The invention discloses a vertical pump eddy guiding suction device which comprises a suction body, eddy guiding blades, a guide bearing pedestal and a positioning column. The upper end of the suction body is communicated with a guide blade body, a water inlet is arranged on the side portion of the suction body, the guide bearing pedestal is arranged on the upper portion of the center of the suction body and connected with an impeller shaft through a guide bearing, and more than two eddy guiding blades are arranged on the periphery of the guide bearing pedestal. An opening hole is formed in the lower end of the guide bearing pedestal, the positioning column is arranged at the lower end of the suction body, and the upper end of the positioning column is fixedly arranged in the opening hole of the lower end of the guide bearing pedestal. According to the vertical pump eddy guiding suction device, a plurality of parts are integrated into a whole, guiding of flow is promoted, energy losses due to eddies are avoided, and meanwhile vibration and abrasion are reduced and stability of running is improved. The vertical pump eddy guiding suction device can completely replace an inflow water guide cone or an inflow runner, so that civil engineering and equipment installation are simpler, an engineering cycle is shortened, and engineering cost is reduced.
Description
technical field [0001] The invention relates to a vertical pump, more specifically, to a vertical pump guide vortex suction device. Background technique [0002] In small and medium-sized vertical pumps, at the inlet of the vertical pump, an inlet water guide cone or an inlet flow channel is usually used to guide the water flow. However, both the water inlet guide cone and the water inlet flow channel have the disadvantages of complex structure, difficulties in civil engineering and equipment installation, long engineering period, and high engineering cost. Contents of the invention [0003] In view of the above-mentioned shortcomings in the prior art, the object of the present invention is to provide a vertical pump guide vortex suction device with multiple functions, simple and convenient installation, and low cost. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] The guide vortex suction device of the verti...
