Hydraulic and Pneumatics Installations: What is the Difference?

Hydraulic systems and pneumatic systems are often confusing.

However, you cannot miss the mechanical differences between the two. Both of these systems are critical to the various industries in which they are used.

They also form a crucial component of the performance of the tasks assigned to them. Regardless, hydraulic and pneumatic installations should be carried out by qualified and certified hydraulic engineers with vast experience in the industry.

Sometimes, it can be confusing as to which of the two to choose when you want to install machinery.

The choice of technology to choose depends on the type of task to be accomplished as well as the setting in which the task is to be completed.

On several occasions, these two can be applicable in several different environments and conditions, such as the type of terrain and climatic conditions among other factors.

What are the Similarities and Differences between Hydraulics and Pneumatics

The main difference between the two is the substances they use during operation.

For instance, hydraulics uses highly-pressurised fluid to initiate and accomplish mechanical processes whereas pneumatics uses compressed air or gas.

In hydraulics, force applied on one end can be transmitted to another end using a highly-pressurised, incompressible fluid, which does not vary in volume regardless of the amount of pressure applied. In most cases, the hydraulic fluid used is hydraulic oil, which is incompressible and therefore highly reliable.

The force applied is transmitted or relayed through the hydraulic system to create a force that is 9 times more powerful than the originally applied force.

Hydraulic systems have been designed to invoke a network of pistons, which can range from 1 to several pistons. In this regard, the more the pistons the greater the complexity of the hydraulic system and therefore the greater the amount of force generated from the hydraulic system.

However, despite the numerous distinct differences between hydraulics and pneumatics, there are also notable similarities between the two.

One such similarity is the application of pressure to achieve assigned tasks.

As pointed out earlier, both systems use pressure to get work done but one uses oil whereas the other uses air.

Equipment with a pneumatic system features a set of interconnected parts and compressed air is often injected using an air compressor, sending it through a set of hoses.

Valves are then used to regulate the flow of air.

A pneumatic cylinder transforms the gas into mechanical energy, much like a hydraulic system does to oil under pressure.

Some of the key benefits associated with a hydraulic system include ease of control, a huge amount of force created, hydraulic systems are economical, constant and consistent fluid pressure, and safety, as the typical hydraulic system is enclosed and features limited moving parts.

If you want to perform hydraulic or pneumatic installations, you should consult an engineer or a technician to help you with the decision.

You can find a qualified engineer in your area, whether you live in Kent, Heathrow, Essex, or London. Your choice of system will depend on the task and environment.
