Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to
Following embodiments.
A kind of drainage pumping plant water pump operation performance diagnogtics method, as shown in figure 1, including step：
S1：Specified displacement of each water pump in setting time section is loaded into, specified displacement is with water pump nameplate flow × water
