Stall phenomenon, a classical physical phenomenon which is located in the vaneless region
of a pump–turbine and accompanied by a complex vortex evolution process, is strongly …

Multi-stage centrifugal pumps with floating impellers provide a convenient means of
adjustment to meet diverse head requirements. These pumps utilize sealing gaskets to …

Pumps as turbines (PATs) are used in petroleum and chemical industries to recover high-
pressure residual energy. Multistage PATs allow for a wider energy recovery interval and …

In the process of oil production, wells containing gas can impact the efficiency of electric
submersible pump (ESP), potentially causing gas lock. This issue can lead to the loss of …

In this article, a typical mixed-flow pump was adopted as the research object to investigate
the influence of the inlet structure within the impeller on the performance and internal flow …

Studying the energy loss characteristics of the electrical submersible pump (ESP) under
stalling conditions is beneficial for reducing the global carbon emissions. By combining …

Mixed-flow pump is a general purpose hydraulic machinery in many fields of fluid transport
for its advantages of wide efficient operation flow rate range, but its operation stability is …

A bulb tubular pump unit is a horizontal tubular pump unit composed of a water pump and
bulb with an electric motor installed. Electric motors, transmission equipment, and bearings …

Mixed-flow pump is one of the most broadly applied sorts of power equipment in the field of
petrochemical and water conservancy. The effect of inlet prerotation on the energy …
