Frequency conversion module refers to the inverter module of the inverter, is a more important part of the inverter, used for weak current (main control board) control of strong current (compressor drive power) frequency conversion control, widely used in all kinds of motors, electrical equipment. Today, Xiaobian will take you to understand what role the frequency conversion module has.

1, frequency conversion energy saving

Frequency conversion energy saving is mainly manifested in the application of fans and pumps. After the fan and pump load is regulated by frequency conversion, the power saving rate is 20% to 60%, which is because the actual power consumption of the fan and pump load is basically proportional to the third square of the speed. When the average flow rate required by the user is small, the fan and pump use frequency control to reduce their speed, and the energy-saving effect is very obvious.

2, in the automation system application

Because the inverter has a 32-bit or 16-bit microprocessor, with a variety of arithmetic logic operations and intelligent control functions, the output frequency accuracy is 0.1%~0.01%, and there is a perfect detection and protection link, so it is widely used in automation systems. For example: the chemical fiber industry in the winding, stretching, metering, wire guide;

Plate glass annealing furnace, glass kiln stirring, edge pulling machine, bottle making machine in glass industry; Electric arc furnace automatic feeding, batching system and elevator intelligent control, etc. Improve the process level and product quality of the application of frequency in CNC machine tool control, automotive production lines, paper and elevator applications.

3, the application of improving the process level and product quality

Inverter can also be widely used in transmission, lifting, extrusion and machine tools and other mechanical equipment control fields, it can improve the process level and product quality, reduce the impact and noise of the equipment, extend the service life of the equipment. After the use of frequency conversion speed control, the mechanical system is simplified, the operation and control are more convenient, and some can even change the original process specifications, thus improving the function of the entire equipment.

4, to achieve the motor soft start

The hard start of the motor will not only cause serious impact on the power grid, but also require too much capacity of the power grid, and the large current and vibration generated during the start of the baffle and valve are greatly damaged, and the service life of the equipment and pipelines is extremely unfavorable.

After using the frequency converter, the soft start function of the frequency converter will make the starting current change from zero, and the maximum value will not exceed the rated current, which reduces the impact on the power grid and the requirements for the power supply capacity, extends the service life of the equipment and valves, and also saves the maintenance cost of the equipment.
