Izilumkiso zokusetyenziswa kwesithando somlilo sevacuum
Imiqathango yokusetyenziswa kwe emoyeni eziko emoyeni
1. Ngaphambi kokufudumeza isithando somlilo se-vacuum, umbhobho wokupholisa kufuneka uqhagamshelwe kulwelo lokupholisa ukuze ujikeleze ukupholisa. Xa iqondo lobushushu lingekho phezulu, lisenokupholiswa ngokujikeleza kwamanzi. Xa unyusa amaqondo obushushu, nceda ubeke ingqalelo kukhuseleko lwe-atmosphere okanye i-vacuum state. Kunqatshelwe ngokungqongqo ukutshisa kwindawo yokukhusela engekho-atmosphere kunye ne-non-vacuum state okanye ukubeka izinto kunye nokwandiswa kwegesi.
2. Xa i-furnace ihlanjululwa, akufanele idlule izikali ezimbini zesalathisi (ukuba idlula izikali ezimbini ze-vacuum gauge xa i-vacuum ikhutshwe, iya kulimaza i-vacuum atmosphere yomlilo). Xa isalathisi se-vacuum gauge siwela kufutshane nezahlulo ezimbini, yeka ukumpompa kunye nokutshaja. Gcwalisa i-gas ye-inert, yenza i-pointer ibuyele kwi-0 okanye ikhulu kancinane kune-0, emva koko impompe kwaye ifake umoya, iphinde i-3 ukuya kumaxesha angama-5 ukuqinisekisa ukuba igesi ekhuselayo kwi-cavity yesithando somlilo inogxininiso oluthile.
3. Xa i-workpiece ayifuni ukukhuselwa kwe-atmosphere, isithando somlilo se-vacuum kufuneka sidibaniswe nombhobho wokungena, uzaliswe ngegesi engcolileyo, kwaye ukhulule kancinci i-valve yokuphuma kwegesi. Xa igesi ehlawuliswayo inkulu kunomthamo wesithando somlilo, i-valve yokuphuma kwegesi kufuneka ivalwe. Igeyiji yoxinzelelo loqwalaselo kufuneka ibe nkulu kuno-“0” Ngaphantsi kweebhloko ezimbini.
4. Iqokobhe le-vacuum atmosphere furnace kufuneka lisekelwe ngokufanelekileyo ukuqinisekisa ukusetyenziswa ngokukhuselekileyo; umzimba wesithando somlilo kufuneka ubekwe kwigumbi elinomoya, kwaye akukho zixhobo ezinokutsha kunye neziqhushumbisi kufuneka zibekwe ngeenxa zonke; Umzimba wesithando somlilo uchitha ubushushu.
