定扭矩电动扳手使用要注意什么?

1、定扭矩电动扳手接通电源前应先查看电源电压是否与本产品铭牌相符,是否有接地装置。当电源电压超出+10%时应采取稳压措施,否则会影响控制精度。接地不良易造成事故。
1. Before the constant torque electric wrench is connected to the power supply, check whether the power supply voltage is consistent with the product's nameplate and whether there is a grounding device. When the power supply voltage exceeds + 10%, voltage stabilizing measures should be taken, otherwise the control accuracy will be affected. Poor grounding is easy to cause accidents.
2、定扭矩电动扳手使用的环境温度为-10℃-40℃,过高过低都会影响控制精度。
2. The environmental temperature of constant torque electric wrench is - 10 ℃ - 40 ℃, too high or too low will affect the control accuracy.
3、被拧螺栓的初始扭力不得大于工具的额定扭力的70%。螺栓达到额定扭力后不得重拧。
3. The initial torque of the screwed bolt shall not be greater than 70% of the rated torque of the tool. The bolts shall not be re tightened after reaching the rated torque.
4、工具用于拆卸螺栓时,其扭力不得大于额定扭力值。一般情况下,不是本扳手拧紧的或锈蚀严重的螺栓,不宜用本扳手拆卸,以免造成工具损坏。
4. When the tool is used to remove the bolt, its torque shall not be greater than the rated torque value. Generally, bolts that are not tightened or seriously rusted by this wrench should not be removed by this wrench to avoid tool damage.
5、变换旋转方向时,必须待电机停止转动后进行,严禁在运转中拨动正反开关。
5. When changing the direction of rotation, it must be carried out after the motor stops rotating. It is strictly forbidden to move the positive and negative switches during operation.

6、当扳手自动停止后即可松开开关(如果不断开开关,过5秒钟扳手就会自行启动)待4-5秒后再进行开动扳手,否则扳手不能启动。
6. When the wrench stops automatically, the switch can be released (if the switch is opened continuously, the wrench will start automatically after 5 seconds) and the wrench can be started after 4-5 seconds, otherwise the wrench cannot be started.
7、螺栓直径的大小对控制精度有一定的影响,施工中应用相同型号的螺栓连接付来标定扭力值,而且使用一段时间后还应进行检验校定。
7. The size of the bolt diameter has a certain impact on the control accuracy. In the construction, the same type of bolt connection pair is used to calibrate the torque value, and it should be checked and calibrated after a period of time.
8、工作前应开机空转3-5分钟。操作中如发现电机火花大,声音异常,扭力不稳定时,应立即停机检查,切勿带病工作。
8. Start the machine and idle for 3-5 minutes before operation. If the motor sparks, abnormal sound and unstable torque are found during operation, stop the machine immediately for inspection and do not work with diseases.
9、定期清洗和更换油脂,一般在工作5000次后,应进行一次清洗加油,以延长使用寿命。
9. Clean and replace the grease regularly. Generally, after 5000 times of operation, clean and add oil once to prolong the service life.
10、主机上的电源开关,碳刷,控制仪上的保险丝等均属易损件,容易引起故障,应经常检查,及时更换。
10. The power switch, carbon brush and fuse on the controller of the main engine are all vulnerable parts, which are easy to cause faults. They should be checked frequently and replaced in time.
11、使用中如发现工具上的螺钉松动,应及时紧固。
11. If the screw on the tool is found to be loose during use, it should be tightened in time.
12、搬运工具时不可提拉电缆线,并注意轻拿轻放,防止震动和摔碰。不用时应放在通风干燥处。如发现受潮应及时进行干燥处理。不可与酸、碱等有害物质气体接触或存放在一起。
12. When handling tools, do not lift or pull cables, and pay attention to handle with care to prevent vibration and falling. When not in use, it should be placed in a ventilated and dry place. In case of damp, it should be dried in time. Do not contact or store with acid, alkali and other harmful substances.
