Description

Technical Field

[0001] The utility model relates to the technical field of tire testing devices, in particular to an aviation tire water pressure bursting testing device. Background Art

[0002] A tire hydraulic burst tester is a specialized device used to test a tire's maximum load-bearing capacity, or burst pressure. It applies pressure to the tire chamber to simulate the pressure conditions a tire might encounter under different road and load conditions. Prior Art Authorization Publication No. CN202994592U proposes an aircraft tire hydraulic burst tester, which includes a hub for mounting an aircraft tire. The hub comprises a central rim and two end flanges. One end flange of the hub is a movable flange that fits over the corresponding end of the rim. A limiting mechanism is provided on the rim outside the movable flange, and a sealing mechanism is provided between the mating surfaces of the movable flange and the rim. The rim has a water inlet for filling the aircraft tire. The limiting mechanism is a retaining ring that snaps into a corresponding slot on the rim, and the sealing mechanism is a sealing ring that snaps into a corresponding sealing slot on the rim. However, the tire itself acts as a sealed air cavity, making it difficult for air to escape from within. If there is unexpelled air inside the tire, the air expansion rate is high, and it is difficult to obtain a stable pressure increase rate during the water injection process. The water injection test is unstable, which affects the accuracy of the bursting pressure value and the test effectiveness is low. The air inside the tire is compressed by the injected water, generating kinetic energy, which produces a large impact force during the explosion, posing a safety hazard. Utility Model Content
