Abstract

Abstract: When the magnetic liquid is applied to seal the shaft of hydraulic turbine, the sealing speed is low and unstable, and the characteristics of sealing liquid flow field have a great influence on the sealing failure. Based on the numerical calculation method, the flow field characteristics of the magnetic liquid seal are compared and verified by the experiments. The results show that the sealing pressure has little influence on the sealing liquid flow field, while the shaft speed has a great influence on the sealing liquid flow field. The conclusion provides theoretical guidance for the design of magnetic liquid sealing device for hydraulic turbine spindle.
