Embodiment 1

[0045] The intake air flow nozzle assembly provided in this embodiment is used in an intake air flow measuring device.

[0046] See Figure 1 to Figure 7 And combine Picture 8 As shown, the intake air flow nozzle assembly in this embodiment includes a plurality of nozzle flow meters 6 and a connecting seat with a plurality of connecting through holes 22 arranged in an array, and the nozzle flow meters 6 are arranged in the connecting through holes in one-to-one correspondence. Within 22. The connecting seat provided with the connecting through hole 22 provides support and fixation for each nozzle flowmeter 6, thereby combining a plurality of nozzle flowmeters 6 to form an intake flow nozzle assembly.

[0047] A predetermined number of nozzle flowmeters 6 evenly arranged relative to the connecting seat among the plurality of nozzle flowmeters 6 can be opened at the same time to reach the predetermined intake flow rate through the intake flow measurement range of the intake flow no...

Abstract

The invention relates to the technical field of gas turbine air inlet flow testing equipment, in particular to an air inlet flow nozzle assembly and an air inlet flow measuring device. The air inlet flow nozzle assembly comprises a plurality of nozzle flowmeters and a connecting base with a plurality of connecting through holes distributed in an array mode, and the nozzle flowmeters are arranged in the connecting through holes in a one-to-one correspondence mode. A preset number of nozzle flowmeters which are uniformly distributed relative to the connecting seat in the plurality of nozzle flowmeters can be simultaneously started, so that the measurement upper limit of the air inlet flow nozzle assembly reaches the preset air inlet flow. According to the air inlet flow nozzle assembly and the air inlet flow measuring device, the preset number of nozzle flowmeters are combined, so that the air inlet flow nozzle assembly and the air inlet flow measuring device can be suitable for air inlet flow measurement during tests of gas turbines of various models and power levels, and the flexibility is very high.

Description

Technical field [0001] The invention relates to the technical field of gas turbine intake flow measurement equipment, and in particular to an intake flow nozzle assembly and an intake flow measurement device. Background technique [0002] Accurate measurement of turbine intake air flow is essential for turbine performance calculation and compressor surge analysis. In the conventional turbine test bench, a double twisted-wire flow tube is connected to the intake duct for the measurement test of the intake flow. [0003] In the related art, since the measurement accuracy of the flow tube requires the intake Mach number, the excessive size of the flow tube will cause the intake Mach number to be inapplicable. Therefore, it is necessary to use a smaller size flow tube to measure the ground heavy turbine. However, the smaller size of the flow tube means that it can only measure the intake flow in a small range. When the required intake flow of the turbine to be tested exceeds the measu...
