Yuav ua li cas yog tias lub rhaub hluav taws xob ntawm cov tshuaj tiv thaiv hluav taws xob xau

Dab tsi yog vim li cas rau qhov to ntawm lub reactor hluav taws xob rhaub? Niaj hnub no, cia peb txheeb xyuas cov laj thawj hauv kev nthuav dav. Rau lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob hluav taws xob, nws kuj tuaj yeem siv los ua cov khoom siv. Cov hauv qab no yuav raug txheeb xyuas, tshwj xeeb raws li hauv qab no:
Lub to ntawm lub reactor hluav taws xob rhaub yog feem ntau xav txog nyob rau hauv ob yam: ib tug yog lub to ntawm cov yeeb nkab chaw nres nkoj, thiab lwm yam yog lub to ntawm cov yeeb nkab nws tus kheej.
1. Cov dej ntws tawm ntawm qhov chaw nres nkoj yeeb nkab
Yog vim li cas 1: Ntau dhau thermal stress
Thaum lub sijhawm pib thiab kaw cov txheej txheem ntawm lub tshuab hluav taws xob reactor, yog tias qhov kub thiab txias poob qis tshaj li qhov teev tseg, nws yuav ua rau muaj kev ntxhov siab ntawm cov kav dej thiab cov phaj, ua rau kev puas tsuaj rau cov welds lossis expansion pob qij txha, thiab yog li ua rau qhov chaw nres nkoj to.
Yog vim li cas 2: Tube phaj deformation
Yog hais tias lub raj phaj dhau deformation, cov dej xau yuav tshwm sim thaum nws txuas nrog cov yeeb nkab, thiab qhov tuab tsis txaus ntawm lub phaj phaj yog ib qho laj thawj rau deformation ntawm lub raj phaj.
Yog vim li cas 3: Cov txheej txheem tsis zoo ntawm cov yeeb nkab ntsaws
Feem ntau, lub conical plug yog siv los vuam thiab ntsaws cov yeeb nkab. Thaum ntxig lub conical ntsaws, lub zog yuav tsum yog nruab nrab, vim tias lub zog ntau dhau tuaj yeem ua rau deformation ntawm cov yeeb nkab qhov. Thaum lub sij hawm vuam txheej txheem, kev ua haujlwm tsis raug lossis txoj haujlwm tsis raug thiab qhov loj me tuaj yeem ua rau kev sib txuas ntawm cov yeeb nkab thiab lub phaj phaj.
2. Cov yeeb nkab nws tus kheej xau
Yog vim li cas 1: yaig thiab yaig
Cov dej ntws nrawm nrawm yog qhov siab, thiab muaj cov kab dej loj loj hauv cov dej ntws. Lub sijhawm no, cov phab ntsa sab nrauv ntawm cov yeeb nkab yuav raug ntxuav tawm los ntawm ob-theem ntws ntawm chav dej thiab dej, ua rau nyias nyias ntawm cov yeeb nkab phab ntsa, perforation, los yog raug nyem tawm thaum raug dej.
Vim yog cov khoom siv tsis tsim nyog thiab kho cov txheej txheem ntawm kev tiv thaiv kev cuam tshuam phaj, nws yuav tawg lossis poob vim qhov cuam tshuam los ntawm cov pa lossis hydrophobic, yog li poob nws cov txiaj ntsig tiv thaiv. Lub cheeb tsam ntawm lub phaj tiv thaiv tsis loj txaus, thiab qhov kev ncua deb ntawm lub plhaub thiab lub raj ntim khoom me me dhau, uas yog vim li cas.
Yog vim li cas 2: yeeb nkab vibration
Thaum lub raj ntim vibrates, yog tias qhov kev vibration zaus lossis nws qhov ntau yog tib yam li qhov zaus ntawm lub zog excitation, resonance yuav tshwm sim, ua rau muaj kev nce hauv amplitude thiab thaum kawg ua rau kev puas tsuaj rau kev sib txuas ntawm lub raj thiab lub raj phaj.
Yog vim li cas 3: Corrosion
Thaum cov khoom siv yeeb nkab ntawm cov tshuaj tiv thaiv hluav taws xob hluav taws xob yog tooj liab, yog tias tus nqi pH siab dhau lawm, nws yuav ua rau corrosion ntawm cov yeeb nkab tooj liab thiab ua rau to.
Yog vim li cas 4: Cov khoom siv tsis zoo thiab kev ua haujlwm zoo
Nrog rau cov khoom siv yeeb nkab tsis zoo, cov phab ntsa tuab tsis sib xws, qhov tsis xws ntawm cov yeeb nkab, thiab kev nthuav dav ntau dhau ntawm kev sib koom ua ke, cov no yog tag nrho cov kev tshwm sim ntawm cov khoom tsis zoo thiab cov txheej txheem. Thaum lub tshuab hluav taws xob hluav taws xob ntawm cov tshuaj tiv thaiv hluav taws xob ntsib cov xwm txheej txawv txav, nws yooj yim rau kev puas tsuaj rau cov kav dej thiab ua rau kom tawg.
