ʻIke kumu o 500KVA Diesel Generator Abnormal Bush Burning Faults

ʻO ka mīkini Diesel kahi ʻāpana nui o 500KVA diesel generator, he nui nā kumu e hoʻopau ai i ka lāʻau ʻenekini diesel.ʻO ka nele o ka ʻaila ʻenekini ma ka ʻenekini diesel kekahi o nā kumu nui no ka puhi ʻana o ka ʻenekini diesel Bush.Ke holo nei ka mīkini diesel me ka ʻaila ʻole, pono ia e puhi i ka lāʻau, akā hiki ke puhi ʻia ka lāʻau inā ʻaʻole nele ka aila.

I kēia lā, mana Dingbo, a mea hana hana diesel , ua kālailai i nā kumu o ka ʻā ʻana o ka lāʻau maʻamau o 500KVA diesel generator.Manaʻolana ua kōkua kēia ʻatikala iā ʻoe.

1. Ka nānā 'ana i ke kumu

Ma ke kaʻina hana maʻamau o ka ʻenekini diesel, aia kahi ʻokoʻa ma waena o ka crankshaft journal a me ke kumu lāʻau a me ka ʻaila kiʻiʻoniʻoni e hana ai i ka lubrication wai.Ma kēiaʻano, liʻiliʻi ka poho o ka friction, liʻiliʻi ka wela i hanaʻia e ka friction, laweʻia ka wela e kaʻaila, a he mea maʻamau ka mahana hana.Inā pili pololei ka lāʻau hili me ka puke pai e hana i kahi mokuʻāina maloʻo maloʻo, e piʻi nui ka hoʻohana ʻana i ka mana friction, a e hoʻoulu ʻia ka nui o ka wela friction, e hoʻopau ʻia e ka lāʻau bearing, ʻoiai ka wela. lawe ʻia e ka ʻaila ʻaʻole nui.E hōʻiliʻili ka wela i loko o ka nahele bearing a piʻi mau ka mahana.Ke ʻoi aku ka mahana ma mua o ka helu heheʻe huila ma ka ʻili o ka nahele bearing, e hoʻomaka ka heheʻe o ka ʻili o ka nahele a hiki i ka wā e pau ai ke ahi, e hopena i ka pau ʻole o ka mīkini diesel.

2. Nā kumu pili i ka hāʻule

A. Kiʻekiʻe a haʻahaʻa paha ka wela o ka aila

Ke haʻahaʻa loa ka mahana o ka aila, ʻoi aku ka kiʻekiʻe o ka viscosity o ka ʻaila lubricating a maikaʻi ʻole ka wai.ʻOi aku i ka wā hoʻomaka anuanu, ʻoi aku ka liʻiliʻi o ka aila e komo ana i ka crankshaft, maʻalahi e hana i ka lāʻau bearing e pili pono me ka crankshaft journal a hoʻolōʻihi i ka lole a me ka pōʻino o ka bearing.Ke kiʻekiʻe loa ka mahana o ka aila, ua haʻahaʻa loa ka viscosity o ka ʻaila lubricating a nāwaliwali ka ikaika o ka ʻaila kiʻiʻoniʻoni, ka hopena i ka lahilahi o ka mānoanoa o ka ʻaila hinu, a he mea maʻalahi hoʻi e hana i ka ʻaʻahu mua a me ka pōʻino o ka ʻaila. hali laau.Manaʻo nui ʻia ʻo ka wela kiʻekiʻe o ka ʻaila lubricating engine diesel he 130 ℃.Eia nō naʻe, i mea e hoʻonui piha ai i ke ola lawelawe o ka bearing, pono e mālama ʻia ka mahana maʻamau i ka laulā o 95 ~ 105 ℃.

B. Thermal oxidation paʻa o lubricating aila

He hopena koʻikoʻi ka pale ʻana o ka oxidation thermal o ka ʻaila lubricating i ka lubrication ma waena o ka crankshaft a me ka bearing.Inā hoʻohana ʻia ʻelua ʻaila lubricating like ʻole ma ka prototype like a hana mau ma lalo o ke kūlana hana like, ʻokoʻa nā hopena i ana ʻia.

C.Improper lawe ana hui hoʻomaʻemaʻe

I mea e hoʻomaikaʻi ai i ke kūlana lubrication o ka pahu nui o ka mīkini diesel e kū nei a pale i ka puhi ʻana, pono e hoʻomalu ʻia ka ʻae ʻana ma waena o ka bearing a me ka crankshaft journal e like me nā koi o ka manual engine engine diesel.I ka hoʻololi ʻana i ka lāʻau bearing, e nānā i ka pōʻai a me ka cylindricity o ka crankshaft journal.Inā ʻoi aku ia ma mua o ka palena, pono e hoʻomaʻemaʻe ʻia i mea e pale ʻole ai i ka hōʻemi ʻana i ka wahi pili o ka puke pai a me ka ulu ʻana a me ka hoʻonui ʻana i ke kaomi no kēlā me kēia ʻāpana.Eia hou, e hoomaluia ka axial clearance o ka crankshaft.Inā ʻoi aku ka ʻaʻahu ma mua o ka palena, e hoʻoponopono ʻia i ka manawa.

