hydraulic mpope proportional solenoid vavu 195-9700

Proportional valve ndi mtundu watsopano wa chipangizo chowongolera ma hydraulic. Mu valavu yamagetsi wamba, valavu yothamanga ndi valavu yolowera, ma electromagnet wofananira amagwiritsidwa ntchito m'malo mwa gawo loyang'anira, ndipo kukakamiza, kuyenda kapena mayendedwe akuyenda kwamafuta kumayendetsedwa patali molingana ndi chizindikiro chamagetsi cholowera mosalekeza komanso molingana. Ma valve ofananira nthawi zambiri amakhala ndi chiwongola dzanja, ndipo kuthamanga kwa zotulutsa ndi kuthamanga kwake sikungakhudzidwe ndi kusintha kwa katundu.

Ndi chitukuko cha ma hydraulic transmission and hydraulic servo systems, machitidwe ena a hydraulic omwe amafunikira kulamulira kosalekeza kwa kupanikizika, kutuluka ndi kuwongolera popanda kuwongolera kwakukulu kwawonekera pakupanga. Popeza zigawo za hydraulic wamba sizingakhale zodzaza kuti zikhale ndi zofunikira zina za servo, komanso kugwiritsa ntchito ma electro-hydraulic servo mavavu ndi owononga kwambiri chifukwa zofunikira zowongolera sizili zapamwamba, valavu yowongolera molingana pakati pa zigawo wamba za hydraulic (kusintha kosintha) ndi valavu ya servo (kuwongolera mosalekeza) yapangidwa m'zaka zaposachedwa.

Electro-hydraulic proportional control valve (yotchedwa proportional valve) ndi mtundu wa valve yotsika mtengo ya electro-hydraulic control valve yokhala ndi ntchito yabwino yolimbana ndi kuipitsidwa. Kukula kwa valavu yofananira kumakumana ndi njira ziwiri, imodzi ndikusintha njira yosinthira pamanja ya valavu yamtundu wa hydraulic yokhala ndi ma electromagnet yofananira, pamaziko a valavu yamtundu wa hydraulic: kukulitsa njira zosiyanasiyana zofananira, kuthamanga ndi ma valve otaya; Chachiwiri ndi chakuti ena oyambirira opanga ma electro-hydraulic servo valve amapangidwa atachepetsa mapangidwe ndi kupanga zolondola pamaziko a ma electro-hydraulic servo valves.

Proportional valavu wapangidwa ndi DC proportional solenoid ndi hydraulic valavu mbali ziwiri, proportional valavu kukwaniritsa kulamulira mosalekeza pachimake ndi ntchito proportional solenoid, proportional solenoid zosiyanasiyana, koma mfundo ntchito ndi chimodzimodzi, iwo amapangidwa molingana proportional. Zofunikira zowongolera ma valve.
