Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment is implemented premised on technical solution of the present invention, give detailed mode of execution and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
A kind of drainage pumping plant water pump operation performance diagnogtics method, as shown in Figure 1, comprises step:
S1: be loaded into the specified water displacement of each water pump in set time section, specified water displacement carried out measuring or adding up with water pump nameplate flow × water pump opening time, the available machine time is wherein time lag of set time section, and concrete, specified water displacement is:
M＝Q×T
Wherein: Q is the flow that water pump nameplate marks;
Do like this and there is certain advantage: be as Statistical Criteria is consistent, simple and convenient, build with operation expense low.
