The role of the pneumatic system, what are the main parts of the pneumatic system?

The role of pneumatic system Pneumatic technology is a professional technology that uses compressed air as a medium to drive and control machinery. Because it has the advantages of energy saving, pollution-free, high efficiency, low cost, safety and reliability, and simple structure, it is widely used in various machinery and production lines. In the past, pneumatic systems and their components on production lines such as automobiles and tractors were designed, manufactured and maintained by each factory. What are the main parts of a pneumatic system? The pneumatic circuit is used to drive mechanical devices for various purposes. Its three most important control contents are: the size of the force, the direction of the force and the speed of movement. Various types of cylinders connected to production devices rely on pressure control valves, directional control valves and flow control valves to control three contents respectively, namely: pressure control valve - control the size of pneumatic output force directional control valve - - Control the movement direction of the cylinder Speed ​​control valve - Control the movement speed of the cylinder A pneumatic system usually includes: Air source equipment: including air compressor, air tank Air source processing components: including aftercooler, filter, dryer and drainage Pressure control valves: including booster valves, pressure reducing valves, safety valves, sequence valves, pressure proportional valves, vacuum generator lubrication components: oil mist, centralized lubrication components Directional control valves: including electromagnetic reversing valves, air-controlled changers Directional valve, manually controlled reversing valve, machine-controlled reversing valve, one-way valve, shuttle valve, various sensors: including magnetic switches, limit switches, pressure switches, pneumatic sensors. Flow control valves: including speed control valves, buffer valves, Quick exhaust valve pneumatic actuators: cylinders, swing cylinders, air motors, air claws, vacuum suction cups, other auxiliary components: mufflers, joints and air pipes, hydraulic buffers, gas-liquid converters, pneumatic technology and other transmission and control methods (such as Compared with mechanical method, electrical method, electronic method, hydraulic method), the advantages and disadvantages are as follows. Advantages of pneumatic technology: 1. The pneumatic device has a simple structure, is lightweight, and is easy to install and maintain. The pressure level is low, so it is safe to use. 2. The working medium is inexhaustible air, and the air itself costs nothing. The exhaust treatment is simple, does not pollute the environment, and has low cost. 3. It is very easy to adjust the output force and working speed. The operating speed of the cylinder is generally 50~500mm/s, which is faster than the operating speed of hydraulic and electrical methods. 4. High reliability and long service life. The effective number of operations of electrical components is about one million times, while the life of SMC's general solenoid valves is more than 30 million times, and the life of small valves is more than 200 million times. 5. Utilize the compressibility of air to store energy and achieve centralized air supply. Energy can be released in short bursts to obtain high-speed response during intermittent exercise. Buffering is possible. It has strong adaptability to impact loads and overloads. Under certain conditions, pneumatic devices can be made to have self-retaining capabilities. 6. Full pneumatic control has the ability to be fireproof, explosion-proof and moisture-proof. Compared with the hydraulic method, the pneumatic method can be used in high temperature situations. 7. Due to the small air flow loss, compressed air can be supplied centrally and transported over long distances. Disadvantages of pneumatic technology: 1. Since air is compressible, the operating speed of the cylinder is easily affected by changes in load. This defect can be overcome by using gas-liquid linkage. 2. When the cylinder moves at low speed, because friction accounts for a larger proportion of thrust, the low-speed stability of the cylinder is not as good as that of the hydraulic cylinder. 3. Although the output force of the cylinder can meet the work requirements in many applications, its output force is smaller than that of the hydraulic cylinder. The above is the function of the pneumatic system. What are the main parts of the pneumatic system?
