Because vector control inverter itself has good product performance, no vector inverter used in extrusion equipment, has high
quality operation characteristics.
1. Fast processor to provide higher frequency response, no vector inverter built-in processor, to provide high control precision. Fast
response frequency and good dynamic performance. The process requirements of FEP tube extruder are mainly to control the
constant pressure at the outlet. When the equipment starts to work, the speed is controlled. When the demand pressure is reached,
the pressure control should be switched. There should be no impact in the switching process, which requires the high control
precision of the inverter to correspond to the pressure signal.
2. Vector control shows high torque output at low frequency. The main drive motor of the extruder drives the screw to rotate after
decelerating according to the parallel shaft helical gear reducer. Before the application of V/f control inverter, because we should
take into account the starting torque of the load, to set the relative torque lifting position, if the torque lifting position is too high,
the excitation will be too large in the low frequency light load, easy to cause the motor more serious heating, harm the smooth
operation of the machine equipment. The selection of vector control type vectorless converter can not only ensure the motor's
excellent output characteristics at low frequency, the automatic energy-saving operation of vectorless converter will be accompanied
by the change of torque and reduce the output of the current, not only can save power, but also can clear the probability generated
in the work.
3. Speed control precision up to 5 ‰, torque limit and deflection compensation.
Other applications of frequency converter in FEP tube extruder will be discussed by Dan Kai. For more information about FEP tube
extruder, please continue to pay attention to Shenzhen Dankai Technology Co., LTD.
