The invention discloses a method and device for state monitoring of a centrifugal compressor unit, and relates to the technical field of centrifugal compressor units. According to the method and device for state monitoring of the centrifugal compressor unit, the problem that the targeted monitoring cannot be carried out caused by the difficult screening of effective data during monitoring a stateof the centrifugal compressor unit can be solved. The method comprises the steps of dividing working stages of the centrifugal compressor unit according to the type of a prime motor of the centrifugalcompressor unit; configuring a corresponding sampling period for each working stage; and recording the state monitoring data of the centrifugal compressor unit in each working stage by using the sampling periods so as to achieve the state monitoring of the centrifugal compressor unit. The method is suitable for monitoring the state of the centrifugal compressor unit.
Description
technical field [0001] The present application relates to the technical field of centrifugal compressor units, in particular to a method and device for state monitoring of centrifugal compressor units. Background technique [0002] A centrifugal compressor unit usually includes a prime mover, a transmission and a centrifugal compressor, and its status monitoring signals include bearing temperature signals, bearing vibration signals (including double frequency signals and double frequency signals), bearing displacement signals and unit key phase signals, etc. In summary, all the above signals can be collectively referred to as the shafting signal of the centrifugal compressor unit. When the centrifugal compressor unit is running or starts and stops, the condition monitoring system as the centrifugal compressor unit should record at any time, so as to diagnose and analyze the condition of the unit. [0003] The traditional method of monitoring data of centrifugal compressor u...
