Vuam txheej txheem ntawm evaporator condenser tooj liab raj luj tshib

Preheat:
Siv rab phom vuam lossis tshuab vuam los ua kom sov qhov vuam, ua kom qhov kub ntawm qhov vuam, thiab txo qhov kev ntxhov siab ntawm vuam.
Welding kev ua haujlwm:
Xaiv qhov tsim nyog vuam tsis zoo (xws li kub, sijhawm, siab, thiab lwm yam) raws li txoj kev vuam (xws li brazing, fusion vuam, thiab lwm yam).
Lub vuam hlau yog dipped nyob rau hauv ib tug tsim nyog tus nqi ntawm flux thiab xa mus rau lub vuam qhov chaw, thiab lub tshav kub generated los ntawm vuam phom los yog vuam tshuab yog siv los yaj thiab fuse lub vuam hlau thiab tooj liab raj ua ke.
Ua tib zoo saib xyuas qhov ntsuas kub thiab lub sijhawm kom tsis txhob muaj cua sov ntau uas ua rau lub raj tooj liab deformation lossis vuam tsis zoo.
Weld kev kho mob:
Tom qab welding, so lub weld nto nrog ib daim ntaub ntub dej los yog ib lub tshuab ntxhua khaub ncaws tshwj xeeb kom tshem tawm cov dej seem thiab oxide.
Tshawb xyuas qhov zoo ntawm qhov vuam, xyuas kom tsis muaj kab nrib pleb, qhov hws thiab lwm yam tsis xws luag hauv qhov vuam, thiab ua kom tsim nyog kho.

Kev tswj kom zoo

Kev tshuaj xyuas qhov tshwm sim:
Xyuas seb qhov zoo li ntawm qhov vuam yog du thiab du, tsis muaj kab nrib pleb, pores thiab lwm yam tsis xws luag.
Xyuas seb qhov vuam yog ruaj khov thiab txhim khu kev qha, tsis muaj qhov tshwm sim los yog xoob.
Tightness xeem:
Siv nitrogen los yog refrigerant los ntsuas lub vuam qhov chaw los xyuas seb cov vuam qhov txuas puas raug kaw.
Yog tias muaj cov dej xau, nws yuav tsum tau kho thiab rov sim dua hauv lub sijhawm.
Kev xeem ua haujlwm:
Tom qab qhov kev teeb tsa tiav lawm, tag nrho cov kev ntsuas kev ua tau zoo tau ua tiav los xyuas kom meej tias cov txheej txheem vuam ntawm cov evaporator condenser tooj liab raj lub luj tshib ua tau raws li cov qauv tsim thiab cov txheej txheem kev ua haujlwm.
