EE NIDAAMKA JACAYLKA VACUUMKA AH
VACUUM BAYONETXIDHIIDHKAKU NOQO CALANKA IYO BOLLADA
Taxadirka Rakibaadda
VJP( tuubooyinka jaakad vacuum ah)waa in la dhigo meel qalalan oo aan dabayl lahayn ka hor inta aan la rakibin.Thedibaddabaakadlakabka VJP ma awoodobe furaned, si looga hortago in tuubada galaan jidhka shisheeye (cammuudda, noolaha yaryar, iwm.). Roobka ama muddada dheerqoyanCimilada, sidoo kale waxay u baahan tahay inaad fiiro gaar ah u yeelato gudaha dhuumaha biyaha celinaya.
Waa mamnuuc in si toos ah loo isticmaalo VJP sida korantada alxanka, ku dhufoama alxanka VJP.
VJPbaakadlakabka lama saari karo ilaa tuubada la rakibo si looga hortago burburka alxanka ee meelaha kale.
Inta lagu jiro habka rakibida oo dhan, VJP waa in si taxadar leh loo maareeyaa. Ilaali labada darafee VJP, ha isticmaalinfaaruqwadajirka VJP (jaantuska 1 iyo 3) oo ah barta xoogga si looga hortago daadinta faakuumka.
Markaad rakibayso, fiiro gaar ah u yeelo kalsoonida kor u qaadista, ha ku dhicin oo dhaawac ama dhaawac.
Tallaabooyinka Rakibaadda ee VJP
1. Hubiahsawirids, haddii ay tahay tirada iyo cabbirkaee tuubooyinkasawirada waa isku midlehahtuubooyinka garoonka. Before rakibaadda, helibaxayVJP kasta si waafaqsan sawirka iyolambarka. Tusaale:HL2018GLN-59-02-01, taas oo macnaheedu yahay koodhka mashruuca waa 59, dhexdhexaad ah nitrogen dareere, tuuboMaya01 ee lineMaya02. Bir magac leh oo tan lehlambarkawaxay ku dheggan tahay VJP goobta (jaantuska 1), iyo magaca daxalka korantada ayaa ku lifaaqanmeel u dhow kala-goyska vacuum onahVJP(Jaantuska 2).
Fiiro gaar ah: thetiroiyo Maya.Tuubooyinka sawirku waa inay la mid noqdaan kuwatiroiyoMayaeeVJP-yadagoobta. Haddii uu jiro khilaaf xagga hubinta ah, hubi inaad la xiriirto shaqaalahayaga goobta.
2. Ka dib markii la hubiyo tirada VJP iyoMaya,sida ku cad sawirada dhaqaaqidVJPson garabka u dhigmas/taageeraaama meelVJP-yadadhulka ku xiga barkin u dhigmas/taageeraa
3. Ka hor inta aan cidhifyada la xidhin, marka hore hubi in giraanta shaabadda iyo qaybta shaabadda qabow si habboon loo rakibay
4. Nadiifi kala-goysyadadheddig & labkordhintuubo, shaabadfaraantiiyo unug shaabad qabooji leh oo aan saliid iyo biyo lahayn.
5. Geli dhuumaha fidinta lab iyo dhedig si siman oo tartiib ah. Ka dib labada garab isku soo jiid oo riix, oo ku dheji dhammaan boolasha garbaha (ha adkayn hadda).
6. Ka dib markaad hubiso booska saxda ah ee labada garab, adkee boolalka talaabo talaabo. Hubi in flangegu uu ahaado mid siman inta lagu jiro rakibidda
7. Hubi in adkaynta garabku ay u qalanto iyo in kale.
8. Theinta u dhaxaysa labada taageero waa 3m, saxan PTFE waa in lagu rakibaa inta u dhaxaysa barta taageerada iyodibaddatuubo.
Faahfaahinta Hawlaha & Dayactirka
1. Hawl-wadeenadu waa inay yaqaaniinshaqadasocodkas inta u dhaxaysa qalabka nidaamka. Waa in la ogaadaa in ogsijiin dareeraha ah, nitrogen dareere ah iyo argon dareere ah ay yihiin dareeraha cryogenic. Marka heerkulka deegaanku ka sarreeyo barta karkarinta, waxay noqon doonaan si dabiici ahgaaskaiyo cadaadis, taasoo keentay in si tartiib tartiib ah u kordho cadaadiska gudahaVJP iyo kuwa la xiriiraqalabka.
