Excavator hydraulic pump solenoid valve proportional solenoid valve TM82002

ʻO ka holomua ʻenehana o nā valves electro-hydraulic proportional valves a me nā ʻāpana kūikawā ʻē aʻe o ka mīkini ʻenekinia e hana i ka mana uila o nā ʻōnaehana like ʻole e like me ke kaʻa, hoʻokele, braking a me nā mea hana o nā kaʻa ʻenekinia i lilo i mea maoli. No ka mīkini e koi maʻamau i ka hoʻokuʻu ʻana, hiki ke hoʻohana ʻia ka proportional servo control manual multiway valve driver e like me ke Kiʻi 1 e hoʻopau. Loaʻa ka maikaʻi o ka hana uila i ka pane wikiwiki, ka wili maʻalahi, ka mana hoʻohui a me ka maʻalahi o ka maʻalahi me ka kamepiula, no laila ua ʻoi aku ka nui o ka hoʻohana ʻana i nā ʻenekini hydraulic hydraulic hou i ka hoʻohana ʻana i nā pahu uila electro-hydraulic proportional valve (a i ʻole electro-hydraulic switch). nā valves) ma kahi o ka hana pololei manual a i ʻole ka hydraulic pilot controlled multi-way valves. ʻO kekahi mea maikaʻi ʻē aʻe o ka hoʻohana ʻana i nā valves electro-hydraulic proportional valves (a i ʻole electro-hydraulic on-off valves) ʻo ia ka mea hiki ke hoʻemi nui ʻia ka nui o nā lima hana i nā kaʻa ʻenekinia, ʻaʻole ia e maʻalahi ka hoʻolālā kaʻa, akā e hōʻemi pono i ka paʻakikī. o ka hana, he koʻikoʻi koʻikoʻi koʻikoʻi no ka hoʻomaikaʻi ʻana i ka maikaʻi a me ka pono o ka hana. ʻO ka Figure 2 ka lever control TECNORD JMF (joystick), me ka hoʻohana ʻana i ka hauʻoli e hiki ke hoʻomalu pono i ka ʻāpana electro-hydraulic proportional valve a me ka valve on-off i ke Kiʻi 2. Hiki i ka rocker ke hoʻomaopopo i ka mana proportional a i ʻole ka mana hoʻololi ma X a me Y. kuhikuhi axis, a maʻalahi loa ka noi.
