Common X-ray Tube Failure Analysis
Kulephera 1: Kulephera kwa rotor yozungulira ya anode
(1) Zodabwitsa
① Dera ndi lachilendo, koma liwiro lozungulira limatsika kwambiri;nthawi yozungulira yokhazikika ndi yochepa;anode sazungulira panthawi yowonekera;
② Panthawi yowonekera, chubu chamakono chimawonjezeka kwambiri, ndipo fusesi yamagetsi imawombedwa;mfundo ina pa anode chandamale chandamale imasungunuka.
(2) Kusanthula
Pambuyo pogwira ntchito kwa nthawi yayitali, kuvala ndi kusinthika ndi kusintha kwa chilolezo kudzayambika, ndipo mawonekedwe a maselo a mafuta olimba adzasintha.
Mlandu 2: Malo omwe chandamale cha anode pa chubu cha X-ray chawonongeka
(1) Zodabwitsa
① Kutulutsa kwa X-ray kunachepa kwambiri, ndipo kukhudzidwa kwa filimu ya X-ray kunali kosakwanira;② Pamene chitsulo cha anode chinasungunuka kutentha kwakukulu, chitsulo chochepa kwambiri chikhoza kuwonedwa pa khoma la galasi;
③ Kudzera mu galasi lokulitsa, zitha kuwoneka kuti chandamalecho chili ndi ming'alu, ming'alu ndi kukokoloka, ndi zina zambiri.
④ Chitsulo cha tungsten chomwe chimaphwanyidwa chikasungunuka kwambiri chikhoza kuphulika ndikuwononga chubu cha X-ray.
(2) Kusanthula
① Kugwiritsa ntchito mochulukira.Pali zotheka ziwiri: imodzi ndikuti dera loteteza mochulukira limalephera kudzaza chiwonetsero chimodzi;chinacho chimakhala chowonekera kangapo, zomwe zimapangitsa kuti zichuluke mochulukira ndi kusungunuka ndi kutuluka;
② rotor ya chubu yozungulira ya anode X-ray imakakamira kapena chitetezo choyambira ndi cholakwika.Kuwonekera pamene anode sichizungulira kapena liwiro lozungulira ndilotsika kwambiri, zomwe zimapangitsa kusungunuka nthawi yomweyo ndi kutuluka kwa nthunzi ya chandamale cha anode;
③ Kutentha kosakwanira.Mwachitsanzo, kukhudzana pakati pa kutentha kwa kutentha ndi thupi la mkuwa la anode sikuyandikira mokwanira kapena pali mafuta ochulukirapo.
Cholakwika 3: X-ray chubu filament ndi yotseguka
(1) Zodabwitsa
① Palibe ma X-ray omwe amapangidwa panthawi yowonekera, ndipo mita ya milliamp ilibe chizindikiro;
② Ulusiwo suwunikiridwa kudzera pawindo la chubu la X-ray;
③ kuyeza ulusi wa X-ray chubu, ndipo mtengo kukana ndi wopandamalire.
(2) Kusanthula
① Magetsi a X-ray chubu filament ndi okwera kwambiri, ndipo ulusiwo umawomberedwa;
② Mlingo wa vacuum wa chubu cha X-ray umawonongeka, ndipo mpweya wochuluka wa mpweya umapangitsa kuti filament ikhale ndi okosijeni ndikuwotcha mwamsanga pambuyo popatsidwa mphamvu.
Mlandu 4: Palibe cholakwika ndi X-ray pojambula
(1) Zodabwitsa
① Kujambula sikutulutsa ma X-ray.
(2) Kusanthula
①Ngati palibe X-ray yopangidwa pojambula, nthawi zambiri weruzani kaye ngati magetsi okwera amatha kutumizidwa ku chubu nthawi zonse, ndikulumikiza chubu mwachindunji.
Ingoyezerani mphamvu yamagetsi.Tengani chitsanzo cha Beijing Wandong.Nthawi zambiri, chiŵerengero chamagetsi choyambirira ndi chachiwiri cha ma transfoma apamwamba kwambiri ndi 3:1000.Inde, tcherani khutu ku malo osungidwa ndi makina pasadakhale.Danga ili makamaka chifukwa cha kukana kwa mkati kwa magetsi, autotransformer, etc., ndi kutayika kumawonjezeka panthawi yowonekera, zomwe zimapangitsa kutsika kwa magetsi olowera, etc. Kutayika kumeneku kumagwirizana ndi kusankha kwa mA.Mphamvu yozindikira katundu iyeneranso kukhala yokwera.Choncho, ndi zachilendo pamene voteji yoyezedwa ndi ogwira ntchito yokonza iposa mtengo wapakati pa 3:1000.Mtengo wopitilira umagwirizana ndi kusankha kwa mA.Kukula kwa mA, kumakhalanso kokulirapo.Kuchokera pa izi, zikhoza kuweruzidwa ngati pali vuto ndi dera loyamba lamagetsi apamwamba.
