What problems do sleeve wrenches use?
Methods: with special wrench precision adjustment key is inserted into the tail end hole Neishun Zhuanzeng clockwise torque value, counterclockwise rotation to reduce torque value.
Caution with torque wrench:1., pay attention to waterproof, mud, sand and other debris into the wrench handle, torque wrench is strictly prohibited when the use of hammer.2. when using the wrench head to be leveled, force should be uniform, not too hard or exert impact force.3. when the torque wrench issued a "click" sound, to immediately stop the wrench, wrench force to prevent damage to the part of the 4 set to zero in the wrench is strictly prohibited to use, because in this state after no sound signal, easy to overload damage wrenchWhen the 5. wrench is not suitable for a long time, the wrench scale shall be set on the zero position so as to avoid the fatigue failure of the force measuring element.6. during the process of use, if the wrench does not sound, the signal should be stopped immediately for maintenance. After maintenance, the wrench needs to be calibrated and can be used before calibration.
Torque wrench operation method: the new wrench factory inspection, product certification, the torque value is set at the lowest position. Before use, according to the reinforced joints and steel sleeve connection needs to connect the tightening torque, the traveling scale wrench on the value set in the corresponding position, namely use special wrench screw torsion reinforced specification scale on the scale of swimming alignment handle on the line, and then will be connected or stationary jaw bite bar sleeve. Hold the wrench handle clockwise, uniform strength, when the "KaKa" sound, can stop the afterburner, reinforced joint tightening torque values have reached the requirements.
The socket wrench is used for detecting the tightening torque value of the steel connecting sleeve and the connecting wire head of the steel bar.Steel joint sleeve torque wrench applicable range: This product applies to the diameter of 12- 40MM mm rebar connection, tightening torque test.Steel connecting sleeve torque wrench technical indicator: indication duty error / indication repetition error is less than or equal to 0.5%.Torque wrench for steel connecting sleeve specification: wrench arm arm length 600mm. Torque value setting range 70~370N.M.
