Red Seal Industrial Mechanic (Millwright) Practice Exam

What are the primary components of a pneumatic system?

1. Motor, actuator, gears, and chains.

2. Compressor, actuator, valves, and piping.

3. Pump, filter, valves, and tubing.

4. Fan, sensor, controller, and exhaust.

The correct answer is: Compressor, actuator, valves, and piping.

The primary components of a pneumatic system focus on the transfer and control of compressed air to perform work. A pneumatic system typically includes a compressor, which generates compressed air, and an actuator that converts this air pressure into mechanical motion. Valves are essential for controlling the flow and direction of the compressed air, allowing for precise operation of the actuators. Piping is necessary to transport the compressed air throughout the system, connecting the compressor to the actuators and valves. Understanding these components is crucial for anyone working with pneumatic systems. The compressor is the starting point where air is compressed, and the actuator performs the physical work. Valves provide the necessary control mechanisms, while piping ensures that all components can efficiently work together. This arrangement is fundamental to the operation of pneumatic systems in various applications, from automated machinery to assembly lines.
