Description

Technical Field

[0001] The utility model belongs to the technical field of aviation engines, and in particular relates to a drainage and accumulated water recovery device for an exhaust water spray section of a combustion tester. Background Art

[0002] The combustion tester is an indispensable and important equipment for the development of aircraft engines. A large amount of high-temperature combustion gas (up to 2200k) is generated during the combustion chamber test. In order to meet the development of the combustion chamber of the new generation of engines, modern combustion tests are developing in the direction of wide working conditions, which leads to overheating damage to exhaust valves, pipelines and other equipment. Therefore, in order to protect exhaust valves, pipelines and other equipment from overheating damage, the exhaust water spray section of the combustion tester was developed. The exhaust water spray section cools down the high-temperature combustion gas by spraying water through the nozzle. However, the water droplets sprayed by the nozzle cannot be completely evaporated, which will cause a large amount of water to accumulate in the water spray section pipe. If the accumulated water cannot be removed in time, it will cause rust in the pipe for a long time, and the accumulated water in the pipe is not recycled, resulting in a certain waste of resources.

[0011] Furthermore, the inner diameter of the water pumping pipe is 10-20 mm.

[0012] The beneficial effect of adopting the above further technical solution is that the pumping pipe with an inner diameter of 10-20 mm can not only ensure the pumping efficiency of the drainage mechanism, but also reduce the space of the pumping pipe in the exhaust spray section.

[0027] like Figure 1 As shown, the water pumping pipe 21 is connected to the drain outlet 13, and a water pumping port 24 is arranged at one end thereof.
