Surface Crack Ukutholwa UV: Qinisekisa izinga engenaphutha
Isingeniso se-Ultraviolet Surface Crack Detection
Ukuhlolwa kwanamuhla okungabhubhisi (i-NDT) kuncike kakhulu ekukhanyeni kwe-ultraviolet (UV) ekutholeni ukuqhekeka komhlaba. Le ndlela ivame ukubizwa ngokuthi i-Fluorescent Penetrant Inspection (FPI). Idlala indima ebalulekile ezimbonini eziphakeme kakhulu. Ngenxa yalokho, ngosizo lwe-UV yokuthola ukuqhekeka komhlaba, abahloli bangathola kalula ukukhubazeka okuncane ebusweni obungathinta ukuphepha nokusebenza kwezinto zokwakha.
Kuyini ukutholwa kwe-Surface Crack?
Ukutholwa kokuqhekeka komhlaba kubhekisela ekuboneni ukungahambi kahle okwenzeka ebusweni bezinto ezibonakalayo, okungaholela ekuhlulekeni uma kungatholakali. Lezi mifantu zingabangelwa amaphutha okukhiqiza, ukukhathala, ukugqwala, noma ezinye izingcindezi. Izindlela ezijwayelekile zingase zingaboni la maphutha ayinkimbinkimbi; Kodwa-ke, ngokusebenzisa amasu asuselwa ku-UV, ukuzwela kwabo kungathuthukiswa.
Indima yokukhanya kwe-UV ekutholeni ukuqhekeka
Isibonelo, ukukhanya kwe-ultraviolet, ikakhulukazi ukukhanya kwe-UV-A, kusiza ukuveza imifantu etholakala ebusweni. Ihlangana nokungena kwe-fluorescent njengedayi, ibenze babe yi-fluoresce, ngaleyo ndlela ibonise ukuba khona kwemifantu lapho ukungena okunjalo kungena khona. Iso lenyama lingabona ngisho nemifantu encane kakhulu ngenxa yale fluorescence.
Inqubo ye-Fluorescent Penetrant Inspection (FPI)
Ukulungiswa kwe-Surface: Konke okuqukethwe kuhlanzwa ngokuphelele ukuqeda noma yikuphi ukungcola kwezinto zangaphandle okungavimbela ukuhlolwa okufanele.
Ukusetshenziswa kwe-Penetrant: I-fluorescent penetrant isetshenziswa ebusweni. Lolu hlobo lwe-penetrant lunekhono lokungena emifantwini engaphezulu noma eduze komhlaba.
Isikhathi sokuhlala: I-penetrant ishiywa isikhathi esithile ukuze ifinyelele ezansi kwanoma yikuphi ukukhubazeka okutholakala ebusweni.
Ukususwa kwe-Penetrant Ngokweqile: Ngemuva kwesikhathi sayo sokuhlala, ukungena ngokweqile kuyasuswa, kushiya kuphela lokho kuvanjwe ngaphakathi kokuvuleka kwesici.
Isicelo sonjiniyela: Inqubo iqala ngokufaka isicelo sonjiniyela ebusweni. Lokhu kudonsa noma yikuphi ukungena okusele ngaphakathi kwalezi mifanuko, okwenza ukuthi zibonakale kakhudlwana.
Ukuhlolwa ngaphansi kokukhanya kwe-UV: Ukuhlola ubuso bengxenye ngemifantu engenzeka, ezobonakala ikhanya lapho ihlolwa ngaphansi kokukhanya kwe-UV-A
Ukuhlolwa: Izinkomba zihlolwa ukuze zifaneleke futhi zilinganise uhlobo nobukhulu bomonakalo we-crack (Johnston).
Kungani kuyingqayizivele?
I-UV100-N 365nm LED flashlight akuyona nje enye ithuluzi lokuhlola-kuyisixazululo esenzelwe ochwepheshe abakhulu embonini yokuhlola engabhubhisi (NDT). Yini eyenza ihluke yinhlanganisela ecatshangelwe yokusebenza, ukuqina, nokulula.
Ukuzwela
Imifantu encane, ukuqhekeka kwezinwele, namaphutha angaphezulu angase angabonakali ngezinye izindlela zokuhlola kungadalulwa ngokuhlolwa kwe-UV, ikakhulukazi kusetshenziswa ukuhlolwa kwe-fluorescent penetrant (FPI). Impendulo ekhazimulayo kusuka kudayi fluorescent ngaphansi 365nm UV ukukhanya kuzokwandisa ukukhubazeka ukubonakala ngisho ezindaweni eziyinkimbinkimbi.
Ukuhlolwa okusheshayo
Ukuqina okuphezulu kokukhipha kwe-15,000 μW / cm² kuvumela inkambu ebanzi yokubuka nokuskena okusheshayo lapho kuhlolwa izindawo ezinkulu noma eziningana ezincane. Isibonelo, isibani se-UV-A esinobubanzi bogongolo obufinyelela ku-100mm senza kube nokwenzeka ukuskena indawo enkulu ngaphandle kokwandisa isikhathi esichithwa ukuhlola indawo.
