What are the methods for analyzing and analyzing the faults of machine tool electrical control lines?
Machine tool equipment application is an important part of enterprise production to meet the needs of the current society. However, in the application process of machine tools, there will inevitably be electrical line faults, which will affect the normal use of machine tools. When the machine tool equipment fails, the relevant staff should scientifically analyze the state of the machine's electrical circuit, and deal with the faults through relevant technology, so that the machine tool equipment operation guarantees normal.
Machine tool electrical line status analysis
When applying machine tool equipment in the production process of the enterprise, the machine electrical circuit state should be analyzed when the new machine tool is installed and the machine tool has a fault. The electrical circuit should be analyzed before the machine tool is installed, and the new machine tool line principle is mastered. Diagnosing machine line faults has a very important role and significance, and is the basis for fault diagnosis and maintenance of electrical lines. Therefore, it is very important to master the correct method when analyzing the state of the electrical circuit of the machine tool. The core methods and related steps mainly include the following four points:
First, the electrical schematic of the wake-up should be analyzed, the number of motors in the machine tool should be found from the main circuit, and the relevant control contactors should be determined. In addition, you should also analyze the motor starting method, whether there is reversal and braking, and can pay attention to whether it can be adjusted.
Second, according to the main contact text symbols in the different motor control contactors in the main circuit, the corresponding coils are found in the control circuit.
Third, find out all the series and parallel parallel components in all contactor coil circuits in the control circuit, such as contactors and various relay coils, transfer switches, buttons and contacts, contacts and travel switches, etc. The relationship is analyzed. It should be clear about the first mover and the latter mover, and it should also be clear which situation will move and which will not move. In other words, it is necessary to analyze the relationship between different electrical components in the control circuit and the constraints between them.
Fourth, the relevant protection devices in the machine tool circuit, as well as the lighting and signal circuits should be analyzed. It should be known about its functioning, and at the same time, the relevant components that can act on the line should be known.
