1. The physical isolation method increases the distance between the disturbance circuit or device of the four-column hydraulic press and the interference source. Since the interference intensity is inversely proportional to the square of the distance, it is recommended to use a stable power source. In order to restrain the noise of the power supply of the four-column hydraulic press and the interference between the power supply and the grounding cable, the power supply and the CNC device can be connected and isolated
2. Shielding method. In order to prevent the four-column hydraulic press and components from being affected by external electromagnetic fields, isolation shielding measures are usually adopted, which are electromagnetic shielding or discharge through reflection or absorption.
3. Grounding mode: four-column oil press will connect its shell with the earth. For protection grounding, if the system grounding of the four-column hydraulic press is connected to the earth as the system grounding, anti-interference can also be realized through the form of protection grounding or system grounding.
4. The filter can suspend input interference and induced interference on the signal transmission line. Commonly used are low-pass filter and DC filter, which are generally installed between the power supply and the numerical control device of the four-column hydraulic press.
