Abstract

The article presents a promising non-contact face seal of the rotor of a dynamic machine. The principle of pulse balancing of the movable sealing ring is applied in the seal design. The design of the test equipment and seal samples, which were used to conduct comprehensive investigations of the seal in the operating range of speeds and pressures, are considerated. The analysis of the experimentally obtained data of the barrier gas flow rate parameters and pressure changes in the working gap of the seal is carried out. A comparison of the traditional physical model of the working process of leaking pulse seals with the results of the research is performed. Identified and analyzed the fundamental differences of working processes of the traditional leaking and considered non-leaking pulse seals. A model of the physical process is developed and recommendations for the creation of a mathematical model of the gas barrier pulse seal are formulated.
