Amasu Okuthola Amaphutha Ensimbi: Ukubaluleka Kokunemba Nokuphepha Embonini
Ukutholwa kwamaphutha ensimbi kuyisici esibalulekile sezimboni ezahlukahlukene ezithembele ekusebenzeni kwezinto ukuze kuphephe futhi kusebenze kahle. Kusukela ezindizeni kuya ezimotweni kuya engqalasizinda, ulwazi oluningiliziwe ngezimo zensimbi lungavimbela izingozi, ukuwohloka okungahleliwe, futhi lunciphise izindleko. Lesi sihloko sizoxoxa ngamanye amasu abalulekile okutholwa kwamaphutha ensimbi kanye nokubaluleka kokusebenzisa lobu buchwepheshe ukuqinisekisa ukunemba nokuphepha.
Izindlela Zokubona Nokuhlola Okubonakalayo Ukusebenzisa Amathuluzi
Indlela yokuqala nelula kodwa ephumelela kakhulu yindlela yokubona. Ukuhlola okubonakalayo kungenziwa uchwepheshe oqeqeshiwe esebenzisa isikhulisi noma olunye usizo lokubona ukuze kutholakale amaphutha angaphezulu njengokuqhekeka, imihuzuko, kanye nokugqwala. Empeleni, le ndlela ingaveza izimpawu zezinkinga futhi idinga uphenyo olwengeziwe ukuze kutholakale okutholakele okujulile.
Izindlela ezibonakalayo zingathuthukiswa ngokusebenzisa ubuchwepheshe obufana nama-microscope, ama-endoscope, namakhamera anesinqumo esiphezulu axhunywe kwisofthiwe yokuhlaziya izithombe. Lawa masu ngokuvamile anqunyelwe ekuhlolweni kwendawo futhi kunzima ukubona amaphutha angaphakathi.
Ukuhlolwa Okungonakalisi (NDT)
Ukuhlolwa Kwe-X-Ray (i-X-Ray kanye ne-Gamma Ray)
Ukuhlolwa kwe-X-ray kusebenzisa imisebe ye-X noma ye-gamma ukuze kungene ngale kobuso bensimbi futhi kutholakale amaphutha angaphakathi. Isithombe se-radiographic (ifilimu noma sedijithali) senzelwe ukuveza umehluko wobuningi ngaphakathi kwensimbi, okubonisa ukugoba, imifantu, noma ukufakwa (izinhlayiya zangaphandle ngaphakathi kwensimbi). Le ndlela iwusizo kakhulu ezimbonini ezifana nezindiza, lapho ukuphepha kuyinto eza kuqala khona. Naphezu kwezindleko eziphakeme kanye nesidingo sendawo ephephile ekushiseni, ukuhlolwa kwe-radiographic kunikeza imiphumela enembile kakhulu nenemininingwane.
Ukuhlolwa kwe-Ultrasonic
Ukuhlolwa kwe-Ultrasonic kusebenzisa amaza omsindo avame kakhulu ukuthola amaphutha ensimbi. Ithuluzi lithumela amaza omsindo ezintweni, abese ebonakala emuva uma kukhona amaphutha. Isikhathi sokubuya kanye namandla amaza abonakalayo kuyahlaziywa ukuze kutholakale indawo nosayizi wamaphutha. Le ndlela isebenza kahle ekutholeni imifantu, ukuhlukanisa, kanye nokunye ukungahambi kahle kwesakhiwo sangaphakathi. I-Ultrasound isebenza kahle kakhulu ezintweni ezijiyile futhi ingasetshenziswa ensimini ngaphandle kokudinga ukuvikelwa kwemisebe.
Ukuhlolwa Kwezinhlayiya ZikaMagnetic
Ukuhlolwa kwezinhlayiya ze-magnetic (MPI) kusetshenziswa ezinsimbini ze-ferromagnetic. Insimbi inamandla kazibuthe, futhi izinhlayiya zensimbi ezincane kakhulu zisakazwa phezu kobuso bayo. Lezi zinhlayiya zizoqongelela eduze kweziphambeko zobuso noma ngaphakathi eduze kobuso njengoba insimu kazibuthe edalwa ukuba khona kwazo ishintsha. Iziphambeko ezifana nokuqhekeka kanye nokuvuleka kwe-porosity kungatholakala kalula ngokuqongelela kwezinhlayiya zensimbi. I-MPI iyindlela esheshayo futhi engabizi kakhulu evame ukusetshenziswa ekuhlolweni kokuqala kanye nokugcinwa njalo.
