The most important function of installing frequency converter is to adjust the speed of AC motor, which has the advantages of good speed regulation effect, multi-performance, safety and reliability, simple operation and universal system. Because of these advantages, it is suitable for many industries and is promoted. Let’s introduce the application fields of frequency converters in daily production.
First, the application of frequency converter in power industry.
Nowadays, China is the second largest power generation country in the world except the United States. In the power industry, inverter products play an important role and run through the whole power generation process. Wind power generation, hydropower generation, coal-fired power generation, slag cleaning and tail gas transportation can all use frequency converters. In addition, in the above systems, only the coal conveying system does not mainly realize its main functions through fans and pumps. The frequency converter can well control the fan and water pump to change the air supply and water supply, adapt to the changes of the system, achieve the effect of energy saving and safety, and ensure the continuous and stable operation of the system.
Second, the application of frequency converter in oil and gas drilling and production industry.
China is a big consumer of oil and gas, and at the same time, it is increasing its exploration and development of domestic oil and gas resources. After entering the Millennium, the oil and gas drilling and production industry has developed vigorously, and the exploration cost has risen sharply every year. In recent years, domestic oil and gas fields with gratifying reserves have been continuously discovered, such as 200 million tons of oil fields in Tahe, Xinjiang, 1 billion tons of oil fields in Nanpu, Hebei, and 500 billion cubic meters of gas fields in Longgang, Sichuan, etc. It is foreseeable that the capital investment in resource exploration will increase in the future. Inverter can be applied to load-type motors in oil and gas drilling and production industry, such as gas compressors, water injection pumps, pumping units, oil transfer pumps, submersible pumps, etc., which can greatly save energy and reduce emissions.
Third, the application of frequency converter in building materials industry.
Real estate is an important industry in China, and materials are needed to build houses, so the building materials industry has a great market in China. The building materials industry is mainly divided into three categories, and frequency converters are mainly used in motors such as pulverizers, blowers, exhaust fans, rotary kilns and conveyors. With the development of technology and ideas, we pay more and more attention to environmental protection, energy saving and emission reduction, so the demand for high-power frequency converters in building materials industry is increasing year by year. The data show that the installation of frequency converter can save about 30% of electric energy, which is a great amount of energy for the whole industry. The utilization rate of some western developed frequency converters has reached 70%, and we are gradually improving to get closer to this value.
Fourth, the application of frequency converter in coal industry.
China’s power generation mainly depends on coal, and it is the largest coal producer in the world. Coal is a non-renewable resource in the short term, and the pollution is relatively large. Now our coal industry is still labor-intensive, occupying more human resources and wasting more, so it needs to be transformed into skill-intensive. If you want to improve the level of automation, you need to develop high technology, and frequency converter is one of them. When used in mine hoists, the energy-saving effect is very remarkable. It can not only improve the automation level and transmission capacity of the motor, but also reduce the consumption of electric energy.
