Rotating anode X-Ray tube and X-Ray generator

摘要

A coolant passage (44) is formed inside the rotary shaft (24) while an air passage (60) is formed inside the casing (20). A mechanical seal (32) is arranged between the coolant passage (44) and the air passage (60). Leakage cooling water, which has leaked in the form of vapor from the mechanical seal (32), is relegated radially outwardly along with air by the action of a rotary vane (66), which is disposed in the air passage (60), and finally flows out of an air outlet (64). A coolant sensor (102) may be provided to early detect the leakage water.