D. ʻO ka ʻaila lubricating deterioration

ʻO ka ʻōlelo maʻamau, i ka wā o ka hoʻohana ʻana i ka aila lubricating, ma muli o ka ʻaʻahu ʻana o ka mīkini diesel cylinder liner a me ke apo piston, a me ka hoʻololi ʻana o ke apo piston wehe ʻana a me ke kūlana wehe, ke kiʻekiʻe-mehana a me ke kiʻekiʻe-pressure combustible hui e kahe ana i loko o ka. Ke piʻi nei ka crankcase, ʻaʻole ia e hoʻonui wale i ka mahana o ka ʻaila lubricating, akā wikiwiki hoʻi i ka oxidation a me ka polymerization o ka ʻaila lubricating.I ka manawa like, ma muli o ka hui ʻana o nā huahana hoʻoheheʻe diesel, ka hui ʻana o ka lepo o waho a me nā ʻōpala metala, a me ka hoʻohana ʻana i nā mea hoʻohui i ka ʻaila lubricating, ʻoi aku ka wikiwiki o ka deterioration a me ka wikiwiki o ka ʻaila lubricating.ʻAʻole kēia e hoʻonui wale i ka lole a me ka corrosion o ka friction pair o ka ʻāpana lubricating o ka mīkini diesel, akā ʻo ke kumu nui hoʻi no ka pau ʻana o ke ahi.

E. He maikaʻi ʻole ka ʻaila lubricating

Hoʻohana ka ʻenekini diesel i ka aila lubricating haʻahaʻa a i ʻole ka aila lubricating kiʻekiʻe hoʻopunipuni i ke kaʻina hana.Inā ʻaʻole i hoʻokō ka pae maikaʻi o ka aila lubricating i nā koi o ka mea hana ʻenekini diesel, e alakaʻi pū ʻia nō hoʻi ia i ka hoʻopau ʻana o Bush i ka mīkini diesel.

F. Pilikia maikaʻi o ka ulu ʻana i ka lāʻau

Inā hoʻohana ʻia nā mea haʻahaʻa haʻahaʻa, ʻaʻole lawa ka pale wela kiʻekiʻe a me ka hiki ʻana o ka bearing bush.ʻOiai inā he mea maʻamau ke kaomi ʻaila a lawa ka nui o ka aila, ʻo ke kumu o ke ahi ʻana o Bush.

G. He nui loa ka haʻalulu o ka mīkini diesel i ka wā e hana ai

ʻO ka haʻalulu o ka mīkini diesel i ka wā o ka hana he nui loa ma muli o ka pōʻino o ka haʻalulu a i ʻole nā ​​kumu ʻē aʻe;Ua poino paha ka mea damping o ka crankshaft engine diesel, i mea e haalulu nui ai ka crankshaft engine diesel;Ma hope o ka hana lōʻihi, hiki ke wehe ʻia ka lāʻau hili, ka hopena i ke ahi ʻana a i ʻole ka hoʻoheheʻe ʻana.

H. He kiʻekiʻe loa ka mahana o ka mīkini diesel

Ma muli o ka hemahema o ka ʻōnaehana hoʻoluʻu a i ʻole nā ​​​​kumu ʻē aʻe, ʻoi aku ka kiʻekiʻe o ka wela a me ka ʻaila o ka mīkini diesel, e hopena i ka pau ʻana o ka Bush ʻana o ka mīkini diesel ma hope o ka hana lōʻihi.

3. Hoʻomalu no ka hoʻohana ʻana i 500kva diesel mīkini hana wāwahie

a.Ka mālama mau: hoʻomaʻemaʻe i nā ʻāpana, dredge i ke ala ʻaila, hoʻohui a hoʻololi paha i ka aila i ka manawa e pale ai i ka ʻaila mai ka ʻelemakule a i ʻole ka lepo a paʻa i ke ala ʻaila.

b.E koho i ka aila lubricating e kūpono ana i nā koi o ka mea hana mīkini diesel a mālama pono e like me ka mea e pono ai.

c.Ma mua o ka hoʻomaka ʻana i ka mīkini diesel, e nānā pono i ka nui o ka aila lubricating.Inā lawa ʻole, e hoʻohui e like me nā lula.

d.I ka hoʻomaka ʻana o ke anuanu, e hana mua me ka wikiwiki ʻole ma lalo o ka haʻahaʻa ʻole no 3 ~ 5 mau minuke, a laila hoʻololi mālie i ka hana wikiwiki a kaumaha paha.

e.ʻAʻole pāpā ʻia ka hana ʻana i ka mīkini hana diesel no ka manawa lōʻihi ma lalo o ka overload e pale i ka wikiwiki wikiwiki;Inā ʻike ʻia ua ʻā ke kukui ʻaila kaomi, e ʻimi i ke kumu a mālama pono iā ia ma mua o ka hoʻomau ʻana i ka hana.

f.I ka wā mālama, e nānā pono i nā ʻāpana āpau o ka ʻōnaehana lubrication.ʻAʻole hiki ke hoʻololi i nā ʻāpana koʻikoʻi (e laʻa, ʻaʻole hiki ke hoʻololi i ka uea hao i ka cotter pin, etc.).I ka hui ʻana, e hoʻohana i ka ʻaila lubricating maʻemaʻe.

g.I ka hoʻololi ʻana i kahi lāʻau bearing hou, e nānā i ka lōʻihi o ka lāʻau bearing.He pōkole loa ka lāʻau i hiki ke hōʻoia i kona kūpono kūpono me ka puke pai a me ka hoʻopau wela maikaʻi;Ke lōʻihi loa ka lāʻau bearing, e deformed ka interface, kahi e alakaʻi ai i ka gnawing shaft.

h.E nānā mau i ka hopena ʻoluʻolu o ka ʻōnaehana hoʻoluʻu ʻenekini diesel, e hoʻolohe i ka hoʻohui ʻana i ka mea hoʻomaha a hoʻopaʻa a hoʻololi paha i ke kāʻei peʻa i ka manawa e hōʻoia ai i ka maikaʻi mau o ka ʻōnaehana.
