MayelanaPTFE o-amasongokanye nomlando we-PTFE olayishwe entwasahlobo njengokulandelayo:
Kuzinhlelo zokusebenza eziguquguqukayo ezidinga ukubekwa uphawu ngesivinini esiphansi ukuya kwezimaphakathi nezingcindezi, onjiniyela abaklami bafaka esikhundleni se-elastomeric engasebenzi kahle.O-izindandathongezimpawu ze-PTFE “C-ring” ezilayishwe entwasahlobo.
Uma ama-O-rings nezinye izindlela zokuvala ezivamile zingasebenzi, onjiniyela bedivayisi yokuxilonga neyokulethwa kwezidakamizwa bathatha indlela entsha, engabizi kakhulu yokuthuthukisa ukusebenza kwemiklamo yabo yemishini ekhona: PTFE “C-Ring” spring seals.
Ama-C-seal aqale aklanyelwe amathuluzi okuxilonga kusetshenziswa i-piston ephindaphinda amafidi angu-5 ngomzuzu esebenza endaweni yokugeza yamanzi cishe engu-100°F.Izimo zokusebenza zimnene, kodwa ngokubekezelelana okukhulu.Umklamo wangempela wawudinga i-elastomeric o-ring ukuze ivale i-piston, kodwa i-o-ring ayikwazanga ukugcina uphawu oluhlala njalo, okwenza idivayisi ivuze.
Ngemva kokwakhiwa kwe-prototype, onjiniyela baqala ukufuna ezinye izindlela.Ama-U-rings noma ama-lip seal ajwayelekile, avame ukusetshenziswa kuma-pistons, awafaneleki ngenxa yokubekezelelana okukhulu kwe-radial.Akunakwenzeka futhi ukuzifaka kumarecesi agcwele.Ukufakwa kudinga ukwelula kakhulu, okuholela ekuguquleni nasekuhlulekeni ngaphambi kwesikhathi kophawu.
Ngo-2006, i-NINGBO BODI SEALS .,LTD yaqhamuka nesixazululo sokuhlola: isiphethu se-helical ekheniwe esongwe nge-PTFE C-ring.Ukuphrinta kusebenza ngendlela elindelekile.Ihlanganisa izici eziphansi zokungqubuzana kwe-PTFE nejiyomethri yebhuthi ehlelekile, “i-C-Rings” ihlinzeka ngophawu oluthembekile, oluhlala njalo futhi abushelelezi futhi athule kune-O-Rings.Ukwengeza, ama-C-rings afanele ama-o-rings agcwele isigaba, ngokuvamile anganconywa ngezinto ze-inelastic.Ngakho-ke, i-C-ring ingafakwa ngaphandle kokushintsha umklamo wemishini yokuqala noma ukusebenzisa noma yimaphi amathuluzi akhethekile.
I-C-seal yokuqala yayineminyaka emibili ubudala.Ukusetshenziswa kwama-C-rings kuthuthukisa ukusebenza komkhiqizo futhi kwelula impilo yemishini ngokunciphisa isikhathi sokuphumula kanye nezindleko zokuyilungisa.
Imishini yokuthwebula yezokwelapha, amaphampu e-insulin, ama-ventilator, kanye nemishini yokulethwa kwezidakamizwa ngokuvamile isebenzisa ama-O-rings ukuvala izikhala ezimfushane ze-axial.Kodwa lapho amandla okuchezuka okwedlulele kwe-radial edingeka, ama-O-ring awakwazi ukunxephezela lokhu, ngokuvamile okuholela ekugugekeni, ekuguquguqukeni unomphela, kanye nokuvuza.Naphezu kwalokhu kushiyeka, onjiniyela bayaqhubeka nokusebenzisa ama-o-rings ngoba ezinye izixazululo (isb. Izinkomishi ze-U, izindebe zomlomo) azikwazi ukuhlangabezana nezimfuneko zokuchezuka kwe-radial futhi ngokuvamile zidinga isikhala se-axial esiningi kune-o-rings.
