Ma hydraulic solenoid valve 4212228 TOSD-06-151 zida zamakina omanga

Electro-hydraulic proportional valve imatchedwa proportional valve. Mavavu wamba a hydraulic amatha kuwongolera kuthamanga ndi kuyenda kwamadzimadzi pokhazikitsa kale. Komabe, pamene makina opangira zida amafunikira kusintha kapena kuwongolera kosalekeza kwa kukakamiza ndikuyenda kwa ma hydraulic system panthawi yogwira ntchito, mwachitsanzo. Gome la ntchito likufunika kuti mukwaniritse chakudyacho pa liwiro la pang'onopang'ono, mofulumira komanso pang'onopang'ono kusintha kosalekeza panthawi ya chakudya cha ntchito, kapena kutsanzira njira yoyendetsera bwino kwambiri kuti mukwaniritse mphamvu ya mphamvu. Mavavu wamba hayidiroliki sangathe kukwaniritsa. Panthawiyi, ma hydraulic system amatha kuyendetsedwa ndi electro-hydraulic proportional valve.

Electro-hydraulic proportional valve ndi mtundu wa valavu yomwe imayendetsa mosalekeza komanso molingana ndi kayendetsedwe ka kayendetsedwe kake, kuthamanga ndi kuthamanga kwa hydraulic system molingana ndi chizindikiro chamagetsi. Zili ndi magawo awiri: chipangizo chosinthira magetsi ndi makina ofananira ndi ma hydraulic control valve body. Yoyamba imasintha ma siginecha amagetsi olowera kukhala mphamvu yamakina ndi kutulutsa kosuntha mosalekeza komanso molingana, pomwe yomalizayo imatulutsa mphamvu ndikuyenda mosalekeza komanso molingana ndi kuvomereza mphamvu zamakina ndi kusamuka.
Kupanga valavu ya electro-hydraulic proportional valve makamaka kuli ndi njira ziwiri: imodzi ndikusinthira chida chosinthira chamagetsi amtundu wa hydraulic ndi ma electromagnetic ofananira kapena kusintha ma elekitiroma wamba. Yachiwiri imapangidwa ndi electro-hydraulic servo valve kuti ikhale yosavuta kupanga ndikuchepetsa kulondola. Mavavu ofananira omwe akufotokozedwa pansipa onse amatanthawuza zakale, zomwe ndizofala kwambiri masiku ano. Imasinthasintha ndi ma valve wamba a hydraulic.
