Through the annular pipeline that the slope set up, the guide bearing oil after making the separation can flow back to in the oil pan. The construction is simpler, and the effect is more obvious.
Description
Technical Field
The utility model relates to a separation device, in particular to an oil-gas separation device for a guide bearing oil basin respirator, and belongs to the technical field of hydroelectric generation.
Background
The hydraulic generator is cooled by adopting a closed circulating air cooling mode, and the wind tunnel of the cooler is in a closed state. The guide bearing of the water turbine is cooled in a water cooling mode, and the temperature of lubricating oil in the guide bearing is lower than the ambient temperature in the wind tunnel during operation. In order to balance the positive pressure and the negative pressure in the oil basin of the guide bearing in the operation process, a respirator is usually arranged on the oil basin cover, and a large amount of oil mist is suspended above the oil surface in the oil basin due to the temperature difference between the inner side and the outer side of the oil basin, and the oil mist leaves the oil basin along with the respirator and is deposited at all corners in wind tunnels such as an air cooler, a stator and a rotor to cause oil pollution. Meanwhile, oil stains accumulated on the surfaces of the cooling copper pipes and the fins of the air cooler can reduce the heat exchange effect of the air cooler, and the safe and stable operation of the unit is seriously threatened. There is therefore a need for improvements in the art.
Disclosure of Invention
The utility model provides an oil-gas separation device for a guide bearing oil basin breather, which aims to solve the problems that a large amount of oil mist is carried out when the existing oil basin breather breathes and enters a hydraulic generator cooler, so that the cooler is polluted by oil stains and the heat exchange of the cooler is affected.
The utility model is completed by the following technical scheme: the utility model provides an oil-gas separation device for guide bearing oil basin respirator, including the epaxial guide bearing oil basin of hydraulic turbine pivot is located to the cover of locating the oil basin at guide bearing oil basin top, its characterized in that cover top of oil basin is equipped with annular duct, be equipped with a plurality of respirators on the annular duct, and annular duct bottom is linked together with guide bearing oil basin through many connecting pipes, and be equipped with radiating fin on annular duct, after introducing annular duct internal cooling through the respirator with the oil mist, accomplish the abundant separation of oil gas, the guide bearing oil of separation flows back to the oil basin along annular duct, connecting pipe, thereby avoid oil to get into the hydraulic turbine cooler along with the respirator and cause the pollution.
The annular pipeline is an inclined annular pipe with one high side and one low side, so that separated guide bearing oil can flow back into the guide bearing oil basin from high to low through the inclined annular pipeline.
The oil pan is characterized in that the plurality of connecting pipes are uniformly distributed between the annular pipeline and the guide bearing oil basin, the plurality of connecting pipes are arranged into vertical pipes with different heights, the upper end of each vertical pipe is communicated with the bottom of the annular pipeline, the lower end of each vertical pipe is communicated with a through hole in the oil basin cover, the guide bearing oil basin and the annular pipeline are communicated through the connecting pipes, oil mist in the guide bearing oil basin can enter the annular pipeline, and guide bearing oil separated by the breathing apparatus flows back into the guide bearing oil basin through the vertical pipeline.
The radiating fins are arranged as annular sheets and are arranged on the annular pipeline so as to improve the radiating effect of the annular pipeline.
The respirators are conventional products, are arranged in a plurality of ways and are uniformly distributed on the annular pipeline.
The utility model has the following advantages and effects: by adopting the scheme, the circulating path of oil mist can be increased through the annular pipeline, and the oil mist entering the annular pipeline can be cooled as soon as possible, so that oil and gas can be fully separated, and the oil is prevented from entering the water turbine cooler along with the respirator. Through the annular pipeline that the slope set up, the guide bearing oil after making the separation can flow back to in the oil pan. The construction is simpler, and the effect is more obvious. Is an ideal oil-gas separation device.
