Yuav Ua Li Cas Thermocouple Short-Circuit Faults Thaum Kub Khiav Nruam Ntau Lawm

Thermocouple luv luv-circuit yog qhov txhaum thaum muaj xwm txheej ceev, uas ua rau cov cua kub khiav cov cua sov tsis tu ncua tso tawm tag nrho lub zog, lub manifold overheating, cov yas carbonization thiab cov khoom nozzles tuaj yeem tshwm sim. Ntau tus neeg ua haujlwm tsis tau tsim cov txheej txheem pov tseg thaum muaj xwm txheej ceev, thiab hloov pauv lub zog lossis tshem tawm cov pwm ntawm qhov xav tau, ua kom lub sijhawm poob qis thiab ua rau muaj kev puas tsuaj ntxiv rau cov khoom kub khiav. Kab lus no piav qhia txog cov txheej txheem kev ua haujlwm tiav los ntawm - qhov kev txiav txim txhaum cai ntawm qhov chaw, kev tiv thaiv kev kaw thaum muaj xwm txheej ceev, kev ua txhaum hauv paus ua rau kev tshuaj xyuas tom qab- kho qhov tseeb, qhia cov neeg ua haujlwm saib xyuas kom muaj kev nyab xeeb tshem tawm luv luv - Circuit Court faults yam tsis muaj kev puas tsuaj pwm thiab cov cuab yeej tswj kub.

Thawj kauj ruam: Kev txiav txim siab ceev ceev, lub zog ruaj ntseg cuam tshuam yam tsis muaj kev cuam tshuam cov pwm. Yog tias tus tswj qhov kub thiab txias tshwm sim ultra- qhov ntsuas kub qis thiab qhov ntsuas kub tam sim no tseem nyob rau qhov siab tshaj plaws, nws tuaj yeem raug ntsuas ua ntej raws li thermocouple luv- Circuit Court txhaum. Tam sim ntawd qhib lub tshuab kaw lus-tagout kev ua haujlwm kom txiav tawm tag nrho cov khoom siv hluav taws xob ntawm lub ntsuas kub tswj txee, tsis yog tsuas yog ib qho chaw cua sov hloov. Qhov seem tam sim no nyob rau hauv cov cua kub kauj yuav ua rau cov cua kub khiav mus tas li, uas yuav ua rau lub zos overheating thiab cov khoom to. Fais fab tuag: txias kub khiav kub kom qis dua 120℃kom tsis txhob muaj kev kub hnyiab thaum tom qab dismantling. Siv ib lub multimeter los ntsuas qhov tsis kam ntawm cov thermocouple connector ntawm tus maub los kawg. Yog tias qhov kev tiv thaiv ntawm qhov zoo thiab qhov tsis zoo ntawm cov xaim nyob ze rau xoom, nws qhia tau hais tias lub voj voog sensor luv luv, thiab tej zaum yuav txawv ntawm qhov teeb meem ntawm Circuit Court board luv Circuit Court.

Qhov thib ob yog kev tshuaj xyuas thiab segmentation kom pom qhov luv luv -circuit generation point, nrog rau qhov txuas txuas txuas, sab nraud txuas hlau seem thiab armored sensing taub hau. Ua ntej, tshem tawm lub thermocouple ntsaws ntawm tus maub los, sim qhov kev tiv thaiv ntawm tus pin plug ntawm nws tus kheej. Yog tias qhov kev tiv thaiv nyob ze ze rau xoom, qhov txhaum tshwm sim ntawm lub ntsaws ntsaws, feem ntau tshwm sim los ntawm cov dej tsis sib haum, cov roj hmab yas thiab cov pa roj carbon plua plav sib sau ntawm ob tus pins. Yog tias qhov ntsaws ruaj ruaj zoo li qub, tshem tawm cov xaim txuas ntxiv thiab lub cev muaj zog thermocouple, tshem tawm cov kab hluav taws xob sib txuas ntawm lub pwm sab, ntsuas ob qhov sib npaug. Qhov luv luv ntawm cov xov hlau txuas sab nraud feem ntau yog tsim los ntawm kev puas tsuaj ntawm cov ntaub qhwv sab nraud, nthuav tawm cov hlau hlau thiab kev sib cuag ntawm cov khoom zoo thiab tsis zoo tom qab extrusion. Yog hais tias lub plug thiab extension hlau yog ib txwm, qhov luv luv - Circuit Court txhaum tshwm sim nyob rau hauv lub armored sheath ntawm lub taub hau sensing, vim yog nkag mus ntawm noo noo, pulverization ntawm insulating hmoov, perforation ntawm sheath thiab cov pa roj carbon buildup nyob rau hauv lub raj.

