Compressed Air Best Practices - March 2009 - (Page 13) Focus Industry ENERGY MANAGEMENT | 03/09 | ® The drawing and plating machines in HP are all lower pressure applications. Pictured to the right is a typical regulator that is installed on most HP end-use equipment. It is scaled in MPa (megapascals). A .4 to .5 MPa setting equates to 58–72 psig. Barring a major supply-side failure, HP area will never be impacted or have issues relating to pressure. Even the diaphragm pumps can operate at lower pressures. FP is the area of production where low pressure could cause an occasional disruption. Due to the undersized pipe, the given flow to FP creates a 7–8 psig gradient (from dry receiver to end users). The chart shows an average pressure of 93 psig in FP. When diaphragm pumps come online, such as the trash pumps, LL (liquid lubricant) or HCL pumps, we see the pressure draw-down very easily. The draw-down lasts as long as the pump is online and then the pressure recovers. A key finding here is that given a different combination of compressors, the pressure drop was not that extreme. This would lead us to believe that the pressure drops can be cured with the right mix of compressors online. Piping issues still are a threat to stabilizing pressure, but the supply side is still the bigger impact. FP’s pressure concern is in the rewinding area. We measured pressure at the furthest machine, which was FGW-10. The regulator at each rewinder is set for .5 MPa, which is 68 psig. High-speed data logging proved this. This is at least 20 psig lower than the lowest pressure recorded during the seven days of logging. Only a compressor failure could cause the pressure in FP to drop and impact this area. Additionally, the safety switch is set at 58 psig or .4 MPa and this pressure will probably never be reached. www.airbestpractices.com 13 http://www.donaldson.com http://www.donaldson.com http://www.airbestpractices.com http://www.airbestpractices.com
