Ⅰ.Kuyini ukuhlola okungabhubhisi?
Ngokuvamile, ukuhlola okungonakali kusebenzisa izici zomsindo, ukukhanya, ugesi kanye nezibuthe ukuze kutholwe indawo, usayizi, ubuningi, imvelo kanye nolunye ulwazi oluhlobene lokunamaphutha okuseduze noma kwangaphakathi ebusweni bento ngaphandle kokulimaza impahla ngokwayo. .Ukuhlola okungabhubhisi kuhloswe ukuthola isimo sobuchwepheshe sezinto ezisetshenziswayo, okuhlanganisa ukuthi zifanelekile yini noma zisele nempilo yesevisi, ngaphandle kokuthikameza ukusebenza kwesikhathi esizayo kwezinto zokwakha.Izindlela zokuhlola ezivamile ezingabhubhisi zihlanganisa ukuhlolwa kwe-ultrasonic, ukuhlolwa kwe-electromagnetic, kanye nozibuthe. ukuhlolwa kwezinhlayiyana, phakathi kwazo Ukuhlolwa kwe-Ultrasonic kungenye yezindlela ezisetshenziswa kakhulu.
Ⅱ.Izindlela ezinhlanu ezijwayelekile zokuhlola ezingalimazi:
Ukuhlolwa kwe-Ultrasonic kuyindlela esebenzisa izici zamaza e-ultrasonic ukuze asakaze futhi abonise ezintweni ukuze kutholwe ukukhubazeka kwangaphakathi noma izinto zangaphandle ezintweni ezibonakalayo. Ingakwazi ukubona ukukhubazeka okuhlukahlukene, njengokuqhekeka, ama-pores, inclusions, looseness, njll. Ukutholwa kwamaphutha e-Ultrasonic kulungele izinto ezihlukahlukene, futhi kungakwazi ukubona ukushuba kwezinto, njengezinsimbi, okungezona izinsimbi, izinto eziyinhlanganisela, njll. ingenye yezindlela ezisetshenziswa kakhulu ekuhloleni okungabhubhisi.
Kungani amapuleti ensimbi awugqinsi, amapayipi anezindonga eziwugqinsi kanye nezinsimbi eziyindilinga ezinobubanzi obukhulu zifaneleka kakhulu ukuhlolwa kwe-UT?
① Uma ubukhulu bento bukhulu, amathuba okuba khona kokukhubazeka kwangaphakathi okufana nezimbotshana nokuqhekeka kuzokwanda ngokufanele.
②Ama-Forging akhiqizwa ngenqubo yokubumba, engase ibangele ukukhubazeka okufana nezimbotshana, ukufakwa, kanye nemifantu ngaphakathi kwento.
③Amapayipi anezindonga eziwugqinsi nezinduku eziyindilinga ezinobubanzi obukhulu zivame ukusetshenziswa ekudaleni izakhiwo zobunjiniyela noma izimo ezithwala ingcindezi ephezulu. Ukuhlolwa kwe-UT kungangena kujule kokubalulekile futhi kuthole okungaba khona amaphutha angaphakathi, njengokuqhekeka, okokufaka, njll., okubalulekile ekuqinisekiseni ubuqotho nokuphepha kwesakhiwo.
2.IPENETRANT TEST incazelo
Izimo ezisebenzayo zokuhlolwa kwe-UT kanye nokuhlolwa kwe-PT
Ukuhlolwa kwe-UT kulungele ukuthola amaphutha angaphakathi ezinto ezisetshenziswayo, njengezimbotshana, izimbotshana, imifantu, njll. Ukuhlolwa kwe-UT kungangena kugqinsi lempahla futhi kubone amaphutha ngaphakathi kokubalulekile ngokukhipha amagagasi e-ultrasonic nokuthola amasignali abonisiwe.
Ukuhlolwa kwe-PT kulungele ukuthola ukonakala ebusweni bezinto ezibonakalayo, njengezimbotshana, okufakiwe, imifantu, njll. Ukuhlolwa kwe-PT kuncike ekungeneni koketshezi emifantwini noma emaphethini futhi kusebenzisa umthuthukisi wombala ukuze abonise indawo nokuma kokukhubazeka.
Ukuhlolwa kwe-UT kanye nokuhlolwa kwe-PT kunezinzuzo zako kanye nokubi ezinhlelweni ezisebenzayo. Khetha indlela yokuhlola efanele ngokuya ngezidingo zokuhlola ezihlukene kanye nezici ezibonakalayo ukuze uthole imiphumela engcono yokuhlola.
