||Hydraulic systems are prone to leakage of contaminating fluid and therefore are fundamentally environmentally unfriendly.
||Electromechanical are enviormentally Friendly
||Hydraulic systems are involve large number of parts,so compare to Electro-mechanical its not that much Reliable
||Electro-mechanical systems are simpler and involve fewer parts so are inherently more reliable.
||If not maintained properly, hydraulic systems will run low on fluid which will render them inoperable and may damage or destroy components.
||This is not an issue for electromechanical systems which require no routine servicing.
||The viscosity of hydraulic fluid may vary with temperature, contamination etc. giving rise to performance inconsistencies over time.
||Compare to Hydraulic ,electromechanical will not Vary that much with temprature ,Contamination etc…
||The motors employed in hydraulic are not that much substantial compare to electromechanical.Small, much cheaper high speed motors are often used in hydraulic systems because the fluid acts as a “gearing” medium.
||The motors employed in electromechanical are necessarily more substantial than for hydraulic systems. Mass production, driven by strong demand has rendered electromechanical systems less expensive.
|Ease Of Use
||These are generally not easier to install,Integrate as compare to Hydraulic
||The operating principles of electromechanical systems are obvious and they are generally easier to install being integrated in design and function.
||There is not a single part immeresed in oil bath,Including motor also
||In electromechanical systems, all moving parts are immersed in an oil bath, including the motor.
||Difference in perceptible noise may be acceptable when new but will become more marked in hydraulic systems as components wear.
||High quality electromechanical systems are invariably quieter than their hydraulic equivalent.
||The current sensing circuit will react as quickly as fluid flows through the pipe work.
||The current sensing circuits used in the latest electromechanical systems are more reliable and much faster acting than hydraulic relief valves
