机械密封是现代密封技术发展的一个重要组成部分,由于其性能先进、密封可靠、寿命长,对提高设备运行稳定性、防止泄漏起到重要作用,已广泛用于石油、化工、冶金等行业。 由于国内在机械密封的研制、开发、应用方面起步较晚,无论从产品的结构、品种、性能及适用工况条件,辅助系统的应用等方面均与国外存在较大的差距。自八十年代以来,我国从国外一些发达国家引进了许多技术先进的大型成套装置,这些装置的引进不仅促进了我国大型成套装置的技术水平,也带动了与之相关的包括机械密封在内的基础件的发展。促进了我国机械基础件的技术水平。就国内目前机械密封的现状来看,尽管已有较大的发
Mechanical seal is an important part of the development of modern sealing technology. Because of its advanced performance, reliable sealing and long service life, mechanical seal plays an important role in improving equipment operation stability and preventing leakage. It has been widely used in petroleum, chemical industry and metallurgy industries. As the development, application and development of mechanical seals in China started relatively late, there is a big gap with foreign countries in terms of product structure, variety, performance, applicable working conditions and the application of auxiliary systems. Since the 1980s, China has introduced a large number of large and complete sets of state-of-the-art devices from some developed countries abroad. The introduction of these devices has not only promoted the technological level of large-scale complete sets of devices in China, but has also led to the related issues including mechanical seals The development of basic parts. Promote the technical level of China’s mechanical parts. On the current status of mechanical seals in the country, despite the larger hair
