Only in this way can the fault cause be quickly identified. , to determine the fault. In addition, in order to test certain circuits and components during maintenance, as a maintenance personnel, it should also have certain measurement skills, and require maintenance personnel of the intermediate frequency quenching and tempering production line to learn and basically master the basic knowledge about the intermediate frequency quenching and tempering production line , such as high power converter. Technology, computer technology, analog and digital circuit technology, automatic control and drag theory, control technology, learn and master the use of various instruments, instruments and tools commonly used in the maintenance of intermediate frequency quenching and tempering production lines .
2) Be good at thinking
The structure of the intermediate frequency quenching and tempering production line is complicated, the connection between the various parts is close, the fault involves a wide range, and in some occasions, the phenomenon reflected by the fault is not necessarily the root cause of the fault. As a maintenance personnel must adjust the fault phenomenon from the intermediate frequency production line , through the analysis of the process of the fault, for all possible causes, from the table and inside, through the nature of the phenomenon, quickly identify the root cause of the fault and eliminate it . Generally speaking, the maintenance personnel of the intermediate frequency quenching and tempering production line should, in a certain sense, be "more brains, be careful", avoid rushing to conclusions, blindly replace components, especially the power modules and printed circuit boards of the intermediate frequency quenching and tempering production line . .
3) Pay attention to the accumulation
The maintenance speed of the intermediate frequency quenching and tempering production line depends to a large extent on the quality of the maintenance personnel and the accumulation of experience. The more problems the maintenance personnel have encountered and the more faults they have solved, the richer their maintenance experience. Although the MF quenching and tempering production line has various types and different performances, its basic working process and principle are the same. Therefore, after the maintenance personnel have solved a certain fault, the maintenance process and the treatment method should be summarized and summarized in time, and a written record should be formed for reference in the future maintenance of similar faults. Especially for problems that are difficult to solve for a while, and ultimately solved by peer technicians or experts, especially should be carefully observed and carefully recorded to facilitate improvement. Such accumulation of time, in order to achieve the purpose of improving their own level and quality, in the continuous practice of practical maintenance to improve analytical skills and fault diagnosis skills.
4) Good at learning
The maintenance personnel of the intermediate frequency quenching and tempering production line should undergo good technical training and continue to learn the basic theoretical knowledge of electrical and power electronic technology, especially the technical training for specific medium frequency quenching and tempering production lines . The first is to participate in the relevant training courses and the actual training of the installation site of the intermediate frequency quenching and tempering production line , and then learn from the experienced maintenance personnel, more importantly, the self-study for a long time. As the maintenance personnel of the intermediate frequency quenching and tempering production line , not only must pay attention to analysis and accumulation, You should also study hard and be good at thinking. The contents of the IF quenching and tempering production line manual are often numerous, including operation, connection, installation and commissioning, maintenance manual, and function description. These manual materials should be comprehensive and systematically studied during actual maintenance. Therefore, as a maintenance personnel, we must understand the structure of the intermediate frequency quenching and tempering production line system, and in accordance with the actual needs, combined with the maintenance information to guide the maintenance work.
5) Have a professional foreign language foundation
Although the number of domestic production of intermediate frequency quenching and tempering production lines has increased, the key components of the intermediate frequency quenching and tempering production line mainly rely on imports. The supporting manuals and materials often use the original texts, and the alarm texts of the intermediate frequency quenching and tempering production lines are also mostly outside. . In order to quickly confirm the cause of the fault according to the information provided in the system and the information provided in the instructions of the intermediate frequency quenching and tempering production line , as a maintenance personnel, it is best to have a certain professional foreign language reading ability, improve the foreign language level, in order to analyze and deal with the problem. .
6) Skilled in operating intermediate frequency quenching and tempering production lines and using maintenance instruments
The maintenance of the intermediate frequency quenching and tempering production line is inseparable from the actual operation. Especially in the maintenance process, the maintenance personnel usually have to carry out special operation modes that the operator of the general intermediate frequency quenching and tempering production line cannot carry out, for example, setting the parameters of the intermediate frequency quenching and tempering production line and Adjustment, through computer and software online debugging, using the medium frequency quenching and tempering production line self-diagnosis technology. Therefore, in a sense, a high level of maintenance personnel, the level of operation of the intermediate frequency quenching and tempering production line should be higher and stronger than the average operator.
7) Strong hands-on ability
Hands-on ability is the quality that must be possessed by the maintenance personnel of the intermediate frequency quenching and tempering production line . However, high-tech equipment such as the maintenance of the intermediate frequency quenching and tempering production line must have clear purpose, complete ideas and meticulous operation before starting. Before you start, you should carefully think about it, observe it, and find the right hand. It is necessary to make a record during the hands-on process, especially for the installation position of the electrical components, the wire number, the intermediate frequency quenching production line parameters, the adjustment value, etc. In order to recover. After the repair is completed, the “closing” work should be done. For example, the shield shell and fasteners in the intermediate frequency quenching and tempering production line should be installed in place; the wires and cables should be neatly arranged.
When repairing the intermediate frequency quenching and tempering production line , special attention should be paid to the fact that some of the circuit boards in the intermediate frequency quenching and tempering production line need to maintain the parameters of the battery. For these boards, avoid plugging and unplugging them; or not, without knowing the role of the components, Feel free to change the components in the intermediate frequency quenching and tempering production line , set the terminals, adjust the position of the potentiometer arbitrarily, and change the setting parameters arbitrarily to avoid more serious consequences. To do a good job of repairing, we must master the scientific methods, and the scientific methods need to be summarized and improved in the long-term study and practice.
