These seals will have minimal leakage while maintaining increased operating parameters. This approach should ensure a reduction in operating costs of devices that use these seals, while simultaneously increasing energy efficiency and environmental safety of their operation popup.description2  Non-contact dry gas seals are quite widely used for sealing centrifugal machines such as centrifugal compressors, turbines, turbofans, turbojet engines, and chemical pumps when used as a lubricating layer in the gap of various gas mediums. They are gradually replacing traditional liquid seal systems in many turbomachines. Deep-groove impulse seals have a different principle of maintaining a gap between the faces of the rings than micro-groove mechanical seals. So, during shaft rotation, the compression leads the cavities to be periodically supplied by gas at a higher pressure gathered by the feeders. Therefore, there is an impulse feeding of the cavities and an increase in the opening force in the gap of the impulse seal. The following tasks are solved in this project: calculation analysis of gasdynamics and dynamics of the traditional design of the face impulse seal and calculation analysis of thermogasdynamics, deformations and dynamics of the buffer face impulse seal Product Description popup.authors Hudkov Serhii M.
