Injectors (also called ejectors) are used to add chlorine gas to water treatment chlorination systems; Steam injectors use the Venturi effect and the latent heat of evaporation to deliver feed water to a steam locomotive boiler. Sandblasting nozzles accelerate and air and media mixture
This is the manner in which a steam injector operates. An additional use for the injector technology is in vacuum ejectors in continuous train braking systems, which were made compulsory in the UK by the Regulation of Railways Act 1889. A vacuum ejector uses steam pressure to draw air out of the vacuum pipe and reservoirs of continuous train brake.
The method of liquid injection at the venturi throat can also cause problems. Spray nozzles are used for liquid distribution because they are more efficient (have a more effective spray pattern) for liquid injection than weirs. However, spray nozzles can easily plug when liquid is recirculated. Automatic or manual reamers can be used to correct ...
The steam injector is a common device used for delivering water to steam boilers, especially in steam locomotives. It is a typical application of the injector principle used to deliver cold water to a boiler against its own pressure, using its own live or exhaust steam, replacing any mechanical pump.
The ADI (anti-detonant injection) system, an adjunct to the pressure carburetor found on large military piston engines, consists of a supply tank for the ADI liquid (a mixture of 50% methanol, 49% water and 1% oil), a pressure pump, a pressure regulator, a spray nozzle, and a control diaphragm that moves the carburetor enrichment valve closed ...
Venturi-type injectors are best utilized for small scale growing operations such as personal gardens. [5] Positive Displacement Injector - Positive Displacement injectors operate by filling a tank, with a fixed volume, with a concentrated solution that is injected into the water line which has a constant flow rate.
A venturi is also installed in each bore. The impact tubes are mounted in each venturi, placing them directly in the path of the incoming air. All of the remaining main components are attached to the body, and are interconnected with internal passages or external tubes or hoses. Boost bar with AMC showing impact tubes and boost venturi
Choked flow is a fluid dynamic condition associated with the Venturi effect. When a flowing fluid at a given pressure and temperature passes through a constriction (such as the throat of a convergent-divergent nozzle or a valve in a pipe) into a lower pressure environment the fluid velocity increases.
