| Abstract: | Trash rack of pump station is indispe is an auxiliary facilities. The research progress on nsable for stability and safety of pump assembly though it hydraulic resistance, vibration, rust-easten and corrosion, and clearing feculence is introduced which appeared during the application of trash rack of pump station. The head loss of trash rack is also analyzed. Based on the characteristics of pump assembly, the influences of hydraulic resistance of trash rack and feculence on pump unit operation are investigated. General situation of rack feculence-clearing equipment at home and abroad is also briefly introduced. The structures and forms of trash rack are analyzed and arched trash rack is put forward. The structure, layout and installation of trash rack should be fully considered according to the peculiarity of flow sewage, and we should improve its property of clearing feculence and stability endurance by the application of new materials and techniques. The way of clearing feculence should take into account the property of management and operation. |
