電動扳手是給電源或蓄電池供電的扳手，是擰緊螺栓的工具。電動扳手主要用于鋼結構安裝行業，從事鋼結構高強螺栓的安裝，高強螺栓是用來連接鋼結構的接觸件，通常以螺栓組的形式出現。不管電動扳手的質量有多好，都會因為長時間高強度的工作和高頻率的使用而出現故障或磨損問題，讓下面的電動扳手廠家教你如何修理電動扳手吧!
Electric wrench is a wrench for power supply or battery power supply. It is a tool for tightening bolts. Electric wrench is mainly used in steel structure installation industry, specializing in the installation of high-strength bolts in steel structure. High-strength bolts are used to connect the contact parts of steel structure, usually in the form of bolt groups. No matter how good the quality of the electric wrench is, there will be problems of failure or wear due to long time, high intensity work and high frequency use. Let the following electric wrench manufacturers teach you how to repair the electric wrench!
1. 有時我們會發現電動扳手通電后不轉，所以我們需要檢查電源插座是否插好。如果沒有問題，有必要看看電動扳手的內部電路是否有問題，可以使用的拆卸工具進行拆卸檢查。
1. Sometimes we find that the electric wrench does not turn when it is energized, so we need to check whether the power outlet is plugged in properly. If there is no problem, it is necessary to see if the internal circuit of the electric wrench is defective. Professional disassembly tools can be used for disassembly inspection.
2、如有電火花扳手，則可能是內部冷卻部件，應及時更換。
2. If there are spark wrenches, they may be internal cooling components and should be replaced in time.
3、有時候電動扳手卡不進緊固件的問題，需要檢查一下電動扳手的零件是否太緊，我們可以拿潤滑油來加工它。
3. Sometimes the electric wrench does not clip the fastener. We need to check whether the parts of the electric wrench are too tight. We can process it with lubricant.
4. 如果由于使用時間過長導致內部零件老化無法修復，只能聯系維修部門來。
4. If the aging of internal parts can not be repaired due to the long use time, it can only be solved by contacting the maintenance department.
此外，不要使用電動扳手超過五個小時，甚高端電動扳手也很容易損壞。
In addition, do not use electric wrenches for more than five hours, even high-end electric wrenches are easy to damage.
