以下为实物拍摄 可以完替代进口气缸

气动元件的优点：　　

1、气动装置结构简单、轻便、安装维护简单。介质为空气，较之液压介质来说不易燃烧，故使用安全。 　　2、工作介质是取之不尽的空气、空气本身不花钱。排气处理简单，不污染环境，成本低。 　　

3、输出力以及工作速度的调节非常容易。气缸的动作速度一般小于1M/S，比液压和电气方式的动作速度快。 　　

4、可靠性高，使用寿命长。电器元件的有效动作次数约为百万次，而一般电磁阀的寿命大于3000万次，某些质量好的阀超过2亿次。 　　

5、利用空气的压缩性，可贮存能量，实现集中供气。可短时间释放能量，以获得间歇运动中的高速响应。可实现缓冲。对冲击负载和过负载有较强的适应能力。在一定条件下，可使气动装置有自保持能力。 　　6、全气动控制具有防火、防爆、防潮的能力。与液压方式相比，气动方式可在高温场合使用。 　　

7、由于空气流动损失小，压缩空气可集中供应，远距离输送。

 The advantages of pneumatic components:

1, the pneumatic device structure is simple, lightweight, easy to install and maintain.Medium is air, is difficult to burn than the hydraulic medium, it is safe to use.2, the working medium is the inexhaustible supply of air, the air itself is not money.Exhaust is simple, do not pollute the environment, and low cost.

3, the output power and operating speed of adjustment is very easy.Movement speed of the cylinder is generally less than 1M / S, than the action of hydraulic and electrical means faster.

4, high reliability and long service life.Effective functioning of the number of electrical components is about a million times, and the general life of the solenoid valve is greater than 30 million times, some good quality valves over 200 million times.

5, the use of air compression can be stored energy, centralized gas supply.A short-term release of energy in order to obtain high-speed intermittent movement response.Buffer can be realized.Shock load and overload on the strong adaptability.Under certain conditions, can have self-holding capacity of pneumatic devices.6, all pneumatic control a fire, explosion proof, moisture-proof ability.As compared with the hydraulic, pneumatic means can be used in high temperature applications.

7, due to air flow loss is small, the supply of compressed air can be concentrated, long-distance transport.
