UK energy saving potential in the electrical industry reaches £600 million

According to a recent report from the Carbon Trust, British industries can save more than £630 million by using more efficient motors and variable speed drives (VSDs).

The report proposes that the potential of the industry in saving annual energy expenditure is so great. Take the industry as an example. By using VSDs high-efficiency motors, a medium-sized company with an annual electricity charge of 50,000 pounds can save 5,000 pounds. Equipment such as fans and pumps do not always operate at full capacity. By using VSDs, 50% of energy consumption can be saved.

Motor energy consumption accounts for 2/3 of the UK's total electricity consumption, which accounts for about 40% of the world's electricity consumption. The annual operating cost of one motor is equivalent to the purchase cost of 10 motors.

The report of the Carbon Trust also pointed out that the UK food and beverage industry can save nearly 70 million pounds of expenditure annually through the installation of variable speed devices and high efficiency motors. Other industries such as plastics, rubber and chemicals can save up to 270 million pounds in annual expenditures.

The head of the carbon trust agency said that if the industry chooses the right motor and drive method, the cost savings can be up to 640 million pounds. Of course, it is sometimes easier to take a side view, but in fact a simple step can bring about tremendous changes. Adopting the measures in the report will directly affect the development of the industry.

Here are some of the highlights of the report:

1. Set the time point: Set the shutdown point for the motor-driven device at some specific time if the device does not need to be used.

2. Check motor idling: Observe whether the motor-driven equipment will idle when it is suspended or replaced.

3. Use VSDs technology: Reduce the fan or pump from 100% load to 80%, saving 50% of energy use.

4. Minimize system requirements: Carefully analyze requirements to minimize equipment output, such as temperature or pressure settings.

5, verify the performance of the entire system, so that each component is operating in the best condition, including:

(1) Make sure that the equipment is regularly checked: Clean the motor and Auxiliary Equipment regularly to remove dirt and impurities.

(2) Check the status of the motor to ensure proper installation and good heat dissipation conditions.

(3) Check if the motor and equipment are in balance and the pulley is tight.

(4) Observe regularly and check whether the sound is normal and whether it leaks oil.

(5) Use suitable lubricants and replace them regularly.
