Hiki i ka 40 pākēneka o kahi mea kanu meaʻai hiki ke hele i ka pau ma muli o nā koi nani o kekahi mau hale kūʻai.ʻOiai ʻaʻole ʻoluʻolu loa ka mea kanu wonky i ka nānā ʻana, loaʻa iā ia ka waiwai meaʻai like me kona ʻano like ʻole.

Hiki ke lawe ʻia nā ʻano like ʻole o ka lawe ʻana i ka pōʻino o ka ʻili, mai nā spalls i nā alanui heihei, ka ʻaʻahu ʻana mai ka lubrication pono ʻole, ka corrosion ma muli o nā kemika koʻikoʻi a i nā hōʻailona brinelling wahaheʻe i hoʻokumu ʻia e ka static vibration.ʻOiai hiki i ka pilikia o ka ʻili ke hopena i nā hōʻailona pilikia e like me ka wela nui, piʻi ka leo nui, hoʻonui i ka haʻalulu a i ʻole ka neʻe ʻana o ke kumu lāʻau nui, ʻaʻole ʻo nā hemahema o waho a pau e kuhikuhi ana i ka hoʻokō ʻana o ka mīkini kūloko.

ʻO ka corrosion kahi hanana kūlohelohe a he ʻano maʻamau o ka lawe ʻana i ka pōʻino o ka ʻili e pono ai e hoʻopaʻapaʻa ʻia e nā luna o nā mea kanu aila a me nā kinoea.He ʻumi nā ʻano ʻino mua, akā hāʻule maʻamau ka ʻaʻa ʻana i loko o ʻelua mau ʻāpana ākea - ka ʻāʻī ʻana a i ʻole ka ʻāʻī ʻana.ʻO ka mea mua he mea kaiapuni, akā hiki ke ʻike ʻia ma kekahi ʻāpana o ka bearing, e hana ana i kahi papa oxide weliweli ma muli o ka hopena kemika me kahi ʻili metala.

No ka laʻana, i ka ʻeli ʻana i waho, ʻike pinepine ʻia nā bearings i ka makū a i ʻole ka alkalinity haʻahaʻa ma muli o ko lākou pili ʻana me ka wai kai.Hiki i ka ʻino maʻemaʻe ke hopena i nā ʻeleʻele o ka ʻili, akā i nā hihia koʻikoʻi, hiki ke alakaʻi i ke kahakaha ʻana ma luna o ka ʻili o ka bearing, ka hopena o nā ʻōpala o nā mea ʻōpala e komo i ke ala heihei.No kēia kumu, ʻike pinepine ʻia ka corrosion ʻo ka ʻenemi kūlohelohe o nā bearings.

ʻAʻole makaʻu wale ka ʻino;Hiki iā ia ke hoʻololi nui i ke kālā o ka ʻoihana.Wahi a ka haʻawina IMPACT i mālama ʻia eNACE International, ka hui hoʻomalu corrosion poʻokela o ka honua, ua manaʻo ʻia he 15-35 pākēneka o ka corrosion makahiki ke mālama ʻia inā e hahai ʻia nā hana hoʻokele corrosion maikaʻi loa.Hoʻohālikelike kēia i ka mālama kālā ma waena o US $375 a me $875 biliona i kēlā me kēia makahiki ma ke kumu honua.

ʻO ka ʻenemi?

ʻAʻole hiki ke nānā ʻole i ke koʻikoʻi o nā kumukūʻai corrosion, akā pono e noʻonoʻo ʻia ke kūpaʻa ʻana me nā koi ʻē aʻe e like me ke kau ʻana i ka lōʻihi a me ka ukana.

E noʻonoʻo i kēia he laʻana.Pono ka mīkini wili e hana me ka pololei akā pono e hana i nā kūlana kala ʻole.Ma muli o ke kaiapuni koʻikoʻi o nā rigs aila a me ke kinoea, e paipai ʻia nā bearings kūpaʻa.Inā koho ka mea ʻenekinia hoʻolālā i kahi bea kūpaʻa ʻino loa i hana ʻia mai ka polyether ether ketone (PEEK), e hoʻopau kēia i ka ʻino ma kona mau ala, akā e hoʻopilikia ʻia ka pololei o ka mīkini.Ma kēia ʻano hiʻohiʻona, ʻoi aku ka maikaʻi o ke koho ʻana i ke kila kuhili ʻole me ka pōʻai ʻoi aku ka maikaʻi ʻoiai ʻoi aku ka maikaʻi.

I ka loiloi ʻana i ke kūpono a me ka maikaʻi o nā bearings, he mea nui e nānā i waho o ka aesthetic waho.ʻO ka hoʻomalu corrosion hoʻokahi wale nō koi hana, ʻaʻole ia e like me ka hana maikaʻi ʻole a i ʻole ka hopena i ka rollability kūloko o ka bearing.

