Pressure drops in a compressed air system can occur for a variety of reasons. Some common causes of pressure loss include:
Leaks: Leaks in the compressed air system can cause pressure drops by allowing air to escape from the system. Leaks can occur in pipes, fittings, valves and other components of the system.
Restrictions: Restrictions in the compressed air system can cause pressure drops by restricting the flow of air. Examples of restrictions include clogged filters, partially closed valves and restricted piping.
Improperly sized piping: If the piping is not properly sized for the flow rate, it can cause pressure drops in the system.
Air dryer: If the air dryer is not working properly, it can cause pressure drops in the system.
Corrosion: Corrosion in the pipes, fittings and other components of the air system can cause pressure drops by reducing the internal diameter of the pipes and fittings.
Excessive use of compressed air: If the compressed air system is used more than it was designed for, this can cause pressure drops.
Insufficient compressor capacity: if the compressor does not have sufficient capacity to meet demand, it can cause pressure drops in the system.
Incorrectly set pressure regulators and control valves: If the pressure regulators and control valves are not set correctly, this can cause pressure drops in the system.
Piping and clearances: Improperly selected pipe diameters and long pipes will cause pressure drops, especially at high air flow rates.
It’s important to regularly check and maintain the compressed air system to identify and correct any potential problems that could cause pressure drops. This includes checking for leaks.
