Energy saving and environmental protection China's frequency converter market will be stronger all the way

China's frequency converter market is currently in a period of rapid growth and is widely used in air conditioning, elevator, metallurgy, machinery and other industries. According to statistics, China's inverter market has maintained a growth rate of 12% - 15% in the past few years, which has far exceeded the GDP growth level in recent years, and will maintain a growth rate of more than 10% in the next five years at least. Considering the price drop of about%, the installed capacity (power) of frequency converters in the Chinese market actually increases by about 20%. According to this development speed and the demand of the Chinese market, the market will be saturated and gradually mature at least 10 years later. Therefore, China's inverter market has broad development space

energy conservation and consumption reduction are the top priority.

during the two sessions, industry representatives and members believed that "the current energy problems in China are more" bottlenecks "than" crises " Energy tension is relative, not absolute. China is short of energy per capita, and its structure and distribution are extremely unreasonable. Energy waste and environmental pollution caused by the limitation of technology level and production capacity have become increasingly prominent problems. Therefore, the rational development and use of energy needs an overall process

energy saving and consumption reduction. Frequency converters play a great role

reducing energy consumption is not simply energy saving. It involves all links from energy mining, processing to downstream energy use

this requires us to improve the efficiency of energy development, production and processing and reduce waste; We should adopt advanced technology, equipment and products that save energy, reduce consumption, save water and protect the environment, and transform or eliminate backward production capacity, processes and products with high consumption and heavy pollution. Among them, there are huge opportunities for automation enterprises, and the most direct one is the frequency converter manufacturer. From upstream oil, natural gas and coal mining, to energy transmission and power generation, to downstream petrochemical, steel and automobile production, to later water treatment and environmental protection

the original purpose of frequency converter is speed control, which is used in printing, elevator, textile, machine tool, production line and other industries. At present, a considerable number of applications are aimed at energy conservation. As China is a large energy consuming country, its energy utilization efficiency is relatively low, and China's energy reserves are relatively poor, the state vigorously advocates various energy-saving measures, and the State Economic and Trade Commission and the State Planning Commission formulated the administrative measures for saving electricity in 2001, focusing on the frequency converter speed regulation technology. In the fields of water pump and central air conditioning, the frequency converter can replace the traditional flow limiting valve and reflux bypass technology to give full play to the energy-saving effect; In the thermal power, metallurgy, mining and building materials industries, the economic value of AC motor system with high-voltage variable-frequency speed regulation is being reflected

Mr. xieruixin, marketing director of Rockwell Automation Greater China, a world-famous auto lightweight enterprise, once said "With the rapid development of domestic industry, power, coal and other energy sources are in serious shortage. As a partner of many large domestic power, steel and even automobile and water treatment enterprises, we not only provide them with appropriate products, but also bring our mature industry experience and solutions to them to help them reduce energy consumption, increase output value and protect energy and environment." Dr. huangjianzhong also said: "Energy saving is a must for every industry. After using our special frequency converters for fans and water pumps, some large domestic iron and steel enterprises have adjusted the production speed, optimized the production process, and achieved excellent energy-saving results. In other industries, we also have many successful cases, such as our Shandong Huangdao Power Plant four boiler negative pressure ventilation system drive device transformation project, which reduces the power consumption of Huangdao power plant every year The output is 30million kwh, saving 1.2 million US dollars. What are the performance characteristics and operating environment of our medium voltage variable frequency gas spring performance testing machine? Now let's analyze one by one: the reactor solution helps Daqing Refinery reduce energy consumption by 41% every year. We helped Liuzhou Iron and steel company to carry out the transformation of blast furnace control system, which increased the output value of steel production by US $570000 per month. "

domestic enterprises are ready to take off

in response to the market demand for energy conservation and environmental protection, domestic frequency conversion enterprises have sprung up in recent years, but few enterprises are famous for product quality. According to insiders, at present, compared with foreign frequency conversion enterprises, several domestic enterprises that are at the top of the technology have a very competitive advantage. The product design of domestic enterprises has a variety of index requirements suitable for domestic users. For frequency converter products with comparable performance, the price of foreign products is higher than that of domestic products, and foreign enterprises are more expensive in terms of after-sales service, The disadvantage of most domestic enterprises lies in the lack of funds, so they can not greatly expand the market. I believe that with the further improvement of users' awareness of energy conservation and environmental protection, after twoorthree years of self-development and growth, domestic enterprises will catch up with and surpass foreign enterprises and occupy a larger share of the domestic market

according to market research, there are at least 180million kW of domestic motors with variable load and energy-saving potential in China. It can be seen that the demand for energy saving and consumption reduction raised by energy shortage provides a broader space for the application of inverter, and also brings more development opportunities to inverter enterprises
