Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. A flow chart of an automatic optimization method for the water outlet channel of a pump device is as follows: figure 1 shown. Taking the outlet channel of the shaft-extension tubular pump device as an example, the step (1) is used to carry out a three-dimensional mathematical parameterized model for the outlet channel of the shaft-extension tubular pump device. The mathematical expression is as follows: It is equal to the diameter of the outlet section of the guide vane body; the dimension height Hc and width Bc of the outlet section of the outlet channel, and the length L of the central axis of the outlet channel are used to calculate the equivalent diffusion angle θd of the water channel and determine the design flow Qi of the pump device but

Abstract

An automatic optimal design method for the outlet channel of a pump device, which belongs to the field of pumping station engineering technology, uses a non-dominated solution sorting genetic algorithm to optimize and solve the outlet channel, and establishes a three-dimensional mathematical parameterization module of the outlet channel shape, and the outlet channel The three-dimensional turbulence numerical solution module, the objective function solution and the integration module, the principle of the present invention is clear, compared with the prior art, the automatic optimization method of the outlet channel of the pump device can reduce the workload of the pump station designer and speed up the construction of the project Pre-research progress saves the time period of pumping station scheme comparison and achieves the purpose of speeding up pumping station construction. The present invention automatically optimizes the water outlet channel on the basis of considering the residual circulation at the guide vane outlet, so the obtained result is closer to the actual situation of the water outlet channel.

Description

technical field [0001] The invention belongs to the technical field of pumping station engineering, and relates to an automatic optimization design method for a water outlet channel of a pumping device, in particular to a low-lift block-based pumping station. Background technique [0002] Pumping station is an important water conservancy infrastructure, which plays a key role in large-scale farmland and regional drought resistance, flood control and drainage, urban water supply, sewage discharge and cross-basin water transfer. More and more attention will be paid to the optimization of the design of the outlet channel of the pumping station. In 2015, the No. 1 Central Document "Several Opinions on Intensifying Reform and Innovation to Accelerate Agricultural Modernization" mentioned the importance of irrigation and drainage pumping stations serving agriculture. The comprehensive management of the water environment and the improvement of the urban flood control standard syste...
