Abstract
There is higher fault probability for rod pumping system under the bad work conditions. Because of the large amount of sample and the long-time steady status, this paper proposes hierarchical fault diagnosis method. Fault distinguishing and fault identification are two stages in this method. In the second stage of the fault hierarchical diagnosis of rod pumping system based on surface dynamometer card, starting from fault mechanism, we propose search tree method in fault identification of rod pumping system on the basis of fault distinguish. In fault identification, combining statistical rule of normal samples and search tree based on fault principle and fault distinguish, search tree of rod pumping system is established to identify fault style including serious fault. Efficiency of this method is verified by identifying single fault and combined fault of rod pumping system accurately through typical fault dynamometer cards.
