焊接专机出现问题后有哪些方法检查?在这里讲一下对比、置换元器件、逐步开路(或接入)法,展开内容分析一番吧。
What are the methods to check when there is a problem with the welding machine? Here we will talk about the methods of comparison, replacement of components and parts, and gradual open circuit (or access), and carry out the content analysis.
1)对比法
1) Contrast method
把检测数据与图样资料及平时记录的正常参数相比较来判断故障。对于无资料又无平时记录的焊接设备,可查阅相关手册或者产品说明书,也可以与同型号的完好焊接设备相比较。
Compare the test data with the drawing data and the normal parameters recorded at ordinary times to judge the fault. For welding equipment without data or usual records, you can refer to the relevant manuals or product manuals, or compare it with the intact welding equipment of the same model.
电路中的焊接设备元件属于同样用途性质或多个元件共同控制同一设备时,可以利用其他相似的或同一电源的元件动作和数据情况来判断故障。
When the welding equipment components in the circuit belong to the same purpose or multiple components jointly control the same equipment, the action and data of other similar components or components of the same power supply can be used to judge the fault.
2)置转换元件法
2) Set conversion element method
为了保证焊接设备的利用率,某些电路的故障原因不易确定或检查时间过长时,利用相同焊接设备上可转换的同一性能良好的元器件实验,以证实故障是否由此电器在元器件引起。
In order to ensure the utilization rate of welding equipment, when the fault cause of some circuits is difficult to determine or the inspection time is too long, use the same components with good performance that can be converted on the same welding equipment to test to confirm whether the fault is caused by the electrical appliance in the components.
运用转换元件法检查时应注意,当把原焊接设备拆下后,要认真检查是否已经损坏,只有肯定是由于该焊接设备本身因素造成损坏时,才能换上新焊接设备,这样可以防止新换元件再次损坏。
When using the conversion element method to check, it should be noted that when the original welding equipment is removed, it should be carefully checked whether it has been damaged. Only when it is certain that the damage is caused by the welding equipment itself, can the new welding equipment be replaced, so as to prevent the new components from being damaged again.
3)逐步开路(或接入)法
3) Step by step open circuit (or access) method
山东焊接专机设备中多支路并联且控制较复杂的电路短路或接地时,一般有明显的外部表现,如冒烟、有烧焦痕迹等。电焊机内部或带有护罩的电路短路、接地时,除熔断器熔断外,不易发现其他外部现象,这种情况可采用逐步开路(或接入)法检查。
In Shandong special welding machine equipment, when multiple branches are connected in parallel and the circuit with complex control is short circuited or grounded, there are generally obvious external manifestations, such as smoking, burning traces, etc. When the circuit inside the welding machine or with shield is short circuited and grounded, it is not easy to find other external phenomena except the fuse is blown. This situation can be checked by the step-by-step open circuit (or access) method.

①逐步开路法
① Step by step open circuit method
遇到难以检查的短路或接地故障,可重新更换熔断器熔体,把多支路电路,一路路逐步或重点地从电路中断开,然后通电试验,若熔断器一再熔断,故障就在刚刚断开的这条电路上。
In case of short circuit or grounding fault that is difficult to check, the fuse melt can be replaced again, the multi branch circuit can be disconnected from the circuit step by step or emphatically, and then the power on test. If the fuse blows repeatedly, the fault is on the circuit just disconnected.
然后再将这条支路分成几段,逐段地接入电路。当接入某段电路时熔断器又熔断,故障就在这段电路及某焊接设备元件上。这种方法简单,但容易把损坏不严重的焊接设备元件彻底烧毁。
Then the branch is divided into several sections and connected to the circuit section by section. When a certain circuit is connected, the fuse blows again, and the fault lies in this circuit and some welding equipment components. This method is simple, but it is easy to completely burn the components of welding equipment that are not seriously damaged.
②逐步接入法
② Step by step access method
电路出现短路或接地故障时,换上新熔断器逐步或重点地将各支路一步一步地接入电源,重新试验。当接到某段时熔断器又熔断,故障就在刚刚接入的这条电路及其所包该文章讲述了焊接设备故障的检查方法与维修经验.含的焊接设备上。
In case of short circuit or ground fault in the circuit, replace the new fuse, gradually or emphatically connect each branch to the power supply step by step, and retest. When receiving a certain section, the fuse blows again, and the fault lies in the circuit just connected and its package. This article describes the inspection methods and maintenance experience of welding equipment faults, including welding equipment.
在排除焊接设备故障时,可用一根绝缘棒将有关继焊接设备、接触器以及电磁铁等用外力强行按下,使其??サ惚蘸?,然后观察焊接设备部分或机械部分出现的各种现象,如电动机从不转到转动,设备相应的部分从不动到正常运行等。更多相关内容就来我们网站http://www.goandcatch.com咨询吧。
When troubleshooting the welding equipment, an insulating rod can be used to forcibly press the relevant relay welding equipment, contactors and electromagnets with external force to close their normally open contacts, and then observe various phenomena in the welding equipment or mechanical part, such as the motor never turns to rotate, and the corresponding part of the equipment never moves to normal operation, etc. Come to our website for more relevant content http://www.goandcatch.com Consult.
