Improving Efficiency of Equipment of Two-Stage Vacuum Creating Systems

The article examines the distinctive features of operation of a two-stage hydroejector vacuum creating system and describes the process scheme. The dependencies of the yield of the components of the gas-vapor mixture from the working fluid of the second stage and the heat consumption of the two stages on the temperature were analyzed and the optimal conditions for the process were determined. Schemes of separators with replenishment are given. The influence of the location of the replenishment point on the separation efficiency was analyzed and the disadvantages of the existing two-stage vacuum creating systems were identified. Technical solutions are presented to improve the efficiency of the main equipment of the two-stage vacuum creating systems. The advantages are well-founded and sketches of the developed structures are presented.
