Hauv kev ntsuas kub ntawm kev lag luam, Teflon-coated corrosion-resistant thermocouples thiab caij nplooj ntoos hlav-loaded platinum kuj thermometers yog ob hom kub sensors. Lawv muaj qhov sib txawv tseem ceeb hauv kev tsim qauv, cov qauv kev ua haujlwm, cov yam ntxwv ntawm kev ua haujlwm, thiab cov xwm txheej ntawm daim ntawv thov. Cov kev sib piv hauv qab no los ntawm ntau qhov kev pom yuav qhia meej txog lawv qhov sib txawv tseem ceeb.
I. Qhov txawv ntawm cov qauv tsim thiab kev teeb tsa
1. Teflon-Coated Corrosion-Resistant Thermocouple
Cov yam ntxwv tseem ceeb ntawm Teflon-coated corrosion- tiv taus cov thermocouple nyob hauv nws cov Teflon txheej tiv thaiv thiab cov qauv hlau bimetallic. Nws feem ntau yog siv Teflon (polytetrafluoroethylene) sheath los qhwv ib lub raj tiv thaiv hlau, nrog ob txoj hlua hlau sib txawv (xws li npib tsib xee-chromium thiab npib tsib xee-silicon) welded ua ke sab hauv los ntsuas qhov kawg. Teflon sheath muaj kev ruaj ntseg zoo heev thiab tuaj yeem tiv thaiv corrosion los ntawm cov kua qaub uas muaj zog, muaj zog hauv paus, thiab cov kuab tshuaj organic, ua rau nws tsim nyog rau corrosive ib puag ncig hauv kev lag luam tshuaj thiab tshuaj. Nws txoj kev txhim kho feem ntau yog threaded kev twb kev txuas los yog flange kho, xyuas kom ze rau cov khoom nto los txhim kho kev ntsuas qhov tseeb thiab cov lus teb ceev. Piv txwv li, nyob rau hauv ib tug tshuaj reactor, lub Teflon sheath tiv thaiv lub thermocouple los ntawm corrosive media, thaum lub threaded kev twb kev txuas tso cai rau kom ceev installation.
