Abstract

The invention discloses a closed circulation system for sealing and collecting oil fog of a generator. The closed circulation system comprises a rotatable part of a generator thrust bearing or a guide bearing and an oil groove for surrounding the rotatable part, wherein the upper part of the oil groove is provided with a sealing cover, and a sealing structure arranged between the sealing cover and the rotatable part is used for isolating the oil groove and the outside; the sealing cover is respectively provided with an air inlet, an exhaust hole and an oil return hole communicated with the oil groove, the rotatable part of the generator is provided with a fan, and the sealing cover or an oil groove cover is provided with an oil fog collector; the oil fog collector is communicated with the exhaust hole through an oil-taking fog pipe, the outlet of the oil fog collector is communicated with the air inlet, and an oil liquid agglutinated by the oil fog collector is inputted into the oil return hole through an oil return pipe. The closed circulation system provided by the invention has the advantages that the oil fog is limited in a space formed by the oil groove, the oil fog collector and the oil-taking fog pipe, the oil fog is agglutinated by the oil fog collector into a liquid state to reflow in the oil groove, so that the sealing and collection of the oil fog are realized, and an overflowing problem of the oil fog is solved.

Description

[0001] technical field [0002] The invention relates to the technical field of oil mist sealing and collecting systems for generators. Background technique [0003] Generator bearings generally adopt sliding bearings, and the bearing pads are soaked in lubricating oil. When the unit rotates, on the one hand, the lubricating oil stirs and collides in the oil tank, generating a large number of bubbles, which burst to form oil mist; Therefore, the generation of oil mist is inevitable, and with the increase of the speed of the unit, or the increase of the line speed of the rotating parts at the tile surface of the unit, the severity of the oil mist will increase. During the operation of the unit, the oil mist accumulates continuously, the oil mist concentration and gas pressure in the oil tank increase, and the oil mist will overflow from the sealing structure. The overflowing oil mist will pollute the generator and the environment. In very serious cases, it may cause a s...
