Development of the FPR-5 intelligent dynamogram chart transmitter
The selection of the correct operating mode of sucker rod pumping units has a significant impact on the efficiency of oil production. In current practice, the inductive transducers used in traditional dynamometric measurements are technologically outdated; their element base is limited, their accuracy and speed are low, and the measurement method does not meet modern requirements. This complicates real-time control and diagnostics. Therefore, it is proposed to develop an intelligent dynamometer chart transmitter installed between the traverses to ensure accurate control and diagnostics in real-time. The proposed dynamometer chart transmitter records the force acting on the rod string with a piezoresistive strain gauge, and the displacement with a piezoelectric accelerometer. By combining a microprocessor, communication module, measurement electronics and accumulator into a single housing, a modern measurement system is obtained that possesses high accuracy, reliability and ease of application in industrial conditions.
