Description

Technical Field

[0001] The utility model relates to the field of hydroelectric mechanical equipment, in particular to a disc-type oil cooling device for a water turbine. Background Art

[0002] The water wheel of the water turbine is installed on the frame through the bearing, and the connection with the frame is equipped with a sealing device. The lubricating oil for the bearing is generally stored directly in the rotating box. As the water wheel rotates for a long time, the oil temperature rises, expands, and overflows, causing the bearings and bushings to lock. Therefore, new lubricating oil needs to be continuously injected to ensure the normal operation of the equipment. However, continuously injecting new lubricating oil is troublesome, difficult to inject in an appropriate amount and accurately, and wastes lubricating oil, resulting in low work efficiency. The existing water turbine lubricating oil cooling method generally uses the residual wind of the cooling engine to cool the lubricating oil. This cooling method is difficult to achieve a good cooling effect. The poor cooling effect of the lubricating oil often causes the engine temperature to rise and the output power to decrease. In severe cases, it will cause engine failures such as pull-up and cylinder sticking, thereby affecting the normal use of the engine.

[0003] For this purpose, we propose a disc-type oil cooling device for a water turbine. Utility Model Content

[0022] Embodiment: A disc-type oil cooling device for a water turbine, such as Figure 1-Figure 3 As shown, it includes an installation body 1, the inner cavity of the installation body 1 is fixedly installed with a spiral oil pipe 3, the two ends of the spiral oil pipe 3 are respectively connected with an oil inlet pipe 301 and an oil outlet pipe 302, the oil inlet pipe 301 and the oil outlet pipe 302 are respectively located on both sides of the installation body 1, the top of the installation body 1 is connected with a water inlet pipe 101, and external cooling water can enter the interior of the installation body 1 through the water inlet pipe 101, and one side of the bottom of the installation body 1 is connected with a water outlet pipe 102, and a water storage tank 2 is fixedly connected to the front side wall of the installation body 1, and a first water pump 202 is installed on one side of the water storage tank 2, and the water inlet end of the first water pump 202 is connected to the inner cavity of the water storage tank 2. The water outlet end is fixedly connected with a circulation pipe 201, which passes through the inner cavity of the installation body 1 and is wound and connected to the side wall of the spiral oil pipe 3. A plurality of first heat exchangers 203 are installed at the other end of the circulation pipe 201 and are connected with the wall of the water tank 2 close to the oil inlet pipe 301. A second water pump 206 is installed at the center of the bottom of the installation body 1. The water inlet end of the second water pump 206 is connected to the bottom of the water tank 2. The water outlet end of the second water pump 206 is connected with a connecting pipe 204. The connecting pipe 204 is an L-shaped structure as a whole.

[0023] The working principle of this utility model:

[0024] During use, the user connects the water inlet pipe 101 to the external cold water tank, the cooling water enters the installation body 1 through the water inlet pipe 101, and the lubricating oil enters the spiral oil pipe 3 through the oil inlet pipe 301. When the cooling water enters the inner cavity of the installation body 1 through the water inlet pipe 101, the lubricating oil in the inner cavity of the spiral oil pipe 3 can be initially dissipated. The water in the inner cavity of the installation body 1 passes through the second water pump 206 and re-exchanges heat with multiple second heat exchangers 205 so that the temperature of the cooling water is reduced again and then returns to the inner cavity of the water storage tank 2. By starting the first water pump 202, the re-cooled cooling water is circled by the circulation pipe 201 for one circle, and then the heat absorbed on the wall of the spiral oil pipe 3 is lowered again by the multiple first heat exchangers 203. Since the circulation pipe 201 is wrapped around the side wall of the spiral oil pipe 3, the lubricating oil in the inner cavity of the spiral oil pipe 3 can be dissipated for a second time.
