Calculation
Design of hydraulic cylinders
When designing hydraulic cylinders, the force and speed must be calculated as a function of the existing pressure in the cylinder chamber and the available flow rate.
The permissible values for the working pressure, depending on the pressure series, and the permissible oil speed in the hydraulic ports must be taken into account.
