An ejector is used to achieve a vacuum without using moving parts. It works on the Venturi effect principle. The ejector is an industrial device used in several applications and is particularly well suited for suction and compression operations of gazes or liquids.
Quick vacuum in a high volume chamber
- Startup Ejector
Set a vacuum within a 5100 m3 chamber under 150mBar abs in 40 minutes .
Maintain an installation under vacuum
- Multi levels Vacuum groups
When the compression rate is higher, it is necessary to provide several ejectors in series with intermediate condensers.
Two levels Vacuum group with intermediate and final condensers' tubes - Aspiration of 210 Kg/h of air and hydrocarbons at 110 mbar abs.
Air ejector allowing to set up a low suction pressure and avoids pump cavitations. Steam Ejector allowing to reach lower pressures up to 0,3 mBar abs (See Vapydro)
Priming centrifugal pumpsThe ejector is mounted on a buffer tank and ensure the vacuum priming of the pump and its suction line. The instrumentation mounted on the balloon allows to control the whole system.
Sampling under vacuumThis device, using air or nitrogen as a working fluid, allows to collect a sample of a product being developed within a chemical reactor under vacuum.
Transfer / Evacuation
In the following configuration, the tank contents may either be evacuated to a drainage ditch or into a tank located at a higher altitude.
The ejector may also be used to create a vacuum depression in the transfer circuit and thus initiate a siphon. The vacuum production occurs only during the boot of the siphon.
The dilution of powder in a liquid engine can be achieved using an ejector.
Examples of others applicationsShip building:
- Purges de of bilges of ships.
- Purges of boats' sanitary.
- Ejectors of steam - recovery of the air and water vapor when released
- Ejectors with very low compression ratio for recovering harmful gases in industry.
- Due to their robustness and ease of use ejectors offer multiple application possibilities. Feel free to contact us.
