Advantages of pneumatic components:  

1. Pneumatic device is simple in structure, light and easy to install and maintain.  The medium is air, which is not easy to burn compared with the hydraulic medium, so it is safe to use.  

2, the working medium is inexhaustible air, air itself does not cost money.  Exhaust treatment is simple, no pollution to the environment, low cost.  

3. It is very easy to adjust the output force and the working speed.  The speed of the cylinder is generally less than 1M/S, which is faster than the speed of the hydraulic and electrical modes.  

4, high reliability, long service life.  The service life of effective action of electrical components is about one million times, and the life of the general solenoid valve is more than 30 million times, some good quality valves more than 200 million times.  

5, air compressibility can store energy, to achieve centralized air supply.  The energy can be released in a short time to obtain a high speed response in intermittent motion.  It can be buffered.  Strong adaptability to impact load and overload.  Under certain conditions, the pneumatic device can be self-sustaining.  

6, full pneumatic control is with fireproof, explosion-proof, moisture-proof ability.  Compared with hydraulic mode, pneumatic mode can be used in high temperature occasions.  

7, because the air flow loss is small, compressed air can be centralized supply, long-distance transportation.


Advantages and disadvantages of pneumatic components

Disadvantages of pneumatic components  

1, because the air has compressibility, the speed of the cylinder is subject to changes in load.  This defect can be overcome by gas-liquid linkage.  

2. When the cylinder is moving at low speed, the low speed stability of the cylinder is not as good as that of the hydraulic cylinder due to the large proportion of friction in the thrust.  

3, although in many applications, the output force of the cylinder can meet the work requirements, but its output force is smaller than the hydraulic cylinder.
