Processing of Fault Diagnosis Program of Control System of aluminum profile extrusion press machine plant line

aluminum profile extrusion press machine plant lines have also undergone large-scale and complex changes in the constantly developing society, which has also increased the difficulty of processing aluminum profile extrusion press machine plant lines when they fail. In order to ensure that aluminum profile extrusion press machine plant lines can work better, To effectively improve work efficiency, it is necessary to remove the fault in time when the aluminum profile extrusion press machine plant line fails. Relevant statistics show that when the aluminum profile extrusion press machine plant line fails at this stage, the time used for fault diagnosis occupies 80% of the entire downtime, and the actual maintenance The time is very short. Therefore, in order to enable the equipment operators to understand the control system of the aluminum extrusion press and solve the fault in time, this paper focuses on the analysis of the fault diagnosis procedure of the control system of the aluminum extrusion press. After a large amount of practical data, it is found that in the event of failure of the aluminum profile extrusion press machine plant line, it will not only affect the smooth production of the product, but even cause personal safety accidents. Therefore, it is necessary to pay attention to the safety and reliability of the operation of the aluminum profile extrusion press machine plant line. The control system is the main control unit for the operation of the aluminum extrusion press. Once the control system fails, it is bound to think of the normal operation of the aluminum extrusion press. Moreover, it is difficult to find the defects in the operation of the aluminum extrusion press due to the failure of the control system. If it is dealt with in time, the failure cannot be contained in time, which will lead to the expansion of the failure and cause serious consequences. The normal operation of the aluminum profile extrusion press machine plant line can only be guaranteed under safe conditions. Therefore, when the aluminum profile extrusion press machine plant line fails, it should first check whether the environment where the aluminum profile extrusion press machine plant line is located is under safe operating conditions. When it is satisfied, the cause of the failure of the aluminum extrusion press equipment can be judged, so as to better realize the processing and maintenance of the equipment. For some relatively simple and easy-to-handle failures of the aluminum extrusion press, for example, the oil temperature in the aluminum extrusion oil tank is too high. High or the oil level of the fuel tank is too high, the equipment maintenance personnel can connect the equipment to the computer, and can directly output the failure program of the aluminum extrusion press. A high signal will send out a continuous, more than 20 s signal, this simple fault diagnosis time is relatively small, the impact on work is relatively small.
