How long can a torque wrench last?
Torsion in physics should be called "torque" and "torque", is the object by a rotating cutting direction and object to force the moment, because of erroneous results, everyone said "torque".Simply put, torque = force multiplied by arm of arm. For example, the arm of the arm (that is, the wrench) is 1M long and exerts the force of 100N, and the torque is 100N.m. The concept of torque is explained by the lever principle in elementary school, defined as the distance between the vertical force and the center of rotation".
Torque wrench purchase parameters reference:1 、 handle, ergonomic design, comfortable grip, greatly reducing fatigue when high intensity operation.2, double scale, can accurately set the torque value.3, to set the torque value, send out a clear sound, and can feel a slight shock on the handle.4, the locking ring close to the mouth of the net, can avoid misoperation, change the set torque value.5, wrench length: 990MM.6. Drive size 3/4 inches.7 minimum calibration interval 1.8. Application torque shall be within 40% to 90% of the torque range of the wrench.9 、 press the torque to lock the nut.
Torque wrench, also known as torque wrench, torque wrench, torque adjustable wrench, is a wrench. According to the power source can be divided into: electric torque wrench, hydraulic torque wrench and manual torque wrench; manual torque wrench can be divided into: preset type, dial type and digital display.
Torque wrench can be used for 10 years, torque electric wrench features: easy to operate, time-saving and labor-saving, torque adjustable.
