KUBURYO BWA VACUUM JACKETED PIPING SYSTEM
VACUUM BAYONETIHURIROUBWOKO HAMWE N'INDIMI NA BOLTS
Kwirinda
VJP(vacuum jacketed piping)bigomba gushyirwa ahantu humye nta muyaga mbere yo kwishyiriraho.Uwitekahanzegupakiraurwego rwa VJP ntirushoborabe funguraed, kugirango wirinde umuyoboro mumibiri yamahanga (umucanga, ibinyabuzima bito, nibindi).Mu mvura cyangwa igihe kirekireitoseikirere, nacyo gikeneye kwitondera byumwihariko imbere yumuyoboro utagira amazi.
Birabujijwe gukoresha VJP mu buryo butaziguye nka welding electrode, gukubita arccyangwa gusudira kuri VJP.
VJPgupakiralayer ntishobora gukurwaho kugeza umuyoboro ushyizweho kugirango wirinde gusenyuka gusudira muyindi myanya.
Mugihe cyose cyo kwishyiriraho, VJP igomba gukemurwa neza.Rinda impande zombiya VJP, ntukoreshe iicyuhogufatanya kuri VJP (ishusho 1 na 3) nkingingo yingufu zo gukumira icyuho.
Mugihe ushyiraho, witondere kwizerwa ryo kuzamura, ntugwe kandi wangiritse cyangwa igikomere.
Intambwe zo Kwishyiriraho VJP
1. Rebaigushushanyas, ingano n'ubuniniy'imiyoboroku bishushanyo ni kimwehamwe naiimiyoboro yo mu murima.B.mbere yo kwishyiriraho, shakishahanzeburi VJP ukurikije igishushanyo nanimero.Urugero:HL2018GLN-59-02-01, bivuze ko code yumushinga ari 59, amazi ya azote yuzuye, umuyoboroOya.01 y'umurongoOya.02. Icyapa cyanditseho icyumanimeroiherekejwe na VJP kurubuga (ishusho 1), kandi icyapa cyerekana amashanyarazihafi ya vacuum ihuriweho kuriiVJP(ishusho 2).
Icyitonderwa :.inganona Oya.y'imiyoboro mu gushushanya igomba kuba imwe nainganonaOya.ByaVJPskurubuga.Niba hari ibitagenda neza mugenzura, menya neza kuvugana nabakozi bacu kurubuga.
2. Nyuma yo kugenzura ingano ya VJP naOya.,ukurikije ibishushanyo, kwimukaVJPsku murongo uhuyes / inkungacyangwa ahantuVJPshasi kuruhande rwinyuguti zihuyes / inkunga.
3. Mbere yuko flanges ihuzwa, banza urebe niba impeta ya kashe hamwe nimbeho ikonje yashyizweho neza
4. Sukura ingingo zaigitsina gore & gabokwagukaumuyoboro, kasheimpetahamwe na kashe ikonje hamwe na reagent idafite amavuta.
5. Shyiramo umuyoboro mugari wumugabo numugore utambitse kandi buhoro.Noneho kurura flanges ebyiri hamwe hanyuma ukande, hanyuma ushyireho Bolt zose kuri flanges (ntukizirike nonaha).
6. Nyuma yo kwemeza neza imyanya ibiri ya flanges, komeza Bolts intambwe ku yindi.Menya neza ko flange ibitswe murwego rwo kwishyiriraho
7. Reba niba gufunga flange byujuje ibisabwa.
8. Theintera yinkunga ebyiri ni 3m, isahani ya PTFE igomba gushyirwaho hagati yingoboka nahanzeumuyoboro.
Ibisobanuro birambuye kubikorwa no kubungabunga
1. Abakoresha bagomba kuba bamenyereye iakazigutembas hagati y'ibikoresho muri sisitemu. Bikwiye kumenyekana ko ogisijeni y'amazi, azote yuzuye na argon y'amazi ari cryogenic fluid.Iyo ubushyuhe bwibidukikije burenze aho butetse, bizaba bisanzwegazihamwe nigitutu, bivamo kwiyongera buhoro buhoro umuvuduko muriVJP hamwe nayoibikoresho.
