Abstract Considering the problem that the leakage of liquid seriously affects the safety of submersible pumps,an online device to resolve the harm of leakage of liquid to submersible pumps was designed.In order to compare the performance of two kinds of nozzles,expansion and non-expansion,4 different-sized distance of mixing tube to nozzle and 6 different-sized mixing tube diameter were designed.Experiments were done in the same test-bed.The results show that liquid leaking excluder devices with the expansion nozzle have better performance,the best distance of mixing tube to nozzle is 1.67 times the diameter of nozzle throat,and the best diameter is 2 times the diameter of nozzle throat.The liquid leaking excluder device after optimization can solve the problem of fluid leakage better.
