Ukuthuthwa nokugcinwa koketshezi oluyi-cryogenic, ikakhulukazi i-liquid oxygen (LOX), kudinga ubuchwepheshe obuthuthukisiwe ukuqinisekisa ukuphepha, ukusebenza kahle, kanye nokulahlekelwa okuncane kwezinsizakusebenza.Amapayipi anejakethi yokuhlanza(VJP) ziyingxenye ebalulekile engqalasizinda edingekayo ukuze kudluliselwe umoya-mpilo owuketshezi ngokuphephile. Ngokulondoloza izinga lokushisa le-LOX elikhanyayo,amapayipi anejakethi ye-vacuumzibalulekile ezinhlobonhlobo zezimboni, okuhlanganisa imikhakha yezindiza, yezokwelapha kanye negesi yezimboni.
Ayini Amapayipi Afakwe Ijekethi Ye-Vacuum?
Amapayipi anejakethi yokuhlanzaiqukethe ipayipi langaphakathi elibamba uketshezi oluyi-cryogenic, elizungezwe ijazi lokuvikela langaphandle. Isikhala esiphakathi kwezingqimba ezimbili siyasuswa ukuze kudalwe i-vacuum, okunciphisa kakhulu ukudluliselwa kokushisa kusuka endaweni yangaphandle kuya kuketshezi oluyi-cryogenic. Lokhu kuvikela kuvimbela ukufudumala komoya-mpilo owuketshezi, ngaleyo ndlela kunciphisa ingozi yokuhwamuka futhi kuqinisekise ukuthi uhlala usesimweni sawo soketshezi ngesikhathi sokuthuthwa.
Kungani Amapayipi Anejakhethi Ye-Vacuum Ebalulekile Ku-Oxygen Ewuketshezi
I-oksijini ewuketshezi igcinwa futhi ithuthwe emazingeni okushisa aphansi njengo-183°C (-297°F). Ngisho nokwenyuka okuncane kwezinga lokushisa kungabangela ukuthi i-LOX ishise, okuholela ekunqwabelaneni kwengcindezi, izingozi zokuphepha ezingaba khona, kanye nokulahlekelwa izinto eziyigugu.Amapayipi anejakethi yokuhlanzazenzelwe ukunciphisa ukufakwa kokushisa, ukuqinisekisa ukuthi i-oxygen ewuketshezi ihlala izinzile ngesikhathi sokuthuthwa ibanga elide noma ematangini okugcina. Amakhono azo okushisa athuthukisiwe asiza ekugcineni isimo se-LOX sicacile, okwenza zibe yinto ebalulekile lapho ukulawulwa kokushisa okunembile kubalulekile khona.
Izinzuzo Zamapayipi Afakwe Ijekethi Ye-Vacuum Yezinhlelo Zomoya-mpilo Owuketshezi
Ukusetshenziswa kweamapayipi anejakethi ye-vacuuminikeza izinzuzo eziningana ezinhlelweni zokuthutha umoya-mpilo owuketshezi. Okokuqala, zihlinzeka ngokushisa okuphezulu uma kuqhathaniswa nezinto zendabuko, zinciphisa kakhulu ukudluliselwa kokushisa futhi zivimbele ukubila kwe-LOX. Lokhu kuholela ekusebenzeni okuphumelelayo nokungabizi kakhulu. Okwesibili, ukwakheka kweamapayipi anejakethi ye-vacuumkuqinisekisa ukulungiswa okuncane kanye nokuphepha okuthuthukisiwe. Ngenxa yokuthi ukufakelwa kwe-vacuum kunciphisa isidingo sokulungiswa noma ukulungiswa njalo, uhlelo luhlala luthembekile ngokuhamba kwesikhathi.
Umbono Wesikhathi Esizayo Wemibhobho Egqokwe Nge-Vacuum kuzinhlelo zokusebenza ze-LOX
Njengoba isidingo se-oxygen ewuketshezi sikhula, ikakhulukazi emikhakheni efana nokunakekelwa kwempilo (ye-oxygen yezokwelapha) kanye nokuhlola isikhala (sokuqhutshwa kwamarokhethi),amapayipi anejakethi ye-vacuumkuzodlala indima ebalulekile ekuqinisekiseni ukuthuthwa okuphephile nokusebenza kahle. Ngokuthuthuka okuqhubekayo ezintweni zokwakha kanye nokuklama, ikusasaipayipi elinejakethi ye-vacuumizinhlelo zizosebenza kahle kakhulu, zisize ekunciphiseni izindleko zokusebenza ngenkathi zithuthukisa ukuphepha nokuthembeka kwesitoreji nokusatshalaliswa kwe-LOX.
Ekuphetheni,amapayipi anejakethi ye-vacuumzibalulekile ekuthuthweni okuphephile komoya-mpilo owuketshezi. Amandla azo okuhlinzeka ngokuvikela okuphezulu nokugcina amazinga okushisa acwebezelayo abalulekile ekuvimbeleni ukulahleka komoya-mpilo owuketshezi nokuqinisekisa ukusebenza okuphephile nokusebenza kahle kuzo zonke izimboni ezahlukene. Njengoba ukusetshenziswa komoya-mpilo owuketshezi kukhula,amapayipi anejakethi ye-vacuumkuzohlala kuyitshe lesisekelo sengqalasizinda edingekayo ukusekela lesi sidingo esikhulayo.
