Journal Bearing Fault Detection in a Vertical Motor-Pump Testbed

The dataset contains synchronized multiphysics sensor data acquired from a vertical motor-pump testbed. The measured signals include vibration, acoustic signals, temperature, oil pressure, shaft displacement, three-phase motor current, and RPM, sampled at 25.6 kHz. Sensors were installed around Journal Bearings A and B, while bearing fault conditions were introduced at Journal Bearing B using different clearance levels. The dataset includes healthy and fault conditions under fixed-speed and ramp-speed operation. More detailed information on the testbed, sensor configuration, and experimental conditions is available in the "Data in Brief" article, “Multiphysics Sensor Dataset for Journal Bearing Fault Detection in a Vertical Motor-Pump Testbed for SMR RCP Monitoring.”本数据集包含采集自立式电机泵试验台的同步多物理场传感器实测数据。实测信号涵盖振动、声学信号、温度、油压、轴位移、三相电机电流及转速（RPM），采样率为25.6 kHz。传感器布置于轴颈轴承（Journal Bearing）A与B的周边，同时通过调整不同间隙量在轴颈轴承B处引入轴承故障工况。本数据集覆盖定速及斜坡调速运行模式下的健康与故障两类工况。 有关试验台、传感器配置及实验条件的详细信息，可查阅发表于《数据简报（Data in Brief）》的文章《用于SMR RCP监测的立式电机泵试验台轴颈轴承故障检测多物理场传感器数据集》。
