Impeller modifications can be made to adjust the performance of the pump to some degree. Overfilling of centrifugal pumps should be done after a cut down to bring the blade tips thickness at the new outside diameter back to their original dimension. This prevents losses by not allowing slip ...
The present study aims to describe wear characteristics of a centrifugal pump that transports the mixture of water and solid particles. An experimental work is conducted to reveal patterns of wear of the hydraulic components. The computational fluid dynamics technique and the discrete element method ar...
Rotor suspension characteristics of magnetically levitated centrifugal pump under passive control is investigated by numerical simulation. Numerical models of the studied system are built, including a bearingless permanent magnetic slice motor (BPMSM) and a centrifugal pump. Authenticity of the numerical ...
aThe present research focuses on just one such fluid-structure interaction problem, namely, the role played by fluid forces in determining the rotordynamic stability and characteristics of a centrifugal pump 礼物研究焦点在一个这样流体结构互作用问题,即,可变的力量扮演的角色在确定一个离心泵的rotordynamic稳...
In very low specific speed range (n_(s) < 0.25), the efficiency of the centrifugal pump designed by the conventional method becomes remarkably low. Therefore, positive-displacement pumps have been widely used for long. However, the positive-displacement pumps remain associated with problems suc...
The demand for a centrifugal pump with open impellers for conveying dense fine particles in solid-liquid two-phase flow has increased significantly in actual engineering. The wear of dense fine parti...
1. 1.1. A multistage centrifugal pump is an energy device that connects in series two or more impellers with the same function. In the fluid-passage structure, the medium at this stage is connected...

Wu et al. [7] used experimental method to study the cavitation characteristics of centrifugal pump at the rapid start-up period, and the results showed that the head characteristics had obvious transient effect at the initial stage of start-up. Wang et al. [8] establish an analytical ...
On one hand, this is because with the rotation of the impeller, the liquid phase with greater density experienced a larger centrifugal force and moved to the impeller shroud, resulting in gas accumulation near the impeller hub. On the other hand, due to the existence of a pressure difference...
