利用FLUENT软件对浮动环密封进行模拟分析的结果表明,由于楔形效应,浮动环所受液体作用力不均匀且不对称,断面最大压力不在最小间隙处,而在液体流向最小间隙处的楔形区域。压力大的地方阻漏效果好,压力小的地方阻漏效果差;随着转速增加泄漏量减小,间隙内液体阻力增加;随密封环两侧压差增加,泄漏量增大;随偏心距增大,泄漏量增大,密封间隙内压力分布越不均匀。 The simulation results of the floating ring seal by FLUENT software show that due to the wedge effect, the force acting on the floating ring is uneven and asymmetrical, and the maximum pressure in the section is not at the minimum clearance, but at the wedge-shaped area where the liquid flows to the minimum clearance. Strong pressure blockade effect is good, the place where the pressure is small, the obstruction effect is poor; as the rotational speed increases, the leakage reduces, the liquid resistance in the gap increases; with the differential pressure on both sides of the seal ring increases, the leakage increases; Increase, the amount of leakage increases, the more uneven distribution of pressure within the seal gap.
