Hluav taws xob cua sov yog siv los tiv thaiv kev tiv thaiv kab mob thiab kev kub ntxhov ntawm cov kav dej, tso tsheb hlau luam, cov cuab yeej ntsuas, thiab cua sov; snowmelt thiab dej khov yaj ntawm txoj kev thiab cov tsev; Thaum tshav kub kub them rau cov txheej txheem ntau lawm, thiab lwm yam. Vim tias cov cua sov tsis ua tiav, nws yog hu ua "kub tracing". Hluav taws xob cua sov tracing yog hu ua "heat tracing" los yog "hluav taws xob tropics", uas yog muab faib ua tus kheej txwv kub hluav taws xob cua sov kab thiab tas li lub zog hluav taws xob cua sov kab.
Raws li kev faib tawm ntawm kev lag luam thiab pej xeem tshwj xeeb kev lag luam, hluav taws xob tracing feem ntau muab faib ua peb pawg:
A: Ib pawg yog hluav taws xob hluav taws xob ntsuas hluav taws xob, xws li: lub zog hluav taws xob tas li hluav taws xob hluav taws xob, hluav taws xob hluav taws xob tsis tu ncua, hluav taws xob tiv thaiv hluav taws xob hluav taws xob, hluav taws xob hluav taws xob hluav taws xob, hluav taws xob hluav taws xob hluav taws xob, hluav taws xob hluav taws xob hluav taws xob, hluav taws xob hluav taws xob hluav taws xob, hluav taws xob hluav taws xob hluav taws xob, hluav taws xob hluav taws xob hluav taws xob thiab hluav taws xob hluav taws xob.
B: Cov qeb thib ob yog kev siv hluav taws xob hluav taws xob hauv hluav taws xob, xws li hnub ci zog tracing, tsis tawg-pov thawj nws tus kheej qhov ntsuas kub hluav taws xob tracing, hluav taws xob hauv pem teb cua sov thiab ntse hluav taws xob cua sov.
C: Peb pawg yog tshwj xeeb hluav taws xob thaum tshav kub kub tracing, xws li: silicone roj hmab hluav taws xob cua sov tracing, hluav taws kub tshwj xeeb hluav taws xob kub tracing, ceramic hluav taws xob tshav kub tracing
Cov zis hluav taws xob ntawm tus kheej tswj qhov kub thiab txias hluav taws xob hluav taws xob yog hais txog qhov tso zis hluav taws xob rau ib chav tsev ntev ntawm cable nyob rau hauv cov xwm txheej uas qhov ntsuas kub ntawm 10 degrees Celsius. Raws li kev faib tawm ntawm cov hluav taws xob hluav taws xob cua sov, muaj peb hom kev tswj tus kheej qhov kub thiab txias hluav taws xob cua sov tracing. Feem ntau hais lus, lub zog cua sov yog tsawg dua 35 watts / meter rau qis hluav taws xob tracing; Nruab nrab lub zog hluav taws xob hluav taws xob hluav taws xob yog qhov hluav taws xob cua sov ntau dua 35 watts / meter thiab tsawg dua 70 watts / meter; Cov cua kub ntau dua 65 watts ib 'meter' yog ib qho hluav taws xob hluav taws xob hluav taws xob siab.
Lub zog hluav taws xob tsis tu ncua hluav taws xob hluav taws xob tuaj yeem muab faib ua ob pawg raws li txoj cai ua haujlwm, hom sib npaug thiab hom series, uas cov hom sib txuas tau muab faib ua ib-theem thiab peb-theem 2 pawg raws li qhov sib txawv ua haujlwm voltage.
Txoj hauv kev ua haujlwm: Lub tsheb npav fais fab ntawm cov khoom no yog 2 (theem ib zaug) lossis 3 (peb-theem) cov kab hluav taws xob sib txuas ua ke, thiab cov xov hlau nickel-chromium cua sov yog qhov txhab ntawm cov ntaub thaiv npog sab hauv, thiab cov cua sov hlau. thiab lub npav npav yog staggered thiab txuas ntawm qhov sib npaug ntawm qhov sib npaug los ua ib qho kev sib txuas tsis tu ncua. Thaum lub tsheb npav txuas nrog 220V lossis 380V voltage, txhua qhov sib txuas resistor heats nyob rau tib lub sijhawm, tsim ib theem ib zaug lossis peb-theem txuas txuas ntxiv hluav taws xob.
Parallel tas li lub zog hluav taws xob hluav taws xob vim yog cov cuab yeej paub tab, cov khoom lag luam zoo, ruaj khov thiab txhim khu kev qha zoo, yooj yim installation thiab siv, dav adaptability, lub neej ntev, yog li nws yog tam sim no dav siv nyob rau hauv tsev thiab txawv teb chaws cov khoom siv hluav taws xob cua sov, tag nrho cov chav, dej kub. Cov chaw cua sov tuaj yeem siv cov khoom lag luam, ntawm qhov siv peb-theem yog tshwj xeeb tshaj yog haum rau qhov ntev-ntev loj-inch pipeline heat tracing. Lub zog tsis tu ncua hluav taws xob tropics tau muab faib ua hom zoo tib yam thiab hom kev txhawb zog raws li cov qauv sib txawv. Feem ntau, faus lossis corrosive gas (kua) qhov chaw yuav tsum raug xaiv raws li hom kev txhawb zog; Marine reinforced hom yuav tsum tau siv nyob rau hauv offshore platforms, docks thiab ntug hiav txwv dej; Cov khoom siv hluav taws xob siv hluav taws xob nrog cov xwm txheej zoo dua tuaj yeem xaiv hom zoo tib yam.
