Lub nplhaib O-ring yog ib hom kev foob uas siv los tiv thaiv cov kua los yog roj hauv ntau yam kev siv, xws li cov kav dej, li qub, twj tso kua mis, lub tog raj kheej, thiab lwm yam.
O-ring yog ib lub nplhaib zoo li cov roj hmab los yog lwm yam khoom siv elastomeric uas haum rau hauv qhov zawj ntawm qhov chaw sib txuas thiab tsim ib lub foob kaw ntom nti thaum compressed. O-ring kuj tuaj yeem ua lub cushion, spacer, lossis vibration dampener.
Lub O-ring ua haujlwm los ntawm kev tsim ib qho kev thaiv ntawm ob lossis ntau qhov chaw uas muaj kev sib cuag nrog ib leeg. Thaum cov npoo raug nias ua ke, O-ring deforms thiab ua rau qhov sib txawv ntawm lawv, tsim kom muaj lub foob uas thaiv cov dej los yog roj. Lub foob yog tswj hwm los ntawm lub zog elastic ntawm O-ring, uas sim rov qab mus rau nws qhov qub.
Kev ua tau zoo ntawm lub foob yog nyob ntawm ntau yam, xws li cov khoom siv, qhov loj me, cov duab, thiab qhov nyuaj ntawm O-ring, qhov qauv tsim, qhov siab thiab kub ntawm cov kua lossis roj, thiab kev sib raug zoo ntawm O-ring nrog. cov kua los yog roj.
O-ring tuaj yeem ua los ntawm ntau yam ntaub ntawv, xws li nitrile, silicone, viton, EPDM, neoprene, thiab lwm yam. Txhua yam khoom muaj nws cov khoom thiab qhov zoo, nyob ntawm qhov kub, siab, thiab tshuaj tiv thaiv uas koj xav tau rau koj daim ntawv thov.
Piv txwv li, nitrile yog ib yam khoom siv thiab kev lag luam uas muaj kev tiv thaiv zoo rau cov roj, dej, thiab kev puas tsuaj, tab sis nws tsis haum rau qhov kub thiab txias los yog ozone raug. Silicone yog cov khoom siv tau yooj yim thiab muag muag uas tuaj yeem tiv taus qhov kub thiab txias, tab sis nws tsis zoo rau cov roj thiab puas. Viton yog cov khoom zoo tshaj plaws uas muaj kev tiv thaiv zoo rau qhov kub thiab txias, tshuaj lom neeg, thiab ozone, tab sis nws kim dua thiab nyuaj rau kev sib raug zoo dua li lwm cov ntaub ntawv.
Lub nplhaib O-ring kuj tuaj yeem muaj cov duab sib txawv thiab qhov ntau thiab tsawg, xws li puag ncig, square, quad, lossis x-ntiv nplhaib. Round O-rings yog qhov ntau tshaj plaws thiab ntau yam duab, raws li lawv tuaj yeem haum rau feem ntau cov qauv O-ring grooves.
Square O-rings muaj qhov chaw tiaj tus uas tuaj yeem muab ntau qhov chaw sib txuas thiab kev sib khi zoo dua li puag ncig O-rings, tab sis lawv xav tau qhov sib sib zog nqus. Quad O-rings muaj plaub lub lobes uas tuaj yeem txhim kho lub foob kev ruaj ntseg thiab txo kev sib txhuam, tab sis lawv nyuaj rau nruab thiab tshem tawm dua li puag ncig O-rings. X-rings muaj ob qhov chaw sib khi uas tuaj yeem muab kev sib khi zoo dua thiab qis qis dua li cov O-rings, tab sis lawv kim dua thiab xav tau qhov tshwj xeeb zawj.