Ukuhlolwa Kokungena Koketshezi
Ukuhlolwa kokungena koketshezi kuyindlela elula kodwa ephumelelayo esetshenziselwa ukuthola amaphutha ebusweni njengemifantu emincane noma ukubhoboka okungabonakali emehlweni enyama. Insimbi ihlanzwa kuqala bese igcotshwa nge-liquid penetrant enombala okhanyayo noma ekhanyayo. Ngemva kwesikhathi esithile, uketshezi luyasulwa ebusweni, bese indawo esele igcotshwa ngesendlalelo sonjiniyela esidonsa i-penetrant emuva emigodini emincane. Iphutha litholakala lapho i-penetrant ebusweni ibonakala ngokucacile ngesendlalelo sonjiniyela. Le ndlela ivame ukusetshenziswa ukuhlola izinsimbi ezenziwe njengezingxenye ezihlanganisiwe.
Amasu Okuhlola Okubhubhisayo
Ngaphezu kokuhlola okungabhubhisi, ukuhlolwa okubhubhisayo kungenziwa futhi ukuze kutholakale ulwazi olujulile mayelana nezici zezinto ezibonakalayo.
Ukuhlolwa Kokunamathela
Ukuhlolwa kokudonsa kuhilela ukuhlola into ecindezelwe kuze kufike endaweni yokuphuka ukuze kutholakale amandla ayo aphezulu okudonsa, ukunwebeka, kanye nendawo yokuphuka kwezinto. Imiphumela yokuhlolwa kokudonsa ingabonisa amandla kanye nokuqina kwensimbi evivinywayo, ngaleyo ndlela kutholakale noma yiziphi iziphambeko ezingathinta ubuqotho besakhiwo sayo.
Ukuhlolwa Kokuqina
Ukuhlolwa kokuqina kusebenzisa ukugoba (ingcindezi) ebusweni bensimbi ukuze kutholakale ubulukhuni bento. Izindlela ezifana noBrinell, Rockwell, kanye noVickers zingaveza umehluko ebulukhunini ngenxa yokwehluka kokwakheka kwezinto noma amaphutha afana nokuhlukanisa noma ezinye izindawo zobuthakathaka.
Ukuhlolwa Kokuqina
Ukuhlolwa kokuqina, njengokuhlolwa kwe-Charpy noma i-Izod, kunikeza ulwazi mayelana nezakhiwo zomthelela wento ngokusebenzisa umthwalo wokushaqeka. Le miphumela yokuhlolwa yembula ukumelana kwensimbi ekuguqukeni okungazelelwe, okubalulekile ekusetshenzisweni okudinga ukuqina okuphezulu.
Izinzuzo kanye Nezinselele Ekusebenziseni Amasu Okuthola Amaphutha
Ukusetshenziswa kwamasu okuthola amaphutha ezinsimbini, kokubili i-NDT kanye nokuhlolwa okubhubhisayo, kunikeza izinzuzo eziningi embonini. Izinzuzo eziyinhloko ukunciphisa ingozi yokwehluleka kwesakhiwo, ukwandisa impilo yesevisi yezinto ezibonakalayo, kanye nokonga izindleko zesikhathi eside ngokuthola izinkinga isikhathi eside ngaphambi kokuba zibe zimbi kakhulu. Ngaphezu kwalokho, lawa masu asiza ukuhlangabezana namazinga okuphepha embonini kanye nekhwalithi, okukhulisa ukuzethemba kwabathengi kanye nababambiqhaza.
Kodwa-ke, inqubo ngayinye inezinselele ezinkulu. Isibonelo, izindleko eziphezulu zemishini yokuhlola nge-x-ray kanye ne-ultrasound kanye nokusebenza, noma ukulinganiselwa kwezindlela zezinhlayiya zamagnetic ezinsimbi ezingezona eze-ferromagnetic. Ukukhetha inqubo efanele kakhulu kuvame ukudinga ukuqonda okuphelele kwezidingo ezithile zokusetshenziswa kanye nokuhambisana nezindinganiso zemboni.
Isiphetho
Ezweni lezimboni eliyinkimbinkimbi elidinga amazinga aphezulu okusebenza nokuphepha, amasu okuthola amaphutha ezinsimbini ayisici esibalulekile sokuphathwa kwekhwalithi nokuqina kwezinto. Izindlela ezahlukahlukene, kufaka phakathi ezibonakalayo, i-NDT, kanye nezokubhubhisa, zinikeza izinketho ezibalulekile zokuqinisekisa ubuqotho bezinto nokugwema izingozi ezingase zibize kakhulu.
Njengoba ubuchwepheshe buqhubeka nokuthuthuka, lawa masu aya ngokuya eba yinkimbinkimbi futhi enembile, esekela imikhuba yezimboni ephephile futhi esebenza kahle. Ukuqonda amandla kanye nemikhawulo yendlela ngayinye, kanye nokusebenzisa indlela ehlanganisiwe, kuzoqinisekisa ukuthi izinsimbi ezisetshenziswa kuhlelo ngalunye zihlolwa ngokucophelela futhi zithembekile, okusekela imisebenzi yezimboni ephumelelayo.
