Nowadays, the application of liquid nitrogen has become more and more extensive, the need for liquid nitrogen industry is also more and more. However, liquid nitrogen can not be preserved in a conventional environment and needs to be stored and transported in a container of traits, which is a liquid nitrogen tank.
  Aviation liquid nitrogen tank as a storage of liquid nitrogen and other special low-temperature liquid settings, the daily inspection and maintenance is very important, or easily produce a variety of problems and failures. So, when we use and save the cryogenic liquid tank, what should be done to check the daily maintenance work?
  1, valves, piping is leaked, whether the shell frost, sweating.
  2, all valves are in the normal state of opening and closing.
  3, low-temperature liquid storage tank instrument (level gauge, pressure gauge) work is normal, DCS display parameters and the scene is consistent with a table.
  4, the tank pressure is normal, when the pressure close to or equal to the maximum pressure, the need to open the vent valve pressure relief.
  5, the liquid filling rate is more than 95%.
  6, cryogenic liquid storage tank for the atmospheric pressure powder insulation tank, sealing gas is normal. (50mmH2O) 7, liquid oxygen storage tank is strictly prohibited near the placement of flammable, explosive materials and all debris.
