Method for measuring pressure of turbine chamber of marine gas turbine

Abstract

The invention aims to provide a method for measuring the pressure of a turbine chamber of a marine gas turbine. The method comprises the following steps of selecting a turbine chamber which needs to be subjected to pressure measurement; determining the arrangement positions and the number of to-be-measured turbine chamber measuring points; designing a pressure measuring tube lead path; according to the lead planning path, the turbine case and the turbine guide blade being subjected to supplementary machining; according to the lead planning path, pressure measuring tube installation and lead being completed; the pressure measuring pipe being fixed along the way, and the casing being sealed. The method is advantaged in that the survival rate of the pressure measuring points is improved, and pressure parameters of the turbine part cavity of the marine gas turbine can be accurately obtained in real time. Key data support can be provided for gas turbine part design, mutual matching of a turbine and a gas compressor part and whole machine axial force adjustment. The method is not limited to the measurement of the pressure of the turbine component chamber of a marine gas turbine, but also suitable for measurement of the pressure of the turbine component chambers of industrial gas turbines, aero-engines and heavy-duty gas turbines.

Description

technical field [0001] The invention relates to a pressure measurement method, in particular to a gas turbine turbine pressure measurement method. Background technique [0002] Because gas turbines have the advantages of high power density, compact structure, light weight, convenient maintenance, and high reliability, more and more ships have chosen gas turbines as the main power plant in the past ten years. With the continuous increase of the ship's load capacity, the demand for new high-efficiency and high-power gas turbines is becoming more and more intense. The research and development of gas turbines is an iterative process of design and testing, and the ability to test and test is an essential part of the development of advanced high-power gas turbines. [0003] The whole process test of gas turbine is an important means to fully grasp the component performance, component matching and overall performance under the whole machine condition. Through the measurement of t...
