Abstract: The important aspect in pumping station's energy saving is to reduce pipeline resistance so as to raise pipeline efficiency. There are two ways for raising pipeline efficiency: adding drag reducer and improving fluid moving boundary condittion. The arlicle gives major introduction to the propertise, charaiteristics and application of a newly developed drag reducer, analyzes basic factors affacting its properties and its main advantages, and discusses the relationship between pipeline energy saving and pumping station energy saving.
