Abstract According to the trouble of lube leakage of the turbine principal axis, this paper conduct an investigation in the cause of the trouble. The theory analysis indicates the form of the disk friction pump when the open hull is replaced by closed hull. In a broad sense it realizes the change from pour to ejection, and the gap flow near pump hull change from leakage flow to suction flow. Practice indicates that measures, which is took here, is practical, and the trouble of lube leakage of the turbine principal axis is well resolved.