2. Precooling ya VJP mbere yo Gukoresha
Kubera ko VJP idakoreshwa iri ku bushyuhe bw’ibidukikije, umuyoboro wuzuye umwuka urimo ubushuhe.Kubwibyo, intego yo kubanziriza gukonjesha ni: icya mbere, kugabanya buhoro buhoro ubushyuhe bwa VJP kugeza ku bushyuhe bw’amazi ya kirogenike, kugira ngo wirinde guhura bitaziguye n’amazi menshi ya kirogenike hamwe n’umuyoboro usanzwe w’ubushyuhe, bikabyara vuba na gazi nyinshi, bikaviramo umuvuduko mwinshi wa VJP, bityo bikangiza ibyangiritse bya VJP nibikoresho byamazi.Icya kabiri, ni ugukuraho buhoro buhoro umwuka uri muri VJP no kwirinda umubare munini wamazi ya kirogenike ahura nikirere, bikaviramo gukonja no gufunga imbere muri VJP.
Mbere yo kongera gukoresha umuyoboro wa vacuum adiabatic nyuma yo gukoreshwa bwa mbere cyangwa guhagarika umusaruro, precooling igomba gukorwa kugirango umuyoboro wa vacuum adiabatic ushobora gukora bisanzwe nyuma yo kugera kuri leta ikora.
3.UwitekaUburyo bwo kubanzirizaya VJP
Banza, reba niba valvesigipimo cy'umuvudukosna valve y'umutekanos n'ibindimuri sisitemu ya VJP iri muburyo busanzwe.Nyuma yavuzwe harugurukugenzuraByarangiye, fungura buhoro buhoroinlet valve ya sisitemu ya VJPno guhumeka/ gaziamazi make-mumazi akonje kugirango abanze-gukonjaVJPKurihafiIminota 30.Umuvuduko muriVJPihindagurika cyanemuri iki gihe.Iyo igitutu muriVJPihinduka ituze, ingano ya infusion irashobora kwiyongera buhoro buhoro kugeza yujuje ibisabwa.(Icyitonderwa: mugihe cyo kubanziriza gukonjesha, niba igitutu muriVJPni hejuru kurenza igitutu gishushanyije,bigomba guhitayarahagazekwinjiza muri sisitemu ya VJP.Mburigihe,fungura rwoseumushingaindangaskumurongo wo kurekura igitutu.)
4.S.igituba HasiVJP
Iyo uhagaritse kwinjiza, birabujijwe rwose gufunga indangagaciro zimpande zombi za sisitemu ya VJP icyarimwe, kugirango dushyireho leta ifunze muriVJPsisitemu, bivamo gukabya gukabije kwamazi asigaye muri VJPkubera gaze.
5. IkiringoDischarge yaCryogenicLiquids (LiquidOxygen Gusa)
Kuberako hydrocarbone nibisigara bibahoVJP yaumwuka wa ogisijeni, ibyo bintu bizashyirwa mumuyoboro wimbere igihe kirekire iyo bitwarwa binyuze muriVJP.Iyo hydrocarbone imaze gushyirwa mu muyoboro mwinshi kandi mugihe kirekire, nkuko ikirere gishyuha cyangwaumusaruro waumwuka wa ogisijeni ni stopped, kwibumbira hamwe kwa hydrocarbone muriVJPyiyongera, kandi reaction hamwe na ogisijeni isigaye irashobora guteraangushakishasion.
6.UmutekanoDeviceya VJP
Muri buriVJPsisitemu igomba gushyirwaho sisitemu yo gusohora umutekano (harimo na valve yubutabazi na valve valve), Iyo umuvuduko wa VJP ugeze kumuvuduko wo gufungura indangagaciro z'umutekano zizahita zifungura kandi zirekure igitutu mugihe.Igihe kimwe ,.umushingavalve nayo irashobora gufungurwa nintoki kugirango irekure igitutu kugirango umutekano wa sisitemu yose ya VJP.
