Actuator

What is actuator??

-Actuator is a mechanical device for moving mechanisms or systems

There are 5 type of actuator:

1.Electric Actuator

-Powered by motor that converts electrical energy to mechanical torque

-Used to actuate equipment such as multi-turn valves.

-Cleanest and most readily available forms of actuator because it does not involve oil.

2.Pneumatic Actuator

-Converts energy formed by compressed air at high pressure into either linear or rotary motion

-Pneumatic energy is desirable for main engine controls

-Can quickly respond in starting and stopping as the power source does not need to be stored in reserve for operation.

3.Hydraulic Actuator 

-Consists of a cylinder or fluid motor that uses hydraulic power to facilitate mechanical operation

-The mechanical motion gives an output in terms of linear, rotary or oscillatory motion because liquid is nearly in compressible, a hydraulic actuator can exert considerable force, but is limited in acceleration and speed.

4.Mechanical Actuator 

-Functions by converting rotary motion into linear motion to execute movement

-It involves gears, rails, pulleys, chains and other devices to operate

5.Electraulic Actuator 

-combination of hydraulic, electronic and mechanical technologies to achieve state-of-the-art design for Linear, Rotary and Drive actuator.Electraulic Actuation is the patented Flow Match System. 

-This technically-advanced hydraulic circuit control the magnitude and direction of the actuator and result a smooth motion, exact positioning and instantaneous response.
