TM70302 valavu yofananira ya solenoid Excavator solenoid valve

Chitsanzo chogwiritsira ntchito cha electro-hydraulic proportional valve mumakina omanga
Chithunzi cha hydraulic system chamtundu wina wa crane yamagalimoto, momwe gawo lokhalo la electro-hydraulic proportional valve limakoka. Makinawa amatenga ma valve atatu a TECNORDTDV-4/3 LM-LS/PC molingana ndi njira zingapo, mzere wamafuta ozindikira katundu m'mavavu atatu opindika udzasankhidwa pakukakamiza kwakukulu kwa katundu atatu omwe akugwira ntchito ku doko loyang'anira kutali la chithandizo. valavu, sinthani mphamvu ya valve yothandizira, kuti mphamvu yotulutsa pampu ya hydraulic ingokwaniritsa zosowa za dongosolo, kuti mukwaniritse cholinga china chopulumutsa mphamvu. Kuthamanga kwa mafuta oyendetsa galimoto kumapangitsa kuti valavu iliyonse ikhale yokhudzana ndi kutsegula kwa valve, ndipo ilibe kanthu ndi katunduyo, ndipo katundu wonyamula ndi mbale ya valve alibe chochita ndi izo, kotero kuti liwiro la katundu likhoza. kulamulidwa mwakufuna pansi pa katundu uliwonse.
Chitsanzo cha kuwongolera kwapamanja ndi electro-hydraulic proportional pilot of bulldozer fosholo. Pamene valavu yamtundu wa katatu ya solenoid ilibe mphamvu, kupanikizika kwa woyendetsa ndege kumagwirizanitsidwa ndi valavu yoyendetsa ndege yowonongeka, ndipo valavu ya shuttle imasankha kupanikizika kuchokera ku valavu yoyendetsa galimoto kuti athetse kusintha kwa hydraulic direction valve; Pamene valavu ya solenoid yamitundu iwiri imakhala ndi mphamvu, mafuta oyendetsa oyendetsa ndege amatsogolera ku njira zitatu zowonongeka zowonongeka, ndipo shuttle valve imayendetsa valavu yosinthira hydraulic direction.

Mfundo yogwirira ntchito, kapangidwe kake ndi mawonekedwe a ma electro-hydraulic proportional valve akudziwitsidwa mwachidule, ndipo mfundo yozindikira katundu ndi kukakamizidwa kwa valve yofananira imawunikidwa ndikuwerengedwa. Kugwiritsiridwa ntchito kosiyanasiyana kwa ma electro-hydraulic proportional valve, makamaka pakuwongolera oyendetsa ndi kuwongolera kwakutali kwamakina omanga, akukambidwa. Electro-hydraulic proportional valve ndi yofunika kwambiri kuti ikhale yosavuta kugwiritsa ntchito makina omanga, kuwongolera magwiridwe antchito komanso kulondola, ndikuzindikira magwiridwe antchito anzeru.
Ndipo kuchuluka kwa ntchito kumapangitsa kuti luso lazopanga zamakina likhale lokulirapo,
