NGOHLELO LOKUPHAPHA OLWE-VACUUM JACKETED
I-VACUUM BAYONETUXHUMANISOTHAYIPHA NGEZIMPAWU NAMABHOLTHI
Izinyathelo Zokuqapha Ukufakwa
I-VJP(ipayipi elinejakethi ye-vacuum)kufanele ibekwe endaweni eyomile engenamoya ngaphambi kokufakwa.Iyangaphandleukupakishwaungqimba lwe-VJP alukwazibe vulaed, ukuvimbela ithubhu ukungena emizimbeni yangaphandle (isihlabathi, izinto eziphilayo ezincane, njll.). Emvula noma isikhathi esidemanziisimo sezulu, futhi kudingeka unake kakhulu ingaphakathi lepayipi elingangeni manzi.
Akuvunyelwe ukusebenzisa i-VJP ngqo njenge-electrode yokushisela, i-strike arcnoma ukushisela ku-VJP.
I-VJPukupakishwaungqimba alukwazi ukususwa kuze kube yilapho ipayipi selifakiwe ukuvimbela ukuphuka kokushisela kwezinye izikhundla.
Ngesikhathi senqubo yonke yokufaka, i-VJP kufanele iphathwe ngokucophelelaVikela izinhlangothi zombiliye-VJP, ungasebenzisii-vacuumijoyinti ku-VJP (isithombe 1 no-3) njengendawo yamandla yokuvimbela ukuvuza kwe-vacuum.
Uma ufaka, naka ukuthembeka kokuphakamisa, ungawi futhi ungalimazi noma ulimele.
Izinyathelo Zokufaka ze-VJP
1. Ishekeiumdwebos, ukuthi inani kanye nobukhuluamapayipiemidwebweni ziyafanangeiamapayipi asensimini. Bngaphambi kokufakwa, tholaphandlei-VJP ngayinye ngokusho komdwebo kanyeinomboloIsibonelo:HL2018I-GLN-59-02-01, okusho ukuthi ikhodi yephrojekthi ingu-59, i-nitrogen medium ewuketshezi, ipayipiCha.01 yomugqaCha.02. Ipuleti lensimbi elinalokhuinomboloinamathiselwe ku-VJP endaweni (isithombe 1), futhi kunamathiselwe ipuleti legama lokugqwala kagesieduze kwe-vacuum jointiI-VJP(isithombe 2).
Qaphela: iubuningifuthi Cha.amapayipi akumdwebo kumele afane nalawoubuningifuthiCha.kweAma-VJPendaweni. Uma kukhona ukungafani ekuhlolweni, qiniseka ukuthi uxhumana nabasebenzi bethu endaweni.
2. Ngemva kokuhlola inani le-VJP kanyeCha.,ngokusho kwemidwebo, hambai-VJPskubhakede elihambisanayoizisekelo/izisekelinoma indawoAma-VJPphansi eduze kwebhulakhethi elihambisanayoizisekelo/izisekeli.
3. Ngaphambi kokuba ama-flange axhunywe, qala uhlole ukuthi amasongo okuvala kanye neyunithi yokuvala ebandayo kufakwe kahle yini
4. Hlanza amalungaowesifazane nowesilisaisandisoipayipiuphawuizindandathokanye neyunithi yokuvala ebandayo ene-reagent engenawoyela nengenamanzi.
5. Faka ipayipi lokwelula lesilisa nelesifazane ngokuvundlile nangokuhamba kancane. Bese udonsa ama-flange amabili ndawonye bese ucindezela, bese ufaka wonke amabhawodi kuma-flange (ungawaqinisi njengamanje).
6. Ngemva kokuqinisekisa indawo efanele yama-flange amabili, qinisa amabhawodi isinyathelo ngesinyathelo. Qinisekisa ukuthi i-flange igcinwa iqondile ngesikhathi sokufakwa
7. Hlola ukuthi ukuqinisa i-flange kuyafaneleka yini.
8. Iisikhawu sokusekela okubili singama-3m, ipuleti le-PTFE kufanele lifakwe phakathi kwendawo yokusekela kanyeyangaphandleipayipi.
Imininingwane Yokusebenza Nokulungisa
1. Abasebenzi kufanele bajwayelene ne-umsebenziukugelezas phakathi kwemishini ohlelweni. Kufanele kwaziwe ukuthi i-oxygen ewuketshezi, i-nitrogen ewuketshezi kanye ne-argon ewuketshezi kuyizinto ezibangela uketshezi oluyi-cryogenic. Uma izinga lokushisa elizungezile liphakeme kunezinga lokubila, zizoba ngokwemvelo.i-gasifyfuthi kucindezelwe, okuholela ekwandeni kancane kancane kwengcindezi kuI-VJP kanye nehlobene nayoimishini.
