"Hoʻololi hou i ka nānā ʻana i nā mīkini hana kūkulu: ʻo ka mana o ka ʻāpana Magnetic a me ka nānā ʻana i ka X-Ray"

hoʻolauna:
I kēia ao wikiwiki wikiwiki, aia ka koi mau no nā mīkini hana kiʻekiʻe.Mai nā mea hana koʻikoʻi a hiki i nā ʻāpana automotive paʻakikī, e hōʻoia i ka pono a me ka hilinaʻi o nā castings he mea koʻikoʻi.No ka hoʻokō ʻana i kēia mau koi koʻikoʻi, ke huli nei nā ʻoihana i nā ʻenehana nānā ʻokiʻoki.Ma kēia pou blog, ʻimi mākou i ka honua o ka nānā ʻana i nā ʻāpana magnetic a me ka nānā ʻana i ka X-ray e ʻimi ai pehea e hoʻololi ai kēia mau ʻano holomua i ke ʻano o ka nānā ʻana i nā mīkini hana.
E aʻo e pili ana i ka nānā ʻana i nā ʻāpana magnetic:
ʻO ka nānā ʻana i ka ʻāpana magnetik (MPI) kahi hana hoʻāʻo ʻole luku i hoʻohana ʻia e ʻike i nā hemahema o ka ʻili a me ka lalo o nā mea ferromagnetic e like me ka hao a i ʻole ke kila.ʻO ke kumu ma hope o kēia ʻenehana ʻo ia ka hiki ke hana i kahi māla magnetic i ka ʻāpana e nānā ʻia e ʻike i nā hemahema.Loaʻa iā ia nā ʻanuʻu aʻe:
1. Mākēneki: E hoʻohana i nā mea hoʻokalakupua o kēia manawa (DC) a i ʻole nā mea hoʻoheheʻe ʻia (AC) e hoʻomākeʻe i ka hoʻolei ʻana e hoʻohua ai i kahi mākena i loko o ka mea.
2. Ka hoʻohana ʻana i nā ʻāpana magnetic: Hoʻopili ʻia nā ʻāpana magnetic i hoʻokaʻawale maikaʻi ʻia (maloʻo a hoʻopaneʻe ʻia paha i loko o kahi ʻano wai) i ka ʻili magnetized.Hoʻopili ʻia kēia mau ʻāpana i nā hemahema e kū nei, e hana ana i nā hōʻailona ʻike ʻia.
3. Nānā: E nānā i ka ʻili a me ka nānā ʻana i ka hōʻailona ʻāpana magnetic.Hiki i nā mākaʻikaʻi akamai loa ke hoʻokaʻawale i waena o nā hewa ʻole o ka ʻili a me nā hōʻailona hiki ke hoʻololi i ka pono.
Nā pōmaikaʻi o ka hoʻāʻo ʻana i nā ʻāpana magnetic:
ʻO ka hoʻohana ʻana i ka nānā ʻana i nā ʻāpana magnetic he nui nā pono, e like me:
1. Ka ʻili a me ka ʻili kokoke i ka ʻili: Hiki i ka MPI ke ʻike i nā hemahema e like me nā māwae, pores, overlaps, seams, a me nā mea ʻole ʻē aʻe, e hōʻoia ana i kahi loiloi piha o ka hoʻolei ʻana i ka pono.
2. ʻO ka manawa a me ke kumukūʻai kūpono: He wikiwiki kēia ala nānā a hiki ke loiloi wikiwiki i nā helu he nui.Mālama ia i ka manawa waiwai a me nā kumuwaiwai a hoʻonui i ka huahana.
3. ʻO ka hoʻāʻo ʻole ʻana: ʻO MPI kahi ʻenehana hoʻopau ʻole e mālama i ka pono o nā ʻāpana i nānā ʻia.Hoʻemi ia i ka pono o nā ʻano hoʻāʻo hoʻopau, e hōʻemi ana i ka ʻōpala a me nā kumukūʻai.
