摘要
鉴于传统密封在化工机械使用中的泄露问题,公司提出采用磁流体密封,为了在磁流体密封结构的密封间隙内获得最大的磁能积以及提高密封的耐压能力.避免因压力和温度过高而导致密封的失效,对磁流体的密封结构进行了优化设计,通过有限元方法计算了迷宫密封的压力分布、转轴温度变化和磁流体的耐压能力。结果表明:优化后的磁流体密封结构满足耐压和温度的要求。
In view of the traditional seal leaks in chemical machinery, the company proposed to use the ferrofluid seal for getting the maximum magnetic energy product and improving the seal pressure, resistance in the gap of the seal structure, and avoiding the high pressure and temperature which lead to failure of the seal. The ferrofluid seal structure design was optimized by using the finite element method to calculate the labyrinth seal pressure, the temperature of the shaft and the resistant to the pressure of the ferrofluid seal. The results show that: the optimized ferrofluid seal structure meet the requirements of the pressure and temperature.
