Maintenance personnel are divided into maintenance personnel and mechanical maintenance personnel. When the regular sanitary napkin machine breaks down, it is often impossible to distinguish between the responsibilities of electrical maintenance personnel and mechanical maintenance personnel. Fully understand the electromechanical connection of the equipment, understand the action principle, improve the work efficiency and ensure the maintenance quality. The following are common electrical troubleshooting methods of regular sanitary napkin equipment.
In case of electrical failure of regular sanitary napkin machine, do not repair blindly and casually. Before maintenance, judge the fault position according to the fault phenomenon, understand the operation before and after the fault and the abnormal phenomenon after the fault through asking, looking, listening and touching, and accurately eliminate the fault. Q: ask the operator about the operation of the circuit equipment before and after the fault and the symptoms after the fault, and whether the fault is frequent or occasional; Whether there are signs of noise, smoke, sparks, abnormal vibration, etc; Excessive cutting force, frequent start, stop, braking, etc.; Whether there is maintenance, maintenance or line change, etc. Check: check whether there are obvious appearance signs before the fault, such as various signals; Indicating device fuse; Protection electrical buckle action; Wiring falling off; Contact singeing or welding; The coil is overheated and burnt out. Listen: on the premise that the line operation does not damage the equipment, you can power on the test run, and carefully listen to whether the sound of motors and other electrical appliances is normal. Touch: after cutting off, touch the motor, transformer, solenoid coil, fuse, etc. as soon as possible to see if there is overheating.
In regular sanitary napkin machine, the action of electrical components is driven by machinery and hydraulic pressure or closely related to them. Therefore, when repairing electrical faults, check, adjust and eliminate the rescue faults of mechanical and hydraulic components, or cooperate with mechanical maintenance personnel.
Before handling the faults of regular sanitary napkin machine, we should fully understand the structure, action principle, adjustment method and connection of electrical equipment of each part. Generally, equipment performance faults can be divided into two categories: one is that the equipment cannot perform the specified action or reach the specified performance index; Second, the equipment has non specified actions or undesirable phenomena. For the former, in principle, analyze the specified actions of the equipment to meet the specified performance indicators, check whether all these conditions are met, and find out the conditions and reasons for non satisfaction. For the latter, analyze the conditions that the fault action needs to meet, and check the conditions that should not be met at this time, so as to find out the cause of the wrong action. In short, we should start from the action principle of the equipment, first find a wide range of faults, and then check step by step, from coarse to fine, until finally find the fault point and eliminate it. Some fault phenomena cannot be handled simply. According to the parts of these phenomena, analyze the causes, test step by step, determine the problems, and power on the test after troubleshooting. Do not act rashly to expand the fault or cause personal and equipment accidents.
In the maintenance of regular sanitary napkin machine, the premise of ensuring rapid and accurate fault treatment is to do a good job in on-site fault diagnosis, comprehensively analyze Electromechanical, and use more basic principles to consider problems. Only through continuous exploration and summary can we improve work efficiency and ensure maintenance quality.
