How exactly are Pneumatic systems different from Hydraulics? Generally speaking, both types of systems function under the same principle and that is the principle of mechanical impulses transmitted when motors compress a substance which is carried through various hoses to the machine itself, causing the parts to move. This is what sets both power systems apart from regular transmission systems. Highly flexible pressure lines are among the many advantages of Pneumatic and Hydraulic systems over rigid transmission systems. The problem with drive train transmission systems is they use only a single configuration to work while Pneumatic and Hydraulic systems that use air and fluid can be channeled through hoses and arranged depending on the need of the user which makes them more flexible. In addition, Pneumatic and Hydraulic systems are known to last a long time unlike drive trains that are known to be subject to wear and damage.
So how are these two systems different? Taking the time to learn about the differences can help you decide which system you are going to use for your construction project. Among the biggest differences between Hydraulic systems that use liquid and Pneumatic systems that use gas is that the latter is more compressible than the former. Moreover, Pneumatic system compressors make use of a pump and an air tank with the compressor that moves only when the air pressure gets too low. A hydraulic system on the other hand has a motor that needs to be run all the time because liquid as we said is incompressible. The reason is that unlike Pneumatic systems, A hydraulic compressor system has no way of storing energy.
Another way that Pneumatic and Hydraulic systems are different is their exhaust. Since most of today’s Pneumatic compressors use an open exhaust system, this means that they use surrounding air to power the tools and release the air after it has done its work. This can cause a lot of problems when the system is used in areas where there is not much air and the exhaust is less than desirable. On the other hand, hydraulic systems are sealed which makes them ideal for underwater work where air is not available and where electrical motors can short out. Considering the cost of buying and even renting a Pneumatic system or Hydraulic system, it is important that you choose the right machines to acquire and a careful study of their differences is imperative as well as a careful consideration of the specific needs your construction project has. This way, you can be sure you are making the right decision.
