And the same size compared to other types, this type of bearingfriction small, high-limit speed.
与尺寸相同的其它类型比较,此类轴承摩擦系数小,极限转速高。

This turning force in a butterfly valve is determined by three factors. (1) friction of the disc to seat for sealing (2) Bearingfriction (3) Dynamic torque.
The model of system loss model caused by wind resistance and bearingfriction is established based on the regression analysis of flywheel's free brake curve.
