Liebherr excavator magawo a electromagnetic valve coil

Mfundo yogwiritsira ntchito ya solenoid valve coil

1.Inductance imatanthawuza kusinthasintha kwa maginito mkati ndi mozungulira woyendetsa pamene woyendetsa akudutsa mumsewu wamakono, ndi chiŵerengero cha maginito a maginito a conductor mpaka pano ndi maginito.

2.Pamene inductor ikudutsa pakalipano ya DC, malinga ngati mizere ya maginito yozungulira ikukhazikika, sidzasintha ndi nthawi; Koma pamene koyilo ya electromagnetic idutsa njira yolankhulirana, mizere ya maginito imasintha ndikupita kwa nthawi. Malinga ndi kusanthula kwa magetsi a Faradi a electromagnetic induction law-magnetic magetsi, mizere yamagetsi yomwe yasinthidwa imapangitsa kuti mbali zonse ziwiri za koyiloyo zitheke, zomwe ndizofanana ndi "magetsi atsopano". Pamene chigawo chotsekedwa chikachitika, mphamvu yochititsa chidwi idzayambitsa zamakono. Malinga ndi lamulo la Leng Ci, kusintha kwa mizere yoyambirira ya maginito kuyenera kupewedwa momwe mungathere. Chifukwa kusintha kwa mizere yapachiyambi ya maginito kumachokera ku kusintha kwa magetsi osinthika akunja, kuchokera ku zotsatira za cholinga, coil inductance ili ndi khalidwe lopewa kusintha kwamakono mu dera loyankhulana. Koyilo yolowera ili ndi mawonekedwe ofanana ndi inertia yamakina, ndipo imatchedwa "kudzilowetsa" mumagetsi. Nthawi zambiri, switch ya mpeni ikayatsidwa kapena kuzimitsa, moto umachitika, zomwe zimachitika chifukwa champhamvu yamphamvu yodzidzimutsa.

3.Mwa mawu amodzi, pamene solenoid valve coil imalandira magetsi oyankhulana, mizere ya maginito mu coil idzasintha ndi kusintha kwamakono, zomwe zimapangitsa kuti pakhale kulowetsedwa kwa electromagnetic mu koyilo. Kuthekera kumeneku komwe kumachitika chifukwa cha kusintha kwa koyilo komweko kumatchedwa "self-induced electromotive force".

4.Zitha kuwoneka kuti inductance imangogwirizana ndi chiwerengero, kukula, mawonekedwe ndi sing'anga ya coil, yomwe ndi inertia ya inductance coil ndipo ilibe kanthu kochita ndi kunja.
