Pumping oil through pipelines is provided by Main Line Pumps (MLPs), whose sta- ble 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 in- formation. However, for its practical application, mathematical models are required that ade- quately link physical events in the MLP to obtained numerical data. This paper proposes a re- gression mathematical model allowing performing vibration-based diagnostics of MLP equip- ment 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 in- terval 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 al- lows optimizing periodicity of scheduled activities, timely revealing undesired changes in MLP operation and extending its operational life. 1. Introduction One of the main condition for stable development of pipeline transportation of oil and petroleum products is ensuring reliability, safety and efficiency of operation of oil pumping equipment, including that of main line pumps (MLP). At that, reliability and economical operation of the pumps themselves is determined by a number of factors, such as quality of manufacturing, operating conditions, adaptability, timeliness of maintenance, etc. Increased vibration makes the most adverse effect on reliability of pumping units. About 38-45% of all centrifugal pump failures happen due to vibration, at that 42-53% of all pump failures are due to failures in face seals and bearings [1].

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
