Causes and treatment of heating of solenoid valve coil

When the solenoid valve product is working, it will be found that the solenoid valve coil is hot, which is generally caused by the long working time of the solenoid valve. However, as long as it is within the reasonable temperature range of the product, the heating of the solenoid valve coil will not affect the normal operation of the solenoid valve. However, if the working temperature is too high, it will affect the working efficiency of the solenoid valve and even damage the parts of the solenoid valve. The causes and treatment methods of solenoid valve coil heating are as follows:

1. First, check whether the temperature of the solenoid valve coil is within the temperature range that the product is suitable for. This can refer to the manual of the solenoid valve product, and generally there are specific instructions on the work of the solenoid valve and the ambient temperature in the manual. If not, you can consult the manufacturer according to the model. Generally, the electromagnetic valve with a little fever belongs to the normal phenomenon of product work, as long as it does not exceed a certain temperature, the user can rest assured. 2, due to improper user selection.

There are two kinds of solenoid valve products: normally open and normally closed. If the user uses a normally closed solenoid valve, but it is normally open in actual work, it is easy to cause the coil of the solenoid valve to overheat. And if this is the reason, only new solenoid valve products can be replaced, so it is very important for users to choose the model. 3. If the solenoid valve coil is equipped with an energy-saving protection module (the function of the energy-saving module is to save energy and cool the solenoid valve coil), and this energy-saving protection module fails, it will also cause the coil to heat up.

4. Overload work is the actual working environment of the solenoid valve, which exceeds the working environment range of the solenoid valve product design. For example, the ambient temperature and medium temperature are too high, or the pressure is too high and the power supply voltage is too high. 5. The quality problem of solenoid valve coil itself is less likely to happen, because manufacturers will not affect their brand reputation with low-quality products. Therefore, attention will be paid to the quality of solenoid valve products. If the heating temperature of the solenoid valve coil is within the working range of the product, users can use it without paying attention, which will not affect the work of the solenoid valve.
