Encyclopedia of pneumatic tools knowledge

Pneumatic tools are the use of air compressor provided by the compressed air energy for the power source and work device, mainly the use of compressed air to drive the air motor and external output of kinetic energy work a tool, general pneumatic tools mainly by the power output part of the operation form conversion part, inlet and exhaust road part, operation start and stop control part, tool housing and other main parts. So what is the principle of pneumatic tools? What are the types of pneumatic tools, how to maintain pneumatic tools? Then this issue of the topic from the small series for you to explain the knowledge of pneumatic tools in detail.

What is a pneumatic tool?
Pneumatic tools are tools that use compressed air as power. This tool can be divided into manual and electric two categories. It uses compressed air as the power to drive the rotation or reciprocation of the workpiece by converting the pressure energy of the gas into kinetic energy. The application range of pneumatic tools is very wide, which is mainly used in metal processing, casting, forging, riveting, welding, machining and woodworking.

Classification of pneumatic tools
There are many classification methods for pneumatic tools, and the common ones are as follows:
1, according to the power source: pneumatic tools can be divided into two categories of hand tools and power tools. Power tools can be divided into AC motor type, DC motor type and rare earth permanent magnet motor type three;
2, according to the use of points: pneumatic tools can be divided into pneumatic tapping machine, pneumatic trimming machine, pneumatic punching machine, pneumatic drilling machine, pneumatic spot welding machine;
3, according to the mode of action: pneumatic tools can be divided into automatic and semi-automatic two kinds.
According to the structure, the pneumatic tool can be divided into three kinds: plunger type, piston type and scroll type.

Characteristics of pneumatic tools
(1) Safe and reliable operation.
2) Low power consumption.
(3) Can be used in a small space,
(4) Simple operation, easy to master.
(5) Long service life, low noise and pollution-free.
(6) With self-locking function to prevent misoperation.
(7) Can use a variety of different gases, such as: air, compressed air, gas, etc.
(8) The appearance of pneumatic tools can be designed into a variety of different shapes to adapt to the processing needs of different workpieces.

Maintenance of pneumatic tools
Tools should be regularly carried out safety checks, the specific items of inspection mainly include:
(a) The air supply hose and joint should be connected reliably, and no loose air leakage should be allowed: the intake valve should be well sealed, the switch should be flexible, and the entire air path should be sealed without air leakage.
(b) The gas supply pipeline should be in good condition, and should be replaced immediately if there are defects such as wear and aging, corrosion and local air leakage and bulking.
(c) Check the protective device, such as wear, cracks, bending and other phenomena should be replaced in time.
(d) Check whether the working parts are in good condition, and replace them immediately if there are cracks or defects.
(e) Check the speed and condition of the tool. Rotary tools should ensure that the tool rotates in a good balance state impact tools should ensure that its anti-loosening fastening device is always intact.
