Abstract

The invention discloses a modular multifunctional gas turbine test bench, which at least comprises a gear box, a compressor installation station, a turbine installation station and a combustion chamber. The gear box includes at least one high speed shaft and at least one low speed shaft; one end of the high speed shaft is used for connecting a jiggering motor and the other end is connected with atesting compressor; the low speed shaft is used for connecting a starting power source or driving power source or load. The compressor installation station is used for installing a testing compressorand is provided with an intake system and an intake chamber. The turbine installation station is used for installing a turbine and is provided with an exhaust cylinder, an exhaust chamber and an exhaust system. The combustion chamber is provided with a flange interface for connecting a nausea board flange or a combustion assembly and at least includes a flame tube and a fuel nozzle. Therefore, thecompressor test, the whole machine no-load test, the whole machine full-load test, and the subsequent test power station operation test are carried out by the same test bench.

Description

technical field [0001] The invention relates to a test bench for a gas turbine test, which is used for realizing a compressor test, a complete machine no-load test, a complete machine full-load test, and a subsequent test power station operation test on the same test stand. Background technique [0002] Experimental research is an important method for analyzing the flow structure and performance of turbomachinery. It can comprehensively consider various factors affecting the flow, and the results are objective and reliable. The compressor test can be used to guide, research and design the compressor, and identify the effectiveness of the target compressor; after the gas turbine is assembled, it is necessary to conduct a complete machine no-load test on the gas turbine, the main purpose of which is to test the operation, vibration and aerodynamic performance of the unit ;For newly developed models, it is necessary to conduct a full-speed and full-load test to comprehensively ...
