Protect your pumping system from the damaging effects of water hammer

Posted by AuCom on 12/5/16 9:44 AM

Water hammer has the potential to cause significant damage to pumping systems. Most in the pumping industry have a tale to tell about burst or collapsed pipes, or broken or damaged valves, pressure gauges and even pumps.

Solving the water hammer problem requires either mitigating its effects or preventing its occurrence altogether. To this end, there are a number of solutions to consider when designing a pumping system, including electronic motor control.

Electronic motor control devices such as soft starters and variable frequency drives can be used to control the speed of the pump during starting and stopping. This allows for a more gradual increase or decrease in pump speed, preventing water column separation, flow reversal and sudden check valve closure – a few of the primary causes of water hammer.

AuCom's solution for hard-to-start compressors

Posted by AuCom on 5/24/16 10:03 AM

EMX3 retrofit at glass bottle plant - Minnesota

Application:  250HP, 480V, Quincy Compressor for Plant Vacuum

Issue: Repair of competitor’s soft starter that had failed was one option.  But replacement with AuCom’s EMX3 Heavy Duty soft starter chassis unit was a faster and more economical solution.  Even then, this ‘hard to start’ compressor was a challenge!!

Making sense of motor nameplate information

Posted by AuCom on 11/19/15 10:07 AM

A key to clear communication and interoperability is having a shared understanding of the meaning behind terms and phrases. 

The United States motor industry recognises the importance of nameplates using standardised jargon among all manufacturers and has been enforcing usage of the correct terminology for the past 90 years. Using the same terminology and education around the meaning of the terminology has paid off. Having a common motor nameplate language has helped make motors interchangeable and personnel able to correctly understand the specific features of the motor they are installing or replacing.

Are you paying for the perception of flexibility in your system design?

Posted by AuCom on 5/28/15 9:08 AM

With an estimated 80% of electric motor applications being fixed speed processes perhaps it isn’t surprising that variable speed drives are consistently being misapplied. Many motor driven systems are being designed with VSDs to add flexibility that isn’t needed, compromising efficiency while adding to capital and operating costs.

US-based JDA consulting engineers (now part of global consulting firm Exp Global.) offer an interesting discussion of this phenomenon in a blog on the Staticworx website. “As JDA's team commissions large, complex mechanical plants, we find more systems where the VSD is practically abandoned in place. Rather than providing the precise control of flow and pressure or reducing energy consumption and demand, the VSDs appear to be "stuck" at a single speed.”

Why oversizing motors shouldn't be your starting position

Posted by AuCom on 4/2/15 10:10 AM

What are the trade-offs in oversizing a motor for your next application?

Oversizing motors for any particular application is becoming more popular, as engineers seek to provide some ‘insurance’ for a new system. Insurance against possible system failure (and resulting damage to their reputation), and insurance for unanticipated future demands on the application.

An Automation World study on oversizing has asserted that over half of engineers choose to over specify motors. It seems like a ‘no-brainer’ – put in place a motor with plenty of margin of error for rated load, and use a variable speed drive (VSD) to throttle it to meet the system’s actual power needs. Peace of mind guaranteed.
