Yim lub ntsiab lus tseem ceeb rau kev txhim kho qhov ntsuas kub tsis kam (RTDs) kom paub meej qhov ntsuas kub kom raug.

Hauv kev lag luam xws li petrochemicals, lub zog tsim hluav taws xob, thiab metallurgy, qhov ntsuas kub tsis kam (RTDs) tau dhau los ua cov cuab yeej tseem ceeb rau kev ntsuas kub vim lawv qhov raug siab (± 0.1 degree) thiab ntev -lub sij hawm ruaj khov. Txawm li cas los xij, kev txheeb xyuas kev lag luam qhia tau tias ntau dua 60% ntawm qhov ntsuas kub ntsuas qhov sib txawv yog los ntawm kev saib xyuas thaum lub sijhawm teeb tsa. Kab lus no yuav txheeb xyuas cov ntsiab lus tshwj xeeb rau RTD kev teeb tsa los pab koj kom ntsuas kev ntseeg tau los ntawm qhov pib.

I. Peb Qhov Tseem Ceeb Ua Ntej -Kev Tshawb Fawb

1. Kev Tshawb Fawb Txog Kev Pom Zoo

• Tshawb xyuas cov kab nrib pleb lossis kev puas tsuaj rau cov txheej tiv thaiv -corrosion ntawm lub tes tsho tiv thaiv (xws li, ntawm cov pob qij txha hauv 316L stainless hlau).

• Micron- theem kev puas tsuaj tuaj yeem ua rau corrosive media intrusion, shortening sensor lifespan txog li 50%.

2. Kev ntsuas kev ua haujlwm ntawm rwb thaiv tsev

• Siv lub megohmmeter los ntsuas qhov kev tiv thaiv ntawm qhov ntsuas kub thiab lub tes tsho.

• The resistance at room temperature must be >100MΩ (kuaj voltage 10-100V DC) los tiv thaiv luv luv Circuit Court thaum ntsuas.

3. Calibration Verification

• Sib piv cov nqi tiv thaiv ntawm 0℃thiab 100℃siv da dej kub tas li.

• Pt100 Class A qhov yuav tsum tau muaj tseeb: 100 ± 0.06Ω ntawm 0 degree, tsis kam piv 1.3850 ± 0.001 ntawm 100 degree.

II. Golden Txoj Cai rau Kev Txhim Kho Qhov Chaw Xaiv

1. Plaub hom kev phom sij uas yuav tsum zam

• Tshav kub qhov chaw cuam tshuam: nyob deb ntawm li qub, lub luj tshib, thiab cov khoom siv hauv qhov chaw tuag (kub qhov kev pheej hmoo cuam tshuam nce 40%)

• Nruab nrab stratification cheeb tsam: Ua ntej cov kav dej ncaj nraim (sab sauv loj dua los yog sib npaug rau 10 npaug ntawm txoj kab uas hla ntawm cov yeeb nkab, hauv qab dej loj dua lossis sib npaug li 5 npaug ntawm cov yeeb nkab txoj kab uas hla)

• Cov chaw hluav taws xob hluav taws xob: Ntau dua lossis sib npaug li 1.5 meters deb ntawm cov zaus hloov pauv thiab lub cev muaj zog tiv thaiv teeb meem cuam tshuam

• Mechanical vibration cov ntsiab lus: vibration damping brackets yuav tsum tau ntsia ze ntawm lub twj tso kua mis thiab compressors

2. Precise tswj ntawm qhov tob tob

• Cov kav dej ib txwm: Ntxig rau qhov nruab nrab ntawm cov kav dej (piv txwv li, 100mm ntxig rau Φ200mm kav)

• Cov kua dej kub thiab kub siab: Kev nkag siab tob dua los yog sib npaug li 75mm lossis cua sov-shrink hom 100mm (kom tiv thaiv lub tes tsho tawg)

• Cov thawv loj / cov nplaim hluav taws xob: 1m ntxig yog txaus rau 4m txoj kab uas hla flues (kom tsis txhob thermal gradient yuam kev)

• Kev teeb tsa tob tshaj 1m: Vertical fixation + kev txhawb nqa ncej (kom tiv thaiv kev khoov deformation)

III. Tsib - txheej txheem installation

Kev ntsuas qhov tseeb: Xov (M27 × 2) los yog flange (DN50) PN16) Dimensional yuam kev Tsawg dua lossis sib npaug li 0.5mm

Tsis yog-kev puas tsuaj drilling: Qhov txoj kab uas hla 0.5-1mm loj dua lub hauv paus (kom tiv thaiv vuam deformation)

Argon arc vuam: Kom tsis txhob slag spatter ua puas lub PTFE hauv ob sab phlu thiab lwm yam anti{0}}corrosion txheej

torque tswj: Sensor screwing quab yuam tsawg dua los yog sib npaug rau 15N·m (overtightening yuav ua rau foob tsis ua hauj lwm)

Waterproof thaiv: Qhov hluav taws xob sib txuas ntawm lub qhov hluav taws xob tig mus rau hauv qab, IP65 tiv thaiv kev ntsuas los tiv thaiv kev sib kis luv luv

Cov kev daws teeb meem tshwj xeeb rau kev khiav hauj lwm: Rau cov yeeb nkab sab nrauv phab ntsa ntsuas kub, siv clamp- hom armored RTDs; lub elastic compression qauv ua tiav xoom-welding installation

IV. Tag nrho lub neej voj voog tu lub tswv yim

• Ua ntej- ua kom: Preheat rau 30 feeb kom ncav cuag thermal sib npaug tom qab siv thawj zaug lossis kaw

• Kev tiv thaiv kev vibration: Siv armored RTDs hauv qhov chaw vibration (3 zaug txhim kho hauv kev co kuj)

• Kev saib xyuas saum npoo: Ntxuav nplai nrog ib daim ntaub mos muag; tsis txhob khawb cov txheej tiv thaiv -corrosion nrog cov khoom tawv

• Calibration voj voog: Qib A platinum RTDs txhua rau lub hlis; Qib B tshuaj xyuas txhua xyoo (saib rau JJG229 tus qauv)

• Cia lub sij hawm kaw: qhov chaw cua nrog cov av noo tsawg dua lossis sib npaug li 80%, deb ntawm cov chloride ion corrosive gases
