Izindlela zokufaka
I-VJP(I-vacuum jacketed piping)kufanele ibekwe endaweni eyomile ngaphandle komoya ngaphambi kokufakwa.Le khasi-ngaphandle njeukuwowaphaungqimba lwe-vjp alikwazibe vulaed, ukuvikela ishubhu ibe yizinto zakwamanye amazwe (isihlabathi, izidalwa ezincane, njll.). Emvuleni noma isikhathi eside-manziIsimo sezulu, futhi kudingeka sinake ngokukhethekile ngaphakathi kwe-Pipeline materproof.
Kwenqatshelwe ukusebenzisa i-VJP ngqo njenge-Welding Electrode, shaya i-arcnoma i-welding ku-vjp.
I-VJPukuwowaphaIsendlalelo asikwazi ukususwa kuze kube yilapho ipayipi lifakiwe ukuvikela ukuwohloka kwe-welding kwezinye izikhundla.
Ngesikhathi senqubo yonke yokufaka, i-VJP kufanele iphathwe ngokucophelela. Vikela imiphetho yomibiliye-VJP, ungasebenzisimba okuvubalisa ndawonyeIhlanganiswe ku-VJP (Umdwebo 1 no-3) njengephuzu lamandla ukuvikela ukuvuvukala kwe-vacuum.
Lapho ufaka, naka ukuthembeka kokuthuthumela, ungawi futhi ulimaze noma ulimale.
Izinyathelo zokufaka ze-VJP
1. -Hlolale khasiumbhalos, Ukuthi inani kanye nobukhuluamapayipiEmidwebeni ziyefanane-le khasiAmapayipi ensimu. BUkufakwa, tholangaphandlei-vjp ngayinye ngokuya ngomdwebo futhiinombolo. Isibonelo:HLNgo-2018Nimnyama-59-02-01, okusho ukuthi ikhodi yephrojekthi ingu-59, i-nitrogen ye-nitrogen, ipayipiCha.01 komugqaCha.02. I-newplate yensimbi nalokhuinomboloinamathiselwe kwi-VJP esizeni (Umdwebo 1), kanye negama likagesi likagesi linamathiselweeduze kwe-vacuum ehlanganisiwele khasiI-VJP(Umdwebo 2).
Qaphela: Theubuningifuthi cha.amapayipi emdwebeni kumele afane neubuningina-Cha.iwa-I-VJPSendaweni. Uma kukhona ukungafani kokuhlola, qiniseka ukuthi uxhumana nabasebenzi bethu esizeni.
2. Ngemuva kokubheka inani le-VJP futhiCha.,ngokwemidwebo, hambisaI-VJPsku-bracket ehambisanayoS / Supportsnoma indawoI-VJPSEmhlabathini eduze kwabakaki ehambisanayoS / Supports.
3. Ngaphambi kokuba ama-flanges axhunyiwe, qala uhlole ukuthi ngabe izindandatho zesilendi kanye nophiko lwamakhaza zifakiwe kahle
4. Hlanza amalunga weOwesifazane & Owesilisaukunwebaipayipi, sealizindandathokanye neyunithi elibandayo elinamakhaza nge-reagent engenawo-uwoyela futhi engenamanzi.
I-5. Faka ipayipi labesilisa nangowesifazane ngokuqondile nangokuhamba kancane. Bese udonsa ama-flanges amabili ndawonye bese ucindezela, bese ufaka wonke ama-bolts kuma-flanges (ungazenzeki manje).
6. Ngemuva kokuqinisekisa isikhundla esifanele sama-flanges amabili, qinisa ama-bolts step ngesinyathelo. Qinisekisa ukuthi i-flange igcinwe izinga ngesikhathi sokufakwa
7. Bheka ukuthi ukuqinisa i-flange kuyafaneleka yini.
8. TheIsikhashana sokusekelwa okubili yi-3M, ipuleti le-PTFE kufanele lifakwe phakathi kwephuzu lokusekelwa futhi-ngaphandle njeipayipi.
Imininingwane yokusebenza nokulungiswa
1. Opharetha kufanele bajwayelaneumsebenzithuntululekas phakathi kwemishini ohlelweni. Kufanele kwaziwe ukuthi umoya-mpilo owuketshezi, i-nitrogen ye-liquid ne-argon ewuketshezi yi-crygenic ketshezi. Lapho izinga lokushisa elizwakalayo liphakeme kunephuzu elibilayo, zizoba ngokwemvelo-shiselelekilefuthi wacindezela, okuholela ekukhuphukeni kancane kancane ekucindezelweni kuVjp nokuhlobeneimishini.
