Abstract
Способ снижения сопротивления движению поездного состава и снижения износа системы «колесо-рельс», позволяющий реализовать увеличение коэффициента сцепления между колесами локомотива и поверхностью рельса при помощи системы подачи песка, состоящей из форсунки песочницы и выходной песочной трубы, отличающийся тем, что для предотвращения попадания оставшегося на поверхности рельса песка под колесные пары состава, при прохождении последней колесной пары локомотива, к системе подачи песка устанавливается система сдува песка, состоящая из дополнительного воздухоотвода, входного отверстия, пробки, контргайки, регулировочного болта, удерживающего болта, направляющего сопла и выходной горловины, причем горловина выполнена зауженной, для увеличения скорости выходящего наружу через выходную трубу воздуха. The way to reduce the resistance to movement of the train and to reduce the wear of the wheel-rail system, which allows to increase the adhesion coefficient between the locomotive wheels and the rail surface using a sand supply system consisting of a sandbox nozzle and an exit sand pipe, characterized in that to prevent the remaining on the surface of the sand rail under the wheelset of the train, when passing the last wheelset of the locomotive, a sand blowing system is installed to the sand supply system, consisting of from an additional air outlet, inlet, plug, locknut, adjusting bolt, retaining bolt, guide nozzle and outlet neck, the neck being made narrower to increase the speed of the outgoing air through the outlet pipe.
