本文讨论了波纹管机械密封的结构、设计和使用并阐述了这种密封的优点。最近几年由于工业及环境保护的要求,促进了密封技术的发展。出于安全、环境清洁和降低维护费用的需要和高温、高压和高速的应用,势必要求采用更好的密封方法。近年来设备制造厂和使用单位都感到老式的传统的填料密封已愈来愈不能适应现代密封的要求。这几年,用机械密封取代填料密封的趋势明显增长并且在不断努力研制性能优良的 This article discusses the structure, design, and use of bellows mechanical seals and explains the advantages of such seals. In recent years due to industrial and environmental protection requirements, and promote the development of sealing technology. For reasons of safety, environmental cleanliness and reduced maintenance costs and high temperature, high pressure and high speed applications, a better sealing method is bound to be required. In recent years, the conventional packing seals, both old-fashioned by the equipment manufacturer and the consumer, have increasingly failed to meet the requirements of modern seals. In recent years, the use of mechanical seals to replace the filler seal significantly increased the trend and continue to strive to develop excellent performance
