Direct-connection low-speed small mixed-flow hydroturbine for hydrodynamic energy-saving cooling tower

摘要

A direct-connection low-speed small mixed-flow hydroturbine for a hydrodynamic energy-saving cooling tower has a spiral casing (1), a seat ring (2) circumferentially provided with a single row of guide vanes, a runner, a right-conical water outlet tube (9) and a side water outlet tank (10). The seat ring (2) is installed inside the spiral casing (1), and the water outlets between the guide vanes in the seat ring (2) are communicated with the water inlets formed between the curved surface blades (4). The water outlets formed between the curved surface blades (4) are communicated with the water inlet of the right-conical water outlet tube (9). The water outlet of the right-conical water outlet tube (9) is communicated with the water inlet of the side outlet water tank (10). A bearing seat (6) is installed on the runner. A shaft (7) is installed in the bearing seat (6), said shaft (7) being directly fitted with cooling fan blades. The hydroturbine is small in size with high efficiency and low noise.
