Ipayipi elifakwe i-vacuum lisetshenziselwa ukudlulisa indawo yokushisa ephansi, futhi linomphumela okhethekile wepayipi elifakwe i-vacuum elibandayo. Ukufakwa kwepayipi elifakwe i-vacuum kuhlobene. Uma kuqhathaniswa nokwelashwa okuvamile okufakwe i-vacuum, ukufakwa kwe-vacuum kusebenza kangcono.

Unganquma kanjani ukuthi ipayipi elifakwe i-vacuum cleaner lisesimweni sokusebenza esisebenzayo ngesikhathi sokusetshenziswa kwalo isikhathi eside? Ngokuyinhloko ngokubheka ukuthi udonga lwangaphandle lwepayipi le-VI lubonakala yini njengesimo samanzi nesithwathwa. (Uma ipayipi elifakwe i-vacuum cleaner lifakwe i-vacuum gauge, izinga le-vacuum lingafundwa.) Ngokuvamile, sithi isimo samanzi nesithwathwa esakheka odongeni lwangaphandle lwepayipi le-VI ukuthi izinga le-vacuum alanele, futhi alikwazi ukuqhubeka nokudlala indima efakwe i-vacuum ngempumelelo.

Izimbangela Zesimanga Sokufiphaza Kwamanzi Nokuqanda

Ngokuvamile kunezimbangela ezimbili zokuqandisa,

● Umlomo womshini wokuhlanza noma wokuwelda uyavuza, okuholela ekunciphiseni komoya wokuhlanza.

● Ukukhishwa kwegesi ngokwemvelo ezintweni ezisetshenziswayo kubangela ukwehla kwe-vacuum.

Ukuvuza kwe-vacuum nozzle noma ukuvuza kwe-weld, okungokwemikhiqizo engafanele. Abakhiqizi abanazo imishini yokuhlola esebenzayo kanye nohlelo lokuhlola ekuhlolweni. Imikhiqizo yokuvikela i-vacuum eyenziwe abakhiqizi abahle kakhulu ngokuvamile ayinazo izinkinga kulokhu ngemuva kokulethwa.

Izinto zikhipha igesi, okuyinto engenakugwenywa. Ekusetshenzisweni kwesikhathi eside kwepayipi le-VI, insimbi engagqwali nezinto ezifakwe umswakama zizoqhubeka nokukhipha igesi ku-vacuum interlayer, zinciphise kancane kancane izinga le-vacuum le-vacuum interlayer. Ngakho ipayipi le-VI linempilo ethile yesevisi. Lapho izinga le-vacuum lehla liye esimweni esingenakuba yi-adiabatic, ipayipi le-VI lingasuswa umswakama okwesibili ngeyunithi yokupompa ukuze kuthuthukiswe izinga le-vacuum futhi kubuyiselwe umphumela walo ofakwe umswakama.

Ukuqandisa akwanele ukuhlanza i-vacuum, futhi kunjalo nangamanzi?

Uma kwenzeka ukwakheka kwamanzi epayipini le-vacuum adiabatic, izinga le-vacuum alilingene ngempela.

Okokuqala, umphumela wokushisa wepayipi le-VI ulinganiselwe. Uma izinga lokushisa lodonga lwangaphandle lepayipi le-VI lingaphansi kwezinga lokushisa elingaphakathi kwe-3 Kelvin (elilingana no-3℃), ikhwalithi yepayipi le-VI ibhekwa njengeyamukelekayo. Ngakho-ke, uma umswakama wendawo uphezulu ngaleso sikhathi, lapho izinga lokushisa lepayipi le-VI lingaphansi kuka-3 Kelvin endaweni ezungezile, kuzokwenzeka futhi ukuminyana kwamanzi. Idatha ethile iboniswe esithombeni esingezansi.

Isibonelo, uma umswakama ozungezile ungama-90% kanti izinga lokushisa elizungezile lingu-27℃, izinga lokushisa elibalulekile lokwakheka kwamanzi ngalesi sikhathi lingu-25.67℃. Okusho ukuthi, uma umehluko wokushisa phakathi kwepayipi le-VI nendawo ezungezile ungu-1.33℃, kuzovela isimo sokuminyana kwamanzi. Kodwa-ke, umehluko wokushisa ongu-1.33℃ ungaphakathi kwebanga lobunzima bepayipi le-VI, ngakho-ke akunakwenzeka ukuthuthukisa isimo sokuminyana kwamanzi ngokuthuthukisa ikhwalithi yepayipi le-VI.

Ngalesi sikhathi, siphakamisa ukuthi kufakwe imishini yokususa umswakama, kuvulwe ifasitela lokungenisa umoya, futhi kuncishiswe umswakama ongokwemvelo, ukuze kuthuthukiswe ngempumelelo isimo sokuminyana kwamanzi.
