What is the advantage of hydraulic oil

  • Large power density, large forces and torques can easily be transmitted with a small construction volume.
  • Infinitely variable adjustment of speed, torque and force over a wide range
  • Movements under full load possible from a standstill.
  • Distributed construction enables:
    • optimal structural adaptation of the hydraulics to space requirements,
    • high efficiency through central drive systems and decentralized use of hydraulic energy,
    • parallel operation of linear and rotary output elements in one hydraulic system.
  • Easy integration of the overload protection.
  • Easy energy storage in the system.
  • Suitable for fast movements as well as for extremely slow precision movements.
  • The compressibility of liquids can lead to pressure and movement oscillations, which can result in switching shocks and uneven movements.
  • The friction of the fluid in the system (lines, nozzles, etc.) results in a loss of performance.
  • Lower efficiency of hydraulic systems compared to mechanical drives.
  • The manufacture of hydraulic devices places high demands on the accuracy of the manufacturing and assembly processes.
  • Problem of leakage and gap losses in hydraulic systems, e.g. due to changes in viscosity as a result of temperature changes.
