Calibration system for variable capacity hydraulic pump
Providing high accuracy calibration of a pump control table when variable capacity of a hydraulic pump is controlled based on a pump control table representing the relationship between pump capacity and current command value. The calibration: acquires data by measuring pump pressure corresponding to each current command value while changing the current command value in a multi-step manner; obtains a factor K representing a relationship between pump pressure and pump flow rate; creates a first table representing a relationship between the factor K and pump pressure; creates a second table representing a relationship between current command value and pump pressure; creates a third table representing a relationship between pump flow rate and current command value according to factor K; and creates a pump control table representing a relationship between pump capacity and current command value through engine rotation speed during pump pressure measurement.
