THE PATTERNS OF CHANGE IN VOLUME FLOW OF OIL PIPELINE IN THE PROCESSES OF STARTUPS OF PUMPING UNITS

The duration of transient process of change in volume flow in oil pipeline by startup of pumping unit in oil pumping station (OPS) was determined with the help of processed industrial data after experiments carried out on the working oil pipeline. For each of the three stages of the transient process were built polynomial models in change of volume flow of oil at the time on the OPS where was launched pumping unit of OM series. It was found out, that the actual value of abruptly changing volume flow of oil on the distance to the origin of the disturbance can be reliably described by an exponential function.
