  • Publication number: 20240393225
    Abstract: 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.

    Abstract: The film is formed using one of two film-forming materials. The first film-forming material contains: particles containing a crystal phase of a rare earth element fluoride; particles containing a crystal phase of a rare earth element oxide; and particles containing a crystal phase of a rare earth element ammonium fluoride double salt. The second film-forming material contains: particles containing a crystal phase of a rare earth element fluoride; and particles containing a crystal phase of a rare earth element oxide and a crystal phase of a rare earth element ammonium fluoride double salt. If a spray coated film is to be formed by means of thermal spraying using this film-forming material or film-forming slurry in particular, it is possible to form a rare earth element oxyfluoride spray coated film without the need for excessive heat.
