Technical Field
The utility model relates to the technical field of air pressure tests of air separation towers, in particular to an air pressure test device.
Background
The pressure test of the air separation tower mainly adopts two methods of gas cylinder pressure test and pipeline pressure test. As the tower is increasingly enlarged, if a single gas cylinder is adopted for pressure test, the gas cylinder is limited by the gas quantity, and the gas cylinder needs to be repeatedly replaced until the pressure meets the test requirement, so that the working efficiency is greatly reduced; if the pipeline is adopted for pressure test, the pipeline is required to be combined with the air storage tank, the cost is additionally increased when the air storage tank is manufactured, and the pressure test medium is single. If the pipeline length is too long, pressure loss exists in the middle of the pipeline and cannot meet the test pressure requirement, and potential safety hazards exist.
