Check method for oil leakage on the surface of four-column Hydraulic Press:
- 1. The physical isolation method increases the distance between the disturbed circuit or device of the four-column hydraulic press and the source of interference. Since the interference intensity is inversely proportional to the square of the distance, it is recommended that you use a stable power supply. In order to suppress the power supply noise of the four-pillar hydraulic press and the interference between the power supply and the grounding cable, the power supply and the numerical control device can be connected and isolated.
- 2. Grounding method: A four-column hydraulic press connects its shell to the ground. For protective grounding, if the system grounding of the four-pillar hydraulic press is connected to the earth as the system grounding, anti-interference can also be achieved through protective grounding or system grounding. To
- 3. Shielding method. In order to prevent the four-column hydraulic press and its components from being affected by the external electromagnetic field, isolation and shielding measures are usually adopted, and electromagnetic shielding or discharge is carried out through reflection or absorption. To
- 4. The filter can suspend input interference and interference induced on the signal transmission line. Commonly used are low-pass filters and DC filters, which are generally installed between the power supply of the four-column hydraulic press and the numerical control device.
