1.前言高水基流体或高含水量流体是液压驱动用的流体,其含水率为95％左右,一般简称为HWBF。在日本,本研究委员会称它为“高水基比流体”,而(财)机械振兴协会技术研究和(社)液压工业会的研究计划中则称为“高水基工作液”。实际上,简称“高水基流体”也是可以的。由于叫法难以统一,本文则采用简称的HWBF。 1979年,从欧美的通用、福特、奔驰等汽车制造厂在生产线的机床上,用HWBF作为工作液来代替油这一消息传出以后,在日本液压技术同行中间,对这种流体也表示出极大的关注。在这种情况下,本研究委员会考虑到当时 1. Introduction High-water-based fluids or high-water-content fluids are fluids that are driven hydraulically and have a moisture content of about 95%, commonly referred to as HWBF. In Japan, the research board called it “a high-water-based fluid,” and the research program of the Association for Technical Renovations and the Hydraulics Industries Society of China Machinery Association was called “high-water-based working fluid.” In fact, the abbreviation “high water-based fluid” is also possible. As the call is difficult to unify, this article uses the short HWBF. 1979, from the United States and Europe, GM, Ford, Mercedes-Benz and other car manufacturers in the production line of machine tools, with HWBF as a working fluid to replace the news of this oil came in the middle of Japan’s hydraulic technology counterparts, also expressed this fluid Great concern. In this case, the research committee considered the time
