Description

Bearing oil basin respirator for preventing oil mist leakage and lubricating oil from being damped

Technical Field

The utility model relates to a bearing oil pan respirator, especially a prevent that oil mist from revealing and bearing oil pan respirator that lubricating oil wet.

Background

The unit of the pumping power station has high operation speed, and when the unit reaches the rated speed, the centrifugal force makes the lubricating oil rotate at high speed all the time, so that the liquid splashes, atomizes and collides to form oil mist. The existence of oil mist causes the inside of the oil basin to form positive pressure, so a respirator is arranged to balance the internal pressure. The technical measures generally adopted at present are as follows: the oil basin is provided with a hole, the lower part of the oil basin is provided with a porous metal steel cylinder, and the upper part of the oil basin is provided with a porous hollow cap which has the function of balancing the internal pressure. The analysis of the running conditions of a plurality of power stations shows that lubricating oil overflows frequently around the respirator, the site safety and civilized production is seriously influenced, and the ecological environment of the power station basin is polluted. In addition, the pump storage unit is mostly underground factory building, and factory building humidity is great, and inside open space steam got into the oil pan easily, caused lubricating oil moisture to exceed standard, and then threatened bearing equipment safe operation. From the comprehensive field treatment situation of the actual plant operation, the spilled lubricating oil comes from: (1) In the high-speed rotating unit, lubricating oil in an oil basin forms a parabola under the action of centrifugal force to form increased oil pressure, and the oil is sprayed out from the lower part to the upper part of a tile at a high speed. The upper part of the tile is provided with a circle of oil baffle plate to improve the oil lubrication effect. The oil sprayed at high speed impacts the oil baffle plate, so that more disordered and splashed oil exists on the upper part of the oil basin and is easy to overflow from the respirator with the opening; (2) The inside hot oil mist of oil pan gathers because chimney effect, and oil mist also spills over from this opening, so there is the oil mist to reveal and the problem that lubricating oil wet in the in-process of present pumping power station unit operation, not only can the polluted environment, still can cause the damage to the unit.
