Title:
LIFE DETERMINATION SYSTEM FOR HYDRAULIC PUMP
Document Type and Number:
Japanese Patent JP2023105968
Kind Code:
A
Abstract:
To provide a life determination system for a hydraulic pump that can accurately grasp its residual life.SOLUTION: A life determination system 4 for a hydraulic pump 11 to be driven by a motor 2 includes a pump controller 5. Every time a predetermined period elapses, the pump controller 5 calculates equivalent operation time of the hydraulic pump 11 in the predetermined period on the basis of actual operation time of the motor 2, transition of rotation speed of the motor 2, transition of discharge pressure of the hydraulic pump 11, and transition of temperature of hydraulic fluid in the predetermined time.SELECTED DRAWING: Figure 1
