I-PTFE O-Rings,O-Rings Ufakelo kunye noSetyenziso

I-PTFE okanye ii-O-Rings zepolymer zinokuchasana okugqwesileyo phantse kuzo zonke iikhemikhali ezibandakanya iiasidi, iziseko, ioyile, umphunga……

PTFE O-Rings Intshayelelo

Ukungagungqi kwe-PTFE kuzo zonke iigesi kunye nolwelo phakathi kwe -320 °F kunye +450 °F yenye yeempawu zayo ezingaqhelekanga xa isetyenziswa kwiinkqubo zokutywinwa kwe-O-Ring.Ingqibelelo ye-PTFE iya kuthotywa kuphela xa idibana neentsimbi ezinyibilikisiweyo zealkaline kunye nezinye iikhompawundi ezine-halogenated.I-PTFE yimathiriyeli yokuzikhethela ukuqinisekisa ukuhambelana kwe-O-Ring seal kunye ne-medium etywiniweyo okanye ukutywinwa kuluhlu olubanzi lobushushu.

Iingcebiso zoYilo lwe-PTFE O-Rings

Ukuziqhelanisa okusemgangathweni kwerabha ye-O-Ring efana ne-Per MIL-G-5514 ngokuqhelekileyo kuyacetyiswa kwimeko yofakelo lohlobo olucinezelayo kusetyenziso oluguquguqukayo.I-TG O-Rings ingasetyenziselwa usetyenziso oluthile.Kuba umahluko ngokwasemzimbeni we-PTFE kunye neekhompawundi ze-elastomeric ziphezulu kakhulu, olu yilo lulandelayo kunye neendlela zofakelo ziya kuzisa ezona ziphumo zibalaseleyo zokutywina ngokwemigaqo yokusebenza kunye nobomi botywino:

• Ngokungafaniyo ne-Rubber O-Rings, i-PTFE O-Rings ayifumani ukungaphumeleli kwe-spiral, kungoko kunokwenzeka ukunciphisa ububanzi bedlala.
• I-PTFE O-Rings ayinayo ukuhambelana kweerubha ze-O-Rings;ngoko ke kuyimfuneko ukunciphisa ukucudiswa kwecandelo elinqamlezileyo elihambelana nelo elichazwe kwirabha ukuze kube lula ukudibanisa.

Iingcebiso zoFakelo lwe-polymer O-Rings

Ukukhusela i-PTFE O-Rings ekufumaneni i-nicked okanye i-gouged ngexesha lofakelo kubalulekile.I-Gouging ingenzeka ngelixa usolula i-O-Rings phezu kwamagxa abukhali okanye imicu.Inokuphetshwa ngokulayisha amakhonkco kwiindawo ezibukhali ngokusebenzisa izixhobo okanye ukubonelela ngekhefu lekona okanye i-radii.Ukwelula okuphakathi, ukuba kunokwenzeka ngaphantsi kwe-10%, kucetyiswa ngexesha lokufakwa kwe-O-Ring.Ukusetyenziswa kweoyile eshushu okanye ibhafu yamanzi kunceda ukolula ngakumbi njengoko kufuneka.Utshintsho loyilo okanye iinkqubo ezizodwa zingafuneka kwiimeko zokolula ngaphezulu kwe-20%.

I-PTFE ithanda ukurhubuluza njengazo zonke ii-thermoplastics.Olu phawu kufuneka lujongwe ukuze kuthintelwe ukulahleka komthwalo wokutywina.Kunokwenzeka ukuhlaziya impembelelo yokuhamba okubandayo ngokuguqula imilinganiselo njengoko kunconywa kwiitafile.

I-PTFE O-Rings inokwenziwa ukusuka kwiintlobo ngeentlobo zeekhompawundi ezifana ne-graphite ezaliswe yi-PTFE, ubhedu kunye neglasi.Kwiimeko ezininzi, iimfuno zinokufezekiswa nge-PTFE engazaliswanga.

Izinto ezilungileyo ze-PTFE O-Rings

• I-O-Rings yenye yezisombululo ezifanelekileyo kwiinkqubo zoxinzelelo oluphantsi
• Ukuhambelana kwemichiza jikelele ye-PTFE
• Uluhlu olubanzi lobushushu obuphakathi kwe -320 °F kunye +500 °F
• Amaxabiso akhawulezayo kunye nokujika ngokukhawuleza
• Ukukhetha ubukhulu obubanzi be-O-Rings phakathi kwe-0.110" kunye ne-~40";ubungakanani obukhethekileyo buyafumaneka xa uceliwe
• Vacuum ukuya kuxinzelelo oluphezulu, xa isetyenziswe ngokudibeneyo neringi yogcino olufanelekileyo
