Ua kom tau raws li qhov xav tau ntawm cov neeg siv khoom siab rau dej siab thiab cua siab hauv kev tsim ntawmflange hluav taws xob cua sov raj,Kev ua kom zoo tshaj plaws yog xav tau los ntawm ntau qhov ntev xws li xaiv cov khoom siv, kev tsim qauv, txheej txheem tsim khoom, thiab kev txheeb xyuas kev ua haujlwm. Txoj kev npaj tshwj xeeb yog raws li nram no:
1,Kev xaiv cov khoom siv: Txhim kho compressive zog thiab sealing foundation
1. Kev xaiv cov khoom siv yeeb nkab tseem ceeb
Cov ntaub ntawv muaj zog thiab corrosion-resistant yog nyiam rau kev ua haujlwm siab (dej siab≥10MPa lossis cua siab≥6MPa), xws li:
Stainless hlau 316L (tiv taus rau cov xov xwm corrosive, compressive zog≥520MPa);
Incoloy 800 (tiv taus kub, siab siab thiab oxidation, haum rau qhov kub thiab txias ib puag ncig, yield zog≥240MPa);
Titanium alloy / Hastelloy alloy (rau corrosive thiab high-pressure media xws li seawater thiab acid-base daws).
Phab ntsa thickness ntawm cov yeeb nkab yog xam raws li cov qauv ntawm GB / T 151 Thaum tshav kub kub Exchanger los yog ASME BPVC VIII-1, kom ntseeg tau ib tug phab ntsa thickness margin ntawm≥20% (xws li xam cov phab ntsa thickness + 0.5mm kev nyab xeeb yam thaum lub siab ua hauj lwm yog 15MPa).
2. Flange thiab foob sib txuam
Flange hom: Hauv cov xwm txheej kub ntxhov, lub caj dab vuam flanges (WNRF) lossis ib qho flanges (IF) yog siv, thiab lub sealing nto yog xaiv raws li mortise thiab tenon (TG) los yog nplhaib sib koom tes (RJ) kom txo tau txoj kev pheej hmoo ntawm sealing nto to.
Sealing gasket: Xaiv cov hlau qhwv gasket (nrog rau sab hauv thiab sab nraud) (siab tsis kam≤25MPa) los yog octagonal hlau nplhaib gasket (siab siab thiab siab kub, siab tsis kam≥40MPa) raws li cov yam ntxwv ntawm qhov nruab nrab. Cov khoom siv gasket yog sib xws nrog cov khoom siv yeeb nkab (xws li 316L gasket nrog 316L flange).
2,Tus Qauv Tsim: Txhim kho qhov siab thiab kev ntseeg siab
1. Mechanical structure optimization
Khoov tsim: zam lub kaum sab xis khoov thiab siv lub vojvoog loj curvature (R≥3D, D yog cov yeeb nkab txoj kab uas hla) kom txo tau kev ntxhov siab; Thaum nteg tawm ntau cov kav dej, lawv tau muab faib ua symmetrically kom sib npaug radial rog.
Txhim kho cov qauv: Ntxiv cov nplhaib txhawb nqa (qhov sib nrug≤1.5m) los yog built-in central positioning rods mus rau qhov ntev ncajlub raj cua sov los tiv thaiv deformation ntawm lub raj lub cev nyob rau hauv siab siab; Qhov kev sib txuas ntawm lub flange thiab cov yeeb nkab lub cev tau txais ib qho kev hloov pauv tuab (gradient zawj welding) los txhim kho cov kua muag tsis kam ntawm vuam seam.
2. Kev sib khi thiab kev sib txuas tsim
Vuam txheej txheem: Cov yeeb nkab lub cev thiab flange tau nkag mus rau hauv welded (xws li TIG welding + muab tub lim), thiab 100% X-ray kuaj (RT) lossis kev ntsuas nkag (PT) yog ua tom qab vuam los xyuas kom meej tias lub vuam seam tsis muaj qhov hws thiab tawg;
Kev pab nthuav dav: Lub raj xa hluav taws xob txuas nrog lub raj phaj siv ob txheej txheem ntawm hydraulic expansion thiab sealing vuam. Lub expansion siab yog≥ob zaug ntawm kev ua haujlwm siab los tiv thaiv cov pa nruab nrab ntawm lub raj phaj qhov.
3,Cov txheej txheem tsim khoom: nruj tswj xyuas qhov tsis xws luag thiab sib xws
1. Kev tswj qhov tseeb ntawm machining
Cov yeeb nkab txiav txais laser / CNC txiav, nrog lub ntsej muag kawg perpendicularity≤0.1 hli; flange sealing nto roughness≤Rau 1.6μ m, ntsia liaj qhov rooj qhov uniform faib yuam kev≤0.5mm, kom ntseeg tau tias lub zog tsis sib xws thaum lub sijhawm teeb tsa.
