Embodiment Construction
[0070] When working in oil wells, the special oil pump for the intelligent oil production system is lowered to the design depth, and a special intelligent controller and frequency converter are installed in the original control cabinet. The intelligent controller is designed with an electrical parameter acquisition device to test and collect the running time of the motor in real time. The active power of the intelligent controller is written with embedded software, which calculates the power map and the depth of the dynamic liquid surface of the pumping unit through the software, and based on the depth of the dynamic liquid surface, when the submergence of the oil well reaches a reasonable range, the intelligent The program controls the forward and reverse rotation of the motor at low speed through the frequency converter to realize the swing of the crankshaft and provide waiting time for the oil pump to be fully charged. At the same time, it realizes the remote transmission and...
