Ukuhlola okungalimazi kuwukusebenzisa izici zomsindo, ukukhanya, uzibuthe kanye nogesi ukuze kutholwe ukuthi kukhona yini ukukhubazeka noma ukunganaki entweni okufanele ihlolwe ngaphandle kokulimaza noma ukuphazamisa ukusebenza kwento ezohlolwa, kanye nokunikeza usayizi wento okufanele ihlolwe. , indawo, nendawo yesici. Itemu elivamile lazo zonke izindlela zobuchwepheshe zokunquma isimo sobuchwepheshe sento ehloliwe (njengokuthi ifanelekile noma cha, impilo esele, njll.)
Izindlela zokuhlola ezivame ukusetshenziswa ezingonakalisi: ukuhlolwa kwe-ultrasonic (UT), ukuhlolwa kwezinhlayiyana kazibuthe (MT), ukuhlolwa kwe-liquid penetrant (PT) nokuhlolwa kwe-X-ray (RT).
Ukuhlolwa kwe-ultrasonic
I-UT (Ukuhlolwa kwe-Ultrasonic) ingenye yezindlela zokuhlola ezingabhubhisi zezimboni. Lapho igagasi le-ultrasonic lingena entweni futhi lihlangabezana nenkinga, ingxenye yegagasi lomsindo izobonakala, futhi isidlulisi nomamukeli singahlaziya igagasi elibonisiwe, futhi iphutha lingatholwa ngokunembe kakhulu. Futhi ingabonisa isikhundla nosayizi weziphambeko zangaphakathi, ukukala ukujiya kwezinto, njll.
Izinzuzo zokuhlolwa kwe-ultrasonic:
1. Ikhono elikhulu lokungena, isibonelo, ukujula kokutholwa okusebenzayo kwensimbi kungafinyelela ngaphezu kwemitha eyi-1;
2. Ngokukhubazeka okuhleliwe okufana nokuqhekeka, ama-interlayers, njll., ukuzwela kokutholwa kuphezulu, futhi ukujula nosayizi ohlobene wokukhubazeka kungalinganiswa;
3. Imishini iyaphatheka, ukusebenza kuphephile, futhi kulula ukubona ukuhlolwa okuzenzakalelayo.
ukushiyeka:
Akulula ukuhlola ama-workpiece anomumo oyinkimbinkimbi, futhi indawo okufanele ihlolwe iyadingeka ukuze ibe nezinga elithile lokushelela, futhi igebe phakathi kwe-probe kanye nendawo okufanele ihlolwe kufanele igcwaliswe nge-couplant ukuze kuqinisekiswe ukuhlangana okwanele kwe-acoustic.
Ukuhlolwa Kwezinhlayiya Ezizibuthe
Okokuqala, masiqonde isimiso sokuhlolwa kwezinhlayiyana kazibuthe. Ngemuva kokuthi impahla ye-ferromagnetic kanye nomsebenzi kufakwe uzibuthe, ngenxa yokuba khona kokuyeka, imigqa yensimu kazibuthe ngaphezulu naseduze kwendawo yokusebenza iyahlanekezelwa endaweni, okuholela ekuvuzeni kwensimu kazibuthe, emunca impusha kazibuthe esetshenziswa endaweni yokusebenza. indawo yokusebenza, futhi yakha insimu yamagnetic ebonakalayo ngaphansi kokukhanya okufanele. imikhondo, ngaleyo ndlela ikhombisa indawo, ukwakheka kanye nosayizi wokuyeka.
Ukusebenza kanye nemikhawulo yokuhlolwa kwezinhlayiyana kazibuthe yilezi:
1. Ukuhlolwa kwezinhlayiyana zikazibuthe kulungele ukuthola okungaqhubeki kuncane ngosayizi endaweni kanye eduze nendawo yezinto ze-ferromagnetic, futhi igebe lincane kakhulu futhi kunzima ukulibona ngokubonakalayo.
2. Ukuhlolwa kwezinhlayiya zikazibuthe kungathola izingxenye ezimweni ezihlukahlukene, futhi kungathola izinhlobo ezihlukahlukene zezingxenye.
3. Amaphutha afana nokuqhekeka, okufakiwe, izintambo zezinwele, amabala amhlophe, ukugoqa, ukuvala okubandayo kanye nokuxega kungatholakala.
4. Ukuhlolwa kwezinhlayiya zikazibuthe akukwazi ukubona izinto zensimbi engagqwali ye-austenitic kanye namawelds ashiselwe ngama-electrode ensimbi engenasici ye-austenitic, futhi ngeke kukwazi ukubona izinto ezingezona kazibuthe njengethusi, i-aluminium, i-magnesium ne-titanium. Kunzima ukuthola ama-delaminations kanye nokugoqa okunokuklwebheka okungashoni ngaphezulu, kugqitshwe izimbobo ezijulile, nama-engeli angaphansi kuka-20° ngendawo yokusebenza.

