Abstract

The invention relates to the technical field of vortex suppression devices in water conservancy projects, in particular to a flow guiding and vortex suppressing device for a water inlet pool of a guide vane type pump station. The flow guiding and vortex suppressing device comprises a lower annular base, an upper annular base and a plurality of guide vanes arranged between the lower annular base and the upper annular base. The guide vanes are circumferentially arranged. By means of the flow guiding and vortex suppressing device, vortexes near an inlet of a water inlet pipe can be effectively suppressed, flow loss in the water inlet pool is lowered, the flowing uniformity in the water inlet pipe is improved, and the flow guiding and vortex suppressing device has the advantages of being simple in structure, convenient to mount and high in practicability.

Description

technical field

[0001] The invention relates to the technical field of vortex elimination devices in water conservancy projects, in particular to a flow guide and vortex elimination device for an inlet pool of a vane-type pumping station. Background technique

[0002] The pump station inlet pool is a hydraulic structure where the pump inlet pipe directly draws water. Its main function is to provide good water inlet conditions for the pump. When the water pump is running, the unreasonable design of the water inlet pool or the large flow rate often lead to problems such as uneven flow velocity distribution in the water inlet pipe and vortex in the pool. The vortex will cause the fluid to generate a circumferential velocity in the water inlet pipe, causing the inlet of the pump to have a pre-rotation, which will affect the operation stability of the pump system; and the vortex will also aggravate the pulsation of the water flow in the inlet pool, which will easily cause problem...
