Miniature flood drainage pump station with vortex elimination and vibration reduction structure
According to the micro flood drainage pump station with the vortex elimination and vibration reduction structure, a water inlet pipe is of a double-water-inlet-pipe structure and comprises a main flow channel pipeline and an auxiliary flow channel pipeline, the inner diameter of the main flow channel pipeline is D1, and the inner diameters of the auxiliary flow channel pipelines are D2 and D1gt; d2; the main runner pipeline and the auxiliary runner pipeline form an inlet flow guide circular truncated cone structure at the joint of the bottom ends, the inlet flow guide circular truncated cone structure comprises a main runner side circular truncated cone cambered surface and an auxiliary runner side circular truncated cone cambered surface, the contour line of the main runner side circular truncated cone cambered surface is an arc, the arc radius of the main runner side circular truncated cone cambered surface is a main runner flow guide radius R1, and the contour line of the auxiliary runner side circular truncated cone cambered surface is an arc; the arc radius is the flow guide radius R2 of the auxiliary flow channel, wherein R1lt; r2; and a main runner flow guide structure at the front end and a main runner vortex elimination structure at the rear end are arranged in the main runner pipeline. As the structure of the pump station is improved, the flow characteristic is improved, the flow guide efficiency is improved, vibration and noise are reduced, and vortex is reduced and further eliminated.
