Hiki ke hoʻohana ʻia ʻo USI no nā piston a me nā sila lāʻau.He ʻāpana liʻiliʻi kēia packing a hiki ke hoʻokomo ʻia i loko o ke awāwa i hoʻohui ʻia.
He lehelehe lehelehe ʻo YA i hiki ke hoʻohana ʻia no ke koʻokoʻo a me ka piston, kūpono ia no nā ʻano ʻaila ʻaila a pau, e like me ka forging press hydraulic cylinders, nā pahu kaʻa mahiʻai.
Hoʻohana ʻia ke ʻano o ka sila UPH no nā piston a me nā sila lāʻau.ʻO kēia ʻano sila he ʻāpana keʻa nui a hiki ke hoʻohana ʻia no ka nui o nā hana.Hōʻoiaʻiʻo ʻo Nitrile rubber material i kahi ākea ākea ākea a me kahi ākea o ka noi.
Ma muli o ka hoʻohana nui ʻia ʻana i nā cylinders hydraulic, hiki ke hoʻohana ʻia ʻo USH no ka piston a me ke koʻokoʻo noi no ka loaʻa ʻana o ke kiʻekiʻe like o nā lehelehe sila ʻelua.Hoʻohālikelike ʻia me ka mea o NBR 85 Shore A, ʻo USH kekahi mea ʻē aʻe ʻo Viton/FKM.
ʻO ka UNS/UN Piston Rod Seal he ʻaoʻao ākea ākea a he apo hoʻopaʻa u-shaped asymmetrical me ke kiʻekiʻe like o nā lehelehe i loko a me waho.He mea maʻalahi ke komo i loko o kahi hale monolithic.Ma muli o ka ʻāpana ākea ākea, hoʻohana ʻia ʻo UNS Piston Rod Seal i kahi cylinder hydraulic me ka haʻahaʻa haʻahaʻa. kaulike.
