Review of motor system energy saving technology and its development
The application of the motor is more common in modern society. However, the motor and its system is in the process of using, the electric energy waste phenomenon because of its energy saving system is not perfect and. A waste of electricity not only reduces the efficiency of energy utilization, but also greatly reduces the overall economic benefits of industry of our country. Then, in view of this phenomenon, this article will carry on the development of motor energy saving technology and system of comprehensive analysis and research.
A brief analysis of energy saving technology, machine and its system
(a) analysis of the motor. The motor is an indispensable equipment of our country industry, its working principle is: in accordance with the law of electromagnetic induction in physics to realize the conversion of electrical energy. It is the role of using electricity to produce torque, and for all kinds of machinery and equipment to provide power source.
The motor has been widely applied in various industries in China are: (1) precision machining of various materials. (2) the rapid transmission of logistics. (3) the operation flow of objects.
(two) analysis of the current situation of energy-saving motor and its system. In terms of the current situation of China's power industry, the situation is very serious, for example: in 2013, China's overall industrial electricity consumption reached 3/5 of the total generating capacity. In such a huge power consumption, there is a large part of the motor itself because of the power loss and wasted. The waste of electric energy, not only let China into a power poor plight of China caused huge economic losses. So, in order to avoid the occurrence of these phenomena, it is necessary to improve the existing energy-saving technology and motor system, in order to make the motor in the operation process, can reduce the power loss.
(three) analysis of energy saving technology of motor and system in our country at present. The motor system energy saving project and its main contents are the following five aspects: (1) with high technology, some more machinery and equipment also will be derived from the energy saving effect. So, the enterprise should before efficiency relatively low mechanical equipment removed, then change into some new and efficient machinery and equipment. (2) to improve the operation efficiency of the whole machine and its system. (3) to change the operation mode of mechanical equipment itself. (4) the overall operation of motor is improved and its system, and real-time monitoring of them. (5) in the process of the transformation of the machine and its system, to strengthen the reform of the oil industry, electromechanical industry, power industry and coal industry.
In general, energy-saving projects to establish a perfect and electromechanical system, the whole industry is to be of great advantage. Because it can not only effectively improve the current situation of China's industrial waste of energy, but also can further improve the overall level of development of industry of our country.
Two to explore the development of motor and system energy saving technology
(a) the development of energy saving technology of frequency conversion. Motor speed driving device can be divided into two types: DC and AC. At present, most energy-saving technology widely used in AC variable speed motor of variable speed control technology. There are four advantages of this energy saving technology. They are: (1) for adjustable speed motor drive device can keep in a relatively stable operating state (2) for motor speed control device can be driven without the operation process of the speed regulating pole (3) to improve the motor and its system start-up capacity (4) can greatly reduce the motor and system startup current. It is because of energy saving technology has these advantages, so it has a significant effect in energy saving motor and its system. Frequency control technology is the common single to control of the speed, it can not afford any system for the motor and energy saving effect. Then, the application of energy saving technology to the motor and frequency control system, is a way to improve motor and electric energy waste of system.
(two) the "empty step-down energy-saving technology. In the whole process of motor operation, most of the time the motor did not achieve full load operation, but the voltage has always been in a high state. In this way, not only will make the whole system in the state of overload, more power will be wasted. So, in order to improve this phenomenon, it will be necessary to "empty the buck" Application of energy saving technology in motor system and to.
The principle of energy saving technology is no-load step-down ": when the motor light load or no-load, adjust the voltage in accordance with the actual operation of the motor. At the same time, the power consumption of stator iron also with voltage changes and make corresponding changes. As a result, it can largely reduce the stator iron from the electric energy loss.
(three) how to make the motor system energy saving technology and achieve further development. Now for the development of the electrical system and its energy-saving analysis, can will promote its further development method is simple examples of: (1) for the motor and the system of all equipment were a comprehensive energy-saving analysis, then for the energy-saving effect is relatively poor equipment to improve the relevant energy-saving technologies. (2) the analysis of the existing motor and energy saving technology system, find out all the factors that affect the energy saving effect, then analyze and process the reasonable of these factors, in order to improve the effectiveness of energy saving technology. (3) the application of new technology will be more effective to the motor system and its high-tech energy-saving technology which, in order to improve the efficiency of the motor and the energy saving purpose.
