Ⅰ.Kodi kuyesa kosawononga ndi chiyani?
Nthawi zambiri, kuyesa kosawononga kumagwiritsa ntchito mawonekedwe a phokoso, kuwala, magetsi ndi maginito kuti azindikire malo, kukula, kuchuluka, chilengedwe ndi zina zokhudzana ndi pafupi ndi pamwamba kapena zolakwika zamkati pamwamba pa zinthuzo popanda kuwononga zinthuzo. .Kuyesa kosawononga kumafuna kudziwa momwe zida zilili, kuphatikiza ngati zili zoyenerera kapena zili ndi moyo wautumiki wotsalira, osakhudza momwe zinthuzo zidzakhalire m'tsogolo.Njira zoyezetsa zosawononga zomwe zimadziwika kuti ultrasonic test, electromagnetic test, ndi maginito particle test, yomwe akupanga Mayeso ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri.
Ⅱ.Njira zisanu zodziwika bwino zosawononga:
1.Tanthauzo la Mayeso a Akupanga
Akupanga Mayeso ndi njira yomwe imagwiritsa ntchito mawonekedwe a mafunde akupanga kufalitsa ndikuwonetsa muzinthu kuti azindikire zolakwika zamkati kapena zinthu zakunja muzinthu. Imatha kuzindikira zolakwika zosiyanasiyana, monga ming'alu, pores, inclusions, looseness, etc. Akupanga cholakwa kuzindikira ndi oyenera zipangizo zosiyanasiyana, komanso kudziwa makulidwe a zipangizo, monga zitsulo, sanali zitsulo, gulu zipangizo, etc. ndi imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri pakuyesa kosawononga.
Chifukwa chiyani mbale zachitsulo zokhuthala, mapaipi amipanda yokhuthala ndi mipiringidzo yozungulira yozungulira ikuluikulu ali oyenera kuyesedwa kwa UT?
① Pamene makulidwe azinthuzo ndi aakulu, kuthekera kwa zolakwika zamkati monga pores ndi ming'alu kumawonjezeka moyenerera.
②Mapangidwe amapangidwa ndi njira yopangira, zomwe zingayambitse zolakwika monga pores, inclusions, ndi ming'alu mkati mwazinthu.
③Mapaipi okhala ndi mipanda yokhuthala ndi ndodo zozungulira zazikulu nthawi zambiri amagwiritsidwa ntchito popanga zomangamanga kapena malo omwe amakhala ndi nkhawa kwambiri. Kuyesa kwa UT kumatha kulowa mkati mwazinthu ndikupeza zolakwika zamkati, monga ming'alu, zophatikizika, ndi zina zambiri, zomwe ndizofunikira kuti zitsimikizire kukhulupirika ndi chitetezo cha kapangidwe kake.
2.PENETRANT TEST tanthauzo
Zochitika zovomerezeka za UT Test ndi PT Test
UT mayeso ndi oyenera kudziwa zolakwika mkati mwa zipangizo, monga pores, inclusions, ming'alu, etc. UT mayeso akhoza kudutsa makulidwe zinthu ndi kuzindikira zolakwika mkati mwa zinthu ndi emitting akupanga mafunde ndi kulandira anasonyeza zizindikiro.
Kuyesa kwa PT ndikoyenera kuzindikira zolakwika zapamtunda pazida, monga pores, inclusions, ming'alu, ndi zina. Kuyezetsa kwa PT kumadalira kulowa kwamadzi mu ming'alu kapena zolakwika ndipo amagwiritsa ntchito wopanga utoto kuti awonetse malo ndi mawonekedwe a zolakwika.
Mayeso a UT ndi mayeso a PT ali ndi zabwino ndi zovuta zawo pazogwiritsa ntchito. Sankhani njira yoyenera yoyezera malinga ndi zosowa zosiyanasiyana zoyezetsa ndi mawonekedwe azinthu kuti mupeze zotsatira zabwinoko zoyezetsa.
