Inqubo yokupholisa kuqala yepayipi

Kuyo yonke inqubo yokudluliswa kwepayipi le-cryogenic liquid, ngaphambi kokusungula isimo sokudlulisela esizinzile, kuzoba nesistimu yokupholisa ngaphambili nokushisayo kanye nenqubo yokwamukela imishini, okungukuthi, inqubo yokupholisa ngaphambili. Kule nqubo, ipayipi kanye nemishini yokwamukela ukumelana nokucindezeleka okukhulu kokuncipha kanye nokucindezela komthelela, ngakho kufanele kulawulwe.

Ake siqale ngokuhlaziywa kwenqubo.

Yonke inqubo yokupholisa kuqala iqala ngenqubo yokuhwamuka okunodlame, bese kuvela ukugeleza kwezigaba ezimbili. Ekugcineni, ukugeleza kwesigaba esisodwa kuvela ngemva kokuba isistimu isipholile ngokuphelele. Ekuqaleni kwenqubo yokupholisa, izinga lokushisa lodonga ngokusobala lidlula izinga lokushisa lokugcwala kwe-cryogenic liquid, futhi lidlula izinga lokushisa eliphezulu elilinganiselwe loketshezi lwe-cryogenic - izinga lokushisa elishisa kakhulu. Ngenxa yokudlulisa ukushisa, uketshezi oluseduze nodonga lweshubhu luyashiswa futhi luvuthwe ngokushesha ukuze lwenze ifilimu yomhwamuko, ezungeza ngokuphelele udonga lwamashubhu, okungukuthi, ukubiliswa kwefilimu kwenzeka. Ngemuva kwalokho, ngenqubo yokupholisa kuqala, izinga lokushisa lodonga lwamashubhu liyehla kancane kancane ngaphansi komkhawulo wokushisa okuphezulu, bese kwakheka izimo ezivumayo zokubilisa kwenguquko kanye nokubilisa kwe-bubble. Ukushintshashintsha kwengcindezi enkulu kwenzeka phakathi nale nqubo. Lapho ukupholisa kuqala kwenziwa esigabeni esithile, amandla okushisa epayipi kanye nokuhlasela kokushisa kwemvelo ngeke kushise uketshezi lwe-cryogenic ekushiseni kokugcwala, futhi isimo sokugeleza kwesigaba esisodwa sizovela.

Enqubweni yokuhwamuka okukhulu, ukugeleza okumangalisayo nokuguquguquka kwengcindezi kuzokwenziwa. Kuyo yonke inqubo yokuguquguquka kwengcindezi, ingcindezi ephezulu eyenziwe okokuqala ngemuva kokuthi uketshezi lwe-cryogenic lungene ngqo epayipini elishisayo yilona amplitude enkulu kuyo yonke inqubo yokuguquguquka kwengcindezi, futhi igagasi lokucindezela lingaqinisekisa amandla okucindezela kwesistimu. Ngakho-ke, igagasi lokuqala lokucindezela kuphela elifundwayo ngokuvamile.

Ngemva kokuvulwa kwevalvu, uketshezi lwe-cryogenic lungena ngokushesha epayipini ngaphansi kwesenzo somehluko wengcindezi, futhi ifilimu lomhwamuko elikhiqizwa ukuhwamuka kwehlukanisa uketshezi odongeni lwamapayipi, kwenze ukugeleza kwe-axial okugxilile. Ngenxa yokuthi i-coefficient yokumelana nomhwamuko incane kakhulu, ngakho-ke izinga lokugeleza koketshezi lwe-cryogenic likhulu kakhulu, ngokuqhubeka phambili, izinga lokushisa loketshezi ngenxa yokumuncwa kokushisa futhi likhuphuka kancane kancane, ngokufanele, ingcindezi yepayipi iyanda, isivinini sokugcwalisa sihamba kancane. phansi. Uma ipayipi lide ngokwanele, izinga lokushisa le-liquid kufanele lifinyelele ukugcwala ngesikhathi esithile, lapho uketshezi luyeka ukuqhubeka. Ukushisa okuvela odongeni lwamapayipi kuya oketshezini lwe-cryogenic konke kusetshenziselwa ukuhwamuka, ngalesi sikhathi isivinini sokuhwamuka sikhuphuka kakhulu, ukucindezela epayipini nakho kuyanda, kungase kufinyelele izikhathi ezingu-1. 5 ~ 2 zokucindezela kokungena. Ngaphansi kwesenzo somehluko wengcindezi, ingxenye yoketshezi izophindiselwa emuva ethangini lokugcina uketshezi lwe-cryogenic, okuholela ekutheni ijubane lokukhiqizwa komhwamuko libe lincane, futhi ngenxa yokuthi ingxenye yomhwamuko okhiqizwe ekuphumeni kokuphuma kwepayipi, ukwehla komfutho wepayipi, ngemva kwalokho. isikhathi esithile, ipayipi lizophinde limise uketshezi ezimweni zomehluko wengcindezi, lo mkhuba uzovela futhi, uphindaphindwe. Kodwa-ke, kule nqubo elandelayo, ngenxa yokuthi kukhona ukucindezela okuthile kanye nengxenye yoketshezi epayipini, ukunyuka kwengcindezi okubangelwa uketshezi olusha kuncane, ngakho ukuphakama kokucindezela kuzoba kuncane kunokuqala kokuqala.

