In order to improve the efficiency of pumping unit,based on the analysis of the operation process of pumping unit and the working process of oil field,a design scheme for the efficiency test of pumping unit was presented by using the PLC control network and the industrial control configuration software CITECT.According to the characteristic of each work step of pumping unit,the data during the operation process were monitored,and the functions of data processing,system alarm,data storage,report output were achieved.Site implementation and experiments prove that the system has excellent human computer interface and high reliability.The system provides a convenient way for workers to set up the optimal configuration of pumping unit in accordance with the processing results.
