石油化工泵的可靠性在很大程度上取决于广泛采用的机械密封。在石化企业中,输送的流体大多易燃、易爆、有毒。一旦机械密封失效泄漏,不仅污染环境,危害健康,还极易导致火灾、爆炸等重大事故,所以是个热点问题。本文对国内外机械密封新技术进行了较全面的阐述,从机械密封的结构、型式、种类、材料和浏控技术等方面介绍机械密封的发展水平和新进展。
The reliability of a petrochemical pump depends very much on the widely used mechanical seal. In petrochemical companies, most of the fluid delivered is flammable, explosive and toxic. Once the mechanical seal fails to leak, it not only pollutes the environment and endanger the health but also can easily lead to major accidents such as fire and explosion. Therefore, it is a hot issue. In this paper, the new technology of mechanical seal at home and abroad was comprehensively expounded. The development and new development of mechanical seal were introduced from the aspects of structure, type, type, material and navigation technology of mechanical seal.