2. Ukupholisa i-VJP ngaphambi kokusetshenziswa
Njengoba i-VJP engasetshenziswanga isezingeni lokushisa elizungezile, ipayipi ligcwele umoya oqukethe umswakama. Ngakho-ke, inhloso yokupholisa ngaphambi kokupholisa iwukuthi: okokuqala, ukunciphisa kancane kancane izinga lokushisa le-VJP liye ezingeni lokushisa loketshezi oluyi-cryogenic, ukuze kugwenywe ukuthintana ngqo kwenani elikhulu loketshezi oluyi-cryogenic nepayipi lokushisa elijwayelekile, okukhiqiza inani elikhulu legesi elisheshayo, okuholela ekucindezelweni okusheshayo kwe-VJP, ngaleyo ndlela kubangele umonakalo ku-VJP kanye nemishini yoketshezi oluyi-terminal. Okwesibili, ukususa kancane kancane umoya ngaphakathi kwe-VJP nokugwema inani elikhulu loketshezi oluyi-cryogenic oluthintana ngqo nomoya, okuholela ekuqandeni nasekuvalekeni ngaphakathi kwe-VJP.
Ngaphambi kokusetshenziswa kabusha kwepayipi le-vacuum adiabatic ngemuva kokusetshenziswa kokuqala noma ukumisa ukukhiqizwa, kufanele kupholiswe ngaphambi kwesikhathi ukuze ipayipi le-vacuum adiabatic lisebenze ngokujwayelekile kuphela ngemva kokufika esimweni sokusebenza.
3. IIndlela Yokupholisa Ngaphambi Kokubandakwe-VJP
Okokuqala, hlola ukuthi i-valves, igeyiji yokucindezelaskanye ne-valve yokuphephanjll.ohlelweni lwe-VJP zisesimweni esijwayelekile esihambisanayo. Ngemva kwalokhu okungenhlaishekesekuqediwe, vula kancane kancanei-valve yokungena yesistimu ye-VJPbese uphefumula/gasifyuketshezi olugeleza kancane emoyeni opholile ngaphambi kokusebenzisa-pholisaI-VJPngobamayelanaImizuzu engama-30. Ingcindezi kuI-VJPkushintshashintsha kakhulungalesi sikhathi.Lapho ingcindezi ku-I-VJPuma iqina, umthamo wokumunca ungandiswa kancane kancane kuze kube yilapho uhlangabezana nezidingo.(Qaphela: ngesikhathi senqubo yangaphambi kokupholisa, uma ingcindeziI-VJPiphakeme kunengcindezi yomklamo ehambisanayo,kumele kube khona ngokusheshakumisiweukufaka i-infusion ohlelweni lwe-VJP.Mesikhathini esithile,vula ngokupheleleumoya ovulekileivalvusemgqeni ukuze kukhululwe ingcindezi.)
4. Sindlu encane phansiI-VJP
Uma umisa ukumnika, akuvunyelwe ngokuphelele ukuvala ama-valve womabili amaphethelo ohlelo lwe-VJP ngasikhathi sinye, ukuze kwakheke isimo esivaliwe kuI-VJPuhlelo, okuholela ekucindezelweni ngokweqile koketshezi olusele ku-VJPngenxa yokushintsha kwegesi.
5. Izikhathi ezithileDishaja yeCi-ryogenicLama-iquid (Li-iquidOi-oxygen kuphela)
Ngoba ama-hydrocarbon kanye nezinsalela zikhonaI-VJP yeumoya-mpilo owuketshezi, lezi zinto zizobekwa epayipini langaphakathi isikhathi eside uma zithuthwa nge-I-VJP.Uma ama-hydrocarbon esebekwe epayipini ngobuningi obukhulu futhi isikhathi eside, njengoba isimo sezulu sishisa nomaukukhiqizwa kweumoya-mpilo owuketshezi uyaphelai-ped, ukugcwala kwama-hydrocarbon ku-I-VJPkuyanda, futhi ukusabela nge-oxygen esele kungabangelaanqhumai-sion.
6.UkuphephaDisenzokwe-VJP
Kuyo yonke i-I-VJPuhlelo kufanele lusethelwe uhlelo lokukhipha ugesi ngokuphepha (kufaka phakathi i-valve yokusiza kanye ne-vent valve), Lapho ingcindezi ye-VJP ifinyelela ingcindezi yokuvula yama-valve okuphepha ezovula ngokuzenzakalelayo futhi ikhulule ingcindezi ngesikhathi. Ngesikhathi esifanayo,umoya ovulekileAmavalvu angavulwa ngesandla ukuze kukhishwe ingcindezi ukuqinisekisa ukuphepha kohlelo lonke lwe-VJP.
