Oyenera excavator PC200-6 hydraulic relief valve 702-75-01200

Electro-hydraulic proportional valve ndi solenoid proportional mu valavu molingana ndi cholumikizira voteji kuti apange chinthu chofananira, kuti valavu yogwira ntchito, kusintha kwa doko la valavu ndikumaliza kukakamiza ndi kutuluka molingana ndi magawo amagetsi olowera, Kusuntha kwa valve spool kumathanso kukhala ngati makina, ma hydraulic kapena mayankho amagetsi. Chifukwa valavu ya electro-hydraulic proportional valve ili ndi mitundu yosiyanasiyana, yosavuta kupanga mitundu yosiyanasiyana ya magetsi ndi makompyuta oyendetsedwa ndi ma electro-hydraulic systems, kulondola kwapamwamba, kusinthika ndi kugwiritsira ntchito, komanso mphamvu zotsutsana ndi zowonongeka, malo ogwiritsira ntchito akuwonjezeka. M'zaka zaposachedwa, valavu ya pulagi-mu proportional ndi valavu yofananira ya multiway yapangidwa ndikupangidwa kuti iganizire mozama za kagwiritsidwe ntchito ka makina omanga. Imakhala ndi ntchito zowongolera oyendetsa ndege, kuzindikira katundu ndi kubweza kukakamizidwa, ndipo mawonekedwe ake ndi ofunika kwambiri pakuwongolera luso lonse la makina amtundu wa hydraulic, makamaka pakuyendetsa pamagetsi, kuwongolera kwakutali opanda zingwe ndi ma waya akutali.

Pamene chipangizo chomwe chilipo chofanana cha electro-hydraulic valve manual pressure relief chikugwiritsidwa ntchito, chipangizo chothandizira kupanikizika nthawi zambiri chimayenda ndi spool nthawi zonse, ndipo pamakhala kusagwirizana kwa chisindikizo, zomwe zimakhudza kulondola kwa spool. Nthawi yomweyo, chipangizo chomwe chilipo chofananira cha electro-hydraulic valve manual pressure relief chida ndizovuta kugwiritsa ntchito.
