E330C pahu hoʻomaha nui 103-8177 Excavator mea hoʻohui i ka solenoid valve

ʻO nā ʻano a me nā ʻano o nā kiwi hoʻohālikelike electro-hydraulic no nā mīkini hana
Electro-hydraulic proportional valves proportional flow valves proportional pressure valves proportional pressure valves proportional directional valves. Hoʻokaʻawale ʻia nā hiʻohiʻona hana hydraulic o nā mīkini hana i ʻelua mau ʻano o nā valves electro-hydraulic proportional valves i ke ʻano o ka hoʻolālā: ʻo kekahi he spiral cartridge proportional valves, a ʻo kekahi he slide valve proportional valve.
ʻO ka pahu pahu hoʻohālikelike hoʻopaʻa ʻia ʻo ia ka mea i hoʻopaʻa ʻia ma ka poloka hui kaapuni ʻaila. Loaʻa nā hiʻohiʻona o ka hoʻohana ʻana i ka hoʻohana maʻalahi, ka mālama ʻana i ka paipu a me ke kumukūʻai haʻahaʻa, a ua hoʻohana nui ʻia i nā mīkini hana i nā makahiki i hala.
Nui. 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; ratio ʻekolu ala
ʻO ka pahu hoʻohaʻahaʻa hoʻohaʻahaʻa hoʻohālikelike nui ʻo ia hoʻi ka valve proportional i hoʻohana nui ʻia i ka ʻōnaehana hydraulic mechanical mobile, ka mea e hana nui i ka hydraulic multiway valve pilot oil circuit. Hiki i ka hoʻohana ʻana i ka valve hoʻemi hoʻohaʻahaʻa ʻekolu ala ke hoʻololi i ka decompression manual maʻamau ma mua
Pilot valve, ʻoi aku ka maʻalahi a ʻoi aku ka pololei o ka mana ma mua o ka valve pilot manual. Hiki ke hana ʻia i loko o ka servo control manual multi-way valve e like me ka mea i hōʻike ʻia ma ka Figure 1. ʻO nā hōʻailona hoʻokomo ʻokoʻa, ʻo ke kaomi hoʻohaʻahaʻa hoʻohaʻahaʻa e hana i ka piston puka i ke kaomi ʻokoʻa a kahe paha.
A laila ʻike ʻo ia i ka mana proportional o ka neʻe ʻana o ka spool valve multi-way. Hiki ke ho'omalu pakahi 'ia ka pahu pahu pahu pahu he nui ala no ka mea hana.
