Title: Experiment Study on Hydraulic Performance of Liquid Jet Gas Pump with Wide Range of Area Ratio
Abstract: The characteristics of the liquid jet gas pump's(LJGP) working performance were introduced,and its different performance should adapt to its different applications.The throat /nozzle area ratio m of LJGP is the main parameter that was studied in this paper.With the throat length fixed,the hydraulic performance experiments of single-stage LJGP were carried out with 15 kinds of area ratio(1.1025~110.25).The results show that there is a range of area ratio that keeps the pump working normally.The smaller area ratio could bring about the larger pressure ratio,and the larger area ratio of LJGP could lead to a larger gas/ liquid volume flow ratio.Under the condition of the given model LJGP and the water supply centrifugal pump,and judging by the efficiency,there is an optimal area ratio value which make the LJGP working more efficiently,this value is consistent well with the calculating result of the transformed Cunningham's empirical formula,and as for the small area ratio(m4.41),there is an appropriate working pressure value.The experiment results and the conclusions provide the basis for the LJGP's engineering applications.
