Optimising pump and fan applications
Pump and fan applications account for around 38 per cent of the end uses of motive power in industry.
In pump and fan applications, the power consumed is proportional to the operating speed cubed. Efficiencies of pumps and fans vary greatly and depend on operational requirements. Fine-tuning the system can have a big impact on energy consumption. You should keep in mind that although your pump (or fan) and your system are two separate entities, they are totally dependent on each other. Changing one will have a significant impact on the performance of the other.
The key areas where fluid energy is most commonly wasted are:
- excess head (pressure) that must be throttled
- more flow than necessary to accomplish the purpose of the system
- unnecessary flow paths
- excessive frictional losses.
Motors Solutions Online contains an assessment framework to help you identify the opportunities on your site that require the least amount of effort. You can also contact your suppliers and manufacturers of pumps, fans and control equipment such as variable speed drives, to find out what additional support they can offer.
