Problems solved by technology

[0002] The main equipment of urban drainage pumping stations is water pumps. The operating status of water pumps determines the performance of pumping stations. At present, the status monitoring of pumping stations is often limited to the maintenance process of water pumps, which makes the diagnosis of their operating performance not easy to carry out online. , if online diagnosis is required, some complex monitoring devices need to be used, and many of these devices are embedded in the water pump to monitor the performance of the water pump in real time. Customization, plus the water pump also needs to be optimized for these sensors so some adaptation

Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0039] A method for diagnosing the operation performance of water pumps in drainage pumping stations, such as figure 1 shown, including steps:

[0040] S1: Load the rated displacement of each water pump within the set time period. The rated displacement is measured or counted by the flow rate on the pump nameplate × the start-up time of the pump. The start-up time is the time interval of the set time period. Specifically, the rated The displacement is:

[0041] M=Q×T

[0042] Where: Q is the flow rate marked on the nameplate of the pump;

[0043] This has certain advantages: such ...

Abstract

The invention relates to a drainage pumping station water pump operation performance determining method and equipment. The determining method comprises the following steps: S1: loading rated drainage volumes of water pumps within a set time period; S2: collecting the actual drainage volumes of the water pumps within the set time period; S3: determining the operation performance of the water pumps and generating related coefficients according to the actual drainage volumes and the rated drainage volumes; S4: displaying the determination results to maintenance staff in a visible manner. Compared with the prior art, the method provided by the invention has the advantages as follows: the operation performance of the water pumps is determined by calculating the related coefficients according to the actual drainage volumes of the water pumps, collected within the set time period, and the rated drainage volumes, so that the determination results can reflect the operation states of the water pumps more objectively; besides, the determination results are displayed to the maintenance staff in a visible manner, so that the displayed results are more visual, and the experience of maintenance staff is better.

Description

technical field [0001] The invention relates to a water pump operation diagnosis technology, in particular to a water pump operation performance diagnosis method and diagnosis equipment in a drainage pumping station.
