breakaway torque

A key factor restricting the application of magnetic fluid rotation sealing at low temperature and large diameter is the high breakaway torque.

制约低温大直径磁性液体密封在实际应用中的关键因素之一是起动扭矩过大。

Study on the breakaway torque of magnetic fluid sealing at low temperature and large diameter

低温大直径磁性液体密封起动扭矩的研究

At low room temperature we studied such influencing factors on the breakaway torque as injection quantity of magnetic fluid, number of sealing stages, and the standing time at normal temperature.

以-40℃，直径为140mm的磁性液体密封为例，在低温室内研究了影响磁性液体密封起动扭矩大小的因素，如磁性液体注入量，密封的级数、常温（15℃）下放置的时间等。

Breakaway Torque is the total of the three factors listed above.

最小开机扭矩是上述三项因素的总和。
