Treatment method for 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, the heating of the solenoid valve coil will not affect the normal operation of the solenoid valve as long as it is within the reasonable temperature scale of the product. However, if the operating temperature is too high, it will affect the operating efficiency of the solenoid valve and even damage the parts of the solenoid valve. The causes and treatment methods of heating of solenoid valve coil are as follows:

1. First check whether the temperature of the solenoid valve coil is within the temperature scale used by the product. This can be found in the specification of the solenoid valve product. Generally, there is a detailed explanation of the operation of the solenoid valve and the ambient temperature in the specification. If no manufacturer can be consulted according to the type.

Generally, the electromagnetic valve with a slight fever is attributed to the normal phenomenon of product operation, as long as it does not exceed a certain temperature, it is okay, which the user can center.

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 during practical work, it is very simple to form the overheating phenomenon of the solenoid valve coil. And if this is the reason, only new solenoid valve products can be replaced, so it is very important to choose the type of users.

3. If the solenoid valve coil is equipped with an energy-saving maintenance module (the function of the energy-saving module is to save energy and cool the solenoid valve coil), and this energy-saving maintenance module presents problems, it will also cause the coil to heat up.

4, overload operation

That is, the working environment of solenoid valve practice exceeds the working environment scale of solenoid valve product design. For example, the ambient temperature and medium temperature are too high, perhaps the pressure is too high and the power supply voltage is too high.

5. The quality problem of solenoid coil itself.

This reason is less likely, because manufacturers will not affect their brand promises with low-quality products. Therefore, attention will be paid to the quality of solenoid valve products.

If the heating temperature of solenoid valve coil is within the operation scale of the product, users can use it without mind, which will not affect the operation of solenoid valve.
