Abstract EN
The model pump is a high-speed, high-power pump designed to achieve rapid mine flooding rescue.
This study conducted experiments to investigate pump performance curves, including head, efficiency, and power for the following six different rotation speeds: 3000, 3600, 4200, 4800, 5400, and 6000 rpm.
Then, the numerical simulation method based on computational fluid dynamics commercial code Ansys was used to present the internal flow of the pump for the six different rotation speeds through steady and unsteady analyses.
Results show that the numerical results agree well with experimental data.
The designs of outlet and inlet angles of the impeller match each other well at high rotation speeds.
The pressure pulsation coefficient Cp in the impeller and the diffuser channel remain constant at the same monitor point under different rotation speed conditions.
The varying trend of the pressure-augmented coefficient ΔP indicates that, with the increase in rotation speed, the effect on pressure rise induced by the back part of the impeller channel is more evident than that by the front part.
Also, the main frequency components of ΔP are concentrated on the region with low frequency.
Moreover, the rotation speed has no significant effect on ΔP in the diffuser region.
This study provides effective guidance and valuable reference for the design of high-speed, high-power pumps.
