Ukuhlaziywa Kokwehluleka Kweshubhu Le-X-ray Evamile
Ukwehluleka 1: Ukwehluleka kwe-rotor ye-anode ejikelezayo
(1) Isenzakalo esingavamile
① Isekethe ijwayelekile, kodwa ijubane lokujikeleza lehla kakhulu; isikhathi sokujikeleza esingaguquki sifushane; i-anode ayijikelezi ngesikhathi sokuchayeka;
② Ngesikhathi sokuchayeka, umsinga wepayipi uyanda kakhulu, futhi i-fuse yamandla iyavunguzwa; iphuzu elithile ebusweni be-anode liyancibilika.
(2) Ukuhlaziywa
Ngemva komsebenzi wesikhathi eside, kuzobangelwa ukuguguleka nokuguquguquka kwamabhere kanye noshintsho lokuphuma kwesikhala, kanti nesakhiwo sama-molecule esithambisi esiqinile naso sizoshintsha.
Iphutha 2: Ubuso be-anode target ye-X-ray tube yonakele
(1) Isenzakalo esingavamile
① Ukukhishwa kwe-X-ray kwehle kakhulu, futhi ukuzwela kwefilimu ye-X-ray kwakwanele; ② Njengoba insimbi ye-anode yayihwamuka ekushiseni okuphezulu, ungqimba lwensimbi oluncane lungabonakala odongeni lwengilazi;
③ Ngengilazi yokukhulisa, kungabonakala ukuthi indawo okuqondiwe kuyo inemifantu, imifantu kanye nokuguguleka, njll.
④ I-tungsten yensimbi echitheka lapho i-focus incibilika kakhulu ingaqhuma futhi yonakalise ishubhu le-X-ray.
(2) Ukuhlaziywa
① Ukusetshenziswa kokulayisha ngokweqile. Kunezinto ezimbili ezingenzeka: eyodwa ukuthi isekethe yokuvikela ukulayisha ngokweqile yehluleka ukulayisha ngokweqile ukuvezwa okukodwa; enye ukuvezwa okuningi, okuholela ekugcwaleni ngokweqile okuhlanganisiwe nokuncibilika kanye nokuhwamuka;
② i-rotor ye-anode ejikelezayo i-X-ray tube ibambekile noma isekethe yokuvikela yokuqalisa inephutha. Ukuchayeka lapho i-anode ingajikelezi noma isivinini sokujikeleza siphansi kakhulu, okuholela ekuncibilikeni okusheshayo kanye nokuhwamuka kobuso be-anode;
③ Ukushabalalisa ukushisa okubi. Isibonelo, ukuthintana phakathi kwesinki yokushisa nomzimba wethusi we-anode akusondele ngokwanele noma kunamafutha amaningi kakhulu.
Iphutha 3: Intambo yeshubhu ye-X-ray ivulekile
(1) Isenzakalo esingavamile
① Akukho X-ray ekhiqizwayo ngesikhathi sokuchayeka, futhi i-milliamp meter ayinayo inkomba;
② Intambo ayikhanyiswa ngefasitela lepayipi le-X-ray;
③ Kala intambo yeshubhu le-X-ray, bese inani lokumelana lingenamkhawulo.
(2) Ukuhlaziywa
① I-voltage ye-filament ye-X-ray tube iphakeme kakhulu, futhi i-filament iyapheshulwa;
② Izinga le-vacuum le-X-ray tube liyabhujiswa, futhi inani elikhulu lomoya ongenayo libangela ukuthi i-filament i-oxidize futhi ishise ngokushesha ngemva kokunikezwa amandla.
Iphutha 4: Akukho phutha elibangelwa yi-X-ray ezithombeni
(1) Isenzakalo esingavamile
① Ukuthwebula izithombe akukhiqizi ama-X-ray.
(2) Ukuhlaziywa
①Uma kungekho X-ray ekhiqizwe esithombeni, ngokuvamile qala ukwahlulela ukuthi i-voltage ephezulu ingathunyelwa yini epayipini ngokujwayelekile, bese uxhuma ipayipi ngqo.
Kala nje i-voltage. Thatha i-Beijing Wandong njengesibonelo. Ngokuvamile, isilinganiso se-voltage esiyinhloko nesesibili sama-transformer ane-voltage ephezulu singu-3:1000. Vele, naka isikhala esigodliwe ngumshini kusengaphambili. Lesi sikhala sibangelwa kakhulu ukumelana kwangaphakathi kokunikezwa kwamandla, i-autotransformer, njll., futhi ukulahlekelwa kuyanda ngesikhathi sokuchayeka, okuholela ekwehleni kwe-voltage yokufaka, njll. Lokhu kulahlekelwa kuhlobene nokukhethwa kwe-mA. I-voltage yokuthola umthwalo kufanele futhi ibe phezulu. Ngakho-ke, kuvamile lapho i-voltage elinganiswa ngabasebenzi bokulungisa idlula inani ngaphakathi kobubanzi obuthile ngaphandle kuka-3:1000. Inani elidlulayo lihlobene nokukhethwa kwe-mA. Uma i-mA inkulu, inani liba likhulu. Kusukela kulokhu, kungahlulelwa ukuthi ngabe kukhona inkinga ngesekethe eyinhloko ene-voltage ephezulu.
