一、概述机械产品都普遍存在泄漏问题,由于其涉及面广,所以又是一个综合性问题。其中密封技术是防漏的重要技术,所以长期以来密封问题被机械行业中的技术人员高度重视,并从各个方面开展试验研究工作。设备漏油是不可忽视的。据有关资料介绍,在美国如果液压设备能消除漏油,则每年可节油一亿加仑(约合34万吨),另外加上污染清理和油箱充油等费用,则每年可节约总费用将达数千万美元。我国机械设备漏油现象非常严重,如重庆嘉陵机器厂815车间(发动机车
First, an overview Mechanical products are generally leakage problems, because of its wide range of involved, so it is a comprehensive issue. Sealing technology is an important leak-proof technology, so the sealing problem has long been the mechanical industry, the technical staff attach great importance to, and from all aspects of experimental research. Equipment leakage can not be ignored. According to relevant information, in the United States, if the hydraulic equipment can eliminate oil spills, it can save 100 million gallons (about 340,000 tons) annually, and the total annual cost savings will be saved when pollution and oil tank filling are added Tens of millions of dollars. The phenomenon of oil spills in China’s machinery and equipment is very serious, such as Chongqing Jialing Machinery Factory 815 workshop (engine car
