| Abstract: | In this paper, based on the work mechanism of the flow pump, gas ingestion and failure of helical seal are fully explained. Moreover, a new type of combined helical seal is put forward. Analytical result indicates: at higher Speed, the combined helical seal is prior to the single helical seal, and inferior to the labyrinth helical - seal, which will be adaptable to engineering application. |
