摘要: A pump includes one or more stages, each stage including a tubular housing and a mandrel disposed in the housing. The mandrel includes a rotor rotatable relative to the housing and having: an impeller, a shaft, and one or more helicoidal blades on an outer surface of the impeller. The mandrel further includes a diffuser: connected to the housing, having the rotor shaft extending therethrough and having a plurality of vanes on an outer surface thereof. Each vane has an arcuate portion and a longitudinal portion. The diffuser further has a channel formed between an adjacent pair of vanes. The pump further includes a fluid passage formed between the housing and the mandrel.

摘要: A motor includes two or more sections. Each section includes a submersible tubular housing and a stator core disposed within the housing. The stator core has one or more lobes and each lobe has a winding wrapped therearound. The motor further includes a rotor disposed within the housing and including a shaft and a rotor core. The rotor core has two or more lobes. Each section is incrementally oriented so that the sections may be operated to mimic a multi-phase motor.
摘要翻译: 电机包括两个或多个部分。 每个部分包括设置在壳体内的潜水管状壳体和定子芯。 定子芯具有一个或多个凸角,并且每个凸起具有缠绕在其周围的绕组。 电动机还包括设置在壳体内并包括轴和转子芯的转子。 转子芯具有两个或更多个凸角。 每个部分是递增取向的,使得这些部分可以被操作以模拟多相电动机。
