Processes and Devices of Chemical Technologies Analysis of Operation of a Two-Stage Hydroejector Vacuum-Creating System and Determination of its Optimum Technological Parameters

The article discusses the special features of operation of hydroejector vacuum-creating systems. The flow diagram of a two-stage hydroejector vacuum-creating system is described and a calculation algorithm is given. The dependence of the yield of the components of the vapor-gas mixture on the temperature of the working fluid was analyzed and the required heating temperature of the working fluid was determined. A two-stage hydroejector vacuum-creating system was calculated and the dependence of the flow rate of the working fluid on the pressure and power consumption of the pumps was determined.