2. Qaboojinta kahor isticmaalka VJP ka hor
Maadaama VJP-ga aan la isticmaalin uu ku sugan yahay heerkulka deegaanka, tuubada waxaa ka buuxa hawo ka kooban qoyaan. Sidaa darteed, ujeedada hore ee qaboojinta waa: marka hore, si tartiib tartiib ah loo yareeyo heerkulka VJP heerkulka dareeraha cryogenic, si looga fogaado xidhiidhka tooska ah ee qadar badan oo dareere ah oo leh tuubada heerkulka caadiga ah, soo saarista degdeg ah. iyo qadar aad u badan oo gaas ah, taasoo keentay cadaadis degdeg ah oo VJP ah, sidaas darteed waxyeelo u geysata VJP iyo qalabka dareeraha ee terminal. Midda labaad, waa in si tartiib tartiib ah hawada looga saaro gudaha VJP iyo in laga fogaado tiro badan oo dareere cryogenic ah oo toos ah hawada, taasoo keenta baraf iyo xannibaad gudaha VJP.
Kahor inta aan dib loo isticmaalin tuubada adiabatic vacuum ka dib isticmaalka ugu horeeya ama joojinta wax soo saarka, precooling waa in la sameeyaa si tuubada adiabatic vacuum ay si caadi ah u shaqeyso kaliya ka dib marka ay gaarto gobolka shaqada.
3. TheHabka qaboojinta kahoree VJP
Marka hore, hubi in valve-ka iyo in kales, cadaadiska cadaadiskasiyo waalka badbaadadas iwm.nidaamka VJP waxay ku jiraan xaalad caadi ah oo u dhiganta. Kor ka dibhubiwaa la dhammeeyaa, si tartiib ah u furwaalka gelitaanka ee nidaamka VJPoo uumi/gaasifydareeraha qulqulaya hoose ee hawo qabow si uu horay u sii galo-qaboojiVJPwaayoku saabsan30 daqiiqo Cadaadiska ku jiraVJPsi weyn isu bedbeddeshaawaqtigan.Marka cadaadiska ku jiraVJPwuxuu noqdaa mid deggan, mugga faleebo ayaa si tartiib tartiib ah loo kordhin karaa ilaa uu ka soo baxo shuruudaha.(Fiiro gaar ah: inta lagu jiro habka qaboojinta ka hor, haddii cadaadiska ku jiraVJPwuu ka sarreeyaa cadaadiska naqshadaynta u dhigma,waa inay isla markiiba noqotaajoogsadayin lagu shubo nidaamka VJP.Mintaa ka dib,si buuxda u furhawowaalkaskhadka si loo sii daayo cadaadiska.)
4. Sbuul Down theVJP
Marka la joojiyo faleebada, waxaa si adag loo mamnuucay in la xidho furayaasha labada daraf ee nidaamka VJP isku mar, si ay u sameeyaan dawlad xiranVJPnidaamka, taasoo keentay cadaadis xad-dhaaf ah ee dareeraha haraaga ah ee VJPgaaska awgeed.
5. Mar marDeedaysane ahCryogenicLiquids (LiquidOxygen kaliya)
Sababtoo ah hydrocarbons iyo hadhaaga ayaa ku jiraVJP eeOgsajiinta dareeraha ah, walxahan waxaa lagu kaydin doonaa dhuumaha gudaha muddo dheer marka la dhex qaadoVJP.Marka hydrocarbons lagu shubo tuubada tiro badan iyo waqti dheer, marka cimiladu kululaato amawax soo saarkadareeraha ogsijiinta waa stoku dhuftay, fiirsashada hydrocarbons ee ku jiraVJPway kordhisaa, falcelinta ogsijiinta hadhayna waxay keeni kartaaanqarxision.
6.BadbaadadaDxumaanee VJP
Mid kasta oo ka mid ahVJPNidaamka waa in la dejiyaa nidaamka dareeraha badbaadada (oo ay ku jiraan valve gargaarka iyo valve hawo-mareenka), Marka cadaadiska VJP uu gaaro cadaadiska furitaanka ee valves badbaadada kaas oo si toos ah u furi doona oo sii deyn doona cadaadiska wakhtiga. Isla markaana,hawovalves sidoo kale gacanta ayaa lagu furi karaa si loo sii daayo cadaadiska si loo hubiyo badbaadada nidaamka VJP oo dhan.
