Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to an oil drainage device for a sealed oil tank that is convenient for measurement. Background Art

[0002] The hydrogen-side oil drainage of the single-flow ring sealing tile of the generator passes through the float oil tank and the circulating sealing oil tank (air extraction tank), and then returns to the main oil tank through the lubricating oil return pipeline. A mechanical float ball valve for automatically controlling the oil level is installed inside the float oil tank. The float ball valve uses the principle of the float lever to control the opening and closing of the valve, thereby controlling the oil level within a certain range, ensuring that the oil seals the hydrogen to prevent leakage, and also ensuring normal oil drainage on the hydrogen side. At the same time, an oil drainage bypass and an observation window are set for manual operation to control the oil level in case of a float oil tank failure.

[0003] During the use process, it is found that the float ball valve will get stuck. When the float ball valve gets stuck in the open position and the handling is not timely, the oil seal of the float oil tank will be damaged, and a large amount of hydrogen in the generator will leak. When the float ball valve gets stuck in the closed position and the handling is not timely, the hydrogen-side oil drainage will be blocked, resulting in oil ingress into the generator, both of which seriously affect the safe operation of the equipment unit.
