Yenkqubo yokuthintela i-vackeum
Vacuum bayonetUqhagamsheloChwetheza ngeflethi kunye nee-bolts
Amanyathelo okhuseleko
I-vjp(Ukunyibilika kombhobho we-vacuum)kufuneka ibekwe kwindawo eyomileyo ngaphandle komoya ngaphambi kofakelo.Ingaphandleukupakishaungqimba lwe-vjp alunakhobe vulaed, ukuthintela ityhubhu ibe yimigudu yabantu (intlabathi, izinto ezincinci, njl. Njl.). Kwimvula okanye ixesha elideemanziImozulu, kufuneka inike ingqalelo ekhethekileyo ngaphakathi kwi-pipeline amanzi.
Akuvumelekanga ukusebenzisa i-VJP ngokuthe ngqo njengoko i-welting ye-welrode, thabatha i-arcokanye i-welding kwi-vjp.
I-vjpukupakishaUngqimba akanakususwa de kube kufakwe umbhobho ekuthintelwe ukunqanda ukuqhekezwa kwe-welding kwezinye izikhundla.
Ngexesha lenkqubo yonke yokufaka, i-VJP kufuneka ihlawulwe ngononophelo. Khusela zombini izipheloye-vjp, musa ukusebenzisa ivacuumUkudibana kwi-vjp (umzobo 1 kunye ne-3) njengendawo yokunyanzelwa ukuthintela ukuvuza kwe-vacuum.
Xa ufaka inkangeleko yokuthembeka kokuthengiswa, musa ukuwa kwaye wonakalise okanye wenzakala.
Amanyathelo ofake kwi-VJP
1. Jongaiumzobos, Nokuba linani kunye nobungakananiimibhobhokwimizobo ziyafanangeiImibhobho yasendle. Bokufakekayo, fumanangaphandleI-VJP nganye ngokomzobo kwayeinombolo. Umzekelo:HLNgo-2018I-gln-59-02-01, Oko kuthetha ukuba ikhowudi yeprojekthi yi-59, i-nitrogen ye-nitrogen ephakathi, umbhobhoHayi.I-01 yomgcaHayi.I-02. Imephu yentsimbi ngale ntoinomboloiqhotyoshelwe kwi-vjp kwindawo (umzobo 1), kunye nemephu yombane eqhotyoshelweyo iqhotyoshelwekufutshane ne-vacuum idibeneyoiVjp(Umzobo 2).
Qaphela: Iubungakananikwaye hayi.Imibhobho kumzobo kufuneka ifane neubungakananikwayeHayi.yeI-VJPSemhlabeni. Ukuba kukho nakuphi na ukungangqinelani ekuhlolweni, qiniseka ukuba nxibelelana nabasebenzi bethu kwindawo.
2. Emva kokujonga ubungakanani be-vjp kwayeHayi.,Ngokwemizobo, hambisai-vjpskwi-bracket ehambelanayos / inkxasookanye indawoI-VJPSemhlabeni ecaleni kwe-bracket ehambelanas / inkxaso.
I-3. Ngaphambi kokuba ifleves ixhunyiwe, qala ujonge ukuba ngaba i-teal i-rings kunye neyunithi yetywina ebandayo lifakwe ngokufanelekileyo
4. Hlambulula udibaniso lweibhinqa nendodaulwandisoumbhobho, tywinaamakhonkcokunye neyunithi yetywina elibandayo eline-ombolo yeoli kunye ne-free-free.
I-5. Faka i-thes kunye ne-pie yodondoloniso lwe-pie ngokuthe tyaba kwaye kancinci. Emva koko tsala i-flaxes ezimbini kunye kwaye cinezela, kwaye ufake zonke ii-bolts kwiflethi (ungazinzisi ngoku).
6. Emva kokuqinisekisa imeko echanekileyo ye-flaxes ezimbini, qinisa i-bolts inyathelo ngenyathelo. Qinisekisa ukuba i-flange igcinwe kwinqanaba ngexesha lokufakwa
7. Jonga ukuba i-flange iqinile ifanelekile.
8. IUkuphumla kwenkxaso emibini yi-3m, iplate ye-ptfe kufuneka ifakwe phakathi kwendawo yenkxaso kunyengaphandleumbhobho.
Iinkcukacha zokuSebenza kunye nokuLondolozwa
1. Abanini zithuthi kufuneka baqhelane nesebenzaukuhambas phakathi kwezixhobo kwinkqubo. Kufuneka yaziwe ukuba ioksijini ye-atenigen, i-nitrogen yolwelo kunye ne-argon ye-argon ngamathambisi. Xa iqondo lobushushu elaneleyo liphezulu kunendawo yokubila, baya kuba ngokwemvelohlukanisakwaye ucinezelwe, okukhokelela kunyuka ngokuthe ngcembe kwingcinezelo kwiI-VJP kwaye inxulumeneizixhobo.
