Guide bearing clearance is too small, the vibration of the rotating shaft will be transferred to the bearing and foundation, the bearing clearance is too large, the rotating shaft vibration.
导轴承空隙过小，会把转动轴的振动传给支座和基础，导轴承空隙过大，转动轴振动大。

In the last treatment, it was discovered that the problem was caused by loose rotor pole that led to augmented shaft swing and bigger clearance of lower guide bearing.
It is highly important to the efficiency guide line of the whole hydraulic equipment unit and to the unit runs safety and steadily that the wicket gate end clearance of the hydraulic turbine.
