Taking a roller bearing as an example: thin oil lubrication is not suitable for structural reasons. The oil consumption of the dry oil lubrication is 30 times of that of the oil gas lubrication, so that the pollution to the running environment and cooling water of the roller can be caused, and the lubrication is uneven due to different accepting points in the running process, so that the service life of the bearing is influenced. Although oil mist lubrication has good lubrication effect, low oil consumption and good heat dissipation effect, the oil mist lubrication must use a large-caliber pipeline, the transmission distance cannot exceed 80 meters at maximum, and the oil mist lubrication has a great influence on the viscosity change of oil, so that the oil temperature must be strictly controlled, and in addition, the oil mist contains tiny oil particles which are partially suspended and are harmful to human health, so that ventilation facilities must be additionally arranged, and the cost is increased.
The oil-gas lubrication is used as a novel gas-liquid two-phase fluid cooling lubrication technology, and has great superiority compared with the traditional single-phase fluid lubrication technology, but under the occasion that the lubrication point exceeds 200, the conventional pneumatic oil-gas lubrication system cannot meet the requirement, and the oil-gas flow transportation of a plurality of lubrication points must be realized through the expansion of a plurality of satellite stations. Moreover, when the distribution of the lubrication points is concentrated and the difference of the required lubrication oil amounts of the lubrication parts is increased, the lubrication oil is wasted, and the cost is increased.
