Abstract

In order to improve the micro-high-speed centrifugal pump cavitation performance, to understand its internal cavitation characteristics. The internal flow field of the centrifugal pump model established by UG was simulated by CFX software. The performance of the centrifugal pump in different speed, flow and different inlet pressure conditions for performance analysis.The numerical results show that: The smaller the centrifugal pump speed, the smaller the head and efficiency. Impeller flow and the blade surface pressure along the inlet to the direction of the export gradually increased. The overall pressure loads distribution of the impeller increases with the increase of the rotational speed. The vacuoles first appeared at the impeller inlet and the blade suction surface. The smaller the speed, the smaller the amount of vacuoles produced. Overall, the more the speed away from the design speed, the worse the performance of centrifugal pumps and the impeller blade profile must be redesigned.
