Study on the Hydraulic and Energy Loss Characteristics of the Agricultural Pumping Station Caused by Hydraulic Structures

The pumping station is an important part of the agricultural irrigation and drainage system. sump one common water inlet types stations. In sump, to facilitate installation maintenance equipment, some hydraulic structures, such as pump beams, platforms chest walls, are added sump. At present, impact structures in on performance device not clear, so this paper focused characteristics entropy generation by using numerical simulation methods. results showed that has greatest efficiency device. coefficient increased after adding a beam decreased about 2% platform retaining wall. Results also will lead uneven distribution especially vicinity structures. wall increase total which means loss accordingly. Hence, addition beam, other should be avoided
