O-mphete angagwiritsidwe ntchito m'njira zosiyanasiyana chifukwa amapangidwa kuchokera ku zipangizo zosiyanasiyana.O-mphete nthawi zambiri amapangidwa ndi mphira, kapena makamaka polima / elastomer.Ma polima awa nthawi zambiri amachiritsidwa ndi vulcanization, zomwe zimapangitsa kuti pakhale zida zolimba, zolimba komanso zotanuka kwambiri.
P-mphete ndizomwe zimapangidwira makina osindikizira chifukwa cha mtengo wake wotsika, kuphweka kwa kupanga, ntchito yodalirika, ndi zofunikira zosavuta kuziyika.O-mphete amakumana ndi zovuta za makumi a megapascals (kilo-mapaundi).Ma O-ringing angagwiritsidwe ntchito pamayendedwe osasunthika komanso m'machitidwe osunthika pomwe pali kusuntha kwakanthawi pakati pa zigawo, monga ma shaft a mapampu ozungulira ndi ma pistoni a silinda ya hydraulic.
O-ring ndi yoyenera kuyika pazida zosiyanasiyana zamakina, pansi pa kutentha komwe kwatchulidwa, kupanikizika, ndi zofalitsa zosiyanasiyana zamadzimadzi ndi mpweya, zimatha kugwira ntchito yosindikiza mu static kapena kusuntha.Mitundu yosiyanasiyana ya zisindikizo imagwiritsidwa ntchito kwambiri pazida zamakina, zombo, magalimoto, zida zakuthambo, makina opangira zitsulo, makina opangira mankhwala, makina omanga, makina omanga, makina opangira migodi, makina amafuta, makina apulasitiki, makina aulimi, ndi zida zosiyanasiyana ndi mita.chinthu.O-mphete amagwiritsidwa ntchito makamaka kusindikiza static ndi kubwereza kusindikiza.Akagwiritsidwa ntchito posindikiza zosindikizira, amangokhala ndi zosindikizira zotsika kwambiri.Mphete ya O nthawi zambiri imayikidwa poyambira ndi gawo lopingasa la makona atatu pabwalo lakunja kapena lamkati kuti ligwire ntchito yosindikiza.Ma O-rings amagwirabe ntchito yabwino kusindikiza ndi kuyamwa modzidzimutsa m'malo monga kukana mafuta, kukana kwa asidi ndi alkali, kugaya, ndi kukokoloka kwa mankhwala.Chifukwa chake, mphete za O ndizomwe zimagwiritsidwa ntchito kwambiri pamakina a hydraulic ndi pneumatic transmission.
FKM ndi NBR elastomers amasankhidwa ndi Makasitomala ambiri ku Xingtai xinchi.Kuphatikiza apo, kutentha kwapakati pakati pa -15 ° C ndi 110 ° C kumathandizidwa ndi mankhwala onsewa, zomwe zimapangitsa kuti zinthuzo zikhale zabwino kwambiri pakugwiritsa ntchito mafakitale.Kwenikweni, Zida zonsezi ndizoyenera kugwiritsidwa ntchito pa -30 mpaka 125 ° C.FKM ili ndi mwayi pamatenthedwe otsika komanso kutentha kwambiri.FKM rabara ndi yofewa komanso yotanuka.Koma mtengo wa FKM elastomer wakwera kuyambira Ogasiti chaka chino, mtengo wake ndiwokwera kuposa kale.NBR ili ndi mwayi pang'ono poyerekeza kupirira kwakanthawi kochepa.NBR yokhala ndi zotsutsana zenizeni ndi ma acid, alkali wosungunuka, madzimadzi amadzimadzi, madzi, madzi a ethylene glycol ndi mowa.FKM ili ndi kukana kwapadera kwa nthunzi, ozoni, kupsinjika kwa seti, kukana kwamitundu yotakata, ma hydrocarbon onunkhira, ma hydrocarboni a chlorinated, madzi osayatsa a hydraulic fluid, ukalamba, ma acid amphamvu, ma brake fluid, acetone, halogenated hydrocarbons, vacuum ndi ma acid ambiri.
