PTFE kapena polima O-Rings ali ndi kukana kwambiri pafupifupi mankhwala onse kuphatikizapo zidulo, maziko, mafuta, nthunzi......
PTFE O-Rings Chiyambi
Kusasunthika kwa PTFE ku pafupifupi mpweya ndi madzi onse pakati pa -320 °F ndi +450 °F ndi chimodzi mwazinthu zachilendo kwambiri zikagwiritsidwa ntchito muzitsulo zosindikizira za O-Ring.Umphumphu wa PTFE udzanyozedwa pokhapokha akakumana ndi zitsulo zosungunuka zamchere ndi mankhwala ena opangidwa ndi halogenated.PTFE ndiye chinthu chomwe mungasankhire kuti muwonetsetse kuti chidindo cha O-Ring chili ndi sing'anga yosindikizidwa kapena kusindikiza pa kutentha kwakukulu.
Malangizo Opanga a PTFE O-Rings
Mchitidwe wokhazikika wa rabara O-Ring monga Per MIL-G-5514 nthawi zambiri umalimbikitsidwa pakayika makina ophatikizika pamagwiritsidwe amphamvu.TG O-Rings itha kugwiritsidwanso ntchito pazinthu zinazake.Popeza kusiyana kwakuthupi kwa PTFE ndi mankhwala a elastomeric ndikokwera kwambiri, njira zotsatirazi zopangira ndi kukhazikitsa zipereka zotsatira zabwino kwambiri zosindikizira malinga ndi magwiridwe antchito ndi moyo wosindikiza:
- Mosiyana ndi mphira O-Rings, PTFE O-Rings samakumana ndi kulephera kozungulira, chifukwa chake ndizotheka kuchepetsa m'lifupi mwa gland.
- PTFE O-Rings alibe conformity mphira O-Rings;chifukwa chake ndikofunikira kuchepetsa kufinya kwapang'onopang'ono kofanana ndi komwe kumapangidwira mphira kuti muchepetse kusonkhana.
Malangizo oyika polima O-Rings
Kuteteza PTFE O-Rings kuti asatengeke kapena kunyowa panthawi yoyika ndikofunikira.Gouging imatha kuchitika potambasula ma O-Rings pamapewa akuthwa kapena ulusi.Itha kupewedwa pokweza mphete kumadera akuthwa pogwiritsa ntchito zida kapena kupereka zopumira pamakona kapena ma radii.Kutambasula pang'ono, ngati kuli kotheka pansi pa 10%, kumalimbikitsidwa panthawi ya O-Ring.Kugwiritsa ntchito mafuta otentha kapena kusamba m'madzi kumathandizira kutambasula ngati pakufunika.Kusintha kwa mapangidwe kapena njira zapadera zitha kufunikira pakukula kopitilira 20%.
PTFE imakonda kukwawa ngati ma thermoplastics onse.Khalidweli liyenera kuthetsedwa kuti tipewe kutaya katundu wosindikiza.Ndizotheka kuwongolera mphamvu ya kuzizira kozizira posintha miyeso monga momwe tafotokozera m'matebulo.
PTFE O-Rings ikhoza kupangidwa kuchokera kuzinthu zosiyanasiyana monga PTFE yodzaza ndi graphite, bronze ndi galasi.Nthawi zambiri, zofunikira zimatha kukwaniritsidwa ndi PTFE yosadzazidwa.
Ubwino wa PTFE O-Rings
- O-Rings ndi imodzi mwamayankho abwino pamakina otsika kwambiri
- Kugwirizana kwachilengedwe kwa PTFE
- Kutentha kwakukulu kwapakati pa -320 °F ndi +500 °F
- Mitengo yofulumira komanso kutembenuka mwachangu
- Kusankha kwakukulu kwa O-Rings pakati pa 0.110 ″ ndi ~ 40 ″;saizi yapadera ikupezeka mukapempha
- Vacuutor to high-pressure, ikagwiritsidwa ntchito limodzi ndi mphete yoyenera yosungira
