桥梁建立专用定扭矩电动扳手--X20J-1运用简介
Special Electric Spanner with Constant Torque for Bridge Construction--Brief Introduction of X20J-1 Application
随着变革开放的深化开展，基建日益增加，桥梁建立更是必不可少。栓接是桥梁建立的主要衔接方式。栓接必需用大六角高强度螺栓。
With the deepening of China's reform and opening up, China's infrastructure is increasing day by day, and the establishment of bridges is even more indispensable. Bolting is the main connection mode of bridge construction. Large hexagonal high strength bolts are necessary for bolting.
大六角高强度螺栓普通是10.9级或12.9级，依据高强度螺栓施工工艺请求，高强螺栓的施工，必需先初紧，再终紧。初紧普通是比较大扭矩值的50%-60%；而终紧必需严厉到达螺栓规则的比较大扭矩值。
Large hexagonal high strength bolts are usually 10.9 or 12.9 grade. According to the requirements of construction technology of high strength bolts, the construction of high strength bolts must be initially tightened and then finally tightened. Initial tightening is usually 50% - 60% of the maximum torque value, while final tightening must reach the maximum torque value of bolt rules strictly.

大六角高强度螺栓施工，初紧能够选择手动力矩扳手、定扭矩电动扳手，而终紧必需选择运用前田定扭矩电动扳手。
In the construction of large hexagonal high strength bolts, the initial tightening can choose the hand power moment wrench and the fixed torque electric wrench, while the final tightening must choose the front field constant torque electric wrench.
桥梁建立选用螺栓普通是M24和M30大六角高强螺栓，其中M24比较大扭矩值普通是860Nm（比较大扭矩值依据摩擦系数不同，而不同），M30比较大扭矩值普通是1700Nm（比较大扭矩值依据摩擦系数不同，而不同）
The bolts used in bridge construction are usually M24 and M30 large hexagonal high strength bolts. The maximum torque of M24 is 860Nm (the maximum torque is different according to the friction coefficient), and that of M30 is 1700Nm (the maximum torque is different according to the friction coefficient).
初紧时，需求选定扭矩电动扳手，设置初紧扭矩值，开端打螺栓，紧固几秒钟后，电动扳手中止紧固，抽出套筒即可。
In the initial tightening, it is necessary to select the torque electric wrench, set the initial tightening torque value, start bolting, tighten for a few seconds, then stop the tightening of the electric wrench and pull out the sleeve.
终紧时，需求定扭矩电动扳手，也是先设置扭矩值，到螺栓的比较大扭矩值。紧固几秒后，电动扳手中止紧固，抽出即可。
When the final tightening, the fixed torque electric wrench is required. It is also the first time to set the torque value to the maximum torque value of the bolt. After a few seconds of tightening, the electric wrench stops tightening and pulls out.
初紧能够选择普通定扭矩电动扳手，而终紧时，由于扭矩大、并且请求误差小，精度请求高，所以必需选择定扭矩电动扳手。电动扭矩扳手
The initial tightening can select the ordinary fixed torque electric wrench, while the final tightening, because of the large torque, small request error and high precision request, it is necessary to choose the fixed torque electric wrench. Electric Torque Spanner
