Hana ʻole ʻia e ka valve palekana
Poha ka paipu hydraulic, piʻo ka lever cylinder. ʻO ke kumu nui ʻo ia ka hoʻoponopono ʻana i ka valve palekana, a me kekahi mau hoa eli i mea e hoʻomaikaʻi ai i ka hana holoʻokoʻa o ka excavator, hoʻoponopono i ka waiwai hoʻonohonoho kaomi o ka pahu kōkua nui a me ka valve palekana e hoʻonui i ka ikaika o ka excavator. Eia nō naʻe, i ka hana ʻana, ma lalo o ka hana kiʻekiʻe kiʻekiʻe o ka excavator, e piʻi aʻe ka nui o ka puʻu wai hydraulic, a ʻo ka cylinder lever e kūlou no ka mea ʻaʻole hiki iā ia ke pale i ke kaomi nui.
Ma muli o ka hāʻule ʻole o ka valve palekana, ua paʻa ka spool, a i ʻole ke kāohi ʻia ka ʻaila ma ke awa overflow, kahi e alakaʻi ai i ka haʻahaʻa haʻahaʻa, e pili ana i kekahi mau hana, lawa ʻole ka mana, a me ka hana lohi. I kēia manawa, e hoʻoponopono kekahi mau hoa ʻeli i ke kaomi o ka pahu hoʻomaha nui, a ʻaʻole e piʻi ke kaomi hoʻoponopono. ʻO ke kumu o ka hāʻule ʻana he pilikia paha me ka valve palekana, no laila e nānā koke ʻia ka valve palekana.
No ka mea ʻaʻole pili pono ka hana o ka excavator i ka hana maʻamau e ka valve palekana, ʻike pinepine ʻia ka valve palekana i ka excavator. Ma kēia hoʻomanaʻo, i ke kaʻina hana mālama o ka excavator, pono e hoʻomanaʻo i ka valve palekana e nānā, i ka manawa i ʻike ʻia ai ka pahu palekana i ka lole a me nā hewa ʻē aʻe, pono e hoʻololi ʻia me kahi valve palekana hou i ka manawa.
