Discussion on the Application of Guan Lide in the Teaching of Water supply Network Design from the Perspective of Educational Psychology

Abstract

Water supply network design is an important part of the practical teaching of water supply and drainage science and engineering. Through water supply network design, students can cultivate their preliminary ability to independently write design instructions and draw design drawings. At the same time, it is of great significance for students to establish correct engineering moral quality. At present, many colleges and universities adopt epaneth in the course design of water supply pipe network. Although the interface is relatively simple, it mainly depends on manual drawing of pipe network and input data. The labor intensity is relatively high, the result expression is not rich enough, and there is no drawing function. It needs to be combined with other software to give full play to its advantages, Guan Lide is a series of pipeline design software developed on the basis of Hongye municipal pipeline software. It has the advantages of topographic map identification, pipeline plane intelligent design, vertical visual design, automatic marking, automatic table drawing and automatic drawing. It is widely used in design institutes and other units. In order to improve the employment competitiveness of graduates, It is necessary and urgent to master a piece of professional software. Therefore, starting from the significance of educational psychology to the design of water supply network system, combined with the current professional specifications, taking a county in Hunan as an example, it introduces in detail the input and processing of basic information, pipeline layout, hydraulic calculation of pipe network, selection of water pump, fire protection, accident verification and so on, It is concluded that firstly, the pipeline layout of the pipe erection software can be directly carried out on the CAD base map without drawing the pipeline map separately. Moreover, there are fewer manual calculations than EPANETH. Only the node flow can be calculated, and the software can automatically distribute the flow. In addition, the hydraulic calculation of the water supply network is mainly carried out by the inverse method starting from the control point, and the changes of the water pressure and flow of the pipe network are clear at a glance, Finally, the appropriate pump can be directly selected according to the node parameters of the back calculation water source pressure adjustment calculation, which is very convenient and reliable. When checking the fire accident, it can quickly meet the requirements by changing the pipe diameter in the table. In short, Guan Lide software is a more professional software with convenient operation, and has more advantages in the preliminary design of water supply network, However, when carrying out multi pipeline design or construction drawing design, it needs to master a lot of professional knowledge and operation skills, and further study is needed to be able to apply flexibly.
