3 Terms and Definitions
The terms and definitions defined in GB/T 20921 and the following apply to this document:
3:1
Reciprocating piston compressor monitoring reciprocatingcompressormonitoring
Through the data acquisition equipment, the key phase, vibration, offset, temperature, pressure and other information of the reciprocating piston compressor are collected online and offline:
After a series of data processing such as filtering, amplification and feature extraction, the characteristic parameters of the operating state of the reciprocating piston compressor are obtained, which are stored in the data
Processing and storage equipment to monitor and analyze the running state of the reciprocating piston compressor:
3:2
The whole cycle data acquisition the whole cycle data acquisition
The data is collected according to the periodic operation of the reciprocating piston compressor, and the length of the data corresponds to the operation of one or more reciprocating piston compressors:
cycle:
3:3
keyphase monitoring keyphasemonitoring
Monitor reciprocating piston compressor crank angle and
Reference azimuth signal for each cylinder piston position:
3:4
Synchronous data acquisition of all channels synchronousdataacquisitionofalchannels
All acquisition channels of a single or multiple data acquisition devices complete data acquisition synchronously according to unified instructions:
3:5
continuous data acquisition continuousdataacquisition
According to a certain sampling rate, data collection is carried out continuously and without omission, so as to realize the continuous working cycle of vibration, offset and rotation speed of the reciprocating piston compressor:
