Overheating ntawm hluav taws xob cua sov daim kab xev tuaj yeem yooj yim hlawv cov kav dej.

Overheating ntawm hluav taws xob cua kub cab yog qhov teeb meem loj. Cov cua sov ntau dhau yuav scalkes ntau dhau, ua rau cov khoom siv tsis zoo, thiab txawm tias muaj kev sib tsoo ib puag ncig ntawm kev thaiv kev thiab cov plua plav, ua rau hluav taws kub. Txawm hais tias nyob rau hauv cov chaw nyob lossis chaw teeb tsa, qhov no tuaj yeem ua rau cov khoom siv kev puas tsuaj lossis kev nyab xeeb. Nco ntsoov cov ntsiab lus tseem ceeb no kom ua kom muaj kev pheej hmoo ntawm kev kub ntxhov ntawm kev kub ntxhov.

** Thawj taw tes tseem ceeb: ** Xaiv hom kev ua cua sov cable kom phim koj qhov ntsuas kub. Cov xwm txheej sib txawv yuav tsum muaj cua sov cable nrog qhov kub kub tiv thaiv kev ntsuas. Yog tias cov cua sov xaiv cable qhov kub tsis kam yog qis dua li qhov yuav tsum tau ua, nws yooj yim rau overheat. Piv txwv li, txhim kho ib qho 80℃tus kheej- kev tswj hwm cable nyob rau hauv lub zog puv npov tas li, uas ua rau overheating. Cov hluav taws xob cua kub tas nrho yuav tsum tau ua ke nrog cov ntsuas cua sov kom tsis txhob muaj kev tswj hwm kub. Lub tsev pheeb suab creatakenly siv tsev neeg 60 depe Kub {{ov {ove {ove {istant cua sov cable nyob rau 80 degrch cov raj xa khoom; Tom qab 3 teev, cable overheated, scalding lub raj xa dej thiab ua rau muaj tshuaj lom muag tshuaj. Xaiv cov cua kub sab xis nrog kev sib txuam kub ua rau kub siab yog qhov tseem ceeb rau kev zam dhau kev kub ntxhov.

** Cov ntsiab lus thib ob tseem ceeb: ** Nruab ib qho ntsuas kub heev rau tiag - lub sijhawm ntsuas kub. Thaum tus kheej - Kev tswj hwm cua sov muaj kev tswj qhov kub thiab txias, ntxiv ib qho kev tiv thaiv qhov kub tau muab ob npaug kev tiv thaiv. Tom qab teeb tsa lub hom phiaj kub, nws tau txiav tawm yog tias qhov ntsuas kub tshaj qhov txwv. Lub zog siv hluav taws xob tsis tu ncua lub zog yuav tsum muaj lub ntsuas kub; Txwv tsis pub, nws yuav tsis tu ncua overheat. Nws raug nquahu kom xaiv cov ntse ntswv cua sov nrog ib qho kev ntsuas zaub uas pom qhov kub thiab txias hauv qhov ntsuas kub tsawg dua lossis sib npaug. Ib tus neeg nyob hauv nruab nrab nruab thermal tracing rau hnub ci taub rhaub dej kub kav tsis muaj cua sov. Nyob rau lub caij ntuj no, cov tracing overheated nyob rau hauv tsawg kub, scalding lub raj yeeb nkab rwb thaiv tsev. Tom qab kev txhim kho lub ntsuas kub, qhov kub kub nyob ruaj khov ntawm 5-8 degree, thiab tsis muaj teeb meem overheating.

Lub ntsiab lus thib peb: Zam kev sib sau sib txuam los tiv thaiv cov cua sov ntxiv. Overlapping Thermal tracing tuaj yeem ua rau muaj cua sov hauv zos kom swb rau kev poob siab, ua rau muaj kev kub ntxhov tam sim ntawd thiab overheating. Txawm tias tus kheej -} tswj cov cua sov cua sov tuaj yeem tshaj nws qhov kub tsis kam vim yog cua sov tsis zoo. Thaum lub sij hawm installation, kev sib txuas lossis cov kauv kev teeb tsa yuav tsum muaj, nrog kev sib cav ntau dua lossis sib npaug ntawm qhov dav ntawm cov thermal tracing. Kev sib tshooj kuj tseem txwv tsis pub nws khoov. Ntawm qhov chaw tsim kho, sib tshooj thiab wermal ntawm thermal tracing rau overheating tom qab 2 teev kev ua haujlwm, scalding cov kav dej thiab zes cov rwb thaiv tsev. Tom qab Reinstalling raws li cov lus qhia tshwj xeeb, tsis muaj kev pheej hmoo ntawm overheating heev, ua rau pom qhov tseem ceeb ntawm txoj kev teeb tsa. Lub ntsiab lus thib plaub: kev kuaj tsis xws li ib txwm thiab saib xyuas kom sai tau txheeb xyuas cov xwm txheej muaj peev xwm. Tshawb xyuas cov cua sov cable txhua lub lim tiam rau kev puas tsuaj rau cov xov tooj ntawm lub ntsej muag los tiv thaiv cov tsheb ciav hlau tsis muaj zog. Ntsuas cov rwb thaiv tsev tsis kam txhua hli nrog multometer; ib qho tsis kam<50MΩ may indicate a short circuit and overheating risk. Before high-load use in winter, calibrate the thermostat to ensure accurate temperature control. A chemical plant failed to conduct regular inspections, resulting in the heat tracing cable overheating due to core wire aging, scalding oil pipelines and incurring tens of thousands of yuan in repair costs. Regular maintenance can detect overheating hazards early.

Txoj kev pheej hmoo ntawm overheating hauv hluav taws xob cua sov yuav tsum tau zam ntawm qhov chaw. Xaiv txoj cai hom, txhim kho qhov tseeb ntsuas ntsuas sov, thiab kev saib xyuas kom zoo, thiab kev saib xyuas kom tsis tu ncua yog plaub qhov tseem ceeb. Ua raws li cov theem no tuaj yeem tiv thaiv kev kub siab- kub hlawv rau raj dej thiab cov kev nyab xeeb thiab ruaj khov ua haujlwm ntawm hluav taws xob cua sov hauv ntau qhov xwm txheej.
