Kukwaniritsa zofunika kwambiri makasitomala pa kuthamanga kwa madzi ndi kuthamanga kwa mpweya mu kapangidwe kaflange magetsi Kutentha machubu,kukhathamiritsa kokwanira kumafunika kuchokera kumitundu ingapo monga kusankha zinthu, kapangidwe kake, kupanga, ndi kutsimikizira magwiridwe antchito. Dongosolo lachindunji lili motere:
1,Kusankha kwazinthu: Sinthani mphamvu zopondereza ndi maziko osindikiza
1. Kusankhidwa kwa zipangizo zazikulu za chitoliro
Zida zamphamvu kwambiri komanso zolimbana ndi dzimbiri zimakondedwa pazovuta kwambiri zogwirira ntchito (kuthamanga kwamadzi≥10MPa kapena kuthamanga kwa mpweya≥6MPa), monga:
Chitsulo chosapanga dzimbiri 316L (chosamva kuwononga media wamba, mphamvu yopondereza≥520MPa);
Incoloy 800 (yosagwirizana ndi kutentha kwakukulu, kuthamanga kwambiri ndi okosijeni, yoyenera kutentha kwa nthunzi kutentha, mphamvu zokolola≥240MPa);
Titaniyamu alloy/Hastelloy alloy (pazinthu zowononga kwambiri komanso zopanikizika kwambiri monga madzi am'nyanja ndi ma acid-base solution).
Makulidwe a khoma la chitoliro amawerengedwa molingana ndi miyezo ya GB/T 151 Heat Exchanger kapena ASME BPVC VIII-1, kuwonetsetsa kuti makulidwe a khoma≥20% (monga kuwerengera khoma makulidwe + 0.5mm chitetezo chinthu pamene kuthamanga ntchito ndi 15MPa).
2. Flange ndi zisindikizo zofanana
Mtundu wa Flange: Pazochitika zopanikizika kwambiri, ma flanges a khosi (WNRF) kapena integral flanges (IF) amagwiritsidwa ntchito, ndipo malo osindikizira amasankhidwa ngati mortise ndi tenon (TG) kapena ring joint (RJ) kuti achepetse chiopsezo cha kusindikiza pamwamba.
Gasket yosindikiza: Sankhani gasket yokulungidwa yachitsulo (yokhala ndi mphete zamkati ndi zakunja) (kukana kukakamiza≤25MPa) kapena octagonal zitsulo mphete gasket (kuthamanga kwambiri ndi kutentha, kukana kuthamanga≥40MPa) molingana ndi mawonekedwe a sing'anga. The gasket zakuthupi n'zogwirizana ndi zinthu chitoliro (monga 316L gasket ndi 316L flange).
2,Mapangidwe Apangidwe: Kulimbikitsa Kupanikizika ndi Kudalirika
1. Kukhathamiritsa kwadongosolo kwamakina
Mapangidwe a bend: Pewani kupindika kumanja ndikugwiritsa ntchito utali wopindika waukulu (R≥3D, D ndi m'mimba mwake chitoliro) kuchepetsa nkhawa ndende; Mukayala mapaipi angapo, amagawidwa mofanana kuti agwirizane ndi mphamvu za radial.
Kulimbitsa dongosolo: Onjezani mphete zothandizira (kutalika≤1.5m) kapena zomangira zapakati mpaka zowongoka zazitaliKutentha chubu kuteteza mapindikidwe a chubu thupi pansi kuthamanga kwambiri; Gawo lolumikizana pakati pa flange ndi thupi la chitoliro limatenga malo osinthira (gradient groove welding) kuti apititse patsogolo kukana kwa misozi ya weld.
2. Kusindikiza ndi kupanga kugwirizana
Njira yowotcherera: Thupi la chitoliro ndi flange zimalowetsedwa mokwanira (monga TIG welding + filler waya), ndi 100% X-ray kuyesa (RT) kapena kuyesa kulowa mkati (PT) kumachitika pambuyo kuwotcherera kuti zitsimikizire kuti msoko wa weld ulibe pores ndi ming'alu;
Thandizo lokulitsa: Chubu chosinthira kutentha chimalumikizidwa ndi mbale ya chubu pogwiritsa ntchito njira ziwiri zowonjezera ma hydraulic ndi kusindikiza kusindikiza. Kuwonjezeka kwamphamvu ndi≥kuwirikiza kawiri ntchito yoletsa kutayikira kwapang'onopang'ono kuchokera kumabowo a mbale ya chubu.
3,Kupanga njira: kuwongolera mosamalitsa zolakwika ndi kusasinthika
1. Kuwongolera kulondola kwa makina
The kudula chitoliro utenga laser / CNC kudula, ndi mapeto nkhope perpendicularity≤0.1 mm; flange kusindikiza pamwamba roughness≤Ra1.6μ m, bolt dzenje yunifolomu kugawa cholakwika≤0.5mm, kuonetsetsa mphamvu yunifolomu pa kukhazikitsa.
