Zusammenfassung: | The invention discloses a method and a device for testing the influence of a whole-circle straight-through type labyrinth sealing gap on the leakage rate, and the method comprises the steps: designing an equivalent test piece, enabling the sealing gap to be conveniently and equivalently adjusted under the condition of not replacing the test piece, and carrying out the equivalent testing of the influence of different sealing gaps on the labyrinth leakage rate, the testing device comprises a base, a base cover, a movable seat, a gap adjusting device, an air supply device, a pressure sensor and a temperature sensor, can provide an experimental environment for a leakage test, and can conveniently adjust a sealing gap. According to the method and the device for testing the influence of the whole-circle straight-through type labyrinth seal clearance on the leakage rate, the equivalent test of the influence of the whole-circle straight-through type labyrinth seal clearance on the leakage rate can be realized.
