Problems solved by technology

Because the diversion cone occupies a certain space under the trumpet tube, the water inlet section becomes smaller, there is a risk of insufficient suction flow of the water pump, and it will also cause vortex generation in other positions while eliminating the original vortex; and the strip vortex elimination plate Often only the vortex in a certain direction can be eliminated, and it is difficult to completely eliminate the vortex near the horn tube

Abstract

The invention relates to the field of pump station engineering, and in particular relates to a vortex-eliminating structure for a suction sump of a pump station. The vortex-eliminating structure for the suction sump of the pump station comprises a vortex-eliminating plate and a horn-shaped pipe, wherein a water pump water inlet pipe is connected to the top end of the horn-shaped pipe, a water inlet is formed in the bottom end of the horn-shaped pipe, the vortex-eliminating plate is horizontally arranged below the bottom end of the horn-shaped pipe, the cross section of the vortex-eliminating plate is X-shaped, and the vortex-eliminating plate is used for eliminating vortexes near the horn-shaped pipe. With the vortex-eliminating structure for the suction sump of the pump station, the vortex strips near the horn-shaped pipe can be effectively eliminated, so that the uniformity of the water flow entering a pump can be improved, and further, the operating efficiency and stability of the water pump can be improved.

Description

technical field [0001] The invention relates to the field of pumping station engineering, in particular to a vortex-eliminating structure of a pumping station inlet pool. Background technique [0002] The trumpet tube of the water inlet tank of the pump station is directly connected to the water inlet pipe of the water pump, which has a great influence on the flow state of the water pump inlet. There are often suction vortex, bottom vortex and side wall vortex near the trumpet tube. These are important factors affecting the water flow pattern of the pump, and also important factors affecting the efficiency and stable operation of the pump. In order to improve the flow state near the horn tube, scholars at home and abroad have added a diversion cone (conical frustum) or a strip-shaped vortex-eliminating plate under the horn tube. Because the diversion cone occupies a certain space under the trumpet tube, the water inlet section becomes smaller, there is a risk of insufficien...
