The general manager Shao Mingyuan warmly received Mr Sun and his entourage. Mr Sun led the team to visit the company’s exhibition hall to investigate and understand the development of the enterprise and product sales. At the investigation site of the exhaust gas collection and treatment system, Mr. Shao introduced to Mr Sun the company's work in water paint source replacement and exhaust gas treatment terminal treatment in detail. In the process of investigation and guidance, Mr Sun gave full recognition to Yueqiu's first investment in exhaust gas treatment and its demonstration role together and its adherence to the development concept of green environmental protection. Party secretary of nanxun district party committee Yang Weidong, party secretary of development zone party committee and other leader participated in the investigation.
What are the advantages of variable frequency motors as compared with traditional motors?
More Energy Efficient When the motors of all household appliances are running, harmonic voltages and currents of different degrees are generated, which makes the motors run under non-sinusoidal voltages and currents. High-order harmonics will cause the increase of stator copper loss, rotor copper loss, iron loss and additional loss, the most significant is the rotor copper loss. Because the ordinary AC asynchronous motor rotates at a synchronous speed close to the fundamental frequency, the high-order harmonic voltage cuts the rotor bar with a large slip, which will cause a large rotor loss. In addition, the additional copper loss due to the skin effect needs to be considered. These losses will cause the motor to generate additional heat, reduce efficiency, and reduce output power. However, the energy consumption can be reduced by about 20%-30% if a variable frequency motor is used. Long Lifetime When the motor is running, the carrier frequency is about several thousand to more than ten kilohertz, which makes the stator windings of the motor bear a very high voltage rise rate, which is equivalent to applying a very steep impulse voltage to the motor, so that the inter-turn insulation of the motor bears a more severe test. And the variable frequency motor can work in the rectifier filter under the voltage, which can achieve the much stable performance and longer life. Low Noise /p> The vibration and noise caused by electromagnetic, mechanical, ventilation and other factors of ordinary asynchronous motors become more complicated. The time harmonics in the frequency conversion power supply interfere with the inherent space harmonics in the electromagnetic part of the motor to form various electromagnetic excitation forces. When the frequency of electromagnetic force wave is consistent with or close to the natural vibration frequency of the motor body, the resonance phenomenon will occur and the noise will be increased. Due to the wide working frequency range and wide speed variation range of the motor, the frequency of various electromagnetic waves is difficult to avoid the natural vibration frequency of each component of the motor. But variable frequency motor can effectively solve these problems.
Electrical motor enterprises seize the national strategic opportunities to achieve the industry from large to strong
In our country, the electrical machinery industry has gone through a century of history. At present, my country has become the largest country in the production, use and export of small and medium-sized motors. The domestic possession of small and medium-sized motors has reached 1.6 billion kilowatts. However, my country's high-efficiency and energy-saving motor technology has not yet reached the world's advanced level, and there are still some problems in the promotion of high-efficiency motors. . Therefore, motor companies should seize the historical opportunities of the country’s implementation of major strategies such as "One Belt and One Road", "Industry 4.0", and "Made in China 2025", and take innovation-driven, intelligent transformation, strengthening of the foundation, and green development as the guiding ideology, and work hard and determined. Enterprising, realize the electric machinery industry from big to strong as soon as possible. Electric machinery companies are seizing the national strategic opportunities and realizing that the industry grows from big to strong. At present, our country has become a major producer of motors, but it still faces some problems in the promotion and application of high-efficiency motors. Therefore, the electrical machinery industry should seize development opportunities, and take innovation-driven, intelligent transformation, strengthening of the foundation, and green development as the guiding ideology to realize the early realization of the electrical machinery industry from big to strong. Motors must be used wherever electrical energy is converted into mechanical energy or mechanical energy is converted into electrical energy. Therefore, the motor industry as a whole has a huge market capacity.
Motor energy saving welcomes the golden age, industry competition and opportunities coexist
Various types of motors in my country account for a large proportion of electricity consumption, so the prospects for energy saving of motors are huge. The next ten years will be the golden age of technological energy conservation. Technical energy saving covers a wide range, which can be summarized into three key areas: industrial field, construction field and electromechanical field. Energy saving of motors is a key part of industrial energy saving. Motor energy saving welcomes the golden age In my country, technical energy conservation covers a wide range, including the use of waste heat, energy-saving lighting, energy-saving transportation and electric power, steel, non-ferrous metals, petroleum and petrochemical, chemical, building materials and other key traditional industries such as advanced and applicable technological transformation. Summarized into three key areas: the industrial field, the construction field and the electromechanical field. Energy saving of motors is a key part of industrial energy saving. The power consumption of all kinds of motors in our country accounts for 60%~70% of the total power consumption of my country's industry, so the prospect of motor energy saving is huge. However, the competition in the field of motor energy saving is the most fierce and cruel in many technical energy saving industries. According to the current research, there are many major sub-sectors and listed companies for motor energy conservation, including power station air cooling technology, power plant secondary equipment, carbon capture and storage, frequency converters, energy-saving transformers, high-efficiency motors, electronic power and components, etc. Sub-industries.
