Study on Lubrication Performance of Water-lubricated Thrust Bearing in Submersible Pump
Based on computational fluid dynamics,different water-lubricated bearing models were established,and thrust tiles were simulated under different dimensions,aspect ratio,speed,load and materials.The geometric parameters were optimized by comparing the results of pressure distribution,film thickness and load bearing capaci-ty.The results show that the sector tile has a higher area utilization rate and can provide a higher load bearing ca-pacity.The thickness of water film decreases with the increase of bearing capacity.When the bearing speed and tile Angle are constant and the tile aspect ratio is 1.2,the bearing bearing capacity is the highest.The hardness of the material is positively correlated with the bearing capacity.
