複雑になり、保守性も悪くなる。 The conventional mechanical seal cooling device is "Mechanical Seal" E, Meyer, Kagaku Shinbunsha 1971.
As described in December 10, 2016, pages 198-199, the shaft sealing chamber and sealing liquid tank are connected with two pipes, and the sealing liquid is naturally circulated only by the thermosiphon effect. . However, it is difficult to sufficiently cool the sealing liquid in the shaft sealing chamber only by the thermosiphon effect, and the mechanical seal portion may not be sufficiently cooled. In this case, a method is adopted in which a seal liquid circulation pump is installed in the piping to forcefully circulate the seal liquid and cool the mechanical seal, but using a pump complicates the structure and makes maintainability worse. .

The sealing liquid 7 in the shaft sealing chamber 1 is guided into the shaft sealing chamber 1 through the shaft sealing piping 4, and the sealing liquid 7 in the shaft sealing chamber 1 is cooled by natural circulation. The sealing liquid in the sealing liquid tank 2 is cooled effectively by the cooling coil 5 via the cooling coil 6 .

ことができる。 As described above, the present invention is a cooling device for a mechanical seal that naturally circulates sealing liquid using a thermosiphon effect, in which a heat pipe is provided penetrating the shaft sealing piping that connects the shaft sealing chamber and the sealing liquid tank. This allows the sealing liquid in the shaft sealing chamber to be cooled more effectively.
It is possible to obtain a mechanical seal cooling device that does not require a pump or the like, has a simple structure, is inexpensive, and has good maintainability.
