I-O-ring (O-rings)iyindandatho yokuvala injoloba enesigaba esiphambanayo esiyindilinga.Ngenxa yesiphambano esimise okwe-O, ibizwa ngokuthi i-O-ring, ebizwa nangokuthi i-O-ring.Yaqala ukubonakala phakathi nekhulu le-19, lapho isetshenziswa njengento yokuvala amasilinda enjini yesitimu.
O-izindandathozisetshenziselwa kakhulu ukubekwa uphawu okumile kanye nokubeka uphawu okuhambisanayo kokunyakaza.Uma isetshenziselwa ukuvala ukunyakaza okujikelezayo, ikhawulelwe kumishini yokuvala ejikelezayo enesivinini esiphansi.I-O-ring ngokuvamile ifakwa ku-groove enesiphambano esingunxande esiyingini sangaphandle noma indingilizi engaphakathi ukuze idlale indima yokuvala.Izigxivizo ze-O-ring zisadlala indima enhle ekuvaleni nasekumunceni ukushaqeka ezindaweni ezifana nokumelana nowoyela, i-asidi ne-alkali, ukuhuzuka, nokuguguleka kwamakhemikhali.
Izici ze-O-ring:I-O-ring inokusebenza okuhle kakhulu kokuvala nempilo ende yokusebenza.Impilo yokusebenza ye-dynamic pressure seal iphakeme izikhathi ezi-5-10 kunemikhiqizo evamile yokuvala injoloba, kuze kube izikhathi eziningi.Ngaphansi kwezimo ezithile, ingaba nempilo efanayo ne-matrix yokuvala uphawu..Ukumelana nokungqubuzana kwendandatho ye-O kuncane, futhi ukungqubuzana okuguquguqukayo nokumile kuyalingana, okuyi-1/2-1/4 yokungqubuzana kwendandatho yerabha emise okwe-0, engaqeda into "ekhasayo". yokuhamba ngesivinini esiphansi kanye nomfutho ophansi.I-O-ring imelana kakhulu nokugqokwa, futhi inomsebenzi wokunxephezela okuzenzakalelayo okunwebekayo ngemva kokugqokwa kwendawo yokuvala.Ama-O-ring anezinto ezinhle zokuzithambisa.Ingasetshenziswa njenge-lubrication seal engenawo uwoyela.I-O-ring inesakhiwo esilula futhi kulula ukuyifaka.Ingcindezi yokusebenza ye-O-ring: 0-300MPa;isivinini sokusebenza: ≤15m/s;izinga lokushisa lokusebenza: -55-250 degrees.I-O-ring medium esebenzayo: uwoyela we-hydraulic, igesi, amanzi, udaka, uwoyela ongahluziwe, i-emulsion, amanzi-glycol, i-asidi.
Izinzuzo ze-O-rings:Uma kuqhathaniswa nezinye izinhlobo zamasongo okuvalwa, ama-O-ring anezinzuzo ezilandelayo: Ifanele amafomu okufaka uphawu ahlukahlukene: ukubekwa uphawu okumile, ukubekwa uphawu okuguquguqukayo, okulungele izinto ezihlukahlukene, osayizi kanye nemisele kumisiwe, kushintsheka ku-Strong, kulungele izinhlobo ezahlukene zokunyakaza. : ukunyakaza okujikelezayo, ukunyakaza okuphindaphindayo kwe-axial noma ukunyakaza okuhlanganisiwe (njengokunyakaza okuhambisanayo okujikelezayo okuhlangene), kulungele izinhlobonhlobo zemidiya yokuvala ehlukene: uwoyela, amanzi, igesi, imidiya yamakhemikhali noma enye imidiya exubile, ngokukhetha impahla yerabha Ethuthukisiwe efanele kanye efanele ukwakheka kwefomula kungafinyelela umphumela wokuvala osebenzayo kuwoyela, amanzi, umoya, igesi kanye nemidiya ehlukahlukene yamakhemikhali.Izinga lokushisa libanzi (- 60 ℃ ~ + 220 ℃), futhi ingcindezi ingafinyelela ku-1500Kg/cm2 ekusetshenzisweni okungaguquki (isetshenziswa kanye nendandatho yokuqinisa).Idizayini ilula, isakhiwo sihlangene, futhi ukuhlanganisa nokuhlakazeka kulula.Isakhiwo se-cross-section se-O-ring silula kakhulu, futhi sinomsebenzi wokuzivala, futhi ukusebenza kokuvala kunokwethenjelwa.Njengoba ukwakheka kwe-O-ring ngokwayo kanye nengxenye yokufaka kulula kakhulu futhi kulinganiselwe, kulula kakhulu ukuyifaka nokufaka esikhundleni.Kunezinhlobo eziningi zezinto zokwakha: ungakhetha ngokuvumelana noketshezi oluhlukene: kukhona irabha ye-nitrile (NBR), irabha ye-fluorine (FKM), irabha ye-silicone (VMQ), irabha ye-ethylene propylene (EPDM), irabha ye-neoprene (CR), irabha ye-butyl. (BU), i-polytetrafluoroethylene (PTFE), irabha yemvelo (NR), njll., enezindleko eziphansi kanye nokumelana nokungqubuzana okuncane okushukumisayo.

I-O-ring scope of application: Ama-O-ring afanele ukufakwa kumishini ehlukahlukene, futhi adlala indima yokuvala esimweni esimile noma esinyakazayo ngaphansi kwezinga lokushisa elicacisiwe, ingcindezi, kanye nemidiya ehlukene yoketshezi negesi.Izinhlobo ezahlukahlukene zezimpawu zisetshenziswa kakhulu kumathuluzi omshini, imikhumbi, izimoto, imishini ye-aerospace, imishini yensimbi, imishini yamakhemikhali, imishini yobunjiniyela, imishini yokwakha, imishini yezimayini, imishini ye-petroleum, imishini yepulasitiki, imishini yezolimo, nezinsimbi ezahlukahlukene namamitha.isici.Ama-O-ring asetshenziselwa kakhulu ukuvala uphawu okumile kanye nokuvala uphawu okuhambisanayo.Uma isetshenziselwa ukuvala ukunyakaza okujikelezayo, ikhawulelwe kumishini yokuvala ejikelezayo enesivinini esiphansi.I-O-ring ngokuvamile ifakwa ku-groove enesiphambano esingunxande esiyingini sangaphandle noma indingilizi engaphakathi ukuze idlale indima yokuvala.Izigxivizo ze-O-ring zisadlala indima enhle ekuvaleni nasekumunceni ukushaqeka ezindaweni ezifana nokumelana nowoyela, i-asidi ne-alkali, ukuhuzuka, nokuguguleka kwamakhemikhali.Ngakho-ke, i-O-ring iwuphawu olusetshenziswa kakhulu kuma-hydraulic kanye ne-pneumatic transmission systems.
