Description

Technical Field

[0001] This patent relates to the field of water pump technology, specifically an anti-vortex rectifying device at the water inlet end of a water pump. Background Art

[0002] The water supply system of the water flow device consists of water storage equipment, water pump station, pipeline system, standard instrument and pipeline of the meter to be tested. When the water depth of the water tank (pool) is not enough, a vortex is generated at the inlet of the water pump, resulting in poor stability of the water flow. The main reason is that the flow field of the water pump suction port in the water tank (pool) is chaotic, the flow velocity is unevenly distributed, and a vortex is generated. The closer to the center of the vortex, the greater the flow velocity, the smaller the static pressure, and the greater the amount of gas dissolved in the water. The depression in the center of the vortex increases the amount of air entering and reduces the water inlet cross-sectional area of ​​the water pump inlet, resulting in unstable water flow in the pipeline. Therefore, the repeatability of the calibrated flow meter is poor and the measurement error is large. At the same time, the vortex causes cavitation in the water pump, which reduces the operating performance of the water pump. The current water pump uses a baffle in the water tank (pool) to eliminate the vortex. At this time, the impeller of the water pump runs idle, causing the water pump to have cavitation problems.
