Description

technical field [0001] The invention relates to the technical field of airtight cabin testing, in particular to a pressure testing system and a testing method for an airtight cabin of a ship. Background technique [0002] When a surface ship passes through an epidemic-contaminated area, in order to protect the crew from the threat of the epidemic and ensure the normal completion of maritime tasks, the cabins in some areas on the ship are designed to be airtight, and the airtight cabins need to be pressure tested during the construction process. [0003] Existing pressure test methods, such as the Chinese invention patent application with the application publication number CN107966310A and the application publication date of 2018.04.27, disclose an automatic pressure maintenance system for the sealed cabin of a spacecraft. Bottles and pipeline components. The airtight cabin of the spacecraft is equipped with a product inflation port and a product pressure measurement port. Th...
