ʻO Excavator EX200-5 ka pahu hoʻomaha hoʻomaha wai hydraulic YA00011313

ʻEli ʻo Hitachi excavator i ka hoʻoponopono hewa ʻole
ʻO ka paila hydraulic o Hitachi excavator he plunger variable pump. I ka hana ʻana no kekahi manawa, ʻo nā mea i loko o ka pā hydraulic, e like me ka cylinder block, plunger, valve plate, swing, etc., e hoʻopuka i ka lole nui, e hopena i ka nui o ka leakage kūloko a me ka ʻike ʻike ʻole. , ka hopena i ka lawaʻole o ke kahe a me ke kiʻekiʻe o ka aila wela, ka wikiwiki wikiwiki, a me ka hikiʻole ke hoʻokumu i ke kaomi kiʻekiʻe, no laila ua lohi ka hana a ua nāwaliwali kaʻeliʻana. No ia mau pilikia, pono e wehe i ka pauma hydraulic, e hoʻouna i ke keʻena debugging, e hoʻāʻo i ka ʻikepili hydraulic pump, e hōʻoia i ka pilikia o ka excavator, e hoʻololi i nā ʻāpana hiki ʻole ke hoʻohana hou, hoʻoponopono i nā ʻāpana hiki ke hoʻohana. , e hui hou i ka paila hydraulic, a laila e hele i ka papa ho'āʻo debugging e hoʻohālikelike i nā ʻano like ʻole o nā ʻāpana palupalu (e like me ke kaomi, kahe, torque, mana, etc.).

ʻO Hitachi excavator hydraulic original multi-way distribution valve ka mālama ʻana i nā ʻāpana hoʻohele lehulehu ma luna o ka valve palekana nui, ka lua lua, ka jet valve, ka ʻaila ʻaila a pēlā aku. Inā ʻaʻole i hoʻonohonoho ʻia kēia mau pahu palekana i kēia manawa i ke kaomi maʻamau (ʻo ke kaomi maʻamau o ka pahu palekana nui EX200-5 he 320kg, akā ʻo 230kg wale nō ke kaomi o kēia manawa), e nāwaliwali ka ʻeli ʻana. Eia kekahi, inā ʻoi aku ka nui o ka ʻāpana ma waena o ke kumu valve a me ka lua valve ma muli o ka ʻaʻahu ʻana, ʻaʻole i pau ka hoʻihoʻi ʻana o ka pahu valve, e hopena i ka lawa ʻole a me ka wikiwiki wikiwiki. No ia mau pilikia, pono ia e wehe i ka pahu hoʻolaha multi-way, e hoʻouna pololei iā ia i ka hui ma luna o ke kahua hoʻoheheʻe no ka debugging, hoʻihoʻi hou i ke kaomi o nā pahu palekana āpau, a hoʻopau i ke āpau ma waena o ke kumu valve a me ka lua valve.
