Maintenance and management of electric torsion wrench:

由于電動扭剪扳手是高頻應用工具，為了提高測量精度，有必要定期校準和檢查工具，并配置滿足使用要求的電動扭剪扳手設備。目前，電動扭剪扳手主要由檢定儀對電動扭剪扳手進行校準，檢定儀需要定期檢查。由于校準環(huán)境是試驗室環(huán)境，因此與現(xiàn)場操作環(huán)境有很大的不同。

As the electric wrench is a high-frequency application tool, in order to improve the measurement accuracy, it is necessary to calibrate and inspect the tool regularly, and configure the electric wrench equipment to meet the use requirements. At present, the electric torque wrench is mainly calibrated by the calibrator, which needs to be checked regularly. Because the calibration environment is a laboratory environment, it is very different from the field operation environment.

為了確保校準管理的有效性，有必要參考實際使用現(xiàn)場進行管理，并且要求誤差不受使用場合的影響。使用前要注意檢查電動扭剪扳手的準確性，并根據(jù)使用頻率調(diào)整校準和維護的頻率。通常每年不少于一次，利用維護管理手段保證電動扭剪扳手的準確性。

In order to ensure the effectiveness of calibration management, it is necessary to refer to the actual use site for management, and the error is not affected by the use of occasions. Before use, pay attention to check the accuracy of the electric wrench, and adjust the frequency of calibration and maintenance according to the frequency of use. Usually not less than once a year, the use of maintenance management means to ensure the accuracy of electric torque wrench.

電動扭剪扳手的正確使用方法：

The correct use of the electric wrench is as follows:

電動扭剪扳手主要用于安裝緊固件，例如螺栓，螺釘和螺母。通過扭矩控制，確保了螺紋的擰緊，并且不會因扭矩過大而損壞螺紋。因此，有必要使用電動扭剪扳手進行扭矩值固定操作，在施加過程中需要預先設置固定扭矩值。當達到設定值時，電動扭剪扳手將發(fā)出提醒信息，可以感覺到手部振動或聽到“喀噠”聲，即扭矩已完成。

Electric wrench is mainly used to install fasteners, such as bolts, screws and nuts. Through torque control, the tightening of thread is ensured, and the thread will not be damaged due to excessive torque. Therefore, it is necessary to use the electric torque wrench to fix the torque value, and the fixed torque value needs to be set in advance during the application process. When the set value is reached, the electric wrench will send out a reminder message, and you can feel the hand vibration or hear the "click" sound, that is, the torque has been completed.

當扭矩值達到固定位置時，無需繼續(xù)施加力。 請勿使用沖擊力，停止施加力后，各個零件復位。 施加扭矩時，將手握在電動扭剪扳手手柄的中間刻度線上，并僅在電動扭剪扳手指示的方向上施加力，同時施力方向應在±15°以內(nèi)（垂直方向和水平方向）。

When the torque value reaches a fixed position, there is no need to continue to apply force. Do not use impact force. After the force is stopped, all parts will be reset. When the torque is applied, hold the hand on the middle scale line of the handle of the electric torsional shear wrench, and apply the force only in the direction indicated by the electric torsional shear wrench, and at the same time, the direction of force application should be ± fifteen ° Within (vertical and horizontal).

根據(jù)緊固件的強度和扭矩用以使用合適量程的扳手，并且不允許超過扳手的適用范圍。扳手在使用前需要調(diào)零，無荷載時注意對扭矩扳手指針的檢查，看指針是否在零標度值上，如果不是則需要對其進行調(diào)整。

According to the strength and torque of the fastener, the wrench with appropriate range shall be used, and the application scope of the wrench shall not be exceeded. The wrench needs to be adjusted to zero before use. When there is no load, pay attention to check the pointer of the torque wrench to see whether the pointer is on the zero scale value. If not, it needs to be adjusted.

為確保讀數(shù)準確，在使用過程中需要用一只手握住扳手的手柄，使扭矩扳手和拉力保持直角，并穩(wěn)定地施加力。當指針指向扭矩值時，禁止用力過大，否則會出現(xiàn)誤差值。測量完成后，旋轉(zhuǎn)旋鈕將指針返回到零位，以便進行下一個應用。作為測量工具，必須注意保護電動扭剪扳手。禁止進行扔擲、震動以及敲擊等

In order to ensure accurate reading, it is necessary to hold the handle of the wrench with one hand in the process of use, so that the torque wrench and the tension are kept at right angles, and the force is applied stably. When the pointer points to the torque value, do not use too much force, otherwise the error value will appear. After the measurement, rotate the knob to return the pointer to the zero position for the next application. As a measuring tool, we must pay attention to protect the electric wrench. Throwing, shaking and knocking are prohibited
