It is shown that the dissipation characteristic of a centrifugal pump can be obtained from the normal characteristic of the same pump. Using the dissipation characteristic of the weaker of two pumps coupled in parallel and the normal characteristic of the larger of the two pumps, an expression ...
Operational Characteristics of a Centrifugal Pump - Normally, a centrifugal pump produces a relatively low pressure increase in the fluid. This pressure increase can be anywhere from several dozen to several hundred psid across a centrifugal pump with a single stage impeller. The term PSID (Pounds ...
Measurements of velocity have been obtained in a centrifugal pump in terms of angle-resolved values in the impeller passages, the volute, the inlet and exit ducts and are presented in absolute and relative frames. The pump comprised a radial flow impeller with four backswept blades and a single...
Experimental and numerical investigations have been carried out to study the behaviour of a centrifugal pump operating in direct mode or turbine mode. First of all, the complete characteristics (head, power, and efficiency) were measured experimentally using a specific test loop. The numerical data ...
The simulation calculation of multi-stage centrifugal pump is drawn using the SST k-ω turbulence model. and the influence of the streamlined anti-guide vane on the hydraulic performance is studied. The result shows that: Under various flow conditions, the head of the multistage centrifugal pump ...
Effect of particle size, particle size distribution, specific gravity, and solids concentration on centrifugal pump performance Experiments have been conducted to study the individual effect of particle size, particle size distribution, specific gravity and concentration of solids on the centrifugal pump pe...
However, very little is known about the magnitude of this noise source or its behaviour under changing conditions, such as fluid temperature. This paper presents a determination of the source characteristics at the vane passing frequency of a double-volute, single discharge centrifugal pump based on...
Despite the considerable efforts that have been devoted to the study of head-flow curve instability in single-stage centrifugal pumps with volute casing, the cause of such phenomenon is not sufficiently understood. In this study, we investigated the variation of hydraulic losses based on the......
摘要: Variations of the Characteristics of the Centrifugal Pump and Flow Conditions at the Outlet of the Impeller due to the Difference of the Size of the Volute Chamber 葛西 泰二郎 機械学會論文集 2(7), 235-244, 1936DOI: 10.1299/kikai1935.2.235 年份: 1936 ...
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...
