An Overview Of Pneumatic Pumps

Pneumatics is a branch of physics, which make use of gases or pressurized air to produce mechanical actions. Their extensive use is found in industries that make use of compressed inert gases to generate mechanical effects. The primary reason behind their usage is that these systems offer more flexibility, low cost and are safe to use. Their major applications are found in construction, dentistry, mining and other areas.

Which Gases Are Used In Pneumatic Systems?

Mostly, compressed air is used in pneumatics, however, gases such as nitrogen and other inert gases can also be used depending upon the applications. In pneumatics, air is compressed into the receiver using a compressor.

What is a Pneumatic Pump?

Pneumatic pump, as we have discussed earlier, make use of compressed air to create momentum which is then used to move fluids through a piping system. Their working principle is pretty similar to hydraulic pumps, the only difference is that, hydraulic pumps use fluids instead of compressed air. Both are capable of creating extreme levels of pressure that can be used to generate large amounts of power.

Working Principle Of Pneumatic Pumps

The working of pneumatic pumps uses a double piston system, with one piston having a large diameter as compared to the other. Between the two systems, there is an airtight chamber which is filled with compressed air or fluids. Since there is no pressure loss between the larger and the smaller piston, the smaller piston receives an amplified level of force which is then used to execute powerful mechanical actions.

What are the Advantages of Using Pneumatics?

Simple to design and operate: Pneumatic machines are easy to design and make use of standard cylinders and other components. Apart from that, they possess simple on-off controls.

Reliable: Pneumatic systems generally have the capability to last longer without any frequent maintenance. Because, gas is compressible, the system is less prone to shocks. Compressed gas can be stored, thus, system will run even when the electric power is lost.

A Safe Alternative: Chances of fire attacks are low in pneumatic pumps which make them a safer alternative to use in industries.

In What Ways Pneumatics and Hydraulics differ from each other?

Both of them can be used depending upon the purposes. However, hydraulics are generally considered apt to be used for large machines. On the other hand pneumatics are good for small things such as robots, cars etc. Also, pneumatics are less expensive and easier to maintain than the hydraulics.

To summarize, due to the reliability and functional controls associated with Pneumatics, they are widely being utilized in industries for several useful purposes. Because of their smaller size, greater precision and lower cost apparatus, they will be appreciated for years to come.
