DX60 12V 24V solenoid vavu koyilo dzenje 16 kutalika 42 excavator Chalk

Chingwe chosunthika mu valavu ya solenoid chimakopeka ndi koyilo pamene valavu ili ndi mphamvu, kuyendetsa phokoso la valve kuti lisunthe, motero kusintha pa-state ya valve; Chomwe chimatchedwa chowuma kapena chonyowa chimangotanthauza malo ogwirira ntchito a koyilo, ndipo palibe kusiyana kwakukulu mu ntchito ya valve; Komabe, inductance ya koyilo yopanda kanthu ndi inductance pambuyo powonjezera chitsulo pakati pa koyilo ndi yosiyana, yoyamba ndi yaying'ono, yotsirizirayi ndi yayikulu, pamene koyiloyo imadutsa pakali pano, kutsekeka komwe kumapangidwa ndi koyilo sikuli kokwanira. chimodzimodzi, kwa koyilo yemweyo, kuphatikiza pafupipafupi kusinthasintha kwapano, inductance idzasiyana ndi malo oyambira, ndiko kuti, kutsekeka kwake kumasiyana ndi malo oyambira, kutsekereza kumakhala kochepa. Zomwe zikuyenda kudzera mu koyilo zidzawonjezeka.

Mapangidwe a valavu ya solenoid amapangidwa ndi coil yamagetsi ndi maginito, ndipo ndi thupi la valve lomwe lili ndi bowo limodzi kapena angapo. Pamene koyiloyo ipatsidwa mphamvu kapena kuchotsedwa mphamvu, kugwira ntchito kwa maginito kumapangitsa kuti madziwo adutse mu thupi la valve kapena kudulidwa, kuti asinthe njira yamadzimadzi. Kuwotcha kwa valavu ya solenoid kumayambitsa kulephera kwa valve ya solenoid, ndipo kulephera kwa valavu ya solenoid kudzakhudza mwachindunji kusintha kwa valve ndi valavu yoyendetsa. Kodi ndi zifukwa ziti zomwe zimawotchera valavu ya solenoid? Chimodzi mwazifukwa zake ndikuti koyiloyo ikanyowa, kutayikira kwa maginito kumachitika chifukwa cha kusakhazikika kwake, zomwe zimapangitsa kuti koyiloyo ikhale yochulukirapo komanso kuyaka. Choncho, chidwi chiyenera kuperekedwa kuti mvula isalowe mu valve ya solenoid. Kuphatikiza apo, kasupe ndi wovuta kwambiri, zomwe zimapangitsa kuti pakhale mphamvu yochulukirapo, kutembenuka kwa ma coil ochepa komanso kusayamwa kokwanira, zomwe zingapangitse kuti koyilo ya solenoid iyatse.
