Electromagnetic coil for automatic control tanker 0545EX

As one of the key parts of the solenoid valve, once the explosion-proof solenoid valve coil has problems, it will seriously affect the routine application of the solenoid valve, but how to judge the quality of the solenoid valve coil? You can't tell it by human eyes, so you must use professional equipment to test it. How to measure it? Let's take a look at it together.

1. If the solenoid valve coil manufacturer wants to measure whether the solenoid valve coil is damaged, we can use a multimeter to measure it, and then we can distinguish it according to static data detection. The actual operation steps are as follows: connect the pen tip of the multimeter with the solenoid valve coil needle, and observe the value on the multimeter. If the value is higher than the rated value, it indicates that it has been damaged.

If the indicated value is lower than the rated value, it indicates that the locked rotor of the solenoid valve coil has a short circuit fault.

If the indicated value is infinite, it indicates that the electromagnetic coil of HBD water valve has led the way.

All the above conditions indicate that the solenoid valve coil has been damaged, and it is suggested to replace it with a new one immediately.

2. Another way to test the quality of the solenoid valve coil is to apply a 24-volt switching power supply and connect it to the solenoid valve coil. If it can be connected until it sounds, it means it is good. If there is no sound, it means it is broken.

3. In addition, a way to measure whether the solenoid valve coil is normal is to put a small screwdriver around the metal bar in the solenoid valve coil, and then plug in the rechargeable battery valve. If the small screwdriver is magnetized, it indicates that the solenoid valve coil is good, on the contrary, it indicates that the solenoid valve coil has been damaged.

There are many ways to measure the advantages and disadvantages of solenoid valve coils. At this stage, the solenoid valve is a long and electric power switch. Once its solenoid coil is damaged, it is very easy to cause safety accidents. Therefore, we cannot be careless about this matter and find that the solenoid valve coil is damaged. We propose to dismantle and replace it immediately.
