What is a pneumatic circuit?
A pneumatic circuit is an installation made up of pneumatic elements that guide or regulate the air so that the compressed air travels to some actuators. By displacing the air we get mechanical energy.
The main components of a pneumatic circuit are the compressor, the control elements (valves), the actuators and the pipes through which the air will move.
Components to protect and regulate a pneumatic circuit
It is very important that after the compressor we put a filter, a regulator and a lubricator. With the filter we will be able to eliminate the dirt that the air may contain and we will also protect the circuit by purging the condensation of water that could appear from the compressor.
On the other hand, the regulator simply allows us to choose by manual regulation the air flow that we want to pass into our circuit. And finally, the lubricator will provide a ridiculous amount of oil to the circuit, enough to keep it lubricated and optimize its operation.
It should be noted that the incorporation of a pressure gauge to these elements is recommended to visually control the state of the circuit pressure.
Function of pneumatic elements in a circuit
– Compressor: The compressor is responsible for generating the air necessary for it to flow through the ducts or pipes. A dryer is also often placed before the maintenance unit. Its main function is to reduce humidity through refrigeration.
– Control Elements (Valves): These components are responsible for allowing or preventing the passage of air so that the different actuators receive air or not as needed.
– Actuators: The actuators are those that develop the application that is intended for our pneumatic circuit. They are usually cylinders or pneumatic tools.
– Pipes: The pipes are the element in charge of joining the rest of the elements so that the air can flow through our circuit.
