An energy-saving cooling device

Abstract

The invention discloses an energy-saving cooling device, which comprises an oil inlet ring chamber and an oil outlet ring chamber arranged at both ends of a bearing bush. The inner diameter of the oil outlet ring chamber is larger than the inner diameter of the oil inlet ring chamber. The oil inlet seal plate and the oil outlet seal plate matched with the oil outlet ring chamber; the oil inlet seal plate is provided with an oil inlet pipe, and the oil outlet seal plate is provided with an oil outlet pipe connected with the oil inlet pipe; the functional area and the transduction area are separated by the seal plate, A cooling chamber is arranged at the end of the sealing plate close to the energy conversion area, and a heat exchange tube is arranged in the cooling chamber, and the two ends of the heat exchange pipe are connected with the oil inlet pipe and the oil outlet pipe respectively. This scheme can form a pressure difference when the main shaft rotates through the difference in diameter between the inlet and outlet oil ring chambers, so as to achieve the purpose of automatic oil inlet. The oil inlet operation can be automatically realized when the main shaft rotates without an oil pump, which reduces energy consumption. At the same time, there is no need to manually open the operation.

Description

Technical field [0001] The present invention pertains to hydroelectric turbine auxiliary means, in particular, is a kind of energy-saving type cooling device. Background technique [0002] Tubular turbine is mainly applied to the head 1 ~ 25m, it is a special type low head high flow hydropower. Because of its flow in the runner substantially move axially, not turning, and thus the water capacity of the hydraulic unit efficiency can be improved. Especially suitable for tidal power plant, its bi-generation, two-way and two-way draining water pumping and other functions it is suitable for low head hydro resources utilization. Due to the current high-head hydropower resources development and exhausted, exploitable hydropower resources are mostly low-head, tubular turbine for low head, high efficiency and low investment, rapid development in recent years, but power is also growing. [0003] A shaft extending tubular turbine guide bearing mounted in the turbine inlet passage closed in ...

AI Technical Summary

Problems solved by technology

Most of the existing cooling systems require a high-power oil pump to inject cooling oil into the connection between the bearing bush and the main shaft. At the same time, cooling equipment is also required to cool the heated oil for circulation. The long-term opening of multiple electrical components will cause Greatly increase the energy consumption of cooling, not easy to use
