1. ʻO nā ʻano nui o ka pōʻino piston:
(1) Nā ʻōpala o ka ʻili;
(2) Ua haki ka piston;
(3) Loaʻa nā māwae a me ka ʻoki ʻana
2. He aha nā kumu o ka pōʻino piston?
(1) ʻAʻole maʻemaʻe ka ʻaila hydraulic
Inā hui pū ʻia ka ʻaila me nā mea haumia, i ka manawa e komo ai kēia mau mea haumia i ke āpau ma waena o ka piston a me ka cylinder, e hoʻopiʻi ia i ka piston. ʻO ke kānana i hoʻokumu ʻia i kēia hihia he mau hiʻohiʻona kēia: maʻamau e loaʻa nā grooves me ka hohonu o ʻoi aku ma mua o 0.1mm, a liʻiliʻi ka helu, a ua like ka lōʻihi me ka hahau o ka piston. Paipai ʻia nā mea kūʻai aku e nānā mau a hoʻololi i ka ʻaila hydraulic o ka excavator
(2) He liʻiliʻi loa ke āpau ma waena o ka piston a me ka cylinder
Hiki pinepine kēia kūlana ke hoʻololi ʻia kahi piston hou. Inā liʻiliʻi loa ka ʻokoʻa ma waena o ka piston a me ka cylinder, hiki ke maʻalahi ke hoʻoulu ʻia i ka wā e hoʻololi ai ke āpau i ka piʻi ʻana o ka mahana o ka aila i ka wā e hana ai. ʻO kāna mau hiʻohiʻona hoʻoholo: he pāpaʻu ka hohonu o ka māka huki, nui ka ʻāpana, a ua like kona lōʻihi me ka hahau ʻana o ka piston. Manaʻo ʻia ka mea kūʻai aku e ʻimi i kahi haku loea e pani ai, a ʻo ka ʻae ʻana i loko o kahi ākea kūpono
(3) He haʻahaʻa ka paʻakikī o ka piston a me ka cylinder
Hoʻopili ʻia ka piston i ka ikaika o waho i ka wā o ka neʻe ʻana, a haʻahaʻa ka paʻakikī o ka ʻili o ka piston a me ka cylinder, kahi e hoʻopaʻa ai. ʻO kona mau hiʻohiʻona: ka hohonu pāpaʻu a me kahi ākea nui
(4) ʻAʻole pono ka ʻōnaehana lubrication
Ua hewa ka ʻōnaehana hoʻoheheʻe hydraulic breaker piston, ʻaʻole lawa ka lubricated o ke apo piston, a ʻaʻohe kiʻi ʻaila pale i hoʻokumu ʻia, e hopena i ka friction maloʻo, kahi e haki ai ke apo piston hydraulic breaker.
inā poino ka piston, e ʻoluʻolu e hoʻololi koke me kahi piston hou.
