Fig. 2.4: Valveless pneumatic hammer | Pneumatic drive systems are found in all areas of industry and the crafts. These can perform rotary and linear movements. Linear movement with the aid of cylinders in particular is seen as a highly economical and rational application. The utility work is performed by dropping the pressure and changing the volume of the compressed air.
Pneumatic percussion machinery and tools (e.g., pneumatic hammers) are of great importance in this category. The energy in the compressed air is converted into kinetic energy for a moving piston. Vibrators and jolting devices belong to this category.
Pneumatic power is also used by a multitude of valves and slides, tools, adjustment devices, feed systems and vehicles. |
