Estimating the term…
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.
A method for diagnosing technical devices, especially pumps and valves, that are disposed within an industrial installation used in the processing industry, with disturbance variables that affect the devices and influence the service life thereof being detected by means of sensory technology, with the data of said disturbance variables being processed in a simulative manner in order to determine the expected service life of each device wherein in an expert unit various maintenance instructions are stored, with said maintenance instructions being output together with the expected remaining trouble-free operating time of the industrial installation when a lower service life limit of one or more devices is reached.
A device for diagnosis of technical devices, especially of pumps and valves, that are disposed within an industrial installation used in the processing industry with sensors for detecting disturbance variables that affect the devices and influence the service life thereof, with the data of said disturbance variables being processed by a simulation unit containing a stored device model in order to determine the expected service life of each device, wherein furthermore an expert unit containing stored servicing instructions is provided that outputs an associated maintenance instruction together with the expected remaining trouble-free operating time of the industrial installation via a central display unit when a lower service life limit of one or more devices is reached.
