定扭矩电动扳手注意事项

来源:http://fhgfx.com 日期:2021-04-09 发布人:admin

接通电源前应先查看电压是否与本产品相符,是否有接地装置。当电源电压超出+-10%时应采稳压措施,不然会影响控制精度。接地不良造成事故。

Before switching on the power supply, check whether the voltage is consistent with the famous brand of the product and whether there is grounding device. When the power supply voltage exceeds + - 10%, the voltage stabilizing measures should be taken, otherwise the control accuracy will be affected. Poor grounding causes accidents.
工具使用的环境温度为-10-40,过高过低都会影响控制精度。被拧螺栓的初始扭矩不得大于工具额定扭矩的70%。螺栓达到额定扭矩后不得重拧。工具用于拆卸螺栓时,其扭矩不得大于额定扭矩值。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。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。
The ambient temperature of the tool is - 10-40, too high or too low will affect the control accuracy. 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. 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. 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.
当扳手自动停止后即可松开开关(如果不断开开关,过5秒钟扳手就自行启动)待4-5秒后再行开动扳手,否则扳手不能启动。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矩值,而且使用一段时间后还应进行检验校定。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,扭矩不稳定等,应立即停机检查,切勿带病工作。
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 will not start. 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. Before work, start the machine and idle for 3 ~ 5 minutes. 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.
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,以延长使用时间。主机上的电源开关,炭刷,控制仪上的保险丝等均属易损件,且易引起故障,应经常检查,及时更换。使用中如发现工具上的螺钉松动,应及时紧固。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、大碱等有害物质气体接触或存在。
Clean and replace the grease regularly. Generally, after 5000 times of work, clean and refuel once to prolong the service time. 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. If the screw on the tool is found to be loose during use, it should be tightened in time. 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. If it is found to be damp, it should be dried in time. Do not contact or exist with acid, alkali and other harmful substances.
