Dab tsi yog Kev Lag Luam ntawm Thermocouple Failure hauv Siab -Volume Production?

Kev cuam tshuam kev lag luam ntawm lub thermocouple tsis ua haujlwm hauv siab - ntim ntau lawm feem ntau ntau dua li tus nqi ntawm lub sensor nws tus kheej, thiab qhov ntsuas qhov cuam tshuam no pab ua kom pom tseeb cov kev xaiv thiab kev saib xyuas zoo dua. Cia peb tshuaj xyuas daim ntawv thov ntim khoom ib txwm: 64- kab noj hniav pwm khiav 24/7 tsim lub kaus mom ntawm 5- lub voj voog thib ob. Ib qho thermocouple tsis ua haujlwm ntawm ib cheeb tsam tuaj yeem ua rau cov kab noj hniav ntawd tsim cov khoom tsis zoo. Hauv qhov xwm txheej phem tshaj - qhov xwm txheej, qhov tsis ua haujlwm tsis raug kuaj pom kom txog thaum kawg ntawm kev hloov pauv, los ntawm lub sijhawm ntau txhiab lub kaus mom yuav muaj qhov tsis zoo, txhua qhov yuav tsum tau txheeb xyuas thiab rov ua haujlwm dua. Txawm hais tias kuaj pom tam sim ntawd, cov pwm yuav tsum raug tso tseg, thaj chaw txias txias, hloov cov thermocouple, qhov kub thiab txias dua -stabilized, thiab tom qab ntawd cov khoom rov pib dua. Lub sijhawm downtime yuav yog 30-45 feeb. Ntawm qhov ntau lawm ntawm 11,520 qhov chaw hauv ib teev, 30-feeb nres txhais mus rau 5,760 qhov ploj. Ntawm tus nqi ntawm $ 0.10 ib feem, qhov ntawd yog 50 rau ob tus kws tshaj lij), tus nqi hloov pauv hloov pauv (200), thiab ib qho khoom seem tsim tawm thaum rov pib dua ($ 100), thiab tus nqi tag nrho tuaj yeem yooj yim tshaj $ 1,000 rau ib qho xwm txheej. Yog tias qhov ua tsis tiav no tshwm sim ib zaug ib lub lim tiam, tus nqi txhua xyoo yog tshaj $ 50,000. Tam sim no xav txog ntau dua - daim ntawv thov tus nqi, xws li cov khoom siv kho mob muaj nqis $10 txhua. Lub thermocouple tsis ua haujlwm ua rau lub sijhawm poob qis 30 feeb tuaj yeem raug nqi ntau txhiab daus las. Tshaj li cov nqi ncaj qha, muaj kev pheej hmoo ntawm kev xa cov khoom tsis zoo rau cov neeg siv khoom, ua rau rov qab los, rov ua haujlwm dua, tsis muaj kev ntseeg siab, thiab muaj peev xwm tswj tau cov teeb meem. Los ntawm qhov kev xav no, kev siv nyiaj ntxiv 100 rau qhov zoo tshaj plaws thermocouple uas kav ntev li ob zaug thiab txhim khu kev ntseeg ntau dua yog qhov kev lag luam zoo. Tus nqi tag nrho ntawm kev ua tswv cuab (TCO) qauv captures qhov no: TCO=tus nqi yuav khoom + nqi teeb tsa + (tus naj npawb ntawm kev ua tsis tiav × nqi ib qho tsis ua hauj lwm) + nqi ntawm cov teeb meem zoo. Feem ntau, TCO ntawm tus nqi them nqi thermocouple qis dua TCO ntawm lwm qhov pheej yig txawm tias tus nqi pib dua. Tsis tas li ntawd, ib qho kev tiv thaiv kev hloov pauv-hloov cov thermocouples ua ntej lawv ua tsis tiav-tawm cov nqi poob qis uas tsis tau npaj tseg. Tus nqi hloov pauv ib cheeb tsam ib xyoos yog kho thiab kwv yees tau. Thaum npaj koj lub tswv yim thermocouple, xam tus nqi ntawm ib qho tsis ua haujlwm ntawm koj qhov chaw thiab muab piv rau tus nqi sib txawv ntawm cov kev xaiv. Nyob rau hauv high-volume ntau lawm, tus hwm kev xaiv yuav luag yeej yeej. Qhov kev ntsuam xyuas kev lag luam no yog ib qho cuab yeej muaj zog los txhawb kev tswj hwm kom nqis peev hauv cov thermocouples zoo dua thiab muaj kev tiv thaiv ntau dua.
