Information

Advantages of pneumatic technology:

1. The adjustment of output force and working speed is very easy. The movement speed of the cylinder is generally 50~500mm/s, which is faster than the movement speed of hydraulic and electric methods.

2. Using the compressibility of air, it can store energy and realize centralized air supply. It can release energy in a short time to obtain high-speed response in intermittent exercise. Can be buffered. It has strong adaptability to shock load and overload. Under certain conditions, the pneumatic device can be self-retaining.

3. The pneumatic device has simple structure, light weight, and simple installation and maintenance. The pressure level is low, so it is safe to use.

4. The working medium is inexhaustible air, and the air itself does not cost money. The exhaust gas treatment is simple, does not pollute the environment, and has low cost.

5. High reliability and long service life. The effective number of actions of electrical components is about one million times, while the life of SMC's general solenoid valve is more than 30 million times, and that of small valves is more than 200 million times.

6. Due to the small air flow loss, compressed air can be supplied centrally and transported over long distances.

7. Full pneumatic control has the ability of fireproof, explosion-proof and moisture-proof. Compared with the hydraulic method, the pneumatic method can be used in high temperature situations.

Disadvantages of pneumatic technology:

1. When the cylinder moves at low speed, the low-speed stability of the cylinder is not as good as that of the hydraulic cylinder because the friction force accounts for a large proportion of the thrust.

2. Although the output force of the cylinder can meet the working requirements in many applications, its output force is smaller than that of the hydraulic cylinder.

3. Due to the compressibility of air, the movement speed of the cylinder is susceptible to changes in load. The gas-liquid linkage can overcome this shortcoming, and the cylinder speed is faster than hydraulic pressure.
