Vim li cas Leak -tightness tseem ceeb rau Hydrogen Coolers?
Leak- nruj yog ib qho tseem ceeb rau hydrogen coolers vim hais tias txawm me me heev leaks tuaj yeem tsim kev nyab xeeb loj, kev ua haujlwm, thiab kev cia siab rau hauv hydrogen- cov tshuab hluav taws xob txias.
Kev Nyab Xeeb Risk ntawm Hydrogen Leakage
Hydrogen yog cov nplaim taws heev thiab muaj ntau yam tawg thaum sib xyaw nrog huab cua. Ib qho xau hauv lub tshuab hluav taws xob tuaj yeem tso cai rau hydrogen khiav mus rau hauv lub tshuab hluav taws xob lub tshuab hluav taws xob lossis lub tshuab hluav taws xob, qhov chaw uas nws tuaj yeem tsim cov khoom tawg. Vim tias hydrogen molecules me me heev, lawv tuaj yeem khiav los ntawm cov teeb meem me me uas yuav tsis cuam tshuam rau lwm cov pa roj.
Risk ntawm dej Ingress mus rau hauv lub Generator
Feem ntau lub tshuab hluav taws xob hydrogen coolers yog hydrogen - mus rau - dej kub exchangers. Yog hais tias ib qho dej ntws tawm ntawm lub raj sab:
Cov dej txias tuaj yeem nkag mus rau hauv hydrogen circuit
Cov dej noo tuaj yeem ncav cuag stator windings thiab rwb thaiv tsev
Hluav taws xob rwb thaiv tsev degradation, luv Circuit Court, los yog av txhaum tej zaum yuav tshwm sim
Dej ingress yog ib hom kev ua tsis tau zoo tshaj plaws rau cov tshuab hluav taws xob loj.
Kev cuam tshuam rau Generator Performance
Hydrogen siab thiab purity yog qhov tseem ceeb rau kev ua kom txias. Leaks tuaj yeem:
Txo hydrogen siab, txo cov cua txias efficiency
Ua kom lub zog poob thiab ua haujlwm kub
Force generator derating lossis kaw
Kev tuav lub kaw lus hydrogen kom ruaj khov thermal ua haujlwm.
Corrosion thiab Long -Kev puas tsuaj rau lub sijhawm
Cov dej xau tsis pom tuaj tuaj yeem qhia cov pa oxygen thiab noo noo, ua rau:
Internal corrosion ntawm generator Cheebtsam
Degradation ntawm cov tub yees txias thiab headers
Txo kev pab cuam lub neej ntawm ob qho tib si txias thiab lub tshuab hluav taws xob
Kev tswj hwm thiab OEM xav tau
Lub tshuab hluav taws xob hydrogen coolers yuav raug xau nruj heev- cov qauv nruj tau hais los ntawm:
IEC thiab IEEE generator specifications
OEM cov cai (GE, Siemens, Mitsubishi, thiab lwm yam)
Kev ntsuas siab thiab helium leak test raws tu qauv
Cov qauv no muaj nyob vim tias qhov tshwm sim ntawm kev xau yog qhov hnyav.
Cov ntsiab lus
Leak- nruj hauv hydrogen coolers yog qhov tseem ceeb rau:
Tiv thaiv hluav taws thiab tawg phom sij
Tsis txhob muaj dej ingress thiab rwb thaiv tsev puas
Tswj lub tshuab hluav taws xob efficiency thiab tso zis
Ua kom muaj kev nyab xeeb, ua haujlwm ntev -, thiab txhim khu kev qha
Rau hydrogen-cov tshuab hluav taws xob txias, xau- nruj tsis yog qhov kev nyiam tsim- nws yog qhov tseem ceeb ntawm kev nyab xeeb thiab kev ua tau zoo.
