Variable Speed Pumping
In Variable Speed Pumping , you'll learn ...
- Effects of speed variation on centrifugal pumps and positive displacement pumps
- The advantages and disadvantages of using variable speed drives (VSDs)
- Why it’s a mistake to use the affinity laws to estimate energy savings in high-head pump systems
- VSD considerations for retrofits vs. new installations
- How to use a duration diagram to estimate pump energy savings
Significant opportunities exist to reduce pumping system energy consumption through smart design, retrofitting, and operating practices. In particular, the many pumping applications with variable-duty requirements offer great potential for savings.
Most systems requiring flow control make use of bypass lines, throttling valves or pump speed adjustments. The most efficient of these is pump speed control. When a pump’s speed is reduced, less energy is imparted to the fluid and less energy needs to be throttled or bypassed.
In this course the student will learn the benefits of using variable speed drives for flow control. The savings often go well beyond energy, and may include improved performance, improved reliability, and reduced life cycle costs.
