Ipayipi le-vacuum insulated lisetshenziselwa ukudlulisa ukushisa okuphansi okuphakathi, futhi linomphumela okhethekile wepayipi lokufaka elibandayo.I-insulation ye-vacuum insulated pipe ihlobene.Uma kuqhathaniswa nokwelashwa kwe-insulation yendabuko, ukufakwa kwe-vacuum kusebenza kakhulu.

Unganquma kanjani ukuthi ipayipi le-vacuum insulated lisesimweni esisebenzayo ngesikhathi sokusetshenziswa kwalo isikhathi eside?Ikakhulukazi ngokubheka ukuthi udonga lwangaphandle lwepayipi le-VI lubonakala yini into yamanzi nesithwathwa.(Uma i-vacuum insulation tube ifakwe i-vacuum gauge, i-vacuum degree ingafundwa.) Ngokuvamile, sithi into eyenziwa ngamanzi nesithwathwa odongeni olungaphandle lwepayipi le-VI ukuthi i-vacuum degree ayanele, futhi ayikwazi ukuqhubeka nokudlala indima eyisivikelo.

Izimbangela Zento Eyenzeka Ngamanzi Ukujiya kanye Neqhwa

Ngokuvamile kuba nezimbangela ezimbili zesithwathwa,

● Vacuum nozzle noma amashisela ayavuza, okuholela ekwehleni kwevacuum.

● Ukukhishwa kwegesi okungokwemvelo ezintweni kubangela ukuncipha kwe-vacuum.

Vacuum nozzle noma ukuvuza kokushisela, okwemikhiqizo engafanelekile.Abakhiqizi abanazo izinto zokuhlola ezisebenzayo kanye nesistimu yokuhlola lapho kuhlolwa.Imikhiqizo yokufakwa kwe-vacuum eyenziwe abakhiqizi abahle kakhulu ngokuvamile ayinazo izinkinga kulokhu ngemuva kokulethwa.

Izinto ezisetshenziswayo zikhipha igesi, okungagwemeki.Ekusetshenzisweni kwesikhathi eside kwepayipi le-VI, insimbi engagqwali kanye nezinto ezigqunyiwe zizoqhubeka nokukhulula igesi ku-vacuum interlayer, kancane kancane kunciphise izinga le-vacuum interlayer.Ngakho ipayipi le-VI linokuphila kwesevisi ethile.Lapho i-vacuum degree yehla esimweni esingenakukwazi ukuba yi-adiabatic, ipayipi le-VI lingakhishwa okwesibili ngeyunithi yokupompa ukuze kuthuthukiswe izinga le-vacuum nokubuyisela umphumela walo ofakwe ngaphakathi.

I-frosting ayiyona i-vacuum eyanele, kanjalo namanzi?

Uma kwenzeka ukwakheka kwamanzi kwenzeka ku-vacuum adiabatic tube, i-vacuum degree akwanele.

Okokuqala, umphumela we-insulated wepayipi le-VI uhlobene.Lapho izinga lokushisa elingaphandle lodonga lwepayipi le-VI lingaphansi kwezinga lokushisa le-ambient ngaphakathi kwe-3 Kelvin (elilingana no-3℃), ikhwalithi ye-VI ipayipi ibhekwa njengeyamukelekayo.Ngakho-ke, uma umswakama wemvelo uphakeme kakhulu ngaleso sikhathi, lapho izinga lokushisa lepayipi le-VI lingaphansi kuka-3 Kelvin kusuka emvelweni, into yokufingqa kwamanzi nayo izokwenzeka.Idatha ethile iboniswa esithombeni esingezansi.

Isibonelo, uma umswakama we-ambient ungu-90% kanye nezinga lokushisa le-ambient lingu-27℃, izinga lokushisa elibalulekile lokwakheka kwamanzi ngalesi sikhathi lingu-25.67℃.Okusho ukuthi, lapho umehluko wezinga lokushisa phakathi kwepayipi le-VI nendawo ezungezile ingu-1.33 ℃, umcimbi wokufingqa kwamanzi uzovela.Kodwa-ke, umehluko wokushisa we-1.33 ℃ ungaphakathi kobubanzi obukhulu bepayipi le-VI, ngakho-ke akunakwenzeka ukuthuthukisa isimo sokufingqa kwamanzi ngokuthuthukisa ikhwalithi yepayipi le-VI.

Ngalesi sikhathi, siphakamisa ukuthi kwengezwe imishini yokususa umswakama, ukuvula iwindi ukuze kungene umoya, futhi kuncishiswe umswakama wemvelo, ukuze kuthuthukiswe ngempumelelo isimo sokufingqa kwamanzi.
