Embodiment 1

[0030] refer to figure 1 , a water turbine outlet base structure, including a base body 1 arranged at the bottom of the water turbine, the base body 1 is an axisymmetric structure, and a water guide member 2 is arranged on the symmetrical center of the base body 1 to guide the direction of water flow and prevent water flow from hitting. By arranging the water guiding member 2, the vibration generated by the impact of the turbulent flow on the water turbine caused by the turbulent flow when the water turbine is discharged is reduced, and the efficiency of the water turbine is improved.

[0031] refer to figure 2 The base body 1 includes a bottom plate 11 arranged at the bottom of the base body 1, a water outlet pipe 12 arranged on the bottom plate 11 with the center of the bottom plate 11 as a symmetrical center, a cylinder 14 arranged above the water outlet pipe 12, and a cylinder 14 arranged at the top of the cylinder 14. flange13.

[0032] Preferably, at least two water o...

Abstract

The invention discloses a water turbine water outlet base structure. The structure comprises a base body arranged at the bottom end of a water turbine, the base body is of an axisymmetric structure, awater guide component is arranged on the symmetric center of the base body and used for guiding the water flow direction, so that the water flow is prevented from being impacted. According to the structure, the problems that turbulent flow occurs when the water out of an existing water turbine passes the water outlet base, and the turbulent flow impacts the water turbine so as to generate vibration and then influence the efficiency of the water turbine can be avoided.

Description

technical field [0001] The invention relates to the field of water turbines, in particular to a water outlet base structure of a water turbine. Background technique [0002] With the rapid development of China's industry, the cooling tower ushers in a good development prospect. Driven by demand, cooling tower manufacturers have stepped up scientific research efforts and continued product innovation, which has well met market demand. Refrigeration equipment is an ideal water-saving equipment for modern industrial and mining enterprises such as chemical industry, electric power, metallurgy, prevention and papermaking, and various civil projects to realize equipment cooling or circulating water cooling in air-conditioning refrigeration. It is mainly used in air-conditioning cooling systems, refrigeration series, injection molding, tanning, foaming, power generation, steam turbines, industrial water cooling and other fields. [0003] Existing hydraulic turbines, such as the co...
