saizi dzakasiyana rabha hnbr epdm nbr 70 yekuisa chisimbiso oring o-ring o-ring
O-mhete dzinoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nekuda kwekugona kwavo kugadzira chisimbiso pakati penzvimbo mbiri.Sarudzo yeO-ring material inoenderana nemashandisirwo uye nharaunda yaichashandiswa mairi. Hezvino zvimwe zvinowanzo shandiswa paO-rings:
Nitrile (NBR): Ichi chinhu chakakurumbira cheO-rings nekuda kwekugona kwayo kupikisa mafuta, mafuta, uye mvura.Inogona kumira tembiricha inosvika 100°C.
Viton (FKM): Viton is fluorocarbon elastomer ine yakanakisa makemikari kuramba, kunyanya kune yakanyanya tembiricha uye makemikari ane hutsinye.Inogona kumira kutonhora kusvika ku200 ° C.
Silicone (VMQ): Silicone O-mhete dzinozivikanwa nekuchinjika kwadzo uye kuramba kune tembiricha yakanyanyisa, yakakwira uye yakaderera.Dzinokwanisa kutsungirira tembiricha kubva -60°C kusvika 200°C.
EPDM irabha rekugadzira iro rinopikisa zvakanyanya mamiriro ekunze, ozone, uye UV mwaranzi.Inonyanya kushandiswa mumashandisirwo ekunze uye inogona kumira kutonhora kusvika ku150 ° C.
Neoprene: Neoprene O-mhete dzinozivikanwa nekuramba kwavo kwakanaka kumafuta, mamiriro ekunze, uye ozone.Dzinogona kutsungirira tembiricha inosvika 100°C.
