O-ring (O-rings)yirabha yokutywina kunye necandelo lomnqamlezo ojikelezayo.Ngenxa yecandelo layo elinqamlezayo elimilise okwe-O, libizwa ngokuba yi-O-ring, ekwabizwa ngokuba yi-O-ring.Yaqala ukubonakala phakathi kwinkulungwane ye-19, xa yayisetyenziswa njengento yokutywina kwiisilinda ze-injini yomphunga.
O-amakhonkcozisetyenziselwa ikakhulu ukutywina okumileyo kunye nokutywinwa kwentshukumo ehambelanayo.Xa isetyenziselwa ukutywinwa kwentshukumo ejikelezayo, ilinganiselwe kwizixhobo zokutywina ezijikelezayo ezinesantya esisezantsi.I-O-ring ifakwe ngokubanzi kwi-groove ene-rectangular cross-section kwisangqa sangaphandle okanye isangqa sangaphakathi sokudlala indima yokutywina.Izitywina ze-O-ring zisadlala indima efanelekileyo ekutywinweni kunye nokufunxa ukothuka kwiindawo ezinjengokumelana ne-oyile, i-asidi kunye ne-alkali, i-abrasion, kunye nokukhukuliseka kweekhemikhali.
Iimpawu ze-O-ring:I-O-ring inomsebenzi obalaseleyo wokutywina kunye nobomi obude bokusebenza.Ubomi bokusebenza kwetywina loxinzelelo oluguquguqukayo ngamaxesha angama-5-10 aphezulu kuneemveliso eziqhelekileyo zokutywinwa kwerabha, ukuya kuthi ga kumaxesha amaninzi.Phantsi kweemeko ezithile, inokuba nobomi obufanayo ne-matrix yokutywina..Ukuxhatshazwa kwe-friction ye-O-ring encinci, kwaye i-friction eguquguqukayo kunye ne-static iyalingana, eyi-1/2-1/4 ye-friction ye-"0"-shaped rubber ring, enokuphelisa "ukukhasa" okwenzekayo. yentshukumo enesantya esisezantsi kunye noxinzelelo oluphantsi.I-O-ring ayinyangeki kakhulu, kwaye inomsebenzi wembuyekezo we-elastic ngokuzenzekelayo emva kokuba umphezulu wokutywina unxitywe.Amakhonkco e-O aneempawu ezilungileyo zokuzithambisa.Ingasetyenziswa njengetywina lokuthambisa ngaphandle kweoyile.I-O-ring inesakhiwo esilula kwaye kulula ukuyifaka.Uxinzelelo lwe-O-ring yokusebenza: 0-300MPa;isantya sokusebenza: ≤15m/s;ubushushu obusebenzayo: -55-250 degrees.I-O-ring medium medium: ioli ye-hydraulic, igesi, amanzi, udaka, ioli ekrwada, i-emulsion, i-water-glycol, i-asidi.
Izinto ezilungileyo ze-O-rings:Xa kuthelekiswa nolunye uhlobo lwamakhonkco okutywina, amakhonkco e-O anezi nzuzo zilandelayo: Ifanelekile kwiifom zokutywinwa ezahlukahlukeneyo: ukutywinwa kwe-static, ukutywinwa okuguquguqukayo, okufanelekileyo kwizinto ezahlukeneyo, ubungakanani kunye ne-grooves ziye zalinganisa, zitshintshana zinamandla, ezifanelekileyo kwiindlela ezahlukeneyo zokunyakaza. : intshukumo ejikelezayo, i-axial yokubuyisela intshukumo okanye intshukumo edibeneyo (efana ne-rotary reciprocating motion edityanisiweyo), ifanelekile kwiindidi ezahlukeneyo zokutywinwa kweendaba: ioli, amanzi, igesi, imidiya yekhemikhali okanye enye imidiya edibeneyo, ngokukhetha izinto ezifanelekileyo zerabha eziPhezulu kunye nokufanelekileyo. uyilo lwefomula lunokufikelela kwisiphumo esisebenzayo sokutywinwa kwi-oyile, amanzi, umoya, igesi kunye nemithombo yeendaba ezahlukeneyo zeekhemikhali.Uluhlu lweqondo lokushisa lubanzi (- 60 ℃ ~ + 220 ℃), kwaye uxinzelelo lunokufikelela kwi-1500Kg / cm2 ekusebenziseni okusisigxina (isetyenziswe kunye nendandatho yokuqinisa).Uyilo lulula, isakhiwo sihlangene, kwaye indibano kunye ne-disassembly ifanelekile.Isakhiwo se-cross-section ye-O-ring silula kakhulu, kwaye sinomsebenzi wokuzitywina, kwaye ukusebenza kokutywinwa kunokwethenjelwa.Ekubeni ubume be-O-ring ngokwayo kunye nenxalenye yofakelo ilula kakhulu kwaye isemgangathweni, kulula kakhulu ukuyifaka kunye nokubuyisela.Kukho iintlobo ezininzi zemathiriyeli: unokukhetha ngokwezilwelo ezahlukeneyo: kukho irabha ye-nitrile (NBR), irabha ye-fluorine (FKM), irabha yesilicone (VMQ), irabha ye-ethylene propylene (EPDM), irabha ye-neoprene (CR), irabha ye-butyl. ( BU), i-polytetrafluoroethylene (PTFE), irabha yendalo (NR), njl., enexabiso eliphantsi kunye nokumelana okuncinci okuguquguqukayo.

I-O-ring scope of application: I-O-rings ifanelekile ukufakwa kwizixhobo ezahlukeneyo zoomatshini, kwaye idlala indima yokutywinwa kwimeko emileyo okanye ehambayo phantsi kobushushu obuchaziweyo, uxinzelelo, kunye nemithombo eyahlukeneyo yamanzi kunye negesi.Iindidi ezahlukeneyo zamatywina zisetyenziswa ngokubanzi kwizixhobo zoomatshini, iinqanawa, iimoto, izixhobo ze-aerospace, oomatshini besinyithi, oomatshini beekhemikhali, oomatshini bobunjineli, oomatshini bokwakha, oomatshini bemigodi, oomatshini bepetroleum, oomatshini beplastiki, oomatshini bezolimo, kunye nezixhobo ezahlukeneyo kunye neemitha.isiqalelo.Amakhonkco e-O asetyenziselwa ukutywinwa okusisigxina kunye nokutywinwa kwentshukumo ehambelanayo.Xa isetyenziselwa ukutywinwa kwentshukumo ejikelezayo, ilinganiselwe kwizixhobo zokutywina ezijikelezayo ezinesantya esisezantsi.I-O-ring ifakwe ngokubanzi kwi-groove ene-rectangular cross-section kwisangqa sangaphandle okanye isangqa sangaphakathi sokudlala indima yokutywina.Izitywina ze-O-ring zisadlala indima efanelekileyo ekutywinweni kunye nokufunxa ukothuka kwiindawo ezinjengokumelana ne-oyile, i-asidi kunye ne-alkali, i-abrasion, kunye nokukhukuliseka kweekhemikhali.Ngoko ke, i-O-ring yeyona nto isetyenziswa kakhulu kwi-hydraulic kunye ne-pneumatic transmission systems.
