Publication number: 20240393225Abstract: Provided is a system for accurately calculating the degree of clogging of a filter with reduced amount of required data. The system includes a controller. The controller stores a judgment permission condition including that the flow rate of hydraulic fluid passing through a filter exceeds a predetermined flow rate threshold, and calculates: a judgment-permissible time, which is an integrated value of time in which the judgment permission condition is satisfied; and a judgment target time, which is an integrated value of time in which the judgment permission condition is satisfied and the differential pressure across the filter exceeds a predetermined differential pressure threshold. The controller calculates the degree of clogging of the filter on the basis of a comparison between the judgment permission time and the judgment target time.Type: ApplicationFiled: October 11, 2022Publication date: November 28, 2024Applicant: KOBELCO CONSTRUCTION MACHINERY CO., LTD.Inventors: Kosuke YANAGIBASHI, Kenichi TERAUCHI, Tatsuya TSUCHIHARA, Kazuhiro IWASAKI, Tomohiro NAKAGAWA, Ryo HAMAMOTO
