Problems solved by technology

[0002] Pressure probes are mostly used to measure the flow field of turbomachinery such as compressors, but in the process of aero-engine rain absorption characteristics test and gas turbine wet compression characteristics test, it is still difficult to accurately obtain the pressure value under the condition of gas-liquid two-phase existence. There is greater difficulty

Abstract

The invention aims to provide a steady-state pressure probe with a hydrophobic structure, which comprises a casing fixing table and a probe support rod, the casing fixing table is fixed at the tail end part of the probe support rod, the head end part of the probe support rod is provided with a hydrophobic part, and the hydrophobic part comprises a gas-water separator. The gas-water separator comprises an airflow baffle, a welding baffle and a total pressure gas inlet guide pipe, the total pressure gas inlet guide pipe is installed in the probe supporting rod through the welding baffle, the airflow baffle is installed at the front end of the total pressure gas inlet guide pipe, and an outlet of the total pressure gas inlet guide pipe is formed in the tail end of the total pressure gas inlet guide pipe; a total pressure air inlet is formed in the total pressure air inlet flow guide pipe behind the airflow baffle. A drain hole is formed in the probe supporting rod in front of the welding baffle. According to the invention, accurate measurement of a gas pressure value under the condition of inlet water in an aero-engine rain absorption test, a gas turbine inlet air humidification test and the like can be realized, water drops entering the probe can be rapidly evacuated, and high-precision measurement capability is realized.

Description

technical field [0001] The invention relates to a gas turbine measuring device, in particular to a gas turbine intake pressure measuring device. Background technique [0002] Pressure probes are mostly used to measure the flow field of impeller machinery such as compressors, but in the process of aero-engine rain absorption characteristics test and gas turbine wet compression characteristics test, it is still difficult to accurately obtain the pressure value under the condition of gas-liquid two-phase existence. There is greater difficulty. [0003] In view of the above problems, it is urgent to carry out innovative design based on the original pressure probe. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide accurate measurement of the gas pressure value under the condition of air intake water such as aeroengine rain absorption test and gas turbine intake humidification test, etc., and to quickly evacuate the water droplets entering the...
