維修時應詳細觀察焊接設(shè)備本身

焊接設(shè)備的觸點在閉合、分斷電路或?qū)Ь€線頭松動時會產(chǎn)生火花,因此可以根據(jù)火花的有無、大小等現(xiàn)象來檢查焊接設(shè)備故障。下面來看看詳細內(nèi)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.
控制電動機的接觸器主觸點兩相有火花、有一相沒火花時,表明無火花的那相觸點接觸不良或電路斷路;三相中兩相的火花比正常大,另外一相比正常小,可初步判斷電動機相間短路或接地;三相火花都比正常大,可能是電動機過載或機械部分卡住。
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.
在控制電路中,電路通電后,檢查焊接設(shè)備的面板指示燈或者檢查輸出信號,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,可按一下啟動按鈕,如按鈕常開觸點閉合位置斷開時有輕微的火花,說明電路通路,故障在接觸器的機械部分;如觸點間無火花,說明是斷路。
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.
電氣的動作程序應符合焊接設(shè)備說明書和圖樣的要求。如某一電路上的焊接設(shè)備動作過早、過晚或沒有動作,就說明該電路或焊接設(shè)備有故障。
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.
山東數(shù)控焊接設(shè)備
另外,山東數(shù)控焊接設(shè)備廠家認為還可以根據(jù)焊接設(shè)備發(fā)出的聲音、溫度、壓力及氣味等分析判斷故障。運用直觀法,不但可以確定簡單的故障,還可以把較復雜的故障縮小到較小的范圍。
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.
電壓測量法是根據(jù)焊接設(shè)備的供電方式和控制電路板的工作性能,測量各的電壓值與電流值并與正常值比較。具體可分為分區(qū)塊測量法、分段測量法和點測法,判斷故障的部位和原因。
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.
此外如果設(shè)備超額不使用,應定期進行運行檢查和零部件檢查,保證完整。以上就是維修時應詳細觀察焊接設(shè)備本身問題的解答了,如果您有需求選購就來咨詢我們http://niuniury.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://niuniury.com OK.
