Problems solved by technology

The existing technology or system structure is relatively complex; or the measurement accuracy and range are limited; or the structure lacks the stable inlet pressure and flow field of the test piece; or does not have the functions of automatic measurement and automatic recording
At present, the air flow test device for measuring the turbine blades of gas turbines uses a fixture, and the connecting pipeline needs to be fixed in a specific test room, which is inconvenient to carry, takes up a lot of space, and the measurement range cannot be adjusted, and the measurement accuracy is not high. Time-consuming operation

Embodiment

[0065] Such as Figure 1 to Figure 8 The shown air flow test bench for gas turbine components includes air source processing equipment 9000 and a test bench body 1000 .

[0066] The air source treatment equipment 9000 is composed of an air compressor 101, an air storage tank 201, a primary filter 301, a freeze dryer 401, a medium filter 302, an adsorption dryer 402, and a high efficiency filter 303 in series. Wherein, the refrigerated dryer 401 and the adsorption dryer 402 discharge water into the water-repellent device 403 . The filtration accuracy of the primary filter 301 , the intermediate filter 302 , and the high efficiency filter 303 increases step by step, and the filtration accuracy of the outlet of the high efficiency filter 303 is 0.01 μm. The freeze dryer 401 controls the dew point temperature of the processed air at 2°C to 10°C, and the adsorption dryer 402 controls the dew point temperature of the processed air at -20°C to 0°C. After being compressed by the air...

Description

technical field [0001] The invention relates to the technical field of the structure and application of a flow test device, in particular to an air flow test bench and a test method for gas turbine components. Background technique [0002] According to the development requirements of gas turbine blade equipment, it is necessary to conduct an air flow test on the turbine blade, that is, to measure the air mass flow through the turbine blade under the test pressure, and to test the air flow of the blade by measuring the air flow through the gas film hole and flow channel of the turbine blade. Membrane hole conditions and internal flow channel processing conditions provide reference for selecting installed blades. This requires the use of air flow test equipment. The existing technology or system structure is relatively complex; or the measurement accuracy and range are limited; or the structure lacks the stable inlet pressure and flow field of the test piece; or does not have...
