Uhlalutyo oluqhelekileyo lokungaphumeleli kwe-X-ray tube
Ukungaphumeleli kwe-1: Ukungaphumeleli kwe-rotor ye-anode ejikelezayo
(1) Isimanga
① Isekethe iqhelekile, kodwa isantya sokujikeleza siyehla kakhulu;ixesha lokujikeleza elisisigxina lifutshane;i-anode ayijikelezi ngexesha lokuvezwa;
② Ngexesha lokuvezwa, i-tube current iyanda ngokukhawuleza, kwaye i-fuse yamandla ivuthelwa;indawo ethile kwindawo ekujoliswe kuyo anode iyanyibilika.
(2) Uhlalutyo
Emva komsebenzi wexesha elide, i-bearing wear kunye ne-deformation kunye nokutshintshwa kwe-clearance kuya kubangelwa, kwaye isakhiwo se-molecular ye-lubricant eqinile iya kutshintsha.
Isiphoso sesi-2: Indawo ekujoliswe kuyo ye-anode yombhobho we-X-ray yonakaliswe
(1) Isimanga
① Ukukhutshwa kweX-reyi kwehle kakhulu, kwaye ubuntununtunu befilimu yeX-reyi babunganelanga;② Njengoko isinyithi se-anode sakhutshwa ngumphunga kwiqondo eliphezulu lobushushu, umaleko wesinyithi obhityileyo unokubonwa eludongeni lweglasi;
③ Ngokusebenzisa iglasi yokukhulisa, kunokubonwa ukuba indawo ekujoliswe kuyo ineentanda, iintanda kunye nokhukuliseko, njl.
④ I-tungsten yentsimbi etshiziweyo xa ugxininiso lunyibilike kakhulu lunokuthi lugqabhuke kwaye lonakalise ityhubhu ye-X-ray.
(2) Uhlalutyo
① Ukusetyenziswa ngokugqithisileyo.Kukho izinto ezimbini ezinokwenzeka: enye yeyokuba i-overload yokhuselo lwesekethe iyasilela ukulayisha ngaphezulu kokuvezwa okunye;enye kukutyhileka okuninzi, okukhokelela kumthwalo omninzi okhulayo kunye nokunyibilika kunye nokunyuka kwamanzi;
② i-rotor yetyhubhu ye-X-reyi ejikelezayo ibambekile okanye isekethe yokukhusela ukuqala iphosakele.Ukubonakaliswa xa i-anode ingaguquki okanye isantya sokujikeleza siphantsi kakhulu, okubangela ukunyibilika ngokukhawuleza kunye nokunyuka kwe-anode target surface;
③ Ukutshatyalaliswa kobushushu okulambathayo.Umzekelo, unxibelelwano phakathi kwe-heat sink kunye ne-anode yethusi yomzimba ayisondele ngokwaneleyo okanye kukho igrisi eninzi kakhulu.
Impazamo yesi-3: I-X-ray tube filament ivuliwe
(1) Isimanga
① Akukho mitha yeX-reyi iveliswayo ngexesha lokuvezwa, kwaye imitha yemiliamp ayinanto ebonisayo;
② Umcu awukhanyiswa ngefestile yetyhubhu yeX-reyi;
③ Ukulinganisa i-filament ye-X-ray ityhubhu, kwaye ixabiso lokuchasa alinasiphelo.
(2) Uhlalutyo
① Umbane wetyhubhu ye-X-ray iphezulu kakhulu, kwaye i-filament iyavuthelwa;
② Iqondo le-vacuum ye-tube ye-X-ray iyatshatyalaliswa, kwaye umthamo omkhulu wokungenisa umoya ubangela ukuba i-filament i-oxidize kwaye itshise ngokukhawuleza emva kokuba inikwe amandla.
Impazamo yesi-4: Akukho mpazamo ibangelwa yiX-reyi kwifoto
(1) Isimanga
① Ukufota akuvelisi imitha yeX-reyi.
(2) Uhlalutyo
① Ukuba akukho X-ray iveliswayo kwifoto, jonga kuqala ukuba ingaba amandla ombane aphezulu angathunyelwa kumbhobho ngokuqhelekileyo, kwaye uqhagamshele ngqo ityhubhu.
Ukulinganisa nje umbane.Thatha iBeijing Wandong njengomzekelo.Ngokubanzi, umlinganiselo wombane ophambili kunye nowesibini we-high-voltage transformers yi-3: 1000.Ngokuqinisekileyo, nikela ingqalelo kwindawo egcinwe ngumatshini kwangaphambili.Esi sithuba ikakhulu ngenxa yokuchasana kwangaphakathi kombane, i-autotransformer, njl., kwaye ilahleko iyanda ngexesha lokuvezwa, okubangelwa ukuhla kwe-voltage yegalelo, njl. Le lahleko ihambelana nokukhethwa kwe-mA.Umbane wokubona umthwalo nawo kufuneka ube phezulu.Ngoko ke, kuqhelekile xa i-voltage elinganiswe ngabasebenzi bolondolozo idlula ixabiso phakathi koluhlu oluthile ngaphandle kwe-3: 1000.Ixabiso eligqithileyo linxulumene nokukhethwa kwe-ma.Inkulu i-mA, ixabiso elikhulu.Ukusuka kule nto, inokugwetywa ukuba kukho ingxaki kunye nesiphaluka esiphezulu se-high-voltage.
