Kuv yuav tsum xyuam xim dab tsi thaum tshuaj xyuas cov tso kua dej cryogenic?

Kev tshuaj xyuas lub tank cia kua cryogenic muab faib ua kev tshuaj xyuas sab nraud, kev tshuaj xyuas sab hauv thiab kev tshuaj xyuas ntau yam. Kev tshuaj xyuas tsis tu ncua ntawm cov tank cia cryogenic yuav tsum txiav txim siab raws li cov xwm txheej kev siv ntawm cov tank cia.

 Feem ntau, kev tshuaj xyuas sab nraud yog tsawg kawg ib xyoos ib zaug, kev tshuaj xyuas sab hauv yog tsawg kawg ib zaug txhua 3 xyoos, thiab kev tshuaj xyuas ntau yam yog tsawg kawg ib zaug txhua 6 xyoos. Yog tias lub tank cia khoom kub qis muaj lub neej ua haujlwm ntau dua 15 xyoos, kev tshuaj xyuas sab hauv thiab sab nraud yuav tsum tau ua txhua ob xyoos. Yog tias lub neej ua haujlwm yog 20 xyoo, kev tshuaj xyuas sab hauv thiab sab nraud yuav tsum tau ua tsawg kawg ib xyoos ib zaug.

1. Kev tshuaj xyuas sab hauv

 1). Seb puas muaj kev hnav corrosive ntawm sab hauv thiab lub tank cia khoom sib txuas ntawm lub qhov dej, thiab seb puas muaj cov kab nrib pleb hauv qhov vuam seam, thaj chaw hloov pauv ntawm lub taub hau lossis lwm qhov chaw uas muaj kev ntxhov siab;

 2). Thaum muaj xeb ntawm sab hauv thiab sab nraud ntawm lub tank, yuav tsum ntsuas ntau qhov tuab ntawm phab ntsa ntawm qhov chaw xav tias muaj xeb. Yog tias qhov tuab ntawm phab ntsa ntsuas tsawg dua qhov tuab ntawm phab ntsa me me uas tsim, yuav tsum rov kuaj xyuas qhov muaj zog, thiab cov lus qhia txog seb nws puas tuaj yeem siv tau thiab qhov siab ua haujlwm siab uas tso cai yuav tsum tau muab tso rau pem hauv ntej;

 3). Thaum phab ntsa sab hauv ntawm lub tank muaj qhov tsis zoo xws li decarburization, kev ntxhov siab corrosion, intergranular corrosion thiab qaug zog tawg, kev tshuaj xyuas metallographic thiab kev ntsuas qhov nyuaj ntawm qhov chaw yuav tsum tau ua, thiab daim ntawv tshaj tawm tshuaj xyuas yuav tsum xa mus.

2. Kev tshuaj xyuas sab nraud

 1). Xyuas seb cov txheej tiv thaiv xeb, cov txheej rwb thaiv tsev thiab cov ntawv cim khoom siv ntawm lub tank cia puas zoo, thiab seb cov khoom siv kev nyab xeeb thiab cov khoom siv tswj hwm puas tiav, rhiab heev thiab txhim khu kev qha;

 2). Seb puas muaj cov kab nrib pleb, deformation, qhov chaw overheating, thiab lwm yam ntawm sab nraud;

 3). Seb qhov vuam ntawm cov yeeb nkab txuas thiab cov khoom siab puas xau, seb cov ntsia hlau puas ruaj khov, seb lub hauv paus puas poob, tilting lossis lwm yam mob tsis zoo.

3, Kev tshuaj xyuas tiav

 1). Ua ib qho kev tshuaj xyuas tsis puas tsuaj rau ntawm qhov txuas tseem ceeb lossis lub plhaub, thiab qhov ntev ntawm qhov kev kuaj xyuas qhov chaw yuav tsum yog 20% ​​ntawm tag nrho qhov ntev ntawm qhov txuas;

 2). Tom qab dhau qhov kev tshuaj xyuas sab hauv thiab sab nraud, ua qhov kev sim hydraulic ntawm 1.25 npaug ntawm qhov siab tsim ntawm lub tank cia khoom thiab kev sim airtight ntawm qhov siab tsim ntawm lub tank cia khoom. Hauv cov txheej txheem tshuaj xyuas saum toj no, lub tank cia khoom thiab cov welds ntawm txhua qhov chaw tsis muaj qhov xau, thiab lub tank cia khoom tsis muaj qhov tsis zoo li qub raws li tsim nyog;

 Tom qab kev tshuaj xyuas lub tank cia khoom uas kub qis tiav lawm, yuav tsum ua daim ntawv qhia txog kev tshuaj xyuas lub tank cia khoom, qhia txog cov teeb meem thiab cov laj thawj uas siv tau lossis siv tau tab sis yuav tsum tau kho thiab siv tsis tau. Daim ntawv tshuaj xyuas yuav tsum khaws cia rau hauv cov ntaub ntawv rau kev saib xyuas thiab kev tshuaj xyuas yav tom ntej.
