He aha ka O-Ring

Hiki ke hoʻohana ʻia nā O-rings i nā ʻano hana like ʻole no ka mea ua hana ʻia mai nā ʻano mea like ʻole.Hana ʻia nā apo-O i ka lāʻau, a i ʻole he polymer/elastomer.Hoʻomaʻa pinepine ʻia kēia mau polymers e ka vulcanization, e loaʻa ana i nā mea paʻa ikaika, lōʻihi a ʻoi aku ka elastic.

ʻO nā P-rings ka hoʻolālā mechanical maʻamau no nā sila ma muli o ko lākou kumukūʻai haʻahaʻa, ka maʻalahi o ka hana, ka hana hilinaʻi, a me nā koi hoʻonohonoho maʻalahi.Hoʻopili ʻia nā apo-O i nā ʻumi o nā megapascals (kilo-paona).Hiki ke hoʻohana ʻia nā O-rings i nā noi static a me nā noi ikaika kahi e neʻe ai ka neʻe ʻana ma waena o nā ʻāpana, e like me nā shafts o nā paila rotary a me nā pistons o nā cylinders hydraulic.

He kūpono ka O-ring no ka hoʻokomo ʻia ʻana ma luna o nā mea hana mīkini like ʻole, ma lalo o ka mahana i ʻōlelo ʻia, kaomi, a me nā ʻano wai like ʻole a me nā media kinoea, hiki iā ia ke pāʻani i kahi hana hoʻopaʻa i ke kūlana static a neʻe paha.Hoʻohana nui ʻia nā ʻano sila i nā mea mīkini, nā moku, nā kaʻa, nā lako aerospace, nā mīkini metallurgical, nā mīkini kemika, nā mīkini hana, nā mīkini hana, nā mīkini mining, nā mīkini ʻaila, nā mīkini plastik, nā mīkini mahiʻai, a me nā mea hana like ʻole a me nā mika.ʻeleʻele.Hoʻohana nui ʻia nā O-rings no ka hoʻopaʻa static a me ka hoʻopaʻa ʻana.Ke hoʻohana ʻia no nā hōʻailona hoʻoneʻe rotary, ua kaupalena ʻia i nā sila rotary haʻahaʻa.Hoʻokomo pinepine ʻia ka O-ring i loko o ke awāwa me kahi ʻāpana ʻāpana ʻehā ma ka pōʻai waho a i loko paha e pāʻani ai i kahi hana sila.He kuleana maikaʻi nā O- apo i ka sila a me ka haʻalulu ʻana i nā kaiapuni e like me ke kūpaʻa ʻaila, ka ʻakika a me ke kūpaʻa alkali, ka wili ʻana, a me ka hoʻoneʻe kemika.No laila, ʻo nā O-rings ka mea i hoʻohana nui ʻia i nā ʻōnaehana hydraulic a me ka pneumatic transmission.

E koho ʻia ʻo FKM a me NBR elastomers e ka hapa nui o nā mea kūʻai aku ma Xingtai xinchi.Hoʻohui ʻia, hoʻohana ʻia nā noi wela haʻahaʻa ma waena o -15°C a me 110°C e nā pūhui ʻelua, e hana ana i kēlā me kēia mea i koho maikaʻi loa no ka hoʻohana ʻana i ka ʻoihana.ʻOiaʻiʻo, kūpono nā mea ʻelua no ka hoʻohana ʻana ma ka pae -30 a 125 ° C.Loaʻa i ka FKM ka pōmaikaʻi i nā haʻahaʻa haʻahaʻa a me nā mahana kiʻekiʻe.ʻOi aku ka palupalu a me ka elastic FKM rubber.Akā ke piʻi nei ke kumukūʻai o FKM elastomer mai ʻAukake o kēia makahiki, ʻoi aku ka kiʻekiʻe o ke kumukūʻai ma mua.Loaʻa ka maikaʻi iki o ka NBR i ka hoʻohālikelike ʻana i ke kūpaʻa pōkole.Loaʻa i ka NBR nā kūʻē kūʻokoʻa i nā ʻakika, nā alkalies i hoʻoheheʻe ʻia, nā wai hydraulic, ka wai, nā wai ethylene glycol a me nā waiʻona.Loaʻa i ka FKM ke kū'ē kū'ē i ka mahu, ka ozone, ka hoʻoemi ʻana, ke kūpaʻa kemika ākea, ka hydrocarbons aromatic, ka wai hydraulic chlorinated, ka wai hydraulic non-flammable, ka ʻelemakule, nā ʻakika ikaika, ka wai haki, acetone, halogenated hydrocarbons, vacuum a me ka hapa nui o nā waikawa.
