摘要
Abstract
To investigate the fault characteristics of vertical submersible pumps under bearing wear conditions,a multi-source condition monitoring system was established,and bearing fault samples were processed and selected.Fault experiments were conducted to collect voltage,current,vibration,and temperature signals of the submersible pump under various operating conditions.The time-domain and frequency-domain characteristics of these signals were then analyzed.Typical fault samples were created by customizing bearings with increasing clearance and selecting service-failed bearings.A com-prehensive testing platform was established,which included an electrical signal monitoring system above ground and a mechanical signal acquisition device underground.The experimental system syn-chronously collected multi-source signals such as three-phase voltage and current,radial and axial vi-brations,motor temperature,and outlet pressure,covering a flow range of 20%to 160%of the rated capacity.The results indicate that the characteristics of the customized faulty bearings and the service-failed bearings are similar across various signals.Notably,the vibration signal characteristics are pro-nounced,with an increase in the peak-to-peak value of the vibrations.The amplitude of the radial vi-bration at the rotational frequency significantly increases,while the axial vibration shows an increase in the harmonics of the rotational frequency.In terms of the current signal,there is a modulation effect observed at four times the rotational frequency.关键词
