DX60 12V 24V solenoid valve coil hole 16 height 42 excavator accessories

    The movable core in the solenoid valve coil is attracted by the coil when the valve is energized, driving the valve core to move, thus changing the on-state of the valve; The so-called dry or wet type only refers to the working environment of the coil, and there is no big difference in the valve action; However, the inductance of a hollow coil and the inductance after the addition of an iron core in the coil is different, the former is small, the latter is large, when the coil through alternating current, the impedance generated by the coil is not the same, for the same coil, plus the same frequency of alternating current, the inductance will vary with the core position, that is, its impedance varies with the core position, the impedance is small. The current flowing through the coil will increase.

     The structure of solenoid valve is composed of electromagnetic coil and magnetism, and it is a valve body with one or more holes. When the coil is energized or de-energized, the operation of the magnetic core will cause the fluid to pass through the valve body or be cut off, so as to change the direction of the fluid. The burning of solenoid valve coil will cause solenoid valve failure, and the failure of solenoid valve will directly affect the action of switching valve and regulating valve. What are the reasons for the burning of the solenoid valve coil? One of the reasons is that when the coil is wet, magnetic leakage occurs due to its poor insulation, resulting in excessive current in the coil and burning. Therefore, attention should be paid to preventing rain from entering the solenoid valve. In addition, the spring is too hard, resulting in excessive reaction force, too few coil turns and insufficient suction, which will also cause the solenoid valve coil to burn.
