NGOHLELO LOKUPHAMBISA IJAkhethi EVACUUM
IVACUUM BAYONETUKUXHUMANATHAYIPHA NGEZINGEZI NAMABHUTI
Izinyathelo Zokufaka
Idatha ye-VJP(i-vacuum jacketd piping)kufanele ibekwe endaweni eyomile ngaphandle komoya ngaphambi kokufakwa.Ingaphandleukupakishaungqimba lwe-VJP alukwazibe vulaed, ukuvimbela ithubhu emizimbeni yangaphandle (isihlabathi, izinto eziphilayo ezincane, njll.). Uma lina noma isikhathi esidemanzisezulu, futhi kudingeka banake ngokukhethekile ngaphakathi ipayipi amanzi.
Akuvunyelwe ukusebenzisa i-VJP ngqo njenge-electrode yokushisela, shaya arcnoma ukushisela ku-VJP.
Idatha ye-VJPukupakishaungqimba alukwazi ukususwa kuze kube yilapho ipayipi ifakiwe ukuvimbela ukuwohloka kwe-welding kwezinye izikhundla.
Phakathi nayo yonke inqubo yokufaka, i-VJP kufanele isingathwe ngokucophelela. Vikela zombili iziphethoye-VJP, ungasebenzisi ivacuumokuhlangene ku-VJP (umdwebo 1 no-3) njengendawo yokuphoqelela ukuvimbela ukuvuza kwe-vacuum.
Lapho ufaka, qaphela ukwethembeka kokuphakanyiswa, ungawi futhi ulimaze noma ulimale.
Izinyathelo Zokufaka I-VJP
1. Hlolaiumdwebos, noma ngabe inani kanye nobukhuluwamapayipiemidwebeni ziyefanangeiamapayipi endle. BNgaphambi kokufaka, tholangaphandleI-VJP ngayinye ngokusho komdwebo kanyeinombolo. Isibonelo:HL2018I-GLN-59-02-01, okusho ukuthi ikhodi yephrojekthi ingu-59, i-liquid nitrogen medium, ipayipiCha.01 emgqeniCha.02. I-nameplate yensimbi enalokhuinomboloinamathiselwe ku-VJP endaweni (umfanekiso 1), futhi i-nameplate yokugqwala kagesi inamathiselweeduze kwejoyinti levacuumiI-VJP(umfanekiso 2).
Qaphela: iubuningikanye No.wamapayipi emdwebeni kufanele afane neubuningifuthiCha.kweAma-VJPsendaweni. Uma kukhona ukushayisana ekuhloleni, qiniseka ukuthi uthintana nabasebenzi bethu esizeni.
2. Ngemva kokuhlola ubuningi be-VJP kanyeCha.,ngokwemidwebo, hambisai-VJPskubakaki abahambisanayos/izisekelonoma indawoAma-VJPsphansi eduze kukabakaki abahambisanayos/izisekelo.
3. Ngaphambi kokuthi ama-flange axhunywe, qala uhlole ukuthi izindandatho zophawu neyunithi yophawu olubandayo zifakwe kahle yini.
4. Hlanza amalungaowesifazane & owesilisaisandisoipayipi, uphawuizindandathokanye neyunithi yophawu olubandayo ene-reagent engenawo uwoyela futhi engenamanzi.
5. Faka ipayipi lokunweba owesilisa nowesifazane ngokuvundlile futhi kancane. Bese udonsa ama-flange amabili ndawonye bese ucindezela, futhi ufake wonke amabhawodi kuma-flange (ungawaqinisi njengamanje).
6. Ngemuva kokuqinisekisa indawo efanele yama-flange amabili, qinisa ama-bolts isinyathelo ngesinyathelo. Qinisekisa ukuthi i-flange igcinwa isezingeni ngesikhathi sokufakwa
7. Hlola ukuthi ukuqiniswa kwe-flange kuyafaneleka yini.
8. IIsikhawu sokusekela okubili yi-3m, ipuleti le-PTFE kufanele lifakwe phakathi kwendawo yokusekela kanyengaphandleipayipi.
Imininingwane Yokusebenza Nokulungisa
1. Abasebenzi kufanele bajwayelane ne-umsebenziukugelezas phakathi kwezinto ezisetshenziswa ohlelweni. Kufanele kwaziwe ukuthi i-oksijeni ye-liquid, i-nitrogen eyi-liquid ne-argon ye-liquid yi-cryogenic liquids. Uma izinga lokushisa le-ambient liphakeme kunephoyinti lokubilisa, lizoba ngokwemvelogasifyfuthi icindezelekile, okuholela ekwenyukeni kancane kancane kwengcindezi ku-VJP nokunye okuhlobeneimishini.
