Thermowells rau Temperature Sensors
Taw qhia rau thermowells
Thermowells yog cov khoom tseem ceeb uas tiv thaiv cov thermocouples los ntawm ib puag ncig hnyav xws li kub, corrosion, thiab hnav. Xaiv lub thermowell tsim nyog tuaj yeem txhim kho kev ntseeg tau thiab kev lag luam ntawm kev ntsuas kub.

Cov txheej txheem sib txuas rau cov thermowells
Feem ntau muaj peb hom kev sib txuas ntawm thermowell: threaded, flanged thiab welded. Nws yog ib qho tseem ceeb heev uas yuav tsum xaiv qhov zoo thermowell raws li kev ua haujlwm.
Threaded Thermowell
Threaded thermowells yog tsim rau siv nyob rau hauv nruab nrab thiab qis-siab, tsis muaj zog corrosive ib puag ncig. Nws muaj qhov zoo ntawm kev saib xyuas yooj yim thiab tus nqi qis.
Peb threaded thermowells txais yuav ib qho tseem ceeb drilling txheej txheem, ua rau cov qauv kev nyab xeeb thiab txhim khu kev qha. NPT, BSPT, lossis Metric threads tuaj yeem siv rau cov txheej txheem kev sib txuas thiab ntsuas kev sib txuas, thiab sib xws nrog txhua hom thermocouples thiab ntsuas ntsuas kub.
Flanged Thermowell
Flanged thermowells yog tsim rau kub kub, siab siab, muaj zog corrosion los yog kev vibration ib puag ncig. Nws muaj qhov zoo ntawm kev sealing siab, durability, thiab kev saib xyuas yooj yim.
Peb flanged thermowell txais cov qauv vuam, cov yeeb nkab lub cev yog ua los ntawm tag nrho cov bar drilling, flange yog tsim raws li cov qauv kev lag luam (ANSI, DIN, JIS), thiab cov ntsuas kev sib txuas tuaj yeem xaiv los ntawm NPT, BSPT, lossis Metric xov.
Welded thermowell
Welded thermowells yog welded ncaj qha rau cov yeeb nkab, muab kev sib txuas zoo. Vim cov txheej txheem vuam, lawv tsuas yog siv qhov kev pabcuam tsis tsim nyog thiab corrosion tsis yog qhov teeb meem.
Peb cov welded thermowells yog machined siv ib qho txheej txheem drilling.
Styles ntawm Thermowell Sheath
●Ncaj
Nws yog qhov yooj yim rau kev tsim khoom, tsis tshua muaj nqi, thiab tsim nyog rau cov khoom siv sib xyaw ua ke.
●Tapered
Txoj kab uas hla hauv pem hauv ntej txhim kho cov lus teb ceev, thiab cov qauv tapered txhim kho lub peev xwm los tiv thaiv kev co thiab dej cuam tshuam. Nyob rau hauv cov xwm txheej uas muaj kev kub siab, siab txaus tus nqi, los yog nquag vibration, tag nrho cov drilling tsim thiab kev co kuj ntawm tapered casing yog ho zoo dua li cov hom ncaj.
●Stepped
Kev sib xyaw ua ke ntawm cov yam ntxwv ncaj thiab tapered rau ntxiv dag zog hauv qhov chaw tshwj xeeb.
Daim ntawv thov teb ntawm thermowells
⑴ Kev Saib Xyuas Txheej Txheem Kev Lag Luam
● Siv los saib xyuas qhov ntsuas kub ntawm cov xov xwm hauv cov raj xa dej thiab cov hlab ntsha hauv cov roj refining, petrochemical, fais fab, tshuaj, tshuaj thiab lwm yam lag luam los xyuas kom ruaj khov ntsuas nyob rau hauv qhov kub thiab txias, kub siab los yog corrosive ib puag ncig.
● Tiv thaiv thermocouples los ntawm kev puas tsuaj thiab tshuaj lom neeg yaig nyob rau hauv cov txheej txheem kub xws li steel smelting thiab ceramic ntau lawm.
● Tsim nyog rau kev lag luam ua zaub mov kom ua tau raws li cov qauv kev nyiam huv thiab tiv thaiv kev kis kab mob.
cov
⑵ Kev Tswj Hluav Taws Xob thiab Khoom Siv Hluav Taws Xob
● Ntsuas qhov kub ntawm cov kav dej kub thiab boilers. Piv txwv li, lub tes tsho kub kub thermocouple tshwj xeeb yog tsim los rau cov xwm txheej zoo li no thiab tuaj yeem tiv taus cov dej ntws siab.
● Saib xyuas qhov ntsuas kub ntawm cov roj turbines, boilers thiab lwm yam khoom siv hauv lub tshuab fais fab kom muaj kev nyab xeeb thiab ua haujlwm zoo.
cov
⑶ Tshawb nrhiav thiab Laboratory
● Muab cov txheej txheem ntsuas kub ruaj khov rau cov chaw soj nstuam los txhawb kev tswj xyuas cov xwm txheej hnyav hauv kev sim lub cev thiab tshuaj lom neeg.
