THEORIES OF OPERATIONAL CALCULATION FOR NUMERICAL MODELLING OF TRANSIENTS IN THE BRANCHED OUT MAIN OIL PIPELINE EQUIPPED WITH THE CENTRIFUGAL PUMP UNIT AT CONSECUTIVE SWAPPING VARIOUS SORT OF MINERAL OIL

Now at operatively-dispatching management of processes of a conclusion of the branched out main branched out main oil pipeline on the set mode at consecutive swapping various sort mineral oil, pump units in corresponding pump station join consistently at certain pressure of a brace before them. This fast start-up of the corresponding pump unit probably occurrence of hydraulic blow from for sharp increase of pressure in the oil pipeline. This circumstance can be at the bottom of an exit transmission the engine of pump station in the course of start-up out of operation because of an overheat of its starting winding.
