ʻO ka pauma Hydraulic proportional solenoid valve 25223075 excavator

ʻO ka valve electro-hydraulic proportional valve ka proportional electromagnet input voltage signal i loko o ka valve e hana i ka hana like, i hiki ai i ka valve spool displacement, valve
Hoʻololi ʻia ka nui o ke awa e hoʻopau i ke kaomi, kahe ʻana o ka mea hoʻopuka e like me ka volta komo. Hiki ke hoʻihoʻi ʻia ka hoʻoneʻe ʻana o ka spool me ka mechanically, hydraulically a i ʻole uila. Electro-hydraulic proportional valve he ʻano ʻano like ʻole, maʻalahi e hoʻohana i ka uila a me ka mana kamepiula o nā ʻōnaehana electro-hydraulic like ʻole, ka pololei o ka mana kiʻekiʻe, ka hoʻokomo ʻana a me ka hoʻohana ʻana, a me ka mana anti-pollution ikaika, a me nā pono ʻē aʻe, ke hoʻonui nei ke kahua noi. . I nā makahiki i hala iho nei, ʻo ka hoʻomohala ʻana a me ka hana ʻana o nā valve proportional plug-in a me nā valve multiway proportional e noʻonoʻo pono i nā hiʻohiʻona o nā mīkini hana, me ka hoʻokele pilote, ka ʻike ukana a me nā hana uku. He mea nui ia e hoʻomaikaʻi i ka pae ʻenehana holoʻokoʻa o ka mīkini hydraulic mobile. ʻO ka mea nui, ua hōʻike ʻia ka hana hoʻokele uila uila, ka mana mamao uea a me ka hana hoʻokele mamao uea i nā manaʻo noi maikaʻi.
2 ʻO nā ʻano a me nā ʻano o nā kiwi hoʻohālikelike electro-hydraulic no ka mīkini hana ʻia ʻo Electro-hydraulic proportional valves e pili ana i nā kiwi hoʻoheheʻe like ʻole, nā kiwi puʻe kaulike a me nā kiwi kuhikuhi kuhikuhi. ʻO nā hiʻohiʻona hana hydraulic mīkini hana, ua māhele ʻia i ʻelua mau ʻano o ka valve electro-hydraulic proportional valve i ke ʻano o ke ʻano o ka hoʻolālā: ʻo kekahi ʻo ka pahu pahu spiral type proportional valve, ʻo kekahi ʻo ka slide valve type proportional valve ʻO nā ʻāpana i hoʻopaʻa ʻia ma ka ʻaila kaapuni i hoʻohui ʻia i nā ʻāpana, ʻo ka valve cartridge spiral nā hiʻohiʻona o ka noi maʻalahi, mālama paipu a me nā kumu kūʻai haʻahaʻa, etc.
Hoʻohana nui a hoʻohana nui ʻia. Hoʻohana maʻamau ʻia ka puʻupuʻu puʻupuʻu like ʻole ʻelua, ʻekolu, ʻehā a me nā ʻano multi-pass, ʻelua ʻaoʻao proportional valve main proportional throttle valve, ʻo ia ka mea pinepine i kona mau ʻāpana e hoʻokumu i kahi puʻupuʻu composite, ka kahe, ka mana kaomi;
