![]() If you attempt to raise the pressure at the discharge of the tube, the flow increases and the pressure will not rise at the discharge as fast as it does at the inlet to the tube. copper tube at 90 PSIG will be less than 40 SCFM because the pressure will drop to 35 PSIG in the tube. To understand how leaks work in a compressed air system, let’s look at the impact of a leak from a systemic point of view. The flow through a leak is similar to an orifice in that the flow is determined by the pressure immediately upstream of the opening. The pressure drops in the line supplying air to the leak based on the line’s ability to support the rate of flow.įor example, the air flow across a ¼ inch orifice at 90 PSIG is 94 SCFM but the flow through ten feet of ¼ inch I.D. What Causes a Leak in a Compressed Air System? Longer runtimes and demands increase maintenance needs too. As a plant deals with reduced equipment life, they typically spend more time and money on maintenance as well. Usually, facilities with high air leakage need to replace their compressed air systems more regularly. The compressor then must cycle more frequently and run longer, which reduces the useful life of the system. The overall system life is reduced since leaks put a higher air demand on the compressed air system than what is actually needed. Your machine can suffer in a few different ways if it is leaking. One more area that gets hurt by leaks is the air compressor itself. Plus, if leaks cause a loss in production time, you may have to spend more on additional production equipment to increase production capacity. This addition increases your electricity bill and can wear out your system more quickly.
