Abstract

The invention belongs to the technical field of vortex reducer test design, and particularly relates to a vortex reducer test device. The device is a special test device for the vortex reducer, the working state of the vortex reducer can be simulated, can be prevented from being directly subjected to performance tests on a whole machine so as to reduce the safety risk of the test, secondary damageto a large number of parts caused by faults of the vortex reducer in the test is prevented, a lead hole is arranged in the vortex reducer, after a test lead is led out from an air inlet cavity and then is connected with an electric conductor, and the air bleed efficiency of the vortex reducer can be accurately measured; and in addition, the vortex reducer testing device does not have the limitation of weight indexes, and has extremely containment of the faults of the vortex reducer, an experiment table and auxiliary related experimental equipment cannot be further damaged.

Description

technical field [0001] The application belongs to the technical field of vortex reducer test design, and in particular relates to a vortex reducer test device. Background technique [0002] When the aero-engine is working, the bleed air structure is usually used to bleed air from the compressor rotor for sealing or cooling of other components. In practical applications, a vortex reducer is often installed in the bleed air structure to reduce the loss of bleed air. The performance test of the newly designed vortex reducer needs to be carried out before application. At present, the performance test of the newly designed vortex reducer is mostly designed to be carried out on the whole machine. This technical solution has the following defects: [0003] (1) The newly designed vortex reducer has a large and unpredictable safety risk when it is directly installed on the whole machine without component reliability test; [0004] (2) It is difficult to test the lead wire, and it is...
