Instruction

through continuous power supply makes the quality of a certain object rotate faster, then in an instant into the output shaft, which can obtain the bigger torque output.
Compressed air is the most common source of power, but also have the use of electric or hydraulic, do with battery power supply of torque wrench is also very popular.
Pneumatic wrench is widely used in many industries, such as car repair, heavy equipment maintenance, product assembly (usually referred to as the "pulse tools" and specifically designed for precise torque output), the major construction projects, installation of steel wire, a screw and any other parts of the high torque output.

Air wrench can be in every standard socket ratchet drive size, from small 1/4 "drive team of tool to install and disassemble, to 3.5".
Air wrench generally does not apply to fastening device ontology for the installation of the ceramic, plastic fastening pieces.

Principle

Pneumatic torque wrench is a kind of high pressure pump as the power source of torque wrench.Is composed of one or two powerful pneumatic motor to drive with three or more turnover gear torque multiplier.Through adjusting the air pressure to control the size of torque, to allow specific torque requirements set, each tool is equipped with a dedicated air pressure to the torque control charts and to correct the report first.And to further application of pneumatic torque wrench can match torque sensor at the same time, make the output torque is more accurate.After getting the required torque can use the right loop system to manually or automatically to close the gas source.
Pneumatic torque wrench is a kind of hand-held rotary pneumatic tools, torque can be accurately set, used to complete the lock nut and bolt or remove work;Control part through voltage regulator and power management system implementation, the mechanical part adopts planetary gear retarding mechanism
Pneumatic torque wrench operation is quiet - less than 85 db (A), absolutely no impact, reduce the damage to tools, sleeve and locked, these two factors can make tools, operating comfort, reduce fatigue, improve security, maximum torque of 300000 N.m.
Provide the accurate torque control pneumatic torque wrench - duplication is plus or minus 5%, equipped with sensor + solenoid valve switch, the duplication of plus or minus 2%.Pneumatic torque wrench for its small volume, light weight, large power output of unit weight, can achieve high torque output, reaction force is small, small environmental pollution, low cost advantages, widely used in aerospace, mining, petrochemical, railway, building, heavy vehicle assembly maintenance, heavy equipment loading and unloading etc many fields, especially in production assembly line has been widely used, especially need large torque of the occasion.

Classify

Air wrench generally fall into two kinds, one kind is routine is the very common impact wrench, one kind is the pulse pneumatic wrench, the difference between the two is that the former can not set the torque, while the latter can be.Pneumatic torque wrench is belong to the latter
