Abstract
The utility model discloses an ultra-low ratio rotating speed runner for a mixed-flow turbine of a cooling tower. The ultra-low ratio rotating speed runner comprises a crown at the center side, a lower ring arranged at the periphery of the crown, and a guide vane connected to the crown and arranged at the inner circle of the lower ring. The ultra-low ratio rotating speed runner is simple in structure, and is connected to an output shaft of the water turbine, so that the situation that output shaft of the runner can be directly connected with a cooling tower fan is ensured, and components such as a speed reducer and the like are concealed. The output shaft of the runner is directly connected with a wind impeller of the fan, so that the operating reliability of the cooling tower is increased; the operation expense is reduced, and the service life of the cooling tower is prolonged.
Description
Technical field
The utility model relates to the cooling tower field, specifically a kind of cooling tower Francis turbine ultra-low specific speed runner.
Background technique
Water kinetic energy recovery cooling tower comprises tower body, is arranged at water turbine and fan blade in the tower body, traditional water kinetic energy recovery cooling tower is higher with its output shaft rotating speed of water turbine, the rotating speed of blower fan of cooling tower is lower, so must increase by a cover retarder at outgoing position, reduce output speed, but owing to having increased retarder, cause output resistance to become large, and rate of fault raise.
The model utility content
The technical problems to be solved in the utility model provides a kind of cooling tower Francis turbine ultra-low specific speed runner, and the output shaft of runner can directly be connected with blower fan of cooling tower, and is simple in structure, long service life.
The technical solution of the utility model is:
Cooling tower Francis turbine ultra-low specific speed runner comprises being arranged at the crown of central side the lower ring of crown periphery and being connected in the stator of labeling and being positioned at lower ring inner ring.
The utility model is simple in structure, be connected on the output shaft of water turbine, the output shaft that guarantees runner can directly be connected with blower fan of cooling tower, the parts such as retarder have been cancelled, by the fan blade of the direct connecting fan of runner output shaft, the working life that has increased the operational reliability of cooling tower and reduced operation expense, improved cooling tower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, cooling tower Francis turbine ultra-low specific speed runner comprises the crown 1 of central side, is arranged at the lower ring 2 of crown 1 periphery and is connected on the crown 1 and is positioned at the stator 3 of lower ring 2 inner rings.
