ʻO ka pauma Hydraulic solenoid valve excavator loader lako 207-6809

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 i loko o ka valve e hana i ka hana like, no laila ka neʻe ʻana o ka valve spool, ka lula waha valve.
Hoʻololi ka ʻīniha a pēlā e hoʻopau ai i ke kaomi, kahe ʻana o ka mea hoʻopuka e like me ka volta komo. Hiki ke hoʻoneʻe ʻia ka spool ma mechanical, hydraulic a i ʻole
ʻAno uila no ka manaʻo. Loaʻa nā ʻano ʻano like ʻole o ka valve proportional electro-hydraulic, maʻalahi e hana i ka hoʻohana ʻana i ka uila a me ka mana kamepiula o nā ʻōnaehana electro-hydraulic.ʻO ka ʻōnaehana, ka pololei o ka mana kiʻekiʻe, ka hoʻokomo ʻana a me ka hoʻohana ʻana, ka ikaika anti-pollution ikaika a me nā pono ʻē aʻe, ke hoʻonui nei ke kahua noi i kēlā me kēia lā. Ka noiʻi a me ka hoʻomohala houʻO ka hana ʻana o nā valves proportional plug-in a me nā valves proportional multi-way valves e noʻonoʻo pono i nā ʻano o ka hoʻohana ʻana i nā mīkini hana, me ka mana hoʻokele, ka ʻike ukana a me ke kaomi.Ka uku a me nā hana ʻē aʻe. He mea nui ia e hoʻomaikaʻi i ka pae ʻenehana holoʻokoʻa o ka mīkini hydraulic mobile. ʻOi aku ka hana hoʻokele uila i hoʻomalu ʻia,Ua hōʻike ʻia kahi manaʻo noiʻi maikaʻi i ka mana mamao uea a me ka hoʻokele mamao uea.
