Abstract

The invention provides a turbine blade cooling effect test apparatus employing a gas turbine compressor to extract air. The turbine blade cooling effect test apparatus includes a turbine blade test system, a blade cooling air system, and a cooling water system. The turbine blade test system includes a mainstream inlet valve, an air inlet regulating valve, a metal expansion joint, a combustor, a turbine blade test section, an exhaust desuperheater, an exhaust butterfly valve, and a sound damping tower which are connected in order. The mainstream inlet valve extracts the compressor exhaust. The cooling air system comprises a cooling air inlet valve and a cooling air regulating valve. The cooling air inlet valve extracts the compressor exhaust. The cooling air regulating valve is connected to the turbine blade test section. The cooling water system includes a cooling tower. An outlet of the combustor and an inlet of the exhaust desuperheater are connected to the cooling tower through inflow pipes. An inlet and an outlet of the turbine blade test section are connected to the cooling tower through outflow pipes. The apparatus and the method provided by the invention can perform the cooling effect test of the turbine dynamic and stationary blades more accurately, more conveniently and more inexpensively.

Description

technical field [0001] The invention relates to a cooling effect test device and method of a turbine blade using a power station gas turbine compressor to extract air, and belongs to the technical field of gas turbines. Background technique [0002] Turbine blades are the key hot-end components of gas turbines. If the operating temperature of turbine blades exceeds the design value by 10°C, the life of turbine blades will be halved. As the cooling structure design technology of gas turbine blades is very complex, the newly developed turbine blade samples all need to carry out the verification test of the cooling effect of the turbine blades. The turbine blade cooling structure design can only be finalized when the cooling effect test of the turbine blade proves that the working temperature of the blade matrix does not exceed the working temperature of the nickel-based single crystal or directional crystallization blade. Turbine blade cooling effect test is a necessary link ...
