Detection system and method for engine gas turbine starter

Abstract

The invention discloses a detection system and method for an engine gas turbine starter. The system comprises a control unit which is used for receiving a detection signal and transmitting the detection signal to a display terminal, a rotating speed detection module which is used for detecting the rotating speed of an air compressor and the rotating speed of a free turbine through an external rotating speed sensor to obtain rotating speed signals of the free turbine and the air compressor, a pressure detection module which is used for detecting the pressure of a lubricating oil through a pressure detector to obtain a pressure signal of the lubricating oil, a temperature detection module which is used for detecting the exhaust temperature of an engine through a temperature detector to obtain a temperature signal, a vibration detection module which is used for detecting the engine through a vibration sensor to obtain a vibration signal, and a microswitch detection module which is used for detecting whether a microswitch coil is normally switched on or not by supplying power to the microswitch coil so as to obtain a switching signal. The system is advantaged in that key parameters such as pressure, rotating speed, temperature, vibration and the like of the gas turbine starter are monitored, and the gas turbine starter has data recording and storing functions so as to diagnose a technical performance state of the gas turbine starter.

Description

technical field [0001] The invention relates to the field of intelligent control and intelligent detection, in particular to a detection system and method for an engine gas turbine starter. Background technique [0002] The gas turbine starter is an important component of the aeroengine starting system. When the engine is started, the turboshaft gas turbine starter drives the high and low pressure rotors of the engine to rotate, and cooperates with the engine accessories to achieve engine ignition. At present, when a certain type of aero-engine is used in a high-altitude area, there is a phenomenon that the gas turbine starter cannot drive the engine to start. Therefore, it is necessary to monitor the working performance status of the gas turbine starter to judge its performance status. [0003] The current gas turbine starter control and detection system only detects fuel flow, turbine speed and pressure, the detection parameters are not comprehensive, and does not have dat...

Problems solved by technology

At present, when a certain type of aero-engine is used in a high-altitude area, there is a phenomenon that the gas turbine starter cannot drive the engine to start, so it is necessary to monitor the working performance status of the gas turbine starter to judge its performance status

[0003] The current gas turbine starter control and detection system only detects fuel flow, turbine speed and pressure, the detection parameters are not comprehensive, and does not have data storage and analysis functions. There is no relevant detection equipment to monitor the key parameters of the gas turbine starter , which is not conducive to judging its performance status