3.Eddy Panopa Mayeso
(1) Chiyambi cha ET Test
ET Test imagwiritsa ntchito mfundo ya ma elekitiromagineti induction kubweretsa koyilo yoyeserera yonyamula pakali pano pafupi ndi chogwirira ntchito kuti apange mafunde a eddy. Kutengera kusintha kwa mafunde a eddy, katundu ndi mawonekedwe a workpiece amatha kuganiziridwa.
(2) Ubwino wa ET Test
ET Mayeso safuna kukhudzana ndi workpiece kapena sing'anga, liwiro kudziwika ndi mofulumira kwambiri, ndipo akhoza kuyesa zinthu sanali zitsulo zomwe zingachititse mafunde eddy, monga graphite.
(3) Zochepa za ET Test
Itha kungozindikira zolakwika zapamtunda za zida zowongolera. Mukamagwiritsa ntchito koyilo yamtundu wa ET, ndizosatheka kudziwa malo enieni a cholakwikacho pa circumference.
(4) Mtengo ndi zopindulitsa
ET Test ili ndi zida zosavuta komanso ntchito yosavuta. Sichifuna maphunziro ovuta ndipo amatha kuyesa nthawi yeniyeni pamalopo.
Mfundo yofunikira ya mayeso a PT: pambuyo pa gawolo litakutidwa ndi utoto wa fulorosenti kapena utoto wamitundu, wolowera amatha kulowa muvuto lotseguka pansi pa nthawi ya capillary; pambuyo kuchotsa owonjezera olowera pamwamba pa gawo, gawo akhoza Ikani mapulogalamu pamwamba. Momwemonso, pansi pa zochita za capillary, woyambitsayo adzakopa olowera omwe amasungidwa mu chilema, ndipo wolowerayo adzabwereranso ku woyambitsa. Pansi pa gwero linalake la kuwala (kuwala kwa ultraviolet kapena kuwala koyera), zizindikiro za cholowera pachilema zidzawonetsedwa. , (yellow-green fluorescence kapena wofiira wowala), potero amazindikira morphology ndi kufalitsa zolakwika.
4.Kuyesa kwa Magnetic Particle
Magnetic Particle Testing" ndi njira yoyesera yosawononga yomwe imagwiritsidwa ntchito nthawi zambiri kuti izindikire zolakwika zapamtunda ndi pafupi ndi pamwamba pa zinthu zoyendetsa, makamaka pozindikira ming'alu. zolakwika zapansi panthaka.
5.RADIOGRAPHIC TEST
(1) Chiyambi cha RT Test
Ma X-ray ndi mafunde a electromagnetic okhala ndi ma frequency okwera kwambiri, kutalika kwake kwakanthawi kochepa, komanso mphamvu zambiri. Amatha kulowa m'zinthu zomwe sizingalowemo ndi kuwala kowonekera, ndikukumana ndi zovuta ndi zipangizo panthawi yolowera.
(2) Ubwino wa RT Test
Mayeso a RT angagwiritsidwe ntchito kuti azindikire zolakwika zamkati mwazinthu, monga pores, ming'alu yophatikizika, ndi zina zambiri, ndipo zitha kugwiritsidwanso ntchito kuwunika kukhulupirika kwamapangidwe ndi mtundu wamkati wazinthu.
(3) Mfundo ya RT Test
Mayeso a RT amazindikira zolakwika mkati mwazinthu potulutsa ma X-ray ndikulandila zikwangwani zowonekera. Pazinthu zokhuthala, kuyesa kwa UT ndi njira yabwino.
(4) Zochepa za RT Test
RT Test ili ndi malire. Chifukwa cha kutalika kwake komanso mphamvu zake, ma X-ray sangathe kulowa muzinthu zina, monga lead, iron, chitsulo chosapanga dzimbiri, ndi zina.
