So how is a Pneumatic system or power different from hydraulics? A careful look at both Hydraulic and Pneumatic systems will reveal that they are pretty much functioning under the same principles: mechanical impulses are transmitted when motors compress liquid and carries it through hoses that will activate all moving parts of the system. This is what sets both systems apart from rigid transmission systems. One of the advantages of both Pneumatic and Hydraulic systems from rigid transmission systems is they have more flexible pressure lines. A drive train transmission system only uses a single configuration while air and fluid powered systems can easily channel power through hoses that you can change in shape depending on the need and this makes them quite flexible for many construction projects. 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. By far the biggest difference between the two systems is that Pneumatic systems that use gas is more compressible than Hydraulic systems that use liquid. Also a Pneumatic compressor system makes use of a pump and an air tank with a compressor that only moves when the pressure goes down. Hydraulic systems on the other hand uses compressors that needs to be run all the time since liquid as previously mentioned, is incompressible. Unlike a Pneumatic compressor system, Hydraulic systems have no way to store energy.
Pneumatic and Hydraulic systems are also different when it comes to their exhaust. This is because most Pneumatic compressors make use of surrounding air to keep the system cool. This is problematic in areas or situations where air is not available or if exhausts are not functioning very well. 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.
