Solenoid control valve coil K23D-2 pneumatic element

Kusiyana pakati pa koyilo ya AC ndi koyilo ya DC

Pali mitundu iwiri ya ma electromagnetic relay: AC ndi DC. M'malo mwake, magetsi a DC akagwiritsidwa ntchito kumapeto onse a koyilo, zomwe zimapangidwira zimatsimikiziridwa ndi kukana kwa koyilo. Chifukwa resistivity yamkuwa ndi yaing'ono kwambiri, pofuna kuonetsetsa kuti panopa si lalikulu kwambiri, koyilo ayenera kupangidwa ndi woonda waya awiri ndi matembenuzidwe angapo. Komano, koyilo ya AC imatsimikiziridwa ndi momwe amachitira, chifukwa chake koyiloyo iyenera kupangidwa ndi waya wandiweyani wa waya ndi matembenuzidwe ochepa. Choncho, pamene 24V AC relay ikugwiritsidwa ntchito mu dongosolo la DC 24V, relay idzawotcha mwamsanga chifukwa kukana sikokwanira. Komabe, pamene DC relay ikugwiritsidwa ntchito mu AC system, n'zosapeŵeka kuti relayyo siimakoka mwamphamvu kapena sangathe kukoka chifukwa chakuchita kwake kwakukulu.

1.Kawirikawiri, pali mitundu iwiri yolumikizirana: AC ndi DC, ndipo AC omwe ali ambiri 24VAC, 220VAC ndi 380VAC. Ma AC relay coil coil amayenera kukhala ndi chipilala chotchinga, chomwe ndi chosavuta kuweruza, koma ma AC ang'onoang'ono otumizirana ma AC alibe chipilirochi. Pali magawo ambiri amagetsi a DC, monga 6, 12 ndi 24 volts. Koyilo ya relay nthawi zambiri imakhala yopyapyala ndipo pachimake chake mulibe mzati wophimba.

2.AC contactors akhoza m'malo DC contactors ngati mwadzidzidzi, ndipo kukoka-mu nthawi sangakhoze kupitirira 2 hours (chifukwa kutaya kutentha kwa AC coils ndi oipa kuposa DC, amene anatsimikiza ndi mapangidwe awo osiyana). Mosiyana ndi zimenezi, DC sangathe m'malo AC contactors.

3.The kutembenukira koyilo wa AC contactor ndi ochepa, pamene awo a DC contactor ndi ambiri, amene akhoza kusiyanitsidwa voliyumu koyilo.
