摘要
分析了炼油装置高温油泵现有单端面波纹管密封存在的主要问题,开发出一种高温泵新型油膜润滑波纹管串联式机械密封,介绍了其结构特点和技术优势。工业应用结果表明:高温泵新型油膜润滑波纹管串联式机械密封使用寿命长、安全可靠、封油消耗量少,省去了冷却水系统,且运行维护费用低,经济效益显著,具有很高的推广价值。
The main issues of single bellow mechanical seals used on oil refining high temperature pumps were analysed and a new-type oil-lubricated non-contacting metal bellow mechanical seal was developed.The configurations and the technology advantages were introduced.The results of industrial application indicate that the new seal has series advantages such as long life,high safety and reliability,little consumption of barrier or buffer liquid,no waste of water and low maintenance cost,etc.
