Electric and pneumatic actuators
Depending on the energy carrier used, there are electric, hydraulic and pneumatic drives, or abbreviated as electro, hydraulic and pneumatic drives. The scope of an actuator is determined by analyzing the merits and demerits inherent in each of them. Each of them transfers energy to the actuator and converts it into motion. Each has its own working environment, which makes their characteristics excellent. The choice of the type of drive depends on the initial production resources, its needs, as well as the financial and technical capabilities of the enterprise. The electric drive consumes energy only when driving, which makes it especially economical. A motor of any type - DC, AC, servo motor, etc. can be used.
The air enters the pneumatic drive through the air intake, then it is filtered, compresses with the help of the compressor, then cooled and the already compressed purified cooled air enters the pneumatic cylinder (or other pneumatic motor) and produces the necessary mechanical work.
In hydraulic actuators, the motion of the actuator is carried out by the motion of a liquid (usually mineral oil). There are two main groups of hydrodrives: hydrodynamic and volumetric.
