What is the reason for insufficient or no oil supply in the hydraulic press?

What is the reason for insufficient or no oil supply in the hydraulic press? When the air entering the oil reaches a certain amount, it will cause insufficient oil supply to the system or even no oil supply. Furthermore, if the hydraulic oil cannot flow into the suction port in time, cavitation will occur in the pump suction port, causing premature damage to the plunger seal and cavitation of the plunger cylinder wall.

Hydraulic press pressure is insufficient and the cylinder is not running smoothly. Repair methods

1. Elimination method: Replace the piston or sealing ring and maintain a reasonable clearance. 2. Cause of leakage: The space between the cylinder and the piston is too large due to wear. If the piston is equipped with a sealing ring, the sealing effect will be lost due to wear or aging of the sealing ring. 3. If only a certain part of the cylinder is often used, the part will be seriously worn, the gap will increase, and the cylinder will leak. At this time, the bore can be reground and the...
