Abstract

The invention discloses a testing rack and an all-condition sealing testing device. The testing rack comprises a rotor, a bearing used for bearing the rotor, a bearing base and a supporting base. A high-pressure cavity is formed inside the testing rack, the high-pressure cavity is communicated with an air exhaust cavity and an air exhaust channel respectively, the air exhaust channel is communicated with a cold air channel, and a hot air sealing ring is arranged between the air exhaust channel and the rotor for isolation. High-temperature high-pressure air can be led into the testing rack, real-time working conditions of an aero-engine sealing device can be simulated, normal operation of parts such as the rotor can be guaranteed, the actual situations of the sealing device can be really reflected and correct judgment of the probability, the reliability and the durability of use of the sealing device on an aero-engine can be made.

Description

technical field [0001] The invention relates to a test device, in particular to a test bench and a full working condition sealing test device. Background technique [0002] At present, the sealing devices commonly used in aero-engines are usually designed based on experience, verified by static and dynamic tests, and necessary modifications are made to their structures according to the test results. For the design of some new sealing devices, they are based on new theories, and a large number of experiments are needed to verify whether the theoretical analysis and design are correct. Whether the test result is correct or not is directly related to the success or failure of the design of the sealing device. [0003] With the improvement of the performance of the aero-engine, the cycle parameters (pressure, temperature) increase, the rotor speed increases, the working conditions of the seal are deteriorating day by day, and the problems caused by the sealing device are becomi...
