扭力扳手使用注意事項：
Precautions for use of torque wrench:
1、人們在選擇扭力扳手時，要根據(jù)螺栓或螺母的尺寸來選擇開口尺寸的扭力扳手。如果扭力扳手的開口尺寸大于螺栓或螺母的尺寸，那在使用時，容易滑脫并損傷螺件的六角。如果扭力扳手的開口尺寸太小，那無法嵌入到螺栓或螺母中進行扭動。
1. When selecting torque wrenches, people should select torque wrenches with open size according to the size of bolts or nuts. If the opening size of the torque wrench is larger than the size of the bolt or nut, it is easy to slip and damage the hexagon of the bolt when it is used. If the opening size of the torque wrench is too small, it cannot be inserted into the bolt or nut for twisting.
2、人們在使用扭力扳手時，為防止扳手損壞和滑脫，應(yīng)使拉力作用在開口較厚的一邊，如此才能用上力。另外，人們子啊使用扭力扳手時，要注意開口不能出現(xiàn) “八”字形，以免損壞螺母和扳手。
2. When people use torque wrenches, in order to prevent the wrench from damage and slipping, the tension should be applied to the side with the thicker opening, so that the force can be used. In addition, when people use torque wrenches, they should pay attention not to have an "eight" shaped opening to avoid damaging the nuts and wrenches.
3、扭力扳手是按人手的力量來設(shè)計的，人手力量越大，扭力扳手在旋轉(zhuǎn)螺紋、螺母時的力量越大。如果人們遇到較緊的螺紋件，用扭力扳手也不能使其松動的話，切記不能用捶打工具錘擊扳手，以免損壞扳手，人們可以適當調(diào)整扳手的用力方向，找到的發(fā)力點。另外，還要注意的是，除了套筒扳手能套裝加力桿，其他扳手都不能套裝加力桿，扭力扳手也不能。遇到無法擰動的螺紋緊固件，人民不能胡亂給扭力扳手加裝加力桿，以防損壞扳手或螺紋連接件。
3. The torque wrench is designed according to the strength of the human hand. The greater the strength of the human hand, the greater the strength of the torque wrench when rotating the thread and nut. If people encounter tight threaded parts and cannot loosen them with a torque wrench, remember not to hammer the wrench with a hammer tool to avoid damage to the wrench. People can adjust the direction of force of the wrench properly and find the force generating point. In addition, it should also be noted that except for socket wrenches, no other wrenches can be equipped with torque rods, nor can torque wrenches. When encountering threaded fasteners that cannot be screwed, people shall not randomly add torque rods to torque wrenches to prevent damage to wrenches or threaded connectors.
4、扭力扳手一般都帶有預設(shè)扭矩數(shù)值和聲響的裝置，當緊固件的擰緊扭矩達到預設(shè)數(shù)值時，扭力扳手能自動發(fā)出訊號“卡嗒”聲，同時伴有明顯的手感振動，這表示扭力扳手已經(jīng)將緊固件松好。將扭力扳手從緊固件上取下后，扳手各相關(guān)零件能自動復位。
4. The torque wrench is generally equipped with a device with preset torque value and sound. When the tightening torque of the fastener reaches the preset value, the torque wrench can automatically send out a signal "click" sound, accompanied by obvious hand vibration, which means that the torque wrench has loosened the fastener. After the torque wrench is removed from the fastener, all relevant parts of the wrench can be reset automatically.
5、扭力扳手一般是用來旋轉(zhuǎn)螺栓或螺帽的，扳轉(zhuǎn)時應(yīng)該使用拉力，推轉(zhuǎn)扳手更容易發(fā)生危險。人們在使用時，一定要注意這點。另外，扭力扳手可以用來松緊螺栓，螺栓旋緊前應(yīng)先將螺栓清潔并上潤滑油。
5. The torque wrench is generally used to rotate the bolt or nut. The tension should be used when turning, and the push wrench is more likely to cause danger. People must pay attention to this when using it. In addition, the torque wrench can be used to loosen and tighten the bolts. Before tightening the bolts, they should be cleaned and lubricated.
6、人們在使用扭力扳手旋緊螺栓時，應(yīng)均勻使力，不得利用沖擊力。簡單來說，是不要用錘擊工具來錘擊扳手，使其在短時間內(nèi)獲得沖擊力，從而帶動整只扳手旋轉(zhuǎn)，使扳手將螺栓旋緊，這種做法容易損壞扳手。
6. When people use a torque wrench to tighten the bolts, they should apply the force evenly and should not use the impact force. To put it simply, do not use hammering tools to hammer the wrench, so that it can obtain impact force in a short period of time, so as to drive the whole wrench to rotate, so that the wrench can tighten the bolt, which is easy to damage the wrench.
7、如果長期不用扭力扳手，那人們把扭力扳手的調(diào)節(jié)標尺刻線退扭矩小數(shù)值處，這樣可以延長扳手的使用壽命。
7. If the torque wrench is not used for a long time, people should withdraw the adjusting scale scale of the torque wrench to the small value of torque, which can extend the service life of the wrench.
