WHAT ARE ADVANTAGES AND DISADVANTAGES OF HYDRAULIC SYSTEM?

Advantages

• The hydraulic system uses in compressible fluid which results in higher efficiency.  
• It delivers consistent power output which is difficult in pneumatic or mechanical drive systems. 
•  Hydraulic systems employ high density in compressible fluid. Possibility of leakage is less in hydraulic system as compared to that in pneumatic system. The maintenance cost is less. 
• These systems perform well in hot environment conditions. 

 Disadvantages 

•  The material of storage tank, piping, cylinder and piston can be corroded with the hydraulic fluid. Therefore one must be careful while selecting materials and hydraulic fluid. 
•  The structural weight and size of the system is more which makes it unsuitable for the smaller instruments.
•   The small impurities in the hydraulic fluid can permanently damage the complete system, therefore one should be careful and suitable filter must be installed.
•   The leakage of hydraulic fluid is also a critical issue and suitable prevention method and seals must be adopted.
•   The hydraulic fluids, if not disposed properly, can be harmful to the environment.
