In order to improve our work efficiency, we need to reduce the failure of torque wrench in use, so when users use torque wrench, they should learn to avoid the failure of torque wrench, and how to avoid it. Today, Xiaobian will explain how to reduce the failure of torque wrench, hoping to help you.

在选购扭力扳手之前，需要对加工设备和工作环境要求有一个简单认识，在进行比较中，能够很好的进 行性能优势分析。在型号、尺寸、扭力动力大小、类型等方面有一个认识。 具体的来说，判断扭力扳手性能优劣的标准有两大

Before purchasing torque wrench, we need to have a simple understanding of the requirements of processing equipment and working environment. In comparison, we can analyze the performance advantages very well. In the model, size, torque power size, type and other aspects of a comprehensive understanding. Specifically speaking, there are two standards to judge the performance of torque wrench

方面：功能优势是所有机器选购的标准，扭力扳手发挥***功用就需要保障有好的性能。这个时候需要参考扭力输出扭力大小，扭力动力源参数有哪些不足，扭力扳手设计是否人性化。

Aspect: function advantage is the standard for all machines to purchase, and the torque wrench should have good performance to play its function. At this time, we need to refer to the torque output torque, what are the shortcomings of the torque power source parameters, and whether the design of the torque wrench is humanized.

第二方面，扭力扳手性能优劣还需要考虑检修服务功能，了解扭力扳手的设计原理，工作强度，使用年限以及售后服务等，这些要素关联扭力扳手使用寿命和工作强度，用户在选购的时候一定不要忽 视。扭力扳手选购需要参考多方面数据，为了更好的满足生产加工需求，还需要注意科技创新与市场发展优势，这样就能够保障选购到更实用的扭力扳手。

Second, the performance of the torque wrench needs to consider the maintenance service function, understand the design principle, working strength, service life and after-sales service of the torque wrench. These factors are related to the service life and working strength of the torque wrench, and users must not ignore them when purchasing. In order to better meet the needs of production and processing, we also need to pay attention to the advantages of scientific and technological innovation and market development, so as to ensure the purchase of more practical torque wrench.
