Yuav ua li cas txiav txim qhov zoo ntawm thermocouple kuj

Thermocouple kuj
1. Lub tswv yim tseem ceeb ntawm thermocouple kuj
Thermocouple resistance yog hais txog qhov tsis kam ntawm cov khoom siv thermocouple, uas tuaj yeem nkag siab tias yog qhov cuam tshuam ntawm cov xaim thermocouple. Lub thermocouple yog ib qho khoom siv uas tuaj yeem hloov pauv qhov kub thiab txias rau hauv cov teeb liab hluav taws xob. Nws muaj ob lub xov hlau nrog cov khoom sib txawv, thiab kev sib cuag ntawm ob lub xov hlau ua rau muaj peev xwm ua kom sov. Los ntawm kev ntsuas qhov sib txawv ntawm qhov sib txawv, qhov kub thiab txias tuaj yeem ua tiav. Qhov zoo ntawm thermocouple tsis kam ncaj qha cuam tshuam qhov raug thiab ruaj khov ntawm nws qhov ntsuas.
2. Txoj kev kuaj xyuas cov thermocouple tsis kam
Txhawm rau txiav txim siab qhov tsis kam ntawm thermocouple, cov hauv qab no tuaj yeem siv:
Ntsuas qhov ntsuas tus nqi ntawm cov thermocouple siv lub tshuab ntsuas multimeter lossis ntsuas qhov ntsuas thiab sib piv nrog tus qauv tus nqi. Yog tias qhov ntsuas qhov ntsuas tsis zoo sib txawv ntawm tus qauv tus nqi, nws yuav qhia tau tias muaj teeb meem nrog cov thermocouple tsis kam.
Saib xyuas seb cov xov hlau thermocouple puas tawg, oxidized, lossis puas. Yog hais tias cov teeb meem saum toj no tau pom nyob rau hauv cov xov hlau thermocouple, nws yuav ua rau muaj kev hloov pauv ntawm cov nqi tiv thaiv thiab cuam tshuam rau qhov tseeb ntawm qhov ntsuas kub.
Ntsuas qhov muaj peev xwm sib txawv ntawm cov thermocouple thiab sib piv nws raws li qhov kub thiab txias qhov sib txawv nkhaus. Yog tias muaj qhov sib txawv tseem ceeb ntawm qhov ntsuas qhov sib txawv thiab tus qauv nkhaus, nws yuav qhia tau tias qhov ntsuas kub tsis kam hloov pauv.
3. Cov yam ntxwv cuam tshuam rau thermocouple kuj
Qhov zoo ntawm thermocouple tsis kam yog cuam tshuam los ntawm ntau yam, suav nrog:
Ob qhov kub thiab qis ambient kub tuaj yeem cuam tshuam rau qhov tsis kam ntawm thermocouples.
Thermocouples yog tsim los ntawm ob yam khoom sib txawv ntawm cov xov hlau, thiab kev xaiv ntawm cov ntaub ntawv xaim ncaj qha cuam tshuam rau kev ruaj ntseg thiab qhov tseeb ntawm lawv qhov tsis kam.
Ntev hlau ntev ntev yuav ua rau muaj kev hloov pauv ntawm cov nqi tiv thaiv.
Yog li ntawd, thaum siv cov thermocouples rau kev ntsuas kub, yuav tsum tau them nyiaj mloog mus rau qhov cuam tshuam ntawm cov yam ntxwv saum toj no, thiab kev ntsuas lub sijhawm thiab kev saib xyuas yuav tsum tau ua kom ntseeg tau qhov tseeb ntawm qhov ntsuas ntsuas.
4. Daim ntawv thov ntawm thermocouple kuj
Thermocouple kuj yog siv dav hauv kev ntsuas kub, suav nrog kev lag luam, kev tshawb fawb tshawb fawb, kev kho mob thiab lwm yam. Thermocouples tuaj yeem hloov cov cim ntsuas kub rau hauv cov cim hluav taws xob ntsuas, nrog rau qhov zoo xws li cov lus teb ceev ceev, kev ruaj ntseg thiab kev ntseeg tau, thiab tau dav siv hauv kev tswj qhov kub thiab txias, ntsuas kub thiab ntsuas kub.
Tsis tas li ntawd, cov thermocouple resistors kuj tuaj yeem siv ua ke nrog cov ntsuas kub, cov ntaub ntawv khaws cia, thiab lwm yam khoom siv los saib xyuas thiab tswj qhov kub thiab txias hauv lub sijhawm tiag tiag ntawm cov kab ntau lawm, chav kuaj, thiab lwm lub sijhawm.
5. Txoj kev loj hlob ntawm thermocouple kuj
Nrog rau kev nce qib ntawm thev naus laus zis thiab kev loj hlob tsis tu ncua ntawm kev thov, thermocouple resistors kuj tseem raug txhim kho thiab tsim kho tshiab hauv kev tsim thiab tsim khoom. Tam sim no, ntau cov thermocouple resistors tau maj mam siv rau hauv kev tsim khoom thiab kev sim kev tshawb fawb, nrog ntau dua, kev ntsuas ntau dua thiab muaj peev xwm tiv thaiv kev cuam tshuam zoo dua.
Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho txuas ntxiv ntawm thev naus laus zis, thermocouple kuj yuav txhim khu kev qha, muab cov kev daws teeb meem zoo dua rau kev ntsuas kub.
Nkag siab txog qhov zoo ntawm thermocouple kuj tseem ceeb heev rau kev ua kom qhov tseeb thiab ruaj khov ntawm qhov ntsuas kub. Los ntawm kev siv cov txheej txheem tshawb pom tsim nyog thiab kev saib xyuas raws sijhawm, kev siv ib txwm siv thiab kev ntseeg siab ntawm cov thermocouple resistors tuaj yeem ua kom ntseeg tau, muab kev txhawb nqa zoo rau kev ntsuas kub hauv ntau qhov chaw.
