Pneumatic Circuit Examples PDF

Pneumatic circuits are used in a wide variety of applications, from simple to complex. This article provides examples of pneumatic circuits for a variety of applications, including: *

Controlling a valve

*

Moving a piston

*

Driving a motor

*

Generating air pressure

*

Providing power to a tool

Each example includes a diagram of the circuit, a description of how it works, and a list of the components used. ### Controlling a valve The simplest pneumatic circuit is a valve control circuit. This type of circuit uses a valve to control the flow of air to a device. The valve is typically controlled by a switch or a sensor. The following diagram shows a simple valve control circuit:

In this circuit, the valve is controlled by a pushbutton switch. When the switch is pressed, the valve opens, allowing air to flow to the device. When the switch is released, the valve closes, stopping the flow of air to the device. ### Moving a piston A pneumatic piston is a device that can be used to move objects. Pneumatic pistons are typically used in applications where a lot of force is required, such as in industrial machinery. The following diagram shows a pneumatic piston circuit:

In this circuit, the piston is connected to a cylinder. When the air valve is opened, air flows into the cylinder, pushing the piston up. When the air valve is closed, the air in the cylinder is trapped, keeping the piston in place. ### Driving a motor A pneumatic motor is a device that can be used to drive a shaft. Pneumatic motors are typically used in applications where a lot of torque is required, such as in construction equipment. The following diagram shows a pneumatic motor circuit:

In this circuit, the motor is connected to a gearbox. When the air valve is opened, air flows into the cylinder, driving the piston up. The piston drives the crankshaft of the gearbox, which in turn drives the motor shaft. ### Generating air pressure A pneumatic compressor is a device that can be used to generate air pressure. Pneumatic compressors are typically used in applications where a high pressure of air is required, such as in air tools. The following diagram shows a pneumatic compressor circuit:

In this circuit, the compressor is connected to a reservoir. When the air valve is opened, air flows into the compressor, where it is compressed. The compressed air is then stored in the reservoir. ### Providing power to a tool A pneumatic tool is a tool that is powered by compressed air. Pneumatic tools are typically used in applications where a lot of force is required, such as in construction or maintenance. The following diagram shows a pneumatic tool circuit:

In this circuit, the tool is connected to a hose. When the air valve is opened, air flows through the hose and into the tool. The air drives the motor of the tool, which in turn drives the tool's mechanism. These are just a few examples of pneumatic circuits. There are many other types of pneumatic circuits, each with its own unique purpose. By understanding how pneumatic circuits work, you can design and build pneumatic systems that meet your specific needs. ## References * [Pneumatic Circuits: An Introduction](https://www.engineering.com/mechanical/pneumatic-circuits-an-introduction) * [Pneumatic Circuits: Design and Applications](https://www.engineering.com/mechanical
