Ⅰ. He aha ka hoʻāʻo ʻole luku?
Ma ka ʻōlelo maʻamau, hoʻohana ʻia ka hoʻāʻo non-destructive i nā hiʻohiʻona o ke kani, ka māmā, ka uila a me ka magnetism e ʻike ai i ka wahi, ka nui, ka nui, ke ʻano a me nā ʻike pili ʻē aʻe e pili ana i ka ʻili a i ʻole nā hemahema o loko ma ka ʻili o ka mea me ka ʻole e hōʻino i ka mea ponoʻī. .Non-destructive ho'āʻo manaʻo e ike i ke kūlana oaoieei o nā mea, e like me ka mea i kūpono a i koe ke ola lawelawe, me ka hoʻopilikia ole i ka wā e hiki mai ana o na mea. ʻo ka hoʻāʻo ʻāpana, ma waena o ka Ultrasonic Test kekahi o nā ʻano hana maʻamau.
Ⅱ. ʻElima mau ʻano hoʻokolohua maʻamau ʻaʻole luku:
1.ʻO ka wehewehe ʻana i ka Ultrasonic Test
ʻO ka Ultrasonic Test kahi ala e hoʻohana ai i nā ʻano o nā hawewe kani ultrasonic e hoʻolaha a noʻonoʻo i nā mea e ʻike ai i nā hemahema o loko a i ʻole nā mea ʻē i loko o nā mea. Hiki iā ia ke ʻike i nā hemahema like ʻole, e like me nā māwae, pores, inclusions, looseness, etc. ʻO ka ʻike ʻana i ka flaw ultrasonic he kūpono ia no nā mea like ʻole, a hiki ke ʻike i ka mānoanoa o nā mea, e like me nā metala, nā mea ʻole, nā mea hoʻohui, etc. ʻo ia kekahi o nā hana maʻamau i hoʻohana ʻia i ka hoʻāʻo ʻole luku.
No ke aha i ʻoi aku ka maikaʻi o nā pā kila mānoanoa, nā paipu pā mānoanoa a me nā kaola pōʻai nui-nui no ka hoʻāʻo UT?
① Ke nui ka mānoanoa o ka mea, hiki ke hoʻonui ʻia nā hemahema o loko e like me nā pores a me nā māwae.
②Hoʻokumu ʻia nā forgings ma ke kaʻina hana forging, hiki ke hana i nā hemahema e like me nā pores, inclusions, a me nā māwae i loko o ka mea.
③Hoʻohana mau ʻia nā paipu pā mānoanoa a me nā koʻokoʻo pōʻai ākea nui i ke koi ʻana i nā hale ʻenekinia a i ʻole nā kūlana e kaumaha nui ai. Hiki i ka ho'āʻo UT ke komo hohonu i loko o ka mea a loaʻa i nā hemahema o loko, e like me nā māwae, inclusions, a me nā mea ʻē aʻe, he mea koʻikoʻi ia e hōʻoia i ka pono a me ka palekana o ka hale.
2.PENETRANT TEST wehewehe
Nā hiʻohiʻona kūpono no UT Test a me PT Test
He kūpono ka ho'āʻo UT no ka ʻike ʻana i nā hemahema o loko o nā mea, e like me nā pores, inclusions, māwae, etc. Hiki i ka ho'āʻo UT ke komo i ka mānoanoa mea a ʻike i nā hemahema i loko o ka mea ma ka hoʻokuʻu ʻana i nā hawewe kani ultrasonic a loaʻa nā hōʻailona hōʻike.
He kūpono ka ho'āʻo PT no ka ʻike ʻana i nā hemahema o ka ʻili ma ka ʻili o nā mea, e like me nā pores, inclusions, cracks, etc. Ke hilinaʻi nei ka hoʻāʻo ʻana o PT i ke komo ʻana o ka wai i loko o nā māwae a i ʻole nā hemahema a hoʻohana i ka mea hoʻomohala kala e hōʻike i kahi a me ke ʻano o nā hemahema.
Loaʻa i ka hōʻike UT a me ka hōʻike PT ko lākou pono ponoʻī a me nā hemahema i nā noi hana. E koho i ke ʻano hoʻāʻo kūpono e like me nā pono hoʻāʻo like ʻole a me nā ʻano waiwai e loaʻa ai nā hopena hoʻāʻo maikaʻi aʻe.
