METHOD FOR MONITORING MACHINES WITH ROTATING SHAFTS |
摘要 |
The invention relates to a method for detecting rubbing and/or contact points on machines with rotating parts. The rotating parts form an electrical coaxial system with respect to the stationary parts of such a machine, in which system electrical voltage pulses are propagated at a characteristic speed because of the small distance between the rotating and the stationary part. Short electrical voltage pulses and/or continuous alternating voltage signals are applied between the rotating part and the stationary part, an electrical connection occurring between the rotating and the stationary part at a rubbing and/or contact point. In order to locate this rubbing and/or contact point as a point of electrical discontinuity, the period of time until the reflected pulses arrive is measured along the path of propagation of the electrical voltage pulses and/or of the continuous alternating voltage signals. |
