EJECTORS

2 inches Hg. Abs. to which the steam jet ejector can discharge. The result is a low priced and efficient vacuum pumping system. In Europe, an interesting equivalent to the water ejector is a cen- trifugal water jet ejector which combines a centrifugal pump with the ejector principle and which recirculates the motive water han-.

Water jet air pump theory and performance. - Calhoun: The NPS ...

The liquid jet gas pump is simple in construction, has no moving parts, and is used primarily for pump- ing gases containing some condensable vapors, such as water vapor, solvent vapors under a vacuum, or others which would be harmful to mechanical pumps. Statement of the Problem. The jet pump, although in use for...

Basic principles of vacuum technology, brief overview - Festo

method achieves only a relatively low vacuum level despite a high suction rate. Principle. • The most important components are the jet nozzle (venturi nozzle) ..... Our atmospheric conditions can also be compared with conditions under water. We live at the bottom of a “sea of air”. The gravitational force of the air above.

Aspirator (pump) - Wikipedia

An aspirator is a type of ejector-jet pump, which produces vacuum by means of the Venturi effect. In an aspirator, fluid (liquid or gaseous) flows through a tube that first narrows and then expands in cross-sectional area. When the tube narrows, the fluid pressure decreases. In this narrow area the fluid velocity must increase...

Schutte & Koerting - Steam Jet Vacuum Pump

517 Steam Jet Vacuum Pump operates on the steam jet principle, utilizing the energy of steam to create vacuum and handle process gases. Steam under pressure enters at the nozzle and produces a high velocity jet. This jet action creates a vacuum that draws in and entrains the suction gas. The mixture of steam and gas...

Water ejectors

Water ejectors are vacuum pumps, driven by a high pressure water (or similar medium) or steam. They use kinetic energy of the driving medium to suck in gases, vapors or other liquids and then discharge the resultant mixture against a counter pressure. Turbine Works manufactures water ejectors for industrial and marine...

How do ejectors work? Solutions for jet ejectors, jet pumps and ...

Working principle and more information about Koerting ejectors. ... Jet pump, ejector, motive media pump, injector - many names, same design and working principle ... The lower sectional model shows the internal construction of a jet pump which generates a vacuum on the suction side by means of steam as a motive...

Transvac - How an Ejector Works - YouTube

May 13, 2015 ... Discover the basic principles behind Ejector technology. A Transvac Ejector (venturi, eductor, jet pump) operation is based upon Bernoulli's Principle which ...

Basic principles of vacuum pump selection and operation

found in process industries: steam jet vacuum pumps and liquid ring vacuum pumps. Steam jet vacuum pumps . . are used to produce vacuum, by using the ener- gy of a motivating fluid (steam) to entrain the pro- cess vapours and inert gases.The steam jet vacu- um pump is normally called a “steam jet ejector”. (Figure 2)...
