有机工质透平是新能源开发和节能技术中的一个重要项目,密封问题是其研制应用的关键,它的工作条件十分复杂,密封机理至今仍未被人们充分认识。我们研究了密封的端面流体动力润滑理论,并研制了双端面型式的机械密封。 Organic refrigerant turbine is an important project in the development of new energy and energy-saving technologies. The sealing problem is the key to its development and application. Its working conditions are very complicated, and the sealing mechanism has not yet been fully recognized by people. We studied the theory of sealed end hydrodynamic lubrication and developed a double-ended version of the mechanical seal.
