The pneumatic tooth works either on carbon dioxide, or in air, compressed by a special compressor. This feature makes it safe in operation and cheaper compared to the power tools. In addition, its power exceeds electrical analogs with smaller dimensions and mass, due to which, working with pneumatic tool is more efficient.

Pneumatic tool classification

There is a classification by which such equipment is divided into two categories: the first includes an industrial tool, to another - service. Industrial must work continuously, to complete wear. The service includes simpler equipment for car service and other small enterprises.

There is another way to classify, according to which professional tool can be divided into the following types:

• shock (pneumatic hammers, jackhammers, dowellers, etc.);
• shock-rotational (pneumocrats, wrench, perforators);
• rotational action (grinders, wrench, saws).

The advantages of pneumatics allowed to expand the range of instruments of the labor of such a principle of operation. Manufacturers have settled the release:

• pulmonary perforators;
• vacuum cleaners;
• needle brushes (for cleaning metal);
• Cyanok;
• buds;
• sandblasting pistols;
• airbrodes;
• cutting machines;
• hack and disk saws;
• vibrationovers;
• Kraspopult (paint-sprayers).

Advantages of pneumatic tools

1. You can use in rooms with an increased fire hazard.
2. The lack of electrical voltage makes the work safe.
3. It is used in the premises of any category of electrical safety (under conditions of high humidity and temperature), in conditions of strong air pollution.
4. The ratio of high power with weight and size of the pneumatic tool allows to reduce operator fatigue, increase the time of continuous operation.

Buy pneumatic tool is better because:

• it is easy to use (special training of the operator is not required);
• its resource exceeds this indicator of the power tool;
• the risk of obtaining mechanical injury is reduced: due to the large number of revolutions, the turbine "in the separation" will not go;
• the noise level during operation is reduced due to the dense fit of parts to each other;
• in some cases, the analogues of the tool of other types are absent (for example, at a pneumomol wall or a wrench that allows you to unscrew the coated rust nut or bolt);
• it does not fail due to voltage drops on the network or damage to the cable due to their absence;
• the risk of lesion of the operator to the current is excluded due to the lack of current-carrying parts;
• fewer parts in the design and the absence of plastic and rubber parts contributes to greater reliability:  this eliminates the concept of "overload" in relation to the tool of this type, as it is almost nothing to melted and burn;
• they can be performed during wet grinding or in the rain;
• the pneumatic wrench can be promoted by affected rust compounds that are not amenable to other tools.

All pneumatic tools have a greater power with less weight and volume. The absence of an electric motor is the main reason for this. The operator gets the ability to handle narrow, hard to reach for another tool. In addition, moving parts begin to work immediately after exposure to compressed air: the lack of inertia performing mechanisms facilitates work.
All parts of the mechanism (bearings, gears, rotors, spindles) are made of structural and alloyed varieties of steels, and the housing is made of aluminum alloys. The lack of ventilation holes (no need for air-cooled) does not allow dirt and dust into the middle. This reduces wear wear.
Disadvantages should also be mentioned.

1. Weak corrosion resistance due to a large amount of metal parts.
2. For work it is necessary to purchase a compressor and special drying filters for air dehydration. In addition, it is necessary to change the oil for pneumatic tool in a timely manner: this will reduce the wear of parts and improve heat removal.
3. Low efficiency of the general system: high tool efficiency is impossible without high energy costs for the compressor.

Scope of use of pneumatic tools

A set of pneumatic tool for auto repair shop may include: wrench, spray gun, needle brush. Car service enterprises more often than others use the advantages of pneumatics due to safety to work in a medium saturated with fuel vapor. Also found applications on industrial wrench assembly lines.

With high humidity, pneumatic equipment is indispensable. This makes it possible to use it at the enterprises of the communal sphere, in ship repair workshops and in construction. Factories and plants also willingly exploit such a tool: pneumatic presses, for example, are most effective. The cost-effectiveness of the pneumatics is also important: tools working on such a principle less consumes electricity or without it without it.

Recommendations for the acquisition and operation of pneumatic tools

1. It is necessary to determine the tasks to solve the pneumatic tool: the price of industrial equipment may differ from the service several times.
2. The compressor is acquired depending on how much air is necessary for the operation of the tool. For example, the press requires 250 liters of air, and the bobbing pistol is not more than 25 liters.
3. Industrial pneumatics can be manufactured by the manufacturer by individual order.
4. Before purchasing the pneumatics of the industrial class, it should be properly designed highways for supplying air to him: the flexible hoses are not recommended. Pipelines made of copper proven best of themselves.
5. Preferably a closed pipeline system: this will allow to align the pressure on all areas. If necessary - install additional receivers.
6. Trumpet pipes are installed at an angle of 2 degrees, which ensures the flow of the generated condensate. At the end of the system, drain cranes should be provided.
7. To reduce the amount of condensate, the highway for the supply of air is laid along the walls: there is more stable temperature there. Masting in the walls is not allowed.
8. Before starting the system, it is necessary to blow to remove garbage from pipes.
