Kugeza ubu, korojeni ya progaramu ya siyariyeri isaba gufunga inzira ebyiri zifunga cyane cyane ubwoko bubiri bwimibumbe, aribwo umubumbe wisi hamwe numupira wimipira uhamye / hejuru ushyizwe hejuru yumupira.Ariko, hamwe niterambere ryiterambere ryibice bibiri bya kirogenike yumupira, abashushanya sisitemu babonye uburyo bushimishije kuruta imipira gakondo-imipira ireremba.Ifite umuvuduko mwinshi, nta mbogamizi ku cyerekezo gitemba no kwerekana icyerekezo cyo hagati, kandi irashobora gukora neza mubihe bya kirogenike.Kandi ubunini ni buto, uburemere bworoshye, kandi imiterere iroroshye.
Ikoreshwa rya Cryogenic risaba indangagaciro zirimo kwinjiza / gusohoka mu bigega byo kubikamo kuzuza no gusohora, kotsa igitutu imiyoboro ifunze ubusa, gazi na lisukiya, imiyoboro myinshi igizwe na sisitemu zitandukanye muri sitasiyo ya LNG, sisitemu zo kohereza, hamwe na tanker, sisitemu yo gukwirakwiza, kuvoma sitasiyo na LNG yuzuza lisansi, hamwe na gaze ya gaze isanzwe (GVUs) ijyanye na moteri ya lisansi ebyiri kumato.
Mubisobanuro byavuzwe haruguru, ibyerekezo-bibiri byo gufunga ibyuma bikoreshwa mugucunga no kuzimya amazi yo hagati.Ugereranije nubundi bwoko nkaimipira, bafite ibibazo byinshi:
Coefficient (Cv) iri hasi-ibi bizagira ingaruka kumahitamo yingero zose zingirakamaro kandi bizahinduka icyuho kibuza ubushobozi bwa sisitemu.
· Ukeneye gushiraho imirongo ikora kugirango ikore imirimo yo gufunga no kugenzura-ugereranije nu rukiramende ruzenguruka rukoreshwa mu kugenzura no gukoresha imipira yumupira hamwe nizindi mpande enye zingana, ubu bwoko bwibikoresho bufite imiterere igoye kandi ihenze.Igiciro nuburyo bugoye bwibikoresho byuzuye bya valve nibikoresho bikora biragaragara cyane.
· Niba kuzimya valve ikoreshwa kugirango umenye ibikorwa byihutirwa bisabwa na sisitemu nyinshi za LNG, ibintu bigoye bizaba birenze.
Kubikoresho bito bya LNG (SSLNG), ibibazo byavuzwe haruguru bizarushaho kugaragara, kubera ko sisitemu zigomba kuba nto, zikoresha amafaranga menshi, kandi zikagira ubushobozi bunini bwo gutembera kugirango zigabanye imizigo yo gupakurura no gupakurura.
Coefficient ya flux yumupira iruta iy'isi ya globe ingana.Muyandi magambo, ni ntoya mubunini bitagize ingaruka ku kigero cyo gutemba.Ibi bivuze ko ingano, uburemere nigiciro cya sisitemu yose yo kuvoma ndetse na sisitemu yose yagabanutse cyane.Muri icyo gihe, irashobora kongera cyane inyungu ku ishoramari (ROI) rya sisitemu ifitanye isano.
Byumvikane ko, korojeni isanzwe ireremba umupira ninzira imwe, idakwiranye na ssenariyo yavuzwe haruguru isaba gufunga inzira ebyiri.
Inzira imwe Vs Inzira ebyiri
Nkuko bigaragara ku gishushanyo cya 1, umupira usanzwe ureremba hejuru yimiterere ya kirogenike ufite umwobo wo kugabanya umuvuduko kuruhande rwo hejuru rwumupira wa valve kugirango wirinde umuvuduko ukwirakwira no kuzamuka mugihe uburyo bwo guhindura icyiciro.Iyo valve iri mumwanya ufunze, gaze ya gazi isanzwe yomekwe mumyanya yumubiri wa valve izatangira guhumuka no kwaguka, kandi ingano irashobora kugera ku nshuro 600 ingano yumwimerere nyuma yo kwagurwa byuzuye, bikaba bishobora gutuma valve iturika. .Mu rwego rwo gukumira iki kibazo, imipira myinshi isanzwe ireremba imipira yakoresheje uburyo bwo gufungura igitutu cyo hejuru.Kubera iyo mpamvu, imipira gakondo ntishobora gukoreshwa mubihe bisaba gufunga inzira ebyiri.
