Vibration Analysis and Improvement of the Pitch and Rotation Hydraulic Station of the Ship Loader
Aiming at the vibration problem of the ship loader pitch and rotation hydraulic station,an online monitoring system for the ship loader pitch and rotation hydraulic station is designed based on the theory of vibration time-domain analysis.By collecting and calculating the acceleration signals of the oil pump and oil tank,the vibration signal is visualized in the form of a spectrogram.The hydraulic impact of the low-pressure and high-flow relief valve is calculated and the vibration waveform is solved,which can eliminate the influence of the hydraulic shock of the oil supply relief valve on the system.Taking vibration reduction measures for the drive motor and oil tank of the hydraulic station can enhance the overall reliability of the hydraulic station system.
