O-ring foob nta:
1) qhov zoo: qhov yooj yim qauv, me me ntim thiab qhov chaw cog kev ruaj ntseg; Cov tshuaj muaj kev sib fim rau tus kheej thiab tsis tas yuav tsum tau hloov kev hloov.Torque ruaj khov tuaj yeem ua tsis tau: Tsis muaj kev txaus siab thiab ua kom zoo;
2) disadvantages: 0) loj pib txhuam thaum siv rau compression thiab sealing; yog siv tsis zoo, nws yog yooj yim ua rau 0-puab nplhaib txiav, squeezing thiab rhuav tshem kev raug mob.Thaum rau lub tshuab torque, nws yog ib qho nyuaj kom tsis txhob to, yog li nws tsuas yog tswj tau qhov cov pa luam yeeb tsis ntau dua li qhov teev cia muaj nqis. Qhov qee zaum, cov looj rwb thaiv ntxiv thiab cov plua tshauv ploj feem ntau yuav tsum tau muaj nyob rau hauv.Thaum huab cua thiab dej thiab lwm yam sealing, tej zaum kuj yuav tsum tau nruab nrog lubricating accessories .
