The difference between electric tools and pneumatic tools

Pneumatic tools are generally used as portable tools and require small and light weight. Therefore, this goal has been achieved by rationalizing the structure, shape, 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. 1. Work Ability (A) Both provide a variety of different working methods, such as: rotation, reciprocation, swing, impact, etc. (B) Speed ??adjustment and output power adjustment are simple. The operation of the air supply valve handle and the adjustment of the adjustment valve can be carried out very simply. (C) Pneumatic tools can provide more levels of choice in the speed range, from 100rpm to 70000rpm. (D) The output power is larger according to the ratio of weight to volume. In the case of the same output power, it is small and light compared to electric tools. (E) No heat and overload failure. Pneumatic tools are more suitable for long hours of work without heat, and even if the compressed air engine is overloaded, the tool simply stops rotating. Once the overload is removed, it will resume normal operation and has no effect on the tool, nor Any failure will occur. (F) In terms of reciprocating motion, pneumatic tools use piston movement, while electric tools are converted by cams. In contrast, pneumatic tools have more advantages. 2. Environmental adaptability (A) Strong water resistance. Although immersion is harmful to tools, it will not be as deadly as electric tools. And because there will be no electric sparks, even if it is used in a place where there is a danger of explosion, there is no possibility of ignition and explosion. It is more suitable for use in coal mines, oil fields and other positions. (B) Pneumatic tools can work in various bad or harsh environments, but must be well maintained (dust removal, water removal, fueling, 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. Economic (A) The initial investment of power tools is low, but the long-term energy consumption is high, and the cost of tool maintenance and replacement is also high. (B) The initial investment of pneumatic tools requires the establishment of air pressure pipeline equipment, but the long-term use of lower energy consumption and tool maintenance costs are lower. (C) The weight of electric tools is generally 3 to 4 times that of pneumatic tools, which is not suitable for long hours of work, and pneumatic tools can improve work efficiency.
