ʻO TM70301 kūpono solenoid valve hydraulic pump excavator accessories

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 maʻalahi o ka hoʻohana ʻana i ka pahu pahu pahu, ka mālama paipu a me ka hoʻokumu lāʻau haʻahaʻa, a me nā mea ʻē aʻe.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;ʻEkolu loulou
ʻO ka valve proportional ka pahu hoʻohaʻahaʻa hoʻohaʻahaʻa proportional 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 ke hoʻololi i ka valve hoʻemi hoʻohaʻahaʻa hoʻohaʻahaʻa ʻekolu ʻaoʻao i ka valve pilote hoʻohaʻahaʻa lima maʻamau, ʻoi aku ka maʻalahi a ʻoi aku ka maikaʻi o ka mana ma mua o ka valve pilot manual.Hiki ke hana ia i loko o ka servo control manual multi-way valve e like me ka mea i hōʻike ʻia ma ka Figure 1. Me nā hōʻailona hoʻokomo ʻokoʻa, ʻo ke kaomi hoʻohaʻahaʻa hoʻohaʻahaʻa e hana i ka piston puka i ke kaomi ʻokoʻa a i ʻole ka kahe kahe e hoʻokō i ka mana proportional o ka neʻe ʻana o ka multi- ala pahu pahu.Hiki ke ho'omalu pakahi 'ia nā pahu pahu pahu pahu he nui ala no ka mea hana.
ʻO ka paheʻe valve type proportional valve, i ʻike ʻia ʻo ka valve distribution, ʻo ia kekahi o nā mea maʻamau o ka ʻōnaehana hydraulic mechanical mobile, hiki ke ʻike i ke kuhikuhi a me ke kahe ʻana o ka valve composite.
ʻO Electro-hydraulic slide valve proportional multiway valve he mea kūpono loa ka electro-hydraulic conversion control element, mālama ia i ka hana maʻamau o ka manual multiway valve, akā hoʻonui pū i ke kūlana o ka hana servo proportional feedback a me ka load sensing a me nā ala ʻē aʻe. ʻo ia ka mīkini hana hoʻokaʻawale ʻana i nā huahana pani pani.
Ma muli o ka noʻonoʻo ʻana i nā kumukūʻai hana a me nā koi ʻana i ka pololei o ka mīkini hana ʻana ʻaʻole ia he mau hiʻohiʻona kiʻekiʻe, ʻaʻole i hoʻolako ʻia ka valve multi-way proportional maʻamau me ka sensor displacement, me ka ʻike uila a me nā hana hoʻoponopono hewa.Hoʻopili maʻalahi ka neʻe ʻana o ka spool e nā loli kaomi i hoʻololi ʻia e ka hoʻololi ʻana, a koi ʻia ka nānā ʻana e hōʻoia i ka pau ʻana o ka hana i ka wā o ka hana.ʻO ka mana uila, ka hana hoʻomalu mamao pono e uku nui aku i ka mana o ke keakea o waho.I kēia mau lā, me ka hoʻomohala ʻana o ka ʻenehana uila, ke hoʻohana nei ka poʻe i ka nui a me ka ʻoi aku o ka hoʻopili kūloko
Hoʻohana ʻia nā mea ʻike hoʻoneʻe e like me ka dynamic transformer (LDVT) e ʻike i ka neʻe ʻana o ke kūlana spool a ʻike i ka mana pani pani o ka neʻe ʻana o ka spool.ʻO kēia valve proportional i hoʻohui pū ʻia me kahi valve solenoid proportional valve, kahi sensor manaʻo kūlana, kahi hoʻonui hoʻokele a me nā kaʻa uila ʻē aʻe.
