1.先問(wèn)后動(dòng)
1. ask first and then move
對(duì)于有故障的焊接設(shè)備,如果不知道真相,不要急于動(dòng)手,要了解設(shè)備的性能,并詢問(wèn)操作人員故障是如何發(fā)生的,故障現(xiàn)象是怎樣的。對(duì)于不熟悉、復(fù)雜的焊接設(shè)備,應(yīng)先熟悉設(shè)備的電路原理和結(jié)構(gòu)特點(diǎn),并遵守相應(yīng)的規(guī)定。拆卸前,應(yīng)充分熟悉各部件的功能、位置、連接方式及與周圍其他部件的關(guān)系。如果沒(méi)有焊接設(shè)備的電路圖和裝配圖,應(yīng)同時(shí)進(jìn)行拆卸、草圖和標(biāo)記,并對(duì)拆卸的物體進(jìn)行標(biāo)記,并注意。
For faulty welding equipment, if you don't know the truth, don't rush to start. You should understand the performance of the equipment and ask the operator how the fault occurs and what the fault phenomenon is. For unfamiliar and complex welding equipment, first be familiar with the circuit principle and structural characteristics of the equipment, and comply with the corresponding regulations. Before disassembly, be fully familiar with the function, position, connection mode of each component and the relationship with other surrounding components. If there is no circuit diagram and assembly drawing of welding equipment, disassembly, sketch and marking shall be carried out at the same time, and the disassembled objects shall be marked, and attention shall be paid to safety.
2.先外后里
2. from outside to inside
一般應(yīng)檢查焊接設(shè)備外部是否有明顯的損傷跡象,電焊機(jī)的零部件是否損壞,并了解其維修歷史、使用壽命,觀察使用現(xiàn)場(chǎng)的環(huán)境和使用情況。焊接工藝等,然后檢查電焊機(jī)。拆卸前應(yīng)排除周邊故障因素,如接線、接地、配電容量、所用焊接工藝是否正確等。只有確定是電焊機(jī)內(nèi)部故障后,才能進(jìn)行拆卸。否則,盲目拆卸可能會(huì)使焊接設(shè)備越來(lái)越差。如電極弧焊、埋弧焊、鎢極氣體保護(hù)焊、等離子弧焊和熔融氣體保護(hù)焊機(jī)。
Generally, check whether there are obvious signs of damage on the outside of the welding equipment, whether the parts of the electric welding machine are damaged, understand its maintenance history and service life, and observe the environment and service conditions on the use site. Welding process, etc., and then check the electric welding machine. Before disassembly, eliminate surrounding fault factors, such as wiring, grounding, power distribution capacity, whether the welding process used is correct, etc. Only after the internal fault of the electric welding machine is confirmed, can it be removed. Otherwise, blind disassembly may make the welding equipment worse and worse. Such as electrode arc welding, submerged arc welding, tungsten gas shielded welding, plasma arc welding and molten gas shielded welding.
3.先機(jī)后電
3. machine before electricity
檢查配套焊機(jī)焊接設(shè)備的機(jī)械零部件、潤(rùn)滑、氣路、水路、油路系統(tǒng)是否有問(wèn)題。只有在確定這些系統(tǒng)無(wú)故障后,才能進(jìn)行電氣檢查。檢查電路故障時(shí),應(yīng)使用檢測(cè)儀器找出故障部位,確認(rèn)無(wú)接觸不良故障后,有針對(duì)性地檢查電路與機(jī)器的運(yùn)行關(guān)系,避免誤判,如點(diǎn)焊、縫焊、凸焊及配套焊等設(shè)備。
Check whether there is any problem in the mechanical parts, lubrication, air circuit, water circuit and oil circuit system of the supporting welding machine and welding equipment. The electrical check can only be carried out after it is confirmed that these systems are free of faults. When checking the circuit fault, use the detection instrument to find out the fault position. After confirming that there is no poor contact fault, check the operation relationship between the circuit and the machine to avoid misjudgment, such as spot welding, seam welding, projection welding and supporting welding equipment.
山東自動(dòng)焊接設(shè)備
4.先靜后動(dòng)
4. static before dynamic
設(shè)備未通電時(shí),判斷焊接設(shè)備按鈕、接觸器、熱斷路器元件和熔斷器的質(zhì)量,從而判斷故障。通電測(cè)試,聽(tīng)聲音,測(cè)量參數(shù),判斷故障,然后進(jìn)行維修。如本文介紹焊接設(shè)備故障的檢查方法和維修經(jīng)驗(yàn)。當(dāng)電焊機(jī)輸入缺相,無(wú)法判斷三相電壓值時(shí),應(yīng)先聽(tīng)聲音,分別測(cè)量各相對(duì)點(diǎn)的電壓,才能判斷哪一相有缺陷。
When the equipment is not powered on, judge the quality of buttons, contactors, thermal circuit breaker elements and fuses of welding equipment, so as to judge the fault. Power on test, listen to the sound, measure the parameters, judge the fault, and then carry out maintenance. For example, this article introduces the inspection methods and maintenance experience of welding equipment faults. When the input phase of the electric welding machine is missing and the three-phase voltage value cannot be judged, the sound shall be heard first, and the voltage of each relative point shall be measured respectively, so as to judge which phase is defective.
5.先清后修
5. cleaning before repair
對(duì)于污染較重的焊接設(shè)備,清潔其按鍵、接線點(diǎn)、接觸點(diǎn),并檢查外控按鍵是否失靈。許多故障是由污垢和導(dǎo)電灰塵引起的,而故障往往在清洗后。特別是在建筑工地等惡劣環(huán)境中。
For heavily polluted welding equipment, clean its keys, wiring points and contact points, and check whether the external control keys fail. Many faults are caused by dirt and conductive dust, and faults are often eliminated after cleaning. Especially in harsh environments such as construction sites.
6.先主后輔
6. main before auxiliary
山東自動(dòng)焊接設(shè)備電源部分的故障往往占整個(gè)焊接設(shè)備故障的很大比例,所以先修理電源輸入部分往往可以事半功倍。然后檢查焊接設(shè)備的其他輔助部件,如行走、送絲等。
The power failure of Shandong automatic welding equipment often accounts for a large proportion of the whole welding equipment failure, so repairing the power input part first can often get twice the result with half the effort. Then check other auxiliary parts of the welding equipment, such as walking, wire feeding, etc.
對(duì)于調(diào)試和故障并存的焊接設(shè)備,必須在調(diào)試前排除故障。調(diào)試必須在電路完全無(wú)故障、接線正確(包括地線)的前提下進(jìn)行。在條件允許的情況下,必須先對(duì)焊接設(shè)備進(jìn)行絕緣電阻測(cè)試,然后再進(jìn)行調(diào)試或測(cè)試。如對(duì)這一問(wèn)題還存在任何疑問(wèn),都?xì)g迎關(guān)注我們網(wǎng)站http://niuniury.com并咨詢我們的工作人員,將竭誠(chéng)為您服務(wù)。
For welding equipment with both commissioning and fault, the fault must be eliminated before commissioning. The commissioning must be carried out on the premise that the circuit is completely fault free and the wiring is correct (including the ground wire). If conditions permit, the welding equipment must be tested for insulation resistance before commissioning or testing.
