How to select the type of pneumatic wrench?
1, according to the scene of the trachea connector, choose the corresponding internal or external tooth quick connection, also useful trachea.2 、 according to the shape of the air pull joint, buy the air pipe.3, usually less than 3/4 are the same, the internal teeth, external teeth, trachea. The air head 1 inch bigger.
Pneumatic wrench is widely used in many industries, such as automotive repair, heavy equipment maintenance, product assembly (usually called "pulse tool" and designed for precise torque output), major construction projects, installation of steel wire Lo sets, and high torque output in any other part of the need.
Compressed air is the most common source of power, but there are also electric or hydraulic applications. In recent years, the use of batteries is also very popular.
Impact wrench (pneumatic wrench), also known as the ratchet wheel, hand and power tool assembly, is mainly a minimum consumption to provide high torque output tool. It allows a mass object to rotate at a constant speed through a constant power source, and then instantaneously hits the output shaft so that a relatively large torque output can be obtained.
There is no relevant national standards in China, each of the products are produced in accordance with their respective plant number, not comparable, you only for different manufacturers separate telephone or reading corresponding to the manufacturer's website, they will use specifications and types and specific methods indicate you have to buy the screws (usually less than 14 mm the choice of torque 312NM, 18 mm 540NM, 24 mm below 750NM, then the need to choose the air, it can hit 42 mm below the screw, locking force according to the specific setting you)You need the catalog selection, because the model is not uniform not listed, the driving head size is 1/4, 3/8', 1/2', 3/4 ", 1" models for matching.
