| 20100293933 | METHOD FOR AUTOMATICALLY DETERMINING THE CONDITION OF A HYDRAULIC AGGREGATE - A hydraulic aggregate for supplying a hydraulic cylinder in consecutive load strokes is monitored for its working load in order to determine the condition of the aggregate automatically. For this purpose, the time integral of the pressure is determined for each load stroke. The pressure and duration are processed into a characteristic number which indicates the wear. This makes it possible to diagnose the condition of the hydraulic aggregate at any time. | 11-25-2010 |
