Nā kumu o ka pōʻino i nā lāʻau hoʻoheheʻe o nā mea hana

He aha ke kumu e pōʻino ai ka lawe ʻana i nā lāʻau o ka generator set?Pane ka mea hana mīkini hana Diesel iā ʻoe.

1. I ka wā o ka hana maʻamau o ka mīkini diesel, aia kahi āpau ma waena o ka crankshaft journal a me ka bearing bush a aia kahi kiʻi ʻaila e hana ai i ka lubrication wai.Ma kēia ʻano, liʻiliʻi ka poho friction, a liʻiliʻi hoʻi ka wela i hana ʻia e ka friction.Laweʻia ka wela e kaʻaila, aʻo ka mahana hana ma keʻano maʻamau.

2. Ina o ka laau hali o uila uila pili pololei me ka puke pai e hana i kahi mokuʻāina maloʻo maloʻo, e hoʻonui nui ʻia ka hoʻohana ʻana i ka mana frictional, a e hana ʻia ka nui o ka wela frictional a hoʻopau ʻia e ka lāʻau bearing.Eia naʻe, ʻaʻole nui ka wela i lawe ʻia e ka ʻaila, e hōʻiliʻili ka wela i loko o ka ʻili, a piʻi mau ka mahana.I ka wā e hoʻoheheʻe ai ka ʻili o ka pūpū huila ma ka ʻili o ka pūpū, e hoʻomaka ka heheʻe a hiki i ke ahi, e hoʻopau ʻole ai ka hana ʻana o ka mīkini diesel.

3. He kiʻekiʻe a haʻahaʻa paha ka mahana o ka aila

A. Ke haʻahaʻa loa ka mahana o ka aila, ʻoi aku ka kiʻekiʻe o ka viscosity o ka ʻaila lubricating a ʻilihune ka wai.ʻOi aku i ka mokuʻāina hoʻomaka anu, he liʻiliʻi ka nui o ka aila e komo ana i ka crankshaft, kahi maʻalahi e hana i ka lāʻau bearing a me ka crankshaft journal e hoʻopili pololei, a wikiwiki i ka ʻaʻahu a me ka pōʻino o ka bearing.

B. Ke kiʻekiʻe loa ka mahana o ka aila, e haʻahaʻa loa ka viscosity o ka ʻaila lubricating, a e nāwaliwali ka ikaika o ka ʻaila kiʻiʻoniʻoni, e hopena i ka thinning o ka mānoanoa o ka aila kiʻiʻoniʻoni, a he mea maʻalahi hoʻi ke kumu mua. ʻaʻahu a me ka pōʻino o ka lāʻau bearing.I mea e hoʻonui piha ai i ke ola lawelawe o ka bearing, pono e mālama ʻia ka mahana maʻamau i loko o ka laulā o 95 ~ 105 ℃.ʻOiaʻiʻo, ua loli paha kēia ʻano ma muli o nā ʻano like ʻole o ka mīkini diesel.

C. ʻAʻole maikaʻi ka maikaʻi o ka ʻaila lubricating.Ua hoʻohana ka generator set i ka aila lubricating haʻahaʻa a i ʻole ka aila lubricating hoʻopunipuni i ka wā e hoʻohana ai.Inā ʻaʻole i kūpono ka maikaʻi o ka aila lubricating i nā koi o ka mea hana ʻenekini diesel, e hana pū ai ka mīkini diesel e hana i nā hemahema o ka nahele.

4. ʻAʻole ʻae ʻia ka hui ʻana o ka lawe ʻana

A. No ka hoʻomaikaʻi ʻana i ke kūlana lubrication o nā bearings nui o ka mīkini diesel e kū nei a pale i ka pōʻino o ke ahi, pono e mālama pono ʻia ka ʻae ʻana ma waena o ka bearing a me ka crankshaft journal e like me nā koi o ka manual engine operation diesel.

B. I ka wā e pani ai i ka lāʻau bearing, e nānā i ka poepoe a me ka cylindricity o ka puke pai crankshaft.Inā ʻoi aku ia ma mua o ka palena, pono e hoʻopaʻa ʻia e pale i ka hōʻemi ʻana i ka wahi pili o ka puke pai a me ka lāʻau ulu a hoʻonui i ke kaomi ma kēlā me kēia ʻāpana.

C. Eia hou, pono e hoomaluia ka axial clearance o ka crankshaft, a ina he nui ka lole, pono e hooponopono ia i ka manawa.

5. Hoʻohaʻahaʻa ʻia ka lubricant

A. ʻO ka mea maʻamau, i ka wā o ka hoʻohana ʻana i ka aila lubricating, ma muli o ka ʻaʻahu ʻana o nā ʻenekini diesel cylinder liners a me nā apo piston, a me nā hoʻololi ʻana i nā puka puka piston apo a me nā kūlana wehe, ke hoʻomau nei ka wela kiʻekiʻe a me ke kiʻekiʻe kiʻekiʻe. e hoonui.ʻAʻole kēia wale nō ka mea e piʻi ai ka mahana o ka ʻaila lubricating, akā e hoʻolalelale i ka oxidation a me ka polymerization o ka ʻaila lubricating.

B. I ka manawa like, hui pū ʻia me ka hui ʻana o nā huahana hoʻoheheʻe diesel, ka hui ʻana o ka lepo o waho, nā ʻōpala metala, a me ka hoʻohana ʻana i nā mea hoʻohui i loko o ka ʻaila lubricating, ʻoi aku ka wikiwiki a me ka deterioration o ka ʻaila lubricating.ʻAʻole kēia e hoʻonui wale i ka ʻaʻahu a me ka corrosion o ka friction pai ma ka ʻāpana lubricating o ka mīkini diesel, akā ke kumu nui o ke ahi o ka bearing.

6. Hapai ka pilikia maikaʻi

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, e hoʻopiʻi ʻia ka pau ʻana o ka lāʻau.No laila, ke kūʻai aku nei ʻoe i ka generator diesel, pono ʻoe e hoʻolohe i ka maikaʻi o ka mīkini diesel.

7. Nui loa ka haʻalulu i ka wā e hana ai ka ʻenekini diesel

A. Ma muli o ka pōʻino o ka haʻalulu a i ʻole nā ​​kumu ʻē aʻe, haʻalulu nui ka mīkini diesel i ka wā e hana ai.

B. Ua hiki no hoi ke poino ka mea hoohuoi o ka crankshaft engine diesel, no ka mea, e haalulu nui ai ka crankshaft engine diesel;ma hope o ka lōʻihi o ka hana ʻana, hiki iā ia ke hoʻokuʻu i ka ʻili o ka ʻili, ka hopena i ke ahi a i ʻole ka paheʻe ʻana o ka nahele.

I ka pōkole, ʻaʻole hiki iā mākou ke mālama wale i ke kumukūʻai huahana, he mea nui hoʻi ka maikaʻi o ka huahana, a laila koʻikoʻi ka mālama mau ʻana ma hope o ka hoʻohana ʻana. nā mea hana diesel .
