摘要

Pumps consume about 15% of all electricity generated world wide. In the USA alone this accounts for over 130 TWh per annum. A saving of only 1% would amount to $80 million in electricity cost. The importance of energy saving, in pump systems, to individual organisations is not always realised and purchase price and maintenance cost may be considered to be more important. This is partly due to the split of responsibilities for capital expenditure, reliability and energy cost and partly due to a lack of appreciation of how savings can be achieved. When all elements of life cycle cost are considered it will often be seen that energy consumption by pumps is the largest single expenditure. Reducing energy usage for pumps is much more than improving pump efficiency. Pump users and manufacturers can make significant savings by attention to system design, pump specification, drivers, pump control, auxiliary services and refurbishment policy.
