METHOD FOR DIAGNOSING A DIAPHRAGM VALVE, AND DIAGNOSIS SYSTEM FOR A DIAPHRAGM VALVE

摘要

The invention relates to a method for diagnosing a diaphragm valve (10) comprising the following steps: a) providing at least one first quantity that characterizes a valve diaphragm (14), at least one second quantity that characterizes the diaphragm valve (10), and at least one third quantity that characterizes operation of the diaphragm valve (10) to a determination device (46); determining a quantity that characterizes a current state of the valve diaphragm (14), in particular a current wear, from the first, second, and third quantities by means of the determination device (46) by using at least one algorithm.
