Title:
CLOGGING CALCULATION SYSTEM, CLOGGING CALCULATION METHOD, AND CLOGGING CALCULATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/068115
Kind Code:
A1
Abstract:
Provided is a system for accurately calculating the degree of clogging of a filter while limiting the amount of data required. This system comprises a controller (60). The controller (60) stores a determination-permissible condition, which includes the flow of hydraulic fluid through a filter (45) exceeding a prescribed flow threshold, and calculates: a determination-permissible time, which is the added-up value of times when the determination-permissible condition is satisfied; and a determination target time, which is the added-up value of times when the determination-permissible condition is satisfied and the differential pressure of the filter (45) exceeds a prescribed differential pressure threshold. The controller (60) calculates the degree of clogging of the filter (45) on the basis of a comparison between the determination-permissible time and the determination target time.
