Abstract

The invention belongs to the field of water conservancy projects, and particularly relates to a water turbine cooling device. The water turbine cooling device comprises a fixing disc, a water conveying device is fixedly connected to the middle of an inner cavity of the fixing disc, adjusting water spraying pipes are fixedly connected to an inner cavity of the water conveying device, the right ends of the adjusting water spraying pipes extend out of the water conveying device, a supporting disc is fixedly connected to the outer surface of the adjusting water spraying pipes, a water turbine is rotationally connected to the top end of the water conveying device, and the upper surface of the supporting disc is movably connected with the lower surface of the water turbine. Different from common large-area cooling, the device applies main power to pressurization of cooling liquid, so that the flow of the cooling liquid of the device is faster, a stronger cooling effect is obtained, energy waste is reduced, the spraying direction of the cooling liquid is adjusted by the adjusting water spraying pipes, a heat source can be accurately cooled, the situation that a water turbine device is corroded due to long soaking time caused by large-range cooling is avoided, and the fault rate of the water turbine is reduced.

Description

technical field [0001] The invention belongs to the field of hydraulic engineering, in particular to a water turbine cooling device. Background technique [0002] Due to the influence of the environment, working conditions and water flow during the operation of the turbine, the temperature of the bearing bush will inevitably rise due to friction. Generally speaking, the temperature rise of the bearing bush within the normal threshold will not affect the working efficiency and safety of the Francis turbine. However, once the temperature of the bearing bush rises too high, it will not only bury hidden dangers in production safety, but also shorten the service life of the turbine and bring unnecessary economic losses to the enterprise. [0003] Most of the existing water turbine cooling devices are used to cool the whole water turbine, but this cooling method is too simple to effectively cool the heat source, which leads to the cooling device using a lot of energy, and the cool...
