He kūpono no Volvo proportional rotary solenoid valve 23871482

Electromagnetic proportional valve hana kumu a me ka ʻike:
Hiki ke hoʻokaʻawale ʻia ka mana o ka valve i ʻelua ʻano:
Hoʻokahi ka mana o ka hoʻololi: ʻo ka wehe piha ʻana a i ʻole ka pani piha ʻana, ʻo ka nui a i ʻole ka liʻiliʻi o ke kahe, ʻaʻohe kūlana waena, e like me ka electromagnetic maʻamau ma o nā kīwaha, nā kiwi hoʻohuli electromagnetic, nā kiwi hoʻohuli electro-hydraulic.
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 nui o ka valve servo ka mea maʻamau e like me ka reversing valve he slide valve structure, akā ʻo ka hoʻohuli ʻana o ka valve core ʻaʻole i alakaʻi ʻia e kahi electromagnet, akā e ka hydraulic pressure output o ka pre-stage valve, ʻo ia. ʻoi aku ka like me ka valve reversing electro-hydraulic, akā ʻo ka valve pre-stage o ka electro-hydraulic reversing valve he solenoid reversing valve, a ʻo ka valve pre-stage o ka servo valve he nozzle baffle valve a i ʻole jet pipe valve me ka maikaʻi. nā hiʻohiʻona ikaika.
