1.In the hydraulic press system, due to some reason, the pressure of the oil increases sharply in an instant, forming a large pressure value and changing alternately. This phenomenon is called hydraulic shock.
The hydraulic press has the characteristics of large installed power, high working pressure, large flow, and high frequency. In recent years, more and more attention has been paid to the research on energy-saving technology of hydraulic presses, and green energy-saving is also one of the development trends of a hydraulic press.
The working oil of the hydraulic press is recommended to use No. 32 and No. 46 anti-wear hydraulic oil, and the oil temperature is in the range of 15 to 60 degrees Celsius. The oil of the hydraulic press is strictly filtered before it is allowed to be added to the oil tank. The working oil should be replaced once a year, and the first replacement time should not exceed three months.
