Description This dataset contains operational data recorded from centrifugal pumps that supply demineralized water to the boilers of a heating plant. The plant provides the steam required by the research test facilities at CIRA (Italian Aerospace Research Centre). The dataset includes eigth CSV files, each representing data collected from a specific centrifugal pump during a single operational day. Filenames uniquely identify both the pump unit (A, B, or C) and the corresponding day of operation. For example, the file A_2024-04-10.csv contains the recorded data for centrifugal pump A on April 10, 2024. At the time of writing, the dataset includes records from three distinct operational days, each covering a different time span. Note: Data for pump C is not available for October 30, 2024, as the pump was turned off on that day. Each CSV file contains 11 columns: one for the timestamp and ten for measured values. The column headers include the following names, as listed in the following Table, where the prefix X represents the centrifugal pump unit label (e.g., A, B, or C): Column Name Description Unit of Measure Timestamp temporal timestamp indicating when the measurement was taken, formatted as YYYY-MM-DD hh:mm:ss - X_ACR_Mot.PV vibrational velocity measured by the motor accelerometer m/s X_ACR_Mot.SV peak value measured by the motor accelerometer m/s2 X_ACR_Mot.TV contact temperature of the motor accelerometer °C X_ACR_Pmp.PV vibrational velocity measured by the pump accelerometer m/s X_ACR_Pmp.SV peak value measured by the pump accelerometer m/s2 X_ACR_Pmp.TV contact temperature of the pump accelerometer °C X_Temp.SV motor casing temperature °C X_Pres.SV outlet fluid pressure from the pump bar Barometer atmospheric pressure mbar Temperature ambient temperature °C The nameplate data of the motor and pump are reported in the following table: Electric Motor Power Shaft Speed Voltage Poles Frame Size (H) 110 kW 2980 rpm 400 V 2 315 mm Mechanical Multistage Pump Power Flow Rate Pump Head Max Pressure N° of Impellers 10 kW 45 m3/h 450 m 40 bar 7 For any inquiries or issues regarding the dataset, please contact a.martone@cira.it and/or g.zazzaro@cira.it Data were collected as part of the SACIP (SAlus CIra Plant) project, funded by the Italian PRORA.