High Intensity
Indlela yokuthola i-UV crack iyabiza kakhulu uma iqhathaniswa namanye amasu e-NDT afana nokuhlolwa kwe-ultrasonic noma i-radiographic. Imishini, efana ne-UV100-N UV flashlight, ayigcini nje ngokuba nobungani bephakethe kodwa futhi ihlala isikhathi eside futhi inikeza ukusebenza okuhle isikhathi eside.
Izicelo Kuzo Zonke Izimboni
Aerospace
Embonini ye-aerospace, ubuqotho bezingxenye bubaluleke kakhulu. I-FPI isebenzisa ukukhanya kwe-UV ivumela ukuthola ngisho nemifantu encane ezingxenyeni zenjini, i-fuselage, nezinye izingxenye ezibalulekile, ngaleyo ndlela kulondoloze ukwehluleka okungenzeka.
Automotive
Ukutholwa kwe-UV kusetshenziswa ezinkampanini zokuqoqa izimoto ukuhlola amabhlogo enjini, i-chassis, phakathi kwezinye izinto eziqinisekisa ukuphepha nokwethenjelwa kwezimoto emgwaqeni.
Ukukhiqiza
Ngenkathi ukukhiqizwa, ikakhulukazi izinqubo zokuphonsa nokwakha, ukuhlonza kusenesikhathi ukukhubazeka komhlaba ngokuhlolwa kwe-UV kunciphisa amathuba emikhiqizo enesici engena emakethe.
Ungasebenzisa ukukhanya kwe-UV ukuhlola imifantu ebusweni ekuhlolweni kokhonkolo nesakhiwo, okungabeka engcupheni ubuqotho bezakhiwo nengqalasizinda.
Ukuthola imishini efanelekile ye-UV yokutholwa kwe-Surface Crack
Ukunemba, ukuphepha nokusebenza kahle kuncike kakhulu ekukhethweni okulungile kwemishini uma kukhulunywa ngokuthola imifantu ebusweni kusetshenziswa imisebe ye-UV. Ikhwalithi nokucaciswa kwezibani zakho ze-UV kunomthelela ngqo empumelelweni yokusebenza kwakho, noma ngabe wenza ukuhlolwa kwe-fluorescent penetrant (FPI) noma ukuhlolwa kwezinhlayiyana kazibuthe (MPI).
Izici ezibalulekile okufanele uzicabangele
UV-A Ukuqina
Imifantu nokukhubazeka kufanele kuboniswe ngokucacile ngezibani eziphezulu ze-ultraviolet-A. Amamodeli we-premium afana ne-UV100-N anamayunithi ahambisa kuze kufike ku-15,000 μW/cm², kanti amanye kufanele alethe okungenani u-5,000 μW/cm².
ukuphatheka
Uma uhlola esizeni, khona-ke ukuphatheka kuyadingeka. Izibani ze-UV ezingenantambo zinikeza abahloli inkululeko enkulu yokuhamba kungakhathalekile ukuthi basebenza ezungeze imishini eyinkimbinkimbi, izikhala eziqinile, noma izindawo ezikude.
Wavelength Ukunemba
Ngezinhlelo zokusebenza ze-NDT ne-FPI, ukukhanya kwakho kwe-ultra-violet kufanele kusebenza ngaphakathi kwebanga le-320-400 nm, yize ngaphakathi kwezinga lomkhakha, kungu-365 nm.
Battery Life
Inani lesikhathi sokuphumula elitholwe lincishisiwe ngempilo yebhethri ehlala isikhathi eside. Khetha amalambu anamabhethri ahlala phakathi kwamahora amane kuya kwayisithupha aqhubekayo, ikakhulukazi ngesikhathi somsebenzi wasensimini.
Industrial Durability
Imishini kufanele yenziwe nge-aluminium ye-anodized noma ezinye izinto ezingezona ezonakalisayo. Kufanele futhi ikwazi ukumelana nothuli, uwoyela, namazinga okushisa aphezulu.
Ukucatshangelwa Kwezokuphepha
Yize kungahlaseli, ukuhlolwa kwe-UV kudinga ukunakekelwa okuningi:
• Izingubo zokuzivikela: Njalo gqoka izibuko zokuphepha ezivimbela i-UV ukuvimbela ukulimala kwamehlo.
• Ukuvikelwa kwesikhumba: Nciphisa ukuvezwa kwesikhumba okuqondile futhi ugqoke imikhono emide noma amagilavu ngesikhathi sokusetshenziswa isikhathi eside.
• Ukuqeqeshwa: Qinisekisa ukuthi bonke abasebenzi baqeqeshwe kahle kumasu okuhlola i-UV futhi baqonde izivumelwano zokuphepha ze-UV.
Isiphetho
Ukutholwa kokuqhekeka komhlaba kubalulekile ekuqinisekiseni ubuqotho bezinto ezisetshenziswa ezimbonini ezahlukahlukene. Le ndlela isebenzisa izimiso ze-Fluorescent Penetrant Inspection (FPI), evumela ukuhlonza nokulungiswa okusheshayo ngisho nokungapheleli okuncane komhlaba. Ngemishini efanele nezinyathelo zokuphepha endaweni, lolu hlobo lokutholwa kwemifantu kusetshenziswa imisebe ye-ultraviolet lunikeza indlela engabizi futhi esebenzayo yokugcina ukuqina kwesakhiwo.
