Method for rectification of bottoms of Archimedean screw grid bars of integrated pump station
The invention relates to a water conservancy project facility, in particular to a method for rectification of the bottoms of Archimedean screw grid bars of an integrated pump station, and belongs to the technical field of water conservancy projects and municipal engineering. The method is characterized in that a pump cylinder is formed by an upper cylinder body and a cylinder bottom, the cylinder bottom is a curved surface cylinder bottom and formed by a spherical-crown-shaped curved surface and an annular curved surface, and the slope becomes smaller gradually; the upper edge of the annular curved surface is tangent to the cylinder body, and the lower edge of the annular curved surface is tangent to the edge of the spherical-crown-shaped curved surface; an Archimedean screw grid formed by the anticlockwise Archimedean screw grid bars is arranged in the bottom of the curved surface cylinder; a pulverizing screen is arranged in a water inlet, and impurities in water flow which flows in from a water inlet are smashed through the pulverizing screen and then enter the pump cylinder. According to the method for rectification of the bottoms of the Archimedean screw grid bars of the integrated pump station, the structure is reasonable and simple, production and manufacturing are easy, and the method is advanced and scientific.
