预置式扭力扳手使用注意事项!

扭力扳手是一种精 密控制螺栓和螺母锁紧力矩的专用工具,应按照下列要求正确使用:

Torque wrench is a special tool for precisely controlling the locking torque of bolts and nuts. It should be used correctly according to the following requirements:
1、不能使用预置式扭力扳手去拆卸螺栓或螺母。
1. Do not use a preset torque wrench to remove bolts or nuts.
2、严禁在扭力扳手尾端加接套管延长力臂,以防损坏扭力扳手。
2. It is forbidden to add a sleeve at the end of the torque wrench to extend the force arm to prevent damage to the torque wrench.
3、根据需要调节所需的扭矩,并确认调节机构处于锁定状态才可使用。
3. Adjust the required torque as required and confirm that the adjusting mechanism is locked before use.
4、使用扭力扳手时,应平衡缓慢地加载,切不可猛拉猛压,以免造成过载,导致输出扭矩失准。在达到预置扭矩后,应停止加载力量。
4. When using the torque wrench, it shall be loaded slowly and balanced, and shall not be pulled and pressed violently, so as to avoid overload and inaccurate output torque. After reaching the preset torque, the loading force shall be stopped.
5、预置式扭力扳手使用完毕,应将其调至小扭矩,使测力弹簧充分放松,以延长其寿命。
5. After the preset torque wrench is used, it shall be adjusted to a small torque to fully relax the force measuring spring, so as to prolong its service life.
6、应避免水分侵入预置式扭力扳手,以防零件锈蚀。
6. Avoid moisture intrusion into the preset torque wrench to prevent parts from rusting.
7、所选用的扭力扳手的开口尺寸必须与螺栓或螺母的尺寸相符合,扳手开口过大易滑脱并损伤螺件的六角,各类扳手的选用原则,一般优先选用套筒扳手,其次为梅花扳手,再次为开口扳手,选活动扳手。
7. 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 off and damage the hexagon of the screw. Generally, socket wrench is preferred, followed by ring wrench, open-ended wrench and movable wrench.
8、为防止扳手损坏和滑脱,应使拉力作用在开口较厚的一边,这一点对受力较大的活动扳手尤其应该注意,以防开口出现“八”字形,损坏螺母和扳手。
8. In order to prevent the wrench from being damaged and slipping, the pulling force shall act on the thicker side of the opening, which shall be paid special attention to the adjustable wrench with large force, so as to prevent the "eight" shape of the opening from damaging the nut and wrench.
9、扭力扳手是按人手的力量来设计的,遇到较紧的螺纹件时,不能用锤击打扳手;除套筒扳手外,其它扳手都不能套装加力杆,以防损坏扳手或螺纹连接件。
9. The torque wrench is designed according to the force of human hands. When encountering tight threaded parts, the wrench cannot be hit with a hammer; Except for the socket wrench, other wrenches shall not be sleeved with a booster rod to prevent damage to the wrench or threaded connector.
10、扭力扳手使用时,当听到“啪”的一声时,此时是合适的。
10. When the torque wrench is used, it is appropriate to hear a "snap" sound.
备注:
remarks:
1、用途:扭力扳手为旋转螺栓或螺帽的工具。
1. Purpose: torque wrench is a tool for rotating bolts or nuts.
2、用法:扭力扳手扳转时应该使用拉力,推转扳手极易发生危险。
2. Usage: tension should be used when turning the torque wrench. Pushing the wrench is very dangerous.
3、扭力扳可用于松紧螺栓,螺栓旋紧前应先将螺栓清洁并上润滑油。
3. The torque wrench can be used to loosen the bolts. The bolts should be cleaned and lubricated before tightening.
4、使用扭力扳手旋紧螺栓时应均匀使力,不得利用冲击力。
4. When tightening bolts with torque wrench, the force shall be uniform, and the impact force shall not be used.
