torque-converter fluid

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。

Speed fluid drive top-head , large-torque, easily directional drilling.

动力头转速为无线调速,扭矩大,造斜 、 变向方便.

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

The fluid cavity should be smooth, continuous, and symmetrical to minimize fluid torque.

为了减省液体力矩,液体腔应该是光滑的, 连续的和对称的.

Theoretical analysis, onboard test and bench test show that this phenomenon is determined by natural blast torque after throw-out of marine fluid coupling as well as damping torque of shafting.

理论分析、码头试验及台架试验表明，该现象是由液力偶合器固有的脱排鼓风转矩与轴系阻尼转矩大小决定的。
