Since its development, frequency conversion technology has achieved significant energy savings in many production processes. When selecting the inverter speed control or energy saving, what principles should be followed, as a prerequisite for the decision program. If the local electricity price is high, the economic benefits will be even greater at the same power savings. This is an inevitable consideration.
The ten major principles of energy-conservation frequency changer selection 1) are related to the importance of this unit's production process. First of all, it is necessary to select products with high power consumption, high product cost, and current use of speed control methods that are not economical and reasonable. Each of them should be reconstructed. Switching to frequency converters will have the effect of achieving immediate results and doing more with less.
2) Related to the original adjustment method used. The use of imported or exported valves to adjust the operating parameters is not economical. If it is changed to speed control, it is economically reasonable. After the inverter is used to adjust the speed, the operation method can be adjusted by more than 20% to 30%.
3) There are certain conditions for the inverter to save electricity. Under the conditions that do not affect the use, after properly changing the parameters of operating conditions, the energy consumed by the irrational operating parameters can be saved, and it can be converted from general operation to economic operation.
4) If you want to save energy, you must reduce the frequency. The larger the decrease, the more energy you save. Without reducing the frequency, the inverter cannot, in principle, save power.
5) It is related to the reasonableness of the original operating condition parameter values. For example, the pressure, flow rate, speed, etc., are related to the magnitude of the adjustable amount. If the amount of adjustment is large, the energy saving rate is high, otherwise it is the opposite.
6) Related to the motor load rate. When the load rate is between 10% and 90%, the energy saving rate is at most about 8% to 10%. The low load rate corresponds to a higher power saving rate. However, the rate of reactive energy saving is about 40% to 50%, which is excluding electricity charges.
7) It depends on the length of time the motor is started. For example, if you turn on the phone for 24 hours a day, the power saving will be large for 365 days a year, and vice versa.
8) It depends on the working mode of the motor. For example, the power consumption of continuous operation, short-time operation, and intermittent operation is different.
9) It depends on the power of the motor itself. At the same power saving rate, the large power saving value is large, and the economic benefit is large. Even if the power saving rate is lower than that of the low power motor, the actual profit is large.
10) It is related to the original speed control method. For example, the original slip motor speed, due to low speed efficiency, especially in the middle and low speed, the efficiency is only 50% or less, very economic, after the inverter speed control, this part of the power saved. At present, most of the industries such as light industry, textiles, papermaking, printing and dyeing, plastics, and rubber still use slip motors. Therefore, the use of frequency converters to achieve energy saving and technological transformation work are urgent tasks.
