Dab tsi yog flange ruaj khov -mounted sojntsuam-hom thermocouple

Tsau flange-mounted sojntsuam- hom thermocouples muab cov txiaj ntsig tseem ceeb ntawm kev kub siab ua haujlwm, muaj zog vibration tsis kam, thiab kev saib xyuas yooj yim, ua rau lawv qhov ntsuas kub tsis tseem ceeb hauv kev lag luam teeb meem cuam tshuam nrog kev kub siab, txoj kab uas hla loj, thiab corrosive media. Lawv cov qauv kev sib txuas thiab cov qauv tsim qauv ua rau lawv yog ib qho ntawm cov kev ntsuas kub siab tshaj plaws thiab nyab xeeb tshaj plaws hauv kev lag luam automation systems niaj hnub no.

 

Structure thiab Sealing Mechanism

Lub flange ruaj khov-mounted sojntsuam- hom thermocouple muaj plaub yam: lub thermocouple caij, magnesium oxide rwb thaiv tsev txheej, lub raj tiv thaiv, thiab flange txuas. Cov khoom siv thermocouple siv K-hom (nickel-chromium/nickel-silicon) los yog E-type (nickel-chromium/copper-}nickel) alloy hlau, welded los ua qhov ntsuas kub sib txuas; cov txheej rwb thaiv tsev yog ua los ntawm siab -purity magnesium oxide hmoov, kom ntseeg tau hluav taws xob sib cais thiab sib npaug ntawm cov cua sov; Cov khoom siv tiv thaiv raj raug xaiv raws li kev ua haujlwm, siv 316L stainless hlau (corrosion{11}}resistant), Inconel 600/625 (siab-kub oxidation resistant), los yog corundum ceramic (ultra- kub rwb thaiv tsev); flange kev twb kev txuas yog lub pob tw-welded los yog plam{17}} ntawm steel flange, ua raws li ASME B16.5 thiab JB/T 8622 qauv. Lub flange sealing nto feem ntau yog lub ntsej muag tsa (MF) lossis tus nplaig thiab zawj lub ntsej muag (TG), yuav tsum muaj qhov sib txuam nrog cov khoom siv sib txuas kom ua tiav siab - siab sealing.

 

Sealing Materials thiab Pressure Adaptability

Flange sealing cia siab rau cov hlau- qhov txhab gaskets (316L stainless hlau sawb + saj zawg zog graphite) los yog hloov tau graphite gaskets, uas tuaj yeem tiv taus kev ua haujlwm siab ntawm 10-25 MPa thiab siab - qhov kub thiab txias ib puag ncig ntawm 800-1300℃. Nyob rau hauv corrosive media (xws li chloride ions, acidic chav), PTFE-coated gaskets yuav siv tau kom tsis txhob muaj hlau ion paug. Lub sealing nto yuav tsum tau muab ntxuav kom huv si ua ntej kev teeb tsa, tsis muaj cov pa roj carbon dub, cov roj stains, radial khawb, lossis qhov pits, kom ntseeg tau tias lub siab tsis sib xws ntawm lub gasket thiab tiv thaiv kev sib tshuam.

 

Core Application Scenarios

Kev lag luam Petrochemical: Catalytic cracking reactors, siab - cov kav dej siab hauv hydrogenation units, distillation kem sab saum toj tswj kub

Kev Lag Luam Hluav Taws Xob: Boiler superheaters, reheaters, cov kav dej loj

Kev Lag Luam Metallurgical: Hluav taws xob arc rauv phab ntsa, nruam casting crystallizer txias dej tshuab

Nuclear Energy Systems: Lub hauv paus Circuit Court coolant kub xyuas (yuav tsum muaj siab -purity Inconel khoom)

Pharmaceutical and Food Industries: Sanitary flange thermocouples (daim iav polished, tsis tuag-angle tsim) ntsib GMP cov qauv

 

Calibration thiab Lifespan Management

Calibration Cycle: 12 months under normal operating conditions; 6 months for high-temperature cycling (>600 degree) los yog corrosive ib puag ncig

Calibration Method: Kev sib piv txoj kev, muab tso rau hauv tubular calibration rauv (± 0.2℃/ min stability) ua ke nrog ib tug S- hom qauv thermocouple, sau cov thermoelectric peev xwm ntawm 300 degree, 600 degree, thiab 900℃. Kev ua yuam kev tsawg dua lossis sib npaug rau ± 1.5℃(K-hom Class III)

Kev Ntsuas Kev Ntsuas Kev Ntsuas: Thermoelectric muaj peev xwm drift tus nqi (tsawg dua lossis sib npaug ntawm 5μV / xyoo), kev tiv thaiv kev tiv thaiv (Ntau dua lossis sib npaug rau 100MΩ @ 500VDC), tiv thaiv tube oxidation thickness (tsawg dua lossis sib npaug rau 0.1mm / xyoo)

Typical Lifespan: 5–8 years in medium and low-temperature environments; 2–4 years in high-temperature cycling (>800 degree)
