Abstract

The invention discloses a compressor test device and relates to the technical field of engines. The compressor test device comprises a compressor, a case and a rotor driving shaft sleeve, and further comprises a drum shaft, a sealing disc and a driving shaft, wherein the sealing disc comprises a sealing cavity division part and a connecting part; labyrinth seals are arranged on the outer circumference of the sealing cavity division part and sealed with the inner chamber of the case; one end of the drum shaft is connected with the sealing cavity division part, and the other end of the drum shaft is connected with an outlet sealing disc of the compressor; the connecting part of the sealing disc is fixedly connected with one end of the rotor driving shaft sleeve, and the other end of the rotor driving shaft sleeve is connected with the driving shaft; and the sealing cavity division part divides a sealing cavity into a balance disc front cavity and a balance disc rear cavity. The compressor test device has the following beneficial effects: the sealing cavity division part divides the sealing cavity into the balance disc front cavity and the balance disc rear cavity, and the axial force born by the whole rotor system can be adjusted by controlling the pressure difference between the two cavities.

Description

Technical field [0001] The invention relates to the technical field of engines, in particular to a compressor test device. Background technique [0002] As one of the core components of the engine, the compressor is required to have a high boost ratio and high efficiency so that the engine can obtain higher thermal efficiency and unit power. In addition, a higher surge margin is required to adapt to the frequent maneuvering of the aircraft. For general-purpose core machines, versatility requirements must also be considered. Since the air flow in the compressor is a full three-dimensional, viscous, unsteady flow, its flow law is quite complicated. So far, people’s understanding of the gas flow mechanism in the turbomachine is still under continuous development and improvement. Since the years, computational fluid dynamics has made significant progress. In terms of turbomachinery, it has developed from two-dimensional inviscid analysis to full three-dimensional viscous flow analys...
