Inverter: inverter technology to energy-saving weapon
"Since October last year, our company has carried out frequency conversion and energy-saving renovation on the emulsified pump station and the main ventilator. According to the calculation, nearly one million yuan of energy-saving benefits will be realized in one year." Recently, when interviewed by a reporter, Henan Energy Xinyi Mining Co., Ltd. The official told reporters. It is understood that the company emulsification pumping station energy-saving transformation projects and the main fan inverter energy-saving projects, a total investment of more than 260 million. During the trial operation, the noise is greatly reduced, the pressure is stable, and the energy-saving effect is obvious.
Henan Energy Xinyi Mining is only a microcosm of the energy-saving applications in the coal industry. As the energy-saving emission reduction bridgehead inverter industry, frequency converter in the production of coal mines more and more, on the coal mine, underground electrical equipment for energy-saving technological transformation, to improve the level of modernization and automation of coal mining equipment and improve the economic efficiency of enterprises Have a positive effect.
Energy-saving inverter will be a new direction
"At present, the domestic inverter industry is starting from the simple provision of products began to provide users with systematic solutions, from high-end products imported into the rapid rise of domestic brands.In addition to take the high-end line, promotion of energy saving is to promote China's frequency The development of the power industry, frequency conversion technology is in transition from speed to energy saving process. "Inverter company in Shanxi said.
Mine converter used in coal mine system transformation achieved good results and economic benefits by coal companies of all ages. According to reports, through the use of inverter, coal mine fan and other equipment can save more than 30%.
China's mining market is an important area for high-voltage frequency conversion. The mining system emphasizes safety. However, the development model formed by China's mining system over the years is not ideal in terms of resource utilization efficiency and other aspects. As a result, there is much room for technological upgrading and equipment upgrading.
Henan Energy Xinyi Mining official told reporters that the emulsion pump station motor is running at full speed, the emulsion system can not be fully utilized, this will result in a waste of energy, energy-saving inverter is essential. The motor of emulsion pump station runs at full speed for a long time, which increases mechanical wear and shortens the service life of the machine. After using frequency conversion control, the coal enterprise realizes adjusting the motor speed according to the system fluid volume and minimizing the power consumption Unnecessary loss, so coal enterprises to carry out technological transformation of energy-saving is imperative.
"Coal mine equipment such as elevators, belt conveyors and other use of inverter technology is the one hand, the soft start equipment can be extended to extend the life of the equipment; the other hand, can improve efficiency, reduce energy consumption and achieve energy-saving purposes, Can be described as double benefit. "He Kang frequency technology (Wuhan) Co., Ltd. Chen Yu, deputy general manager, said the inverter is based on the needs of the motor control appear, but in the process of using and found that it has significant energy savings. "At present, only some of the major mines in the country have been retrofitted with frequency converters, and most of them have only installed frequency converters on their main equipment. From this perspective, the market is still in a vacancy," he said.
An industry expert focused on the inverter market said that the mine conversion system is in many cases an indispensable device for coal production and will not be too affected by the economic environment and customer short-term affordability. Frequency of leading domestic enterprises have superior value for money products, can replace some of the high-end foreign products. With the pressure on the cost of coal enterprises, the possibility of purchasing domestic products will be even higher.
Reporter learned in the interview, inverter as a weapon of energy-saving emission reduction has become a thermal power plant "standard."
According to the statistical results, most of the electricity consumed by the power plants are fans and pumps, and the use of high-voltage frequency converters can save 30% of such loads on average, and even some power plants have achieved a high level of energy saving of 40% to 50%. According to energy-saving 30% of the calculation, about 3 years to recover the cost, and a high-voltage inverter life expectancy of 20 years or more, in the next ten years, you can imagine the benefits. Experts believe that high-voltage frequency control system will become the primary product of industrial energy-saving promotion.
