VibraMap: A real-time tool for 3D Motion Characterization of shale shakers in production engineering applications
摘要
Shale shakers are critical equipment in various production engineering processes, particularly in solids control operations within the oil and gas industry. Optimizing their performance is crucial for operational efficiency, cost reduction, and environmental compliance. This paper introduces VibraMap, a computational tool developed for the real-time three-dimensional (3D) motion characterization of shale shakers. The system utilizes data from multiple low-cost MPU-9250 accelerometers strategically placed on the shaker basket. A robust methodology, employing the Differential Evolution algorithm, is used to fit an elliptical model to the acceleration data, allowing for the determination of key motion parameters, including frequency, G-factor, ellipse shape (major/minor axes, orientation), and phase angles. The VibraMap tool, featuring a C++ client for data acquisition and processing and a Python-based web server for real-time visualization, enables detailed analysis of the shaker’s dynamic behavior. Experimental validation on an industrial-scale Mongoose Pro Shaker demonstrated VibraMap’s capability to accurately identify the progressive elliptical motion characteristic of the equipment and quantify the significant impact of material load distribution on vibrational dynamics across the screen. The tool revealed variations in G-factor and motion amplitudes at different points of the basket, providing insights crucial for operational optimization and condition monitoring in production engineering contexts involving shale shakers. VibraMap represents a significant advancement in computer-aided engineering for monitoring and potentially controlling shale shaker operations, addressing the need for more detailed and real-time operational data.