Magnesium oxide powder kudzaza: kugwiritsa ntchito ukadaulo wa vibration compaction, kudzaza kachulukidwe≥2.2g/cm³, kupewa kutentha kwambiri komweko kapena kulephera kwa kutchinjiriza komwe kumachitika chifukwa cha magawo opanda kanthu (kukana kwa insulation≥100MΩ/ 500V).
2. Kupsinjika maganizo ndi kutsimikizira
Kuyesa kusanachitike fakitale:
Mayeso a Hydrostatic: Kuthamanga kwa mayeso ndi 1.5 nthawi yogwira ntchito (monga 10 MPa yogwira ntchito ndi 15 MPa test pressure), ndipo palibe kutsika kwapakati mutatha kugwira kwa mphindi 30;
Mayeso a Pressure (yomwe imagwira ntchito pama media a gasi): Kuthamanga kwa mayeso ndi 1.1 kuwirikiza kaphatikizidwe kakugwira ntchito, kuphatikizika ndi kuzindikira kwa helium mass spectrometry leak, ndi kutayikira kwa≤1 × 10 ⁻⁹mba· L/s.
Kuyesa kowononga: Zitsanzo zimagwiritsidwa ntchito poyesa kuthamanga kwa kuphulika, ndipo kuthamanga kwa kuphulika kuyenera kukhala≥3 kukakamiza kugwira ntchito kuti mutsimikizire malire achitetezo.
4,Kusintha kwa magwiridwe antchito: kuthana ndi zovuta zogwirira ntchito
1. Kulipiritsa kukulitsidwa kwamafuta
Pamene kutalika kwachubu chotenthetsera is ≥2m kapena kusiyana kwa kutentha kuli≥100℃, cholumikizira cholumikizira cha ma waveform kapena cholumikizira chosinthika chiyenera kukhazikitsidwa kuti chibwezere kusinthika kwamafuta (kuchulukitsa kuchulukaΔ L=α L Δ T, kuα ndi mzere wokulirapo wa chinthucho) ndikupewa kulephera kusindikiza kwa flange chifukwa cha kupsinjika kwa kutentha.
2. Kuwongolera katundu pamwamba
Makanema othamanga kwambiri (makamaka magesi) amakhudzidwa ndi kutenthedwa kwapanyumba ndipo amafunikira kuchepetsa kuchuluka kwapamtunda (≤8W/cm²). Powonjezera chiwerengero kapena m'mimba mwakeKutentha chubus, kubalalitsa kachulukidwe ka mphamvu, ndikuletsa makulitsidwe kapena kukwapula kwa zinthu (monga katundu wapamtunda≤6W/cm² pa kutentha kwa nthunzi).
3. Media ngakhale kapangidwe
Pamadzi othamanga kwambiri okhala ndi tinthu tating'onoting'ono/zonyansa, chotchinga chosefera (cholondola cha≥100 mauna) kapena chivundikiro chowongolera chiyenera kukhazikitsidwa polowera chubu chotenthetsera kuchepetsa kukokoloka; Makanema owononga amafunikira chithandizo chowonjezera chapamwamba / kupopera mbewu mankhwalawa (monga zokutira za polytetrafluoroethylene, kukana kutentha.≤260℃).
5,Standard ndi makonda kapangidwe
Perekani malipoti a zinthu, kuyenerera kwa ndondomeko zowotcherera (PQR), ndi malipoti oyesa kuthamanga motsatira mfundo za dziko (GB 150 "Zotengera Zopanikizika", NB/T 47036 "Electric Heating Elements") kapena miyezo yapadziko lonse (ASME BPVC, PED 2014/68/EU).
Kuti tikwaniritse zosowa zapadera za makasitomala (monga kutenthetsa kwamphamvu kwa API 6A zida zam'mutu komanso kutentha kosasunthika m'nyanja yakuya), timagwirizana ndi makasitomala kuti tiyese zinthu zogwirira ntchito (monga kusanthula komaliza kwa kugawa nkhawa ndi kukhathamiritsa kwa gawo la CFD) ndikusintha mawonekedwe a flange (monga ma flange apadera opangidwa ndi sulfure).
fotokoza mwachidule
Kupyolera mu kukhathamiritsa kwathunthu kwa "material strength guarantee→structural load resistance design→kuwongolera kulondola kwa kupanga→kuyesa ndi kutsimikizira kutsekedwa-loop", theflange magetsi Kutentha chubu akhoza kukwaniritsa ntchito yodalirika pansi pazifukwa zazikulu zamagetsi. Chofunikira ndikuwongolera mphamvu yonyamula mphamvu, kusindikiza, komanso kukhazikika kwanthawi yayitali, ndikuganizira mawonekedwe a kasitomala (kutentha, corrosiveness, flow rate) kuti apangidwe, pomaliza kukwaniritsa zofunikira zachitetezo cha kuthamanga kwamadzi / kuthamanga kwa mpweya.≥1.5 nthawi mapangidwe magawo.
Ngati mukufuna kudziwa zambiri za mankhwala athu, chondeLumikizanani nafe!