Kauj Ruam 3: Kev faib cov hom phiaj tshem tawm los ntawm luv luv - qhov chaw nyob hauv Circuit Court. Rau lub davhlau ya nyob twg plug luv luv -circuit vim plua plav thiab ya raws: ntxuav lub plug pins nrog anhydrous cawv, qhuav tag nrog cua txias phom thiab siv lub tsho tiv no ntawm insulating anti- xeb roj los tiv thaiv ya raws thiab conductive plua plav. Yog hais tias lub luv luv Circuit Court yog tshwm sim los ntawm kev puas tsuaj rau lub extension hlau sheath: txiav tawm lub puas hlau seem, splice siv txuam thermocouple alloy taub qab connectors thiab foob nrog siab - kub kub shrink tubing; yog tias qhov kev puas tsuaj ntev tshaj 30cm, hloov tag nrho cov seem ntawm txuas txuas ncaj qha kom tsis txhob rov qab luv dua -circuit ntawm qhov sib txuas. Rau luv luv Circuit Court ntawm lub taub hau nrog cov armored sheath, hmoov rwb thaiv tsev tsis tuaj yeem kho los ntawm kev ntxuav thiab ziab, thiab tag nrho cov thermocouple yuav tsum tau hloov tag nrho; Nws raug txwv tsis pub siv txuas ntxiv tom qab ziab yooj yim vim tias cov hluav taws xob luv luv yuav rov tshwm sim tom qab rov- cua sov. Corrosion perforation ntawm lub sheath tshwm sim los ntawm luv luv-circuit (corrosive yas volatiles), hloov mus rau Inconel anti{13}}corrosion sheath thermocouple los tiv thaiv kev rov ua yuam kev.

Kauj Ruam 4: Tag nrho - ua haujlwm pov thawj tom qab kho kom tsis txhob muaj qhov tsis xws luag zais ntxiv. Tom qab cov thermocouple kev txhawj xeeb yog hloov lossis kho, ntsaws rau hauv dua, lub zog siv maj mam thiab ua ntu ntu qis - kub cua sov hom kom maj mam nce kub khiav kub es tsis txhob ncaj qha tsim qhov kub ntau lawm. Txuas ntxiv mus xyuas qhov kub thiab txias tam sim no rau 30 feeb. Yog hais tias qhov kub thiab txias nce zoo yam tsis muaj kev ceeb toom poob tam sim no thiab lub viav vias tam sim no feem ntau nrog kev hloov kho lub zog, qhov luv luv - Circuit Court txhaum raug tshem tawm tag nrho. Siv lub megohmmeter los xyuas qhov rwb thaiv tsev ntawm cov thermocouple kho. Lub rwb thaiv tsev tiv thaiv yuav tsum yog ntau tshaj 500MΩ rau kev tsim khoom. Yog tias qhov ntsuas kub tseem qhia tau tias tus nqi qis qis tom qab hloov pauv, tshuaj xyuas seb tus tswj hwm channel Circuit Court puas puas los ntawm luv luv -circuit tam sim no thiab hloov cov channel module hauv lub sijhawm.

Kev tiv thaiv kev saib xyuas txhua hnub ua rau nws tsis tshua muaj kev cuam tshuam luv luv . 2. Ntxuav cov roj pos huab thiab cov pa roj carbon plua plav ntawm cov thermocouple plug terminals tsis tu ncua txhua ob lub lis piam . 3. Tsis txhob xaim cov thermocouple xaim nyob rau hauv qis qis ntawm cov pwm. 4. Rau cov kab ntau lawm nrog cov yas corrosive, ob npaug . 5. cov ntaub ntawv pov thawj yuav tsum tau muab tso rau hauv thermocouple sab nrauv ntawm cov hlau txuas ntxiv rau kev puas tsuaj txhua lub hlis, thiab hloov cov hlau puas ua ntej.
