The Establishment Of The Experimental Facility Of A Dredge Pump And Hydraulic Transport System

In China, there is a huge amount of sediment deposited in rivers, lakes and reservoirs, which makes treatment by dredging very arduous and difficult. However, the experimental facilities in China for dredging technology are rather poor.Dredging pump and hydraulic transport experimental system proposed in this paper is mainly used for the experimental study of dredging pump performance and the solid-liquid two-phase flow in pipelines. The author actively paticipates in the design, installation, and trial tests of this experimental system. A data acquisition and processing software is developed by using Lab VIEW. In order to guarantee the safe and steady operation of the experimental system, a multipoint temperature measurement and alarm instrument with economical uitility is developed and it has been successfully used in the above system. In addition, cavitation is a difficult problem in hydraulic machinery. On the basis of a great deal of literature review, the author is also involved in the design of cavitation test facility. The work of this paper lays the solid foundation for the experimental research on dredging pump performance and hydraulic transport properties.
