Tonnage Calculation And Pressure Of Hydraulic Press

Definition of pressure: in hydraulic transmission, the normal force acting on the unit area of liquid under static state is called pressure;
1kgf/cm2≈1bar=105Pa=0.1MPa
Measurement of pressure: pressure is divided into absolute pressure and relative pressure. The pressure measured based on absolute vacuum is absolute pressure;
Absolute pressure=atmospheric pressure+relative pressure=atmospheric pressure+gauge pressure
Transmission of pressure in the liquid: the transmission of pressure in the hydraulic system follows the Pascal principle (the pressure in the static liquid is equivalent to each point in the liquid) - the pressure in the closed container is equal everywhere;
Relationship between pressure and load: F=p × A
F -- Load (tonnage)
P - pressure
A -- Acting area of liquid
