Nrog rau kev nce qib ntawm vuam tshuab, feem ntau ntawm txoj kev sib txuas ntawm titanium tshav kub exchanger raj bundles, cov hlab thiab cov ntawv raj yog welded los yog nthuav. Weld to ntawm lub raj thiab cov ntawv raj yog ib qho teeb meem nyuaj hauv kev kho lub raj xau. Kho vuam tsis yog ib txoj kev zoo, vim hais tias muaj impurities nyob rau hauv lub qhov sib txawv ntawm lub raj thiab lub raj ntawv thaum siv, uas ua rau muaj zog npuas, slag, interlayer thiab lub zos kev nyuaj siab concentration tshwm sim los ntawm welding tsim thaum lub sij hawm vuam txheej txheem. , cov kab nrib pleb tuaj yeem tshwm nyob ze ntawm qhov kho qhov vuam nozzle, ua rau cov xau tshiab.
Yog li ntawd, nyob rau hauv cov nqe lus ntawm lub zog ntawm welded titanium tshav kub exchanger raj bundles, txoj kev kom tsis txhob muaj kev tsis ua hauj lwm ntawm lub solder pob qij txha: ib tug yog tsim nyog xaiv cov khoom, uas yog, tsim nyog xaiv lub raj ntawv thiab lub tshav kub exchanger raj raws li ib tug tsim nyog xaiv. qhov nruab nrab, tshwj xeeb tshaj yog kom tsis txhob muaj hluav taws xob sib txuas ntawm cov ntawv raj thiab lub raj. tshuaj corrosion. Qhov thib ob, lub hauv paus ntawm lub vuam yuav tsum xyuas kom meej qhov vuam nkag thiab muaj qhov siab txaus kom muaj zog (siab tshaj lossis sib npaug li 2.5 hli). Tsis tas li ntawd, kev xyaum ntau lawm qhia tau hais tias lub zog ntawm solder paste expansion yog tus yuam sij kom ntseeg tau tias cov pob qij txha ntawm cov titanium kub exchangers tsis poob.
Rau cov ntshiab-strength expansion raj bundles, yog hais tias lub expansion chaw nres nkoj xau, nws yuav tsum tau supplemented tom qab siab nyem, thiab tus naj npawb ntawm supplementary expansions yuav tsum tsis txhob ntau tshaj peb zaug.
