Hitachi excavator amafukula zopanda mphamvu kukonza zolakwika
Pampu ya hydraulic ya Hitachi excavator ndi plunger variable pump. Mukamagwira ntchito kwa nthawi yayitali, zigawo za pampu ya hydraulic, monga cylinder block, plunger, valve plate, swing, ndi zina zotero, zidzatulutsa kuvala kwambiri, zomwe zimachititsa kuti kuchulukira kwamkati kuchuluke komanso deta yosagwirizana. , zomwe zimapangitsa kuyenda kosakwanira komanso kutentha kwakukulu kwa mafuta, kuthamanga kwapang'onopang'ono, komanso kulephera kukhazikitsa kuthamanga kwakukulu, kotero kuti ntchitoyo imachedwa ndipo kukumba kumakhala kofooka. Pazovuta zotere, ndikofunikira kuchotsa pampu ya hydraulic, kuitumiza ku dipatimenti yowonongeka, kuyesa deta yapampu ya hydraulic, kutsimikizira vuto la chofukula, m'malo mwa zigawo zomwe sizingagwiritsidwe ntchito, kukonza magawo omwe angagwiritsidwe ntchito. , phatikizaninso pampu ya hydraulic, kenako pitani ku benchi yoyeserera kuti mufanane ndi magawo osiyanasiyana ofewa (monga kuthamanga, kuthamanga, torque, mphamvu, etc.).

Hitachi excavator hydraulic original multi-way distribution valve valve yokonza valavu yogawa njira zambiri pamwamba pa valavu yaikulu yachitetezo, valavu yachiwiri, valavu ya ndege, valavu yamafuta ndi zina zotero. Ngati ma valve otetezerawa sakukhazikitsidwa pakalipano (kuthamanga kwa EX200-5 valavu yaikulu ya chitetezo ndi 320kg, koma kupanikizika kwaposachedwa ndi 230kg), kufukula kudzakhala kofooka. Kuonjezera apo, ngati kusiyana pakati pa tsinde la valve ndi dzenje la valve ndi lalikulu kwambiri chifukwa cha kuvala, kubwereza kwa tsinde la valve sikokwanira, zomwe zimapangitsa kuyenda kosakwanira komanso kuthamanga pang'onopang'ono. Pazovuta zotere, ndikofunikira kuchotsa valavu yogawa mitundu yambiri, kuitumiza ku kampaniyo molunjika pa nsanja yochotsa zolakwika, kukonzanso kukakamiza kwa ma valve onse otetezera, ndikuchotsa kusiyana pakati pa tsinde la valve ndi dzenje la valve.
