维修时应详细观察焊接设备本身

来源:http://www.wooferclub.com/  发布时间:2022-07-28 浏览次数:

焊接设备的触点在闭合、分断电路或导线线头松动时会产生火花,因此可以根据火花的有无、大小等现象来检查焊接设备故障。下面来看看详细内容吧。
The contact of welding equipment will produce sparks when the circuit is closed, broken or the wire head is loose. Therefore, the fault of welding equipment can be checked according to the existence and size of sparks. Let's take a look at the details.
控制电动机的接触器主触点两相有火花、有一相没火花时,表明无火花的那相触点接触不良或电路断路;三相中两相的火花比正常大,另外一相比正常小,可初步判断电动机相间短路或接地;三相火花都比正常大,可能是电动机过载或机械部分卡住。
When two phases of the main contact of the contactor of the control motor have sparks and one phase has no sparks, it indicates that the phase without sparks has poor contact or the circuit is open; The spark of two phases in three phases is larger than normal, and the spark of the other phase is smaller than normal, so it can be preliminarily judged that the motor is short circuited or grounded between phases; The three-phase sparks are larger than normal, which may be caused by motor overload or mechanical part seizure.
在控制电路中,电路通电后,检查焊接设备的面板指示灯或者检查输出信号,要分清是可能的故障原因。
In the control circuit, after the circuit is powered on, check the panel indicator light of the welding equipment or check the output signal to distinguish the possible cause of the fault.
正常后,可按一下启动按钮,如按钮??サ惚蘸衔恢枚峡庇星嵛⒌幕鸹?,说明电路通路,故障在接触器的机械部分;如触点间无火花,说明是断路。
After it is normal, press the start button once. If there is a slight spark when the normally open contact of the button is disconnected, it indicates that the circuit path and the fault is in the mechanical part of the contactor; If there is no spark between the contacts, it indicates an open circuit.
电气的动作程序应符合焊接设备说明书和图样的要求。如某一电路上的焊接设备动作过早、过晚或没有动作,就说明该电路或焊接设备有故障。
The electrical action procedure shall comply with the requirements of the welding equipment instructions and drawings. If the welding equipment on a circuit acts too early, too late or does not act, it indicates that the circuit or welding equipment is faulty.

另外,山东数控焊接设备厂家认为还可以根据焊接设备发出的声音、温度、压力及气味等分析判断故障。运用直观法,不但可以确定简单的故障,还可以把较复杂的故障缩小到较小的范围。
In addition, Shandong CNC welding equipment manufacturers believe that the fault can also be analyzed and judged according to the sound, temperature, pressure and smell of the welding equipment. Using the intuitive method, not only the simple faults can be determined, but also the more complex faults can be reduced to a smaller range.
电压测量法是根据焊接设备的供电方式和控制电路板的工作性能,测量各的电压值与电流值并与正常值比较。具体可分为分区块测量法、分段测量法和点测法,判断故障的部位和原因。
The voltage measurement method is to measure the voltage value and current value of each according to the power supply mode of the welding equipment and the working performance of the control circuit board, and compare them with the normal value. Specifically, it can be divided into partition block measurement method, subsection measurement method and point measurement method to judge the location and cause of the fault.
此外如果设备超额不使用,应定期进行运行检查和零部件检查,保证完整。以上就是维修时应详细观察焊接设备本身问题的解答了,如果您有需求选购就来咨询我们http://www.wooferclub.com吧。
In addition, if the equipment is not used in excess, regular operation inspection and parts inspection should be carried out to ensure its integrity. The above is the answer to the problem of observing the welding equipment in detail during maintenance. If you need to purchase, please consult us http://www.wooferclub.com OK.
