Ukuthuthwa nokugcinwa koketshezi lwe-cryogenic, ikakhulukazi i-liquid oxygen (LOX), kudinga ubuchwepheshe obuyinkimbinkimbi ukuze kuqinisekiswe ukuphepha, ukusebenza kahle, kanye nokulahlekelwa okuncane kwezinsiza.Vacuum amapayipi anejakhethi(I-VJP) iyingxenye ebalulekile kwingqalasizinda edingekayo ukuze kudluliswe okuphephile komoyampilo owuketshezi. Ngokugcina izinga lokushisa le-cryogenic le-LOX,vacuum jacketed amapayipizibalulekile ezinhlobonhlobo zezimboni, ezihlanganisa i-aerospace, yezokwelapha, kanye nemikhakha yegesi yezimboni.
Ayini amapayipi anejakhethi ye-Vacuum?
Vacuum amapayipi anejakhethiiqukethe ipayipi elingaphakathi elibamba uketshezi lwe-cryogenic, elizungezwe ijakhethi yangaphandle yokuvikela. Isikhala phakathi kwezingqimba ezimbili siyakhishwa ukuze kwakhiwe i-vacuum, enciphisa kakhulu ukudluliswa kokushisa kusuka endaweni yangaphandle kuya ku-cryogenic liquid. Lokhu kuvikela kuvimbela ukufudumala kwe-oksijini ewuketshezi, ngaleyo ndlela kunciphisa ingozi yokuhwamuka nokuqinisekisa ukuthi ihlala esimweni sayo samanzi ngesikhathi sokuthutha.
Kungani Amapayipi Ejakhethi Evacuum Abalulekile Ku-Liquid Oxygen
Umoya-mpilo owuketshezi uyagcinwa futhi uthuthwe emazingeni okushisa afinyelela ku -183°C (-297°F). Ngisho nokwenyuka okuncane kwezinga lokushisa kungabangela i-LOX ukuba ihwamuke, okuholela ekwakhekeni kwengcindezi, izingozi zokuphepha ezingaba khona, nokulahlekelwa izinto ezibalulekile.Vacuum amapayipi anejakhethiaklanyelwe ukunciphisa okokufaka ukushisa, ukuqinisekisa ukuthi umoya-mpilo owuketshezi uhlala uzinzile ngesikhathi sokuthutha amabanga amade noma emathangeni okugcina. Amakhono abo okufaka athuthukile asiza ukugcina isimo se-cryogenic se-LOX, okubenza babaluleke kakhulu ezinhlelweni zokusebenza lapho ukulawula izinga lokushisa okunembile kubalulekile.
Izinzuzo zamapayipi anejakhethi ye-Vacuum ye-Liquid Oxygen Systems
Ukusetshenziswa kwevacuum jacketed amapayipiinikeza izinzuzo eziningana ku-liquid oxygen transport systems. Okokuqala, bahlinzeka ngokushisa okuphakeme okushisayo uma kuqhathaniswa nezinto zendabuko, kunciphisa kakhulu ukudluliswa kokushisa nokuvimbela ukubilisa kwe-LOX. Lokhu kuholela ekusebenzeni okuphumelelayo futhi okungabizi kakhulu. Okwesibili, umklamo wevacuum jacketed amapayipiiqinisekisa ukugcinwa okuncane nokuphepha okuthuthukisiwe. Ngenxa yokuthi i-vacuum insulation inciphisa isidingo sokulungiswa njalo noma ukulungiswa, uhlelo luhlala luthembekile ngokuhamba kwesikhathi.
Ikusasa I-Outlook yamapayipi anejakhethi ye-Vacuum kuzicelo ze-LOX
Njengoba isidingo somoya-mpilo owuketshezi sikhula, ikakhulukazi emikhakheni efana nokunakekelwa kwezempilo (okuthola umoya-mpilo wezokwelapha) kanye nokuhlola indawo (yokuqhunyiswa kwamarokhethi),vacuum jacketed amapayipiizodlala indima ebalulekile ekuqinisekiseni ezokuthutha eziphephile nezisebenza kahle. Ngokuthuthuka okuqhubekayo ezintweni zokwakha kanye nokuklama, ikusasaipayipi le-vacuum jacketedizinhlelo zizosebenza kahle nakakhulu, zisize ukunciphisa izindleko zokusebenza ngenkathi kuthuthukiswa ukuphepha nokuthembeka kwe-LOX yokugcina nokusabalalisa.
Ekuphetheni,vacuum jacketed amapayipizibalulekile ekuthuthweni okuphephile komoya-mpilo owuketshezi. Ikhono labo lokuhlinzeka nge-insulation ephakeme nokugcina amazinga okushisa e-cryogenic abalulekile ekuvimbeleni ukulahlekelwa komoya-mpilo owuketshezi kanye nokuqinisekisa ukusebenza okuphephile, okuphumelelayo kuzo zonke izimboni ezihlukahlukene. Njengoba ukusetshenziswa kwe-oxygen oketshezi kwanda,vacuum jacketed amapayipiiyohlala iyisisekelo sengqalasizinda edingekayo ukusekela lesi sidingo esikhulayo.
