Abstract:In order to enhance the performance of swirling jet pump device, a new swirling jet pump device was designed.Choosing three different area ratio swirling jet pumps and corresponding non-rotating jet pumps as the study object, by changing the flow ratio, changing characteristics of the swirling jet pump device performance with jet pump area ratio and flow ratio was studied. Results showed that the optimal area ratio of the swirling jet pump is less than that of the irrotational jet pump. Compared with the irrotational jet pump,when the swirling jet pump′s area ratio is bigger or smaller, its pressure ratio and device efficiency are obviously superior to the irrotational jet pump′s; while its area ratio is close to irrotational jet pump′s, its pressure ratio and device efficiency are a little better than the irrotational jet pump′s. Compared with the irrotational jet pump device, the best efficiency points of swirling jet pump device move to big flow ratio direction, which will increase the efficient district range of device performance. Swirling jet pump device′s pressure ratio can increases 0.01 at most, equivalent to 5%-10% of irrotational jet pump device′s;while its efficiency can increases 4% at most, equivalent to about 25% of irrotational jet pump device′s.
