IVACUUM BAYONETUQHAGAMSHELOTYPE NGEFLANGES KUNYE NEBHUTI
Imiqathango yoFakelo
I-VJP(umbhobho wevacuum ofakwe ibhatyi)kufuneka ibekwe kwindawo eyomileyo ngaphandle komoya phambi kokufakwa.Ingaphandleukupakishwaumaleko we-VJP awukwazibe vulaed, ukuthintela ityhubhu kwimizimba yangaphandle (isanti, izinto ezincinci, njl.). Kwimvula okanye ixesha elideimanziimozulu, kufuneka kwakhona ingqalelo ekhethekileyo ngaphakathi kumbhobho manzi.
Akuvumelekanga ukusebenzisa i-VJP ngokuthe ngqo njenge-electrode ye-welding, ukubetha arcokanye ukuwelda kwiVJP.
I-VJPukupakishwaumaleko awukwazi ukususwa de kube kufakwe umbhobho ukukhusela ukuchithwa kwe-welding kwezinye izikhundla.
Ngexesha lenkqubo yokufakela yonke, i-VJP kufuneka iphathwe ngononophelo. Khusela zombini izipheloof VJP, musa ukusebenzisa ivacuumidibeneyo kwi-VJP (umzobo 1 kunye ne-3) njengendawo yokunyanzeliswa kokuthintela ukuvuza kwe-vacuum.
Xa ufaka, nikela ingqalelo ekuthembekeni kokuphakanyiswa, musa ukuwa kunye nokulimala okanye ukulimala.
Amanyathelo oFakelo lweVJP
1. Khangelaiumzobos, nokuba ubungakanani kunye nobukhulukwemibhobhokwimizobo ziyafanangeiimibhobho yasendle. Bphambi kokufaka, fumanangaphandleVJP nganye ngokomzobo kunyeinani. Umzekelo:HL2018GLN-59-02-01, oku kuthetha ukuba ikhowudi yeprojekthi yi-59, i-nitrogen medium liquid, umbhobhoHayi.01 yomgcaHayi.02. I-nameplate yentsimbi enale ntoinaniiqhotyoshelwe kwi-VJP kwindawo (umzobo 1), kwaye i-nameplate ye-corrosion yombane iqhotyoshelwekufutshane nendawo yokufunxaiVJP(umzobo 2).
Qaphela: iubungakananikunye neNo.yemibhobho kumzobo kufuneka ifane neubungakananikwayeHayi.yeVJPsemhlabeni. Ukuba kukho ukungangqinelani ekuhlolweni, qiniseka ukuba uqhagamshelane nabasebenzi bethu kwindawo.
2. Emva kokujonga ubuninzi beVJP kunyeHayi.,ngokwemizobo, shukumaiVJPskwisibiyeli esihambelanayos/inkxasookanye indawoVJPsemhlabeni ecaleni kwesibiyeli esihambelanayos/inkxaso.
3. Ngaphambi kokuba iiflange zidityaniswe, jonga kuqala ukuba ikhonkco lokutywina kunye neyunithi yokutywina ebandayo ifakwe ngokufanelekileyo.
4. Coca amalungu eibhinqa nendodaulwandisoumbhobho, itywinaimisesanekunye neyunithi yetywina ebandayo ene-oyile-free kunye ne-reagent engenamanzi.
5. Faka umbhobho wokwandiswa kwenkunzi nemazi ngokuthe tye nangokucothayo. Emva koko tsala iiflange ezimbini kunye kwaye ucinezele, kwaye ufake zonke iibholiti kwiiflange (ungaziqinisi ngoku).
6. Emva kokuqinisekisa indawo echanekileyo yeeflange ezimbini, qinisa i-bolts step by step. Qinisekisa ukuba i-flange igcinwe kwinqanaba ngexesha lofakelo
7. Khangela ukuba ukuqiniswa kweflange kufanelekile.
8. Iikhefu lenkxaso ezimbini yi-3m, i-PTFE ipleyiti kufuneka ifakwe phakathi kwendawo yokuxhasa kunyengaphandleumbhobho.
Iinkcukacha zokuSebenza noLondolozo
1. Abaqhubi kufuneka baqhelene neumsebenziukuhambas phakathi kwezixhobo kwinkqubo. Kufuneka kwaziwe ukuba ioksijini yolwelo, initrogen engamanzi kunye ne-argon yolwelo lulwelo lwe-cryogenic. Xa ubushushu be-ambient buphezulu kunendawo yokubilisa, baya kuba ngokwendalogasifykunye noxinzelelo, okukhokelela ekunyukeni kancinci koxinzelelo kwiVJP kunye nezinto ezinxulumene nazoizixhobo.
