

Ma hope o ka holo ʻana o ka ʻenekini diesel no kekahi manawa, inā ʻaʻole mālama ʻia ka mālama kūpono i ka manawa, e hoʻopau ʻia ka pahū aila e hoʻopaʻa ai i ka valve, ka ʻaila a me nā ʻāpana ʻē aʻe e ʻaʻahu, hāʻule a deform.Hoʻopaʻa ʻia ka mea kānana o ka kānana aila e ka lepo ʻaila a me ka sludge, kahi e hoʻemi ai i ke kaomi ʻaila a hoʻopau i ka crankshaft.

Inā makemake ʻoe i nā mea hoʻoheheʻe diesel hāmau , e leka uila pololei iā mākou: dingbo@dieselgeneratortech.com.
