Na apo-oHoʻohana nui ʻia no ka hoʻopaʻa paʻa ʻana a me ka hoʻopaʻa ʻana i ka neʻe.Ke hoʻohana ʻia no ka sealing rotary motion, ua kaupalena ʻia i nā mea hoʻopaʻa haʻahaʻa rotary sealing haʻahaʻa.Hoʻokomo pinepine ʻia ka O-ring i loko o kahi ʻāwī me kahi ʻāpana ʻāpana ʻehā ma ka pōʻai o waho a i ʻole ka pōʻai i loko e pāʻani i kahi hana sila.Hoʻokani maikaʻi nā sila O-ring i ka sila a me ka haʻalulu i nā kaiapuni e like me ka pale ʻana i ka aila, ka waikawa a me ka alkali, abrasion, a me ka erosion kemika.
Nā hiʻohiʻona o-ring:Loaʻa i ka O-ring ka hana hoʻopaʻa sila maikaʻi a me ke ola hana lōʻihi.ʻO ke ola hana o ka sila hoʻoikaika ikaika he 5-10 mau manawa kiʻekiʻe ma mua o nā huahana sealing rubber maʻamau, a hiki i nā manawa he nui.Ma lalo o kekahi mau kūlana, hiki ke ola like me ka matrix sealing..He liʻiliʻi ke kūʻē o ka frictional o ka O-ring, a ua like ka dynamic friction a me static, ʻo ia ka 1/2-1/4 o ka friction o ka "0"-shaped apo apo, hiki ke hoʻopau i ke ʻano "kolo" o ka holo haʻahaʻa a me ka neʻe haʻahaʻa.ʻO ka O-ringi ka mea hiki ke hoʻopaʻa ʻia, a loaʻa iā ia kahi hana uku elastic ma hope o ke kau ʻana o ka ʻili o ka sila.Loaʻa i nā O-rings nā waiwai lubricating maikaʻi.Hiki ke hoʻohana ʻia e like me ke sila lubrication ʻole aila.He ʻano maʻalahi ka O-ring a maʻalahi ke hoʻokomo.O-ring kaomi hana: 0-300MPa;ka wikiwiki hana: ≤15m / s;mahana hana: -55-250 degere.ʻO ke apo e pili ana i ka medium: hydraulic oil, gas, wai, mud, crude oil, emulsion, water-glycol, acid.
Nā pōmaikaʻi o nā O-rings:Hoʻohālikelike ʻia me nā ʻano apo sealing ʻē aʻe, loaʻa nā O-rings i kēia mau mea maikaʻi: He kūpono no nā ʻano sealing like ʻole: static sealing, dynamic sealing, kūpono no nā ʻano mea like ʻole, ua hoʻohālikelike ʻia ka nui a me nā grooves. : ka neʻe ʻana, ka neʻe ʻana axial a i ʻole ka neʻe hui ʻana (e like me ka rotary reciprocating hui pū), kūpono no nā ʻano mea hoʻopaʻa hoʻopaʻa like ʻole: ʻaila, wai, kinoea, media kemika a i ʻole nā mea like ʻole i hui ʻia, ma ke koho ʻana i ka mea kūpono.
