Usage and precautions of torque wrench

使用预设扭矩扳手的注意事项:扭矩扳手是精确控制螺栓螺母锁紧扭矩的专用工具，应按照以下要求正确使用:

Precautions for using preset torque wrench: torque wrench is a special tool to accurately control the locking torque of bolts and nuts, which should be used correctly according to the following requirements:

(1)不要使用预设扭矩扳手拆卸螺栓或螺母。

(1) Do not use a preset torque wrench to remove bolts or nuts.

(2)严禁在扭矩扳手末端增加套筒延长臂，以防损坏扭矩扳手。

(2) It is strictly forbidden to add a socket extension arm at the end of the torque wrench to prevent damage to the torque wrench.

(3)根据需要调整所需扭矩，确认调整机构处于锁定状态后方可使用。

(3) Adjust the required torque as required, and confirm that the adjustment mechanism is in the locked state before use.

(4)使用扭矩扳手时，要平衡缓慢加载，切勿猛拉猛压，以免造成过载和输出扭矩不对中。达到预设扭矩后，应停止加载力。

(4) When using the torque wrench, it is necessary to balance and load slowly, and do not pull and press violently, so as to avoid overload and misaligned output torque. When the preset torque is reached, the loading force shall be stopped.

(5)使用预设的扭矩扳手后，应将其调整到更小扭矩，使施力弹簧充分放松，以延长其使用寿命。

(5) After using the preset torque wrench, it should be adjusted to the minimum torque to fully relax the force spring, so as to extend its service life.

(6)避免水侵入预设扭矩扳手，防止零件生锈。所选扭矩扳手的开口尺寸必须与螺栓或螺母的尺寸一致。如果扳手的开口太大，很容易滑落，损坏螺钉的六角。根据各种扳手的选择原则，一般套筒扳手，其次是环形扳手，再次是开口扳手，是活动扳手。为防止扳手损坏和滑脱，应将拉力施加在开口较厚的一侧，特别注意受力较大的活动扳手，防止开口呈“八”字形，损坏螺母和扳手。

(6) Avoid water intrusion into the preset torque wrench to prevent parts from rusting. The opening size of the selected torque wrench must be consistent with the size of the bolt or nut. If the opening of the wrench is too large, it is easy to slip and damage the hexagon of the screw. According to the selection principles of various wrenches, socket wrenches are generally preferred, followed by ring wrenches, open-end wrenches, and finally adjustable wrenches. In order to prevent the wrench from being damaged and slipping, the tension should be applied to the side with thick opening, and special attention should be paid to the spanner with large force to prevent the opening from being "eight" shaped and damaging the nut and wrench.
