山东数控焊接设备的维修检查可以使用直观法检查，根据电器元件故障的外部表现，通过看、闻、听等手段检查判断故障的方法。下面来讲讲其相关步骤：

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调查情况：向操作者和故障发生时的在场人员询问情况，包括故障外部表现、大致部位以及发生故障时的环境情况。如有无异常操作、明火、热源等是否靠近电器元器件、有无腐蚀性气体侵入、有无漏水、是否有人修理过以及修理的内容等。

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初步检查：根据调查的情况，查看有关电器元器件外部有无损坏、连线有无断路、松动，绝缘有无烧焦，螺旋熔断器的熔断指示器是束跳出，电器元器件有无进水和油垢，开关位置是否正确等。

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试焊：通过初步检查，确认没有可能使故障进一步扩大和造成人身、设备事故后，可以通电。稳定无异常情况后，可进一步做焊接试验检查，焊机在正常工作中要注意有无严重跳水、异常气味和异常声音等现象，一经发现应立即停止，切断电源。注意检查电器元器件的温升及电器元器件的动作程序是否符合焊接设备原理图的要求，从而发现故障部位。

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.

对焊接设备故障的检查和维修排除，要按照相关要求做好记录。方便以后类似故障发生后的检查、日常维护保养和故障排除的经验积累，也为以后更新、添置时作为合格供应方产品的业绩档案和选择产品和生产单位的依据。

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.

以上一些检查事项，要视情况灵活运用，但必须遵守操作规章，防止在设备维修过程中出现人身、设备伤害事故，并且尽可能两人操作和监护。更多相关内容就来我们网站http://www.tayfsk.com咨询吧！
