The maintenance and inspection of Shandong CNC welding equipment can be carried out by visual method. According to the external performance of the electrical component failure, the method of judging the failure can be checked by means of seeing, smelling and listening. Here are the relevant steps:
① Investigation: ask the operator and the personnel present at the time of the fault, including the external performance of the fault, the approximate location and the environmental conditions at the time of the fault. For example, whether there is abnormal operation, whether the open fire, heat source, etc. are close to the electrical components, whether there is corrosive gas invasion, whether there is water leakage, whether someone has repaired, and the repair content.
② Preliminary inspection: according to the investigation, check whether the external parts of relevant electrical components are damaged, whether the wiring is open or loose, whether the insulation is burnt, whether the fuse indicator of the spiral fuse is bunched out, whether the electrical components are free of water and oil dirt, and whether the switch position is correct.
③ Test welding: after confirming that there is no possibility of further expansion of the fault and causing personal and equipment accidents through preliminary inspection, power can be turned on. After the welding machine is stable and free of abnormal conditions, further welding test inspection can be carried out. During the normal operation of the welding machine, pay attention to whether there is serious diving, abnormal smell, abnormal sound and other phenomena. Once found, immediately stop and cut off the power supply. Pay attention to check whether the temperature rise of electrical components and the action procedure of electrical components meet the requirements of the schematic diagram of welding equipment, so as to find the fault location.
The inspection, repair and troubleshooting of welding equipment shall be recorded according to relevant requirements. It is convenient to accumulate the experience of inspection, routine maintenance and troubleshooting after the occurrence of similar faults in the future, and also serves as the basis for the performance archives of qualified suppliers' products and the selection of products and production units when they are updated and added in the future.
The above inspection items should be flexibly applied according to the situation, but the safety operation regulations must be observed to prevent personal and equipment injury accidents during the equipment maintenance process, and two people should operate and monitor as much as possible.
