Heater Dry-Hluav Tiv Thaiv Logic thiab Thermocouple Teeb Pom Kev Txuas Txoj Cai
Qhuav- kev tiv thaiv hluav taws kub ua haujlwm yog qhov tseem ceeb ntawm kev nyab xeeb rau cov tubular tso cua sov, tshwj xeeb tshaj yog cov kua immersion cua sov cov cuab yeej ua rau cov kua dej poob qis thiab nruab nrab poob. Feem ntau ntawm cov cua sov burnout teeb meem tshwm sim los ntawm kev ua tsis tiav qhuav-kev tiv thaiv kub hnyiab thiab cov lus teb qeeb. Muaj ntau pab pawg txhim kho tsuas yog nruab cov kua theem sensors yooj yim yam tsis tau teeb tsa qhov kub thiab txias sib txuas, tawm hauv qhov muag tsis pom kev hauv kev tiv thaiv kev nyab xeeb. Kev sib koom ua ke ntawm kev tiv thaiv kev tiv thaiv - qhuav- hlawv cov qauv tsim thiab cov ntsuas kub ntsuas kub ntsuas ntsuas ntsuas kev nyab xeeb dual cov txheej txheem thiab tshem tawm cov kev pheej hmoo tsis ua hauj lwm los ntawm kev kub hnyiab qhuav. Qhuav- hlawv kev puas tsuaj tshwm sim los ntawm kev sib sau ua ke sai sai yam tsis muaj kua nruab nrab kom ua kom sov. Thaum cov kua theem poob thiab nthuav tawm cov cua sov, qhov kub thiab txias nce siab hauv ob peb feeb. Cov thermal cuam tshuam loj heev ua rau muaj kev laus sai ntawm insulating magnesium oxide hmoov, overheating tsis ua hauj lwm nyob ntawm tej thiab ceev oxidation ntawm hlau raj plhaub. Siab- lub tshuab hluav taws xob muaj hluav taws xob ntsib qhov ziab qhuav ntau dua- hlawv hem, vim tias cov hluav taws xob loj dua tuaj yeem ua rau qhov kub thiab txias tuaj yeem ua rau lub qhov rais qhib qhov rooj rau kev tiv thaiv. Kev tiv thaiv kev daws teeb meem tsuas yog nyob ntawm cov kua theem sensors muaj qhov pom tseeb kev tsis zoo. Cov kua theem hloov yuav ua haujlwm tsis zoo vim qhov kev laus ntawm cov sensor, impurity adhesion ntawm kev sojntsuam thiab kev teeb tsa tsis raug. Hauv kev lag luam kev lag luam tiag tiag, kev ncua sij hawm xaim hluav taws xob thiab tsis tshua muaj kev cuam tshuam feem ntau ua rau kev tiv thaiv tsis ua haujlwm. Raws li kev tshawb nrhiav cov khoom siv ua kua tsis tuaj yeem hloov mus rau cov kev ua haujlwm tsis zoo, tsim kom muaj kev nyab xeeb zais cia rau siab - cov khoom siv hluav taws xob cua sov ua haujlwm tsis tu ncua. Thermocouple kub linkage tiv thaiv compensates rau qhov tsis txaus ntawm ib qho kua theem saib xyuas. Kev ziab qhuav ua rau muaj qhov txawv txav sai sai ntawm cov khoom siv hluav taws xob thiab sab hauv cov kab noj hniav. Thermocouple sensors ntes tam sim ntawd kub hloov pauv cov cim hauv lub sijhawm tiag tiag thiab xa cov ntaub ntawv los tswj cov chav nyob. Cov tswj hwm siv hluav taws xob tiv thaiv kev tiv thaiv raws li qhov ntsuas kub ua ntej thiab kev txiav txim siab ntawm cov cua sov, ua kom muaj kev ywj pheej ntawm qhov kub thiab txias{23}}raws li qhuav- hlawv kev tiv thaiv logic. Kev tiv thaiv kev sib txuas dual sib txuas siv cov cim ua kua theem thiab cov cim ntsuas kub ntawm qhov ntsuas kub tau ua tiav tag nrho - qhov ntsuas qhov tsis raug. Cov kua theem sensors txiav txim nruab nrab cov xwm txheej, thaum lub tshuab thermocouple txheeb xyuas qhov txawv txav ntawm thermal. Thaum ib lub teeb liab dhau ntawm thaj tsam nyab xeeb, lub kaw lus qhib kev tiv thaiv kev cuam tshuam tam sim ntawd. Qhov kev tsim qauv ob -txheej txheem no tshem tawm kev saib xyuas thaj chaw qhov muag tsis pom thiab txhim kho kev nyab xeeb rov ua dua rau cov tshuab cua sov ua haujlwm. Cov kws tshaj lij ua tau siab- lub tshuab hluav taws xob lub tshuab hluav taws xob sib xyaw ua kom zoo kom qhuav- hlawv kev tiv thaiv logic sib piv cov thermocouple teb ceev. Cov lus qhia ceev ceev tuaj yeem lav qhov kev sib txuas hluav taws xob ua ntej tsis tuaj yeem rov qab siab dua - qhov kub thiab txias tshwm sim. Txhim khu kev tiv thaiv kev ua tau zoo tiv thaiv kev poob siab ntawm lub tshuab hluav taws xob uas tsis tau npaj tseg thiab tsis tau npaj ntau lawm. Rau cov khoom siv cua sov tsis tu ncua thiab siab - lub zog ua kua hluav taws xob ua kom sov, dual- teeb liab qhuav- kev tiv thaiv hluav taws kub hnyiab yog qhov lav tsis tau rau kev ua haujlwm ntev - kev nyab xeeb thiab ruaj khov. Kev tiv thaiv parameter thresholds tuaj yeem hloov kho raws li cov yam ntxwv nruab nrab thiab cov qauv khoom siv.
