40-1836 / 3000249 / 3003138 HYDAC Type Hydraulic Solenoid Coil
This 3000249 / 3003138 Hydraulic Solenoid Coil is an important accessory for WSM06020 Hydac Electro Valve. According to the working principle of the electromagnet, when the solenoid reversing valve spool is stuck, the armature cannot be moved into position after the electromagnet is energized. At this time, the coil temperature will rise sharply and it will easily lead to burning in a short time. Most of the valve coil failures. Therefore, in the actual maintenance, if the coil burns out, first check whether the work of the solenoid valve is smooth. After removing the fault such as the valve plug, replace the new coil, otherwise the coil may still be burnt after replacement. The inner diameter and length of the coil replaced by the electromagnetic reversing valve must be the same as the original product, otherwise it cannot be used.

The reasons for hydraulic solenoid coil burning are generally:
1 Solenoid coil quality problem (Because of the high price of copper, the coil uses copper alloy with low copper content, even aluminum, the resistance becomes larger.)
2. Turn off overvoltage breakdown;
3 The power supply voltage is too high;
4 repeated shocks, frequent switching to generate overcurrent or overheating;
5 The installation is unstable, and the mechanical vibration is too large, causing the coil to wear out and short-circuit. The possibility of over-voltage breakdown is very large. The electromotive force is equal to the multiplication of the current multiplied by the current rate (for time). Usually the reverse-connected diode can be very It is easy to solve such problems (the diode withstand voltage is 1.5-2 times higher than the coil voltage, and the current is 1.5-2 times larger than the coil current).
6. The waterproofness of the electromagnet.
The thermal energy generated by the thermal effect of the current = the square of the current multiplied by the resistance (coil) multiplied by time. That is: Q = I² x R x t.
If a coil is made using a thicker wire, the resistance R of the coil is small. Under the same current conditions, the thermal energy generated by the thermal effect of the current is small without causing the coil to burn out. Of course, the current through the coil can also be reduced. The thermal energy generated by the thermal effect of the current is reduced, but the generated magnetic force is also reduced, and the electromagnet may not work properly.
