EX09301 4V mndandanda wokwera mbale-wokwera-proof solenoid valve koyilo

Mfundo ya ntchito

Ndipotu, mfundo yogwira ntchito ya mankhwala a coil si yovuta. Choyamba, tiyenera kudziwa kuti mu valavu solenoid pali chotsekereza patsekeke, ndipo mabowo amapangidwa mbali zosiyanasiyana, ndipo dzenje lililonse adzatsogolera chitoliro mafuta osagwiritsidwa ntchito. Pakatikati mwa dzenje pali valavu, ndipo pali ma electromagnets awiri kumbali zonse ziwiri, ndipo coil ya electromagnetic kumbali imeneyo imakhala ndi mphamvu, kotero thupi la valve lidzakopeka ndi mbali iti, ndipo kayendetsedwe ka valavu kakhoza kuyendetsedwa. , kotero kuti dzenje lotulutsa mafuta likhoza kutayikira kapena kutsekedwa, ndipo dzenjelo nthawi zambiri limatseguka kwa nthawi yayitali. Mafuta a hydraulic amalowa m'mapaipi osiyanasiyana otulutsa mafuta kudzera mukuyenda kwa valavu, ndiyeno pisitoni ya silinda yamafuta imadutsa kupsinjika kwamafuta, ndipo pisitoni imakankhira ndodo ya pisitoni kuwongolera maginito amagetsi, ndiyeno lamulirani zida zogwirira ntchito.

Chigawo chofanana

1. Malinga ndi njira yokhotakhota ya koyilo, imatha kugawidwa m'mitundu iwiri: koyilo yamtundu wa T ndi mtundu wa I.

Pakati pawo, koyilo yamtundu wa "I" imatanthawuza kuti koyiloyo imayenera kuzunguliridwa mozungulira pachimake chachitsulo chokhazikika ndi zida zosuntha, kuti positiyi ichitike pomwe pano ikudutsa pa koyilo, ndipo zida zosunthika zitha kukopa choyimiriracho. chitsulo pakati.

Koyilo yooneka ngati T imadulidwa pachimake chachitsulo chokhala ndi mawonekedwe a "E" ndi wosanjikiza, kotero kuti koyiloyo ikasangalala, imatulutsa mphamvu yowoneka bwino, ndipo mphamvu yowoneka bwino imatha kukoka zidazo kupita pachimake chachitsulo chokhazikika. .

2. Malinga ndi mawonekedwe apano a koyiloyo, koyilo yamagetsi yotsimikizira kuphulika imatha kugawidwa kukhala koyilo ya AC ndi koyilo ya DC.

Mu koyilo ya AC, kusintha kwa maginito permeability nthawi zambiri sikungasiyanitsidwe ndi kusintha kwa zida. Pamene kusiyana kwa mpweya kuli kwakukulu, mphamvu ya maginito ndi mphamvu yowonongeka idzakhala paliponse, kotero pamene mphamvu yaikulu imalowa mu coil kuti iwononge, kuyambika kwapamwamba kumapangitsa kuti koyilo ya AC iyankhe mwamphamvu.

Mu coil ya DC, chomwe chiyenera kuganiziridwa ndi gawo lomwe limadyedwa ndi chotsutsa.
