Basic knowledge of pneumatic torque wrench

Pneumatic torque wrench is a kind of torque wrench with high pressure air pump as power source. Torque multipliers with three or more epicyclic gears are driven by one or two powerful pneumatic motors. The torque is controlled by adjusting the gas pressure. In order to allow a specific torque demand setting, each thing is equipped with a special air pressure first-to-torque comparison chart and proofreading report. In order to further use, the pneumatic torque wrench can be matched with a torque sensor to output more accurate torque. After obtaining the required torque, a suitable circuit system can be used to manually or actively shut down the air supply. The operation of the pneumatic torque wrench is quiet--

The company has professional and complete product pre-sale, In-sale and after-sales service processes, and has various torque tool accessories (digital torque wrench, preset torque wrench, dial torque wrench, torque wrench detector, multiplier, hydraulic torque wrench, electric wrench, etc.), to provide customers with thoughtful consultation and service. 1. When using a torque wrench, it should be balanced and loaded slowly, and must not be yanked and pressed, so as not to cause overload and cause the output torque to be inaccurate. After the preset torque is reached, the loading shall be stopped. 2. Do not use preset torque wrench to remove bolts or nuts 3. It is strictly prohibited to add a sleeve extension arm at the end of the torque wrench to prevent damage to the torque wrench. 4. Adjust the required torque as required and confirm that the adjustment mechanism is in a locked state before use. 5. After the preset torque wrench is used, it should be adjusted to a small torque to fully relax the force measuring spring to extend its life. 6, should avoid water intrusion preset torque wrench, to prevent parts corrosion. 7. The opening size of the selected torque wrench must be consistent with the size of the bolt or nut. If the opening of the wrench is too large, it is easy to slip off and damage the hexagon of the screw. In the maintenance of imported cars, attention should be paid to the choice of the wrench metric inch system. 8, the selection principle of all kinds of wrench, generally give priority to the socket wrench, followed by the ring wrench, again for the open-end wrench, after the selection of adjustable wrench. In order to prevent the wrench from being damaged and slipping off, the pulling force should be applied to the thicker side of the opening. This should be paid special attention to the adjustable wrench with large force to prevent the opening from appearing "eight" shape and damaging the nut and wrench.

Torque wrench you really use right?

When installing carbon fiber parts and lightweight parts, the degree of tightening and uniformity of screws are particularly important, and the indicator to measure these two elements is the torque during installation. Within the correct torque range, it can not only clamp the parts, but also prevent tooth sliding or damage. Therefore, the torque wrench has become a necessary tool for car shops and professional riders. What else do we need to pay attention to in use? Strictly speaking, the torque wrench is a measuring instrument. In particular, the mechanical preset torque wrench commonly used in the industry can only be used to determine the torque when tightening the screw, and must not be used as a disassembly tool to loosen the tightened screw. The preset torque wrench is usually used in one direction. When the screw is tightened clockwise and the preset torque is reached, the connecting rod is pushed to produce an instantaneous disjoint effect and a prompt sound. Although it can be switched to counterclockwise operation by the paddle of the ratchet, it can only be used to unscrew the loose screw. The principle is that the static friction force in the screw fastening state is far greater than the dynamic friction force in the loose state, especially after the screw is installed for a period of time, the torque required to loosen the screw is much greater than the torque when tightening (up to 1.5 times). Reverse use is easy to cause the internal lever of the wrench to jam, resulting in no prompt during forward use, causing irreversible damage.

Operation steps of torque wrench

The use of torque wrenches should not be underestimated. From the perspective of use, their general operations are the same, and their use process can be divided into two main steps: adjusting torque and tightening bolts. Specific to understand the following. Adjusting torque: The adjustment of the torque of the torque wrench needs to be determined according to its fastening object. The torque is adjusted according to the size of the fastening object and a fixed value of torque is set. During this operation, it should be noted that the adjustment of the torque to the setting should be completed only after hearing the news, and the locking ring should be kept close to its own position after the torque is set. As for the specific torque value, it is appropriate that the wrench can lock the nut. Fastening bolts: After setting the torque, you can start to tighten the bolts. Pay attention to the strength when tightening. Among them, the intensity of operation should be moderate, so as to avoid the fastening effect and poor efficiency caused by too small intensity, and the bolt damage caused by too large intensity. And in the process of tightening the bolt, if you feel that the torque is too loose, you can still stop the tightening operation, and then continue and complete the tightening of the bolt after adjusting and setting the torque. The main function of the torque wrench is tightening, and the corresponding work can be done very advantageously through the operation of these two steps.
