德國FESTO氣缸zui大的特征介紹,費斯托氣缸

德國FESTO氣缸的輸出力與缸徑的平方成正比；而電缸的輸出力與三個因素有關，缸徑、電機的功率和絲桿的螺距，缸徑及功率越大、螺距越小則輸出力越大。一個缸徑為50mm的氣缸，理論上的輸出力可達2000N，對于同樣缸徑的電缸，雖然不同公司的產品各有差異，但是基本上都不超過1000N。顯而易見，在輸出力方面氣缸更具優勢。 （3）適應性強。氣缸能夠在高溫和低溫環境中正常工作且具有防塵、防水能力，可適應各種惡劣的環境。而電缸由于具有大量電氣部件的緣故，對環境的要求較高，適應性較差。 電缸的優勢主要體現在以下3個方面： （1）系統構成非常簡單。由于電機通常與缸體集成在一起，再加上控制器與電纜，電缸的整個系統就是由這三部分組成的，簡單而緊湊。 （2）停止的位置數多且控制精度高。一般電缸有低端與之分，低端產品的停止位置有3、5、16、64個等，根據公司不同而有所變化；產品則更是可以達到幾百甚至上千個位置。在精度方面，電缸也具有的優勢，定位精度可達¡0.05mm，所以常常應用于電子、半導體等精密的行業。 （3）柔韌性強。毫無疑問，電缸的柔韌性遠遠強于氣缸。由于控制器可以與PLC直接進行連接，對電機的轉速、定位和正反轉都能夠實現控制，在一定程度上，電缸可以根據需要隨意進行運動；由于氣體的可壓縮性和運動時產生的慣性，即使換向閥與磁性開關之間配合地再好也不能做到氣缸的準確定位，柔韌性也就無從談起了。
德國FESTO氣缸zui大的優點是什么特征，德國FESTO氣缸在技術性能方面，本人認為電動和氣動各有所長，首先電動執行器的優勢主要包括： （1）結構緊湊，體積小巧。比起氣動執行器，電動執行器結構相對簡單，一個基本的電子系統包括執行器，三位置DPDT開關、熔斷器和一些電線，易于裝配。 （2）電動執行器的驅動源很靈活，一般車載電源即可滿足需要，而氣動執行器需要氣源和壓縮驅動裝置。 （3）電動執行器沒有“漏氣”的危險，可靠性高，而空氣的可壓縮性使得氣動執行器的穩定性稍差。 （4）不需要對各種氣動管線進行安裝和維護。 （5）可以無需動力即保持負載，而氣動執行器需要持續不斷的壓力供給。 （6）由于不需要額外的壓力裝置，電動執行器更加安靜。通常，如果氣動執行器在大負載的情況下，要加裝消音器。 （7）電動執行器在控制的精度方面更勝*。 （8）氣動裝置中的通常需要把電信號轉化為氣信號，然后再轉化為電信號，傳遞速度較慢，不宜用于元件級數過多的復雜回路。而氣缸的優勢則在于以下4個方面： （1）負載大，可以適應高力矩輸出的應用（不過，現在的電動執行器已經逐漸達到目前的氣動負載水平了）。 （2）動作迅速、反應快。 （3）工作環境適應性好，特別在易燃、易爆、多塵埃、強磁、輻射和振動等惡劣工作環境中，比液壓、電子、電氣控制更*。
