Tool for measuring air flow of swirler of combustion chamber of gas turbine

Abstract

The invention provides a tool for measuring the air flow of a swirler of a combustion chamber of a gas turbine, and relates to the technical field of gas turbine combustion chamber swirler air flow measurement. The tool for measuring the air flow of the swirler of the combustion chamber of the gas turbine comprises an isolation cabinet body, a gas collection tank, a swirler mounting plate and a pneumatic mounting module, a middle partition plate is fixedly connected to the interior of the isolation cabinet body, and the gas collection tank is fixedly connected to the inner bottom of the isolation cabinet body; the swirler mounting plate is fixedly connected to the upper surface of the gas collecting tank, and the upper surface of the gas collecting tank is located on the periphery of the swirler mounting plate and fixedly connected with the pneumatic mounting module. The invention aims to improve the air flow measurement precision of the swirler, reduce the problem of measurement value fluctuation caused by atmospheric environment disturbance, air inlet disturbance, pressure measurement disturbance and the like, and meanwhile, through the automatic pressing device, the assembly speed is improved, and meanwhile, the pretightening force after each time of installation is ensured to be consistent.

Description

technical field [0001] The invention relates to the technical field of air flow measurement of a vortex device in a combustion chamber of a gas turbine, in particular to a tool for measuring the air flow of a vortex device in a combustion chamber of a gas turbine. Background technique [0002] The vortexer is an important part of the aero-engine combustion chamber to control the combustion performance, and the effective opening area of ​​the vortexer is an important indicator of the performance of the part, so it needs to be measured. At present, the modern aero-engine combustor vortex is processed by casting method. After processing, the ventilation measurement is carried out in a simple tooling. Each part needs to measure the air flow at 3 to 5 different pressure points, so as to obtain the "pressure-flow" characteristic. Curve, and then get the effective opening area of ​​the vortex device. This value is then provided to the engine OEM along with the parts for selection ...
