Suppliers of frequency converter supporting equipment remind you that as a developing country, China has relatively scarce resources, and energy conservation is currently the most important development direction for our country. Therefore, variable frequency regulation technology is very important for the development of China and is a key industry supported by China's development. Although the application of variable frequency regulation technology in coal mines is still in its early stages, there are many shortcomings in many areas that cannot fully utilize the role of variable frequency regulation technology. However, frequency conversion regulation technology has broad development space in China's coal mining equipment and will become one of the most important energy-saving technologies in the future. More and more enterprises in China will use frequency conversion energy-saving technology. At the same time, adopting frequency conversion regulation technology in the mechanical equipment of coal mining enterprises is also an important means of developing coal mining enterprises. This can save a lot of operating costs for coal mining enterprises, improve resource utilization, and reduce enterprise expenses. It can also enhance the competitiveness of coal mining enterprises in the market and promote their long-term development.
1、 The problems of energy conservation in coal mining machinery
1. High energy consumption
Although the mechanical equipment of coal mining enterprises can greatly improve the production efficiency of coal, the energy consumed by the operation of mechanical equipment is also a huge figure. With the development of new energy and new technologies, as well as the implementation of green environmental protection, energy conservation and emission reduction activities, coal mining enterprises are facing huge challenges, namely the problem of high energy consumption. The energy consumption of coal mining machinery and equipment is high, which is a very serious problem. Due to the large population and scarce resources in China, energy waste hinders economic development. According to the survey, only about 70% of the electricity consumed by coal machinery equipment during operation is put into production, and the remaining 30% is basically wasted, without playing a substantial role. In addition, with the rapid development of science and technology in China and the use of fully automated technology, the energy consumption of coal mining machinery and equipment will greatly increase, and the amount of wasted energy will gradually increase.
2. Fault energy consumption
In addition to serious energy consumption, coal mining machinery equipment also has a high probability of mechanical failure, which further wastes energy in coal mining enterprises. Coal mining enterprises use a large number of mechanical equipment for production, and the failure rate is also relatively high. Once a failure occurs, it will affect the production efficiency of the enterprise and increase its economic costs. With the rapid development of industrial technology, the demand for coal will greatly increase. The increase in demand for coal mines will bring huge loads to the operation of mechanical production equipment, resulting in prolonged equipment use. This will have an impact on the operation of coal mining machinery and equipment, greatly increasing the probability of equipment failure. In severe cases, it will affect the safety of production personnel and cause irreversible losses.
2、 Variable frequency regulation technology
Variable frequency regulation technology is very popular in China and is applied in many fields. The most common variable frequency air conditioner we use is the variable frequency regulation technology, which can greatly save energy consumption of the air conditioner. Frequency conversion technology is combined with microelectronics technology to form a frequency converter, which adjusts the power supply of mechanical equipment and adjusts the frequency of the air conditioning power supply according to actual needs, thereby fully investing the power supply into production, reducing energy waste, and improving energy utilization efficiency.
1. Frequency conversion simulation
The essence of variable frequency regulation technology is energy saving. By installing variable frequency regulation technology in coal mine machinery and equipment, energy-saving operations can be carried out on the equipment. Frequency conversion mediation technology can be implemented through a computer network platform, where production plans are inputted into the computer's ports, incorporating the user's thoughts to simulate relevant work scenarios. Analyze and study the simulated work content, determine whether it meets relevant standards, and finally make relevant improvements to determine the final operational plan. This frequency conversion simulation system can complete relevant instructions, replacing manual debugging in the past, making the equipment more intelligent and user-friendly. At the same time, this simulation system can greatly improve the efficiency of equipment, reduce energy consumption, and save operating costs.
2. Scientific guidance
Frequency conversion technology is one of the important means of mechanical energy-saving design and renovation in today's society. Through frequency conversion energy-saving technology, a large amount of electricity energy can be saved. Variable frequency regulation technology plays an important role in the power system of coal mine equipment, which can reduce the operational difficulty of the power system and improve work efficiency. The power system structure of coal mining equipment is complex, and the difficulty of operation is also very high. There are huge safety hazards, and improper operation can lead to safety accidents and serious consequences. After adopting frequency conversion regulation technology in the power system of coal mining enterprises, this situation can be changed to a certain extent, reducing the operational difficulty of the power system and improving work efficiency. At the same time, the use of frequency conversion regulation technology can provide scientific guidance and standardized operation for mining operations, providing guarantees for the safety production of coal mines.
3、 Energy saving methods
1. Reduce energy consumption of reactive power
Variable frequency regulation technology is adopted in coal mine machinery equipment to improve the reactive power of the equipment and reduce the energy consumption of reactive power. The reactive power of coal mining machinery equipment needs to be appropriate. Once the reactive power generated by the equipment is too high, it will cause the equipment to heat up and damage the wiring of the equipment. The reactive power of coal mining machinery equipment can also affect the active power of the power system. Once the factor of reactive power decreases, the useful power of the power system will also decrease accordingly. If such a phenomenon occurs, it will increase the reactive energy consumption, thereby affecting the production efficiency of the equipment and increasing the overall energy consumption of the equipment. By using frequency conversion regulation technology, the consumption of reactive power can be reduced to a certain extent through the regulation of the frequency converter, thereby increasing the efficiency of useful power work and providing overall utilization of equipment electrical energy, achieving energy-saving effects.
2. Change the startup mode
Traditional coal mining machinery and equipment use old-fashioned electric motors, which are started before coal mining operations begin. The starting method is usually hard starting, which can have a huge impact on the power system, affecting its normal operation and causing damage to the power system. During the process of starting the electric motor, if the power system requires a large amount of electricity, the motor will be affected by strong currents and vibrations, causing damage to the valves and baffles of the motor, as well as affecting related mechanical equipment. After applying frequency conversion regulation technology in the coal mine power system, the frequency converter will adjust the relevant current according to the actual needs of the motor, gradually increasing it from zero, which will effectively control the starting current of the engine. This starting method can reduce power consumption, improve energy utilization, protect the valves and baffles of the generator, and extend the service life of the equipment.
3. Variable frequency energy-saving
The application of frequency conversion regulation technology in coal mining machinery equipment can achieve energy-saving effects. Because the operating power of coal mining machinery and equipment is constant, when the operating load of the equipment cannot meet the requirements, the consumption of active power will increase, resulting in energy waste. In the past, in order to regulate the energy required for the operation of the electric motor, it was generally necessary to adjust the energy by changing the baffle and valve. During the adjustment process, energy was wasted and a lot of unnecessary energy was lost. Nowadays, many coal mining enterprises adopt variable frequency regulation technology for their mechanical equipment, which can flexibly adjust the required energy and real-time regulate the energy required for the operation of coal mining equipment. According to the operating status of the motor at that time, the corresponding energy can be adjusted to avoid energy waste, thus saving energy and improving energy utilization efficiency.
Most people in our country are aware of coal mining enterprises because they have made tremendous contributions to the development of our country and provided important energy for the development of various industries. As the main force in coal mining production, coal mining machinery has greatly improved the production efficiency of coal mining enterprises and accelerated the pace of industrial development in China. However, the energy consumption of coal mining machinery is very high, wasting a lot of energy and increasing the operating costs of enterprises, which is not conducive to the development of enterprises. Moreover, with fierce market competition, major enterprises are striving to reduce production costs as much as possible to establish a firm foothold in the market and sustain long-term development. Coal mining enterprises are no exception, they also need to save production costs and face the challenges of new energy. Therefore, adopting frequency conversion regulation technology for energy-saving and emission reduction design of mechanical equipment in coal mining enterprises has become an inevitable trend in social development.
