Why does the electromagnet heat up in the calendar printing in summer? Source: www.jdzszp.cn
1. The temperature is high; the heat dissipation effect is mainly caused by the temperature difference between the electromagnet and the surrounding environment; the smaller the temperature difference, the less ideal the heat dissipation effect;
2. The voltage is too low; the power supply used by the offset printing machine is best stabilized at 220v/50HZ, especially to guard against the interference of the surrounding electrical appliances; in summer, due to the extensive use of electrical equipment, the voltage is too low, which aggravates the electromagnet. load, causing fever;
3. The resistance of the electromagnet tension spring is too large; the resistance of the tension spring is too large, causing heat generation; for the above situation, we recommend using a continuous (non-ordinary household graded boost) AC regulated power supply to improve the operation quality, Extend the service life of the machine; on the other hand, we are also stepping up the research and development of electromagnets with stronger magnetic force to effectively solve the problem of insufficient magnetic force, and this result will be brought to the market soon.
