Embodiment Construction

[0011] first reference figure 1 , the dynamic pressure sensor 1 collects the pressure signal at the outlet of the compression machinery and provides it to the forecast and regulation analog circuit, and the DC power supply 2 is used to provide power for the entire device. The preamplifier analog circuit 3 amplifies the millivolt-level voltage signal of the sensor into a dynamic signal in the range of 2.5 volts, the purpose of which is to improve the resolution of the dynamic signal, and then the low-pass filter analog circuit 4 converts the dynamic signal into the dynamic signal related to the surge precursor The low-frequency signal is extracted to lay the foundation for the analysis of the subsequent analog data module. Then, the FFT analysis DSP module 5 performs Fourier online analysis on the dynamic signal, captures the frequency information related to the surge precursor, and provides the analog output for the switch analog circuit and sawtooth wave. The module provides ...

Description

technical field [0001] The invention relates to a compression system surge online prediction and self-adaptive adjustment method and device. Background technique [0002] In the field of the existing fluid compression machinery system, the surge phenomenon existing in the operation process of the fluid compression machinery endangers the operation safety of the system, and once it occurs, it will cause a catastrophic accident. This kind of strong fluid vibration will lead to the damage of important components of the compressor (rotor, axial thrust, stator, diffuser), which is the main hazard to the stable operation of the compression system, and will cause the consequences of machine crash and death in severe cases. For nearly half a century, the surge phenomenon of the compression system has been a difficult topic of general concern to the research and designers of turbomachinery. At present, the mature technology is to reserve enough surge reserve in design and operation ...
