    • A wet electric motor driven pump (70) comprises a main pump (71), pumping a specified working fluid which is driven by a wet electric motor (72), operating submerged in the specified working fluid, and means for bleeding (98), prior to entry into the main pump (71), a portion of the specified working fluid from the total flow of the specified working fluid entering the wet electric motor driven pump (70) to form an auxiliary fluid flow, which auxiliary fluid flow is substantially all the fluid in which the wet electric motor (72) operates. The auxiliary fluid flow is also substantially all the fluid that is used to cool the wet electric motor (72) and to lubricate the wet electric motor (72) and main pump (71).
    • 湿电动机驱动泵(70)包括主泵(71),泵送由湿电动机(72)驱动的指定工作流体,操作浸没在指定的工作流体中,以及用于流出的装置(98), 在进入主泵(71)之前,来自指定工作流体的总流量的指定工作流体的一部分进入湿式电动机驱动泵(70)以形成辅助流体流,该辅助流体流动基本上 湿式电动机(72)在其中运行的所有流体。 辅助流体流动也基本上是用于冷却湿式电动机(72)并润滑湿式电动机(72)和主泵(71)的所有流体。
