Environmental Maintenance Specification: Thermocouple Cov ntaub ntawv tawm tswv yim rau Standard Band Heater Aging Delay
Rhiav plua plav tsub zuj zuj, roj stain adhesion thiab yas volatile residue yog ib qho tseem ceeb ua rau kom cov laus ntawm cov txheej txheem band heaters. Ntau qhov kev ua haujlwm cua sov ua tsis tau zoo tsis yog los ntawm cov teeb meem tsis zoo, tab sis los ntawm qhov ntev - tsis muaj kev saib xyuas ib puag ncig. Cov ntaub ntawv saum npoo ua rau cov thermal tsis kam, ua rau cov cua sov hauv zos, ua kom cov txheej txheem rwb thaiv tsev carbonization, thiab thaum kawg ua rau cua sov attenuation thiab saib xyuas drift. Raws li kev saib xyuas cov ntaub ntawv txheeb xyuas, cov qauv kev tu ib puag ncig thiab kev saib xyuas tuaj yeem ncua kev laus ntawm cov khoom, thiab cov ntaub ntawv thermocouple cov lus tawm tswv yim tuaj yeem tsim cov kev tshawb fawb txog kev saib xyuas kom tsis txhob muaj kev tu ntau dhau lossis tsis saib xyuas.
Standard band heaters muaj qhib cov yam ntxwv, nrog cov plua plav thiab roj stains yooj yim adhering rau saum npoo thiab nkag mus rau hauv tshav kub dissipation qhov khoob. Ntev-Lub sij hawm sib sau ua ke thaiv cov kab hluav taws xob hluav taws xob, uas ua rau txo cov cua sov ua kom zoo dua qub thiab ua kom kub ua haujlwm sab hauv. Kev ua haujlwm siab -kub ua haujlwm nrawm nrawm mica rwb thaiv tsev laus thiab hlau hlau oxidation, ua rau txo cov cua sov ua haujlwm thiab ua haujlwm luv luv. Nyob rau hauv cov xwm txheej hnyav, cov cua sov hauv zos ua rau cov rwb thaiv tsev tawg, ua rau muaj hluav taws xob tiv thaiv kev nyab xeeb.
Qhov sib txawv ntawm cov ntaub ntawv sib txuas sib txuas nrog cov ntaub ntawv hloov pauv ntawm cov thermocouple. Thaum pib me ntsis plua plav tsub zuj zuj ua rau qeeb kub nce ntawm lub rhaub dej hauv qab lub zog ruaj khov. Qhov nruab nrab roj stain adhesion ua rau muaj qhov kub thiab txias hloov amplitude thiab tsis ruaj khov - lub xeev cov nqi. Thick carbonized residues ua rau kub tsis tu ncua overshoot thiab ncua kub poob. Cov kev hloov pauv tsis tu ncua no tuaj yeem siv los ua qhov ntsuas ntsuas ntau ntawm kev saib xyuas lub sijhawm.
Kev saib xyuas kev tshawb fawb lub voj voog tsim los ntawm cov ntaub ntawv thermocouple cov lus tawm tswv yim tuaj yeem sib npaug tus nqi tu thiab kev pab cuam lub neej. Kho - voj voog qhov muag tsis pom kev tu ua rau qhov tsis tsim nyog kaw thiab kev ua haujlwm pov tseg, thaum kev saib xyuas qeeb ua rau muaj kev laus zuj zus. Cov ntaub ntawv-raws li kev saib xyuas lub tswv yim ua rau kev tu thiab tu tsuas yog thaum qhov kub thiab txias nce mus txog qhov pib ceeb toom ntxov, paub txog - xav tau kev saib xyuas thiab ua kom tiav cov txiaj ntsig kev ua haujlwm.
Cov ntaub ntawv saib xyuas qhov sib piv txheeb xyuas qhov kev laus ncua sij hawm. Standard band heaters yam tsis muaj kev saib xyuas tus qauv muaj cua sov ua haujlwm ntawm 8.3% thiab cov thermocouple drift ntawm 1.5℃tom qab 4000 teev ntawm kev ua haujlwm. Cheebtsam txais cov ntaub ntawv tawm tswv yim kev saib xyuas lub tswv yim tsuas yog muaj qhov txo qis ntawm 2.4% thiab drift ntawm 0.4 degree, nrog rau kev pabcuam lub neej txuas ntxiv los ntawm ntau dua 40%. Cov nyhuv kho kom zoo dua qub yog qhov tseem ceeb heev.
Kev saib xyuas ib puag ncig raws li cov ntaub ntawv thermocouple sib piv yog qhov ua tau zoo thiab qis -tus nqi ua haujlwm kom zoo rau cov txheej txheem ntawm lub tshuab cua sov. Customized txij nkawm kev teeb tsa thiab kev tswj xyuas lub voj voog tuaj yeem tsim tau raws li kev cob qhia kev ua qias tuaj thiab kev siv ntau lawm kom ncua sij hawm tiv thaiv kev laus, tswj qhov kub thiab txias thiab txo qhov ntev - cov nqi siv khoom siv.
