Pumps: State of Global Efficiency Standards (Part 1 of 2)

Pumps & Systems, Nov. 2015, by Lev Nelik.

"Despite an increasing focus on energy savings around the world, no formal standard—that is also simple and practical—exists. A recent pump energy conference in the Middle East took a comparative look at available resources on the subject in the U.S., Europe, Israel and other areas of the world. Several fledgling documents on formalizing the approach are in the works, but nothing is complete to the point of availability to the pumping community."

System Considerations for VSDs in Industrial Machinery

"The changing landscape of hydraulic drives is leading many fluid power specialists to quickly adapt to VSDs."

Choosing Between Soft Starters & Adjustable Frequency Drives

Pumps & Systems, Nov. 2015, by Nichole Angiola.

"Motors often require large amounts of energy when quickly accelerating to full speed. Using soft starters and adjustable frequency drives reduce in-rush currents and limit torque—protecting valuable equipment and extending the motor's life by reducing motor heating caused by frequent starts and stops. Choosing between a soft starter and an adjustable frequency drive (AFD) often depends on the application, system requirements and cost, both for initial startup and over the life cycle of the system."

System Vibration Monitoring Is Essential to Predictive Maintenance

Pumps & Systems, Nov. 2015, by Mike Pemberton & William Livoti.

"In today's industrial landscape, remote monitoring of rotating assets is critical for reliable operation. Specifically, vibration data from pump bearings and other monitored points allows users to analyze the data spectrum and identify problems, such as shaft misalignment and pump cavitation. The effective use of vibration technology begins within the context of a well-managed predictive maintenance program."

California MSW Organics Digester Prepares To Launch

"Construction is nearing completion, and all the equipment is installed at CR&R Inc.'s high solids anaerobic digester (AD) facility in Perris, California. “We are approaching a dry run with the digester to test out the various system components, and then will fine-tune the process controls,” notes Paul Relis, CR&R Senior Vice-President. “We will likely start processing feedstocks in the digesters in the first quarter of 2016.”"

10 Little-Known VSD Air Compressor Tweaks

Compressed Air Best Practices, Nov. 2015, by Ron Marshall for the Compressed Air Challenge.
http://www.airbestpractices.com/technology/compressor-controls/10-little-known-vsd-air-compressor-tweaks

"The introduction of rotary screw air compressors controlled by variable speed drives (VSDs) is one of the best energy efficiency innovations introduced to the industry in the past few years. This style of compressor control can significantly reduce the energy wasted by compressors running in the unloaded condition. But the type of VSD control offered by various manufacturers can differ, and some of these differences can affect the efficiency of the system. This article discusses some little known tweaks to VSD compressor control, including some using hidden features that can sometimes be implemented to enhance the savings gained by the installation of this type of compressor."

Air Compressor Control for Industry 4.0

Compressed Air Best Practices, Nov. 2015, by Clinton Shaffer.

"We are in the midst of the fourth industrial revolution, or, as it is known in Germany, Industry 4.0. In broad terms, the concept describes manufacturing facilities where all of the machines — including the air compressors, along with their corresponding sensors and air treatment equipment — communicate with each other autonomously, recording performance metrics to a local controller, a wireless network, and an external database. These communicative abilities are enabled by the Industrial Internet of Things (IIoT), in which intelligent, networked devices link everything back to a main data hub."

Managing Multiple-Compressor Systems: Utilizing Controls to Improve Performance

Compressed Air Best Practices, Nov. 2015, by Chad Larrabee.
http://www.airbestpractices.com/technology/compressor-controls/managing-multiple-compressor-systems-utilizing-controls-improve-perfo

"An unmanaged control scheme for a bank of air compressors is a recipe for unnecessary consumption of power, as well as increased or unplanned maintenance. Controlling air compressors with only their on-board controllers can cause one or more of the following problems:
  • Too many compressors are running.
  • The wrong combination of compressors is running.
  • Pressure is higher than it needs to be."

8 Reasons Pumps Operate Off Their Curves

Flow Control, Oct. 30, 2015, by Randy Riddell.
http://www.flowcontrolnetwork.com/8-reasons-pump-maintenance-operate-off-their-curves/

"The plant is having process issues, and the culprit appears to be a process centrifugal pump. The area production manager has asked you to check the pump to see if it is operating on its curve. “Pump won’t pump, make pump pump,” he says. Sounds like a reasonable request. However, other questions need to be answered, such as: Where is the pump running on its curve? If it is not running on its curve, why?"

Calibrate Faster, Smarter & More Accurately [Pump Systems]

Pumps & Systems, Oct. 2015, by Jim Shields.
http://www.pumpsandsystems.com/pumps/october-2015-calibrate-faster-smarter-more-accurately

"As the price of raw materials fluctuates, industries must minimize costs and maximize profit margins. One way to control costs is to become leaner and more efficient. Every time companies remove waste in their processes, they save money. That includes maintenance and efficiency of pumps that move materials through a facility."
