Abstract

Описано насосное устройство, содержащее статор и ротор, имеющие лопатки с противоположными направлениями витков резьбы. Радиальный зазор имеется между лопатками статора и лопатками ротора, так что вращение ротора вызывает взаимодействие статора и ротора для получения системы для перемещения флюида в продольном направлении между ними. Работа насоса приводит к образованию флюидного уплотнения от края до края радиального зазора. Описанное устройство также может быть приведено в действие в качестве двигательного устройства при направлении флюида для перемещения в продольном направлении между статором и ротором. Наличие флюидного уплотнения обеспечивает отсутствие снижения эффективности насоса или двигателя даже тогда, когда радиальный зазор значительно больше обычных величин рабочих зазоров. Кроме того, наличие радиального зазора делает насосное/двигательное устройство идеальным для работы с высоковязкими и/или многофазными флюидами.
