Problems solved by technology

On the one hand, the comparison of the performance of pumps with different specific speeds is not intuitive, which often results in the selected water pump being not optimal; optimal conditions
Although all large-scale water pumping stations conduct performance tests of water pump model devices, there is still no perfect theory and method for predicting the performance of water pump prototype devices, and the engineering performance of the designed pumping station cannot be accurately predicted in engineering design

Abstract

The invention relates to a pump type optimized design method based on water pump characteristic three-dimensional spatial patterns of a pump station. The pump type optimized design method comprises the following steps: step (1) carrying out regression on characteristic parameters of a plurality of water pumps by adopting a moving least square method to form a plurality of water pump characteristic three-dimensional spatial pattern curved surfaces; step (2) selecting the optimal water-pump pump type according to the plurality of water pump characteristic three-dimensional spatial patterns and characteristic lift of the pump station; and step (3) determining various parameters of the optimal water-pump pump type. According to the pump type optimized design method, the three-dimensional spatial patterns are adopted for expressing the performances of the water pumps, so that straight comparison for the performances of the water pumps is convenient, and the water pump with the optimal specific speed, a water inlet runner type and a water outlet runner type are conveniently selected; and water pump prototype device performance predication can be carried out according to the water pump model device characteristic test results which are carried out according to the selected water pump, the water inlet runner type and the water outlet runner type to serve as the main component content of engineering design, so that operation and management of pump station engineering construction are guided, and the needs of practical application can be met very well.

Description

technical field [0001] The invention belongs to the technical field of pump type optimization for water conservancy engineering pumping stations, and in particular relates to a pump type optimal design method for pumping stations based on three-dimensional space graphics of water pump characteristics. Background technique [0002] The pump type selection and parameter determination of large-scale low-lift pumping station are the key content to determine the success or failure of pumping station engineering design. All structural dimensions and engineering investment in pumping station engineering depend on the selection of pump type and the determination of pump parameters. At present, the traditional design method mainly relies on the experience of the designer. According to the head and flow parameters of the pump station, a pump with a certain specific speed is selected, and a water pump device is formed with different types of inlet and outlet channels. The corresponding...
