Abstract

The invention relates to an embedded sealing ring, in particular to a destressing system and method for an end face sealing static ring of a liquid rocket engine. The system and the method are used for overcoming the defect that according to an existing destressing method for the end face sealing static ring of the liquid rocket engine, the residual stress of the end face sealing static ring cannot be effectively reduced through optimization of a cutting tool and cutting parameters, optimization of a clamping position and a clamping tool and optimization of press-fitting equipment and press-fitting parameters. The destressing system for the end face sealing static ring of the liquid rocket engine comprises an upper computer, a master controller, a high-temperature box, a low-temperature box, an automatic feeding and sorting device, an automatic detection device, a to-be-treated product turnover vehicle and a treated product turnover vehicle, the automation degree of the system is improved, the labor intensity of personnel is reduced, and the real-time monitoring of the destressing process is realized. Meanwhile, the invention further provides the destressing method suitable for the end face sealing static ring of the liquid rocket engine.

Description

technical field [0001] The invention relates to a mosaic sealing ring, in particular to a stress relief system and method for a liquid rocket engine end face sealing static ring. Background technique [0002] At present, the static ring of the liquid rocket engine end face seal mostly adopts a mosaic seal ring structure, which usually uses graphite material as the non-metallic seal ring piece, and at the same time uses metal materials such as S-07 and 4J31 as the metal ring seat. The force generated by radial deformation during interference fit makes the non-metallic sealing ring and the metal ring seat tightly combined. The inlaid sealing ring structure can not only ensure good centering, but also can transmit torque reliably and effectively, meeting the high-reliability requirements of sealing under high-frequency shock and vibration. However, due to the particularity of the structure of the mosaic seal ring, internal residual stress must be generated by machining during ...
