Txoj kev kho rau lub raj ntim cov xau ntawm titanium tshav kub exchanger

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 nyuaj rau kev kho cov raj xau. Kho vuam tsis yog ib txoj kev zoo, vim hais tias yuav tsum muaj impurities nyob rau hauv lub qhov sib txawv ntawm lub raj thiab lub raj ntawv thaum lub sij hawm siv, uas yuav ua rau muaj zog npuas, slag, interlayers thiab lub zos kev nyuaj siab concentration tshwm sim los ntawm welding thaum lub sij hawm vuam txheej txheem. , Cov kab nrib pleb tuaj yeem tshwm nyob ze ntawm qhov kho vuam nozzle, ua rau cov xau tshiab.
Yog li ntawd, rau lub zog ntawm welded titanium tshav kub exchanger raj bundles, txoj kev kom tsis txhob tsis ua hauj lwm ntawm solder pob qij txha yog: ib tug yog xaiv cov khoom tsim nyog, uas yog, xaiv lub raj ntawv thiab tshav kub exchanger raj tsim nyog raws li qhov nruab nrab, tshwj xeeb tshaj yog kom tsis txhob muaj hluav taws xob poob ntawm cov ntawv raj thiab lub raj. tshuaj corrosion. Qhov thib ob, qhov kev nkag mus ntawm vuam yuav tsum tau ua kom ntseeg tau ntawm lub hauv paus ntawm lub vuam, thiab yuav tsum muaj qhov siab txaus kom muaj zog (siab dua 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 los xyuas kom meej tias cov pob qij txha ntawm titanium kub exchangers tsis poob.
Rau cov ntshiab lub zog expansion raj bundles, lub expansion chaw nres nkoj xau thiab yuav tsum tau muab ntxiv tom qab siab nyem, thiab tus naj npawb ntawm ntxiv expansions yuav tsum tsis txhob ntau tshaj peb zaug.