ukuhlolwa kwe-liquid penetrant
Isimiso esiyisisekelo sokuhlolwa kwe-liquid penetrant yukuthi ngemva kokuba ubuso bengxenye buboshwe ngamadayi e-fluorescent noma ama-colored dyes, i-penetrant ingangena ekungeneni kokuvula okungaphezulu ngaphansi kwesenzo se-capillary isikhathi esithile; ngemva kokukhipha ukungena okweqile ebusweni bengxenye, umthuthukisi we-A usetshenziswa ebusweni bengxenye.
Ngokufanayo, ngaphansi kwesenzo se-capillary, i-ejenti yokuthwebula izoheha uketshezi olungena ngaphakathi olugcinwe endaweni engalungile, futhi uketshezi olungena ngaphakathi luhlehlela emuva ku-ejenti yokuthwebula, futhi ngaphansi komthombo othile wokukhanya (ukukhanya kwe-ultraviolet noma ukukhanya okumhlophe), umkhondo we uketshezi olungenayo lapho kunesici luyaboniswa , (i-fluorescence ephuzi-luhlaza noma okubomvu okugqamile), ukuze kutholwe i-morphology nokusabalalisa amaphutha.
Izinzuzo zokuhlola ukungena yilezi:
1. Ingakwazi ukubona izinto ezihlukahlukene;
2. Ukuzwela okuphezulu;
3. Isibonisi esinembile, ukusebenza okulula kanye nezindleko zokutholwa eziphansi.
Ububi bokuhlolwa kokungena yilezi:
1. Ayifanelekile ukuhlola ama-workpieces enziwe ngezinto ezivulekile nezimbotshana zokusebenzela ezinezindawo ezimbi;
2. Ukuhlolwa kokungena kungathola kuphela ukusatshalaliswa okungaphezulu kweziphambeko, futhi kunzima ukunquma ukujula kwangempela kweziphambeko, ngakho-ke kunzima ukwenza ukuhlola kwenani kokukhubazeka. Umphumela wokutholwa nawo uthonywa kakhulu isisebenzisi.
Ukuhlolwa kwe-X-ray
Esokugcina, ukutholwa kwemisebe, kungenxa yokuthi ama-X-ray azolahleka ngemva kokudlula entweni ekhanyiswe, futhi izinto ezihlukene ezinogqinsi oluhlukene zinezilinganiso ezihlukene zokumunca kuzo, futhi ifilimu engeyinhle ibekwa ngakolunye uhlangothi lwento ekhanyiswe ngemisebe, okuzohluka ngenxa yokuqina kwe-ray ehlukene. Imidwebo ehambisanayo iyakhiqizwa, futhi ababuyekezi bangahlulela ukuthi kukhona yini ukukhubazeka ngaphakathi kwento kanye nemvelo yesici ngokusho kwesithombe.
Ukusebenza kanye nemikhawulo yokuhlolwa kwe-radiographic:
1. Izwela kakhulu ekutholweni kokukhubazeka kohlobo lwevolumu, futhi kulula ukuveza amaphutha.
2. I-radiographic negatives kulula ukuyigcina futhi ibe nokulandeleka.
3. Khombisa ngokubuka isimo kanye nohlobo lwamaphutha.
4. Okubi ukuthi ukujula okugqitshiwe kwesici akukwazi ukutholakala. Ngesikhathi esifanayo, ukushuba kokutholwa kukhawulelwe. Ifilimu engalungile idinga ukugezwa ngokukhethekile, futhi iyingozi emzimbeni womuntu, futhi izindleko ziphezulu.
Sekukonke, ukutholwa kwamaphutha nge-ultrasonic kanye ne-X-ray kulungele ukuthola amaphutha angaphakathi; phakathi kwazo, i-ultrasonic ifanele izingxenye ezinesimo esivamile esingaphezu kuka-5mm, futhi ama-X-ray awakwazi ukuthola ukujula kokungcwaba kokukhubazeka futhi abe nemisebe. Izinhlayiya zikaZibuthe kanye nokuhlolwa kwangaphakathi kulungele ukuthola ukukhubazeka kwezingxenye; phakathi kwazo, ukuhlolwa kwezinhlayiyana kazibuthe kunqunyelwe ekutholeni izinto zikazibuthe, futhi ukuhlola okungenayo kunqunyelwe ekutholeni amaphutha okuvuleka kwendawo.
