Abstract

Disclosed is a method for diagnosing technical devices, especially pumps and valves, which are arranged within an installation used in the processing industry. According to said method, disturbance variables that affect the devices and influence the service life thereof are detected by means of sensory technology while the data of said disturbance variables is processed in a simulative manner in order to determine the expected service life of each device. Various maintenance instructions which are output along with the expected remaining trouble-free operating time of the industrial installation when a lower service life threshold value of one or several devices has been reached are stored in an expert unit.
