Abstract

Предложен электрический погружной насос, обладающий улучшенными вибрационными характеристиками по сравнению с обычными электрическими погружными насосами. Указанные насосы с улучшенными характеристиками содержат электрический двигатель, механически соединенный с нагнетательной секцией. Улучшенные вибрационные характеристики указанного насоса обеспечиваются благодаря наличию по меньшей мере одного роторного подшипника, выбранного из группы, включающей роторные подшипники с шевронными канавками, пороговые роторные подшипники, роторные подшипники с окружной канавкой и комбинации по меньшей мере из двух любых из вышеуказанных роторных подшипников.
