日本液压行业很重视液压系统的防漏与治漏。如果一年内把油液漏损量用油箱容量的多少倍来表示,并记为HFI,那么1970大约是HFI4,而到1981年下降到HFI1以下。之所以获得这样的效果,主要是采取了以下几条措施: 1、减少油管接头。系统漏油有30～40％是管接头漏出的。日本广泛采用集成回路和油 Japanese hydraulic industry attaches great importance to the hydraulic system of leakage and leakage. If the amount of oil leakage was expressed in terms of how many times the tank volume was reported in a year as HFI, then 1970 was about HFI4, and by 1981 it dropped below HFI1. The reason why such an effect is achieved, mainly taken the following measures: 1, to reduce the pipe fittings. System leakage 30 to 40% of the joints leaked. Japan widely used integrated circuit and oil
