Ukuhlola okungabhubhisi ukusetshenziswa kwezakhiwo ze-acoustic, optical, kazibuthe nezikagesi, ngaphandle kokulimaza noma ukuphazamisa ukusetshenziswa kwento engaphansi kwesisekelo sokusebenza kwento ezohlolwa, ukuze kutholwe ubukhona bokukhubazeka noma ukungatholakali kwe-homogeneity entweni. ihlolwe, ukunikeza ubukhulu bezinkinga, indawo okushiyeke kuyo, uhlobo lwenani lolwazi nokunye, bese kunquma isimo sobuchwepheshe bento ezohlolwa (isib., efanelekayo noma engafaneleki, impilo eyinsalela. nokunye) zonke izindlela zobuchwepheshe zethemu elijwayelekile.
Izindlela zokuhlola ezivame ukusetshenziswa ezingonakali: Ukuhlolwa kwe-Ultrasonic (UT), Ukuhlola I-Magnetic Particle (MT), Ukuhlolwa Kokungena Kwe-Liquid (PT) nokuhlolwa kwe-X-ray (RT).
Ukuhlolwa kwe-Ultrasonic
I-UT (Ukuhlolwa kwe-Ultrasonic) ingenye yezindlela zokuhlola ezingabhubhi embonini. Amagagasi e-Ultrasonic entweni okuhlangatshezwane nayo iziphambeko, ingxenye yegagasi lomsindo izobonakala, isidlulisi nomamukeli singahlaziya igagasi elibonisiwe, kungaba isilinganiso esinembe kakhulu sokukhubazeka. Futhi ingabonisa indawo kanye nobukhulu bezinkinga zangaphakathi, inqume ukushuba kwezinto.
Izinzuzo zokuhlolwa kwe-Ultrasonic:
1, ikhono lokungena likhulu, isibonelo, kunsimbi ekujuleni okusebenzayo kokutholwa okungafika kumitha elingu-1 noma ngaphezulu;.
2, ngokulimala kohlobo lwendiza njengokuqhekeka, izixhumi ezihlanganayo, njll., ukutholwa kokuzwela okuphezulu, futhi kunganquma ukujula nosayizi ohlobene weziphambeko;
I-3, imishini engasindi, ukusebenza okuphephile, ukuhlola okuzenzakalelayo okulula ukukubona.
Ububi:
Akulula ukuhlola ukuma okuyinkimbinkimbi kwe-workpiece, kudinga izinga elithile lokushelela kwendawo ehloliwe, futhi i-ejenti yokuhlanganisa iyadingeka ukuze igcwalise igebe phakathi kwe-probe nendawo ehloliwe ukuze kuqinisekiswe ukuhlangana okwanele kwe-acoustic.
Ukuhlola Izinhlayiya Zezibuthe
Okokuqala, ake siqonde isimiso sokuhlolwa kwezinhlayiyana kazibuthe. Ngemuva kokusebenza kazibuthe kwezinto ezisetshenziswayo ze-ferromagnetic kanye nezinto zokusebenza, ngenxa yokuba khona kokunqamuka, imigqa kazibuthe yamandla ebusweni bomsebenzi kanye eduze nendawo yokuhlanekezela kwendawo, futhi ikhiqize insimu yokuvuza, i-adsorption yempusha kazibuthe esetshenziswa phezulu. yocezu lokusebenza, yenza umkhondo kazibuthe obonakalayo ekukhanyeni okufanele, ngaleyo ndlela ibonise indawo, ukwakheka nosayizi wokuyeka.
Ukusebenza kanye nemikhawulo yokuhlolwa kwezinhlayiyana kazibuthe yilezi:
1, ukutholwa kokungasebenzi kahle kwezinhlayiyana kazibuthe kulungele ukuthola ukungaqhubeki endaweni yezinto ezisetshenziswayo ze-ferromagnetic naseduze kwendawo enosayizi omncane kakhulu nezikhala ezincane kakhulu okunzima ukuzibona ngokubonakalayo.
2, ukuhlolwa kwezinhlayiya kazibuthe kungaba izimo ezihlukahlukene zokutholwa kwezingxenye, kodwa futhi nezinhlobo zezingxenye ezizotholwa.
I-3, ingathola imifantu, i-inclusions, i-hairline, amabala amhlophe, ukugoqa, ukuhlukaniswa okubandayo kanye okuxekethile nokunye ukukhubazeka.
