Description

ji - число зон возмущени  потока в 1-й ступени в момент их зарождени .ji is the number of zones of flow perturbation in the 1st stage at the time of their nucleation.

2. Устройство дл  прогнозировани  неустойчивых режимов работы многоступенчатого компрессора, содержащее размещенные в корпусе компрессора по ходу вращени  ротора приемник статического давлени  и приемник полного давлени , подключенные к ним датчик разности давлений и преобразователь сигнала, отличающеес  тем. что, с целью повышени  надежности прогнозировани , устройство снабжено дополнительными приемниками2. A device for predicting the unstable operating conditions of a multi-stage compressor, comprising a static pressure receiver and a full pressure receiver located in the compressor housing along the rotor rotation, and a differential pressure sensor and a signal converter connected thereto, characterized in that. that, in order to increase the reliability of forecasting, the device is equipped with additional receivers
