Lub hauv paus ntsiab lus ntawm kev kub ceev loading caj npab yog raws li nram no:
low-temperature loading arm, tseem hu ua cryogenic loading caj npab, yog tsim los rau kev nyab xeeb thiab muaj txiaj ntsig hloov pauv ntawm cov kua dej txias, xws li liquefied natural gas (LNG) lossis lwm yam khoom siv cryogenic. Cov teeb meem tseem ceeb hauv kev tuav cov kua dej uas tsis muaj qhov kub thiab txias yog tswj xyuas cov kua dej kub, tiv thaiv thermal shock, thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv. Nov yog cov ntsiab lus tseem ceeb hauv qab ntawm kev tsim thiab kev ua haujlwm ntawm qhov ntsuas kub qis qis:
Thermal rwb thaiv tsev: Tsawg-kub loading caj npab yog nruab nrog tshwj xeeb rwb thaiv tsev cov ntaub ntawv thiab cov tswv yim kom txo tau tshav kub hloov ntawm cov dej txias thiab ib puag ncig. Qhov no pab tswj cov kua dej kub thiab tiv thaiv kom tsis txhob kub dhau.
Kev xaiv cov ntaub ntawv: Cov khoom siv ntawm cov khoom siv qis qis qis yog tsim los ntawm cov khoom siv thermal conductivity zoo heev los tiv thaiv kev hloov hluav taws xob. Cov ntaub ntawv no xyuas kom meej tias qhov chaw thau khoom ntawm caj npab tseem nyob ruaj khov thiab txo qhov kev pheej hmoo ntawm thermal stress lossis qaug zog.
Flexible Piping: Tsawg-temperature loading caj npab feem ntau siv cov hoses hloov tau yooj yim los yog cov kav dej uas tsim los tiv thaiv qhov kub tsis tshua muaj siab yam tsis muaj nkig lossis tawg. Cov khoom hloov tau yooj yim no tso cai rau kev txav mus los thiab yoog raws thaum thauj khoom thiab tshem tawm thaum tswj xyuas qhov kub thiab txias.
Sealing Mechanisms: Cryogenic kua tuaj yeem ua rau cov ntaub ntawv cog lus thiab nthuav dav vim qhov kub thiab txias. Cov txheej txheem tshwj xeeb sealing tau muab tso rau hauv qhov chaw thau khoom ntawm caj npab tsim kom haum raws li cov thermal txav no thaum ua kom muaj kev sib txuas sib txuas.
Kev Tswj Siab: Cov kua dej Cryogenic feem ntau raug xa mus rau hauv siab kom tswj tau lawv cov kua hauv lub xeev. Lub tshuab tswj lub siab tau muab tso rau hauv qhov chaw thau khoom los tswj thiab tswj cov kua dej thaum lub sijhawm hloov.
Kev Nyab Xeeb Nta: Cov caj npab qis qis yog nruab nrog cov yam ntxwv kev nyab xeeb xws li kev kaw thaum muaj xwm txheej ceev, lub siab nyem li qub, thiab cov sib txuas sib txuas kom tsis txhob muaj kev kub ntxhov ntau dhau, txo qhov kev pheej hmoo ntawm kev xau, thiab ua kom muaj kev nyab xeeb.
Differential Movement Compensation: Cryogenic loading caj npab yog tsim los kom haum rau qhov sib txawv txav los ntawm kev nthuav dav thiab kev cog lus ntawm cov khoom vim qhov kub thiab txias. Swivel pob qij txha thiab kev sib txuas yooj yim yog siv los tso cai rau cov khoom thauj khoom txav mus los yam tsis muaj kev puas tsuaj.
Kev Tswj Vapor: Thaum hloov cov kua dej cryogenic, kev tswj vapor yog qhov tseem ceeb los tiv thaiv kev tsim cov siab los ntawm evaporating gases. Vapor xa rov qab kab lossis cov tshuab tau muab tso rau hauv qhov chaw thau khoom los tswj cov vapor thiab tiv thaiv cov xwm txheej dhau los.
Kev Nyab Xeeb Kev Nyab Xeeb: Cov cuab yeej tiv thaiv tshwj xeeb thiab cov txheej txheem muaj nyob rau hauv qhov chaw kom ntseeg tau tias muaj kev nyab xeeb ntawm cov neeg ua haujlwm ua haujlwm nrog cryogenic loading caj npab. Qhov no suav nrog cov cuab yeej tiv thaiv tus kheej (PPE) thiab kev cob qhia txog kev tuav cov kua dej txias heev.
