A, pneumatic tools use and maintenance
Broadly speaking, pneumatic tools is mainly using compressed air pneumatic motor and the external output energy work a tool, according to the basic way of working can be divided into: 1) rotary (eccentric vane) can move 2) reciprocating (volumetric piston) general pneumatic tools mainly by power output, homework form into parts, exhaust road, operation and control section, open to stop such main part, tool shell of pneumatic tools operation must also have energy supply, air filtration and pressure adjusting parts and tools accessories etc.
1, power output part: it is the main component of pneumatic tools, pneumatic motor and power output gear, it depends on a high pressure of compressed air blowing motor and motor rotor rotating blades rotating output, and through the whole transformation driving gear parts movement. According to whether the stator and rotor, pneumatic horse with pneumatic motor and motor can be divided into one, by eccentric motor, the quantity can be divided into a single, dual porosity motor and motor into stomatal into stomatal motor, etc. Whatever the form of pneumatic motor, all depend on compressed air blowing motor rotor blades, motor drive in high speed rotating blades, time and stator wall friction, it is the most common vulnerability in motor parts, thus it to the compressed air quality and compressed air molecules containing lubricant is high,
2, operation forms into parts: it is the main motor output will make corresponding rotation transformation. In the car industry, because the way with thread connection, most is the rotary motion, certainly also have beeline reciprocating movement. For different types of pneumatic tools, assignment transformation mainly divided into the mechanical part of the clutch and planetary gear set, friction chip clutch and planetary gear set, hydraulic oil cylinder, torsion bar and hammer block group, etc. Above all with rotating parts for important components, which determines the pneumatic tools, tighten the torsion size precision, tighten when speed, because it is an important parameter of the clutch, pressure or torque, so it's components is susceptible to damage,
3 and exhaust road section: obviously, exhaust part is the way out of compressed air passage, safeguard the normal movement of motor energy supply systems,
4, open and stop control parts, namely, the pneumatic switch which usually, because of its time and operators and external objects, and direct contact with the engineering plastics, appear easily damaged,
5, energy supply parts: compressed air compressor is mainly to compress air after the formation of compressed air pipes to the related gas and electricity, pulsing.
6, air filtration and pressure adjusting parts: due to the compressed air is usually made by the seamless steel pipelines, in the long-term use of, the inside of the moisture content, compressed air and dust will continue to form. If such a compressed air does not undertake any treatment, directly into pneumatic motor, it will cause motor life shortens greatly, thus causing the output power tools, and unstable, easy cause damage to the component such as motor, this series of pipes in the compressed air to pneumatic tools, compressed air filter, must set adjuster, pneumatic press for a the assignment. Pneumatic press mainly by the barometer, a filter, oil mist, the regulator components, including built-in filter cores, in use for a period of time after cleaning, maintenance periodically to replace,
7 and tool accessories: here's tool accessories refers installed in pneumatic tools on direct contact with the workpiece directly, pneumatic tools for the mission press pieces. Pneumatic press mainly by the barometer, a filter, oil mist, the regulator components, including built-in filter cores, in use for a period of time after cleaning, maintenance periodically to replace, Such a compressed air no processing, directly into pneumatic motor, it will cause the motor life shortens greatly, thus causing the output power tools, and unstable, easy cause damage to the component such as motor, this series of pipes in the compressed air to pneumatic tools, compressed air filter, must set includes all kinds of pneumatic device, adjust lever, conversion, and socket connector, electroplating, etc.
The foregoing section interdependence and interaction between restriction, can't exist alone this alone.
Second, pneumatic tools installation system
Air source (air compressors or press room), the oil-water separator - 3/8 "(1/2") fast connection - 3/8 "(1/2") over - 3/8 "(1/2") quick connectors, pneumatic tools.
Third, pneumatic tools operation
1, gas supply
(1) with 90PSI (6.2 Bar) clean, dry air supply tools. High pressure can quickly reduce tool life.
(2) using tools chart with the proper size of components, tube and hose connection tools.
(3) if the use of air pressure regulator, air pressure setting in 0.62 MPA pressure output.
Step 2,
(1) will be connected to the air line pneumatic tool.
(2) set good air pressure.
(3) air line must set air, if air lubricating oil device unqualified or device, shall give below the tools for routine maintenance:
A continuous work after 3 to 4 hours, tools and air, into separate from the drip drip 7-8 high-purity light oil (low viscosity), then open air links trachea, will blow into oil cylinder. Conditional users and working intensity and Suggestions in the air filled with small injector double-quick.
B. usually 30-40 days need to air compressor and oil-water separator drain, periodically to ensure impurities, maintenance, air clean and the tool into dry.
Four, pneumatic tools use advantages:
1 to obtain, and air pressure is low, the air can be used on pipeline, no recovery
2 the viscous gas flow resistance, low losses, facilitates concentration gas and long-distance transmission
3 pneumatic actuators movement speed is high
4 pneumatic system for environment adaptiveness, can be in a wide range of temperature, moisture and dust under the environment of the reliable work, slightly discharge not environmental pollution, no fire and explosion danger, the use of security
5 simple structure, easy maintenance, low cost
Pneumatic components and long service life
7. Pneumatic components of hydraulic, executive output than exercise faster, adaptable, but in YiRan, explosive and heavy, moisture, shock in the bad environment, no pollution, long working life, simple structure, easy maintenance, low price
Pneumatic series:
1 pneumatic generator - - - - - the air compressor
2 pneumatic actuators
3 pneumatic control components - - - - - used to control the working medium pressure, flow and flow to complete the components of the motion law of components, such as pressure, flow direction and control and various kinds of logic components etc
4 sensor and conversion components will be charged parameters and become pressure signal detection of qigong sensor and signal and gas electro-hydraulic signal conversion of each component
5 pneumatic auxiliary parts - - - - - - including air purification, components, components, connections and lubrication elements such as sound
