Dab tsi yog qhov ruaj khov - xov mounting hom sojntsuam thermocouple

Cov qauv thiab cov khoom siv

Hom thermocouple no muaj plaub ntu: qhov ntsuas qhov sib txuas, txheej txheej rwb thaiv tsev, cov raj tiv thaiv, thiab cov xov txuas. Kev ntsuas kev sib txuas siv K- hom (nickel-chromium/nickel-silicon) los yog E-type (nickel-chromium/copper-nickel) thermocouple xov hlau, welded ua ke los ua ib tug thermocouple khub; txheej rwb thaiv tsev yog ua los ntawm siab -purity magnesium oxide hmoov, ntim rau hauv lub raj tiv thaiv kom ua tiav cov hluav taws xob sib cais thiab thermal conduction tshuav; Cov khoom siv tiv thaiv tube raug xaiv raws li kev ua haujlwm: 316L stainless hlau (corrosion-resistant, nruab nrab mus rau qis), Inconel 600/625 (siab kub resistant, resistant chloride ion corrosion), los yog corundum ceramic (ultra- kub, zoo heev rwb thaiv tsev); cov txheej txheem threaded connector yog M27 × 2 lossis 1″NPT, ua raws li JB/T 5518 thiab IEC cov qauv{17}} Cov Qauv Txuj Ci, ua kom muaj kev sib hloov.

 

Txoj Cai Kev Ua Haujlwm thiab Kev Tshaj Tawm Tshaj Tawm Cov yam ntxwv

Raws li cov nyhuv Seebeck, thaum muaj qhov sib txawv ntawm qhov ntsuas qhov kawg thiab qhov kev siv kawg, lub thermocouple Circuit Court tsim ib lub microvolt -theem electromotive quab yuam (tus nqi raug: 40μV / degree), uas tau xa mus rau cov khoom ntsuas ntawm cov xov hlau them nyiaj. Nws cov khoom tso tawm pom qhov ze ntawm - kev sib raug zoo, nrog qhov yuam kev tsawg dua lossis sib npaug li ± 1.5℃hauv 0 ~ 1000℃ntau yam (Hom K, Chav Kawm III). Lub sij hawm teb yog cuam tshuam los ntawm qhov tuab ntawm phab ntsa thaiv phab ntsa: kwv yees li 60-120 vib nas this rau cov raj hlau thiab kwv yees li 120-180 vib nas this rau cov raj ceramic. Nws yog qhov tsim nyog rau kev saib xyuas qhov chaw ruaj khov- lub xeev lossis maj mam hloov qhov kub thiab txias.

 

Core Application Scenarios

Kev lag luam fais fab: Boiler superheater thiab reheater raj phab ntsa ntsuas kub

Kev lag luam Petrochemical: Lub tsho Reactor, siab - qhov kub thiab txias ntawm catalytic cracking units

Kev Lag Luam Metallurgical: Hluav taws xob arc rauv lub qhov ncauj, nruam casting crystallizer txias dej kub

Kev Lag Luam Tshuaj: Siab - cov kav dej siab, ammonia synthesis ntau qhov hluav taws xob

Nuclear Energy Field: Lub hauv paus Circuit Court coolant kub xyuas (yuav tsum tau siab -cov ntaub ntawv purity)

 

Installation thiab Sealing Technical Cov ntsiab lus tseem ceeb

Xov Pre-kev kho mob: Cov khoom siv threaded qhov yuav tsum huv si thiab tsis muaj burrs, thiab xov qhov tob yuav tsum siab tshaj los yog sib npaug rau 1.5 npaug ntawm nominal txoj kab uas hla.

Sealing Material: Plua plav-dawb asbestos hlua (kub tsis kam Ntau dua lossis sib npaug li 800 degree) lossis siab -kub refractory av nplaum yuav tsum tau siv; Teflon daim kab xev thiab silicone sealant raug txwv.

Tightening Torque: 40–60 N·m rau M27 × 2 threads, 60–80 N·m rau M33 × 2 threads. N·m, torque wrench xav tau

Insertion qhov tob: Ntau dua los yog sib npaug li 10-15 npaug ntawm txoj kab uas hla ntawm lub raj tiv thaiv, tsis pub tsawg dua 75 hli hauv siab - cov kua dej siab

 

Hluav taws xob thiab Cold Junction Compensation Specifications

Polarity: Liab hlau tsis zoo (-), daj hlau yog qhov zoo (+)

AK- hom kev them nyiaj xaim yuav tsum tau siv, nrog rau cov txheej thaiv thaiv av ntawm ib kawg.

Qhov kev sib tshuam txias txuas mus rau qhov ntsuas kub tsis tu ncua ntawm lub txee tswj (tsawg dua lossis sib npaug li 100 degree), thiab cov cuab yeej ua rau lub tshuab txias txias tsis siv neeg (AFC) muaj nuj nqi.
