Koj paub ntau npaum li cas txog sealing washers?

Sealing tshuab ntxhua khaub ncaws yog ib hom khoom seem siv rau kev sib khi tshuab, khoom siv, thiab cov kav dej nyob qhov twg muaj cov kua dej. Nws yog ib yam khoom siv rau sealing ob sab hauv thiab sab nraud. Sealing washers yog ua los ntawm cov hlau los yog cov hlau tsis yog hlau zoo li cov ntaub ntawv los ntawm kev txiav, stamping, lossis txiav cov txheej txheem, siv rau kev sib khi sib txuas ntawm cov kav dej thiab nruab nrab ntawm cov khoom siv tshuab. Raws li cov khoom siv, nws tuaj yeem muab faib ua hlau sealing washers thiab non-metallic sealing washers. Hlau washers muaj xws li tooj liab washers,stainless hlau washers, hlau ntxhua khaub ncaws, txhuas ntxhua khaub ncaws, thiab lwm yam. Tsis yog xim hlau muaj xws li asbestos washers, non asbestos washers, paper washers,roj hmab washers, lwm.

Cov ntsiab lus hauv qab no yuav tsum tau sau tseg:

(1) Kub
Hauv cov txheej txheem xaiv feem ntau, qhov ntsuas kub ntawm cov kua dej yog qhov kev txiav txim siab tseem ceeb. Qhov no yuav nqaim qhov kev xaiv sai sai, tshwj xeeb tshaj yog los ntawm 200 ° F (95 ℃) txog 1000 ° F (540 ℃). Thaum lub kaw lus ua haujlwm kub ncav cuag qhov siab tshaj plaws kev ua haujlwm kub tsis tu ncua ntawm cov khoom siv ntxhua khaub ncaws, yuav tsum xaiv cov khoom siv ntau dua. Qhov no kuj yuav tsum yog cov ntaub ntawv nyob rau hauv tej yam uas tsis tshua muaj kub.

 

(2) Kev thov
Qhov tseem ceeb tshaj plaws hauv daim ntawv thov yog hom flange thiab covbolts siv. Qhov loj, qhov ntau, thiab qib ntawm bolts hauv daim ntawv thov txiav txim siab qhov ua haujlwm tau zoo. Qhov chaw zoo ntawm compression yog xam raws li qhov sib cuag loj ntawm lub tshuab ntxhua khaub ncaws. Lub tshuab ntxhua khaub ncaws zoo tuaj yeem tau txais los ntawm kev thauj khoom ntawm lub ntsia liaj qhov rooj thiab qhov sib cuag ntawm lub tshuab ntxhua khaub ncaws. Yog tsis muaj qhov ntsuas no, nws yuav tsis yooj yim sua kom xaiv qhov zoo tshaj plaws ntawm ntau cov ntaub ntawv.

(3) Media
Muaj ntau txhiab cov kua dej hauv nruab nrab, thiab corrosiveness, oxidation, thiab permeability ntawm txhua cov kua sib txawv heev. Cov khoom siv yuav tsum raug xaiv raws li cov yam ntxwv no. Tsis tas li ntawd, kev tu lub cev kuj yuav tsum tau txiav txim siab los tiv thaiv kev yaig ntawm lub tshuab ntxhua khaub ncaws los ntawm kev siv tshuaj ntxuav.

(4) Siab
Txhua yam ntawm lub tshuab ntxhua khaub ncaws muaj nws qhov siab tshaj plaws siab tshaj plaws, thiab lub siab ua haujlwm ntawm lub tshuab ntxhua khaub ncaws tsis muaj zog nrog qhov nce ntawm cov khoom tuab. Lub thinner cov khoom, qhov ntau dua lub siab bearing muaj peev xwm. Kev xaiv yuav tsum yog nyob ntawm qhov siab ntawm cov kua hauv qhov system. Yog tias lub siab feem ntau hloov pauv hnyav, nws yuav tsum nkag siab txog cov ncauj lus kom ntxaws txhawm rau txiav txim siab xaiv.

(5) PT tus nqi
Tus nqi hu ua PT yog qhov khoom ntawm qhov siab (P) thiab kub (T). Lub siab tsis kam ntawm txhualub tshuab ntxhua khaub ncaws cov khoom sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias thiab yuav tsum tau muab xam kom tiav. Feem ntau, cov chaw tsim khoom ntawm gaskets yuav muab qhov siab tshaj plaws PT tus nqi ntawm cov khoom.
