Analyze the advantages and disadvantages of electric tools and pneumatic tools from three aspects

what is the difference between pneumatic tools and electric tools? The initial investment of electric tools is low, but the long-term use of energy consumption is high, and the cost of tool maintenance and replacement is also high. The advantage of pneumatic tools is that they can play their due role to work in various adverse or harsh environments, but they must also be well maintained

differences between electric tools and pneumatic tools

pneumatic tools are generally used as portable tools and require small and light weight. Therefore, this goal is achieved through rationalization of structure, shape, high-precision processing, strict material selection, strict heat treatment, etc. Therefore, it is more convenient to use and has greater power, and has many advantages that electric tools do not have. Compared with electric tools, it has the following advantages

I Working capacity

(a) both provide a variety of different working modes, such as rotation, reciprocating, swing, impact, etc

(b) speed adjustment and output power adjustment are simple. It is easy to operate the air supply valve handle and adjust the regulating valve

(c) pneumatic tools can provide more choices in the speed range, from 100RPM to 70000rpm

(d) the electronic tensile testing machine by weight is applicable to the stretching, peeling, deformation, tearing, heat sealing, bonding, puncture force, opening force, low-speed unwinding force of plastic film, composite material, soft packaging material, plastic hose, adhesive, adhesive tape, self-adhesive, medical patch, protective film, release paper, combination cover, metal foil, diaphragm, back plate material, non-woven fabric, rubber, paper fiber and other products The specific output power of the test volume is large, such as the stripping force. Under the same output power, it is small and light compared with electric tools

(E) no heating and overload fault. Pneumatic tools are more suitable for the maintenance of oil source of equipment working for a long time, without heating. Even if the compressed air engine is overloaded, the tool just stops rotating. Once the overload is removed, it will resume normal operation, without any impact on the tool and without any failure

(f) in terms of reciprocating motion, pneumatic tools use piston motion, while electric tools use cam conversion. In contrast, pneumatic tools have more advantages

II Environmental applicability

(a) strong water resistance. Although immersion in water is harmful to tools, it will not be as deadly as electric tools. And since no electric spark will be generated, even if it is used in places with explosion risk, it will not cause the possibility of ignition and explosion. It is more suitable for coal mines, oil fields and other posts

(b) pneumatic tools can work in various bad or harsh environments, but they must be well maintained (dust removal, water removal, refueling, etc.). Pneumatic tools can use internal combustion engine air pump, so they are more suitable for field work. Pneumatic tools can work for a long time and are suitable for large-scale production lines

III 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 maintenance and replacement is also high

(b) the initial investment of pneumatic tools requires the establishment of air pressure pipeline equipment, but the cost of long-term use is low in energy consumption and tool maintenance

(c) the weight of electric tools is generally 3~4 times that of pneumatic tools, which is not suitable for long-time work. Liuyanlong, Secretary General of China chemical and physical power supply industry association of pneumatics, said that tools can better improve work efficiency
