How does HT Jigger Dyeing Machine work
Jan 06, 2022
The motor of the unwinding dyeing machine is in the power generation mode from beginning to end. The general practice is to use brake modules and brake resistors to consume the kinetic energy caused by axial braking in the form of heat.
For machines and equipment that work in power generation mode for long hours and months, such as jiggers, this type of method consumes a lot of electromagnetic energy.
Scientific and technological innovation Liyuan variable frequency speed controller can be easily applied to the public DC bus. We combined the actual situation to connect the PN bus of the two variable frequency speed controllers in parallel immediately, so that the kinetic energy caused by braking during normal operation will return to drag according to the parallel bus. Of the motor.
In order to better consider that in the case of rapid speed reduction, it is possible that both motors are generating electricity. A braking resistor is still connected in parallel to one of the frequency converters. The work is short-term and consumes little energy.
A very large resistance box under the jig dyeing machine control box can now be completely eliminated, which not only saves energy, but also prevents a very large pyrogen, and the stability of the system software has also been improved.
