PUMP CONTROL DEVICE AND PUMP CONTROL METHOD
PROBLEM TO BE SOLVED: To provide a pump control device capable of changing setting of a pump flow rate, and to provide a pump control method.SOLUTION: A controller 34 acquires a total sum value and the largest value of a flow rate requested from each hydraulic actuator. The controller 34 sets a pump flow rate command value based on a value to which a value obtained by multiplying the largest value by a specific gain of a difference between the total sum value and the largest value is added. Setting of a pump flow rate can be readily changed by changing the gain value.SELECTED DRAWING: Figure 1
【課題】ポンプ流量の設定を変更可能なポンプ制御装置およびポンプ制御方法を提供する。【解決手段】コントローラ34は、各油圧アクチュエータからの要求流量の総和値と最大値とを求める。コントローラ34は、最大値に対して、総和値と最大値との差の所定のゲインを乗じた値を加算した値に基いてポンプ流量指令値を設定する。ゲインの値を変えることによりポンプ流量の設定を容易に変更可能となる。【選択図】図１
