Pehea e koho ai i ke apo sealing no ka ʻōnaehana hydraulic?
1. NBR nitrile rubber sealing apo ua kūpono ia no ka hoʻohana ʻana i ka ʻaila hydraulic petroleum, ethylene glycol hydraulic oil, diester lubricating oil, gasoline, wai, silicone grease, silicone oil and other media.ʻO ia ka mea hoʻohana nui loa a haʻahaʻa loa ke kumu kūʻai.ʻAʻole kūpono no ka hoʻohana ʻana i nā solvents polar e like me ketones, ozone, nitrohydrocarbons, MEK a me chloroform.ʻO ka pae wela hoʻohana maʻamau -40 ~ 120 ℃.ʻO ka lua, ʻo ka HNBR hydrogenated nitrile rubber sealing apo he maikaʻi ke kūpaʻa corrosion, ke kū ʻana o ka waimaka a me nā ʻano deformation compression, ka pale ʻana o ka ozone, ka pale ʻana o ka lā, ka maikaʻi o ka wā.ʻOi aku ka maikaʻi o ka pale ʻana ma mua o ka nitrile rubber.He kūpono no ka mīkini holoi, ʻōnaehana ʻenekini kaʻa a me nā ʻōnaehana hoʻoheheʻe me ka hoʻohana ʻana i ka mea hoʻoheheʻe kaiapuni hou R134a.ʻAʻole ʻōlelo ʻia no ka hoʻohana ʻana i nā ʻawaʻawa, nā esters, a i ʻole nā mea ʻala.ʻO ka pae wela hoʻohana maʻamau -40 ~ 150 ℃.ʻO ke kolu, ʻo FLS fluorine silicone rubber sealing apo i nā mea maikaʻi o ka fluorine rubber a me ka silicone rubber, ka aila kūpaʻa, ka pale ʻana i ka solvent, ke kūpaʻa ʻaila a me ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa.He kūpaʻa ia i ka hoʻouka ʻana o ka oxygen i loko o nā pūhui, hydrocarbon aromatic i loaʻa nā solvents a me ka chlorine i loko o nā mea hoʻoheheʻe.Hoʻohana maʻamau ia no ka mokulele, aerospace a me nā kumu koa.ʻAʻole ʻōlelo ʻia ka ʻike ʻana i nā ketones a me nā wai hoʻomaha.ʻO ka pae wela hoʻohana maʻamau -50 ~ 200 ℃.
2, ma waho aʻe o nā koi maʻamau o ke apo sealing material, pono e hoʻolohe ke apo sealing i nā kūlana aʻe: (1) elastic a resilient;(2) ʻO ka ikaika mechanical kūpono, me ka ikaika hoʻonui, elongation a me ka ikaika o ka waimaka.(3) Paʻa ka hana, ʻaʻole maʻalahi ka pehu ma ka waena, a liʻiliʻi ka hopena hoʻoneʻe wela (Joule effect).(4) E maʻalahi ka hana a me ke ʻano, a hiki ke mālama i ka nui pololei.(5) ʻaʻole ia e ʻino i ka ʻili pili, ʻaʻole e hoʻohaumia i ka waena, a me nā mea ʻē aʻe.Nui nā ʻano o ka lāʻau lapaʻau, a loaʻa mau nā ʻano lāʻau lapaʻau hou, ka hoʻolālā a me ke koho ʻana, pono e hoʻomaopopo i nā ʻano o nā ʻāpana like ʻole, koho kūpono.
3. Pono
(1) Pono ke apo sealing e hoʻokō maikaʻi i ka hana hoʻopaʻa ʻana i ke kaomi hana a me kahi pae wela, a hiki ke hoʻomaikaʻi ʻokoʻa i ka hana sealing me ka piʻi ʻana o ke kaomi.
(2) Pono e liʻiliʻi ka friction ma waena o ke apo apo a me nā ʻāpana neʻe, a paʻa ka coefficient o ka friction.
(3) ʻO ke apo sealing he ikaika ka corrosion resistance, ʻaʻole maʻalahi i ka makahiki, lōʻihi ke ola hana, ke kūpaʻa maikaʻi ʻana, a hiki ke uku ʻia ma hope o ka hoʻohana ʻana i kekahi ʻano.
(4) He hana maʻalahi, maʻalahi e hoʻohana a mālama, i ʻoi aku ka lōʻihi o ke ola o ke apo sealing.ʻO ka pōʻino o ke apo sila e hoʻoulu ai i ka leakage, ka hopena o ka pau ʻana o ka media hana, ka haumia o ka mīkini a me ke kaiapuni, a hiki i ke kumu o ka hana ʻole ʻana o ka hana mechanical a me nā ulia pilikino.ʻO ka leaka o loko e hoʻohaʻahaʻa loa i ka pono volumetric o ka ʻōnaehana hydraulic, a ʻaʻole hiki ke hoʻokō ʻia ke kaomi hana i koi ʻia, a ʻaʻole hiki ke hoʻokō ʻia ka hana.Hiki i nā ʻāpana lepo liʻiliʻi e hoʻouka i ka ʻōnaehana hiki ke hoʻoulu a hoʻonui paha i ka ʻaʻahu ʻana o nā paʻa paʻa o nā ʻāpana hydraulic, e alakaʻi hou ana i nā leaka.No laila, ʻo nā sila a me nā mea hoʻopaʻa paʻa he mea nui o nā mea hydraulic.ʻO ka hilinaʻi a me ke ola lawelawe o kāna hana he hōʻailona koʻikoʻi ia e ana i ka maikaʻi o ka ʻōnaehana hydraulic.
Hoʻokumu ʻo Zhuo Meng Shanghai Auto Co., Ltd. e kūʻai aku i nā ʻāpana kaʻa MG&MAUXS e hoʻokipa ʻia e kūʻai.
