Inkqubo yokuvavanya ukufana kwe iqondo lobushushu lesithando somlilo

1. Ngokweemfuno zenkqubo ye-vacuum brazing, khetha iqondo lokushisa lokulinganisa kwi-650 ℃, 850 ℃ kunye ne-1000 ℃, kwaye usethe ijika lokufudumala kwisixhobo sokulawula ukushisa kwe-FP23.

2. Emva kokuba isibini esilawulayo sifikelele kwiqondo lokushisa elibekiweyo kwimizuzu ye-120, qalisa ukulinganisa ixabiso le-thermocouple nganye. Funda kube kanye ngemizuzu emi-5, amaxesha ama-3 ngokulandelelana. Ukuba ubushushu bendawo nganye bungaphakathi kwe-± 5℃ yobushushu obufunekayo, umlinganiselo wale ndawo yobushushu ugqityiwe, kungenjalo uqhubeke u-isothermal de iqondo lobushushu lifane okanye ixesha lifikelele kwi-3h (ukugcinwa kobushushu kusekwe yinkqubo) ) kwaye urekhode iqondo lobushushu kwindawo nganye.

3. Lungisa i-FP23 meter, yandisa iqondo lokushisa ukusuka kwi-650 ° C ukuya kwi-850 ° C, gcina ubushushu bemizuzu ye-120, kwaye uphinde ulandele inkqubo yokulinganisa iqondo lokushisa kwe-650 ° C. Ngokufanayo, iqondo lokushisa linyuka ukusuka kwi-850 ° C ukuya kwi-1100 ° C, ukushisa kugcinwe imizuzu eyi-120, kwaye inkqubo yokulinganisa iqondo lokushisa iphinda iphindwe kwi-650 ° C.

4. Gcwalisa le datha ingentla kwitheyibhile yeerekhodi ngokulandelelanayo. Emva kokuba umlinganiselo ugqityiwe, landela inyathelo eliqhelekileyo lokupholisa isithando somlilo ukuze uphole.

5. Emva kokupholisa phantsi, vula umnyango wesithando somlilo, ukhuphe i-bracket yokulinganisa, udibanise ucingo lwentsimbi olulungisa i-thermocouple, susa i-flange, ufake i-plate ye-cover yokuqala, kwaye wenze uvavanyo lokunyuka koxinzelelo ngokusetyenziswa ngokuqhelekileyo.

6. Qalisa ngesandla i-vacuum mechanical pump kunye ne-vacuum Ipompo yeengcambu zokupompa i-vacuum ngokwemigaqo yokusebenza, de kube i-vacuum yokusebenza ifike kwi-2Pa, yimise i-30min, jonga ukufundwa kwe-vacuum gauge, kwaye ubone ukuba izinga lokunyuka koxinzelelo lingaphakathi. eqhelekileyo 0.5Pa/h. Ukuba ifanelekile, qhubeleka, kwaye isixhobo sinokusetyenziswa ngokuqhelekileyo, kungenjalo qhubeka ufaka izibuko lokulinganisa ubushushu bokuqala.
