“A pneumatic system is a type of power transmission system that uses compressed air or gas to perform mechanical work. These systems are widely used due to their simplicity, reliability, and cost-effectiveness compared to hydraulic and electrical systems.”
Key Components of a Pneumatic System
(Infographic: Breakdown of components with labeled animation)
Air Compressor – Generates compressed air.
Reservoir/Tank – Stores compressed air for stable operation.
Pressure Regulator – Controls air pressure to prevent damage.
Valves (Directional, Flow, Pressure Control) – Direct and regulate air movement.
Actuators (Cylinders, Motors) – Convert air pressure into mechanical motion.
Piping and Fittings – Transport air within the system.
Filters and Lubricators – Ensure clean, moisture-free air for smooth operation.

[HOW DOES A PNEUMATIC SYSTEM WORK?]
🎙️ Voiceover:
“The working principle of a pneumatic system follows a simple energy conversion process. Compressed air is stored in a reservoir, regulated, and directed through valves to actuators, which generate motion.”
Working Steps:
Compression: Air is compressed by an air compressor.
Storage: Compressed air is stored in a tank or receiver.
Control: Regulators and valves adjust pressure and flow.
Actuation: Cylinders or motors move based on controlled airflow.
Exhaust: Used air is expelled after performing work.

A pneumatic system is a type of power transmission system that uses compressed air or gas to generate mechanical force and motion. It’s a versatile technology used across many industries due to its simplicity, reliability, and cost-effectiveness compared to hydraulic and electrical systems.

Here’s a breakdown of the key aspects:

How it Works:

A pneumatic system works by compressing air, storing it under pressure, and then using that pressurized air to power actuators (like cylinders or motors). Valves control the flow and direction of the compressed air, allowing for precise and controlled movement. After the work is done, the used air is exhausted.

Key Components:

Air Compressor: Compresses atmospheric air to create high-pressure air.
Reservoir/Tank: Stores the compressed air, providing a stable supply.
Pressure Regulator: Controls and maintains the desired air pressure.
Valves: Direct and control the flow of compressed air. There are various types, including directional control valves, flow control valves, and pressure control valves.
Actuators: Convert the compressed air energy into mechanical movement. These can be pneumatic cylinders (linear motion) or pneumatic motors (rotary motion).
Piping and Fittings: Connect the components and transport the compressed air.
Filters and Lubricators: Clean and lubricate the compressed air to prevent damage and ensure smooth operation.

Types of Pneumatic Systems:

Pneumatic systems are categorized based on actuation type, pressure levels, and application:

Actuation Type: Single-acting (uses air pressure in one direction, return is spring-powered) and double-acting (uses air pressure in both directions for more precise control).
Pressure Levels: Low-pressure (up to 1.5 bar), medium-pressure (1.5 to 10 bar), and high-pressure (above 10 bar).
Application: Industrial automation, medical, aerospace, and more.
