The working principle of torque wrench testers

torque wrench testers card tower sound principle is very simple, can be divided into the following steps to understand: 1, the torque wrench in a "tower" sound of prompting has reached after you claim on the torque value;

2, "tower card" is issued by a torque wrench by itself of the internal structure of torque to release them to release the joint structure is divided into spring pressure, torque, torque of plunger, three structure.

3, first on the torque wrench set the required torque value, locking 100ton hydraulic jacks, began to tighten the bolt. After when the bolt to the torque value, can produce effect disconnect to the moment. At the moment have a disconnect effect issued a joint percussion, wrench metal case of "tower" sound. From this reminder to confirm to the torque value.

hydraulic torque wrench chart

hydraulic torque wrench chart is also called the torque wrench, torque is the product of the force and distance, when the thread fasteners such as fastening screw bolt and nut torque size needs to be controlled, to ensure that the thread fastening and not because of destruction of the torque is too large, so use the torque wrench to operate. First set a maximum torque, torque reaches the set value when, wrench "card tower" noise or wrench joint bending Angle, this is already tightening torque. Torque wrench can be divided into: preset torque wrench, torque wrench calibration tool, MINI type torque wrench, torque wrench, dial torque wrench set value.

Method of use torque wrench calibrators

A. in the use of the torque wrench calibrators, first of all, according to the requirement of the measurement of workpiece, selecting moderate range torque wrench, torque values measured is less than twenty percent of the torsion device in use range, should not be too great A range for small torsion part of reinforcement, small range of torsion is less can outrange that;

B. when using hydraulic bolt tensioning equipment, wrench square tenon connection first good auxiliary accessories (e.g., sleeve, all kinds of batch of mouth), ensure that the connection has no problem. Before strengthening torsion, set need reinforcement force value, and lock the lock device, adjust direction switch knob to the strength of the direction, then when use fast for 5 to 6 times in a row, first make a wrench on the internal components special lubricant can sufficient lubrication, make more accurate torque wrench, durable use.

C. measurement, hand to grasp the handle range, along the direction perpendicular to the torque wrench shell, strength slowly, until they hear the sound of the torque wrench issued a "tower", the torque wrench has reaches the preset torque value, the artifact has strength, and then immediately lift force, so as not to damage the other parts. According to the national standard in the process of applying, instrument operation specification, about its verticality deviation should not be more than 10 degrees. The horizontal deviation shall not be more than 3 degrees from top to bottom, the operator shall guarantee that the up and down or so in the process of use force application scope not more than 15 degrees;

D. in order not to make the deviation of measurement results for the horizontal and vertical direction and effect, when measuring should be applied on the strength of end of a vertical downward strength, stability and then manually add some force, such use value more accurate.

E. the reading of the torque wrench: if it is with table torsion instrument, directly read pointer indicated data to measure value; Sleeving and if it is a dial indicator, should first read the scale value on the scale, scale and vice or differential cylinder on the scale value to measure the sum of the data values.

F. torque wrench is a measuring tool, to should take put down gently, not a substitute for hammer knock, need not when please note set to the minimum torque, stored in a dry place. Torque wrench has a wide application scope, the reinforcement force, was relatively simple, only need to set the required torque value can operate
