With the rapid development of electronic technology, in the AC speed regulation technology, frequency conversion speed regulation technology has become a major development direction of modern electric power transmission. It plays a significant role in saving electricity, reducing maintenance, improving quality and output, and achieving automation. It is widely used in modern industrial production. From the traditional DC motor and slip motor drive to the application of frequency conversion technology, the motor speed regulation method has undergone major changes, and it is necessary to explore the characteristics and effects of inverter drive.

Looking at some domestic and foreign brands of inverters, its characteristics are roughly: you can use standard motor speed control, for other motors are also useful; motor can be high speed and miniaturization; explosion-proof; can be continuous speed; small starting current; Tuning speed is not influenced by current; accelerating and decelerating time can be adjusted; vector control is introduced to achieve fast response and high-precision control and can replace DC motor 1. In view of the application effect of the frequency converter, the main performance is: energy saving; realization of control automation improves the reliability of the equipment; and improves the accuracy of control and equipment performance.

In industrial and mining enterprises, these characteristics of inverters can solve difficult problems for enterprises and also create huge benefits for enterprises. The most typical application of the frequency converter is to use various frequency converters for speed control. In our factory, it is mainly used for speed control of fans and constant torque transmission. A feature of fan pumps is that the load torque is proportional to the square of the speed, and the shaft power is proportional to the cube of the speed. Therefore, the previous motor was operated at a constant speed, and the method of adjusting the air volume with a damper valve was changed to obtain a large amount of power saving effect by adjusting the rotation speed according to the required air volume.

The actual speed control device, the efficiency of different control methods is different. Obviously, the inverter control is closer to the ideal curve and there are more significant energy-saving effects. On the other hand, constant-torque loads such as sinter disk feeders and electronic scale belts can be energy-efficient by using variable frequency speed control. Obviously, a decrease in motor speed will cause the output power of the motor to decrease, and the input power of the inverter, which is proportional to it, will also decrease, that is, the power consumption will be reduced.

Ingredients are an important process in the sintering process. It is to mix the raw materials containing iron, flux, fuel and other raw materials used for sintering in accordance with a certain proportion, and to make the chemical composition of the mixed materials reach the set requirements and maintain Stability, the stability of the ingredients directly affects the quality of the sinter ore and quality. Prior to the use of frequency converter control, raw material ingredients were said to use slip motor control, lower use efficiency, higher energy consumption and complex speed structure, difficult maintenance, poor production environment, high equipment failure rate, large loss, to the production belt Many unfavorable factors come. In view of the problems existing in the original electronic scale, combined with the conditions of the process equipment, the frequency conversion technology and the computer technology are combined, and the pressure sensor is used for real-time monitoring to form a raw material ingredient electronic weighing control system. After the operation effect system of raw materials and electronic scales is put into operation, the reformed batching control system has greatly improved the control accuracy, and is convenient to operate and accurate in actual operation.
