VIII. Yuav Ua Li Cas Xaiv Qhov Zoo Thermowell?
Cov duab ntawm lub thermowell feem ntau yog txiav txim siab los ntawm qhov nruab nrab ntawm qhov kub thiab txias, siab, ceev, khiav ceev, thiab qhov yuav tsum tau siv qhov ntev.ASME/ANSI PIC19.3 muab cov ncauj lus kom ntxaws specifications rau lub hom phiaj no. Thermowell lub zog tsom xam software tuaj yeem siv los txheeb xyuas seb tus qauv thermowell puas ua tau raws li cov txheej txheem.
Rau cov teb -ntsia thermowells, lawv lub zog yuav tsum raug xam. Lub ntsiab peb yam cuam tshuam rau lub zog thermowell yog:
Flow-induced vibrationCov kua uas dhau los ntawm lub thermowell tsim vortices ntawm ib zaus, hu ua vortex zaus, uas yog proportional to flow velocity.Yog hais tias qhov zaus no nyob ze los yog sib npaug rau lub ntuj zaus ntawm lub thermowell, resonance yuav tshwm sim, absorbing lub zog tseem ceeb thiab tsim kev puas tsuaj rau cov qauv ntawm thermowell. vortex zaus rau thermowell ntuj zaus yuav tsum tsawg dua 0.8.
Flow-Induced stressFluid flow imposes force on the thermowell, uas txawv nrog cov khiav ceev thiab ceev. Qhov kev ntxhov siab no tuaj yeem tau los ntawm kev suav.
Cov txheej txheem siab Qhov siab tshaj plaws zoo li qub uas lub thermowell tuaj yeem tiv taus tuaj yeem suav tau.
Kev sib txuas ntawm cov thermowell feem ntau suav nrog peb hom: threaded, flanged, thiab welded.
IX. Yuav Ua Li Cas Xaiv Qhov Zoo Tshaj Bimetallic Thermometer?
Rau kev teeb tsa kab rov tav: xaiv hom axial lossis universal hom bimetallic tus pas ntsuas kub.
Rau kev teeb tsa ntsug: xaiv hom radial lossis universal hom bimetallic tus pas ntsuas kub.
Rau inclined installation: xaiv axial, radial, lossis universal hom raws li qhov xav tau tiag tiag.
Yog hais tias lub tswb ceeb toom sab sauv thiab qis qis yuav tsum tau nyob ntawm qhov ntsuas ntsuas, siv lub ntsuas hluav taws xob tiv tauj bimetallic thermometer.
X. Qhov zoo thiab qhov tsis zoo ntawm Bimetallic Thermometers yog dab tsi?
Qhov zoo: Tus nqi qis, kev nyeem ntawv zoo.
Disadvantages: Qhov ntsuas qhov ntsuas qhov ntsuas qhov qis, qhov tseeb tsis tshua muaj.
Lawv feem ntau yog siv los ntsuas qhov ntsuas kub hauv zos thiab qhia cov cuab yeej.
