摘要
An adjustable ejector with a spindle in the nozzle was developed for a wider adjustment range.An experimental study was carried out on the performance of the adjustable ejector.To change the spindle position axially the nozzle throat sectional area could be changed.The ejector flow parameters,such as flow rate,pressure and entrainment ratio,at different spindle positions were measured.The results showed that the adjustable ejector could be used in a wider range of fluid flow rate.When the throat area was reduced,the ultimate discharge pressure would be lower but the entrainment ratio would increase greatly.
An adjustable ejector with a spindle in the nozzle was developed for a wider adjustment range. An experimental study was carried out on the performance of the adjustable ejector. To change the spindle position axially the nozzle throat sectional area could be changed. The ejector flow parameters, such as flow rate, pressure and entrainment ratio, at different spindle positions were measured. The results showed that the adjustable ejector could be used in a wider range of fluid flow rate. When the throat area was reduced, the ultimate discharge pressure would be lower but the entrainment ratio would increase greatly.
