My past Pumps & Systems columns (read them here) have dealt with using basic engineering principles to better understand the interaction of pump, process and control elements in fluid piping systems....
Second of Three Parts
First of Three Parts
This series discusses the control elements of a piping system, which improve the quality of the product. Part 1 (Pumps & Systems, July 2015) covered passive controls, such as overflow and bypass...
Part one of two: This column discusses valves and fittings and evaluates how these devices affect the operation of piping systems.
Last month's column (Pumps & Systems, February 2014) reviewed the pump selection process and described how many users oversize pumps by adding design margins to account for unknown conditions present...
In 2014, this column focused on improving the operation of piping systems by performing pumped system assessments. The columns have covered energy cost balance sheets, the assessment process and the...
Previous “Pump System Improvement” columns covered the assessment of simple systems with a single load. The system discussed in this column has multiple loads. Figure 1 is a schematic of a piping...
Last month’s column discussed the pre-screening process that identifies and prioritizes systems with a high probability of significant energy savings. After this process is complete, the actual...
When facilities—whether paper mills, refineries, or chemical or waste treatment plants—decide to implement pump system improvements, the first question is always the same: Where to begin? ...
In the previous article calculating the cost of elements in a piping system (Pumps & Systems, July 2014), the energy consumed and power cost balanced exactly to demonstrate the process. Seldom is life...
Last month’s column described the process of creating an energy cost balance sheet for a piping system (see Figure 1). The manufacturer’s curve was used to calculate the cost of operation for the...
