O-RING - ʻO ka mea paʻa a pololei i nā ʻōnaehana hydraulic

I loko o ka ʻōnaehana hydraulic, aia kahi ʻāpana liʻiliʻi maʻamau e pāʻani i kahi kuleana nui, a ʻo ia ka O-ring.Ma ke ʻano he mea hoʻopaʻa paʻa a pololei hoʻi, he kuleana koʻikoʻi nā O-rings i ka hana o nā ʻōnaehana hydraulic.E hoʻolauna kēia ʻatikala i ke ʻano, ka hana a me ka hoʻohana ʻana o O-ring i ka ʻōnaehana hydraulic.

ʻO ka hoʻolālā a me nā mea o ke apo ʻO ka O-ring he sila me ka annular cross-section, i hana ʻia me nā mea plastic e like me ka rubber a i ʻole polyurethane.ʻO ke ʻano o kona ʻāpana ʻāpana he "O", no laila ua kapa ʻia ʻo ia ʻo O-ring.Hoʻokaʻawale ʻia ke ʻano o ka O-ring i ʻekolu mau ʻāpana: ke anawaena o loko, ke anawaena o waho a me ka mānoanoa.ʻO ke anawaena o loko a me ke anawaena o waho e hoʻoholo i ke kūlana hoʻonohonoho a me ka laulā o ka O-ring, aʻo ka mānoanoa e hoʻoholo i ka hopena sealing o ka O-ring.

ʻO ka hana o ka O-ring ʻO ka hana nui o ka O-ring ka hāʻawiʻana i kahi sila, kahi e pale ai i ka leakage o ka wai a me ke kinoea i loko o ka pūnaewele hydraulic.Ma muli o nā waiwai elastic o ka lāʻau a me nā mea ʻē aʻe, hiki i ka O-ring ke hoʻopili pono i ka ʻili o ke kūlana sealing e pale ai i ka leakage o ka wai a i ʻole ke komo ʻana o ka media.I ka manawa like, loaʻa i ka O-ring nā hiʻohiʻona o ka pale ʻana i ka lole, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka ʻaila a me ka pale ʻana i ka corrosion, i hiki ai iā ia ke mālama i ka hana sila maikaʻi ma lalo o nā kūlana hana paʻakikī.

Hoʻohana nui ʻia nā O-rings O-rings i nā ʻōnaehana hydraulic, e like me nā cylinders hydraulic, nā puka wai, nā mea pneumatic, nā ʻōnaehana brake automotive, a me nā mea ʻē aʻe. ka hana kūpono o nā ʻōnaehana hydraulic.ʻO nā noi no nā O-rings me nā mīkini ʻenehana, aerospace, moana a me nā kaʻa.

ʻOiai he mea liʻiliʻi paha ka O-ring i kahi ʻōnaehana hydraulic, ʻaʻole hiki ke nānā ʻia kona koʻikoʻi.Ma keʻano he mea hoʻopili paʻa a pololei, hiki i ka O-ring ke hōʻoia i ka hana maʻamau o ka'ōnaehana hydraulic a pale i ka leakage o ka wai a me ke kinoea.No laila, i ka hoʻolālā ʻana a me ka hoʻohana ʻana i ka ʻōnaehana hydraulic, pono mākou e noʻonoʻo pono i ke koho ʻana o nā mea waiwai, hoʻokomo a hoʻohana ʻana i ka O-ring e hōʻoia i ka hilinaʻi a me ka palekana o ka ʻōnaehana.

ʻO nā O-rings kahi mea hoʻopaʻa maʻamau i hoʻohana nui ʻia i nā ʻano ʻano like ʻole, ʻoi loa i ka ʻenekinia mechanical a me ka hoʻokele wai.Loaʻa iā ia kona inoa ma muli o kona ʻano cross-sectional e like me ka huapalapala "O".Hana ʻia nā O-rings i nā mea maʻalahi e like me ka rubber, silicone, polyurethane, a me nā mea ʻē aʻe.

Eia kekahi mau hiʻohiʻona nui o nā O-rings:

ʻO ka hana hoʻopaʻa sila maikaʻi loa: Hiki i nā O-rings ke hāʻawi i ka hopena sealing maikaʻi loa no ka mea hiki i ka elasticity o ka mea ke hana i kahi sila paʻa i nā ʻāpana pili.ʻO kēia hiʻohiʻona e hana maikaʻi loa i nā O-rings i ka pale ʻana i ka leakage o nā wai a me nā kinoea.

Hiki ke hoʻololi ikaika: Hiki ke hoʻohanaʻia nā O-rings i ka hoʻohuiʻana i nā'āpana o nāʻano nui a me nāʻano likeʻole, e like me ka poepoe, square, oval, a me nā mea'ē aʻe.

ʻO nā hiʻohiʻona pale wela kiʻekiʻe a haʻahaʻa paha: Hiki i nā apo-O ke hana ma lalo o nā ʻano wela like ʻole, me ka wela kiʻekiʻe a me nā kaiapuni haʻahaʻa haʻahaʻa.Hiki iā ia ke mālama i kona elasticity a me ka hoʻopaʻa ʻana i nā waiwai no ka manawa lōʻihi ma lalo o nā kūlana wela.

ʻO ka pale ʻana i ka corrosion ikaika: Hoʻohana pinepine ʻia nā O-rings i ka ʻoihana kemika a me nā mea hoʻokele wai no ka mea kūʻē lākou i nā mea kemika like ʻole, me nā waikawa, alkalis, solvents, etc.

Kākoʻo kila kila: ʻO kekahi mau o-rings he kākoʻo kākoʻo o ke kila kila a i ʻole nā ​​mea metala ʻē aʻe no ka ikaika hou a me ka lōʻihi.Hoʻohana maʻamau kēia hoʻolālā i nā noi kiʻekiʻe a me nā noi wela.

Maʻalahi e hoʻouka a hoʻololi: Ma muli o kona maʻalahi a me ka compressibility, hiki ke hoʻokomo ʻia nā O-rings ma ka hoʻopili ʻana i nā ʻāpana me ka maʻalahi.He mea maʻalahi hoʻi e wehe a hoʻokomo i kahi O-ring hou ma kahi hoʻokahi ke koi ʻia ke pani.

ʻO nā mea āpau, ʻo nā O-rings kahi mea hoʻopaʻa koʻikoʻi i hoʻohana ʻia i nā ʻano noi.Hāʻawi lākou i ka hana sealing hilinaʻi, hiki ke hoʻololi i ka ikaika, a loaʻa nā mea maikaʻi o ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa corrosion.Ke kūʻai a hoʻohana i nā O-rings, pono e koho i ka mea kūpono a me ka nui e like me nā pono kikoʻī e hōʻoia i kāna hana maikaʻi loa.
