泵吸入口 – 气体分离器
The gas separator design works in a similar fashion to a centrifuge. It cause the heavier fluids to be forced to the outside, through the crossover and up into the pump, while the lighter fluid (vapor) stays toward the center, and exits through the crossover and discharge ports back into the annulus.
Primary Functions 保护器主要作用

To compensate oil volume in the motor 补偿电机油体积变化 To keep well fluid out of the motor 防止井液进入电机 To carry the upthrust or downthrust 承载轴向止推力
Hub Shroud 盖板 Vanes 叶片 轮毂

The impeller’s job is to transfer energy by rotation to the liquid passing through it, thus raising the kinetic energy 叶轮的作用是把能量传递给流体，增加其动能

Positive Seal Protectors 胶囊式保护器
For applications where the well fluid and motor oil gravities are similar or where a well is highly deviated, a different Protector design uses a "positive seal" or "bag" to physically separate the two fluids 应用在井液与电机油的比重相差不大或者高度倾斜井中

Each “stage” consists of an impeller and a diffuser. 每一泵级由一个叶轮和一个导壳组成。
Pump Impeller
潜油泵叶轮

A centrifugal pump creates pressure by the rotation of a series of vanes in an impeller 离心泵是通过转动叶轮中一系列叶片产生压力
Pump Diffuser
潜油泵导壳
The diffuser section then converts this energy to potential energy, raising the discharge pressure 导壳是将由叶轮产生的流体的动能转化成势能，增加排出压力
