Do you also know the single hammer structure and twin hammer structure of air ipact wrench, but you don't know exactly what they are, and you don't know where they are used and what scenarios they are used in, please take a look below
Twin hammer structure

The pneumatic impact wrench is to use the air flow of compressed air to push the blades, the blades rotate to drive the percussion block, the percussion block keeps knocking on the central shaft to do work and generate power to form a cyclic rotary movement, the driving side links the sleeve to tighten or disassemble the bolts, the twin hammer structure striking the block in the process of work, the two hammer blocks alternately hit each other, which will provide a higher strike rate and produce a continuous and stable torque output, which is suitable for places that require continuous high torque output, (rongpeng R901 torque reaches 1356N.M), This high torque is suitable for tightening or disassembling large bolts, such as the maintenance of large automobile tires and industrial equipment. The structure of the twin hammer structure is also more complex, and there are more parts involved inside(For example, rongpeng R901 and RP7488 are twin hammer structures).

Single-hammer structure
The hammer block of the single hammer structure is mounted on the rotor, and as the rotor rotates, the hammer block will rotate at high speed and hit the striking block inside the air wrench, and each impact will generate a torque, which is transmitted to the bolt or nut through the output shaft of the air wrench. The power output of the single-hammer wind wrench is concentrated on a single blow, and the torque is instantly higher, but the overall torque is not as good as the twin-hammer structure, (NPK NW-1200B torque reaches 700N·m), and every time the rotor rotates to a specific position, the hammer block will contact with the hammer block and produce a blow, so the torque output of the single-hammer structure is unstable. It is suitable for scenarios that need to complete tasks quickly, with a low frequency of blows, and is suitable for quick locking or disassembling bolts, such as disassembling and assembling small screws of automobile engine structure,Screw assembly of small car tires.

Rongpeng has many single hammer structure and twin hammer structure air wrench products for you to choose.
