ubukhulu obahlukeneyo irabha hnbr epdm nbr 70 yokutywina itywina oring o-ring o-ring
Amakhonkco e-O asetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yokukwazi kwabo ukudala itywina phakathi kweendawo ezimbini.Ukukhethwa kwezinto ze-O-ring kuxhomekeke kwisicelo kunye nendawo eya kusetyenziswa kuyo. Nazi ezinye izinto eziqhelekileyo ezisetyenziselwa i-O-rings:
I-Nitrile (NBR): Le yimathiriyeli eyaziwayo ye-O-rings ngenxa yokuxhathisa kwayo kakuhle kwi-oyile, amafutha kunye namanzi.Iyakwazi ukumelana namaqondo obushushu ukuya kutsho kwi-100°C.
I-Viton (FKM): I-Viton yi-elastomer ye-fluorocarbon enokumelana nekhemikhali egqwesileyo, ngakumbi kumaqondo obushushu aphezulu kunye neekhemikhali ezinzima.Iyakwazi ukumelana namaqondo obushushu ukuya kuma 200°C.
I-Silicone (VMQ): I-Silicone O-rings iyaziwa ngokuguquguquka okugqwesileyo kunye nokuchasana namaqondo okushisa aphezulu, aphezulu naphantsi.Ziyakwazi ukumelana namaqondo obushushu ukusuka ku -60°C ukuya kuma-200°C.
I-EPDM yirabha yokwenziwa ekwazi ukumelana nemozulu, i-ozone, kunye nemitha ye-UV.Iqhele ukusetyenziswa kwizicelo zangaphandle kwaye inokumelana namaqondo obushushu ukuya kutsho kwi-150°C.
I-Neoprene: I-Neoprene O-izangqa ziyaziwa ngokuxhathisa kwazo kakuhle ioli, imozulu kunye ne-ozone.Ziyakwazi ukumelana namaqondo obushushu ukuya kutsho kwi-100°C.
