Puas yuav ua rau lub cub tawg kub sensor rov qab los ntawm nws tus kheej?

Feem ntau, malfunctioning furnace kub sensors tsis kho lawv tus kheej. Qhov laj thawj tseem ceeb, uas yuav tsum muaj kev cuam tshuam ncaj qha, yog xoob, oxidation, lossis kev sib txuas ntawm lub cev.

1. Vim li cas ho tsis kho nws tus kheej?

Txheej oxide tsis tu ncua: Sij hawm dhau los, cov txheej txheem tiv thaiv uas tau tsim nyob rau ntawm cov terminals vim qhov kub ntawm -kub oxidation yuav ua rau tsis zoo dua li ploj mus ntawm nws tus kheej.

Kev sib txuas xoob tsis tuaj yeem ua tus kheej - xauv: Thaum cov ntsia hlau lossis cov khoom sib txuas xoob, lawv yuav tsis cia li kaw; xwb, lawv tsuas yog loosen ntau nyob rau hauv teb rau kev co thiab thermal expansion thiab contraction.

Tsis muaj tus kheej - kho cov txheej txheem rau kev cuam tshuam cov teeb liab: Tsis zoo li software, cov teeb liab sensor tsis tuaj yeem "rebooted thiab kho" vim yog kev sib txuas xoob lossis qhib circuits.

Cov lus ceeb toom tswv yim: Ib lub chaw tsim khoom ib zaug tsis quav ntsej txog qhov hloov pauv vim lawv xav tias nws yog "tus kheej- rov qab," uas ua rau muaj kev tshem tawm tsib pawg ntawm H13 pwm vim tsis txaus tempering thiab tsis tshua muaj zog.

2. Tej yam laj thawj rau "False Recovery"

Qhov tshwm sim

Yog vim li cas

Kev phom sij

Qhov ntsuas kub yog ib ntus khov kho.

Kev sib cuag ib ntus yog tsim ntawm qhov chaw sib cuag los ntawm thermal expansion thiab contraction.

Kev tswj qhov kub tsis raug yuav tshwm sim los ntawm cov viav vias tom ntej.

Kub variations tshwm sim tsawg zaus.

Cov txheej oxide ib ntus ua los yog vibrates tsawg dua.

Qhov teeb meem tseem nyob thiab tuaj yeem rov qab los.

PID tswj feem ntau stabilizes

Temperature stability yog misjudged los ntawm kev tswj qhov system

Nws muaj peev xwm hais tias lub cub tawg qhov kub ntawm qhov sib txawv.

Kev nkag siab zoo: "Nto stability ≠ kev tshem tawm txhaum"; kev pom zoo yuav tsum tau kuaj lub cev.

3. Cov txheej txheem tuav tsim nyog

Nres lub tshuab tam sim ntawd rau kev daws teeb meem: Nres cov txheej txheem tempering yog tias koj pom qhov hloov pauv, flashing, lossis tsis sib xws.

Ua ib qho kev sim ntsuas lub teeb los ntawm maj mam tapping cov xaim terminals thaum lawv ua haujlwm; yog tias qhov kub thiab txias hloov, kev sib cuag tsis zoo raug txheeb xyuas.

Tua lub hwj chim thiab tshuaj xyuas cov xaim. Rov kho cov ntsia hlau, tshem tawm cov txheej txheem oxide, thiab siv cov tshuaj tiv thaiv - oxidation lubricant.

Hloov cov khoom qub, xws li cov raj tiv thaiv, cov khoom siv hluav taws xob, lossis cov xaim them nyiaj.

Kev txheeb xyuas qhov sib piv: txhawm rau xyuas kom muaj kev nyeem ntawv ruaj khov thaum kho, sim siv cov thermocouple ib txwm nyob rau tib lub sijhawm.

"Nres tam sim ntawd yog tias muaj qhov txawv txav, tshawb xyuas kom meej ua ntej rov siv dua" yog ib txoj hauv kev nyab xeeb uas pab tiv thaiv cov khoom loj los ntawm kev xav tau.
