Izakhono zokusebenzisa imihla ngemihla zesithando sokutshisa i-vacuum

Isithando somlilo esitshiza nge-vacuum sisetyenziswa kakhulu kwinkqubo yokutshiza izinto ze-semiconductor kunye nezixhobo zokulungisa amandla. Singenza ukutshiza nge-vacuum, ukutshiza ngegesi kunye nokutshiza okuqhelekileyo. Sisixhobo senkqubo esitsha kuluhlu lwezixhobo ze-semiconductor ezikhethekileyo. Sinombono woyilo olutsha, ukusebenza okulula kunye nesakhiwo esincinci. Ukuhamba kweenkqubo ezininzi kunokugqitywa kwisixhobo esinye. Singasetyenziswa kwakhona kunyango lobushushu be-vacuum, i-vacuum brazing kunye nezinye iinkqubo kwezinye iindawo.

Izakhono eziyimfuneko zokusebenzisa isithando sokutshisa i-vacuum

Isithando somlilo esinomoya ophezulu sisetyenziselwa ukwenza i-tungsten crucible kwi-coil ivelise ubushushu obuphezulu phantsi kokhuseleko lokuzaliswa kwe-hydrogen emva kokupompa i-vacuum kunye nomgaqo wokufudumeza okuphakathi, okudluliselwa kumsebenzi ngemitha yobushushu. Sifanelekile ekwenzeni i-powder kunye nokusila i-refractory alloys ezifana ne-tungsten, i-molybdenum kunye ne-alloys zazo kuphando lwesayensi kunye neeyunithi zoshishino zomkhosi. Indawo apho isithando sombane sifakwe khona kufuneka ihlangabezane neemfuno zococeko lwe-vacuum, umoya ojikelezileyo kufuneka ucoceke kwaye wome, kwaye kufuneka kubekho iimeko ezifanelekileyo zomoya. Indawo yokusebenza ayilula ukuphakamisa uthuli, njl.

Izakhono zokusebenzisa imihla ngemihla zesithando sokutshisa i-vacuum:

1. Jonga ukuba zonke izinto kunye nezixhobo kwikhabhinethi yokulawula ziphelele kwaye ziphelele na.

2. Ikhabhinethi yokulawula kufuneka ifakwe kwisiseko esifanelekileyo kwaye iqine.

3. Ngokwesazobe socingo kunye nokubhekisa kwisazobe somatshini wombane, qhagamshela isekethe eyintloko yangaphandle kunye nesekethe yokulawula, kwaye uxhase ngokuqinileyo ukuqinisekisa ukuba i-wiring ilungile.

4. Qinisekisa ukuba inxalenye eshukumayo yesixhobo sombane kufuneka ihambe ngokukhululekileyo ngaphandle kokuxinana.

5. Ukumelana nobushushu akufuneki kube ngaphantsi kwe-2 megohm.

6. Zonke iivalvu zesithando sombane esingenamoya kufuneka zibe kwindawo evaliweyo.

7. Beka iswitshi yombane yokulawula kwindawo yokucima.

8. Jika iqhosha elilawula uxinzelelo ngesandla uliguqulele kwicala elichasene newotshi.

9. Beka iqhosha le-alamu kwindawo evulekileyo.

10. Gqibezela uqhagamshelo lwamanzi okupholisa olujikelezayo lwesixhobo ngokwesicwangciso. Kucetyiswa ukuba umsebenzisi aqhagamshele amanye amanzi amisiweyo (amanzi empompini afumanekayo) kumbhobho ophambili wokungena kunye nowokuphuma wesixhobo ukuthintela iringi yokutywina ukuba ingatshi ngenxa yokusilela kwamanzi ajikelezayo okanye ukusilela kombane.
