METHOD FOR MONITORING A SPEED-CONTROLLED ELECTRIC MOTOR PUMP OF A HYDRAULIC CIRCUIT IN AN AIRCRAFT AND A HYDRAULIC SYSTEM FOR CARRYING OUT THE METHOD

摘要

The present invention relates to a method for monitoring a speed-controlled electric motor pump of a hydraulic circuit of an aircraft, wherein the electric motor pump comprises at least one electric motor having variable speed for driving the hydraulic pump and a hydraulic jacket cooling for cooling the electric motor pump is provided, through which the hydraulic medium conveyed by the pump flows, wherein the volume flow through the jacket cooling is detected for different motor speeds of the electric motor pump, in order to determine the volumetric efficiency of the pump.
