Modeling Residual Life of Main Line Pump from its Vibration Condition

[摘要] Pumping oil through pipelines is provided by Main Line Pumps (MLPs), whose stable operation is critical for general efficiency of the pipeline transportation. Vibration is one of the strongest adverse factors influencing the MLP useful life. Its value depends on conditions of all the elements of the MLP, thus, vibration signals are an important source of diagnostic information. However, for its practical application, mathematical models are required that adequately link physical events in the MLP to obtained numerical data. This paper proposes a regression mathematical model allowing performing vibration-based diagnostics of MLP equipment technical condition from bearing wear parameters and vibration. Data gathered from NM 10000-210 pump unit with STDP-8000 electric motor were used for construction of the model. The model allows calculating remaining life of an MLP for the current value of observation interval or from measurements, as well as determining design vibration value for a certain period of pump operation to compare it with an actual measured value. Application of the model allows optimizing periodicity of scheduled activities, timely revealing undesired changes in MLP operation and extending its operational life.
