Advantages and disadvantages of Hydraulic Systems

Hydraulic systems are used in situations where higher forces and more precise controls are required.

Hydraulic systems have their merits and demerits.

The advantages of hydraulic systems are

  1. They are more compact.  Mechanical linkages are not required.
  2. They require less maintenance
  3. Hydraulic fluids contain oil.  Hence, they are self lubricating.  
  4. Very precise and smooth movements can be obtained.
  5. They have high reliability
Disadvantages of hydraulic systems

 1. Hydraulic systems are prone to leakages.
2. The leakage of oil causes accumulation of dust particles on the surface.
3.  The parts of the hydraulic system such as seals, gaskets, packings, etc need frequent replacement
4.  The oil is expensive.
