Can the solenoid valve continue to work for too long? What will be the impact?

1.In the field of industrial control, solenoid valve is a common state actuator. Under its operation, the current needs to be kept at all times, the loss is large, and the coil is prone to heat. It can be seen that in the field of industrial control, the burning of the solenoid valve coil is ubiquitous. The energization time of the solenoid valve mainly refers to the energization time of its coil, which is also the core driving component of the solenoid valve. Its quality has a great influence on the performance and service life of the solenoid valve.

2.We all know that solenoid valves are generally divided into AC220 and DC24V, and AC110, AC24, and DC12 are not commonly used. And its structure is basically the same. It consists of electromagnetic components and valve body. The electromagnetic part of the solenoid valve is composed of a fixed iron core, a movable iron core and a coil, and the valve body is composed of a sliding iron core, a sliding valve sleeve and a spring seat. Therefore, when the solenoid valve coil is energized or de-energized, the movement of the spool will make the fluid pass or be cut off, so as to achieve the purpose of switching and changing the direction of the fluid.

3.As for the long-term energized work of the solenoid valve, can the solenoid valve withstand it? Solenoid valves generally will not burn out the coils. Now the solenoid valve coils are basically ED. The ED here refers to the energization rate, and the solenoid valve can meet the long-term use. Indicates that it can be continuously powered on. However, if the use method does not meet the ED, the temperature of the coil will rise to exceed the limit temperature of the insulation type, and in severe cases, the coil will still be burned.

4.That is to say, if the power-on time is too long, it depends on the specific situation on site. Although the power-on time is long and the heat is seriously hot, it generally does not affect its work. However, if the solenoid valve coil is energized, under no-load conditions, the coil will definitely burn out if it is energized for a long time. The influence of long-term electrification of the solenoid valve is generally that the heat is serious, so do not touch it with your hands. If the solenoid valve coil burns out, it will cause the valve or other actuators to fail to work normally, seriously affecting the normal production of the workshop.

To sum up, the solenoid valve is very important in the production process, and the correct choice is very important. Here are a few reasons for your selection:

1. Select the material of the solenoid valve according to the fluid parameters;

2. Select the type of solenoid valve according to the length of continuous working time;

3. Select the type of solenoid valve according to the actuator or application;

4. Choose according to the type of valve;

5. Select according to environmental conditions;

6. Select according to the division of dangerous areas;

7. Select according to voltage.
