Flexible design is important for the future growth of generic, multivariable transcontinental pump stations.
Consider application and performance requirements to properly select a pressure sensor for any system.
Due to the expense and labor required, most facilities need to maximize the life of their motors. Electrical, insulation resistance and thermal measurement are three tests that can troubleshoot...
Pumps & Systems, April 2008Artificial lift technology selection is highly dependent on the conditions of the wellbore and the specific application parameters of a given well. Electrical...
Pumps & Systems, March 2008Few would dispute that variable frequency drives (VFDs) save energy, but the exact amount depends on the system. Hydraulically speaking, the main difference between a...
Pumps & Systems, September 2007Back in the old days, level control had little or nothing to do with saving energy. In fact, it was often a necessary evil. Today, that is no longer true - the VFD...
Pumps & Systems, August 2007Even when a redundant pumping system is in place, it can be advisable to monitor the condition of the operating units in critical applications where maintaining...
Editor's Note: This is the first part of a two-part series on Process Control. This month we'll look at the P-proportional control-of PID. The second part discusses the I and D. To read...
Pumps & Systems, December 2008Editor's Note: This is part two of a three part series about variable speed pump selection. To read the previous article, click here. To read the next article in...
Pumps & Systems, February 2008The second article of this three-part series on "Dematerializing the Process" explores how future industrial process plants will address rising operating costs plus...
Pumps & Systems, September 2007Why question the PLC? For many, questioning the application of a PLC to the pump station panel is surprising. After all, the pump station panel was once controlled...
Pumps & Systems, June 2008While driving a car with the gas pedal to the floor and then controlling your speed using the brake is obviously inefficient, many facilities use the approach for pump...
Pumps & Systems, April 2007 You have probably noticed that there are several camps out there when it comes to centrifugal pump applications involving variable frequency drives (VFDs). One...
Pumps and Systems, June 2009Adjustable Frequency Drive Application and UseIn the early days of adjustable frequency drive (AFD) technology, the typical application was in process control for...
Pumps & Systems, March 2008Outdated water systems are pumping beyond their original specifications, resulting in inefficient operation, higher maintenance and operation costs and the potential for...
Pumps & Systems, August 2007With the wide use of variable frequency drives in the pump industry and increasing unit size, it is becoming more difficult to design mechanical systems free from...
Pumps and Systems, August 2009One of the major contributors to unbalance in rotating machinery is eccentricity. When we disassemble parts, we must also reassemble them. Even if the reassembly requires...
Pumps and Systems, January 2007Example 1Vertically mounted pumps can resonate as a total structure in a "rocking" mode, as shown in Figures 1 and 2 below. This is one of the toughest unsolved...
