|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
