Maintenance and troubleshooting of bus bar processing machine
There may be some faults in the process of bus processing. The analysis process of the electrical fault of the bus machine is the troubleshooting process. Therefore, some common troubleshooting methods for the electrical fault of the bus machine. Let's take you to understand: 1. Power supply: The power supply is The energy source for the maintenance system and even the entire machine tool to work normally. Its failure or failure will lose data and cause downtime. In the worst case, it will destroy part or all of the system. Western countries have sufficient power and high quality power grids, so the power supply of their electrical systems There are fewer design considerations, which is slightly insufficient for China's power supply network with large fluctuations and higher harmonics. Coupled with some man-made factors, it is inevitable that there will be failures caused by the power supply. Two, CNC system Position loop failure 1. Position loop alarm. It may be that the position measurement loop is open; the measuring element is damaged; the interface signal established by the position control does not exist, etc. 2. The coordinate axis moves without instructions. It may be excessive drift; position The loop or speed loop is connected as positive feedback; the feedback wiring is open; the measuring element is damaged. Three, the machine coordinate can not find the zero point. It may be that the zero direction is far away from the zero point; the encoder is damaged or the wiring is open; the grating zero mark is shifted; the zero return deceleration switch Failure. Fourth, the dynamic characteristics of the machine tool deteriorates, the quality of the workpiece processing is reduced, and the machine tool even vibrates at a certain speed. One of the larger ones may be the excessive clearance of the mechanical transmission system or even serious wear or insufficient lubrication of the guide rails or even wear. For the electrical control system, it may be that the speed loop, position loop and related parameters are no longer in the best matching state, and the optimization adjustment should be re-optimized after the mechanical failure is basically eliminated. Five, occasional shutdown failure. There are two One possible situation: One situation is that the problem in the related software design as mentioned above causes the shutdown failure under certain specific operation and function operation combinations. Under normal circumstances, the machine tool will disappear after the power is turned on again; other One situation is caused by environmental conditions, such as strong interference (power grid or peripheral equipment), excessive temperature, excessive humidity, etc. Such environmental factors are often ignored by people, such as placing machine tools in ordinary factories or even close to them in the southern region Near the open door, the electric cabinet is running for a long time, and there are a lot of equipment that produces dust, metal chips or water mist nearby. The above is about the maintenance and troubleshooting of the bus processing machine. I hope to help you, our company It is the business of bus processing machines. If necessary, please consult us.
