Energy feedback unit suppliers remind you that whether it is a dedicated frequency converter or a vector frequency converter, certain conditions are required in terms of energy saving. Today, we will share with you knowledge on how to speed up and save electricity more effectively.
1. There are certain conditions for a frequency converter to save electricity. By appropriately changing the operating parameters without affecting the use, the energy consumed by unreasonable operating parameters can be saved, and the transition from general operation to economic operation can be achieved.
2. Vector frequency converters must reduce energy consumption, and the greater the decrease, the more energy savings they can achieve. In principle, vector frequency converters cannot save electricity without reducing it.
3. The vector frequency converter is related to the load rate of the motor. When the load rate is between 10% and 90%, the power saving rate is about 8% to 10% higher, and the corresponding power saving rate is higher when the load rate is low. But the reactive power saving rate is about 40% to 50%, which does not include electricity bills.
4. The rationality of the vector frequency converter is related to the parameter values of the original operating conditions. For example, it is related to the adjustable values such as pressure, flow rate, and speed. If the adjustable value is large, the energy-saving rate will be high, otherwise the opposite is true.
5. The vector frequency converter is related to the original adjustment method used. It is not economical to adjust operating parameters using imported or exported valves. If it is changed to vector frequency converter speed regulation, it is economically reasonable. After using a vector frequency converter for speed regulation, it can save up to 20% to 30% more electricity than adjusting the operation method manually with valves.
6. The vector frequency converter is related to the original speed regulation method used. For example, originally using a slip motor for speed regulation, due to its low regulation rate, especially at medium and low speeds, the efficiency was only below 50%, which was not economical. After switching to a vector frequency converter for speed regulation, this part of the electrical energy was saved. At present, most industries such as light industry, textile, papermaking, printing and dyeing, plastics, rubber, etc. still use slip motors. Therefore, using vector frequency converters to achieve energy conservation is an urgent task for technological transformation.
7. The vector frequency converter is related to the working mode of the electric motor. For example, the energy savings of continuous operation, short-term operation, and intermittent operation are different.
8. The vector frequency converter is related to the duration of motor operation. For example, if the device is turned on 24 hours a day, the energy savings will be greater if it is turned on 365 days a year, and vice versa.
