Fault Classification & Scientific Replacement Standard for Metal Plating Heating Equipment
Kev hloov qhov muag tsis pom kev ntawm cov cua kub tsis zoo thiab ncua sij hawm hloov cov khoom tsis zoo yog cov teeb meem tshwm sim hauv kev tswj cov khoom siv hluav taws xob rhiav. Ntau pab pawg tsim khoom tsis muaj cov qauv ntsuas kev tshawb fawb tsis raug, ua rau tsis tsim nyog cov nqi pov tseg thiab rov ua tsis tiav. Distinguishing me me faults thiab irreversible aging faults, thiab txuam thermocouple kub cov ntaub ntawv rau kev txiav txim, muaj peev xwm paub txog cov khoom raug tswj thiab kev tswj tus nqi zoo.
Kev ua haujlwm me me attenuation faults tsis xav tau kev hloov khoom siv. Qhov kub nce qeeb qeeb thiab me me lub zog hloov pauv feem ntau yog tshwm sim los ntawm qhov seem seem tsub zuj zuj thiab thermocouple sensing deviation. Kev tu thiab cov ntaub ntawv calibration tuaj yeem rov qab kho cov cuab yeej ua tau zoo yam tsis muaj kev hloov raj. Cov kev ua txhaum me me no yuav tsis cuam tshuam rau kev ruaj ntseg ntawm cov txheej txheem electroplating thiab cov khoom zoo tom qab kev saib xyuas yooj yim.
Kev laus tsis zoo yuav tsum tau npaj hloov. Hauv zos me ntsis corrosion pits, nruam fais fab attenuation ntawm 2% -5% thiab tsis tu ncua kub drift tom qab calibration yog rau nruab nrab cov laus lub xeev. Txawm hais tias cov cuab yeej tseem tuaj yeem ua haujlwm ib txwm, qhov kev ua haujlwm ruaj khov tau txo qis. Kev npaj hloov pauv nyob rau hauv qhov sib txawv ntau lawm tuaj yeem zam qhov tsis ua haujlwm tam sim ntawd cuam tshuam rau kev tsim khoom tas mus li.
Cov kev ua txhaum loj heev yuav tsum tau hloov chaw kaw tam sim. Tube phab ntsa perforation thiab to, tsis zoo rwb thaiv tsev tsis ua hauj lwm, nruam hluav taws xob to alarm thiab uncorrectable thermocouple loj deviation yog irreversible functional failures. Kev ua haujlwm tsis tu ncua yuav ua rau muaj kev nyab xeeb loj thiab cov khoom lag luam tsis tsim nyog txaus ntshai, yuav tsum tau hloov cov khoom siv tam sim.

Hloov cov cua kub raj & recalibrate system |
Raws li cov ntaub ntawv tswj cov khoom siv, kev tshawb fawb tsis raug muab pov tseg tuaj yeem txo cov nqi hloov khoom siv tsis tsim nyog los ntawm 35% thiab tshem tawm 100% ntawm qhov kev pheej hmoo raug kaw los ntawm cov cua kub tsis ua haujlwm. Kev txiav txim siab ua ke nrog cov ntaub ntawv ntsuas kub ntawm cov thermocouple ua kom lub hom phiaj thiab qhov tseeb ntawm kev ntsuas qhov yuam kev.
Cov cuab yeej siv kev ua txhaum kev kuaj xyuas tuaj yeem ntsuas qhov ntsuas kev laus ntawm cov khoom siv hluav taws xob thiab cov kev pabcuam seem, tsim cov phiaj xwm hloov tsim nyog, thiab paub txog kev tswj xyuas cov khoom siv cua sov electroplating.
