Since pneumatic tools are generally used as portable tools, they are required to be small and lightweight. Therefore, this purpose has been achieved through rationalization of structure and appearance, high-precision processing, strict material selection, and strict heat treatment. Therefore, it is easier to use and more powerful, and has many advantages that power tools do not have. Compared with power tools, it has the following advantages. I. Working ability (a). Both provide a variety of different working methods, such as: rotation, reciprocation, swing, impact, etc. (B) Simple speed adjustment and output power adjustment. The operation of the supply valve handle and adjustment of the regulating valve can be easily performed. (C). Pneumatic tools can provide more levels of choice in the speed range, from 100rpm to 70,000rpm. (D). The output power is greater than the weight-to-volume ratio. At the same output, it is smaller and lighter than a power tool. (E). No heat and overload failure. Pneumatic tools are more suitable for long-term work without heat generation, and even if the compressed air engine is overloaded, the tool simply stops rotating, and once the overload is removed, it resumes normal operation without affecting the tool and does not affect No failures will occur. (F). In terms of reciprocating motion, pneumatic tools use piston motion, while electric tools are converted by cams. In contrast, pneumatic tools have more advantages. 2. Environmental suitability (a). Strong water resistance. Although water immersion is harmful to the tool, it is not as fatal as the power tool. And because it does not generate electric sparks, even if it is used in places where there is an explosion danger, there is no possibility of ignition and explosion, and it is more suitable for use in posts such as coal mines and oil fields. (B). Pneumatic tools can work in a variety of bad or harsh environments, but they must be well maintained (dust removal, water removal, refueling, etc.). Pneumatic tools can use internal combustion engine air pumps, so they are more suitable for field work. Pneumatic tools can work for a long time and are suitable for large-scale production lines. 3. Economy (a). The initial investment of electric tools is low, but the long-term use of energy consumption is high, and the cost of tool repair and replacement is also high. (B). The initial investment of pneumatic tools requires the establishment of air pressure piping equipment, but long-term use has lower costs in terms of energy consumption and tool maintenance. (C). The weight of electric tools is generally 3 to 4 times that of pneumatic tools, which is not suitable for long-term work, but pneumatic tools can improve work efficiency.