Kandi iyi niyo stade aho inzira-ebyiri za cryogenic float ball valve ishobora kwerekana impano zayo.Itandukaniro riri hagati yiyi valve nibisanzwe inzira imwe ya cryogenic valve ni:
· Nta gufungura kumupira wa valve kugirango ugabanye umuvuduko
· Irashobora gufunga amazi mu byerekezo byombi
· Nta gufungura kumupira wa valve kugirango ugabanye umuvuduko
· Irashobora gufunga amazi mu byerekezo byombi
Muburyo bubiri bwa kirogenike ireremba umupira, icyicaro cyinzira-ebyiri zipakiye intebe isimbuza uburyo bwo gufungura umuvuduko wo hejuru.Intebe yuzuye yuzuye isoko irashobora kurekura umuvuduko ukabije uterwa na gaze ya gazi isanzwe yometse mu cyuho cyumubiri wa valve, bityo ikabuza valve guturika, nkuko bigaragara ku gishushanyo cya 2.
Mubyongeyeho, intebe yuzuye yuzuye ya valve ifasha kugumisha valve kumurongo wo hasi no kugera kubikorwa byoroshye mubihe bya cryogenic.
Inzira ebyiri zo mu bwoko bwa cryogenic zireremba umupira wuzuye zifite icyiciro cya kabiri cya grafite yo gufunga impeta, kugirango valve ifite umurimo wo kwirinda umuriro.Keretse niba impanuka ikomeye itera polymer ibice bya valve gutwika, kashe ya kabiri ntizigera ihura nuburyo.Mugihe habaye impanuka, kashe yo murwego rwa kabiri izagera kumurimo wo kurinda umutekano wumuriro.
Ibyiza byinzira ebyiri
Ugereranije n’ibibumbe byisi, byashyizwe hejuru kandi byashyizwe hejuru hejuru yumupira wumupira, inzira-ebyiri zo mu bwoko bwa cryogenic float ball valve ifite ibyiza byose byumuvuduko mwinshi wa coefficient ball ball, kandi ntakabuza kumazi no kwerekana icyerekezo.Irashobora gukoreshwa neza mumiterere ya cryogenic;ingano ni ntoya kandi imiterere iroroshye.Guhuza ibikorwa nabyo biroroshye byoroshye (kuzenguruka iburyo-buringaniye) na miniaturize.Izi nyungu zisobanura ko sisitemu yose ari nto, yoroshye, kandi ihendutse cyane.
Ugereranije n’ibibumbe byisi, byashyizwe hejuru kandi byashyizwe hejuru hejuru yumupira wumupira, inzira-ebyiri zo mu bwoko bwa cryogenic float ball valve ifite ibyiza byose byumuvuduko mwinshi wa coefficient ball ball, kandi ntakabuza kumazi no kwerekana icyerekezo.Irashobora gukoreshwa neza mumiterere ya cryogenic;ingano ni ntoya kandi imiterere iroroshye.Guhuza ibikorwa nabyo biroroshye byoroshye (kuzenguruka iburyo-buringaniye) na miniaturize.Izi nyungu zisobanura ko sisitemu yose ari nto, yoroshye, kandi ihendutse cyane.
Imbonerahamwe 1 igereranya inzira-ebyiri za kirogenike zireremba umupira wumupira hamwe nindi mibumbe ifite imirimo isa uhereye kubitekerezo byo kubungabunga, ingano, uburemere, urwego rwa torque, kugenzura ingorane, hamwe nigiciro rusange, kandi muri make yerekana ibyiza byayo nibibi.
Niba ikigo gito cya LNG cyishe amasezerano kandi kigafata inzira ebyiri zo mu bwoko bwa cryogenic ball ball, irashobora gutanga umukino wuzuye kubyiza bidasanzwe byumupira wumupira, ni ukuvuga diameter yuzuye, umuvuduko mwinshi hamwe nigipimo kinini cyo gusohora imiyoboro.Ugereranije, irashobora gushyigikira imiyoboro ntoya mugihe ikomeza umuvuduko umwe, bityo irashobora kugabanya ubwinshi, uburemere, hamwe nuburemere bwa sisitemu, kandi irashobora no kugabanya ibiciro bya sisitemu yo kuvoma.
Ingingo ibanza yerekanye ibyiza byo gukoreshwa nka valve ifunga.Niba ikoreshwa nkigenzura rya valve, ibyiza bizagaragara cyane.Niba iburyo-buringaniye buzunguruka umupira wifashishijwe, ubunini bwibikoresho bya valve byikora bizagabanuka cyane, bityo byahindutse ikintu kidahinduka kuri sisitemu ya cryogenic.
Ibyingenzi byingenzi mubikoresho byavuzwe haruguru byavuzwe haruguru ni ibintu byoroshye kandi bifatika byuburyo bubiri bwa cryogenic float ball valve, hamwe nu rukiramende ruzunguruka rufite imiterere yoroshye kandi ikora neza.
Muri make, inzira-ebyiri za kirogenike zireremba umupira wa valve ufite akamaro keza "subversive" kuri sisitemu ya imiyoboro ya kirogenike.Mubikoresho bito bya LNG, irashobora gutanga umukino wuzuye kubyiza byayo.
Mu myaka mike ishize, iki gicuruzwa gishya cyagenzuwe mubikorwa bifatika, byerekana ko bifite akamaro kanini kubiciro byumushinga ndetse nigihe kirekire cyizewe cya sisitemu.