2. Ukupholisa kwangaphambili kweVJP phambi kokusetyenziswa
Ekubeni i-VJP engasetyenziswanga ikwiqondo lokushisa eliphantsi, umbhobho uzaliswe ngumoya oqulethe umswakama. Ngoko ke, injongo yokupholisa kwangaphambili kukuba: okokuqala, ukunciphisa ngokuthe ngcembe ubushushu be-VJP ukuya kwiqondo lokushisa lolwelo lwe-cryogenic, ukuze ugweme uqhagamshelwano oluthe ngqo lwesixa esikhulu solwelo lwe-cryogenic kunye nombhobho wobushushu oqhelekileyo, uvelisa ngokukhawuleza. kunye nesixa esikhulu se-gasification, okubangele uxinzeleko olukhawulezayo lwe-VJP, ngaloo ndlela kubangele umonakalo kwi-VJP kunye nezixhobo ze-terminal liquid. Okwesibini, kukususa umoya ngokuthe ngcembe ngaphakathi kweVJP kunye nokuphepha inani elikhulu lolwelo lwe-cryogenic oludibana ngqo nomoya, okukhokelela ekukhenkceni nasekuvalelekeni ngaphakathi kweVJP.
Ngaphambi kokusetyenziswa kwakhona kombhobho we-adiabatic we-vacuum emva kokusetyenziswa kokuqala okanye ukuyeka ukuveliswa, ukupholisa kwangaphambili kuya kwenziwa ukuze umbhobho we-adiabatic we-vacuum usebenze ngokuqhelekileyo emva kokuba ufikelele kwindawo yokusebenza.
3. IIndlela yokupholisa kwangaphambiliyeVJP
Okokuqala, khangela ukuba ivalves, ekhupha ifutheskunye nevalve yokhuselekos njl.kwinkqubo yeVJP zikwimeko eqhelekileyo ehambelanayo. Emva koku kungasentlakhangelaigqityiwe, vula kancinci iivalve yokungena yeVJP inkqubokwaye umphunga/gasifyulwelo oluhamba kancinci emoyeni olupholileyo ukuya ngaphambili-pholisa iVJPngenxamalungaImizuzu engama-30. Uxinzelelo kwiVJPiyatshintsha kakhulungeli xesha.Xa uxinzelelo kwiVJPuzinza, umthamo wokugalela unokwandiswa ngokuthe chu de ufezekise iimfuno.(Qaphela: ngexesha lenkqubo yokupholisa kwangaphambili, ukuba uxinzelelo kwiVJPiphezulu kunoxinzelelo loyilo oluhambelanayo,kufuneka kube ngoko nangokowayekaukufakwa kwinkqubo yeVJP.Mngeli xesha,vula ngokupheleleyo iikrobaivalveskumgca wokukhulula uxinzelelo.)
4. Shlala phantsiVJP
Xa uyeka ukumiliselwa, akuvumelekanga ngokungqongqo ukuvala iivalvu zombini iziphelo zenkqubo yeVJP ngaxeshanye, ukuze wenze imo evaliweyo kwindawo.VJPinkqubo, ekhokelela kuxinzelelo olugqithisileyo lolwelo olushiyekileyo kwi-VJPngenxa yegesi.
5. Ngamaxesha athileDukukhutshwa kweCryogenicLiiquids (LiquidOi-oxygen Kuphela)
Ngenxa yokuba ii-hydrocarbons kunye neentsalela zikhonaVJP yeioksijini engamanzi, ezi zinto ziya kufakwa kumbhobho wangaphakathi ixesha elide xa zithuthwa ngeVJP.Nje ukuba ii-hydrocarbons zifakwe kwityhubhu ngobuninzi kwaye ixesha elide, njengoko imozulu ishushu okanyeimveliso yeioksijini engamanzi yistoip, Uxinzelelo lweehydrocarbons kwiVJPukwanda, kwaye ukusabela ngeoksijini eseleyo kunokubangelaanqhumaumbono.
6.UkhuselekoDeviceyeVJP
Kwindawo nganyeVJPinkqubo kufuneka imiselwe inkqubo yokukhutshwa kokhuseleko (kubandakanya i-valve yokunceda kunye ne-valve ye-vent), Xa uxinzelelo lwe-VJP lufikelela kuxinzelelo lokuvula lwee-valve ezikhuselekileyo eziza kuvula ngokuzenzekelayo kwaye zikhulule uxinzelelo ngexesha. Kwangaxeshanye, iikrobaiivalve nazo zinokuvulwa ngesandla ukukhulula uxinzelelo lokuqinisekisa ukhuseleko lwenkqubo yonke yeVJP.
Ukungasebenzi kakuhle kunye nokuLahla
