Solenoid coil

Solenoid coil when the electricity activities within the core for the coil attracted to move, drives the valve core is moving, so as to change the valve on state; The so-called dry or wet only refers to the working environment of coil, for valve action, no big difference.

But, as we know, a hollow coil inductance and to join the core within the coil inductance is different, after the former, the latter is large, when the coil tong to alternating current (ac), produced by the coil impedance is different also, for the same coil, coupled with the same frequency alternating current, the inductance will vary depending on the core position, namely the impedance varies with the core position, impedance hours, flows through the coil current will increase. > the solenoid coil is often too warm When the solenoid valve coil is in working condition (electricity), core sucked, form a closed magnetic circuit. The inductance in the largest state consists of timing. The fever is normal, but the core is not smooth and electricity, reduced the volume of coil inductance, resistance is reduced, current increases accordingly, thus cause the coil current is too big, life is affected, so the oil make core activity is blocked, energized the action is slow, can't even normal is completely off, make coil electricity often is in a state of impedance fewer than normal, perhaps factors of wire coil.
