AI Technical Summary
The existing compressor shaft end labyrinth seal assembly cannot adjust the material shape and size of the labyrinth groove according to the fluid used for different purposes, resulting in poor sealing performance. Furthermore, the entire assembly needs to be replaced when the sealing ring plate and toothed plate are damaged, increasing the cost of use.
A multi-layered composite compressor shaft end labyrinth seal assembly is designed, including a housing, a rotating shaft, a sealing structure, and auxiliary components. Through the multi-layered composite sealing structure and limiting fixation, the adaptability and stability of the labyrinth seal are improved.
This improves the sealing effect and stability of the labyrinth sealing assembly, reduces the frequency of overall replacement due to damage to a single area, and lowers the cost of use.