ʻO ka hōʻoia ʻana i ke koho ʻana i nā mea hana kūpono ʻo ia ka hana mua - a he mea nui kēia no nā mīkini nui a me nā mea liʻiliʻi, e like me nā bearings.ʻO ka mea pōmaikaʻi, hiki i nā luna hoʻokele o waho ke kaupaona i kā lākou mau koi hoʻolālā a hiki ke koho e hakakā i ka corrosion ma ke kahua hoʻolālā.Eia nā ʻano hana hoʻomalu corrosion ʻekolu e noʻonoʻo ai:

A-Material koho

ʻO ke kila kila ka koho ʻoi loa no ka pale ʻana i ka corrosion a hoʻohana nui ʻia i loko o ka ʻoihana ʻaila a me ke kinoea.Loaʻa iā ia nā waiwai maikaʻi ʻē aʻe e like me ke kūpaʻa a me ka pale wela.ʻO 440 grade stainless steel bearings he kūpaʻa maikaʻi i nā wahi wai a hoʻohana pinepine ʻia i nā noi e like me ka ʻoihana meaʻai a me nā mea inu.Eia nō naʻe, ʻaʻole maikaʻi ke kūʻē ʻana o 440 grade stainless steel i ka wai paʻakai a me ka nui o nā kemika ikaika, no laila, no nā kaiapuni waho ʻino, hiki ke noʻonoʻo ʻia he 316 stainless steel.Eia naʻe, no ka mea, ʻaʻole hiki ke hoʻopaʻakikī ʻia ka 316 stainless steel, kūpono nā bearings 316 no nā haʻahaʻa haʻahaʻa a me nā noi wikiwiki.ʻOi aku ka maikaʻi o ko lākou pale ʻana i ka corrosion inā loaʻa ka nui o ka oxygen no laila e hoʻohana nui ʻia kēia mau bearings ma luna o ke kahawai wai, i ke kahe o ke kai a i ʻole kahi e holoi ʻia ai nā bearings ma hope o ka hoʻohaʻahaʻa ʻana i ka wai kai.

ʻO kahi koho mea ʻē aʻe he keramika.Hiki ke hā'awi aku i nā ki'eki'e ki'eki'e o ke kū'ē corrosion a ho'ohana pinepine 'ia i loko o ka wai.Pēlā nō, ʻo nā bearings plastic, me 316 stainless steel a i ʻole pōpō aniani, hāʻawi maikaʻi loa i ke kūʻē ʻana i ka corrosion.Hana pinepine ʻia kēia mai ka resin acetal (POM) akā loaʻa nā mea ʻē aʻe no nā waikawa ikaika a me nā alkali e like me PEEK, polytetrafluoroethylene (PTFE) a me polyvinylidene fluoride PVDF.E like me ka 316 papa bearings, pono e hoʻohana ʻia kēia i nā haʻahaʻa haʻahaʻa a me nā noi haʻahaʻa haʻahaʻa.

ʻO kekahi pae o ka pale kaua e kū'ē i ka corrosion, he pale pale.Hāʻawi ka Chromium a me ka nickel plating i ka pale ʻana i ka corrosion maikaʻi i nā wahi ʻino loa.Eia naʻe, e hoʻokaʻawale ʻia nā uhi mai ka bearing a pono e mālama mau.ʻAʻole kēia ka koho kūpono loa no nā noi waho.

B-Lubricants

Hāʻawi ka lubricant i kahi kiʻiʻoniʻoni lahilahi ma waena o nā wahi pili i kahi bearing e hōʻemi i ka friction, hoʻopau i ka wela a keʻakeʻa i ka corrosion ma nā pōpō a me nā ala heihei.He mea koʻikoʻi ka ʻino o ka ʻili a me ka maikaʻi o ka lubrication e pili ana i ka pilikia o ka ʻili a ʻaʻole paha.

ʻO ke koho ʻana i ka lubricant kūpono.I loko o kahi kaiapuni kahi e hiki ai ke ʻino ʻino ma waho o ka bearing, ʻaʻole pono e ʻae ʻia i loko.Hiki i nā SMB Bearings ke hāʻawi i nā bearings i hoʻopaʻa ʻia me nā momona wai ʻole i loaʻa i nā mea hoʻopale corrosion.Mālama kēia mau lubricants i nā ʻili o loko o ka bearing a hiki ke hoʻohālikelike ʻia me ka ʻenehana noi waho.ʻO nā bearings seramika piha ka hapa nui me ka ʻole o ka lubrication akā hiki ke lubricated me ka momona wai no ke ola lōʻihi.

C-Sal

Ma nā wahi paʻakikī, ʻoi aku ka nui o ka pale ʻana i ka ʻino, no laila ʻoi aku ka maikaʻi o ke koho ʻana i kahi sila hoʻopili e hōʻoia i ke komo ʻole o nā mea haumia i ka bearing.No nā mea hana i ʻike ʻia i ka makū, e hāʻawi pū kekahi sila pili i ka hoʻonui ʻana i ka wai.Hoʻopau kēia i ka holoi ʻana i ka ʻaila mai ka bearing, e ʻae iā ia e hana i kāna hana i ka lubricating a me ka pale ʻana i nā ʻili o loko o ka bearing.ʻO kahi koho ʻē aʻe he pale metala akā hāʻawi kēia i ka pale hoʻemi nui ʻana i ka makū.

Ma ka loiloi ʻana i ke kaiapuni hana, koi ʻia ka lōʻihi a me nā ukana e hoʻopili ʻia i ka bearing, ʻo ka bearing maikaʻi loa ʻo ia ka 'wonky vegetable' haʻahaʻa a ʻaʻole ka mea e mau ana i ka nani no ka lōʻihi.Ma ka noʻonoʻo ʻana i nā kūlana hana kaiapuni piha o kahi bearing, hiki i nā mea hoʻolālā hoʻolālā ke kaupaona inā ʻoi aku ka maikaʻi o ke koho ʻana i kahi hiʻohiʻona hoʻolālā corrosion control, hoʻonui i ke ola o ka bearing a hoʻokiʻekiʻe i ka hana o ka mīkini.