3.Eddy Ukuhlolwa Kwamanje
(1) Isingeniso sokuhlolwa kwe-ET
I-ET Test isebenzisa umgomo wokungeniswa kwe-electromagnetic ukuletha ikhoyili yokuhlola eshintshanayo ephethe njengamanje eduze kwe-conductor workpiece ukuze ikhiqize ama-eddy currents. Ngokusekelwe ezinguqukweni zama-eddy currents, izakhiwo kanye nesimo se-workpiece kungachazwa.
(2) Izinzuzo zokuhlolwa kwe-ET
Ukuhlolwa kwe-ET akudingi ukuthintana ne-workpiece noma i-medium, isivinini sokuthola siyashesha kakhulu, futhi singahlola izinto ezingezona ezensimbi ezingaheha imisinga eddy, njengegraphite.
(3) Imikhawulo yokuhlolwa kwe-ET
Ingabona kuphela ukonakala okungaphezulu kwezinto ezisetshenziswayo. Uma usebenzisa ikhoyili yohlobo lwe- through-type ye-ET, akunakwenzeka ukucacisa indawo ethile yesici kusiyingi.
(4) Izindleko nezinzuzo
I-ET Test inemishini elula nokusebenza okulula. Akudingi ukuqeqeshwa okuyinkimbinkimbi futhi ingenza ngokushesha ukuhlola kwesikhathi sangempela esizeni.
Isimiso esiyisisekelo sokuhlolwa kwe-PT: ngemva kokuba ubuso bengxenye buhlanganiswe nodayi we-fluorescent noma udayi onemibala, i-penetrant ingangena emaphutheni okuvula ebusweni ngaphansi kwenkathi yesenzo se-capillary; ngemva kokukhipha ukungena okweqile ebusweni bengxenye, ingxenye ingaba Faka unjiniyela ebusweni. Ngokufanayo, ngaphansi kwesenzo se-capillary, umthuthukisi uzoheha i-penetrant egcinwe enenkinga, futhi i-penetrant izongena ibuyele kunjiniyela. Ngaphansi komthombo othile wokukhanya (ukukhanya kwe-ultraviolet noma ukukhanya okumhlophe), amathrekhi okungena lapho kunesici azoboniswa khona. , (i-fluorescence ephuzi-luhlaza noma okubomvu ngokugqamile), ngaleyo ndlela ithola ukumila nokusatshalaliswa kweziphambeko.
4.Magnetic Particle Testing
I-Magnetic Particle Testing" iyindlela yokuhlola evame ukusetshenziswa engangonakali ukuze kutholwe ukonakala kwendawo kanye naseduze kobuso ezintweni ezisetshenziswayo, ikakhulukazi ukuthola imifantu. Isekelwe ekuphenduleni okuyingqayizivele kwezinhlayiya kazibuthe kuzindawo kazibuthe, okuvumela ukutholwa ngempumelelo amaphutha angaphansi komhlaba.
5.I-RADIOGRAPHIC TEST
(1) Isingeniso sokuhlolwa kwe-RT
Ama-X-ray amagagasi kagesi anefrikhwensi ephezulu kakhulu, ubude begagasi obufushane kakhulu, namandla aphezulu. Bangakwazi ukungena ezintweni ezingenakungena ukukhanya okubonakalayo, futhi babhekane nokusabela okuyinkimbinkimbi ngezinto ngesikhathi senqubo yokungena.
(2) Izinzuzo zokuhlolwa kwe-RT
Ukuhlolwa kwe-RT kungasetshenziswa ukuthola ukukhubazeka kwangaphakathi kwezinto, njengezimbotshana, ukuqhekeka kokufakwa, njll., futhi kungasetshenziswa ukuhlola ubuqotho besakhiwo kanye nekhwalithi yangaphakathi yezinto.
(3) Umgomo wokuhlolwa kwe-RT
Ukuhlolwa kwe-RT kuthola ukukhubazeka ngaphakathi kokokusebenza ngokukhipha ama-X-ray nokuthola amasignali abonisiwe. Ngezinto eziwugqinsi, ukuhlolwa kwe-UT kuyindlela esebenzayo.
(4) Imikhawulo yokuhlolwa kwe-RT
Ukuhlolwa kwe-RT kunemikhawulo ethile. Ngenxa yobude bayo nezici zamandla, ama-X-ray awakwazi ukungena ezintweni ezithile, njengomthofu, insimbi, insimbi engagqwali, njll.
