What is the reason for the loud sound of the hydraulic oil tank?

The flow pulsation noise of the four-column hydraulic press, the noise generated by the dead volume (trapped oil), the tooth profile accuracy (tooth profile error and gear pitch error, etc.) is not high, the noise is generated, the air enters and the noise is generated due to cavitation, and the bearing does not rotate. The specific reasons for the evenly generated noise are as follows:
1. The noise caused by inhaling air due to imperfect sealing:
2. The gland and the pump cover have air intake due to poor fit
3. Intake air from the junction of the pump body and the front and rear covers
4. Air intake from the connection of the oil inlet on the rear cover of the pump
5. Air intake from the oil seal of the pump
6. The amount of oil in the oil tank is not enough, and the oil filter or the end of the oil suction pipe is not inserted below the oil level, the oil pump will suck in air
7. The oil return pipe is exposed to the oil surface, and sometimes the air is injected back into the system due to the instantaneous negative pressure of the system.
