The system is used in rubber calendar to control operation of cylinders.
Pressure of the system is maintained by accumulator. Sensors monitor the pressure and send out signals to automatically maintain it. Due to the long time of consistent pressure, the motor does not need to work frequently. Thus, life span of the components is expanded, heat of the system is cut, and energy cost is reduced. Various display and safety measures are applied in the system, monitoring all key parts’ pressure. Safety valves are installed in parts that may endure hydraulic impact.
