Flow mechanism and axial force distribution characteristics of multistage pump cavity

open access: yesScience Progress, 2022
The gap leakage between the impeller ring leads to the change of the pump cavity flow characteristics, resulting in the uneven pressure distribution of shroud, which causes the axial force of the cavity to change. In this paper, the flow in the front and

Comparison of Saddle-Shaped Region of Head-Flow Curve between Axial-Flow Pump and Its Corresponding Axial-Flow Pump Device

open access: yesShock and Vibration, 2021
In engineering, the highest operating head of the pumping station is usually controlled to be slightly lower than the lowest saddle bottom head of the axial-flow pump.

The design of axial shaftless pump [PDF]

open access: yesEPJ Web of Conferences, 2017
The axial shaftless pump with a rotary casing has been proposed. The pump is unique in its small space requirements and the ability to draw a liquid with a high content of impurities and fibers. Modern motor with an external commutation was used to propel the pump rotor. The pump can be used for both pumping of liquids and marine propulsion.

Study on Restraining Cavitation of Axial Piston Pump Based on Structure of Cylinder Block and Valve Plate Triangular Throttling Groove

open access: yesShock and Vibration, 2022
Raising the rotational speed is an effective way to improve the power density of axial piston pump, but high rotational speed tends to cause plunger cavity and valve plate throttling groove cavitation.

Optimal Design and Fish-Passing Performance Analysis of a Fish-Friendly Axial Flow Pump

open access: yesApplied Sciences, 2023
In this paper, the parameters of a prototype runner of an axial flow pump are optimized by using the immersion boundary–lattice Boltzmann numerical method based on a large-eddy simulation (LES-IB-LBM).

Erosion in Helico-Axial Pumps

open access: yesLubricants, 2023
With recent advancements in the petroleum industry, the need for multiphase pumps to transport multiphase products, such as the product of oil, water, and natural gas, arises along with their challenges. A helico-axial multiphase pump should be capable of converting fluid kinetic energy into pressure by avoiding gas–liquid separation and the gas ...

Axially symmetric fiber side pumping

open access: yesOptics Express, 2006
A method for axially symmetric fiber side pumping is proposed. The method is based on a coupling structure and a pump source that both utilize the axially symmetric geometry of a typical optical fiber. The coupling structure can be manufactured by adding material to and/or by removing material from the fiber. In principle, the method enables the launch
