气动技术正经历一个与之并行的电子控制一体化的过程,但是对这种发展的宣传却少于对液压电子一体化的宣传。自从射流技术出现以来,在气动技术领域中从没有出现过如此令人兴奋的事。虽然气动没有因为液压电子一体化的出现而被忽视,但至今为止大家的注意力主要还是集中在液压电子技术上。这其中的一个原因可能是在美国电子液压控制最初是作为一种代替车辆用大功率液压阀的液—液先导阀的技术而开发的。另一个更基本的原因则是:液压技术采用不可压缩的流体(液体)作为能量传递介质,而气动却采用了可压缩的流体(气体)作介质。在历史上,这种差别使开环控制的液压系统比与之竞争的 Pneumatic technology is experiencing a parallel process of electronic control integration, but less publicity about such developments than hydraulic electronic integration. Ever since the advent of jet technology there have never been such exciting things in the field of pneumatic technology. Although the pneumatic is not due to the emergence of hydraulic and electronic integration has been neglected, but so far everyone’s attention is mainly focused on hydraulic electronics. One of the reasons for this may be that electrohydraulic control was originally developed in the United States as a liquid-liquid pilot valve replacement for high-power hydraulic valves for vehicles. Another more fundamental reason is that hydraulic technology uses an incompressible fluid (liquid) as the energy transfer medium while the pneumatic uses a compressible fluid (gas) as the medium. Historically, this difference has made open-loop control of hydraulic systems more competitive
