I-Spring Energzied Seals iwuphawu olusebenza kahle kakhulu olunesiphethu esikhethekile ngaphakathi kwe-PTFE emise okwe-U.
Amandla entwasahlobo afanelekile ahlanganiswe nomfutho we-fluid wesistimu icindezela kancane udebe oluvalayo (ubuso) bubheke ebusweni bensimbi ukuze kukhiqizwe uphawu oluhle kakhulu.Umthelela wokwenza kusebenze wentwasahlobo unqoba ukugqama okuncane kwendawo yokuhlangana kwensimbi kanye nokuguga kodebe oluvalayo, kuyilapho kugcinwa ukusebenza okufiswayo kokuvala.Ama-Spring Energzied Seals asebenza kakhulu ezinhlelweni eziningi ezahlukahlukene.Zisetshenziswa lapho ukumelana okuhle kwamakhemikhali emithonjeni yezindaba kudingekile noma lapho uphawu ludingeka ukuze lusebenze emazingeni okushisa aphezulu, nalapho kudingeka khona ukucindezela okuhle nokucindezela izakhiwo.
I-PTFE iwuphawu olukwazi ukumelana namakhemikhali kangcono kune-perfluoroelastomer, ukumelana nokushisa okuhle futhi ingasetshenziswa oketshezini lwamakhemikhali amaningi, izincibilikisi, uketshezi olunamanzi kanye namafutha okugcoba, anokuvuvukala okuncane kokusebenza kokuvala isikhathi eside.Ukusetshenziswa kwebanga lokushisa kungaba kusukela esiqandisini kuya ku-300 ℃, ingcindezi esuka ku-vacuum kuya ku-ultra-high pressure force 700kg ehamba ngesivinini efika ku-20m / s, kanti intwasahlobo ingasetshenziswa ekuphenduleni ukusetshenziswa okuhlukile kwemvelo, ukukhetha. yensimbi engagqwali, i-Elgiloy Hastelloy, ngakho-ke ingasetshenziswa ezikhathini ezihlukahlukene zoketshezi olushisa kakhulu lokushisa eliphezulu.
Ama-Spring Energzied Seals angenziwa ngokuya nge-AS568A standard O-ring groove (efana ne-radial shaft seal, piston seal, axial face seal, njll.), ithathele indawo ngokuphelele indandatho ye-O, ngoba ayikho inkinga yokunwetshwa, ngakho-ke ingagcina ukusebenza kahle kokuvala uphawu isikhathi eside.Isibonelo, imbangela evame kakhulu yokuvuza kwezimpawu ze-shaft mechanical ezisetshenziswa ezinkambisweni ze-petrochemical akuyona nje ukugqoka okungalingani kwamasongo e-sliding, kodwa futhi ukuwohloka nokulimala kwe-O-rings.
Ngaphezu kwezinhlelo ezibalulwe ngenhla zokuvala izinga lokushisa eliphezulu kanye nezindawo ezigqwalile, i-Spring Energzied Seals ifaneleka kakhulu ukuvala amasilinda womoya, esikhundleni sokuminyaniswa komumo we-U- noma u-V ukuze kuzuzwe ukusebenza kahle kokuvala nempilo yesevisi ngenxa yokungqubuzana kwayo okuphansi kwe-coefficient. udebe oluvalayo, ingcindezi yokuxhumana evalekayo ezinzile, ukumelana nengcindezi ephezulu, kanye nokubekezelela iphutha elikhulu le-radial run-out kanye nosayizi we-groove.
Umhlahlandlela wokufaka we-Spring Energzied Seals:
Ama-Spring Energzied Seals kufanele afakwe kuphela emiseleni evulekile.
Ukuze uthole ukulingana okugxile futhi okungenangcindezi, landela lezi zinyathelo ezingezansi.
1. Faka uphawu endaweni evulekile.
2. Faka ikepisi, ngaphandle kokuyiqinisa kuqala.
3. faka i-shaft.
4. Lungisa ikepisi emzimbeni.
Izicelo:
Ama-Spring Energzied Seals ama-seal akhethekile aklanyelwe ukugqwala kwezinga lokushisa eliphezulu, ukuthambisa okunzima kanye nezicelo zokungqubuzana okuphansi.Inhlanganisela yezinhlanganisela ezahlukene ze-PTFE, amapulasitiki wobunjiniyela bezinga eliphezulu neziphethu zensimbi ezikwazi ukumelana nokugqwala zifaneleka ngokuphelele ukuhlangabezana nezidingo ezikhulayo nezihlukahlukene zemboni, izicelo ezijwayelekile zimi kanje.
1. ama-axial seal okulayisha nokuthulula amalunga okujikeleza kwengalo.
2. Izigxivizo zamavalvu esifutho sikapende noma ezinye izinhlelo zikapende.
3. Izivalo zamaphampu evacuum.
4. Izivalo zeziphuzo, amanzi kanye nempahla yokugcwalisa ubhiya (isb. amavalvu okugcwalisa) kanye nemboni yokudla.
5. Izivalo zezimboni zezimoto nezasemoyeni, njengesiteringi sikagesi.
6. Izigxivizo zemishini yokwenza amamitha (ukungqubuzana okuphansi, impilo ende).
7. Izigxivizo zeminye imishini yenqubo noma imikhumbi yokucindezela.
Umgomo wokuvala:
Inhlanganisela ye-PTFE plate spring seal emise okuka-U (Spring Energzied Seals) ngokucindezela okufanelekile kwentwasahlobo kanye nokucindezela koketshezi lwesistimu, udebe oluvalayo luphume bese ucindezela ngobumnene indawo yensimbi evaliwe ukuze kwakheke umphumela wokuvala omuhle kakhulu.
