てなることを特徴とする軸封装置。 In a shaft sealing device that seals a high-pressure space, there is a mechanical seal that is airtightly interposed between the housing and the rotating shaft, and a collar that is pressed in the axial direction by a spring and whose end face facing the mechanical seal is fixed to the inner circumference of the housing. A non-rotating floating ring that is in close contact with the end wall of the housing, but floats in the radial direction without contacting the outer periphery of the rotating shaft, and partitions the high pressure space and the shaft seal space around the mechanical seal. 1. A shaft sealing device comprising a guide hole through which a flushing liquid that maintains a lower pressure in a sag shaft sealing space than a high pressure space flows.
