Advantages and disadvantages of pneumatic systems

Advantage:

Simple structure, convenient maintenance, low cost, fast investment recovery. Good adaptability to working environment; can work reliably in environments with wide temperature range, high humidity, dust, vibration, etc.; a slight leakage will not pollute the environment, and no fire and explosion Dangerous and safe to use; long working life, solenoid valve life can reach 30-50 million times, cylinder life can reach 2000-6000km; actuator output speed is high, linear motion can reach 15m/s; overload protection capability, actuator It will stop automatically when overloaded, and there is no danger of damage, and it will remain motionless under the load when the power is not enough.

Disadvantages:

Due to the compressibility of air, the stability of the moving speed of the working parts is poor; the working pressure is low, and the output thrust of the pneumatic actuator is smaller than that of the hydraulic transmission; the speed of long-distance signal transmission is slow, and the air pressure signal transmission is not suitable for high-speed transmission complex circuits; Because the working pressure is low and the structure size should not be too large, the output force is small, usually not more than 10-40kN.
