Txoj cai ua haujlwm

Pipeline electric heater yog ib yam khoom siv hluav taws xob siv hluav taws xob los hloov nws mus rau thermal zog rau cov khoom siv cua sov uas yuav tsum tau ua. Thaum lub sijhawm ua haujlwm, qhov nruab nrab ntawm cov kua nruab nrab kub qis nkag mus rau hauv nws qhov nkag hauv qhov siab, ntws los ntawm cov kev sib hloov cua sov tshwj xeeb hauv cov hluav taws xob cua sov, thiab ua raws txoj hauv kev tsim los ntawm cov dej thermodynamics. Nws nqa tawm qhov kub-kub kub lub zog tsim los ntawm cov hluav taws xob cua sov cov ntsiab lus, nce qhov kub ntawm cov cua sov nruab nrab Lub qhov hluav taws xob ntawm lub tshuab hluav taws xob tso tawm qhov nruab nrab kub kub uas yuav tsum tau ua los ntawm cov txheej txheem. Cov kev tswj xyuas sab hauv ntawm lub tshuab hluav taws xob tuaj yeem tswj cov zis hluav taws xob raws li qhov ntsuas kub ntsuas ntawm lub qhov hluav taws xob, tswj qhov ntsuas kub ntawm qhov nruab nrab ntawm qhov hluav taws xob. Thaum cov khoom cua sov overheats, lub ywj siab overheat tiv thaiv ntaus ntawv ntawm cov cua sov tam sim ntawd txiav tawm lub cua sov lub hwj chim los tiv thaiv cov khoom rhuab los ntawm overheating, uas yuav ua rau coking, degradation, thiab carbonization, thiab nyob rau hauv loj heev, ua puas lub cua sov caij. Qhov no zoo txuas lub neej kev pab cuam ntawm lub tshuab hluav taws xob.

Kev ua haujlwm ntawm daim ntawv thov txheej txheem

Yuav ua li cas pipeline heaters ua haujlwm

1) Txheej txheem cej luam ntawm dej phwj cua sov pipeline hluav taws xob rhaub

Lub tshuab rhaub hluav taws xob yog ib yam khoom siv uas yog siv rau hauv dej phwj cua sov hauv qhov dej phwj kho qhov project. Lub tshuab hluav taws xob hloov hluav taws xob hloov hluav taws xob mus rau hauv lub zog hluav taws xob kom paub txog cov cua sov ntawm cov dej phwj dej cua sov thiab txhim kho kev ua tau zoo thiab zoo ntawm cov txheej txheem dej phwj tuaj.

2) Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab hluav taws xob ntawm cov kav dej phwj tuaj

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab rhaub hluav taws xob hauv cov kav dej phwj tuaj yeem muab faib ua ob ntu: kev hloov hluav taws xob hluav taws xob thiab hloov hluav taws xob.

1. Kev hloov hluav taws xob hluav taws xob

Tom qab cov hlau tsis muaj zog hauv lub rhaub hluav taws xob txuas nrog lub zog hluav taws xob, qhov tam sim no los ntawm cov hlau tsis muaj zog yuav ua rau lub zog poob, uas yog hloov mus rau hauv lub zog hluav taws xob, cua sov lub rhaub nws tus kheej. Qhov kub ntawm lub rhaub dej kub nce nrog qhov nce ntawm qhov tam sim no, thiab thaum kawg lub tshav kub lub zog ntawm lub rhaub dej yog xa mus rau cov kav dej phwj uas yuav tsum tau ua kom sov.

2. Thaum tshav kub kub conduction

Lub tshuab hluav taws xob hloov hluav taws xob hloov hluav taws xob hluav taws xob los ntawm qhov chaw ntawm lub rhaub dej mus rau saum npoo ntawm cov yeeb nkab, thiab maj mam hloov nws raws phab ntsa ntawm cov yeeb nkab mus rau cov dej phwj hauv cov yeeb nkab. Cov txheej txheem ntawm kev siv hluav taws xob tuaj yeem piav qhia los ntawm kev sib npaug ntawm cov hluav taws xob hluav taws xob, thiab nws cov ntsiab lus tseem ceeb muaj xws li cov khoom siv yeeb nkab, yeeb nkab phab ntsa thickness, thermal conductivity ntawm tshav kub hloov nruab nrab, thiab lwm yam.

3) Cov ntsiab lus

Lub tshuab hluav taws xob hluav taws xob hloov hluav taws xob hluav taws xob rau hauv lub zog hluav taws xob kom paub txog cov cua sov ntawm cov kav dej phwj cua sov. Nws txoj haujlwm ua haujlwm suav nrog ob ntu: kev hloov hluav taws xob hluav taws xob thiab thermal hloov hluav taws xob, ntawm cov thermal hloov hluav taws xob muaj ntau yam cuam tshuam. Hauv kev siv cov tswv yim, lub tshuab hluav taws xob tsim nyog yuav tsum raug xaiv raws li qhov xwm txheej tiag tiag ntawm cov kav dej cua sov, thiab kev saib xyuas tsim nyog yuav tsum tau ua.

Daim ntawv thov khoom

Pipeline rhaub tau dav siv hauv aerospace, riam phom kev lag luam, tshuaj lom neeg kev lag luam thiab cov tsev kawm ntawv qib siab thiab tsev kawm qib siab thiab ntau lwm yam kev tshawb fawb thiab kev tsim khoom. Nws yog tshwj xeeb tshaj yog tsim rau kev tswj kub tsis siv neeg thiab loj ntws kub kub ua ke nrog cov khoom siv thiab cov khoom siv, cov cua kub nruab nrab ntawm cov khoom tsis yog-conductive, tsis kub hnyiab, tsis tawg, tsis muaj tshuaj corrosion, tsis muaj kuab paug, nyab xeeb thiab txhim khu kev qha, thiab qhov chaw cua sov yog ceev (tswj tau).
