Izinto eziluncedo kwiMveliso:

Namhlanje, i-O-Ring sesona sitywina sisetyenziswa kakhulu ngenxa yeendlela zayo zokuvelisa ezingabizi kakhulu kunye nokusebenziseka kwayo ngokulula.Sikunika uluhlu lwezixhobo ze-elastomeric kuzo zombini iinkqubo ezisemgangathweni nezikhethekileyo ezivumela i-O-Ring ukuba itywine yonke into engamanzi kunye negesi.

I-O-Ring egqibeleleyo yenjongo nganye

Ii-O-Rings zethu zombini zineendleko kwaye zisebenza kakhulu phantse kuyo yonke indawo.Kungakhathaliseki ukuba ufuna i-metric okanye i-intshi, i-O-Rings esemgangathweni okanye eyenziwe ngokwezifiso - nayiphi na isayizi ye-O-Ring ye-O-Ring iyafumaneka - kuquka i-O-Rings enkulu usebenzisa inkqubo yethu.I-rubber yethu ye-O-Rings yenziwe nge-EPDM, i-FKM, i-NBR, i-HNBR, kunye ne-FFKM yethu yobunini.Iimveliso ezikhethekileyo ngaphandle kweerubha ze-O-Rings ezifana ne-O-Rings kwizinto ze-PTFE kunye neentsimbi ze-O-Rings nazo ziyafumaneka.

O-Ring Seals

I-O-Rings isetyenziswa kwiinkalo ezahlukeneyo: mhlawumbi isetyenziswa njengezinto zokutywina okanye njengezinto ezinika amandlahydraulic slipper sealskunye nee wipers.Ke, i-O-Ring isetyenziswa ngokusisiseko kuyo yonke inkalo yeshishini kubandakanya i-aerospace, i-automotive okanye ubunjineli ngokubanzi.

Indlela yokukhetha ye-O-ring:

Icandelo le-O-ring yi-O-shaped (circular) ring seal ring, ngokuqhelekileyo ifakwe kwi-groove, isebenzisa umlinganiselo ofanelekileyo wokunyanzeliswa ukutywinwa kweoli, amanzi, umoya, igesi kunye nolunye ulwelo.Ukusetyenziswa kwe-O-ring i-static kunye nokuhamba kweentlobo ezimbini, ukuba ukusetyenziswa kweemeko azifanelekanga kuya kwenzeka ukuphuka, ukudumba, ukuqhekeka, njl njl. Ukuze kugcinwe ukusebenza kokutywinwa ixesha elide, kuyimfuneko ukuba ukhethe izinto ezifanelekileyo kunye nobukhulu beemveliso ze-O-ring.

I-O-ring itywina kukuthintela ukulahleka kolwelo kunye negesi, itywina iqulunqwe yi-O-ring kunye ne-groove yesinyithi, i-O-ring yenziwe ngezinto zerubha, kunye necandelo lesetyhula lendandatho, ngokuqhelekileyo yenziwe nge-groove yensimbi yokubeka. I-O-ring, i-Ogae ring seal yolwelo kunye negesi ibonakala ngokungavuzi.Le "ingenamthungo" inokufezekiswa ngeendlela ezininzi: Izitywina ze-O-ring ziyadityaniswa, zifakwe kwinkonkxa, zenziwe ngebrazed, zidityaniswe phezulu okanye zibekwe ngokuyinxenye okanye zibekwe ngokupheleleyo phakathi kwamacandelo amabini aqinileyo ezinto ezithambileyo.I-Rubber okanye ezinye izinto zeplastiki zinokuthi zithathwe njenge-viscous fluid kunye noxinzelelo oluphezulu, olungenakulinganiswa, kwaye lutywinwe ngenxa ye-O-ring's anti-elasticity yokunyanzeliswa kunye noxinzelelo lwenkqubo.

