A vacuum ejector, or simply ejector is a type of vacuum pump, which produces vacuum by means of the Venturi effect.. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.
It is a fluid-dynamic pump with no moving parts except a valve to control inlet flow. Depending on the application, an injector can also take the form of an eductor-jet pump, a water eductor or an aspirator. An ejector operates on similar principles to create a vacuum feed connection for braking systems etc.
Jet noise may be reduced by adding features to the exit of the nozzle which increase the surface area of the cylindrical jet. Commercial turbojets and early by-pass engines typically split the jet into multiple lobes. Modern high by-pass turbofans have triangular serrations, called chevrons, which protrude slightly into the propelling jet.
The steam ejector is a popular form of pump for vacuum distillation and freeze-drying. A jet of steam entrains the vapour that must be removed from the vacuum chamber. Steam ejectors can have single or multiple stages, with and without condensers in between the stages. While both steam ejectors and diffusion pumps use jets of vapor to entrain ...
Adding ankle weights to your walking routine could provide some benefits, like increased calorie burn and better muscle activation, say experts. Here’s how to use them.
After a year filled with animated inner emotions, mutants, aliens, gladiators and witches, the new year will bring a crop of new (or, newly revisited) movies to choose from, as always.
