How Does A Frequency Converter Reduce The Speed Of A Press?

When the sugarcane layer is too thin, the press speed can be reduced by step frequency converter 60hz to 50hz single phase, using the motor current or nuclear scale output as a feedback signal. frequency converter 50hz to 60hz single phase When a decrease in current or a decrease in metering signal is detected, the motor speed is reduced by a preset ratio, the residence time of the press seam is extended, the bagasse is further pressed and the discharge amplitude is reduced. Combined with the Hall sensor, constant current closed-loop control is realized, so that the current fluctuation is kept within a narrow range, thereby maintaining the uniform thickness of the cane layer being pressed and reducing the fluctuation of the extraction rate caused by unstable feeding.
