Nazari gama gari na Tube X-ray Failure Analysis
Kasawa ta 1: gazawar na'urar rotor na anode mai jujjuyawa
(1) Al'amari
① Da'irar al'ada ce, amma saurin juyawa ya ragu sosai;lokacin juyawa a tsaye gajere ne;anode ba ya jujjuya yayin bayyanarwa;
② Yayin da ake nunawa, bututu na yanzu yana ƙaruwa sosai, kuma ana busa fis ɗin wutar lantarki;wani batu a kan anode manufa surface an narke.

Bayan aiki na dogon lokaci, za a haifar da lalacewa da lalacewa da kuma canjin sharewa, kuma tsarin kwayoyin halitta na mai mai mai ƙarfi shima zai canza.
Laifi 2: Wurin da aka nufa na anode na bututun X-ray ya lalace
(1) Al'amari
① Sakamakon X-ray ya ragu sosai, kuma hankalin fim din X-ray bai isa ba;② Kamar yadda ƙarfen anode ya ƙafe a babban zafin jiki, ana iya ganin ƙaramin ƙarfe na bakin ciki akan bangon gilashi;
③ Ta hanyar gilashin ƙara girma, ana iya ganin cewa abin da ake nufi yana da tsagewa, tsagewa da yashwa, da dai sauransu.
④ Tungsten karfen da ya fantsama lokacin da aka narke sosai na iya fashe kuma ya lalata bututun X-ray.

① Yin amfani da wuce gona da iri.Akwai yuwuwa guda biyu: ɗaya shine cewa da'irar kariyar overload ta kasa cika ɗaukar nauyi ɗaya;ɗayan kuma shi ne bayyanar da yawa, wanda ke haifar da tarawa da yawa da narkewa da ƙazantawa;
② rotor na bututun X-ray na anode mai jujjuya yana makale ko da'irar kariyar farawa ta yi kuskure.Bayyanawa lokacin da anode baya juyawa ko saurin jujjuyawar ya yi ƙasa da ƙasa, yana haifar da narkewa nan take da ƙafewar saman manufa ta anode;
③ Rashin ƙarancin zafi.Misali, tuntuɓar da ke tsakanin ɗumbin zafin rana da jikin jan ƙarfe na anode bai kusa isa ko akwai mai mai yawa ba.
Laifi na 3: Filayen bututun X-ray a buɗe yake
(1) Al'amari
① Babu haskoki na X da aka haifar a yayin da ake nunawa, kuma mita milliamp ba shi da wata alama;
② Ba a kunna filament ta taga na bututun X-ray;
③ Auna filament na bututun X-ray, kuma ƙimar juriya ba ta da iyaka.
(2) Nazari
① Wutar lantarki na filament tube na X-ray ya yi yawa, kuma ana busa filament;
② Matsakaicin matakin bututun X-ray ya lalace, kuma yawan iskar da ake amfani da shi yana haifar da filament don yin oxidize kuma ya ƙone da sauri bayan an ƙarfafa shi.
Laifi na 4: Babu laifi da X-ray ya haifar a daukar hoto
(1) Al'amari
① Hoto baya haifar da haskoki na X-ray.
(2) Nazari
①Idan babu X-ray da aka samar a cikin daukar hoto, gabaɗaya da farko yanke hukunci ko za'a iya aika babban ƙarfin lantarki zuwa bututu akai-akai, kuma kai tsaye haɗa bututun.
Kawai auna ƙarfin lantarki.Dauki Beijing Wandong a matsayin misali.Gabaɗaya, rabon wutar lantarki na farko da na biyu na manyan injinan wutan lantarki shine 3:1000.Tabbas, kula da sararin da na'urar ta tanada a gaba.Wannan sarari ya fi dacewa saboda juriya na ciki na wutar lantarki, autotransformer, da dai sauransu, kuma asarar yana ƙaruwa yayin da ake nunawa, yana haifar da raguwa a cikin ƙarfin shigarwa, da dai sauransu. Wannan asarar yana da alaƙa da zaɓi na mA.Har ila yau, ƙarfin gano kaya ya kamata ya zama mafi girma.Saboda haka, yana da al'ada lokacin da ƙarfin lantarki da ma'aikatan kulawa suka auna ya wuce ƙimar da ke cikin wani kewayon ban da 3:1000.Ƙimar da ta wuce gona da iri tana da alaƙa da zaɓin mA.Mafi girma mA, mafi girma darajar.Daga wannan, ana iya yin hukunci ko akwai matsala tare da babban ƙarfin lantarki na farko.
