Actuators And Their Uses

The actuator is a device that stops or starts the mechanical equipment through hydraulic fluid, electric current or resources to facilitate movement. 

Actuators can be divided into four basic groups depending on the resources they use are hydraulic, electric, pneumatic or mechanic to generate motion of some sort. If you are looking for the hydraulic actuator then you may check out

Hydraulic Actuator

These actuators transform hydraulic power into mechanical work. The actuator motion will result in possibly rotary, linear or oscillation. hydraulic actuators may be preferred due to the fact that they possessed the ability of high strength and can be used to move heavy equipment.

A small force can produce large force with a hydraulic actuator and yet still capable of providing mechanical rigidity.

An ordinary hydraulic actuator will consist of an empty cylinder that has a piston in it. By pressing and de-stress the piston is made to move to produce motion for mechanical systems.

Electric Actuators

These actuators can be found in the control system due to the fact that they can be easily connected to control systems which are mostly run on electricity as well.

Electrical energy is used for the electric motor which in turn creates a mechanical torque. Because electrical energy does not involve any real substance, one does not need to worry about cleaning such as hydraulic actuators where leaks can occur.
