393000M024 Excavator hydraulic pump solenoid valve proportional solenoid valve 3768317

ʻO ka ʻokoʻa ma waena o ka valve proportional electric a me ka valve solenoid

Hiki ke hoʻokaʻawale ʻia ka mana o ka valve i ʻelua ʻano:
 

Hoʻokahi ka mana hoʻololi: ʻo ka wehe piha a i ʻole ka pani piha ʻana, ʻoi aku ka nui a i ʻole ka liʻiliʻi o ke kahe, ʻaʻohe kūlana waena, e like me ka electromagnetic maʻamau ma o ka valve, electromagnetic reversing valve, electro-hydraulic reversing valve. ʻO ka mea ʻē aʻe ka hoʻomau mau ʻana: hiki ke wehe ʻia ke awa valve e like me ka pono o kēlā me kēia degere o ka wehe ʻana, a laila e kāohi ana i ka nui o ke kahe ʻana, ʻo ia mau valve ka mana lima, e like me nā throttle valves, akā hoʻokele uila ʻia, e like me ka proportional. kiwikā, servo valves. No laila ke kumu o ka hoʻohana ʻana i ka valve proportional a i ʻole servo valve ʻo ia: e hoʻokō i ka mana kahe e ka mana uila (ʻoiaʻiʻo, ma hope o ka hoʻololi ʻana o ka hoʻololi ʻana hiki ke hoʻokō i ka mana kaomi, a me nā mea ʻē aʻe), ʻoiai ʻo ia ka mana throttling, pono e nalowale ka ikehu, servo ʻOkoʻa ka valve a me nā kīwī ʻē aʻe, ʻoi aku ka nui o kona nalowale o ka ikehu, no ka mea, pono ia i kahi kahe e mālama ai i ka hana o ka ʻaila kaapuni mua.
ʻO ka valve electromagnetic (Electromagnetic valve) ka hoʻohana ʻana i ka electromagnetic

ʻO ka loina hana o ka valve solenoid proportional
   

Electro-hydraulic proportional valve ka proportional electromagnet input voltage signal in the valve e hana i ka hana like, no laila ka neʻe ʻana o ka valve spool displacement, hoʻololi ka nui o ka valve port a hoʻopau i ke kaomi a me nā mea hoʻokahe kahe 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.
