深海液压动力源发展现状及关键技术

The development status and key techniques of deep-sea hydraulic power source

通过对电力、气压、液压深海动力源进行比较,重点论述了深海液压动力源的两种类型:油压驱动和水压驱动,概括了各自的特点及应用领域。介绍了深海驱动电机的结构形式及一种直浸式深海直流无刷电机的结构实例。液压源是深海动力源的主要部件之一,分别从油压和水压两方面介绍了其国内外发展概况。油压驱动主要以闭式集成液压动力源为例,并介绍了液容、液感两种储存压力能的驱动方式。海水液压驱动由于其节能、不燃烧、无污染等特点,广泛应用于海洋领域。最后,分别就油压和水压驱动两方面总结了深海液压动力源研究的几个关键技术问题。

It lays great emphasis on two types of deep-sea hydraulic power source which are oil hydraulic driving and water hydraulic driving by comparing several deep-sea power sources of electric driving, pressure driving and hydraulic driving. Then it summarizes the characteristics and application of the two types of hydraulic power source. It also introduces the construction of the deep-sea motor and a prototype of Direct Immersion Motor. Hydraulic source is one of the main parts of deep-sea power source. The writer introduces the development situation of oil hydraulic and sea-water hydraulic respectively at home and abroad. For oil hydraulic drive, it takes a closed integration hydraulic power source as an example and introduces the deep-sea liquid-capacity nonstop and deep-sea liquid-sensible nonstop hydraulic power source. Sea-water hydraulic drive is used in sea field widely because of the characteristics of energy-saving, non-combustion, on-pollution and so on. In the end, it concludes several key technical matters of deep-sea hydraulic power research in the oil hydraulic drive and the sea-water hydraulic drive.
