TROUBLE DIAGNOSING APPARATUS FOR HYDRAULIC PUMP, CONSTRUCTION MACHINE COMPRISING TROUBLE DIAGNOSING APPARATUS, TROUBLE DIAGNOSING METHOD AND TROUBLE DIAGNOSING PROGRAM
To provide a trouble diagnosing apparatus for a hydraulic pump by a calculation method reduced in calculation load with using a less number of sensor devices without affected by a surrounding environment such as atmospheric pressure fluctuations due to weather or altitude.SOLUTION: A trouble diagnosing apparatus 65 comprises a time-series data storage section 651 that stores an in-case pressure of a hydraulic pump as time-series pressure data chronologically, a variation calculating section 652 that calculates a variation of section data obtained by dividing the time-series pressure data into a plurality of sections having constant widths, and an abnormality determining section 653 that determines an abnormality of the hydraulic pump based on a magnitude of the variation.SELECTED DRAWING: Figure 2
【課題】天候や標高による大気圧変動などの周囲環境に影響されることなく、少ないセンサ機器で、計算負荷の少ない計算手法によって、油圧ポンプの故障診断装置を提供する。【解決手段】故障診断装置６５は、油圧ポンプのケース内の圧力を時系列に従って時系列圧力データとして記憶する時系列データ記憶部６５１と、時系列圧力データを一定幅の複数の区間に分割して得られる区間データのバラツキを算出するバラツキ算出部６５２と、前記バラツキの大きさに基づいて前記油圧ポンプの異常を判定する異常判定部６５３を備える。【選択図】図２
