Description

technical field

[0001] The invention relates to a device for simulating and analyzing the vibration of a gas turbine compressor, capable of simulating various possible vibration factors of a gas turbine compressor, and analyzing the vibration through feature extraction, in particular to a gas turbine compressor vibration simulation test tower. Background technique

[0002] The commonly used vibration simulation platform is the most direct and important means for vibration and learning of commonly used rotating parts, and it is one of the important test equipment for the diagnosis and research of rotating parts. Through electric dragging, the rotor of the test piece is dragged to various speeds, and the vibration monitoring equipment is used to study and analyze the vibration characteristics of the rotating parts at various speeds. However, there are many reasons for the vibration of the gas turbine compressor rotor. The usual vibration simulation platform can only simulate ...

Embodiment 1

[0032] exist figure 1 Among them, the SFC variable frequency starter 1 outputs variable frequency alternating current to the starter motor 2, and the starter motor 2 and the test compressor 4 are coaxially connected through a coupling 41 and well aligned. At the same time, the test compressor 4 is well dynamically balanced. Plant influences due to rotor unbalance and rotor misalignment are thereby excluded. The exhaust port of the intake component 3 is connected to the inlet of the test compressor 2 . The exhaust port of the test compressor 4 is connected to the inlet of the exhaust component. In the test, the starter motor 2 driven by the SFC variable frequency starter 1 can run stably at any speed between 0 and 10000 rpm. Such as figure 2 As shown, the test compressor 4 has three-stage compressor air extraction pipelines, the three air extraction pipelines are respectively 461, 462, and 463, and each air extraction pipeline is provided with an air extraction valve, and ...
