System Assessments

Analysis of the pressure data logging showed that, while the variable speed drive compressor maintained a constant discharge pressure near 120 psi, the pressure at various critical points fell to as low as 85 psi during peak production operations. General pressure in the plants, especially Plant 2, fluctuated between 102 and 112 psi, showing that the pressure/flow control valve was not regulating properly, and that Plant 2 lacked enough general storage volume to support transient flows.  

Small Piston Air Motors Save Big Energy While Ensuring Safety

Vane motors can run at much higher speeds (2000 rpm and up), but piston motors tend to turn much slower – less than 1000 rpm. For slower speed applications, vane motors are mated with a gear reducer and called a gearmotor. The gearmotor can produce the higher torque and slower speed needed for some applications, but the gear reducer can add some drivetrain loss. While a piston air motor may not be able to replace a vane motor where high speed is needed, it can be a good choice for high torque/low speed applications.  

Air Compressor Control Lessons Learned at Metal Products Company

Their system was designed and built to achieve premium performance, yet in a recent compressed air assessment the numbers showed their system had surprisingly poor performance, and worse, their staff was unaware of the problems. This article discusses some of the challenges faced and some future solutions that could get their system back to higher performance levels.

When Three Air Compressors Are Better Than One (or Two)

During Dealer Week, they needed enough compressed air to power multiple machines at a time all day long. Keeping simultaneous demos running for all their top machines required airflow of up to 400 cubic feet per minute (CFM). However, outside of Dealer Week, their compressed air demands were quite modest. On a typical day, they only needed 20 CFM to power their dust collection system and pneumatic tools for their dock and warehouse crating areas. 

Five Decades of Innovation at Festo USA

The history of Festo began in 1925 in Germany. Festo USA was founded on March 15th, 1972 in Port Washington on Long Island, with the focus of being a full-line supplier of pneumatics – a focus we continue with today.

Boosting Process Vacuum Performance at a High-Tech Electronics Plant

Electronics applications typically run their tooling requiring Process Vacuum based on differential pressure from barometric; that is, they control their PVAC pumps to “Inches of Mercury Vacuum”. This is because the parts and pieces being manipulated by vacuum are of certain sizes, shapes, and weights. If the differential pressure across the part is not great enough, then the tooling will fail and result in a loss of product, adverse impact to quality, and production downtime. 

DOE Better Plants Partners Get Serious About Compressed Air Systems

Compressed air is used in all the company’s plants and is often the single largest energy end use within them. As a result, compressed air energy-saving measures are often replicable across the company and offer significant positive impacts. One area of focus is with compressed air leaks since they are “the best low hanging fruit to focus on and they always keep popping up and waste energy”.

What is CFM in Compressed Air? How Much Do I Have? How Much Do I Need?

Do the questions in the title seem like simple questions? There are many things that confuse the issue including air compressor condition, controls as applied, interconnecting pipe size and configuration and effective storage. All of these have been covered in many technical compressed air papers and articles. The topic many don’t use or understand is how to calculate the actual value of these initial questions at the operating sites and conditions. 
 

Moisture: the Assassin in Compressed Air Installations

Moisture can freeze in compressed air systems and cause rust and pitting in pipes and components. It can also flush out the lubricant resulting in accelerated tool wear and damage to valves and cylinders. Moist air is also a rewarding breeding ground for bacteria, which especially in the food and pharmaceutical industries can lead to product rejection and costly production downtime. It is therefore strange that many companies limit themselves to measuring only basic quantities such as pressure, flow and (absorbed) power.
