Excavator E330D E336D Hydraulic Direction Solenoid Valve Coil

Coil mfundo

1.Inductance ndi chiŵerengero cha kusinthasintha kwa maginito omwe amapangidwa mkati ndi kuzungulira kondakitala pamene kusinthasintha kwamakono kumadutsa pa kondakitala, ndi maginito a maginito a conductor mpaka pano omwe amapanga maginitowa.

2.Pamene DC yamakono ikudutsa mu inductor, mzere wokhazikika wa magnetic field ukuwonekera mozungulira, umene susintha ndi nthawi; Komabe, mphamvu ya maginito ikadutsa pa koyiloyo, mizere ya maginito yozungulira imasintha pakapita nthawi. Malinga ndi lamulo la Faraday la electromagnetic induction-magnetic induction, kusintha kwa maginito kumapanga mphamvu yochititsa chidwi pamapeto onse a koyilo, yomwe ili yofanana ndi "magetsi atsopano". Pamene kuzungulira kotsekedwa kupangidwa, kuthekera kotereku kumapanga mphamvu yochititsa chidwi. Malinga ndi lamulo la Lenz, kuchuluka kwa mizere ya maginito yomwe imapangidwa ndi maginito apano akuyenera kuyesa kuletsa kusintha kwa mizere yoyambirira ya maginito. Chifukwa kusintha koyambirira kwa mizere ya maginito kumachokera ku kusintha kwa magetsi osinthika akunja, kuchokera ku cholinga, coil inductance ili ndi mawonekedwe oletsa kusintha kwaposachedwa kwa dera la AC. Koyilo ya inductive ili ndi mawonekedwe ofanana ndi inertia mu zimango, ndipo imatchedwa "kudzilowetsa" mumagetsi. Nthawi zambiri, zipsera zimachitika panthawi yomwe chosinthira mpeni chimayatsidwa kapena kuzimitsidwa, zomwe zimachitika chifukwa cha kuthekera kwakukulu komwe kumachitika chifukwa chodzipangira nokha.

3.Mwa mawu amodzi, pamene coil inductance ikugwirizana ndi magetsi a AC, mizere ya maginito mkati mwa coil idzasintha nthawi zonse ndi njira yosinthira, zomwe zimapangitsa kuti phokoso likhale lopitirirabe. Izi electromotive mphamvu kwaiye ndi kusintha panopa wa koyilo palokha amatchedwa "self-induced electromotive mphamvu".

4.Zitha kuwoneka kuti inductance ndi parameter yokha yokhudzana ndi chiwerengero cha kutembenuka, kukula, mawonekedwe ndi sing'anga ya koyilo. Ndilo muyeso wa inertia wa coil inductance ndipo alibe chochita ndi ntchito panopa.
