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.

氣動扭矩扳手在使用前必須要確認氣源管路連接是否安裝牢固，壓縮空氣是否可靠，并檢查接頭是否漏氣。

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.

在檢查完之后根據(jù)所需扭矩值和螺栓規(guī)格選擇合適的扭矩套筒。將扭矩套筒插入氣動扭矩扳手的端口中，并保證安裝牢固。將扳手置于螺栓頭上，并啟動氣源供應(yīng)，待扭矩扳手達到預(yù)定扭矩時自動停機。如果需要反擰螺栓，請將方向盤設(shè)置為反轉(zhuǎn)位置，然后重新安裝扭矩套筒并重復(fù)上述步驟。

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.

在使用氣動扭矩扳手預(yù)緊完需要擰緊的螺栓之后，關(guān)閉氣源，從扭矩扳手上拆卸下扭矩套筒，再拆下扳手與氣源連接，清潔整個工具妥善保管即可。需要注意的是，在使用氣動扭矩扳手之前需要進行培訓(xùn)和操作指導(dǎo)，以確保正確的使用方法和操作。同時，還需要定期檢查和維護氣動扭矩扳手，以保證其正常的工作和使用壽命。

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.
