Txawm li cas los xij, cov khoom siv roj hmab tuaj yeem ua tsis tau, ua rau muaj teeb meem rau kev lag luam lossis cov neeg siv khoom. Hauv tsab xov xwm no, peb yuav tham txog dab tsi tuaj yeem ua tsis ncaj ncees nrog cov roj hmab foob, thiab yuav ua li cas zam lossis daws cov teeb meem no.
Hom Roj Hmab Seals
Ua ntej peb dhia mus rau hauv cov teeb meem cuam tshuam nrog cov roj hmab ntsaws ruaj ruaj, nws yog ib qho tseem ceeb kom nkag siab txog ntau hom roj hmab foob muaj nyob hauv khw. Ob hom tseem ceeb yog:
1. O-Rings: O-rings yog cov ntsaws ruaj ruaj nrog ib puag ncig hla ntu. Lawv feem ntau siv nyob rau hauv hydraulic thiab pneumatic systems, thiab raws li zoo li qub seals nyob rau hauv lub tshuab qhov chaw.
2. Gaskets: Gaskets yog cov ntsaws ruaj ruaj uas feem ntau yog siv rau hauv cov ntaub ntawv zoo li qub, xws li tsheb cav ntsaws ruaj ruaj thiab HVAC duct ua haujlwm.
Muaj ntau ntau hom roj hmab ntsaws ruaj ruaj muaj, nrog rau daim di ncauj, V-rings, thiab hauv qab. Txawm li cas los xij, O-rings thiab gaskets feem ntau yog siv.
Teeb meem nrog Rubber Seals
Txawm hais tias cov roj hmab foob feem ntau txhim khu kev qha, muaj qee qhov teeb meem uas tuaj yeem tshwm sim.
1. Cov dej xau: Ib qho teeb meem feem ntau cuam tshuam nrog cov roj hmab ntsaws ruaj ruaj yog cov xau. Yog hais tias lub foob tsis ua kom raug foob rau saum npoo nws yog tsim los tiv thaiv, nws tuaj yeem ua rau xau. Qhov no yog qhov teeb meem tshwj xeeb hauv kev lag luam uas qhov dej xau tuaj yeem ua rau muaj kev puas tsuaj loj, xws li hauv cov tshuab hydraulic lossis hauv cov nroj tsuag tshuaj.
2. Compression set: Compression set tshwm sim thaum lub roj hmab foob poob nws lub peev xwm rov qab mus rau nws qhov qub zoo tom qab compressed. Qhov no tuaj yeem ua rau lub foob poob nws lub peev xwm los kaw kom zoo raws sijhawm.
3. Hnav thiab tsim kua muag: Cov roj hmab ntsaws ruaj ruaj yuav tsum hnav thiab tsim kua muag thaum lub sijhawm, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas muaj kev sib txhuam ntau heev. Qhov no tuaj yeem ua rau lub foob ua haujlwm tsis zoo nyob rau lub sijhawm.
4. Chemical degradation: Roj hmab seals tuaj yeem raug tshuaj lom neeg degradation yog tias lawv tau ntsib nrog qee yam tshuaj. Qhov no tuaj yeem ua rau lub foob ua rau nkig thiab ua rau tawg.
5. Qhov kub thiab txias: Cov roj hmab ntsaws ruaj ruaj tuaj yeem poob rau qhov kub siab heev. Yog tias lub foob raug rau qhov kub siab tshaj lossis qis dua nws qhov kev ua haujlwm tau pom zoo, nws tuaj yeem ua nkig thiab plam nws lub peev xwm los kaw kom zoo.
