Q: dab tsi's qhov txawv ntawm shrink tube expansion thiab shrinkless raj expansion?
A:
Qhov txawv ntawm covntsws tube expansion thiabshrinkless tube expansion txheej txheem nyob rau hauv lub tshav kub exchangers yog ib qho tseem ceeb nyob rau hauv cov nqe lus ntawm lub hauv paus ntsiab lus thiab kev siv.
Shrink cev expansion
Covntsws tube expansion txheej txheem yog ib qho kev siv tshuab tsim khoom. Thaum lub sij hawm lub raj expansion, txoj kab uas hla ntawm lub raj tooj liab nce vim qhov loj ntawm lub expansion pob piv rau lub puab txoj kab uas hla ntawm lub raj, uas ua rau kom nruj kev sib cuag nrog cov fins thiab txhim kho tshav kub hloov efficiency ntawm lub tshav kub exchanger. Txawm li cas los xij, hom kev nthuav dav ntawm lub raj no ua rau muaj qhov nce ntawm qhov chaw hla ntawm lub raj tooj liab, uas ua rau txo qhov ntev ntawm lub raj, hu ua tooj liab raj shrinkage tus nqi. Piv txwv li, nyob rau hauv kev lag luam cua txias, lub shrinkage tus nqi ntawm internally threaded tooj liab raj yog feem ntau 3% -4%.
Shrinkless cev expansion
The shrinkless tube expansion txheej txheem yog ib txoj kev yuam tube expansion. Nws them nyiaj rau qhov nce hauv txoj kab uas hla ntawm lub raj tooj liab los ntawm kev nce phab ntsa tuab, kom ntseeg tau tias tsis muaj qhov shrinkage nyob rau hauv qhov ntev ntawm lub raj tooj liab tom qab lub raj nthuav dav. Cov txheej txheem no yuav tsum tau siv ib qho tshwj xeeb fixture ntawm lub raj expanding tshuab kom clamp lub raj xaus thiabPlaub hau-tube hauv qab ntawm lub tshav kub exchanger Cheebtsam ua ntej lub raj expansion. Tom qabshrinkless Tube expansion, kev hloov pauv tshwm sim nyob rau hauv txoj kab uas hla thiab xov tsis tau ntawm lub raj tooj liab, yuav tsum tau validation ntawm lub tshav kub exchanger kev ua tau zoo, system siab, thiab mus sij hawm ntev kev khiav hauj lwm ntawm lub tshav kub exchanger. Tsis tas li ntawd, qee cov qauv tsim ntawmshrinkless tube expansion muaj xws li sab hauv tav uas siv lub zog tensile rau lub raj lub cev thaum lub sij hawm nthuav dav txheej txheem, tiv thaiv lub raj shrinkage thiab kom ntseeg tau tias lub raj zoo sib xws rau kev txhim kho cua sov.
Hauv kev xaus, qhov sib txawv tseem ceeb ntawmntsws thiabshrinkless tube expansion txheej txheem nyob rau hauv seb lub raj tooj liab shrinks tom qab expansion thiab yuav ua li cas tus tsim ntawm tus txheej txheem yuav optimize qhov kev ua tau zoo ntawm lub tshav kub exchanger. Qhov kev xaiv tshwj xeeb ntawm cov txheej txheem yog nyob ntawm qhov kev thov tshwj xeeb thiab cov txheej txheem txheej txheem.