2. Ukuqanjwa kwe-VJP ngaphambi kokusebenzisa
Njengoba i-VJP engasetshenziswanga izokushisa okukhona, ipayipi ligcwele umoya oqukethe umswakama. Ngakho-ke, inhloso yokupholisa kwangaphambili ukuthi: Okokuqala, ukunciphisa kancane kancane izinga lokushisa le-VJP ekushiseni koketshezi lwe-cryogenic, ukuze ugweme ukuxhumana okuqondile kwenani elikhulu le-cryogenic, kukhiqiza ngokushesha kanye nenani elikhulu le-sosication, okuholele ekucindezelweni okusheshayo kwe-VJP, ngaleyo ndlela kubangele ukulimala kwe-VJP kanye nemishini yotshwala ye-terminal. Okwesibili, ukukhetha kancane kancane komoya ngaphakathi kwe-VJP futhi uvikele inani elikhulu le-cryogenic liquid ukuxhumana ngqo nomoya, okuholela ekukholweni nasekuvinjelweni ngaphakathi kwe-VJP.
Ngaphambi kokusetshenziswa kabusha kwepayipi le-vacuum adiabatic ngemuva kokusetshenziswa kokuqala noma ukuyeka ukukhiqizwa, ukuvezwa kuzokwenziwa ukuze ipayipi le-adiabatic adiabatic lingasebenza ngokujwayelekile ngemuva kokuthi lifinyelele esimweni esisebenzayo.
3. Le khasiIndlela yokuqalisaye-vjp
Okokuqala, hlola ukuthi ngabe i-valves, Ingcindezi Gaugesne-valve yokuphephas njll.Ohlelweni lwe-VJP lusesimweni esijwayelekile esijwayelekile. Ngemuva kwalokhu okungenhla-hlolakuqediwe, vula kancaneI-Inlet valve yohlelo lwe-VJPkanye ne-vaporize/ Gciciltuketshezi olungaphansi lube umoya opholile ukuze ufike ngaphambili-kupholeI-VJPingomanemaqondanaImizuzu engama-30. Ingcindezi kuI-VJPziguquguquka kakhulungalesi sikhathi.Lapho ingcindezi kuI-VJPIba izinzile, ivolumu yokumnika ingandiswe kancane kancane ize ihlangabezane nezidingo.(Qaphela: Ngesikhathi senqubo yangaphambi kokupholisa, uma ingcindezi kuI-VJPiphakeme kunengcindezi yokuqamba ehambisanayo,kumele kube ngokusheshawemaukumnika ohlelweni lwe-VJP.MU-EANNasele,Vula ngokupheleleisikhalaisivalwanasemgqeni wokukhipha ingcindezi.)
4. UshikukaziHut phansiI-VJP
Lapho umisa ukumnika, kuvinjelwe ngokuphelele ukuvala ama-valves ezinhlamvu zombili zohlelo lwe-VJP ngasikhathi sinye, ukuze wakhe umbuso ovaliwe kuI-VJPuhlelo, okuholele ekucindezelweni ngokweqile koketshezi oluyinsalela ku-VJPngenxa yegesi.
5. -Ngesikhathi esithileDlixilay ofCryogenicLama-iquid (LiidOxygen kuphela)
Ngoba ama-hydrocarbons nezinsalela zikhonaVjp yeumoya-mpilo owuketshezi, lezi zinto zizofakwa kwipayipi elingaphakathi isikhathi eside lapho lihanjiswa kuVjp.Lapho ama-hydrocarbons efakwa ku-tube ngamanani amakhulu futhi isikhathi eside, njengoba isimo sezulu sishisa phezulu nomaukukhiqizwa kweI-oxygen ewuketshezi is Stoxunya, ukugcwala kwama-hydrocarbons kuI-VJPkuyanda, futhi ukusabela nge-oksijini esele kungadalaan-eyisasion.
6.UkuphephaDubuqhazaye-vjp
Kuwo wonkeI-VJPIsistimu kufanele isethwe uhlelo lokukhipha ukuphepha (kufaka phakathi i-valve yokusiza kanye ne-vent valve), lapho ingcindezi ye-VJP ifinyelela ingcindezi yokuvula yama-valves okuphepha azovula ngokuzenzakalelayo futhi akhulule ingcindezi ngesikhathi. Ngasikhathi sinye,isikhalaAma-valves nawo angavulwa ngesandla ukukhipha ingcindezi yokuqinisekisa ukuphepha kohlelo lonke lwe-VJP.
Ukungasebenzi kahle nokulahlwa
