紧固件的拧紧程度是影响机电产品质量的因素之一,不少企业在装配中配备了一定数量的扭矩扳手。而扭矩扳手因弹性后效的作用,误差日趋增大,达不到准确度要求。从计量器具的管理角度看,应定期对扭矩扳手进行校验和检定。上海自动化仪表公司仪表铸锻厂向您推出该厂研制的扭矩扳手检定装置——GNJ系列扭矩校 Fastener tightening is one of the factors that affect the quality of mechanical and electrical products, many companies equipped with a certain number of torque wrenches in the assembly. The torque wrench due to the role of flexibility, the error is increasing, fail to meet the accuracy requirements. From the management point of view of measuring instruments, the torque wrench should be checked and calibrated on a regular basis. Shanghai Automation Instrumentation Company Casting and Forging Factory to introduce the factory developed torque wrench test device - GNJ Series Torque School
