Definitions

  • this liquid leak detection unit it is possible to more accurately grasp the maintenance time of the sealing material and to provide the liquid leak detection unit for preventing the occurrence of the liquid leak.
  • the liquid leak detection unit 100 in the present embodiment has a first rod seal 23A as a primary seal, a second rod seal 23B as a secondary seal, and a modified dust seal 26 as a tertiary seal.
  • the basic configuration of the liquid leak detection unit 100B in the present embodiment is the same as the liquid leak detection unit 100 shown in the above-described first embodiment, and the difference is that the liquid information of the liquid located in the inter-seal space 65 While the first pressure sensor 110 is used in the first embodiment as the first liquid information acquisition device for obtaining the second liquid pressure information, the pressure switch 110B is used in the present embodiment.
  • the liquid information acquisition device is not provided on the application port 170P side.