Magnesium oxide hmoov filling: siv kev vibration compaction technology, filling ceev≥2.2g / cm3³, kom tsis txhob overheating hauv zos los yog rwb thaiv tsev tsis ua hauj lwm los ntawm hollow seem (cov rwb thaiv tsev tsis kam≥100 MΩ/ 500V).
2. Kev ntsuas kev ntxhov siab thiab kev siv tau
Pre-Factory xeem:
Kev ntsuas hydrostatic: Kev ntsuas siab yog 1.5 npaug ntawm kev ua haujlwm siab (xws li 10 MPa ua haujlwm siab thiab 15 MPa kev ntsuas siab), thiab tsis muaj kev poob siab tom qab tuav 30 feeb;
Kev ntsuas siab (tseem siv tau rau cov xov xwm roj): Kev ntsuas siab yog 1.1 npaug ntawm kev ua haujlwm siab, ua ke nrog helium huab hwm coj spectrometry xau pom, nrog rau tus nqi xau ntawm≤1 × 10 ⁻⁹mbar ua· L/s.
Kev ntsuam xyuas kev puas tsuaj: Cov qauv yog siv rau kev ntsuas tawg, thiab qhov tawg siab yuav tsum yog≥3 npaug ntawm kev ua haujlwm siab los xyuas qhov kev nyab xeeb.
4,Functional adaptation: tiv thaiv kev ua haujlwm nyuaj
1. Thermal expansion them nyiaj
Thaum qhov ntev ntawmlub raj cua sov is ≥2m los yog qhov sib txawv ntawm qhov kub thiab txias yog≥100℃, lub waveform expansion sib koom ua ke los yog hloov tau yooj yim txuas seem yuav tsum tau ntsia los them rau thermal deformation (expansion nyiajΔ L=α L Δ T, qhov twgα yog cov khoom siv linear expansion coefficient) thiab zam flange sealing nto tsis ua hauj lwm los ntawm qhov kub thiab txias sib txawv.
2. Nto load tswj
Cov xov xwm kub siab (tshwj xeeb tshaj yog cov pa roj) yog rhiab rau cov cua sov hauv zos thiab yuav tsum tau txo qis hauv qhov chaw thauj khoom (≤8 W / cm²). Los ntawm kev nce tus naj npawb lossis txoj kab uas hla ntawmlub raj cua sovs, dispersing zog ceev, thiab tiv thaiv scaling los yog khoom creep (xws li nto load≤6 W / cm² thaum lub sij hawm cua sov).
3. Media compatibility tsim
Rau cov kua dej siab uas muaj cov khoom / impurities, lub vijtsam lim (nrog qhov tseeb ntawm≥100 mesh) lossis daim ntawv qhia npog yuav tsum tau muab tso rau ntawm qhov nkag ntawm lub raj cua sov txo erosion; Corrosive media xav tau kev kho deg passivation / txau ntxiv (xws li polytetrafluoroethylene txheej, kub tsis kam≤260℃).
5,Standard thiab customized tsim
Muab cov ntaub ntawv tshaj tawm, cov txheej txheem vuam tsim nyog (PQR), thiab cov ntawv ceeb toom kev ntsuas siab raws li lub teb chaws tus qauv (GB 150 "Pressure Vessels", NB/T 47036 "Electric Heating Elements") lossis cov qauv thoob ntiaj teb (ASME BPVC, PED 2014/68/EU).
Txhawm rau ua kom tau raws li cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom (xws li cov cua kub siab rau API 6A cov khoom siv zoo thiab cov cua kub hauv hiav txwv sib sib zog nqus), peb koom tes nrog cov neeg siv khoom los simulate cov kev ua haujlwm (xws li finite element tsom xam ntawm kev ntxhov siab thiab CFD flow field optimization) thiab kho flange specifications (xws li tshwj xeeb threaded flanges thiab sulfur resistant cov ntaub ntawv).
xaus lus
Los ntawm tag nrho cov txheej txheem optimization ntawm "cov ntaub ntawv muaj zog lav→structural load kuj tsim→manufacturing raug tswj→testing and verification close-loop", covflange hluav taws xob cua sov raj tuaj yeem ua tiav kev lag luam txhim khu kev qha nyob rau hauv high voltage tej yam kev mob. Lub hauv paus tseem ceeb yog txhawm rau sib npaug ntawm qhov muaj peev xwm ua tau zoo, kev sib khi ua haujlwm, thiab kev ruaj ntseg mus ntev, thaum coj mus rau hauv tus account cov yam ntxwv ntawm tus neeg siv khoom nruab nrab (kub, corrosiveness, ntws tus nqi) rau cov qauv tsim, thaum kawg ua tau raws li qhov kev nyab xeeb ntawm cov dej siab / cua siab.≥1.5 npaug ntawm cov qauv tsim.
