Yuav Ua Li Cas Xaiv Lub Thermocouple rau Retrofitted Kub Runner System?

Retrofitting lub tshuab kub khiav nrog cov thermocouples tshiab yuav tsum tau ua tib zoo npaj kom muaj kev sib raug zoo thiab kev ua haujlwm. Thawj kauj ruam yog txhawm rau txheeb xyuas qhov system uas twb muaj lawm. Txiav txim siab tus thawj thermocouple hom (J, K, N), hom connector (DIN, mini-plug), lub sojntsuam txoj kab uas hla thiab ntev, thiab mounting style (xov, caij nplooj ntoos hlav-loaded). Txheeb xyuas tus maub los qhov tshwj xeeb kom paub meej tias hom thermocouple nws txhawb. Cov kauj ruam thib ob yog ntsuas lub qhov mounting. Siv calipers los ntsuas lub qhov taub, qhov tob, thiab xov loj. Yog hais tias lub qhov qub yog hnav, xav txog kev siv lub thermocouple nrog ib txoj kab uas hla me ntsis los yog threaded bushing los kho qhov haum. Qhov thib peb kauj ruam yog los ntsuam xyuas cov xaim uas twb muaj lawm. Yog hais tias tus thawj compensating cable tseem nyob rau hauv qhov chaw, xyuas nws tus mob. Yog hais tias nws yog qub los yog puas, hloov nws yog advisable. Siv ib lub cable nrog tib hom (piv txwv li, Hom K cable rau hom K thermocouple). Kauj ruam plaub yog xaiv qhov hloov. Siv cov kev ntsuas thiab kev qhia tshwj xeeb kom pom cov thermocouple sib haum. Ntau lub tuam txhab muab "cross-reference" cov lus qhia uas qhia lawv cov lej rau cov lej sib tw. Xwb, koj tuaj yeem muab tus lej qub rau tus neeg muag khoom, thiab lawv tuaj yeem pom zoo hloov. Cov kauj ruam thib tsib yog kuaj cov thermocouple tshiab ua ntej kev teeb tsa. Txheeb xyuas nws qhov kev tiv thaiv, rwb thaiv tsev, thiab calibration. Txuas nws mus rau tus maub los thiab xyuas kom meej tias tus maub los nyeem qhov tseeb qhov kub thiab txias ntawm chav tsev. Cov kauj ruam thib rau yog txhawm rau txhim kho cov thermocouple tshiab, ua raws li cov txheej txheem sib khi kom zoo. Siv cov tshuaj tiv thaiv- txeeb rau cov xov. Cov kauj ruam thib xya yog ua "kev sim pob" tom qab kev teeb tsa. Nce qhov teeb tsa los ntawm 5℃thiab saib cov lus teb. Lub thermocouple tshiab yuav tsum ua zoo ib yam li qub. Qhov thib yim kauj ruam yog los kho PID tsis yog tias tsim nyog. Lub thermocouple los ntawm lwm hom yuav muaj lub sijhawm teb txawv me ntsis, xav tau PID re-tune. Kauj ruam cuaj yog hloov kho cov ntaub ntawv. Sau cov thermocouple tshiab tus naj npawb, hom, thiab hnub teeb tsa hauv lub cav txij nkawm. Qhov no yog qhov tseem ceeb rau yav tom ntej traceability. Thaum retrofitting, nws yog qhov zoo tshaj plaws los hloov tag nrho cov thermocouples hauv pwm tib lub sijhawm, es tsis yog ib zaug, kom ntseeg tau tias muaj kev sib xws thiab txo tus naj npawb ntawm cov khoom sib txawv kom khaws cia. Los ntawm kev ua raws li cov kauj ruam no, retrofitting tuaj yeem ua tau zoo, kom ntseeg tau tias cov thermocouples tshiab tau sib xws, raug teeb tsa, thiab ua tau raws li qhov xav tau, ncua lub neej thiab txhim kho kev ua haujlwm ntawm cov laus kub khiav.
