-Nombekileindawo yokuphundu

Ngokuthuthukiswa kobuchwepheshe be-cryogenic, imikhiqizo yotshwala ye-cryogenic ibidlala indima ebalulekile emikhakheni eminingi efana nomnotho wezwe, izivikelo zezwe kanye nocwaningo lwesayensi. Ukusetshenziswa koketshezi we-cryogenic kususelwa kwisitoreji esisebenzayo nesiphephile kanye nokuhamba kwemikhiqizo ye-cryogenic uketshezi, kanye nokuhanjiswa kwamapayipi kwe-cryogenic liquid kusebenza yonke inqubo yokugcina kanye nokuhamba. Ngakho-ke, kubaluleke kakhulu ukuqinisekisa ukuphepha nokuhanjiswa kwe-cryogenic liquid ukuhanjiswa kwepayipi. Ngokudluliswa koketshezi lwe-cryogenic, kuyadingeka ukufaka esikhundleni igesi epayipini ngaphambi kokudlulisela, ngaphandle kwalokho kungadala ukwehluleka okusebenzayo. Inqubo yokuqalisa iyisixhumanisi esingenakugwenywa enqubweni yokuhamba komkhiqizo we-cryogenic uketshezi. Le nqubo izoletha ukushaqeka okuqinile kwengcindezi neminye imiphumela emibi epayipini. Ngaphezu kwalokho, into egibele i-geyser epayipini elime mpo nasekusebenzeni okungazinzile kokusebenza kwamapayipi wepayipi, ukugcwalisa amanzi okuvuthwa kwamaphangi nokugcwaliswa kwe-valve ngemuva kwemiphumela nepayipi. Ngenxa yalokhu, leli phepha lenza ukucubungula okujulile ezinkingeni ezingenhla, futhi zinethemba lokuthola ikhambi ngokuhlaziywa.

Ukuthuthwa kwegesi emgqeni ngaphambi kokudluliselwa

Ngokuthuthukiswa kobuchwepheshe be-cryogenic, imikhiqizo yotshwala ye-cryogenic ibidlala indima ebalulekile emikhakheni eminingi efana nomnotho wezwe, izivikelo zezwe kanye nocwaningo lwesayensi. Ukusetshenziswa koketshezi we-cryogenic kususelwa kwisitoreji esisebenzayo nesiphephile kanye nokuhamba kwemikhiqizo ye-cryogenic uketshezi, kanye nokuhanjiswa kwamapayipi kwe-cryogenic liquid kusebenza yonke inqubo yokugcina kanye nokuhamba. Ngakho-ke, kubaluleke kakhulu ukuqinisekisa ukuphepha nokuhanjiswa kwe-cryogenic liquid ukuhanjiswa kwepayipi. Ngokudluliswa koketshezi lwe-cryogenic, kuyadingeka ukufaka esikhundleni igesi epayipini ngaphambi kokudlulisela, ngaphandle kwalokho kungadala ukwehluleka okusebenzayo. Inqubo yokuqalisa iyisixhumanisi esingenakugwenywa enqubweni yokuhamba komkhiqizo we-cryogenic uketshezi. Le nqubo izoletha ukushaqeka okuqinile kwengcindezi neminye imiphumela emibi epayipini. Ngaphezu kwalokho, into egibele i-geyser epayipini elime mpo nasekusebenzeni okungazinzile kokusebenza kwamapayipi wepayipi, ukugcwalisa amanzi okuvuthwa kwamaphangi nokugcwaliswa kwe-valve ngemuva kwemiphumela nepayipi. Ngenxa yalokhu, leli phepha lenza ukucubungula okujulile ezinkingeni ezingenhla, futhi zinethemba lokuthola ikhambi ngokuhlaziywa.

Inqubo yokuqalisa yepayipi

Kuyo yonke inqubo yokudluliselwa kwepayipi e-cryogenic, ngaphambi kokusungula isimo sokudlulisela esizinzile, kuzoba nohlelo lokupholisa kwangaphambili nolushisayo kanye nenqubo yokuthola imishini, okungukuthi, inqubo yangaphambi kokupholisa. Kule nqubo, ipayipi nokwamukela imishini yokubekezelela ukucindezela okuthe xaxa kwengcindezi kanye nengcindezi yomthelela, ngakho-ke kufanele ilawulwe.

