ʻO ke kumu o ka hydraulichoʻoheheʻe ʻia o ka cylinderpono e hoʻopaʻa ʻia ma muli o ka loaʻa ʻana o ka leaka kūloko a me waho leakage. Ke loaʻa ka leakage o loko a me ka hoʻokuʻu waho i ka hydraulic cylinder, e alakaʻi ia i ka nui o ka lua o ka hydraulic cylinder a e liʻiliʻi ka pono a e hoʻemi ʻia ka hana o ka hydraulic cylinder i ka hana. Ke koʻikoʻi ke kūlana, ʻaʻole hiki i ka ʻōnaehana ke hana ma lalo o ke kaomi. I ka manawa like, mai ka hiʻohiʻona o ka mālama ʻana i ke kaiapuni, pono e pale ʻia ka leakage e like me ka hiki, no laila he mea nui e lawe i nā hana hoʻopaʻa.

ʻO nā ʻāpana hoʻopaʻa nui i ka cylinder hydraulic he piston, piston rod, uhi hopena a pēlā aku. A ʻekolu mau ala e hoʻopaʻa ai i ka cylinder hydraulic. I kēia lā, e hoʻolauna ʻo Jiuli i nā ala ʻekolu o ka hoʻopaʻa ʻana i ka cylinder hydraulic:

ʻO ka mua, ka hoʻopaʻa ʻana i ka sila

ʻO kāna kumu hana ʻo ia ka liʻiliʻi ma waena o nā ʻāpana neʻe ʻelua, a ʻo ke kūpaʻa ʻana o ka friction wai i hana ʻia i loko o ke āpau e pale i ka leakage. Aia kekahi mau hemahema o kēia ʻano, pili wale ia i ka cylinder hydraulic liʻiliʻi a me ke anawaena piston a me ke kaomi ma waena o ke sila a me ka pōmaikaʻi i mea e hoʻomaikaʻi ai i ka pono o ka sila e waiho i kekahi mau puʻupuʻu ma ka piston, e ʻae ka groove i ka hoʻololi o ka ʻaila i loko. leakage ala a oki paha, i loko o ka liʻiliʻi groove hana vortex a hana kū'ē, a hoemi i ka aila leakage; Ma ka lima ʻē aʻe, pale ia i ka offset o ka piston axis, ka mea e kūpono i ka mālama ʻana i ka hoʻomaʻemaʻe kūpono, e hōʻoia i ka hopena lubrication, e hōʻemi i ka ʻaʻahu o ka piston a me ka paia cylinder, a me ka hoʻonui ʻana i ka hana sealing clearance.

ʻElua, ka hoʻohana ʻana i ke apo sealing rubber

Ma muli o nā ʻano like ʻole o nā apo sealing i ka hydraulichoʻoheheʻe ʻia o ka cylinder, ʻAʻole like ka mīkini hoʻopaʻa ʻana i hoʻohana ʻia, a hilinaʻi nui ke apo sealing O-type i ka nui o ka pre-compression e hoʻopau i ke āpau e hoʻokō i ka hopena sealing. Aʻo Y, YX, V shape, etc., hilinaʻi ma ka sealing apo lehelehe deformation ma ka hana o ka wai kaomi, i ka lehelehe kokoke i ka sila ili a sila, oi aku ka kiʻekiʻe o ka wai kaomi, o ka oi paʻa o ka lehelehe lāʻau. a loaʻa iā ia ka mana o ka uku ʻakomi ma hope o ke komo ʻana.

ʻEkolu, ʻo ka hoʻohana ʻana i nā ʻāpana sealing rubber e hoʻokō i ka hopena sealing

ʻO kēia ʻano sila he ʻano hui pū me nā hiʻohiʻona o nā ʻano sila ʻelua, e pāʻani pū ana i kahi hana sila i ka hana. E lawe i ke apo hina, ʻo ia hoʻi ka hui pū ʻana o ke apo O-ringe a me ke apo hina teflon. I ka hana, i ka elasticity maikaʻi o O-type rubber apo produces pre-a me ka hoʻomaʻemaʻe ponoʻī, i hiki ke hoʻohana 'ia i loko o ka hydraulic cylinder seal lōʻihi ola.

ʻO ka mea i luna nei ke ala hoʻopaʻa kikoʻī o ka cylinder hydraulic, manaʻolana wau e kōkua ia iā ʻoe.
