Definitions

  • the tank 9 is configured as a double structure tank having an inner tank and an outer tank.
  • a vacuum layer for vacuum insulation is formed between the inner tank and the outer tank.
  • the configuration of the tank 9 is not limited to this example.
  • the tank 9 may have a vacuum insulation layer filled with powdered insulation such as perlite, which is a granular insulation.
  • the tank 9 may be a single-hull tank 9 covered with an insulating material.
  • the heat insulating material in this case may be composed of, for example, a plurality of vacuum insulation panels or a plurality of foam panels.
  • the evacuation device 1 can be provided with various valves and pressure measuring devices as necessary.
  • a second on-off valve 59 is provided in the middle of the evacuation pipe 15
  • a compound gauge 61 is provided on the ejector 17 side of the second on-off valve 59 .
  • the evacuation device 1 can be installed in a dangerous place regardless of whether the evacuation device 1 is installed in a timely manner or permanently installed as described above.
  • the term "dangerous place” as used herein refers to a place where flammable or explosive substances are present and there is a risk of leakage, etc., and therefore explosion-proof performance and the types of equipment that can be installed are regulated by various standards.
  • the vacuum pumping device 1 according to the present embodiment can be installed, for example, in a type 2 hazardous area around the tank 9 (FIG. 2).
