Inqubo yokuhlola ukufana kwe izinga lokushisa lomlilo we-vacuum

1. Ngokuya ngezidingo zenqubo ye-vacuum brazing, khetha amaphuzu okushisa okulinganisa ku-650℃, 850℃ no-1000℃, bese usetha ijika lokushisa ethuluzini lokulawula izinga lokushisa le-FP23.

2. Ngemva kokuba umbhangqwana olawulayo ufinyelele izinga lokushisa elimisiwe imizuzu engu-120, qala ukukala inani le-thermocouple ngayinye. Funda kanye njalo emizuzwini emi-5, izikhathi ezi-3 zilandelana. Uma izinga lokushisa lephuzu ngalinye lingaphakathi kuka-±5℃ wezinga lokushisa elidingekayo, ukukalwa kwaleli phuzu lokushisa kuyaqedwa, ngaphandle kwalokho qhubeka ne-isothermal kuze kube yilapho izinga lokushisa lifana noma isikhathi sifinyelela ku-3h (ukugcinwa kokushisa okusethwe inqubo) Isikhathi ) bese urekhoda izinga lokushisa endaweni ngayinye.

3. Lungisa imitha ye-FP23, ukhuphule izinga lokushisa lisuka ku-650°C liye ku-850°C, gcina izinga lokushisa imizuzu eyi-120, bese uphinda inqubo yokulinganisa izinga lokushisa elingu-650°C. Ngokufanayo, izinga lokushisa liyenyuka ukusuka ku-850 ° C kuya ku-1100 ° C, izinga lokushisa ligcinwa imizuzu engu-120, futhi inqubo yokulinganisa iphuzu lokushisa iphindwe ku-650 ° C.

4. Gcwalisa idatha engenhla etafuleni lerekhodi ngokulandelanayo. Ngemva kokuqedwa kokulinganisa, landela isinyathelo esivamile sokupholisa isithando somlilo esingenalutho ukuze uphole.

5. Ngemva kokupholisa phansi, vula umnyango wesithando somlilo, ukhiphe ubakaki wokulinganisa, uqaqe intambo yensimbi elungisa i-thermocouple, khipha i-flange, faka ipuleti lokuqala lekhava, futhi wenze ukuhlolwa kwezinga lokucindezela ngokuvumelana nokusetshenziswa okuvamile.

6. Qala ngokuzenzela iphampu kamshini wokuvala kanye ne-vacuum Iphampu yezimpande ukuze ipompe ivacuum ngokwemithetho yokusebenza, kuze kube yilapho isivacu esisebenzayo sifika ku-2Pa, yima imizuzu engama-30, bheka ukufundwa kwegeji ye-vacuum, futhi ubone ukuthi izinga lokwenyuka kwengcindezi lingaphakathi yini. evamile 0.5Pa/h. Uma ifaneleka, qhubeka, futhi okokusebenza kungasetshenziswa ngokujwayelekile, ngaphandle kwalokho qhubeka nokufaka kabusha ikhava yembobo yokulinganisa izinga lokushisa yasekuqaleni.
