So how is a Pneumatic system or power 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 systems apart from rigid 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, the gas and liquid used to power Pneumatic and Hydraulic systems help to increase the lifespan of the machines.
If so, then how are these two systems different? Taking the effort to learn about the differences between Pneumatic and Hydraulic systems can help you decide which of them you are going to use for your building projects. One of the biggest differences between a Pneumatic system using gas and a Hydraulic system that use liquid is that gas is highly compressible. 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. On the other hand, the pump in a hydraulic system must be kept running since again, fluid is incompressible. The reason is that unlike Pneumatic systems, A hydraulic compressor system has no way of storing energy.
One way that these tow are different with each other 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. A hydraulic system on the other hand is sealed shut which makes them ideal for underwater work where air is not available and electrical motors can malfunction. 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. Study your options carefully before making a decision.
