为探讨偏心柱塞的液体漏耗及受力特点 ,对准二维Reynolds方程进行数值求解 ,获得柱塞受力分布的三维曲面及漏耗特征曲线 ,分析了偏心率对柱塞自扶正能力的影响 ,讨论了极限偏心位置对密封性能及设备磨损的影响 ,结果表明 :柱塞偏心位置是造成内漏耗不可忽视的因素 ;在适当的偏心率下 ,柱塞保持一定的自扶正能力 ;处于极限偏心位置的柱塞会丧失自扶正能力 ,这是高压轴密封极为危险的位置 ,是制约更高压力生成的重要因素 In order to investigate the liquid leakage and stress characteristics of eccentric plunger, the two-dimensional Reynolds equation is numerically solved to obtain the three-dimensional curved surface and the leakage characteristic curve of the plunger force distribution. The influence of eccentricity on self- The results show that the eccentric position of the plunger is the factor that can cause the internal leakage to be neglected. Under proper eccentricity, the plunger maintains a certain self-righting ability, Extremely eccentric position of the plunger will lose self-righteousness, which is a very dangerous high-pressure shaft seal position is an important factor restricting the generation of higher pressure
