2012年1月18日 · It is a common misconception in the U.S. pump industry that the function of the volute is that of a diffuser: to convert velocity into pressure. I have recently read and heard …

2011年12月17日 · Impact of the Volute. The performance of the volute has a significant impact on the overall stage performance. For simple stages with an impeller and volute combination, the …

2024年12月19日 · A multistage pump is a type of rotodynamic pump, meaning it uses rotating impellers to impart energy to the fluid it is pumping. What differentiates multistage pumps from …

2024年5月28日 · As the impeller turns, water is pushed from the center outward along the edge of vanes, which increases pressure. The high-pressure water is released from the ends of the …

2022年3月14日 · Please keep in mind my comments are general and the magnitude and veracity of the prescribed effects depend on the pump design, specific speed, energy levels and …

2021年1月20日 · Volute: A Critical Component. The pump volute earns its name due to the spiral shape casing surrounding the impeller. The volute is the often forgotten, but nevertheless still …

2022年1月3日 · The pump BEP is normally where these two “curves” intersect (in theory, these look more like straight lines than curves). Designing the impeller and casing to match each …

2014年1月22日 · The double-volute design (see Figure 1.3.3.2) is typically used to reduce shaft deflections and bearing loads to permit the use of a smaller shaft and bearing sizes or to …

2022年2月4日 · For an expanding volute pump where the impeller centerline is offset from the casing centerline (i.e., noncongruent), the clearance between the outer diameter (OD) of the …

2024年9月18日 · Typical mitigation strategies for high radial thrust include changing the discharge collector style (i.e., from a single volute to a double [dual] volute), trimming impellers to meet …
