Lubricating-oil mist discharging device for oil groove of sliding bearing of generator set

Abstract

The invention discloses a lubricating-oil mist discharging device for an oil groove of a sliding bearing of a generator set. The lubricating-oil mist discharging device comprises an oil groove cover, wherein an air inlet and an air exhaust port are formed in the oil groove cover; an air filter is arranged on the air inlet, and outside air is filtered by the air filter and then enters the oil groove; the air exhaust port is provided with a splash-proof oil retaining cover which is provided with an oil-mist discharging device; the splash-proof oil retaining cover is provided with an enveloping part which is arranged in the circumferential direction; the outer edge of the top part of the enveloping part is provided with a first connecting part; a bottom plate is arranged at the bottom part of the enveloping part; the enveloping part is internally provided with a labyrinth passage; and a labyrinth-passage inlet as an air inlet of the splash-proof oil retaining cover is arranged at the side wall of the enveloping part, and a labyrinth-passage outlet as an air exhaust port of the splash-proof oil retaining cover is arranged at the top part of the enveloping part. The lubricating-oil mist discharging device disclosed by the invention has the advantages that the purpose of purifying oil mist can be achieved, the oil mist discharging device also can be protected, and a first groove plate and a second groove plate are mutually embedded to play a role of accelerating the backflow of reflux and liquefied lubricating oil into the oil groove.

Description

technical field [0001] The invention relates to a lubricating oil oil mist discharge device used for a sliding bearing oil tank of a generator set. [0002] Background technique [0003] Due to the fast stirring speed of lubricating oil in the oil tank, high-speed generator sets are prone to oil splashing and oil mist, which not only pollutes the environment but also may cause insulation accidents. [0004] Hydrogenerator bearings generally use self-lubricating sliding bearings, and the bearing pads are infiltrated in lubricating oil. When the unit is running, on the one hand, the lubricating oil stirs and collides in the oil tank, producing a large number of air bubbles, which burst to form oil mist; For generators, the generation of oil mist is inevitable, and with the increase of the unit speed, the oil is splashed everywhere, and the severity of oil mist increases. [0005] In order to solve the problem of oil mist in hydroelectric generating units, methods such as ex...
