离心式压缩机–电动机拖动
About 70% of industrial power is used to power motors, and 45% of global power is used to drive motors in building and industrial applications. It is also estimated that if about 300 million industrial motors still in operation are replaced with high-efficiency equipment, the global power consumption will be reduced by as much as 10%.
China's overall development has changed from the pursuit of development speed and volume to the pursuit of development quality and efficiency. Under this trend, we believe that more and more customers are willing to invest in efficient motors. We advocate the matching use of frequency converter and motor, because when the frequency converter and motor are combined, the energy consumption of fans and pumps can be reduced by at least 25%. With the progress of digital technology, we can optimize the energy efficiency of the whole drive chain from the frequency converter to the load end through big data analysis.
In China, by the end of 2020, we have delivered more than 10 million frequency converters and high-efficiency motors to customers, saving more than 475 billion kwh of electricity, equivalent to reducing CO2 emissions by about 470 million tons. The electricity saved is equivalent to the electricity consumption of Beijing in four years.
Intellectualization and digitization are the future development direction of the manufacturing industry. Since the beginning of this year, what products and solutions have ABB China's Motion Control Division launched that make the market bright? What are the key industry cases to share?
We have delivered more than 10 million motors and frequency converters in China, so how to connect these devices to the Internet is our first task.
As for digital and intelligent manufacturing, different enterprises have different strategies and directions. For ABB's China motion control business unit, we have delivered more than 10 million motors and frequency converters in China, so how to connect these devices to the Internet is our first task. At the same time, we are actively looking for leading enterprises in various industries to cooperate and jointly develop digital solutions for the industry. In addition, the digital development is also closely related to the establishment of the channel network, so we are actively developing and improving the digital channel network coverage. With the continuous growth of local enterprises, their response speed may be faster. Under this competitive situation, how will ABB bring its innovative achievements to the market faster? Adhering to the customer-oriented principle and creating more value for customers has always been our focus.
ABB motion control has been doing business in China for more than 25 years, so we are very adapted to the speed of China. Our business development has been synchronized with the development of China, and we are committed to shifting our focus from sales and manufacturing to R & D, innovation and digitization. What are the business priorities and development strategies of ABB motion control for the coming 2022? In 2022, abb motion control will always adhere to the customer-oriented principle and continue to vigorously develop major strategic projects. Based on the current fluctuating market situation and the repeated epidemic situation, there are still many uncertainties in the market. In 2022, abb motion control will always adhere to the customer-centric principle and continue to vigorously develop major strategic projects. In the future, we will continue to seize every possible market opportunity, constantly develop new customers and new applications in various industries, strengthen product and technology innovation, improve production efficiency, constantly consolidate the stable recovery trend, continue to implement the concept of energy conservation, efficiency efficiency and low-carbon emission reduction, and promote the transformation of society and intelligent manufacturing. 1.
