Изобретение относится к области энергомашиностроения. Способ заключается в измерении пульсаций неподвижным датчиком, установленным в зоне лопаток рабочего колеса на корпусе турбомашины. О моменте возникновения автоколебаний судят по появлению двух частот, близких по величине и симметрично расположенных справа и слева относительно частоты следования лопаток. 3 ил.The invention relates to the field of power engineering. The method consists in measuring pulsations with a fixed sensor installed in the area of the impeller blades on the turbomachine body. About the moment of occurrence of self-oscillations is judged by the appearance of two frequencies, close in size and symmetrically located on the right and left relative to the frequency of the blades. 3 il.
