MotorThe control system for energy-saving construction projects is listed as one of my country's twelve or fifty key energy-saving technology projects, and motor energy conservation is a key management area of the country's energy-saving and emission-reduction work.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.Explosion-proof motorsA kind of motor that can be used in flammable and explosive plants and does not generate sparks during operation.Explosion-proof motors are mainly used in coal mines, petroleum and natural gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.With the active implementation of various important measures for energy conservation and emission reduction in our country and the gradual improvement and implementation of the relevant policies of high-efficiency energy-saving motor subsidies, high-efficiency energy-saving motors will lead to rapid development.
Before the policy is implemented, it has been difficult to promote high-efficiency motors. High-efficiency motors are only 10% of China's total motors, mainly low-efficiency motors. Enterprises are not willing, because the use of high-efficiency motors is a cost. I believe that with the motor With the implementation of energy subsidies, the cost of high-efficiency motors will reduce the procurement costs of companies that operate high-efficiency and energy-saving motors. The procurement will drop significantly, and the application of high-efficiency motors will increase.
There are many teaching methods for industrial production enterprises to achieve cost-effective and energy-saving. One of the main ones is to replace the original low-efficiency motor by replacing the high-efficiency energy-saving motor. The use of a high-efficiency motor for a long-term constant load can achieve a better energy-saving design effect.Using a variable frequency motor or installing a frequency converter on the motor, the combination of the two different methods will be more energy-saving.
Frequency conversion energy saving refers to saving electricity by adjusting the motor speed; frequency converter speed adjustment is mainly used in occasions where the load changes, and the energy saving effect is very obvious. Its energy saving principle is simple, and the frequency is changed according to the needs, and then the output power is changed.
