At present, there are many kinds of domestic electromechanical products, but in general, the system efficiency is relatively low, and it is in an inefficient operation for a long time. Some enterprises that produce electromechanical systems lack understanding of the economic benefits brought by electromechanical systems, or have obstacles to the technical problems of electromechanical energy-saving retrofits. The industry believes that although energy-saving electromechanical equipment has been in a state of coldness and heat for a long time, under the promotion of low-carbon, energy-saving and emission-reduction policies, the promotion and application of energy-saving electromechanical equipment will surely make substantial progress.
1. The purpose of using frequency conversion; constant voltage control or constant current control.
2, the load type of the inverter; such as the vane pump or the volume pump, pay special attention to the performance curve of the load, the performance curve determines the way of application.
3. The matching problem between the inverter and the load;
The frequency converter allows the motor drive system to achieve two wishes. One is to make the motor achieve higher efficiency operation; the other is to make the motor controllable, which also avoids manpower. But the problem before the engineer is: There are so many types of motor loads, and the performance requirements of the equipped inverters are very different. How to choose the right inverter for the motor?
