Yintoni injongo yokufumanisa ukuvuza ngaphakathi emoyeni eziko emoyeni

Iziko lokufunxa umoya we-vacuum ziqhele ukusetyenziswa kwiindawo ezahlukeneyo zomoya ezifana ne-vacuum, i-hydrogen, i-oksijini, i-nitrogen, kunye ne-inert gases (efana ne-argon). Masiqonde izinto zokubona ukuvuza kwesithando somlilo esifunxileyo.

I-airtightness ye-vacuum system kwi-vacuum atmosphere esithandweni kukuthintela ukusebenza kwegesi evuzayo, kubandakanywa ukuvuza komngxuma wokuvuza (okanye i-gap) kunye nokuvuza kwezinto, kwaye umgangatho wayo udla ngokubonakaliswa yizinga lokuvuza. Isantya sokuvuza sisixa serhasi equkuqela kwindawo evuzayo (kubandakanywa nomsantsa) ngexesha leyunithi. Kumgangatho wamazwe ngamazwe, izinga lokuvuza lichazwa ngolu hlobo: uxinzelelo lokungena kwi-hole yokuvuza yi-1 * 0.1 * 105Pa, uxinzelelo lwe-outlet lungaphantsi kwe-1.33 * 103Pa, kwaye ubushushu ngu-23 ℃ ± 7℃. Phantsi kweemeko eziqhelekileyo, iqondo lombethe lingaphantsi kwe -25℃. , Ubungakanani berhasi ehamba ngokuvuza ngexesha leyunithi.

Injongo yokukhangela ukuvuza kwevacuum ayikona nje ukugqiba ukuba inkqubo iyavuza, kunye nokufumanisa ngokobungakanani ubungakanani bezinga lokuvuza, kodwa okona kubaluleke kakhulu, ukufumana indawo yokuvuza okanye unobangela wokuvuza, ukuze amanyathelo akwazi kuthathwe kulungiswe. Umgaqo osisiseko kukusebenzisa umahluko woxinzelelo phakathi kwangaphakathi nangaphandle kwenkqubo ye-vacuum yesithando somlilo somlilo ukwenza irhasi ihambe kwaye isebenzise iindlela ezithile zobugcisa ukufumanisa indawo yokuvuza.

Isixokelelwano se-vacuum se-vacuum atmosphere esithandweni sizaliswe ngegesi engaphezulu koxinzelelo lwe-atmospheric, kwaye indlela yokwenza irhasi ihambe ukusuka ngaphakathi ukuya ngaphandle ukuze kubonwe ukuvuza kubizwa ngokuba yindlela yokufumanisa ukuvuza koxinzelelo olulungileyo. Isixhobo sokubona ukuvuza sibona irhasi evuzayo ngaphandle ukufumanisa ukuvuza. Indawo yomngxuma kunye nesantya sokuvuza. Inkqubo ye-vacuum ikhutshwe, kwaye igesi evuzayo ifafazwe ukusuka ngaphandle ukuya kwisistim kunye nombhobho ukwenza igesi iphume ngaphandle ukuya ngaphakathi. Qwalasela utshintsho ekufundeni kwesixhobo sokuvuza ukumisela indawo ekuvuza kuyo kunye nesantya sokuvuza. Olu hlobo lokubona ukuvuza kubizwa ngokuba yindlela yokufumanisa ukuvuza okungalunganga.
