Pneumatics makes use of an air compressor to reduce the volume of the air in order to increase its pressure. This then moves through a filter into pneumatic tubing, where it’s controlled by valves before reaching an actuator which does the work at the end of the process.

The principles of pneumatics are the same as those for hydraulics, but pneumatics transmits power using a gas instead of a liquid. Compressed air is usually used, but nitrogen or other inert gases can be used for special applications. With pneumatics, air is usually pumped into a receiver using a compressor.

Air compressors work by forcing air into a container and pressurizing it. Then, the air is forced through an opening in the tank, where pressure builds up. Think of it like an open balloon: the compressed air can be used as energy as it’s released.

A pneumatic device is a tool or instrument that generates and utilizes compressed air. Some examples of pneumatic devices are rock drills, pavement breakers, riveters, forging presses, paint sprayers, blast cleaners, and atomizers. An air compressor is one of the major types of pneumatic devices.

Pneumatic device, any of various tools and instruments that generate and utilize compressed air. Examples include rock drills, pavement breakers, riveters, forging presses, paint sprayers, blast cleaners, and atomizers.

A few common examples of things we use in our daily life that contain pneumatic fittings are:

• Bicycle/ball pumps.
• Tire pressure gauges.
• Some nail guns.
• The handicapped-access buttons which operate automatic doors.
• Vacuum cleaners.
• Some car shocks.

Pneumatic Fittings In Everyday Life

• Tire pressure gauges.
• Vacuum cleaners.
• Some nail guns.
• Bicycle/ball pumps.
• The device that slows your screen door down so it doesn’t slam shut when you let go of it.
• The handicapped-access button that opens door for you.
• Some car’s shocks.

Pneumatics takes advantages of the low friction, compressible nature of air. A lot of air can be moved rapidly, and although compressibility needs to be factored in, it can provide an advantage with unmatched response and cycle times.

As such, pneumatics are generally used when much smaller loads are involved. A pneumatic system generally uses an air compressor to reduce the volume of the air, thereby increasing the pressure of the gas. The pressurized gas travels through pneumatic hoses and is controlled by valves on the way to the actuator.

The Advantages and Disadvantages of Pneumatic

• • Easy channeled.
• • Temperature is flexible.
• • The transfer of power and the speed is very easy to set up.
• • Can be stored.
• • Easy utilized.
• •
• • Easy to leak.
• • Potential noise.

Hydraulic System Advantages

• Hydraulic systems are easy to control and accurate.
• Hydraulic systems are simpler and easier to maintain because these systems use less moving parts.
• Only hydraulic systems can deliver constant torque or force regardless of speed changes.
• Easy to spot leakages of a hydraulic system.

Disadvantages of hydraulic system:

• Poor resistance to working fluid pollution;
• Sensitive to temperature changes;
• Hidden danger of leakage;
• Difficult manufacturing and high cost;
• It is not suitable for long-distance transmission and requires hydraulic energy.

Advantages of hydraulic systems include power, accuracy, efficiency and ease of maintenance. But they disadvantages too: they can leak, which makes them messy, and the fluids inside them are often caustic to paint and some seals.

Fluid Power Applications

While fluid power can be used in most any industry or application, it is commonly seen in markets that include packaging, off-highway, mining, offshore/marine, medical, material handling, construction, aerospace, automation, robotics, and entertainment. And fluid power is an important technology.

The Types of Fluids are:

• Ideal Fluid. An ideal fluid is incompressible and it is an imaginary fluid that doesn’t exist in reality.
• Ideal plastic Fluid.
• Real Fluid.
• Newtonian Fluid.
• Non-Newtonian Fluid.
• Incompressible Fluid.
• Compressible Fluid.

There are two basic types of fluid power systems: hydraulic systems, which use liquids such as water and oil, and pneumatic systems, which utilize neutral gases such as air.
