Yuav Ua Li Cas Hloov Cov Sheaths Txhim Kho Lub Sij Hawm ntawm Thermocouples hauv Vibratory Ib puag ncig?

Cov ntaub qhwv yooj yim tuaj yeem nqus tau thiab nqus cov vibrations. Nyob rau hauv ib puag ncig vibratory, kev txav tsis tu ncua thiab kev co tuaj yeem tso siab rau ntawm cov thermocouples. Flexible sheaths muaj peev xwm ntawm flex thiab dhau nrog kev vibrations, es tsis txhob tiv thaiv lawv. Qhov no ua rau kom txo qis cov nyhuv ntawm kev vibrations ntawm lub thermocouple nws tus kheej. Piv txwv li, hauv cov cuab yeej ua lag luam uas yuav muaj kev vibration tsis tu ncua, lub hau ntswj tuaj yeem txuag koj lub thermocouple los ntawm kev tawg ntawm txoj kev ntawm kev rov ua dua.
Lawv kuj tso cai rau ob peb daim ntawv pov thawj ntawm kev tawm suab nrog kev tawm tsam. Thermocouples nrog inflexible sheaths feem ntau yuav tawg los yog ua kom puas hauv qab uas tsis muaj kev vibration. Flexible sheaths, ntawm qhov tsis sib xws, tuaj yeem khoov thiab sib tw nrog kev tsis sib haum xeeb ntawm cov thermocouple. Qhov no txoj kev uas lawv muaj peev xwm mus fim mus rau ntxiv loj heev vibratory xwm txheej nrog tawm tsis ua hauj lwm.
Saj zawg zog sheaths tuaj yeem pom zoo rau qhov chaw txawv txav. Hauv ob peb qhov chaw vibratory, lub thermocouple kuj tseem xav tau txuas nrog hauv pem teb uas tsis tiaj tus lossis du. Lub bendy sheath tuaj yeem pwm nws tus kheej rau cov chaw no, nthuav tawm cov khaub ncaws ntau dua thiab ruaj khov ntxiv. Qhov no yuav txo tau lub caij nyoog ntawm cov thermocouple tuaj tsis ruaj los yog tawg vim kev txav.
Lawv muaj tsawg dua tej zaum yuav qaug zog thaum lub sij hawm. Rigid sheaths tuaj yeem nthuav dav cov kab nrib pleb thiab qaug zog dhau kev tshaj tawm mus rau kev vibrations. Flexible sheaths muaj kev tiv thaiv ntxiv rau kev qaug zog, vim tias lawv muaj peev xwm nqus tau thiab faib cov siab sib npaug. Qhov no tshwm sim nyob rau hauv ib tug ncua lifespan rau lub thermocouple.
Tsis tas li ntawd, bendy sheaths tuaj yeem ua haujlwm tsis tu ncua los ntawm cov khoom siv uas yuav ua tau ntev ntev thiab tiv thaiv kom tsis txhob tso thiab tsim kua muag. Cov tshuaj no tuaj yeem ntsib cov xwm txheej phem ntawm qhov chaw vibratory, zoo ib yam li kev txhim kho qhov ruaj khov ntawm thermocouple. Piv txwv li, ob peb bendy sheaths yog crafted los ntawm tshwj xeeb polymers los yog composites uas tej zaum yuav tsim los tiv thaiv ntau theem ntawm kev co thiab puas.
