AboutPTFE o-mheteuye chitubu-chakaremerwa PTFE nhoroondo sezvinotevera:
Mumashandisirwo ane simba anoda kuiswa chisimbiso pane yakaderera kusvika pakati pekumhanya uye kumanikidza, mainjiniya ekugadzira anotsiva kusaita zvakanaka elastomeric.O-mheteine chitubu-yakatakura PTFE "C-ring" zvisimbiso.
Kana maO-rings nedzimwe nzira dzechinyakare dzekuisa chisimbiso dzisingashande, mainjiniya ekuongorora uye ekuendesa zvinodhaka ari kutora nzira itsva, inodhura yekusimudzira kushanda kwezvigadzirwa zvavo zvemidziyo iripo: PTFE “C-Ring” spring seals.
C-zvisimbiso zvakatanga kugadzirwa kuti zvigadzirise zviridzwa zvichishandisa piston inodzokerana pa 5 tsoka paminiti ichishanda mubhavhu remvura rinenge 100 ° F.Mamiriro ekushanda ari munyoro, asi ane kushivirira kukuru.Iyo yekutanga dhizaini yaida elastomeric o-ring yekusimbisa piston, asi o-ring yaisakwanisa kuchengetedza chisimbiso chechigarire, zvichiita kuti mudziyo uderedze.
Mushure mekunge prototype yavakwa, mainjiniya akatanga kutsvaga dzimwe nzira.U-mhete kana yakajairwa miromo zvisimbiso, inowanzoshandiswa mumapistoni, haina kukodzera nekuda kwekushivirira kukuru kweradial.Izvo hazvigoneke zvakare kudziisa pane yakazara-stage recesses.Kuiswa kunoda kutambanudza zvakanyanya, izvo zvinotungamirira ku deformation uye kukundikana kusati kwasvika kwechisimbiso.
Muna 2006, NINGBO BODI SEALS .,LTD yakauya nechisarudzo chekuedza: chitubu che canted helical chakaputirwa muPTFE C-ring.Kudhinda kunoshanda sezvaitarisirwa.Kubatanidza iyo yakaderera friction properties yePTFE ine streamlined boot geometry, "C-Rings" inopa yakavimbika, chisimbiso chechigarire uye yakapfava uye yakanyarara kupfuura O-Rings.Mukuwedzera, C-zvindori zvakakodzera kune yakazara-nhanho o-mhete, iyo isingawanzo kurudzirwa kune inelastic zvinhu.Saka, iyo C-ring inogona kuiswa pasina kushandura yekutanga dhizaini dhizaini kana kushandisa chero yakakosha maturusi.
Chekutanga C-chisimbiso chaive nemakore maviri.Kushandiswa kweC-rings kunonatsiridza mashandiro echigadzirwa uye kunowedzera hupenyu hwemidziyo nekudzikisa nguva yekudzikira uye mari yekugadzirisa.
Midziyo yekufungidzira yekurapa, mapombi einsulin, mafevha, uye michina yekuendesa zvinodhaka kazhinji inoshandisa O-mhete kuvhara nzvimbo pfupi dzeaxial.Asi kana yakanyanyisa radial deflection hunyanzvi hunodiwa, O-mhete haigone kutsiva izvi, kazhinji zvichikonzera kupfeka, deformation yekusingaperi, uye kuvuza.Pasinei nekukanganisa uku, mainjiniya anoenderera mberi nekushandisa o-mhete nekuti mamwe magadziriso (eg U-mikombe, zvisimbiso zvemiromo) haagone kusangana neradial deflection zvinodiwa uye kazhinji zvinoda nzvimbo yakawanda yeaxial kupfuura o-mhete.
Iyo C-ring yakasiyana pakuti inogona kupinda munzvimbo diki yeaxial inowanzopihwa yeO-ring, nepo zvisimbiso zvakajairika hazvigone.Mukuwedzera, C-mhete inogona kunyatsogadziriswa kuti ienderane nezvinodiwa zvekushandisa.Inogona kugadzirwa ne-ultra-tete uye inochinjika lip ye cryogenic application kana gobvu muromo kune ane simba maapplication uko chisimbiso chinoda kuwedzera kupfeka kuramba.
Nekuti C-mhete inobvumira zvese kutenderera uye kudzoreredza kufamba, iwo mhinduro inochinja-chinja yezvakasiyana zvigadzirwa zvinoda yakaderera kusvika yepakati kumhanya chisimbiso, zvinosanganisira marobhoti ekurapa, inotakurika michina yekurapa, uye probe/tubing zvinongedzo.C-mhete inobvumira kushivirira kwakakura kwakakura-kupfuura kashanu kupfuura zvisimbiso zvakajairwa zvechikamu chimwe chete.Rudzi rwekushivirira runobva pane ambient pressure, rudzi rwepakati uye nepamusoro pemamiriro ekurapa.C-mhete inoshandawo zvakanaka mune static application apo zvikamu zvinoda kuchengetedzwa kubva kune zvakatipoteredza zvinosvibisa.
Nekubvisa zvinhu zvePTFE kubva kune yekutanga C-ring boot dhizaini, mainjiniya akakwanisa kuwedzera kusimba kwayo uye kuchinjika.Nekuda kweizvozvo, C-mhete dzakaratidza kuve dzakatambanudzwa uye dzinochinjika kupfuura zvaitarisirwa pakutanga, zvichiita kuti dzive dzakakodzera kune dzisiri-denderedzwa application.C-mhete dzakashandiswa mumapombi ekutumira zvinodhaka ane oval pistons.Nekuti chisimbiso muromo unogona kugadzirwa kubva kumhandara PTFE kana kuzadzwa PTFE, iyo C-ring chisimbiso chinoshandiswa zvakasiyana-siyana chinoenderana nesimbi uye mapurasitiki.
C-mhete, yakatanga kugadzirirwa kushandiswa nemvura-based diagnostic tools, inosanganisira PTFE-jacketed helical springs.Asi C-mhete inogonawo kugadzirwa uchishandisa helical band zvitubu se activators.Nekutsiva canted helical zvitubu nezvitubu zvehelical band, C-mhete inogona kupa yakanyanya kuvharika yekubatanidza kumanikidza, yakanakira cryogenic kana static application.
Bal Seal Engineering inodana C-ring yayo "chisimbiso chakakwana chenyika isina kukwana" nekuda kwekugona kwayo kupa hupenyu hwesevhisi hwakawedzerwa munzvimbo dzine mapundu, kupera kwepamusoro uye humwe hunhu hwekugadzira hunosiyana zvakanyanya.Kunyange zvazvo pasina chisimbiso chakakwana, kushandiswa kwakasiyana-siyana uye kugadzirisa kweC-rings zvechokwadi kunoita kuti ive inonakidza uye inogona kubatsira sarudzo mune mamwe mishonga yezvokurapa uye yekuongorora.Ichi chisimbiso chisina kuremerwa chakanakira kudzvinyirira kwakaderera (<500 psi) uye yakaderera kumhanya (<100 ft/min) maapplication uko kuderera kunodiwa.Kune idzi nharaunda, C-mhete inogona kupa mhinduro iri nani yekuisa chisimbiso pane elastomeric O-mhete kana mamwe marudzi akajairwa chisimbiso, ichipa vagadziri kugona kwekuwedzera hupenyu hwebasa uye kuderedza ruzha pasina kudhura gadziriso yemidziyo.
