![]() Through this nozzle, its velocity increases and consequently low pressure exists at that point on nozzle. A high pressure motive fluid, typically steam, enters the steam ejector and passes through the nozzle. As an experienced provider of Engineering Answers since 1936, Graham maintains the most comprehensive database of actual steam ejector performance information available today.Ĭombine Graham Steam Jet Ejectors with other Graham equipment, such as Process Condensers and Liquid Ring Pumps, and you have a single source of supply and a responsible, total solution for process equipment needs. A steam ejector basically comprises of three (3) elements: a nozzle, a mixing chamber and a diffuser. Featuring proven, unique internal geometries and tightly tolerance-controlled steam nozzle configurations, Graham ejectors produce very low steam consumption and highly efficient operation. Compact design and comparatively lightweight which enables overhead installations. Graham has mastered Steam Ejector design. The SJT Steam Jet Thermocompressors features and benefits include: Simple construction Available in alternative machined materials for increased abrasion resistance. ![]() ![]() In addition to operating well into the micron HgA range, they can also operate well above atmospheric pressure. Ejector systems are available in unlimited range of capacities and can produce as low as 1 milli torr or 0.133Pa with steam pressure as low as 2 ata or 202.6. Ejectors can be designed to operate without steam as their pressurized (motive) source. Machining operation and presence of water droplets cause increase the surface roughness of wet steam ejector walls and change its performance in the refrigeration cycle. It is usually used to increase vapor or liquid pressure or to make vacuum. Virtually maintenance-free with no moving parts, they can be fabricated from almost any material, and can be used in every industry that requires vacuum. Steam Jet Ejectors - the largest vacuum producing devices available - are used in the most demanding of applications. ![]()
