1 and the characteristics of Delixi frequency converter;
Delixi frequency converter is mainly used in fans, pumps and compressors in electric power, petrochemical, metallurgical, water conservancy and other industries, especially in high-voltage and high-power fans and pump machinery, replacing the traditional air deflector and throttle valve, which can control the air volume and flow in time according to the load and significantly improve the energy-saving effect. In addition, it can improve and adapt to the operating environment, smooth acceleration and deceleration, improve processing technology and other functions.
After adopting frequency conversion speed regulation, the energy-saving effect of fans and pumps is the most obvious, and the energy-saving rate can reach 20% ~ 60%. This is because the power consumption of fans and pumps is directly proportional to the cubic power of rotation speed. When the average flow required by users is small, the rotating speed of fans and pumps is low, and its energy-saving effect is also very impressive. However, when the traditional baffle and method are used for flow regulation, the power consumption changes little. Because there are many such loads, accounting for about 20% ~ 30% of the total capacity of AC motors, it is of great significance to save energy. For some constant torque loads running at low speed, such as conveyor belt, variable frequency speed regulation can also save energy. In addition, for large energy consumption (such as wound motor) and complex and inefficient (such as gantry planer), the energy-saving effect is also obvious.
