Kugwiritsa ntchito mphete ya PTFE

Spiral shaft imasindikiza ndi chimodzi kapena zingapoPTFE mpheteAmapangidwa kuti athe kupirira mikhalidwe yosinthika, kutentha kwambiri, zolemera kwambiri komanso kuthamanga kowuma komwe zisindikizo zodziwika bwino za shaft zopangidwa ndi elastomeric kukonza milomo sizingathe kupirira.Gawo lalikulu la zosakaniza za PTFE zimavomerezedwa ndi FDA.

Mfundo zofunika kwambiri pazisindikizo za PTFE zikuphatikiza:

• High concoction kukana
• Kupirira kuthamanga mpaka 30 m/s (5 900 ft/mphindi)
• Kutentha kwakukulu kogwira ntchito, -70 mpaka +250 °C (-95 mpaka +480 °F)
• Kupirira zolemera mpaka 3,5 Mpa (500 psi)
• Kupirira youma kuthamanga

Maupangiri okhazikitsa mphete ya PTFE

Kuteteza PTFE O-Rings kuti zisakulidwe kapena kung'ambika mkati mwa kukhazikitsidwa ndikofunikira.Gouging imatha kuchitika ndikukulitsa ma O-Rings pamapewa akuthwa kapena zingwe.Itha kupeŵedwa pogwiritsa ntchito kuyika mphete pazida zakuthwa zakuthwa kapena kupereka zopumira pamakona kapena ma radii.Kutalikirako pang'ono, ngati kuli kotheka pansi pa 10%, kumaperekedwa pakati pa kukhazikitsidwa kwa O-Ring.Kugwiritsa ntchito mafuta otentha kapena shawa lamadzi kumalimbikitsa kutambasula kowoneka bwino ngati kuli kofunikira.Kuwonetsa kusintha kapena machitidwe odabwitsa angafunike pamikhalidwe yotambasula yopitilira 20%.

PTFE O-Rings ikhoza kupangidwa kuchokera ku zosakaniza zosiyanasiyana, mwachitsanzo, PTFE yodzaza ndi graphite, bronze ndi galasi.Nthawi zambiri, zofunikira zimatha kukwaniritsidwa ndi PTFE yosadzazidwa.

Ntchito Zochepa za mphete ya PTFE

Mphete ya PTFE yolimba kwambiri ndiyoyenera kugwiritsa ntchito ma static, otsika kwambiri.Amawonetsa mawonekedwe osinthika kwambiri a concoction chifukwa amapangidwa ndi zida zogona.Resilience pazigawo za zida zokwerera sayenera kuloleza mng'oma waukulu mukamagwiritsa ntchito O-Rings kusindikiza.Zida za PTFE zosadzazidwa sizingagwire ntchito mozizira, zomwe zimapangitsa kuti athamangitsidwe m'mabowo akamayambitsidwa popanda mphete zotsika.Ma O-Rings onse ndiabwino ndi mphete zake zosunga zobwezeretsera kuti apereke kukonza kokhazikika pamapulogalamu olemera kwambiri.Ulamuliro wa O-Rings umakulitsidwadi chifukwa mphamvu za mphete za Back-up zili m'chigawo cha kuthamangitsidwa.

Ubwino wogwiritsa ntchito mphete ya PTFE

Zomwe zikutsatiridwa ndi zowonjezera za PTFE Ring:

• O-Rings ndi amodzi mwamayankho abwino pamapangidwe ocheperako
• Kufanana kwakukulu kwapawiri kwa PTFE
• Kutentha kwakukulu kwapakati pa -320 °F ndi +500 °F
• Kuwunika mwachangu ndikuyambitsa pivot
• Kutsimikiza kwakukulu kwa O-Rings kwinakwake mozungulira 0.110" ndi ~ 40";kuyerekezera kodabwitsa kumafikiridwa popemphedwa
• Vacuum yolemera kwambiri, ikagwiritsidwa ntchito ngati gawo lolumikizana ndi mphete yoyenera yosunthira pansi

Mitundu iyi ya mphete ya PTFE imawunikira mzere wam'mbali kulimbikitsa madzi kuwayendetsa motsutsana ndi zigawo za zida zokwerera zokhazikika komanso zingapo za zinthu.
