Sep 13, 2018

O-ring yog ib hom roj hmab foob nrog ib phab ntu. Vim tias nws qhov cross section yog O-puab, nws yog hu ua O-ring seal, kuj hu ua O-ring. Nws tau pib tshwm rau hauv xyoo pua thaum xyoo 19 thaum nws raug siv los ua ib qho kev sib khi rau lub tshuab ua haujlwm thooj txhij.


Vim tias nws cov nqi qis, yooj yim tsim, txhim khu kev ua haujlwm, thiab cov kev cai yooj yim, O-rings yog cov qauv kev tsim kho tshiab tshaj plaws rau sealing. O-rings raug cov kev kub ntxhov ntawm kaum ntawm megapascals (nplooj phaus). O-rings tuaj yeem siv rau hauv cov kev siv los ntawm kev siv los yog hauv cov ntawv thov dynamic uas muaj qhov sib luag ntawm cov cheebtsam, xws li cov ncej ntawm lub twj tso kua mis thiab lub piston ntawm tus hydraulic hydraulic.

Yog tias nws yog ib lub cim zoo li qub, nws muaj peev xwm raug pom tseeb raws li hauv qab no: hauv qab diameter ntawm qhov zawj / 1.04 (qhov elongation yog xam raws li 4%) = lub puab diam ntawm O-ring; qhov zawj qhov tob * 1.2 (qhov sib txwg sib piv yog xam li 20%) = O-ring wire diameter; xaiv qhov kev sib txuam ntawm qhov O-ring ntu yuav tawm, qhov dav dav dav feem ntau yog kwv yees li 1.3 npaug ntawm cov kab hlau. Ntawm cov hoob kawm, nws yog ib qhov tsim nyog los xav txog kev ua hauj lwm tej yam kev mob ntawm lub foob.
