Txheeb xyuas cov chaw tsim khoom cov lus qhia, tab sis feem ntau yog acetylene yuav tsum ua teeb mus kb10 psi ua thiab cov oxygen yuav tsum ua teeb rau kb40 psi ua.

Yog li ntawd, lub siab npaum li cas yuav tsum tau teem rau oxygen thiab acetylene rau brazing?

Tooj liab brazing tus tswj qhov chaw . Thaum nyob hauv tsev kawm ntawv rau HVAC tus kws qhia ntawv tau hais rau ib txwm teeb tus acetylene ua 7psig oxygen mus rau 15 psig rau silphos brazing tooj liab HVAC kab poob lawm.

Tom qab ntawd, lo lus nug yog, qhov siab yuav tsum tau teeb lub teeb txiav li cas? RULE OF THUMB (MULTI-HOLE Txiav TIPS, OXY / ACETYLENE ) Pom zoo oxy/ txiav acetylene taub kev nyuaj siab sib txawv nrog qhov loj me. Yog hais tias koj tsis muaj chaw tsim tshuaj paus teeb-cov ntaub ntawv, thiab yog txiav tsawg dua 1 ½ tuab tuab hlau, teeb tus acetylene tus tswj hwm rau 10 psig, thiab cov pa ntsuas pa rau 40 psig.

Tom qab ntawd, dab tsi yog qhov ua haujlwm siab rau acetylene?

Cov ua hauj lwm siab ntawm acetylene cov khoom siv yog qhov tseem ceeb: Acetylene siab yuav tsum tsis pub tshaj 0.62 bar (9psi) tshwj tsis yog cov cuab yeej tau tsim tshwj xeeb rau nws.

Qhov sib piv ntawm cov pa rau acetylene yog dab tsi?