Izinto ezilungileyo ze-O-rings:

I-1, ingasetyenziswa kuluhlu olubanzi loxinzelelo, ubushushu kunye nezihlandlo zokucoca.
I-2, ukugcinwa lula, akukho lula ukonakalisa okanye ukutsala ngokuqinileyo.
I-3, akukho mzuzu obalulekileyo kwingxabano, ayiyi kubangela umonakalo wesakhiwo.
4. I-O-rings idla ngokufuna indawo encinci kunye nobunzima obulula.
I-5, kwiimeko ezininzi, i-O-rings ingaphinda isetyenziswe, eyinzuzo ukuba i-inelastic flat seals ezininzi ayinayo.
I-6, phantsi kweemeko ezichanekileyo zokusetyenziswa, ubomi bunokufikelela kwixesha lokuguga kwezinto ze-O-ring.
7, O-ring ukusilela ngokubanzi ngokuthe ngcembe, kwaye kulula ukugweba.'
I-8, nangona iimali ezahlukeneyo zokunyanzeliswa ziya kuvelisa iziphumo zokutywinwa ezahlukeneyo, kodwa ngenxa yokuba ivumela i-metal-to-metal contact, ayiyi kuba nefuthe kwi-O-ring.
I-9.Inexabiso eliphantsi kakhulu.

Izinto ze-O-ring

Xa ukhetha izinto ze-O-ring, izinto eziphambili ezifana ne-medium, i-pressure kunye neqondo lokushisa eliza kutywinwa kufuneka liqwalaselwe kwiinkalo ezininzi.Into enokuthi ifaneleke kakhulu kwi-steam, kodwa kwinkqubo yokupholisa amanzi iya kuba nemiphumo emibi ngenxa yotywala okanye i-antifreeze additives, into enokuthi ihambelane ne-oksijeni yamanzi kumaqondo aphantsi, kodwa ayifanelekanga ngokupheleleyo kumaqondo aphezulu.Ukukhethwa kwezinto ze-bezel kufuneka kusekwe kwisicelo esithile, ukutywinwa kwe-O-ring kubandakanya izinto ezininzi, ukhetho lokugqibela lwemathiriyeli kufuneka lube lolona khetho lubanzi.

Static itywina

Itywina elimileyo litywina apho imiphezulu emibini emeleneyo ingashukumiyo xa ithelekiswa enye kwenye.Izitywina eziqinileyo ziqhele ukufunyanwa kwindawo esezantsi yebholiti okanye i-rivet, kwindawo edibeneyo, okanye ezantsi kwepleyiti yokuvala okanye itephu.Kunokuthiwa i-O-ring yeyona nto ilungileyo yokutywina emile ukususela ekuphuhlisweni kwayo.Isizathu soku ikakhulu ngenxa yokuba i-O-ring "itywina lobudenge", nto leyo ayifuni ukongeza uxinzelelo xa i-original okanye i-over-itsalwe, kunye nemiba yempazamo yabantu ayinakungahoywa xa kuqinisekiswa ukusetyenziswa okuchanekileyo kwe-O- umsesane.I-O-rings ayifuni imithwalo emikhulu ukufezekisa i-zero-leak seal.

Isitywina esinamandla

Isitywina esinamandla sibhekisa kwintshukumo ebuyelanayo phakathi kwamalungu atywiniweyo, kwaye i-O-ring iyasuswa ngenxa yobukho bentshukumo.Kwi-cylinder ye-hydraulic, i-O-rings ingasetyenziselwa i-piston okanye i-piston rod dynamic seal, ifanelekile ngokukodwa i-piston okanye i-piston rod itywina eliguquguqukayo, lilungele ukubetha okufutshane, isilinda esincinci esincinci, i-O-rings ezingenakubalwa zisetyenziswe ngempumelelo kulwelo, i-fluid, kwaye nakwi-air compressed seal dynamic, kwiimeko ezininzi, i-O-rings isetyenziselwa i-stroke emide, i-cylinder enkulu yobubanzi, ukuba isetyenziswe ngokuchanekileyo, Ubomi be-O-ring bunokufana nobomi becandelo elitywiniweyo. , izinto ezichaphazela isitywina esiguquguqukayo zi-extrusion, ukuphindaphinda, ukugqithisa komhlaba kunye nobunzima bezinto eziphathekayo, kwinkqubo yoyilo, kubaluleke kakhulu ukuqwalasela ezi zinto.
