In short, the first step of twisting machine maintenance is to identify the real cause and location of the fault as soon as possible according to the fault phenomenon. These fault handling methods are not strictly limited in practice, and sometimes only one method can be used to eliminate the fault, or multiple methods may be needed at the same time. Its effect mainly depends on the experience of the maintenance technician and the depth of his understanding and mastery of the system principle and structure. This is the quality that maintenance personnel must possess, but at the same time, it puts forward high requirements for maintenance personnel. It requires maintenance personnel in numerical control winding machine to be familiar with the structure and design idea of winding machine and the performance of numerical control winding machine. Only in this way can we quickly find out the cause of the fault and judge the location of the fault. In addition, in order to conduct on-site mapping of some circuits and parts during maintenance, as a senior maintenance personnel, we should also have the ability to draw engineering drawings.
For example, the adjustment of the tension of the winding machine, the screen voltage, the starting position of the winding frame and other adjustable components is a simple but effective method in maintenance. By adjusting the adjustable parts, some innocuous faults can be corrected. For example, if a winding machine that has been used for many years is maintained in an enterprise, its system display screen is dim, and it is normal after adjusting the screen power supply voltage.
Spare parts replacement method
In the maintenance of winding machine, the parts suspected of failure are replaced by intact spare parts. After the maintenance personnel basically judge the cause of the failure, this method can be used to quickly diagnose the fault range, and the winding machine can be quickly put into normal operation, and then the broken parts can be returned for repair. This is the commonly used troubleshooting method in Z at present.
Improve environmental quality law
For some very strange faults, even if the reason can't be found by the elimination and replacement method, it is often necessary to start with the surrounding environment, which is generally divided into two types: power supply and space. To improve the power supply, the stabilized and isolated power supply can be used to improve the fluctuation from the power supply. For some high-frequency interference from the power supply, the capacitor filtering method can be used. Through these preventive measures, it is also necessary to increase and check whether the grounding is good. There are many reasons for space interference, such as dust, gas, foundation vain, vibration, space radiation interference, and so on. Experienced maintenance technicians and professional equipment are needed for inspection and maintenance.
