Abstract

Изобретение относится к конструкциям рабочих колес центробежных насосов для перекачки гидроабразивных жидкостей и предназначено для повышения ресурса работы насоса. При работе насоса наиболее интенсивно изнашиваются ведущий диск 5 и лопатки 7 в области входных и выходных кромок 8 и 9. Длительность абразивного износа определяется суммарной толщиной ведущего диска 5 и толщиной отбойных лопаток 10. Расположение участков 12 и 13 отбойных лопаток 10 напротив входных и выходных кромок 8 и 9 лопаток 7 позволяет увеличить толщину диска 5 в области максимального износа и предохранить от локальных разрушений в виде сквозных отверстий ведущий диск 5. 3 ил.