Ake siqale ngokuhlaziywa kwenqubo.

Inqubo yonke yokuqalisa kabusha iqala ngenqubo enobudlova ye-vaporization, bese ivela ngokugeleza kwesigaba ezimbili. Ekugcineni, ukuhamba kwesigaba esisodwa kuvela ngemuva kokuthi uhlelo lupholile ngokuphelele. Ekuqaleni kwenqubo yokuvelela, izinga lokushisa lodonga ngokusobala lidlula amazinga okushisa alolokhi we-cryogenic, futhi angeqi ukushisa okuphezulu koketshezi lwe-cryogenic - izinga lokushisa lokugcina lokushisa ngokweqile. Ngenxa yokudluliswa kokushisa, uketshezi oluseduze nodonga lwe-tube lufudumele futhi ngaso leso sikhathi luhlukaniswe ukuze kwakhiwe i-vapor film, ezungeze ngokuphelele udonga lwe-tube, okungukuthi, ukubila kwefilimu kwenzeka. Emva kwalokho, ngenqubo yokuvelela, izinga lokushisa lodonga lweshubhu kancane luyehla ngaphansi kokushisa komkhawulo we-superheat, bese kuba nezimo ezithandekayo zokubilisa ukuguqulwa kwe-bubble. Ukushintshashintsha kwengcindezi enkulu kwenzeka ngesikhathi senqubo. Lapho ukuvezwa kwenziwa esigabeni esithile, umthamo wokushisa wepayipi kanye nokuhlasela kokushisa kwemvelo ngeke kushise uketshezi lwe-cryogenic kuya kumazinga okushisa agcwele, futhi kuzovela isimo sokuhamba kwesigaba esisodwa.

Esezinhlelweni zokwehla okukhulu, kuzokhiqizwa ukuguquguquka kokuguquguquka okumangazayo. Kuyo yonke inqubo yokuguquguquka kwengcindezi, ingcindezi ephezulu eyasungulwa okokuqala ngemuva kokuthi uketshezi lwe-cryogenic lungena ngqo ipayipi elishisayo ukuguquguquka kwengcindezi yonke inqubo. Ngakho-ke, kuphela igagasi lokuqala lokucindezela elivame ukufundwa.

Ngemuva kokuthi i-valve ivuliwe, uketshezi lwe-cryogenic ungena ngokushesha ngepayipi ngaphansi kwesenzo sokucindezela umehluko, futhi ifilimu ye-vapor ekhiqizwa yi-vapor Ngoba i-coefficient evumelanayo ye-vapor incane kakhulu, ngakho-ke izinga lokugeleza koketshezi lwe-cryogenic likhulu kakhulu, ngenqubekela phambili phambili, izinga lokushisa livele kancane ngenxa yokuvuka kokushisa ngenxa yokuvuka kancane, ijubane lokugcwalisa lincipha. Uma ipayipi lide ngokwanele, izinga lokushisa eliwuketshezi kufanele lifinyelele ku-saturation ngasikhathi esithile, lapho uketshezi luyeka ukuthuthuka. Ukushisa okuvela odongeni lwamapayipi ku-ketshezi lwe-cryogenic konke kusetshenziselwa ukuhwamuka, ngalesi sikhathi ijubane lokuhwamuka likhuphuke kakhulu, ukucindezela epayipini nakho kuyanda, kungafinyelela ku-1. 5 ~ 2 izikhathi zengcindezi yengcindezi ye-inlet. Ngaphansi kwesenzo somehluko wengcindezi, ingxenye yoketshezi izovuselelwa ethangini lesitoreji se-cryogenic, okuholela ekunciphiseni ukuphuma kwepapor, futhi ngemuva kwengxenye yokwehla, ipayipi lizophinda lisuse uketshezi emimonweni yomehluko wokucindezela, i-ntomon izovela futhi. Kodwa-ke, kule nqubo elandelayo, ngoba kunengcindezi ethile nengxenye yoketshezi epayipini, ukunyuka kwengcindezi okubangelwa uketshezi olusha kuncane, ngakho-ke inani eliphakeme lengcindezelo lizoba lincane kune-peak yokuqala.

