Umbhobho ogqunywe nge-vacuum usetyenziselwa ukuhambisa ubushushu obuphantsi, kwaye unefuthe elikhethekileyo lombhobho ogqunywe nge-vacuum. Ubushushu bombhobho ogqunywe nge-vacuum buhambelana. Xa kuthelekiswa nonyango lwendabuko olugqunywe nge-vacuum, ubushushu bombhobho busebenza ngakumbi.

Ungafumanisa njani ukuba umbhobho ogqunywe nge-vacuum uyasebenza kakuhle ngexesha lokusetyenziswa kwawo ixesha elide? Ngokuyintloko ngokujonga ukuba udonga lwangaphandle lombhobho we-VI lubonakala ngathi luyinto yamanzi neqabaka. (Ukuba umbhobho wogqunywe nge-vacuum une-vacuum gauge, i-vacuum degree ingafundwa.) Ngokwesiqhelo, sithi into yokuba amanzi neqabaka zizenzekela eludongeni lwangaphandle lombhobho we-VI kukuba i-vacuum degree ayanelanga, kwaye ayinakuqhubeka nokudlala indima egqunywe nge-vacuum.

Izizathu zeNgxaki yokuQonda kwamanzi kunye nokuQhotsa

Zimbini izizathu ezibangela i-frosting,

● I-vacuum nozzle okanye i-welds ziyavuza, nto leyo ebangela ukwehla kwe-vacuum.

● Ukukhululwa kwegesi ngokwendalo kwizinto ezisetyenzisiweyo kubangela ukuncipha kwe-vacuum.

I-vacuum nozzle okanye ukuvuza kwe-weld, okuyimveliso ezingafanelekanga. Abavelisi abanazo izixhobo zokuhlola ezisebenzayo kunye nenkqubo yokuhlola xa kuhlolwa. Iimveliso ze-vacuum insulation ezenziwe ngabavelisi ababalaseleyo zihlala zingenazo iingxaki kule nkalo emva kokuhanjiswa.

Ezi zinto zikhupha igesi, into engenakuphepheka. Ekusetyenzisweni kwexesha elide kombhobho we-VI, intsimbi engatyiwayo kunye nezinto ezigqunyiweyo ziya kuqhubeka nokukhupha igesi kumbhobho ogqunyiweyo, zinciphise kancinci iqondo lokukhupha umoya lombhobho ogqunyiweyo. Ngoko umbhobho we-VI unobomi obuthile benkonzo. Xa iqondo lokukhupha umoya lihla liye kwimeko engenakuba yi-adiabatic, umbhobho we-VI unokukhucululwa okwesibini ngeyunithi yokumpompa ukuphucula iqondo lokukhupha umoya kunye nokubuyisela isiphumo sawo sokukhusela umoya.

Ukuqandisa akwanelanga ukucoca nge-vacuum, kwaye kunjalo nangamanzi?

Xa kwenzeka into yokwakheka kwamanzi kwityhubhu ye-vacuum adiabatic, inqanaba le-vacuum alanelanga.

Okokuqala, isiphumo sobushushu bombhobho we-VI sihambelana. Xa ubushushu bodonga lwangaphandle lombhobho we-VI bungaphantsi kobushushu obuphakathi kwe-3 Kelvin (elingana ne-3℃), umgangatho wombhobho we-VI uthathwa njengowamkelekileyo. Ke ngoko, ukuba umswakama wokusingqongileyo uphezulu ngelo xesha, xa ubushushu bombhobho we-VI bungaphantsi kwe-3 Kelvin ukusuka kokusingqongileyo, isiganeko sokufuma kwamanzi siya kwenzeka. Idatha ethile iboniswe kumfanekiso ongezantsi.

Umzekelo, xa umswakama ojikeleze umhlaba ungama-90% kwaye ubushushu obujikeleze umhlaba bungama-27℃, ubushushu obubalulekileyo bokwenziwa kwamanzi ngeli xesha bungama-25.67℃. Oko kukuthi, xa umahluko wobushushu phakathi kombhobho we-VI kunye nokusingqongileyo uyi-1.33℃, kuya kuvela imeko yokufuma kwamanzi. Nangona kunjalo, umahluko wobushushu we-1.33℃ ukwinqanaba lobunzima bombhobho we-VI, ngoko akunakwenzeka ukuphucula imeko yokufuma kwamanzi ngokuphucula umgangatho wombhobho we-VI.

Ngeli xesha, sicebisa ukuba kongezwe izixhobo zokususa ubumanzi, kuvulwe ifestile ukuze kungene umoya, kwaye kuncitshiswe ukufuma kokusingqongileyo, ukuze kuphuculwe ngempumelelo imeko yokufuma kwamanzi.