2. Ukupholisa kuqala kwe-VJP ngaphambi kokusetshenziswa
Njengoba i-VJP engasetshenziswanga isezingeni lokushisa elizungezile, ipayipi ligcwele umoya oqukethe umswakama. Ngakho-ke, inhloso yokupholisa kwangaphambili: okokuqala, ukunciphisa kancane kancane izinga lokushisa le-VJP ekushiseni kwe-cryogenic liquid, ukuze ugweme ukuthintana okuqondile kwenani elikhulu le-cryogenic liquid nepayipi lokushisa elivamile, elikhiqiza ngokushesha. kanye nenani elikhulu le-gasification, okuholela ekucindezelekeni okusheshayo kwe-VJP, ngaleyo ndlela kubangele ukulimala kwe-VJP kanye nemishini yoketshezi yokugcina. Okwesibili, ukususa kancane kancane umoya ngaphakathi kwe-VJP nokugwema inani elikhulu le-cryogenic liquid ukuthintana ngqo nomoya, okuholela emakhazeni nokuvinjelwa ngaphakathi kwe-VJP.
Ngaphambi kokusetshenziswa kabusha kwepayipi le-vacuum adiabatic ngemva kokusetshenziswa kokuqala noma ukukhiqizwa kokumisa, ukupholisa kuqala kufanele kwenziwe ukuze ipayipi ye-vacuum adiabatic isebenze ngokujwayelekile kuphela ngemva kokuba ifinyelele esimweni sokusebenza.
3. IIndlela Yokupholisa Ngaphambiliwe VJP
Okokuqala, hlola ukuthi i-valves, isilinganiso somfuthoskanye ne-valve yokuphephas njll.ohlelweni lwe-VJP zisesimweni esihambisanayo esijwayelekile. Ngemva kwalokhu okungenhlahlolakuqediwe, vula kancanei-valve yokungena yesistimu ye-VJPbese uyahwamuka/gasifyuketshezi olugeleza kancane lungene emoyeni opholile ukuya ngaphambili-pholile iI-VJPokwemayelanaImizuzu engama-30. Ingcindezi kuI-VJPiyashintshashintsha kakhulungalesi sikhathi.Lapho ingcindezi kuI-VJPlizinza, ivolumu yokumnika inganyuswa kancane kancane ize ihlangabezane nezidingo.(Qaphela: ngesikhathi senqubo yokupholisa ngaphambilini, uma ingcindezi ku-I-VJPiphakeme kunengcindezi yokuklama ehambisanayo,kufanele kube ngokusheshawemaukumnika ohlelweni lwe-VJP.Mokwamanje,vula ngokupheleleumoyai-valvesemgqeni wokukhulula ingcindezi.)
4. Shlala PhansiI-VJP
Lapho umisa ukumnika, akuvunyelwe ngokuqinile ukuvala ama-valve azo zombili iziphetho zesistimu ye-VJP ngasikhathi sinye, ukuze kwakhiwe isimo esivaliwe endaweni.I-VJPuhlelo, okuholela ekucindezelekeni ngokweqile koketshezi oluyinsalela ku-VJPngenxa ye-gasification.
5. Izikhathi ezithileDukukhishwa kweCi-ryogenicLama-iquids (LiquOi-oksijeni Kuphela)
Ngoba ama-hydrocarbons nezinsalela zikhonaI-VJP yeumoya-mpilo owuketshezi, lezi zinto zizofakwa epayipini elingaphakathi isikhathi eside lapho zithuthwa nge-I-VJP.Uma ama-hydrocarbon efakwe epayipini ngobuningi futhi isikhathi eside, njengoba isimo sezulu sishisa nomaukukhiqizwa kwei-oxygen ewuketshezi yi-stopped, ukugcwala kwama-hydrocarbons kuI-VJPukwanda, futhi ukusabela nge-oxygen esele kungabangelaanqhumaumbono.
6.UkuphephaDevicewe VJP
Kulelo naleloI-VJPuhlelo kufanele lusethelwe uhlelo lokukhipha ukuphepha (okuhlanganisa i-valve yokusiza kanye ne-valve ye-vent), Lapho ingcindezi ye-VJP ifinyelela ukucindezela kokuvula ama-valve okuphepha okuzovula ngokuzenzakalelayo futhi akhulule ukucindezela ngesikhathi. Ngesikhathi esifanayo, i-umoyaama-valve nawo angavulwa ngesandla ukuze akhulule ingcindezi yokuqinisekisa ukuphepha kwalo lonke uhlelo lwe-VJP.
Ukungasebenzi kanye Nokulahlwa
| KungenzekaBama-reakdowns | Isizathu | Ukuphatha |
| Ingcindezi ekhuphukayo idala iukuphephai-valve ukuze iqale ngokuqhubekayo. | Ama-valve emikhawulweni yomibili ye-I-VJPzivaliwe kanyekanye, Dala ingcindezi ikhuphuke. | Ngokushesha vula ama-valve kuzo zombili iziphetho ze-I-VJPukuze unciphise ingcindezi, bese uvula iumoyai-valvesngesikhathi esifanayo. |
| Ukufakwa kwepayipi okuvinjiwe. | Kukhona okuvimbileku-VJP. | Vuthela iI-VJPngegesi ye-nitrogen.(Ice ukuvimbela: Vuthela nge-100oC nitrogen gas) |
