Ezweni lama-cryogenics, isidingo sokuvikela ukushisa okusebenzayo nokuthembekile sibaluleke kakhulu, ikakhulukazi uma kukhulunywa ngokuthuthwa koketshezi olupholile njenge-helium ewuketshezi.Amapayipi anejakethi yokuhlanza(VJP) ubuchwepheshe obuyinhloko ekunciphiseni ukudluliselwa kokushisa nokuqinisekisa ukuthi uketshezi oluyi-cryogenic njenge-helium ewuketshezi luhlala emazingeni okushisa aphansi afunekayo ngesikhathi sokuthuthwa. Lesi sihloko sihlola indima ebalulekile yamapayipi anejakethi ye-vacuum ekusetshenzisweni kwe-helium ewuketshezi.

Ayini Amapayipi Afakwe Ijekethi Ye-Vacuum?

Amapayipi anejakethi yokuhlanza, eyaziwa nangokuthi amapayipi afakwe umswakama, amapayipi akhethekile anesendlalelo sokuvimbela umswakama phakathi kwezindonga ezimbili zamapayipi eziqinile. Le sendlalelo sokuvimbela umswakama sisebenza njengesivikelo sokushisa esisebenza kahle kakhulu, sivimbela ukudluliselwa kokushisa kuye noma kusuka kokuqukethwe kwepayipi. Nge-helium ewuketshezi, ebilisa ekushiseni okucishe kube ngu-4.2 Kelvin (-268.95°C), ukugcina amazinga okushisa aphansi kangaka ngesikhathi sokuthutha kubalulekile ukugwema ukuhwamuka nokulahleka kwezinto.

Ukubaluleka Kwamapayipi Afakwe Ijekethi Ye-Vacuum Ezinhlelweni Ze-Helium Emanzi

I-helium ewuketshezi isetshenziswa kakhulu ezimbonini ezifana nokunakekelwa kwempilo (kwemishini ye-MRI), ucwaningo lwesayensi (kuma-accelerator ezinhlayiya), kanye nokuhlola isikhala (ukupholisa izingxenye zemikhumbi-mkhathi). Ukuthutha i-helium ewuketshezi kumabanga ngaphandle kokwenyuka okukhulu kwezinga lokushisa kubalulekile ekunciphiseni imfucuza nokuqinisekisa ukusebenza kahle kwenqubo.Amapayipi anejakethi yokuhlanzazenzelwe ukugcina uketshezi lusezingeni lokushisa elidingekayo ngokunciphisa kakhulu ukushintshana kokushisa.

Ukuncipha Kokutholakala Kokushisa Nokulahlekelwa Kokuhwamuka Komoya

Enye yezinzuzo eziyinhloko ze-amapayipi anejakethi ye-vacuumEzinhlelweni ze-helium eziwuketshezi yikhono lazo lokuvimbela ukungena kokushisa. Isendlalelo se-vacuum sinikeza isithiyo esicishe sibe siphelele emithonjeni yokushisa yangaphandle, okunciphisa kakhulu amazinga okubila. Lokhu kubalulekile ekugcineni isimo se-helium siwuketshezi ngesikhathi sokuthuthwa amabanga amade. Ngaphandle kokusebenzisa i-vacuum insulation, i-helium izonyamalala ngokushesha, okuholela ekulahlekelweni kwezimali kanye nokungasebenzi kahle kokusebenza.

Ukuqina Nokuguquguquka

Amapayipi anejakethi yokuhlanzaEzisetshenziswa ezinhlelweni ze-helium eziwuketshezi zenzelwe ukuqina, zivame ukwakhiwa ngensimbi engagqwali noma ezinye izinto ezingamelana namazinga okushisa aphezulu kanye nokucindezeleka komshini. Lawa mapayipi aphinde abe nemiklamo eguquguqukayo, okuvumela ukufakwa okulula ezinhlelweni ezingadinga izindlela ezigobile noma eziguquguqukayo. Lokhu kuguquguquka kuwenza afaneleke kakhulu engqalasizinda eyinkimbinkimbi njengezindawo zokucwaninga, amathangi okugcina izinto ezicijile, kanye namanethiwekhi okuthutha.

Isiphetho

Amapayipi anejakethi yokuhlanzaidlala indima ebalulekile ekuthuthweni kwe-helium ewuketshezi, inikeza ukuvikelwa kokushisa okusebenzayo kakhulu okunciphisa ukutholakala kokushisa futhi kunciphise ukulahleka. Ngokulondoloza ubuqotho bezinto ezikhipha uketshezi, la mapayipi asiza ekulondolozeni i-helium eyigugu futhi anciphise izindleko zokusebenza. Njengoba izimboni ziqhubeka nokusungula izinto ezintsha futhi zidinga izinhlelo ezithuthukisa uketshezi, indima yalokhuamapayipi anejakethi ye-vacuumkuzokhula kuphela ngokubaluleka. Ngokusebenza kwazo okungenakuqhathaniswa kokushisa nokuqina,amapayipi anejakethi ye-vacuumisalokhu ingubuchwepheshe obubalulekile emkhakheni we-cryogenics, ikakhulukazi ekusetshenzisweni kwe-helium ewuketshezi.

Ekuphetheni,amapayipi anejakethi ye-vacuum(VJP) zibalulekile ekusetshenzisweni kwe-helium ewuketshezi, okuvumela ukuthuthwa okuphumelelayo, ukunciphisa imfucuza, kanye nokuqinisekisa ukuphepha nokuthembeka kwezinhlelo ze-cryogenic.
