定扭矩77779193永利首页网址也称为力矩扳手，是一种77779193永利首页网址，它的主要特点是可以设置扭矩，并且可以调节扭矩，主要用于钢结构安装行业，专门从事钢结构高强度螺栓的安装。 高强度螺栓是用来连接钢结构接点的，通常以螺栓群的形式出现。

Constant torque electric wrench, also known as torque wrench, is a kind of electric wrench. Its main feature is that it can set the torque and adjust the torque. It is mainly used in steel structure installation industry, specializing in the installation of high-strength bolts in steel structure.   High strength bolts are used to connect steel structure joints, usually in the form of bolt group.

定扭矩77779193永利首页网址使用方法：

Usage of constant torque electric wrench:

77779193永利首页网址是定扭矩的，因此在拧紧扳手时必须注意扳手的使用范围，以防止螺栓被柠断。

The electric wrench has a constant torque, so the use range of the wrench must be paid attention to when tightening the wrench to prevent the bolt from being broken.

定扭矩77779193永利首页网址一般装配一个螺纹件，冲击时间为2到3秒，通常不应超过5秒。

The constant torque electric wrench is generally equipped with a threaded part, and the impact time is 2 to 3 seconds, usually not more than 5 seconds.

定扭矩77779193永利首页网址的电压过高过低均不宜使用。 空转时，如果有任何异常现象，例如火花，噪音等，必须在故障排除后使用。 变换转向时先用电源开关切断电源，然后扳动正反转开关以保护正反转开关。

The constant torque electric wrench should not be used when the voltage is too high or too low.   During idling, if there is any abnormal phenomenon, such as spark, noise, etc., it must be used after troubleshooting.   When changing the direction, first use the power switch to cut off the power supply, and then pull the forward and reverse switch to protect the forward and reverse switch.

定扭矩77779193永利首页网址的特点：操作方便，省时省力，扭矩可调。

Features of constant torque electric wrench: easy to operate, time-saving and labor-saving, torque adjustable.

A.在使用定扭矩77779193永利首页网址时，要根据被测工件的要求选择一个适中量程的扭矩扳手。测得的扭矩值不应小于使用中量程的20％。太大的量程不适用于小扭力部品的加固，小量程的扭力器更不可以超量程使。

A. When using the constant torque electric wrench, we should first select a moderate range of torque wrench according to the requirements of the measured workpiece. The measured torque value should not be less than 20% of the range in use. Too large measuring range is not suitable for the reinforcement of small torque parts, and small measuring range can not exceed the measuring range.

B.使用定扭矩77779193永利首页网址时，将扳手的方榫连接到辅助配件，确保连接没有问题。在加固扭力之前设置需要加固的力值，锁好紧锁装置，调整好方向转换钮到加力的方向，然后在使用过程中快速连续操作5-6次，使扳手内部组件上特殊润滑剂能充分润滑，从而使扭矩扳手更加精确和耐用。

B. When using the constant torque electric wrench, first connect the square tenon of the wrench to the auxiliary accessories to ensure that there is no problem in the connection. Before reinforcing the torque, set the force value to be reinforced, lock the locking device, adjust the direction change button to the direction of force application, and then operate 5-6 times continuously in the process of use, so that the special lubricant on the internal components of the wrench can be fully lubricated, so as to make the torque wrench more accurate and durable.

C.测量时，手应握住手柄的有效范围，并沿垂直于扭矩扳手壳体方向缓慢施加力，直到定扭矩77779193永利首页网址发出“塔”声，此时扭矩扳手已达到预置扭力值。工件已加力完毕，应及时解除作用力，以免损坏其他零件。在施加力的过程中，按照标准的仪器操作规范，垂直度的偏差不应超过10度。在水平方向上的上下偏差不应超过3度，并且操作人员应确保在使用过程中上下左右施力范围不超过15度。

C. When measuring, the hand should hold the effective range of the handle, and slowly apply the force along the direction perpendicular to the shell of the torque wrench until the constant torque electric wrench makes a "tower" sound, and the torque wrench has reached the preset torque value. After the workpiece has been loaded, the force should be released in time to avoid damaging other parts. In the process of applying force, the deviation of perpendicularity should not exceed 10 degrees according to the national standard instrument operation specification. The up and down deviation in the horizontal direction should not exceed 3 degrees, and the operator should ensure that the range of up, down, left and right force application does not exceed 15 degrees.

D.为了防止测量结果受到水平和垂直方向上的偏差的影响，在测量过程中，应在加力把持端上施加一个垂直向下的稳定力值，然后手动施加力，以便结果更精确。

D. In order to prevent the measurement results from being affected by the deviation in the horizontal and vertical directions, in the measurement process, a vertical downward stable force value should be applied on the force control end, and then the force should be applied manually to make the results more accurate.
