Linear actuators in hydraulic and pneumatic systems are responsible for converting hydraulic or pneumatic potential into a linear force.
In a pneumatic linear actuator, compressed air puts pressure on the surface of the piston and a force equal to the product of the effective surface of the piston by the pressure is created.
This linear force is directed out of the actuator by the piston rod (ROD), which is generally used to move the object connected to it.
Considering that the maximum pressure of compressed air used in pneumatic systems is generally 10 Bar (in workshops and factories), therefore, in order to achieve more power in pneumatic actuators, the effective level of the piston must be increased.
Increasing the effective area of the piston increases the dimensions of the actuator. If we need high force with small dimensions, we have to use hydraulic actuators.
The movement course of the actuator is another main parameter of the actuator.
By using valves or flow rate control mechanisms, the amount of movement of the actuator can be controlled. The output force of an actuator can be controlled by using pressure control valves.
The required amount and type of movement can be created by using crank or gearbox mechanisms at the output of the actuator.
Based on the customer’s needs, this company has the ability to design, reverse engineer and manufacture all kinds of linear actuators and has valuable experiences in this field.