4. Hoʻonui i ka palekana: Ma ka ʻike ʻana i nā hemahema, hiki i ka MPI ke hōʻoia i ka palekana o nā mea hana mīkini hana a me nā mea hoʻohana, e pale ana i nā hemahema pōʻino.
E ʻimi i ka X-Ray Inspection:
Hoʻopili ka nānā ʻana i nā ʻāpana magnetik i nā hemahema o ka ʻili, ʻoiai ʻo ka nānā ʻana i ka X-ray e hele hohonu ana i loko o ke ʻano o loko o kahi hoʻolei.Hoʻohana ka nānā ʻana i ka X-ray i ka radiation electromagnetic ikaika nui e komo i nā mea e hana ai i nā kiʻi radiographic.He waiwai kēia ʻenehana no ka ʻike ʻana i nā hemahema o loko e like me:
1. Pores and voids: X-ray inspectionally identified any trapped gas or shrinkage voids in the casting, e hōʻoiaʻiʻo structural integrity and functionality.
2. Hoʻokomo a me nā mea'ē aʻe: ʻO ka hiki ke nānā i nā hale i loko e hiki ai i nā mea nānā keʻike i nā mea i makemakeʻoleʻia a iʻole nā mea'ē aʻe, e hōʻoiaʻiʻo ana i ka'āpana e hoʻokō i nā kiko'ī i koiʻia.
3. Geometric a me ka pololei pololei: ʻO ka nānā ʻana i ka X-ray e kōkua i ka loiloi ʻana i ka pololei o ke ana a me ka hoʻokō ʻana i nā kikoʻī hoʻolālā, a laila e hōʻemi i ka pilikia o ka hāʻule ʻana ma muli o ke kuhi hewa ʻana o nā mea.
Synergies: Hoʻohui ʻia o MPI a me X-ray Inspection:
ʻOiai ʻo ka nānā ʻana i ka ʻāpana magnetic a me ka nānā ʻana i ka X-ray he mau hana hoʻāʻo ʻole luku ʻole, ʻo ka hopena synergistic o ka hoʻohui ʻana i kēia mau ʻenehana hiki ke hāʻawi i ka loiloi piha loa o ka pono o nā hoʻolei mīkini hana.Ma ka hoʻohana ʻana i nā ʻenehana ʻelua i ka manawa like, hiki i nā mea hana ke ʻike wiwo ʻole i nā hemahema mai nā anomalies o ka ʻili a i nā hemahema o loko.Hoʻohui ʻia, hiki i ka hui ʻana i kēia mau ʻano hana ke hoʻomaikaʻi i ka hilinaʻi ma o ka hoʻopaʻa ʻana i nā hopena, e hōʻemi hou ana i ka manawa o nā hemahema koʻikoʻi e nānā ʻole ʻia.
i ka hopena:
Ke hoʻomau nei ka noi ʻana no ka hoʻoheheʻe ʻana i nā mīkini hana kiʻekiʻe, ua lilo ka nānā ʻana i nā ʻāpana magnetic a me ka nānā ʻana i ka X-ray i mea pono e hōʻoia ai i ka hilinaʻi, ka hoʻonohonoho pono a me ka palekana o ka mea hana.Ma ka hoʻohana ʻana i kēia mau ʻenehana maikaʻi loa, ʻaʻole luku ʻia, hiki i nā mea hana ke ʻike koke i nā hemahema a pale i ka downtime kumu kūʻai a me nā pōʻino.ʻO ka hui pū ʻana o ka nānā ʻana i nā ʻāpana magnetic a me ka nānā ʻana i ka X-ray e hōʻailona i kahi kiʻi kipi no ka ʻoihana no ka mea e hāʻawi ana i kahi ʻike piha o ke ʻano o ka hoʻolei ʻana.Ma ka ʻae ʻana i kēia mau holomua, ke hana nei mākou i nā lele nui i kahi palekana a ʻoi aku ka maikaʻi o ka wā e hiki mai ana no nā mīkini hana.