Kuyo yonke inqubo yokuqalisa kabusha, uhlelo alugcini nje ngokuthwala umthelela omkhulu wengcindezi yegazi, kodwa futhi kufanele sithwale ingcindezi enkulu ye-shrinkage ngenxa yokubanda. Isenzo esihlanganisiwe salaba sobabili singadala ukulimala okuhlelekile kohlelo, ngakho-ke kufanele kuthathwe izinyathelo ezidingekayo zokuyilawula.

Njengoba izinga lokugeleza lokuhamba ngokuqondile lithinta ngqo inqubo yokuqalisa kanye nosayizi wokucindezela okubandayo kwe-shrinkage, inqubo yokuqalisa ingalawulwa ngokulawula isilinganiso sokugeleza okuvelele. Umgomo wokukhetha ofanele we-Preveoling Flow Rate ukufushanisa isikhathi sokuhamba kabusha ngokusebenzisa isilinganiso sokugeleza okuthe xaxa esisekelweni sokuqinisekisa ukuthi ukuguquguquka kwengcindezi nokucindezelwa okubandayo akudluleli uhla oluvumelekile lwemishini namapayipi. Uma izinga lokugeleza langaphambi kokupholisa lincane kakhulu, ukusebenza kwe-Pipeline insulation akukuhle ngepayipi, kungahle kungafinyelele esimweni sokupholisa.

Enqubweni yokuqoqa, ngenxa yokuvela kokugeleza kwesigaba ezimbili, akunakwenzeka ukukala isilinganiso sokugeleza kwangempela nge-flowmeter ejwayelekile, ngakho-ke akunakusetshenziselwa ukuqondisa ukuphathwa kwezinga lokuhamba kabusha. Kepha singahlulela ngokungaqondile usayizi wokugeleza ngokubheka ingcindezi engemuva yomkhumbi owamukelayo. Ngaphansi kwemibandela ethile, ubudlelwano phakathi kwengcindezi engemuva yesikebhe sokuthola nokugeleza kwangaphambi kokupholisa kunganqunywa ngendlela yokuhlaziya. Lapho inqubo yokuqalisa iqhubeka isesimweni sokugeleza kwesigaba esisodwa, ukugeleza kwangempela okulinganiswe yi-flowmeter kungasetshenziselwa ukuqondisa ukulawulwa kokugeleza okuvelayo. Le ndlela ivame ukusetshenziselwa ukulawula ukugcwaliswa kwe-cryogenic liquid propellant ye-rocket.

Ukushintshwa kwengcindezi yangemuva yesikebhe esamukelayo kufana nenqubo yokuqalisa ngokulandelayo, okungasetshenziswa ukwahlulela ngokungemthetho kwesikebhe, bese kuthi kancane kancane i-Prequap enokwehla ngenxa yokuncipha kwesikebhe kanye nepayipi. Ngalesi sikhathi, umthamo wokurefezwana ukhula.

Ihlelwe esihlokweni esilandelayo eminye imibuzo!

Imishini ye-HL Cryogenic

Imishini ye-HL Cryogenic eyasungulwa ngo-1992 ingumbano ohambisana ne-HL Cr Cryogenic Equipment Company Company Co, Ltd. Imishini ye-HL Crygenic izimisele ekwakhiweni nasekukhiqizweni kwesistimu ephezulu ye-CrCuum Ensuum Ensumed System kanye nemishini yokusekela ehlobene yokuhlangabezana nezidingo ezahlukahlukene zamakhasimende. I-Vacuum Insured Pipe ne-hose eguquguqukayo yakhiwa ngezinto zokwenziwa ezikhethekile eziphakeme nezinto eziningi ezikhethekile zokwelapha ezikhethekile, futhi zidlula ngochungechunge lwezindlela zokwelapha eziqinile kakhulu zokwelapha kanye nokwelashwa okuphezulu kwe-vacuum, esetshenziselwa i-hydrogen ye-ethylene, i-helium, i-helium ye-ethylene ges lng.
