[悬赏求助] Repeller Repeller

Repeller是国外一个水泵的部件，怎么翻译？请高人指点一下。

The term repeller was adopted to differentiate between a wind turbine's rotor and a propeller Propeller originates from Latin term propellere which means to move something forward Since a propeller makes air move and by doing that produces propulsion, the term applies well Repeller originates from Latin term repellere which means to repel Since a repeller does not truly repel wind, but converts wind power into mechanical motion, the term is less appropriate to characterize what a repeller does Therefore, some people claim that wind power converter is more suitable than repeller regarding wind turbine rotors

推进器，助推器等，和impeller接近。

其实这个东西就是我们国内所说的副叶轮，flowserve旗下Durco公司出的MarK3系列ANSI化工工艺流程泵上动力密封泵就用的这个，repeller翻译为挡板，阻隔器。

flowserve的样本中有介绍，中文样本ps-10-13-c，英文样本ps-10-13-e
