十年来液压传动与控制的传统应用领域变化不大。但由于电控伺服元件(伺服电动机和电动缸)的发展,并实际应用到机床工作台传动和小型火炮瞄准系统中,出现电液伺服系统被取代的趋势。但在其它领域,液压技术,特别是结合微电子技术,却仍具有强大的生命力和向其它应用领域的渗透力。液压技术在“开源”工作中的应用由于石油危机的出现,西方工业大国除大力研究高含水油、无管连接和能量回收等节油和节功率措施外,同时,在利用日光、风力、波浪等间接能源方面作了不少“开源”工作,也取得初步成果。
The traditional applications of hydraulic transmission and control have not changed much in the past decade. However, due to the development of electronically controlled servo elements (servo motors and electric cylinders) and their application to machine tool table drives and small artillery aiming systems, the trend of electro-hydraulic servo systems has been replaced. However, in other fields, hydraulic technology, especially combined with microelectronic technology, still has strong vitality and infiltration into other fields of application. Hydraulic Technology in “Open Source” Work Due to the oil crisis, the western industrial powers, in addition to vigorously studying oil-saving and power-saving measures such as high water-cut oil, pipe-less connection and energy recovery, Many indirect energy sources have done a lot of “open source” work and have also achieved initial results.
