Most facility’s compressed air systems have evolved over time. A spur added here a spur added there. Eventually pressure drop issues develop. Common practice is to increase the air pressure at the compressor. While it may address the symptom it does not address the problem and is very costly. For every 2 PSI increase in pressure requires 1% more energy.
A properly designed system will be a loop with spurs. This will ensure all air
drops will share the air equally. The header loop should be able to carry all the air the compressor is capable of producing. Best practices suggest the distribution header should be sized to allow an air velocity not to exceed 30 ft/second. The formula to calculate this is:
A = 144 * Q * Pa
V *60 x (Pd +Pa)
Pipe Diameter = √ (A*4/3.14)
Where:
A = cross sectional area if the pipe bore in square…

How to do Electrical Troubleshooting of Electrical Motor Control Circuit
This video uses http://www.bin95.com/ Electrical Troubleshooting Simulation software to teach you how to troubleshoot an electrical motor control circuit. At the end is just an example how our software uses realworld workorder system to track student while doing electrical troubleshooting with our simulation software, and the detailed analysis report. (helps student learn better ways to troubleshoot.)
