The guiding structure of the four-column hydraulic press adopts the round guide sleeve to guide on four posts. When the force is eccentric, it depends on the precision of the guide sleeve to closely cooperate with the guide.
First of all, common-sense operation errors of hydraulic press. For example, the reversed connection of three-phase power supply, insufficient oil level in the fuel tank, or not-properly adjusted pressure regulating valve to increase the pressure. This is usually the reason that occurs when a novice first uses a hydraulic press.
Add the hydraulic oil of the four-column hydraulic press to the specified liquid level. Connect the external power supply according to the requirements of the circuit diagram, start the four-column hydraulic oil pump, and adjust the rotation direction.
