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. For this reason, corresponding measures must be taken to reduce or prevent...
