Made in China New Common Rail Injector Solenoid Valve F00RJ02702 Diesel Fuel Injector Parts

With the continuous improvement of modern industrial automation and intelligence level, solenoid valve as a key component in the field of fluid control, in the industrial control system plays an increasingly important role. Solenoid valve coil as its driving parts, its performance stability and reliability is directly related to the overall performance of the solenoid valve. However, in practice, the solenoid valve coil heating problem has become an important factor affecting its performance and life of the solenoid valve coil heating problem will not only lead to the coil itself insulation performance decline, accelerate the aging of the coil, and even lead to short-circuit, burned and other faults, but also may have a thermal impact on the surrounding equipment, triggering the chain of failures, thus affecting the stability of the entire industrial system and safety. Therefore, in-depth study of the causes of solenoid valve coil heating problems, factors and solutions to improve the reliability of the solenoid valve, extend the service life and promote the stable operation of industrial automation system is of great significance.

The reason for the solenoid valve coil getting hot could be these reasons. When the coil of the solenoid valve is energised, the iron core will be suctioned, and a closed magnetic circuit will be formed. And inductance presents the largest state under the design process, the heat presents the normal state, but the core in the energised state can not be smoothly suction, which will lead to the coil inductance presents the state, the impedance will also be reduced, and the current will increase accordingly, resulting in excessive coil current and other problems, which seriously affects the service life of the solenoid valve. In the oil, impurities and deformation and other issues under the influence of the core activity is impeded, which will lead to the power when the overall action is too slow, can not be normal suction, which will lead to the coil power will be presented when the impedance is low, then it will induce coil heating.
