Ts'ebetso ea likhokahano bakeng sa li-thermowells
Hangata ho na le mefuta e meraro ea likhokahano tsa thermowell: tse khoele, tse flanged le tse cheselitsoeng. Ho bohlokoa haholo ho khetha thermowell e nepahetseng ho latela maemo a ho sebetsa.
Thermowell e kentsoeng
Li-thermowell tse nang le likhoele li loketse ho sebelisoa maemong a mahareng le a khatello e tlase, a sa senyeheng haholo. E na le melemo ea tlhokomelo e bonolo le litšenyehelo tse tlaase.
Li-thermowell tsa rona tse nang le likhoele li sebelisa mokhoa oa bohlokoa oa ho cheka, ho etsa hore sebopeho se bolokehe le ho tšepahala. Likhoele tsa NPT, BSPT, kapa Metric li ka sebelisoa bakeng sa likhokahano tsa ts'ebetso le likhokahano tsa lisebelisoa, 'me li tsamaisana le mefuta eohle ea li-thermocouples le lisebelisoa tsa ho lekanya mocheso.
Flanged Thermowell
Li-thermowell tse nang le flanged li loketse mocheso o phahameng, khatello e phahameng, kutu e matla kapa maemo a sisinyehang. E na le melemo ea ho tiisa haholo, ho tšoarella nako e telele, le tlhokomelo e bonolo.
Thermowell ea rona e nang le flanged e nka sebopeho sa welding, 'mele oa liphaephe o entsoe ka ho phunya bar kaofela, flange e hlahisoa ho latela maemo a indasteri (ANSI, DIN, JIS), le khokahanyo ea lisebelisoa e ka khethoa ho tloha NPT, BSPT, kapa Metric thread.
Thermowell e cheselitsoeng
Li-thermowell tse cheselitsoeng li cheselitsoe ka kotloloho ho phala, li fana ka khokahano ea boleng bo holimo. Ka lebaka la ts'ebetso ea li-welding, li sebelisoa feela moo ho sa hlokahaleng ho sebetsa le ho senya ha se taba.
Li-thermowell tsa rona tse cheselitsoeng li entsoe ka mochini ho sebelisa mokhoa o le mong oa ho cheka.
Mekhoa ea Thermowell Sheath
●Setereiti
E bonolo ho e etsa, e theko e tlaase, 'me e loketse libaka tse tloaelehileng tsa ho kenya.
●Tapered
Bophara ba ka pele bo tšesaane bo ntlafatsa lebelo la karabelo, 'me moralo o tapered o ntlafatsa bokhoni ba ho hanela ho thothomela le tšusumetso ea mokelikeli. Maemong a nang le khatello e phahameng, lebelo la phallo e phahameng, kapa ho sisinyeha khafetsa, moralo o akaretsang oa ho cheka le ho hanyetsa ho sisinyeha ha casing e tapered e ntle haholo ho feta ea mofuta o otlolohileng.
●E hata
Motsoako oa likarolo tse otlolohileng le tse tapered bakeng sa matla a eketsehileng libakeng tse itseng.
Libaka tsa ts'ebeliso ea li-thermowells
⑴ Tlhokomelo ea Ts'ebetso ea Liindasteri
● E sebelisetsoa ho shebella mocheso oa mecha ea litaba ka liphaephe le likepe tse itšoarang ka har'a ho hloekisa oli, petrochemical, matla, lik'hemik'hale, meriana le liindasteri tse ling ho etsa bonnete ba hore tekanyo e tsitsitseng mocheso o phahameng, khatello e phahameng kapa libaka tse senyang.
● Sireletsa thermocouple hore e se ke ea senyeha le ho khoholeha ha lik'hemik'hale maemong a mocheso o phahameng joalo ka ho qhibilihisa tšepe le tlhahiso ea ceramic.
● E loketse indasteri ea ho lokisa lijo ho finyella litekanyetso tsa bohloeki le ho thibela tšilafalo ea mecha ea litaba.

⑵ Taolo ea Matla le Thepa
● Lekanya mocheso oa liphaephe tsa mouoane o chesang le liboiler. Ka mohlala, thermocouple ea sleeve ea mocheso e etselitsoe ka ho khetheha bakeng sa maemo a joalo 'me e khona ho mamella mocheso o phahameng oa mouoane.
● Lekola mocheso o sebetsang oa li-turbine tsa khase, li-boilers le lisebelisoa tse ling tsamaisong ea matla ho netefatsa polokeho le katleho.

⑶ Lipatlisiso le Laboratori
● Fana ka mekhoa e tsitsitseng ea ho lekanya mocheso bakeng sa lilaboratori ho tšehetsa taolo e nepahetseng ea maemo a feteletseng litekong tsa 'mele le tsa lik'hemik'hale.