I-C-ring ihlukile ngokuthi ingangena endaweni encane ye-axial ngokuvamile ehlinzekwa i-O-ring, kuyilapho izimpawu ezijwayelekile zingakwazi.Ngaphezu kwalokho, ama-C-rings angenziwa ngokwezifiso ngokugcwele ukuze ahambisane nezidingo zohlelo lokusebenza.Ingalungiselelwa ngodebe oluncane oluncane futhi oluguquguqukayo lwezinhlelo zokusebenza ze-cryogenic noma udebe oluqinile lwezinhlelo zokusebenza eziguquguqukayo lapho uphawu ludinga ukumelana nokugqoka okwengeziwe.
Ngenxa yokuthi ama-C-ring avumela kokubili ukunyakaza okujikelezayo nokuphindaphindayo, ayisixazululo esiguquguqukayo sohlu olubanzi lwemikhiqizo edinga ukuvala uphawu ngesivinini esiphansi ukuya esimaphakathi, okuhlanganisa amarobhothi ezokwelapha, izisetshenziswa zezokwelapha eziphathwayo, nezixhumi ze-probe/tubing.Ama-C-rings avumela ukubekezelelana kwama-radial amakhulu ngokungavamile—okungenani okukhulu ngokuphindwe kahlanu kunezimpawu ezijwayelekile zesigaba esiphambanayo.Ububanzi bokubekezelelana buncike ekucindezelweni kwendawo, uhlobo lwe-medium kanye nezimo zokwelashwa ezingaphezulu.Ama-C-rings nawo asebenza kahle ekusetshenzisweni okumile lapho izingxenye zidinga ukuvikelwa ekungcoleni kwemvelo.
Ngokususa izinto ze-PTFE ekwakhiweni kwebhuthi yokuqala ye-C-ring, onjiniyela bakwazile ukukhulisa ukunwebeka nokuvumelana nezimo.Ngenxa yalokho, ama-C-rings afakazele ukuthi anwebeka futhi aguquguqukayo kunalokho obekulindelwe ekuqaleni, okuwenza afanelekele izinhlelo zokusebenza ezingezona eziyindilinga.Ama-C-rings asetshenziswe kumaphampu okulethwa kwezidakamizwa anama-oval pistons.Ngenxa yokuthi udebe oluvala uphawu lungenziwa nge-PTFE emsulwa noma i-PTFE egcwele, indandatho ye-C iwuphawu olushintshashintshashintshashintshashintshashintsha kakhulu oluhambisana nensimbi nezingxenye zepulasitiki.
Ama-C-rings, ekuqaleni aklanyelwe ukusetshenziswa ngamathuluzi okuxilonga asekelwe emanzini, ahlanganisa iziphethu ze-helical ezinejakhethi ye-PTFE.Kodwa ama-C-rings nawo angenziwa kusetshenziswa i-helical band springs njengama-activator.Ngokufaka esikhundleni semithombo ye-helical ene-helical band springs, ama-C-rings anganikeza ingcindezi ephezulu kakhulu yokuvala uphawu, elungele izinhlelo zokusebenza ze-cryogenic noma ezimile.
I-Bal Seal Engineering ibiza i-C-ring yayo ngokuthi “uphawu oluphelele lomhlaba ongaphelele” ngenxa yekhono layo lokuhlinzeka ngempilo enwetshiwe yesevisi ezindaweni lapho izikhala, ukuphela komhlaba nezinye izici zedizayini zihluka kakhulu.Nakuba lungekho uphawu oluphelele, ukuguquguquka nokwenza ngokwezifiso ama-C-rings ngokuqinisekile kuwenza abe inketho ethakazelisayo nengase ibe usizo kwamanye amadivaysi ezokwelapha nawokuxilonga.Lolu wuphawu olulula uma kuqhathaniswa olulungele ingcindezi ephansi (<500 psi) kanye nezinhlelo zokusebenza zejubane eliphansi (<100 ft/min) lapho kudingeka khona ukungqubuzana okuphansi.Kulezi zindawo, ama-C-ring anganikeza isixazululo esingcono sokuvala kunezindandatho ze-elastomeric O-rings noma ezinye izinhlobo zezimpawu ezijwayelekile, ezinikeza abaklami ikhono lokwandisa impilo yesevisi nokunciphisa amazinga omsindo ngaphandle kokuguqulwa kwemishini ebizayo.
