Scope Of Application Of Our Inverter Market Analysis
Speed of adjustment, is recognized as the best of AC motor
, speed the most promising programs, in addition to excellent speed performance, the converter also significant Energy The role of technological transformation of enterprises and products are the ideal replacement device speed. Since the 80s of last century was introduced into China since the energy-saving frequency converter for speed process control applications and a more important Automation Equipment, has been rapid development and wide application. In power, Textile And Fiber , Building Materials , Petroleum, chemical, Metallurgy , Municipal, paper, food Beverages And tobacco industries, and public works ( Central air conditioning , Water supply, water treatment, lift, etc.), the inverter are playing an important role.
(1) converter with energy saving Converter is generated by the initial use of speed control, but there is more in the domestic application of energy. China Energy consumption Power, energy efficiency is very low, and insufficient energy reserves. In 2003, electricity consumption in China ,60-70% of power supply, while the total capacity of 580 million kilowatts of electrical capacity in total, less than 20 million kilowatts of electric motor is controlled with variable frequency. According to Industrial Network analysis of market research reports, in China, with changes in load, with energy-saving potential of the motor at least 180 million kilowatts. Therefore, the state vigorously promote energy conservation measures, and focus on recommended frequency control technology.
Application of frequency control, can greatly improve the motor speed control precision, the motor speed in the most energy-efficient to run. With Fans Pumps, for example, under the principles of fluid mechanics, shaft power and speed is proportional to the cube. When the air volume required to reduce, reduce the fan speed, its power decreased by the cube of speed. Therefore, the precise speed regulation Saving Effect is very impressive. Similarly, many changes in the general electrical load demand by the largest production capacity of the motor, so the design margin is too large. In actual operation, light load operation time is very high percentage. Such as the use of frequency control, can greatly improve the light load efficiency when running. Therefore, the change in potential energy load.
As energy-saving purpose inverter used in electric power, metallurgy, petroleum, chemical, municipal, central air conditioning and water treatment industries. To the power industry, for example, lack of electricity as a large area of China, the power Investment Will continue to grow at the same time, the state power to change the cost of power plant control programs on the proposed requirements, lower power consumption within a power plant focus, the frequency converter in the power industry has tremendous potential, especially in high voltage inverter and power inverter. China's industrial market research network report, only the power industry, the inverter market in 2003 reached 250 million yuan. Therefore, energy-saving frequency converter application prospect.
(2) transducer and process control (speed control)
At present, the equipment control level is relatively low compared with developed countries, manufacturing processes and efficiency is not high. But with China's accession to WTO, product quality and production efficiency have to face international Competition Therefore essential to raise the level of device control. As the wide range of frequency control with speed, speed and high precision, and good dynamic response, and in many applications that require precise speed control, the inverter technology is playing to enhance the quality and productivity of the prominent role.
The textile industry as an example, China has the world's largest textile production capacity, market scope of global, industry scale. Textile and chemical fiber industry is the most widely used converter, using the highest density in the industry. In the most common chemical Machinery and equipment , The selected frequency converter equipment screw extruder, spinning machines and post-processing machines. Inverter used more Cotton Device main frame, roving frame, combing machine. These devices require precise speed control, multi-unit or percentage of synchronous transmission synchronous (draft) drive, etc., applications converter can improve the process requirements, improve product quality while reducing manual labor intensity, improve production efficiency, can be said that inverter is the international competitiveness of the textile industry, the importance of enhancing equipment. China's industrial market research network in 2003 converter in the textile and chemical fiber industry in the market more than 10 million.
In addition, food, beverages, Package Loading, paper, Machine tool , Elevators and other industries, domestic firms need to expand production scale, improve production technology, the frequency converter application prospects and development potential are underestimated.
(3) Frequency appliances Addition to industry-related industries, in the ordinary family, save electricity and improve appliance performance, and environmental protection are more and more attention, frequency inverter appliance into another vast market and application trends. Refrigerator with inverter control, Washer , Home air conditioning, etc., in energy saving, reducing the voltage shock, reduce noise, improve control precision, there is a big advantage. At present, China is the world's leading supplier of home appliances, but appliances with the ratio of low frequency converter, while in Japan, more than 90% is a variable frequency control home appliances. According to the survey, in 2003, China's conversion appliances up more than 200%, but reflects the frequency appliances in the market are rare, so conversion has a very good development potential of home appliances.
(4) inverter market prospects in China
China has a huge industrial base, and maintain sustained and steady development; with international standards, many companies need to enhance international competitiveness; the ever-increasing people's quality of life. These are the inverter market growth drivers and the basis for wider application.
2004 China inverter market research report, China's inverter market in the past few years maintained a 12% -20% of high growth, in 2003, due to industrial and Building The rapid development of industry and the industry to invest heavily, then rose to nearly 40% of the market size of more than 55 billion yuan. Into 2004, due to the market in 2003, the base suddenly increased, and the country strengthened the metallurgy, building materials industry, macro-control, inverter market growth will come down substantially. However, the overall Chinese economy and the rapid development of China's accession to WTO, market demand for products will gradually improve and enhance the level of equipment is imperative for production process control of converter will increasingly be adopted, and the other On the one hand, China's power supply and demand imbalance, the peak season limit of gate pull-widespread energy-saving call unprecedented. Therefore, in the next three years, China will remain the inverter market about 10% of rapid growth.
