电动扭矩扳手的测试方法主要采用简单的测试设备，通过手动加载实现，存在精度低，功能简单，效率低的问题。 国外专用的扭矩测试设备可以达到很高的检测效率，但是价格昂贵，并且难以维护和扩展。 上述因素严重影响了扭矩扳手的生产和检查。 在现代测控技术中，智能仪表，总线仪表，虚拟仪表等微机测控仪表都充分利用了计算机的软硬件优势，不仅增强了参数的测量和处理功能，而且提高了性能。 指标。
The test method of electric torque wrench mainly adopts simple test equipment, which is realized by manual loading, which has the problems of low precision, simple function and low efficiency. Foreign special torque testing equipment can achieve high detection efficiency, but it is expensive and difficult to maintain and expand. These factors seriously affect the production and inspection of torque wrench. In modern measurement and control technology, intelligent instrument, bus instrument, virtual instrument and other microcomputer measurement and control instruments make full use of the advantages of computer software and hardware, which not only enhance the function of parameter measurement and processing, but also improve the performance.

由于中国尚未建立工业应用中螺栓紧固的相关标准，并且人力资源相对便宜，因此许多风力涡轮机安装单元仍保留相对落后的螺栓紧固方法。 传统的螺栓拧紧方法，即增加锤击力的扳手，操作简单，但无法获得准确可靠的螺栓残余载荷，严重威胁了风力发电机的安全运行。 随着国内风力发电行业的发展以及对风机采购和维护投资的增加，对传统螺栓紧固方法的改革和先进工具的提供势在必行。 使用普通的敲击扳手或扭矩倍增器或液压扳手进行初始锁定后，根据螺栓强度等级和其他条件比较螺栓和螺母尺寸及扭矩值表，然后使用高精度扭矩扳手进行精确的锁定操作， 可以大大提高风扇的安全性。

Due to the fact that China has not yet established relevant standards for bolt tightening in industrial applications, and human resources are relatively cheap, many wind turbine installation units still retain relatively backward bolt tightening methods. The traditional bolt tightening method, that is, the wrench with increasing hammering force, is easy to operate, but can not obtain accurate and reliable bolt residual load, which seriously threatens the safe and efficient operation of wind turbine. With the development of domestic wind power industry and the increase of wind turbine procurement and maintenance investment, it is imperative to reform the traditional bolt fastening method and provide advanced tools. After initial locking with ordinary percussion wrench or torque multiplier or hydraulic wrench, the size and torque value table of bolt and nut are compared according to the strength grade of bolt and other conditions, and then the precise locking operation is carried out by using high-precision torque wrench, which can greatly improve the safety of the fan.
电动扭矩扳手作为一种精密设备，风力涡轮机在自然条件差的领域中可以长期运行。 为了确保风力涡轮机的长期有效运行，有必要注意风力涡轮机上的每个细节，并仔细维护每个组件。 风力涡轮机的外观主要由四个部分组成：塔架，机舱，轮毂和叶片。 并且这四个部分需要通过螺栓连接。 因此，在风力涡轮机的安装过程中，螺栓紧固的有效性将直接影响未来风力涡轮机的正常运行和发电效率，尤其是塔架，机舱转向座椅轴承和 刀片。
As a kind of precision equipment, electric torque wrench can operate for a long time in the field of poor natural conditions. In order to ensure the long-term effective operation of the wind turbine, it is necessary to pay attention to every detail on the wind turbine and carefully maintain each component. The appearance of a wind turbine consists of four parts: Tower, cabin, hub and blade. And these four parts need to be connected by bolts. Therefore, in the process of wind turbine installation, the effectiveness of bolt tightening will directly affect the normal operation and power generation efficiency of future wind turbine, especially tower, cabin, steering seat, bearing and blade.
气动扭矩扳手可提供精确的扭矩控制，重复精度为±5％，配备传感器和电磁阀开关，重复精度可达到±2％。 气动扭矩扳手由于具有体积小，重量轻，单位重量输出功率高等特点，广泛用于航空航天，矿山，石油化工，铁路，建筑等领域，可实现高扭矩输出，反作用力小，对环境污染小， 且价格低廉。 重型车辆的组装和维护，重型设备的装卸等广泛用于产品生产和组装线，特别是在需要大扭矩的地方。
The pneumatic torque wrench can provide accurate torque control with a repetition accuracy of ± 5%. Equipped with sensors and solenoid valve switches, the repeatability accuracy can reach ± 2%. Pneumatic torque wrench is widely used in aerospace, mining, petrochemical, railway, construction and other fields due to its small size, light weight and high output power per unit weight. It can achieve high torque output, small reaction force, small environmental pollution and low price. The assembly and maintenance of heavy vehicles and the loading and unloading of heavy equipment are widely used in product production and assembly line, especially in places where high torque is required.