4, ukuhlolwa kwezinhlayiya kazibuthe akukwazi ukubona izinto zensimbi engagqwali ye-austenitic kanye nama-welds ashiselwe ngama-electrode ensimbi engenasici ye-austenitic, futhi ayikwazi ukubona ithusi, i-aluminium, i-magnesium, i-titanium nezinye izinto ezingezona kazibuthe. Kubuso bemihuzuko engashoni, izimbobo ezigqitshiwe ezijulile kanye ne-engeli yangaphezulu ye-workpiece engaphansi kuka-20 ° delamination nokugoqeka kunzima ukuyithola.
Ukutholwa kokungena koketshezi
Isimiso esiyisisekelo sokutholwa kokungena kwe-liquid, indawo engaphezulu yengxenye ifakwe odayi be-fluorescent noma odayi bombala, esikhathini esithile ngaphansi kwesenzo se-capillary, uketshezi olungena ngaphakathi lungangena kumaphutha okuvula phezulu; ngemva kokukhipha uketshezi olungena okweqile ebusweni bengxenye, bese lumbozwa ngomthuthukisi ebusweni bengxenye.
Ngokufanayo, ngaphansi kwesenzo se-capillary, umthuthukisi uzoheha iziphambeko ekugcineni i-permeate, angene abuyele kunjiniyela, emthonjeni othile wokukhanya (ukukhanya kwe-ultraviolet noma ukukhanya okumhlophe), amaphutha ekulandeleleni kwe-permeate ayaboniswa, ( i-fluorescent ephuzi-luhlaza noma okubomvu okukhanyayo), ukuze kutholwe amaphutha e-morphology nokusatshalaliswa kombuso.
Izinzuzo zokutholwa kokungena yilezi:
1, ingakwazi ukubona izinto ezihlukahlukene;
2, unokuzwela okuphezulu;
3, isibonisi sinembile, kulula ukusebenza, izindleko zokutholwa ziphansi.
Futhi ububi bokuhlolwa kokungena yilezi:
1, ayifanele ukuhlolwa kwempahla evulekile enezimbotshana eyenziwe ngezinto zokusebenza nezinto zokusebenza ezingaphezulu;
2, ukuhlolwa kokungena kungathola kuphela ukusabalaliswa okungaphezulu kweziphambeko, kunzima ukunquma ukujula kwangempela kweziphambeko, ngakho-ke kunzima ukwenza ukulinganisa kwenani lamaphutha. Imiphumela yokutholwa nayo ithintwa u-opharetha.

Ukuhlolwa kwe-X-ray
Okokugcina, ukutholwa kwe-ray, ngoba ama-X-ray ento ekhanyiswe ayoba nokulahlekelwa, ubukhulu obuhlukene bezinto ezihlukene ngesilinganiso sokumuncwa kwehlukile, futhi okunegethivu kubekwa ngakolunye uhlangothi lwento ekhanyiswe, ngoba ukuqina kwemisebe. zihlukile futhi zikhiqiza umfanekiso ohambisanayo, abahloli befilimu bangasuselwa esithombeni ukuze banqume ukuthi kukhona yini ukukhubazeka ngaphakathi kwento kanye nemvelo yokukhubazeka.
Ukusebenza kanye nemikhawulo yokutholwa kwe-ray:
I-1, izwela kakhulu ukuthola ukukhubazeka kwe-volumetric, kulula ukuveza amaphutha.
2, i-ray negative kulula ukuyigcina, kukhona ukulandeleka.
3, ukubona ngeso lomumo kanye nohlobo lwamaphutha.
I-4, ukungalungi akukwazi ukuthola ukujula okugqitshiwe kokukhubazeka, kuyilapho ukutholwa kokuqina okulinganiselwe, okungalungile kudinga ukuthunyelwa ngokuqondile ukuze kugezwe, futhi umzimba womuntu unomonakalo othile, izindleko ziphakeme.
Ngamafuphi, i-ultrasonic, i-X-ray yokubona amaphutha ifaneleka ukuthola amaphutha angaphakathi; lapho i-ultrasonic engaphezu kuka-5mm, kanye nokuma kwezingxenye ezivamile, i-X-ray ayikwazi ukuthola ukujula okugqitshiwe kokukhubazeka, imisebe. Izinhlayiya zikaZibuthe kanye nokutholwa kwamaphutha okungena kulungele ukuthola amaphutha ebusweni bezingxenye; phakathi kwazo, ukutholwa kokungasebenzi kahle kwezinhlayiyana kazibuthe kukhawulelwe ekutholeni izinto ezisetshenziswa kazibuthe, futhi ukutholwa kwamaphutha okungena kunqunyelwe ekutholeni amaphutha avulekile phezulu.
