Methods for detecting abnormalities in impact treatment devices and nozzles

Abstract

The impact treatment device includes: a storage section for storing the spray material; a nozzle for spraying the spray material together with compressed air by negative pressure suction; a transport path for transporting the spray material from the storage section to the nozzle; a compressed air supply section for supplying compressed air to the nozzle; a pressure gauge for detecting the pressure within the transport path; and an anomaly detection section for detecting anomalies in the nozzle based on the pressure gauge readings.
