Claims

[Scope of utility model registration request]

The periphery of the rotating shaft protruding from the outside of the machine is sealed by a mechanical seal mechanism built into the inner diameter part of the seal cover, and flushing water is supplied from the flushing hole provided in the seal cover to the shaft sealing part of the mechanical seal mechanism. In the shaft sealing device that performs cooling by supplying water, a case is disassembled and provided on the inner diameter part of the seal cover so as to cover the outer periphery of the shaft sealing part of the mechanical seal mechanism, and the shaft sealing part of the mechanical sealing mechanism of the case is disassembled. A shaft sealing device characterized in that a plurality of ejection holes are provided in a circumferential direction at positions close to and corresponding to a sliding surface of the shaft sealing device.
