很多有稳定气源的生产车间或者对用电有限制的易燃易爆工况环境无疑气动扭矩扳手是扭矩精准且操作的设备安装预紧工具。很多用户可能对液压扳手、电动力矩扳手的使用方法比较熟悉，并不清楚气动力矩扳手使用方法，今天我们就来了解下。
Many production workshops with stable gas sources or flammable and explosive working conditions with limited electricity usage undoubtedly have pneumatic torque wrenches as equipment installation pre tightening tools with precise torque and safe operation. Many users may be familiar with the use of hydraulic wrenches and electric torque wrenches, but are not familiar with the use of pneumatic torque wrenches. Today, we will take a look.
气动扭矩扳手在使用前必须要确认气源管路连接是否安装牢固，压缩空气是否可靠，并检查接头是否漏气。
Before using a pneumatic torque wrench, it is necessary to confirm whether the air supply pipeline connection is securely installed, whether the compressed air is reliable, and check whether the joint is leaking.
在检查完之后根据所需扭矩值和螺栓规格选择合适的扭矩套筒。将扭矩套筒插入气动扭矩扳手的端口中，并保证安装牢固。将扳手置于螺栓头上，并启动气源供应，待扭矩扳手达到预定扭矩时自动停机。如果需要反拧螺栓，请将方向盘设置为反转位置，然后重新安装扭矩套筒并重复上述步骤。
After inspection, select a suitable torque sleeve based on the required torque value and bolt specifications. Insert the torque sleeve into the port of the pneumatic torque wrench and ensure that it is securely installed. Place the wrench on the bolt head and start the air supply, and automatically stop when the torque wrench reaches the predetermined torque. If it is necessary to reverse tighten the bolts, set the steering wheel to the reverse position, then reinstall the torque sleeve and repeat the above steps.
在使用气动扭矩扳手预紧完需要拧紧的螺栓之后，关闭气源，从扭矩扳手上拆卸下扭矩套筒，再拆下扳手与气源连接，清洁整个工具妥善保管即可。需要注意的是，在使用气动扭矩扳手之前需要进行培训和操作指导，以确保正确的使用方法和操作。同时，还需要定期检查和维护气动扭矩扳手，以保证其正常的工作和使用寿命。
After using a pneumatic torque wrench to pre tighten the bolts that need to be tightened, turn off the air source, remove the torque sleeve from the torque wrench, and then remove the wrench from the air source connection. Clean the entire tool and keep it properly. It should be noted that training and operational guidance are required before using pneumatic torque wrenches to ensure correct usage and safe operation. At the same time, it is also necessary to regularly inspect and maintain the pneumatic torque wrench to ensure its normal operation and service life.