Kuyo yonke inqubo yokupholisa kuqala, uhlelo alugcini nje kuphela ukuthi luthwale umthelela omkhulu wegagasi lokucindezela, kodwa futhi kufanele luthwale ukucindezeleka okukhulu kokuncipha ngenxa yamakhaza. Isenzo esihlangene salokhu okubili singabangela ukulimala kwesakhiwo ohlelweni, ngakho-ke izinyathelo ezidingekayo kufanele zithathwe ukuyilawula.

Njengoba izinga lokugeleza kwangaphambi kokupholisa lithinta ngokuqondile inqubo yokupholisa kwangaphambili kanye nobukhulu bokucindezeleka kokuncipha okubandayo, inqubo yokupholisa kuqala ingalawulwa ngokulawula izinga lokugeleza kwangaphambi kokupholisa. Umgomo onengqondo wokukhetha wezinga lokugeleza kokupholisa ngaphambi kokuba uphole uwukufinyeza isikhathi sokupholisa kuqala ngokusebenzisa izinga lokugeleza elikhulu lokupholisa ngaphambi kwesisekelo sokuqinisekisa ukuthi ukuguquguquka kwengcindezi nokuncipha kwamakhaza akudluli uhla oluvumelekile lwezisetshenziswa namapayipi. Uma izinga lokugeleza kwangaphambi kokupholisa lilincane kakhulu, ukusebenza kokufakwa kwamapayipi akulilungele ipayipi, lingase lingafinyeleli esimweni sokupholisa.

Enkambweni yokupholisa kuqala, ngenxa yokuvela kokugeleza kwezigaba ezimbili, akunakwenzeka ukukala izinga lokugeleza langempela nge-flowmeter evamile, ngakho-ke ngeke isetshenziselwe ukuqondisa ukulawulwa kwezinga lokugeleza kwangaphambi kokupholisa. Kodwa singahlulela ngokungaqondile ubukhulu bokugeleza ngokuqapha ingcindezi yangemuva yomkhumbi owamukelayo. Ngaphansi kwezimo ezithile, ubuhlobo phakathi kwengcindezi yangemuva yomkhumbi owamukelayo kanye nokugeleza kwangaphambi kokupholisa kunganqunywa ngendlela yokuhlaziya. Uma inqubo yokupholisa kuqala iqhubekela esimweni sokugeleza kwesigaba esisodwa, ukugeleza kwangempela kukalwa nge-flowmeter kungasetshenziswa ukuqondisa ukulawulwa kokugeleza kokupholisa kwangaphambili. Le ndlela ivame ukusetshenziselwa ukulawula ukugcwaliswa kwe-cryogenic liquid propellant ye-rocket.

Ukuguqulwa kwengcindezi yangemuva yomkhumbi owamukelayo kuhambisana nenqubo yokupholisa kuqala kanje, engasetshenziselwa ukwahlulela ngokufanele isigaba sokupholisa: lapho umthamo wokukhipha umkhumbi owamukelayo uhlala njalo, ingcindezi yangemuva izokhula ngokushesha ngenxa yobudlova. ukuhwamuka koketshezi lwe-cryogenic ekuqaleni, bese kancane kancane wehla ngokuncipha kwezinga lokushisa lomkhumbi owamukelayo kanye nepayipi. Ngalesi sikhathi, amandla okupholisa ayanda.
