Air compressor
Air compressor
(OP)
Hi Guys,
Today I encountered a problem with our compress air system.
We have 4 30bar 20m3/h sperre piston type motor drive compressor. The problem was with all four air compressor running for for 8 hours only 27 bars of air was maintained.My thought was the compressor are not working properly,but the mechanic disagree and said there is a air leak and there was an air leak.A leak was found on a pipe,but not 80m3/h,so why couldn't the compressor overcome that air leak and build the 30 bar pressure.
This is my thought, the 4 compressor is trying to compressor the 30 bar in the tank but it cant reach that value because every time it try to compress to reach 30 bar the air leak out.please help.

RE: Air compressor
A few dozen small leaks and you would be surprised how much air you loose.

Then once you have PROVEN that they are all working hunt for leaks.
The time does not matter, since the leaks are continuous more time does not help overcome them.

RE: Air compressor
Based on my experiences, it would not be surprising to find that some or all of the individual compressors may be capable of delivering more than their individual nameplate ratings.
Additionally, while you may have leaks in your piping system, your compressed air consuming loads may be drawing more air flow than you are expecting. Metering air flows at carefully selected points in your piping system may prove to be highly beneficial in sorting out your system's true problems.
One of the biggest problems in dealing realistically with plant compressed air systems is that compressed air is very commonly perceived as being "free" when it is actually a relatively expensive commodity.
Valuable advice from a professor many years ago: First, design for graceful failure. Everything we build will eventually fail, so we must strive to avoid injuries or secondary damage when that failure occurs. Only then can practicality and economics be properly considered.
RE: Air compressor
The leak is fairly simple.
More difficult is overcoming hubris to get someone to find the leak.
BUT
Measure the current draw of each compressor, if a compressor is not producing rated volume the current will generally be reduced.
