Electric drive and control unit
Whenever a production process is described, an always important part is always ignored or taken for granted. Early extrusion coating, a composite operation,
Installation of electrical drives and controls is approximately 7%-8% of the line price. At present, electric drive and other devices account for 20%-25% of the production line price.
The programming logic controller (PLC) plays an important role in the hypothetical responsiveness of the mechanical component operating logic. PLC has reduced the number of wires between electrical components and provides diagnostic and correction components and/or production line blocks. A great tool for faults in operation.
Current electric drives can be used with DC drives, variable frequency drives, DC and variable frequency combined drives, computer or digitally operated electric drives, all of which have a beneficial effect on the processing unit.
The control room containing the following electrical components in an air-conditioned room has proven to be cost-effective during the installation of a modern extrusion coating line and has also proven to be beneficial in troubleshooting faults in the production line:
(1) transmission gear and its auxiliary device;
(2) main conversion gear;
(3) Motor Control Center;
(4) programming logic controller;
(5) a separate transformer;
(6) Test instrument;
(7) Various driving devices for other auxiliary equipment.
The controlled transmission and control room facilitate installation and troubleshooting.