I-2. Ukunyanzeliswa kwe-vjp ngaphambi kokusebenzisa
Kuba i-vjp engasetyenziswanga ikwiindlela zobushushu obuthambileyo, umbhobho uzaliswe ngumoya oqukethe umswakama. Ke ngoko, injongo yokupholisa kwangaphambili yile: Okokuqala, ukuthoba ngokuthe ngcembe i-vjp kulwelo lwe-crygenic kulwelo oluqhelekileyo lolwesi-crygenic kunye nombhobho wamaqondo obushushu, ukuvelisa ngokukhawuleza Kwaye isixa esikhulu sokunyanzeliswa, sikhokelela ekugxothweni ngokukhawuleza kwe-vjp, ngenxa yoko kubangela ukonakala kwi-vjp kunye nezixhobo zamanzi. Okwesibini, kuya kususa ngokuthe ngcembe umoya ngaphakathi kwi-vjp kwaye uphephe inani elikhulu lolwelo lwe-Crygenic lunxibelelwano ngqo nomoya, okukhokelela kwi-vjp.
Ngaphambi kokusetyenziswa kwakhona kombhobho we-adiabatic ye-adiabhotic emva kokusetyenziswa kokuqala okanye ukumisa, ukumiswa kwangaphambili kuya kwenziwa ukuze umbhobho we-adiabatic onokuthi asebenze kuphela emva kokuba ifikelela kwimeko yokusebenza.
3. IIndlela yokwenyaniye-vjp
Okokuqala, jonga ukuba ivalis, ekhupha ifutheskunye nevalve ekhuselekileyos njl.Kwinkqubo ye-vjp bakwimeko efanayo eqhelekileyo. Emva kokungentlajongaigqityiwe, vula kancinciI-Inlet yeValve yeNkqubo ye-VJPkwaye ivule/ xelai-rating drive ingene kwi-moya epholileyo ukuya ngaphambili-phola iVjpkubamalungaImizuzu engama-30. Uxinzelelo kwiVjptshintsha kakhulungeli xesha.Xa uxinzelelo kwiVjpIbambekile, ivolumu ye-infurion inokwandisa ngokuthe ngcembe de ihlangabezane neemfuno.(Qaphela: Ngexesha lenkqubo yokupholisa kwangaphambili, ukuba ingcinezelo kwiVjpiphakamile kunengcinezelo yoyilo ehambelanayo,kufuneka iboniswe kwangokoyemaukupheliswa kwenkqubo ye-vjp.MI-Eanwhile,vula ngokupheleleyo iventivalveskumgca wokukhupha uxinzelelo.)
4. SHlela phantsiVjp
Xa uyeka ukungcola, kuyathintelwa ukuba kuvalwe iivalves zomibini iziphelo zenkqubo ye-vjp ngexesha elinye, ukwenzela imeko evaliweyo kwiVjpInkqubo, ngenxa yokugqwesa ulwelo olugqithisileyo kwi-vjpngenxa yokuguqula.
5. NgamaxeshaDischar yeCryogenicLiquids (LiquidOI-xygen kuphela)
Kuba i-hydrocarbons kunye neentsalela zikhonaI-vjp yeioksijini yolwelo, Ezi zinto ziya kufakwa kumbhobho wangaphakathi ixesha elide xa zithuthwaI-VJP.Nje ukuba i-hydrocarbons ifakwe kwityhubhu kwityhubhu enkulu kunye nexesha elide, njengoko imozulu iphakama okanye iukuvelisaioksijini ye-axygen inyibilikaipeni, uxinzelelo lwe-hydrocarbons kwiVjpinyuka, kwaye impendulo esele ikwi-oxegen enokubangelaanqhubekaion.
6.UkhuselekoDi-eviceye-vjp
Kwinye yeVjpInkqubo kufuneka isethwe inkqubo yokukhupha i-rolve kunye nevalve yokunceda kunye ne-valve evelayo), xa uxinzelelo lwe-VJP lufikelela kwi-valves evulekileyo kwaye ikhuphe uxinzelelo ngexesha. Kwangelo xesha, iventIivavu zinokuvulwa kwakhona ukuba zikhuphe uxinzelelo lokuqinisekisa ukhuseleko lwenkqubo ye-VPP iphela.
Ukungasebenzi kakuhle kunye nokulahla