3.Eddy o keia manawa
（1）Hoʻolauna i ka hoʻāʻo ET
Hoʻohana ʻo ET Test i ka loina o ka electromagnetic induction e lawe mai i kahi coil hoʻāʻo e lawe ana i kēia manawa kokoke i kahi mea hana conductor e hoʻohua i nā au eddy. Ma muli o nā hoʻololi o nā au eddy, hiki ke ʻike ʻia nā waiwai a me ke kūlana o ka mea hana.
(2）)Pono o ka hoao ET
ʻAʻole koi ʻo ET Test i ka hoʻopili ʻana me ka mea hana a i ʻole ka waena, wikiwiki loa ka wikiwiki o ka ʻike, a hiki iā ia ke hoʻāʻo i nā mea non-metallic i hiki ke hoʻoulu i nā au eddy, e like me ka graphite.
（3）Ka palena o ka ho'āʻo ET
Hiki iā ia ke ʻike i nā hemahema ili o nā mea conductive. Ke hoʻohana nei i kahi coil through-type no ET, ʻaʻole hiki ke hoʻoholo i kahi kikoʻī o ka hemahema ma ka pōʻai.
(4) ʻO nā kumukūʻai a me nā pōmaikaʻi
Loaʻa iā ET Test nā mea hana maʻalahi a maʻalahi ka hana. ʻAʻole ia e koi i ka hoʻomaʻamaʻa paʻakikī a hiki ke hana wikiwiki i ka hoʻāʻo manawa maoli ma ka pūnaewele.
ʻO ke kumu kumu o ka hoʻāʻo PT: ma hope o ka uhi ʻia ʻana o ka ʻāpana me ka fluorescent dye a i ʻole ka waihoʻoluʻu kala, hiki i ka penetrant ke komo i loko o ka wehe ʻana i nā hemahema ma lalo o ka manawa o ka hana capillary; ma hope o ka wehe 'ana i ka nui penetrant ma luna o ka ili o ka hapa, ka hapa hiki e Apply developer i ka ili. Pēlā nō, ma lalo o ka hana a ka capillary, e huki ka mea hoʻomohala i ka penetrant i hoʻopaʻa ʻia i loko o ka defect, a e hoʻi hou ka penetrant i ka mea hoʻomohala. Ma lalo o kekahi kumu kukui (ke kukui ultraviolet a i ʻole ke kukui keʻokeʻo), e hōʻike ʻia nā meheu o ka penetrant i ka hemahema. , (ʻulaʻula melemele-'ōmaʻomaʻo a i ʻole ʻulaʻula ʻulaʻula), ma laila e ʻike ai i ka morphology a me ka hāʻawi ʻana i nā hemahema.
4. Ho'āʻo Māmā
ʻO Magnetic Particle Testing" kahi hana hoʻāʻo ʻole luku ʻole no ka ʻike ʻana i nā hemahema o ka ʻili a kokoke i ka ʻili o nā mea conductive, ʻoi aku ka nui o ka ʻike ʻana i nā māwae. nā hemahema o lalo o ka ʻāina.
5. KA HOʻOʻI LOA
（1）Hoʻolauna i ka hōʻike RT
ʻO nā kukui X he mau nalu electromagnetic me ke alapine kiʻekiʻe loa, ka lōʻihi hawewe pōkole loa, a me ka ikehu kiʻekiʻe. Hiki iā lākou ke komo i nā mea hiki ʻole ke komo ʻia e ka mālamalama ʻike ʻia, a komo i nā hopena paʻakikī me nā mea i ka wā o ke kaʻina hana.
（2） Nā pono o ka ho'āʻo RT
Hiki ke hoʻohana ʻia ka RT Test no ka ʻike ʻana i nā hemahema o loko o nā mea, e like me nā pores, inclusion cracks, etc., a hiki ke hoʻohana ʻia e loiloi i ka pono o ka hale a me ka maikaʻi o loko o nā mea.
（3）Ke kumu o ka ho'āʻo RT
ʻIke ʻo RT Test i nā hemahema i loko o ka mea ma ka hoʻokuʻu ʻana i nā kukui X a me ka loaʻa ʻana o nā hōʻailona hōʻike. No nā mea ʻoi aku ka mānoanoa, ʻo ka hoʻāʻo UT kahi ala kūpono.
（4）Ka palena o ka ho'āʻo RT
Loaʻa i ka hōʻike RT kekahi mau palena. Ma muli o kona lōʻihi nalu a me nā hiʻohiʻona ikehu, ʻaʻole hiki i nā kukui X ke komo i kekahi mau mea, e like me ke alakaʻi, ka hao, ke kila kila, a pēlā aku.
