Kev kho dej phwj tuaj hluav taws xob rhaub

Dej phwj kho hluav taws xob rhaub Featured duab

Lus piav qhia luv luv:

Kev kho dej phwj tuaj hluav taws xob yog ib yam khoom siv txuag hluav taws xob ua ntej ua kom sov cov khoom, uas yog ntsia ua ntej cov khoom siv kom paub txog cov cua sov ncaj qha ntawm cov khoom, kom nws tuaj yeem ua kom sov hauv qhov kub thiab txias, thiab thaum kawg ua tiav. lub hom phiaj ntawm kev txuag hluav taws xob. Nws yog dav siv nyob rau hauv pre-heating ntawm hnyav roj, asphalt, huv si roj thiab lwm yam roj. Cov yeeb nkab tso cua sov yog tsim los ntawm ob ntu: lub cev thiab tswj qhov system. Cov khoom cua sov yog ua los ntawm cov yeeb nkab steel hlau ua lub tes tsho tiv thaiv, kub kub tsis kam hlau hlau, crystalline magnesium oxide hmoov, tsim los ntawm cov txheej txheem compression. Qhov kev tswj xyuas yog tsim los ntawm cov digital circuits siab heev, kev sib txuas ua ke ntawm lub zog hluav taws xob, siab rov qab voltage thyristor thiab lwm yam ntsuas kub ntsuas thiab qhov ntsuas kub tsis tu ncua kom ntseeg tau tias lub tshuab hluav taws xob ua haujlwm li qub.

Txoj cai ua haujlwm

Kev kho dej phwj tuaj hluav taws xob ua haujlwm lub hauv paus ntsiab lus yog ua raws li cov txheej txheem ntawm kev hloov hluav taws xob hluav taws xob mus rau hauv tshav kub. Tshwj xeeb, lub tshuab rhaub hluav taws xob muaj cov khoom siv hluav taws xob cua sov, feem ntau yog cov xaim hluav taws xob kub, uas ua kom sov thaum tam sim no dhau mus, thiab qhov tshwm sim tau hloov mus rau cov kua nruab nrab, yog li cua sov cov kua.

Lub tshuab rhaub hluav taws xob kuj tau nruab nrog lub tshuab tswj, suav nrog cov ntsuas kub ntsuas, cov ntsuas kub digital thiab cov khoom siv hluav taws xob hauv lub xeev, uas ua ke tsim kev ntsuas, kev tswj hwm thiab tswj lub voj. Qhov ntsuas kub ntsuas ntsuas qhov ntsuas kub ntawm lub qhov hluav taws xob thiab xa cov teeb liab mus rau cov ntsuas kub digital, uas kho cov zis ntawm cov khoom hauv lub xeev relay raws li qhov ntsuas kub, thiab tom qab ntawd tswj lub zog ntawm lub tshuab hluav taws xob kom tswj tau qhov kub thiab txias. ntawm cov kua nruab nrab.

Tsis tas li ntawd, lub tshuab rhaub hluav taws xob kuj tseem tuaj yeem nruab nrog cov cuab yeej tiv thaiv overheat tiv thaiv kom tsis txhob muaj cua sov los ntawm overtemperature, zam qhov nruab nrab deterioration los yog cov khoom puas tsuaj vim kub kub, yog li txhim kho kev nyab xeeb thiab khoom siv lub neej.

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 hom khoom siv uas yog siv rau cov dej phwj dej 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 tshuab 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, ua kom 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 cov cua sov 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.
